Goals

What are the goals for the family medicine rotation?

 

  • Learn about what is family medicine
  • Learn about what is the scope of family medicine - how family physicians relate to the community
  • Learn some outpatient medicine
  • Dr Forman is a wonderful mentor
  • Learn about an approach to the patient that may be (or may not be) different from hospital medicine.
  • If you schedule 60 patients a day you are crazy and you will never have enuf time with your patients
  • There are Soooo many different ways to approach a given situation or problem
  • Emotional psychologial issues are adressed in family medicine
  • Family Medicine is about building connections with patients .. sometimes you cry .. sometimes the patients cry.  It's ok
  • Family physicians can treat patients in a WHOLE manner - with appreciation and knowledge of the family dynamics, etc ..

Uterine fibroid

Background: A uterine fibroid is the most common benign (not cancerous) tumor of a woman's uterus (womb). Fibroids develop with the uterine wall or attach to it. They may grow as a single tumor or in clusters. Uterine fibroids can cause excessive menstrual bleeding, pelvic pain, and frequent urination.

Question: What is the treatment for fibroids?

Discussion: Treatment of fibroids depends on your symptoms, the size and location of your fibroids, your age (how close you are to menopause), your desire to have children, and your general health.

In most cases, treatment is not necessary, particularly if you have no symptoms, have small tumors, or you have gone through menopause. Abnormal vaginal bleeding caused by fibroids may require D&C. If no malignancy (cancer) is found, this bleeding often can be controlled by hormonal medications.

Surgery options for treatment have both risks and benefits.
  • Myomectomy is the surgical removal of the fibroids only. This can be accomplished through hysteroscopy, laparoscopy, or, less frequently, an open procedure (an incision in your abdomen). Myomectomy has also been shown to have a decreased likelihood of injury to the bowel, bladder, or ureter than hysterectomy. The uterus is left intact in this type of procedure, and you may be able to become pregnant.
  • Hysterectomy is the surgical removal of the uterus. It is the most commonly performed surgical procedure in the treatment of fibroids and is considered a cure. Less blood loss has occurred using hysterectomy than myomectomy.
  • Uterine artery embolization of the arterial blood supply to the fibroid. This method may prove to be a good option for women if other methods have not worked or who do not want surgery or may not be good candidates for surgery.

    Lay off the herbs

    Remember when that Baltimore Orioles pitcher died supposedly from using Ephedra? Ephedra and a bunch of other supplements labeled as herbs by the FDA are not monitored as stringently as prescription medicines and potentially can cause side effects.  I wanted to find out just how bad one of the most famous supplements on the market was.

    Ephedra was evaluated by the FDA and this study reviewing the adverse events appeared in the NEJM.  Most of the adverse events were either cardiovascular or neurologic in nature, and some resulted in death or permanent disability.  Several case studies are included in the article and basically, the finding is that supplements containing ephedra can be lethal and potentially cause harm to the person taking them.

    However, there are serious questions about this study...I wonder just how effective a supplement would be if it was monitored by the FDA and it had standardized doses.  It's possible that many of the adverse events might be attributed to misuse of the supplement.  Because the supplements weren't monitored by the FDA and no warning labels were placed on them, a false sense of security was created.  Misuse and overdose were common.

    The lesson to be learned from ephedra and other supplements is that one should be cautious with any herbal remedy is stores.  They are not regulated by the FDA so you don't really know what is actually in the pill.  While the label might say a certain amount of a product is there, it might not be.  It's the physician's responsibility to be knowledgeable regarding certain herbal supplements and to caution their patients about the dangers of OTC products that don't have any standardization.  The next ephedra might be on the market right now. Hopefully it won't take a few deaths before it's discovered.

     


    Cord care

    The other day in the office we had a very concerned couple bring in their first newborn child.  The parents were concerned because the 12 day old's umbilical cord fell off but now his umbilicus was oozing and they were afraid it was infected.  Upon examination it was determined to be normal and no treatment was initiated, and the parents were reassured but told that it was very important to keep the area clean and to use alcohol wipes to prevent infection.

    I wondered what affect alcohol wipes or other modes of cord care had on the prevention of infection.  I found an article on the subject, and apparently it is under much debate.  There have been many studies on this, however it is surprising that there are no significant differences with infection rates between the different treatments, be it alcohol wipes, chlorhexidine treatment, or just leaving it dry.  Many studies I found showed that leaving it dry resulted in it falling off earlier with no difference in infection rates.  Yes, they may smell and be gross, but I think it may help parents to know that they need not obsess about keeping them clean, because they have enough to worry about already with a new baby.


    Reasons to treat toenail fungus
    We've heard that insurance companies don't want to pay for long, expensive treatments for toenail fungus because they see it as a cosmetic issue.  I think it goes beyond cosmetic since your toenail gets brittle, thick, and discolored and can cause many problems for patients.  And, I think in general it's pretty important to patients to get rid of the infection (i.e. it's not supposed to be there).

    Here are some reasons physicians can use to appeal to insurance companies to pony up and cure this infection.

    This study explains that diabetic patients are at risk for developing abrasions and ulcerations due to the combination of trauma and nail changes associated with onychomycosis (how's that for a big word?) due to impaired sensation of the diabetic foot.  These ulcerations can become seriously infected, and just adds insult to injury to the diabetic foot.  Due to impaired sensation, diabetic patients may not realize that there is added pressure from their shoes onto their thickened toenails.  And, this added pressure can also further decrease circulation to the toes.

    This case-control study (full-text PDF) showed that tinea pedis interdigitalis, tinea pedis plantaris, and onychomycosis are significant risk factors for acute bacterial cellulitis of the leg with odds ratios of 3.2, 1.7, and 2.2, respectively.  These are all readily treatable with pharmacological therapy (Lamisil, Sporanox).

    These treatments are indeed expensive and long, but there's a way to make it cheaper and more convenient for the patient.  This study showed that pulsed terbenafine (Lamisil) therapy was 50% less expensive and at least as effective as continuous therapy.  Continuous therapy was 250 mg/day over 16 weeks, and pulsed therapy was 500 mg/day for 1 week every 4 weeks over a 16-week period.  (I know which one I'd pick). 

    So there are reasons to treat toenail fungus, and it's not just cosmetic.  I think physicians should be willing to appeal to insurance companies on behalf of their patients to get this treatment approved because patients may end up suffering serious consequences down the road.



    Got Milk?

    This study compared nutrient and dairy consumption to hip bone mineral density (BMD) in black and white, women and men >60.  The Health Habit and History Questionnaire was used to predict BMD changes. 

    Interesting observations: Blacks had higher Ca++ intake than white (700 vs. 654 mg/d) and men had more intake than women (735 vs. 655 mg/d).

    In the cross-sectional study, there was no relationship between hip and femoral neck BMD and Ca++ intake in black and white women, but there was a relationship between the two in both races of men. HOWEVER, this study referenced two other studies that did show BMD improvements in hips and femoral necks in women taking Ca++ supplements.  Important: The Ca++ in dairy food was the only form of Ca++ that provided a benefit.  Ca++ in nondairy food showed NO relationship. 

    Dairy products also contain protein, Vit A, retinal, folate, thiamine, riboflavin, niacin, Vit B6, Vit C, Mg, K, Na, and Zn, which were also beneficial to overall health.

    In the longitudinal study (whites only) Ca++ supplementation DID REDUCE BONE LOSS from hip and femoral neck in patients who were getting only <1.5 servings of dairy products were consumed per day and the patient was <72 yo.   

    Ca++ recommended is 1200 mg/d, and the general population does not usually meet this recommendation.  I would recommend that all older patients get their requirement of Ca++ because, although it may not help...it won't hurt to see if it does.


    EXTRA EXTRA! READ ALL ABOUT IT! HPV VACCINE TO PREVENT CERVICAL CANCER!!!

    As we all know, cervical cancer is most commonly caused by infection with the HPV viruses 16 and 18. While women routinely undergo the ever-so pleasant speculum exam to hopefullY catch any signs of Cervical Intraepithelial Neoplasis (CIN). The signs often go undetected since HPV 18 is very hard to detect with a routine pap and unfortunately this too is the more likely culprit when it comes to progression to Adenocarcinoma.

    In the study, the investigators examined the incidence of cervical infections related to HPV-16/18 infection in 1,113 women (mean age, 20 years) randomized to receive three injections six months apart of bivalent HPV-16/18 VLP vaccine or placebo. A 27-month follow-up period included assessment of HPV infection by cervical cytology and self-obtained cervicovaginal samples.

    Incident cervical infection was defined as having at least one positive polymerase chain reaction assay for HPV-16 or HPV-18 DNA during the trial. Persistent cervical infection was defined as at least two positive assays at least six months apart for the same viral genotype.

    Results showed the vaccine to confer significant protection against HPV-16/18 infection: in women completing the study. The vaccine was 91.6% effective against incident infection (95% confidence interval [CI], 64.5 - 98.0) and 100% effective against persistent infection (95% CI, 47.0 - 100.0). The authors believe that success of this vaccination will be invaluable in reducing world-wide rates of cervical cancer but also agree that large scale trials and long-term follow ups are needed to confirm these preliminary findings. But stay-tuned we may be at the forefront of witnessing the end of an era and perhaps the beginning of a new, cervical cancer-free era!


    Are our kids getting too fat?

    Obesity in the pediatric population has become a worldwide epidemic and, if left uncontrolled, our young patients' "baby fat" will turn into a lifetime of medical problems.  Studies have found that long-term health complications in overweight children after a 40 year follow-up include increased rates of cardiovascular diseases, increased insulin resistence, digestive diseases, and increased mortality. 

    Ways to prevent obesity in children and adolescents include healthy eating patterns, an active lifestyle, and encouraging adolescents to increase their own responsiblity for a healthy lifestyle.  It has also been found that prolonged, exclusive breast feeding reduces the risk of being obese or overweight among school age children. 

    Excess TV watching has also been found to be a significant factor in obesity in children.  Watching TV not only decreases physical activity, but reduces the resting metabolism of the child.  TV also increases calorie consumption in children, either by munching on junk food while watching TV or by exposing children to adverstisements of food. 

    Treatment for childhood obesity requires a multidisciplinary approach including diet, exercise, and behavioral therapy. 


    Shelf Exam

    Evidently the 7 hours it takes me to write a  blog is not truly appreciated by the vast majority of those who vote.  I mean, WOW, 3.2pts for finding the best articles on chronic pain management, that hurts. C'est La Vie,...I'm over it, no hurt feelings and thanks to those who read and voted.

    However, with the upcoming shelf exam and my confidence low in my ability to do well, I decided to give you all what you want in the hopes of a higher grade Do shelf exams accurately refelct knowledge and skill?

    1.This article is my favorite. It finds subjective evaluation of surgical knowledge by faculty and residents correlates poorly with performance measured objectively via shelf exams.  They interprited this information to mean that subjective and oral evaluations should not be used to evaluate students.  I took this to mean shelf exams may be less suited to evaluation.  

    2.  This article says that we actually do learn what is on the shelf exam in our rotations,...generally.   I know I didn't hear about Osgood-Schlatter Lesion in the office and certainly didn't expect to.

    3. Well then, maybe we are being taught in the wrong way.  Maybe we should have strictly a problem based approach?  The jury is still out.

    4. More bad news,  those who take the family medicine boards after internal medicine due better. (big surprise)

    5. We do have one great thing going for us, as this article points out. Evidently, community preceptor clerkship rotations provide as well and sometimes better educational experience as noted on standardized test (step 2) as those trained in the hospital.

    So don't worry...., the shelf will be hard ......, but its part of the process and helps those who have a large knowledge base but have difficulty applying it to a clinical situation. Good luck on Friday.


    Drink a beer a day to keep the doctor away!!!
    We've all heard that a glass of red wine with dinner is good for your heart, but what about beer? Researchers at the University of Western Ontario (UWO) have found that beer has the same antioxidant properties as red wine. Red wine was always considered to have the most benefit because it has about 20 times more polyphenols (which have the antioxidant benefit) than beer. But it turns out that the body absorbs equal amounts whether from beer or wine, thus having equivalent antioxidant effects. This is only true with moderate alcohol consumption and there is actually a risk of disease with larger intake of alcohol. For more info on this study, which will published in December, go to the UWO site.

    There was a review done prior to this study, which looked at all types of alcohol. They looked at 12 ecological studies, 3 case-control, and 10 cohort. The results provide evidence that all alcoholic drinks may be associated with a lower risk for coronary heart disease. It's an interesting review, which attributes the cardiac benefits of alcohol consumption to the rise in HDL levels as well as increase in levels of tissue plasminogen activator, decreasing the risk for thrombosis. Again, these benefits are only seen with moderate alcohol consumption.

    So, does this mean we can go tell all our patients to go drink because it's good for their heart? Of course not. But taking into account the patient's health history and risk for alcohol abuse, it is worth telling them that regardless of the type of alcohol, a little bit (1 drink for women, up to 2 for men) each day lowers the rate of heart disease and overall mortality.

     


    Mommy, can I sleep in your bed?

    The other day my preceptor and I were talking with the mother of a 1-year-old beautiful little girl. Her mom was a little concerned because every time she attempted to move her daughter from her own bed to the crib, the baby would cry and would not stop until she was brought back into the parents' bed. I kept thinking the rest of the day about the prevalence of this concern among parents - whether to allow a crying child to sleep with them in their bed or whether to exhibit "tough love" and leave them alone in their crib/bed. Bedtime can be a truly traumatic experience for many children due to the "fear of separation" that we learned so much about during our pediatric rotation. Thus weaning a child from the parents' bed may be easier if attempted prior to 9 months or after 2-3 years of age. For other children, it may be a very natural thing to sleep alone if they have always done so. Still others may have slept in their parents' bed early on and then been able to transition fairly easily to sleeping independently.

    In the articles that I have read on the topic, the opinions are as varied as the sky is vast. Proponents of co-sleeping or bed sharing claim that not only is this a natural behavior among most of the world's human populations (note this cultural comparison), but also that benefits to babies and young children are numerous. Benefits include: decreased anxiety for the baby when awakening in the middle of the transition from one sleep cycle to another (comfort & security of sensing the familiar smell, warmth, touch and heartbeat of the mother and father); synchrony between the sleep cycles of mother and baby (resulting in less exhaustion for the mother due to fewer episodes of awakening during deep sleep); increased ease and duration of breast-feeding for both mother and child; increased bonding between parents and baby and decreased incidence of SIDS (provided the parents are not obese, smokers or under the influence of alcohol). Advocates for babies and young children sleeping independently from their parents claim that co-sleeping has an increased risk of SIDS due to entrapment of the child (for example, between the bed and the wall or in a waterbed or under the parent's body) - especially if the parent is a smoker or under the effects of alcohol, suffocation among bedding and blankets. They also highlight the obvious obstacles that may be introduced into the sexual relationship of the parents. There is also a concern on the part of the American Academy of Pediatrics regarding the psychosexual implications of parents routinely sharing the bed with their children, among others.

    This article (click on Ovid Technologies, Inc.), I thought, did a fairly good job at reviewing each of the major areas of research related to co-sleeping (several expert authors are cited). Okami et. al. conducted this prospective study of bed sharing in 205 families (154 nonconventional families and 51 conventional families) from 1975 - 1994. A certain child in each family was followed from 3rd trimester in-utero until 18 years of age. In early childhood bed sharing "was found to be significantly associated with increased cognitive competence measured at age 6 years, but the effect size was small." When assessed at age 6, children who had slept with their parents were not found to have sleep problems, sexual pathology or other adverse consequences. Finally, assessment of the same children at age 18 showed no connection of bed sharing in infancy/childhood to pathology or other problems, nor did it show any beneficial consequences. The authors thus contend that healthcare providers, when approached by concerned parents on this issue, should have a conversation with the parents about the all the evidence that exists based on studies done to date and should discuss the advantages and disadvantages of bed sharing as the parents view them. Ultimately, the decision will lie in the hands of the parents.


    To bare arms?

    Htn is one of the most commonly treated diseases in primary care. As it rarely presents with symptoms its diagnosis heavily depends on BP readings in physicians office. The question then becomes how accurate these measurements are and whether or not they are dependent on  technique such measurement on bare arm vs. a sleeve.

    This article examined the effects of measuring blood pressure on subjects' rolled up sleeves, over the sleeve, or on the a bare arm. Surprisingly, it concluded that when using a sphygmomanometer cuff there is no statistical difference on blood pressure measurements based on the degree of clothing. This has a great implication for the busy GP reassuring that technique should not prevent from performing measurement.

    However, for patients with known HTN it is recommended that measurements should be taken under standardized conditions, i.e.: a bare arm.  These patients tend to have a greater deviation from the mean when their arm is clothed with lower pressures. This can give false assurance that managent is better then what is actually is.

    Take home message: when rushed for time, taking a BP with clothed arm is OK. Ideally for HTN patients it should be done on a bare arm!


    Do Soy Products cause Precocious Puberty?

    A 6 year old girl camel for a routine check and was found to be at tanner 2 for pubic hair and breast development.  The doc inquired about her diet and recommended that she cut down or exclude chicken from her diet and exclude soy milk and other soy products from her diet.  I knew of hormones in poultry and cow's milk, that's why I've been feeding my son Soy Milk and not cow's milk for the past year and a half.  I was surprised to hear that Soy product, "the healthy alternative" to hormone loaded cows' milk may also be unhealthy. 

    Precocious puberty is predominantly found in African American girls than Caucasian girls.  The rise in precocious puberty over the last three decades has been thought to be due to the increase in use of hormones in cattle and the environment and the increased consumption of meat and foods on a whole.  One study of girls in Africa showed that these girls reached puberty at a later age regardless of socioeconomic status than girls in the Western World.

    Phytoestrogen is an estrogen-like compound that is found in soy products.  phyotoestrogen along with other soy proteins have been found to be beneficial for menopausal women.  It reduces their symptoms of hot flashes etc.  It has also been found to help decrease LDL, while increasing HDLs.  

    Since the introduction of soy-based formulas in the 1970s many newborns and infants, especially those who are lactose intolerant are quickly introduced to Prosobee and other soy based formulas.   Sure, there are other environmental estrogens such as plastic baby bottles, nail polish, hair straighteners, filling in teeth, shampoos (It has not been proven that these shampoos lead to precocious puberty, but the level of estrogen found in them is certainly high enough to cause precocious puberty in girls), etc that may help cause precocious puberty, but so does Soy or so we think.

    All of the studies that have been done were done on animals for the obvious reason that we couldn't give soy products to newborns and infants to see if they develop precocious puberty or not.  At the end of the day, the best advice is to avoid products that may contain estrogen via the following ways:

    -eat organic meats, drug goat's milk or nuts milk

    -use low fat milk, skim milk, skim milk yogurt, hormones cling to fat

    -avoid drinking from plastic bottles or atleast heating up the plastic bottles, heating releases estrogen like substance into the food

    -Avoid using pesticides and herbicides in our yards, wash produce thorougly before feeding them to our children or buy organic fruits and vegetables

    -Flaxseed consumption reduces the effects of estrogen

    -Avoid estrogen containing shampoos, the labels usually read "placenta for deep conditioning or dry brittle hair".  Most commonly marketed to African Americans.

    -Avoid giving children soy formula and soy products if at all possible except for a small amount of fermented soy products. 

    I don't think we can afford to avoid estrogen containing products because an organic foods only lifestyle is very expensive.  Most people eat what they can afford.  It looks like more trips to the endocrinologists' offices.

    In case anyone was wondering, boys with increased consumption of estrogen-like hormones may experience delayed puberty or infertility.


    Digital mammography

    In our office, my preceptor routinely encourages women who are going to be having mammography for routine breast cancer screening to get "digital mammography". And so, I was wondering what the difference was, and whether digital was really better than traditional film mammography.

    The basic technology behind digital mammograms is the same as that of other digital imaging techniques. The images are created digitally and radiologists can then zoom, change contrast settings, and manipulate the images in any number of ways to get a better view. This patient centered site gives a basic overview, and states that some of the main advantages to the technology are fewer patient call-backs for additional images, and increased efficiency, but does it make any difference in efficacy?

    This American study and this Norwegian study both conclude that the sensitivity, positive predictive values, and overall cancer detection rates are similar between the two technologies. Neither study shows either technology to be superior to the other.

    However, there is still a strong push for the digital technology among many radiologists because of its potential future improvements. This long article (warning) talks about some of the reasons why: ease of image taking, processing, manipulating. And many people hope as the technology becomes more widely available, it will translate into increased cancer detection rates. Until then, it seems, traditional mammography is at least as good as digital.


    Persistant otitis externa

    This week, I saw a 42 year old woman suffering from a bout of otitis externa.  She had been seen several days earlier and had been given a prescription for neomycin/polymyxin B/hydrocortisone (Cortisporin otic) drops for her ear.  This solution normally covers the two major bacteria involved in otitis externa, Pseudomonas aeruginosa and Staphylococcus aureus.  However, this patient's symptoms had not improved with this treatment and her external auditory canal was swollen shut.

    A study (full text) of otitis externa compared topical neomycin/polymyxin B/hydrocortisone with topical ofloxacin.  They found that otitis externa infections were increasingly resistant to topical neomycin/polymyxin B/hydrocortisone while still susceptible to ofloxacin.  However, a separate randomized clinical trial found that Cortisporin and ofloxacin were equally effective in their cure rates.

    Considering this patient's failure to respond to the initial treatment, the doctor decided to switch her to the ofloxacin drops.  The patient was quite pleased with the change, especially since ofloxacin is administered only twice a day compared to Cortisporin's four times a day.


    Hypertension

    Treatment of Hypertension - What's the goal of therapy?

     

    This week I've decided to talk about the ubiquitous problem of hypertension, (this is a very basic overview of hypertension, but it's interactive, so have fun.) Of course, we're all aware of the many co-morbidities associated with hypertension and the importance of treating it.  There are different approaches to treatment which we should be aware of and while separate treatments may reduce blood pressure a comparable amount, there may be differences in the long-term outcome for our patients, which is the point.

     
    • This study compares the outcomes for elderly patients with hypertension treated with Angiotensin Converting Enzyme Inhibitors (ACEIs) and those treated with diuretics.  The major conclusion to the study is that patients, particularly elderly men, treated with ACEIs have better outcomes than those treated with diuretics despite similar decreases in blood pressure.
    • This study compares ACEIs and ACE Receptor Blockers (ARBs) in reference of preventing myocardial infarction.  The authors were unable to find a difference, which is fortunate for patients who can not tolerate ACEIs.
    • As this review states, there is evidence that Ramipril (Altace) reduces the rate of mortality in patients with hypertension.  However, further studies are necessary to determine if any of the ACEIs are better than one another.
     
    We are going to be treating patients with hypertension regardless of what we end up going into.  Therefore, we need to choose treatments that ensure the long-term safety of our patients, not just reduce the numbers on a scale.


    Antidepressants INCREASE suicidal thoughts in children and teenagers?

    Recently FDA ordered all antidepressants carry the warnings for increased risk of suicidal thoughts.  Previously, FDA reviewed 24 placebo-controlled trials of nine antidepressant drugs in children with psychiatric disorders.  The analysis showed a greater risk of suicidality [suicidal ideation and behavior] in antidepressant users (4%) compared to the placebo users (2%) during the first few months of treatment.  FDA approved only Prozac (fluoxetine), considered as the safest SSRI, for MDD [major depressive disorder] in pediatric patients; FDA approved Prozac, Zoloft (sertraline), Luvox (fluvoxamine), and Anafranil (clomipromine) for OCD in pediatric patients.
     
    Systemic reviews have shown differing conclusions about the increased risk for suicidality.  This particular meta-analysis reviewed studies for the same nine antidepressants that FDA reviewed.  It encompassed more than 48,000 depressed patients, including 77 subjects who committed suicide while participating in the studies.  Unlike FDA study, this review analyzed the actual rate of suicide that was successful, instead of suicidality.  As result, the investigators did not find statistically significant difference among the subjects on placebo, SSRI, or other types of antidepressant. 
     
    Upon reviewing available data, the American Academy of Child and Adolescent Psychiatry (AACAP) and the American College of Neuropsychopharmacology have concluded that the benefits of SSRIs for treating depression in youth outweigh the risk for suicide.  They also point out that the depressed children and teenagers are at inherent risk of suicide.  In addition, TCAs are not effective in children and adolescents; cognitive behavioral therapy hasn't shown to be effective in children with depression, leaving SSRIs as the only option.  AACAP also warns about the risk of not treating depression in children.
     
    This author in NEJM also reminds us about weighing benefit vs. risk of therapeutics.  Although FDA's analysis showed the risk of suicidality with SSRI use in children, the risk is small.  Banning pharmacologic treatment for pediatric depression due to the fear of increasing suicidality may take us back 25 years--when there was no pharmacological help for pediatric patients with depression and when the pediatric population suicide rate was higher.


    I’m going through my “change”?

    Menopause is a natural part of a woman's life cycle.  However, women often experience a decreased quality of life from the symptoms that accompany menopause.  Some women are turning to hormone replacement therapy to relieve their symptoms.  Other women choose to use "natural" products to combat the symptoms of menopause.  This meta-analysis reviewed 29 randomized controlled studies of commonly used alternative therapies for treatment of menopausal symptoms.

    The meta-analysis showed that only soy products, black cohosh, and progesterone cream have shown promise for treating hot flashes.  Acupuncture, Vitamin E, and wild yam had no effect on decreasing the severity or frequency of hot flashes.

     

    What are the other benefits of soy?  This double-blind placebo study had three treatment groups.  Post menopausal women receiving isoflavone rich soy, isoflavone poor soy, and placebo.  The study was conducted for 24 weeks.  It found that 84 g/day of Isoflavone soy products decreased lumbar bone loss.  While the placebo group and Isoflavone poor soy products showed an increase in bone loss.

     

    Exercise is great for everything right?  Must be great for menopause too.

    This study compared post-menopausal women who exercise for 26 months and a placebo group which was sedentary.  Both groups were supplemented with calcium and cholecalciferol.  The exercising group worked out four times per week.  At the end of the study the group that exercised had less bone loss, less back pain, and a better lipid profile.

    There is a very small body of evidence concerning non-pharmological treatment and menopause.  Hopefully, more research will be conducted to determine the benefits of some commonly used practices to alleviate the symptoms of menopause.

    Vitamin E-can it be doing more harm than good?

    Vitamin E- can it be doing more harm than good? WHAT~? Isn't vitamin E one of those things that you should be trying to get a lot more of, you know like those fish oils pills because their so good for you and everything? I know, I thought the same thing until recently when I happened to be flipping through random channels and came across an interesting story (video clip) on CNN.

    Apparently, a recent study out of John Hopkins University (re-analyzed 19 studies of vitamin E and health between 1993-2004) found that people who took 200 or more international units (UI) of vitamin E a day died at a higher rate than those that were taking the placebo. Although the authors acknowledged that the people involved in the trial were aged 60 and older and had comorbid conditions, the results warranted not only further investigation, but also warning the public against taking too many supplemental vitamin E pills.

    So what should we tell are patients that are taking supplemental vitamin E? As for now, there isn't enough research that has been done on younger patients to tell them to stop taking supplements, however the general consensus has been that the amount of vitamin E in a multivitamin (10-30 UI) is sufficient for most people.  However, for those that are looking for more vitamin E, you can always recommend them to supplement in natural ways by eating more nuts, green leafy vegetables and vegetable oils all of which are high in vitamin E.


    Relax...it's good for your heart.

    A running theme throughout these four weeks in Family Practice has been patients coming in complaining of stress along with one thing or another be it hypertension, hyperlipidemia, headaches, or diabetes. Unfortunately, more often than not the stress aspect of the complaint is ignored or deferred to a therapist and the more "concerning" conditions are addressed. I have heard so many times that stress does indeed play a role in pathology, particularly as a risk factor for coronary heart disease, but I wanted to know - what are the facts?  

    In an article in the European Heart Journal, a study was conducted to determine whether chronic psychosocial stress predicts long-term cardiovascular morbidity and mortality. The study took place between 1974 and 1980 and involved a total of 13,609 participants with an average age of 45 years old. Individuals in the study were required to complete a questionnaire determining self-reported chronic stress. Three test groups were then created 0 (low stress), 1 (medium stress), 2 (high stress). All subjects were followed   in local and national registries over 21 years for total mortality, cause-specific mortality, nonfatal ischemic heart disease, and nonfatal stroke. The study concluded that self-reported chronic stress is indeed an independent risk factor for cardiovascular disease in middle-aged men. This was particularly so for fatal stroke. Surprising for women, there was no significant relationship between chronic stress and cardio-vascular disease.

    In yet another article, the INTERHEART study investigated patients with a history of an acute myocardial infarction against a group of controls matched by age and sex.The purpose of the study was to determine the effect of psychosocial stressors on myocardial infarctions in different populations grouped by age, sex, geographic region and ethnic origin. A case control study was used with 11,119 patients with a first myocardial infarction and 13,648 age-matched and sex matched controls from countries including Asia, Europe, the Middle East, Africa, Australia, and North and South America. Psychosocial stressors were determined via a questionnaire of four questions regarding home and work environments, financial stability, and major life events within the past year. The effect of stress as in increased risk factor for myocardial infarction was determined to be independent of socioeconomic status and smoking, and was consistent across different age groups, geographic regions, and in men and women. Furthermore, it was shown to be a significant independent factor after adjusting for other cardiovascular risk factors. The article concluded that psychosocial stressors are indeed correlated with increased risk of myocardial infarction and recommended that in light of this unequivocal data, attempts be made to modify these factors.

    Apparently, public opinion of the deleterious effect of stress appears to be supported by the literature - particularly the effect of stress as an independent risk factor for cardio-vascular disease. So, the next time a patient comes in complaining of stress, it should raise within us a red flag to investigate further and attempt to offer avenues for reduction and management.

    bextra heads up

    A little advice... get rid of your Pfizer stocks.  A study presented this past Tuesday at an American Heart Association meeting found that the treatment group taking bextra had approximately a 2.2 fold higher risk for heart attacks and strokes compared to the control group taking a placebo.  The study was based on 7,771 pts.  This study has not yet been published, but has been reported on several popular newspapers, such as this NY Times article.

    Last month, Pfizer conceded that Bextra was associated with an increased risk of thromboembolic events in CABG pts, but stated that this risk does not extend to other pts.  In response to the recent NY Times article, Pfizer released a November 10 statement that these findings are unsubstantiated and emphasized that since these results have not been published, it has not been subject to independent scientific review.  Pfizer states that current published evidence supports that Bextra is not associated with an increase in cardiovascular thromboembolic events for pts being treated for osteoarthritis and rheumatoid arthritis.

    Regardless of whether this is evidence based medicine or not, there's going to be a few pts that get a hold of this info and will be asking you whether it's safe to take their bextra. What are you going to tell them?


    Banning (restricting) cell phone usage in the hospital?!!!

    Cell phone use is growing worldwide.   Mobile phones are a source of irritation for some, but undeniably useful for many.  But go into many hospitals (especially EDs) and you'll often find that cell phone usage is banned or restricted to certain areas.  But since many patients and medical personnel like "connected" at all times and this can be an inconvenience.   Prompted by a discussion I had with a resident, I decided to investigate and here are some things I found:    

    1. Mobile phones can interfere with medical equipment. 
        
    2. The two-way radios used by emergency-service personnel and hospital transport aides (porters) are a big source of interference.
       
    3. Other sources of radiofrequency (RF) radiation (for example, digital TV broadcasts and other medical equipment) have also caused interference with medical devices.
       
    4. Many (most?) hospitals ban mobile phones, but the bans are often very poorly enforced on visitors or on staff.

    So, what the evidence for banning/restricting cell phone usage in hospitals?  Recently, a group studied if cell phones interferred with the the operation of mechanical ventilators.  Of the fourteen mechanical ventilators evaluated, 6 malfunctioned if a cell phone at maximum power was place at or less than 15 cm from the machine.  Of the 6, only one produced malfunction that could have been life-threatening.  Based on their results and other literature, the authors concluded cell phone usage in ICUs was permittable if kept at or greater than 3 feet from all medical devices.

    Searching for a more comprehensive study, I found an article in the British Medical Journal that conducted a systematic review of studies on clinically relevant digital mobile phone electromagnetic interference with medical equipment using articles published between 1966 and 2004.  They concluded that at least 4% of devices tested were susceptible to clinically relevent electromagnetic interference (EMI) secondary to mobile phones.  They also found that all studies recommended some type of restriction of mobile phone use in hospitals, with use greater than 1 m from medical equipment and restrictions in clinical areas being the most common.

    In conclusion, the evidence does justify restricting, but not necessarily banning cell phone usage in hospitals since problems can arise if phones are used too close to medical equipment.  By restriction rather than banning cell phones, this will hopefully increase compliance.  These restrictions need to be enforced diligently.  But as new medical equipment is being designed, hopefully manufactures can make modifications so that this will not be an issue in the future.

    Treatment of Attention-Deficit/Hyperactivity Disorder

    Background: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common disorders diagnosed in children and adolescents. The American Psychiatric Association (APA) describes the essential feature as "a persistent pattern of inattention and/or hyperactivity-impulsivity that is more frequent and severe than is typically observed in individuals at a comparable level of development." According to the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV), the prevalence of ADHD in school-age children is 3 to 5 percent. ADHD has been associated with impaired academic achievement, rejection by peers, and family resentment and antagonism. The rich terminology may reflect the broad spectrum and the high frequency with which it is described with other comorbid conditions.

    Questions: What is the treatment of Attention-Deficit/Hyperactivity Disorder?


    Discussion: Attention-deficit/hyperactivity disorder is one of the more common chronic conditions of childhood. Studies using parent reports indicate persistence of ADHD of 60% to 80% into adolescence.  Given the high prevalence of ADHD among school-aged children (4% to 12%), primary care clinicians will encounter children with ADHD in their practices regularly and should have a strategy for diagnosis and long-term management of this condition. The primary care of children with ADHD includes attention to the main principles of care for children with any chronic condition, such as

    • Providing information about the condition
    • Updating and monitoring family knowledge and understanding on a periodic basis
    • Counseling about family response to the condition
    • Developmentally appropriate education of the child about ADHD, with updates as the child grows
    • Availability to answer family questions
    • Ensuring coordination of health and other services
    • Helping families set specific goals in areas related to the child's condition and its effects on daily activities
    • Linking families with other families with children who have similar chronic conditions as needed and available
    The core symptoms of ADHD (ie, inattention, impulsivity, hyperactivity) can result in multiple areas of dysfunction relating to a child's performance in the home, school, or community. The primary goal of treatment should be to maximize function. Desired results include
    • improvements in relationships with parents, siblings, teachers, and peers
    • decreased disruptive behaviors
    • improved academic performance, particularly in volume of work, efficiency, completion, and accuracy
    • increased independence in self-care or homework
    • improved self-esteem
    • enhanced safety in the community, such as in crossing streets or riding bicycles. Target outcomes should follow from the key symptoms the child manifests and the specific impairments these symptoms cause.
    The process of developing target outcomes requires input from parents, children, and teachers, as well as other school personnel where available and appropriate.  They should agree on at least 3 to 6 key targets and desired changes as prerequisites to constructing the treatment plan. The goals should be realistic, attainable, and measurable. The methods of treatment and of monitoring change will vary as a function of the target outcomes.
    The clinician should develop a comprehensive management plan focused on the target outcomes. For most children, stimulant medication is highly effective in the management of the core symptoms of ADHD. For many children, behavioral interventions are valuable as primary treatment or as an adjunct in the management of ADHD, based on the nature of coexisting conditions, specific target outcomes, and family circumstances. The most powerful effects are found on measures of observable social and classroom behaviors and on core symptoms of attention, hyperactivity, and impulsivity. The effects on intelligence and achievement tests are more modest.

    Effective Behavioral Techniques for Children With Attention-Deficit/Hyperactivity Disorder
    Technique
    Description
    Example
    Positive reinforcement
    Providing rewards or privileges contingent on the child's performance.
    Child completes an assignment and is permitted to play on the computer.
    Time-out
    Removing access to positive reinforcement contingent on performance of unwanted or problem behavior.
    Child hits sibling impulsively and is required to sit for 5 minutes in the corner of the room.
    Response cost
    Withdrawing rewards or privileges contingent on the performance of unwanted or problem behavior.
    Child loses free time privileges for not completing homework.
    Token economy
    Combining positive reinforcement and response cost. The child earns rewards and privileges contingent on performing desired behaviors and loses the rewards and privileges based on undesirable behavior.
    Child earns stars for completing assignments and loses stars for getting out of seat. The child cashes in the sum of stars at the end of the week for a prize.
    Conclusion: Families must manage the treatment of ADHD on an ongoing basis. Treatment need to include long-term management plan. It is important to set behavior goals, improvement in school work. Establish follow-up to adjust the medication, that would make changes that affect behavior at school and at home. At every visit check the child's progress with the target outcomes. For most children, stimulant medications are a safe and effective way to relieve ADHD symptoms. Behavior therapy should focuse on changing the child's environment to help improve behavior. Educating the parents about the disease and how to deal with the child behavior can give parents specific skills to deal with ADHD behaviors in a positive way. All involved need to understand what ADHD is. Treatment works best when doctors, parents, teachers, caregivers, other health care professionals, and the child work together.


    Neurontin for the nerves

    During the past few weeks I have seen my preceptor prescribing neurontin for numerous patients suffering from diabetic neuropathy.  I didn't know what exactly the drug is or how it works, so I looked into it and here is what I found.

    Neurontin or Gabapentin (a product of Pfizer introduced in 1983)was designed to look like the inhibitory neurotransmitter GABA. Interestingly, the medication does not work by directly binding to the GABA receptors in the brain. Rather, the medication appears to work by raising GABA levels by some effect on a GABA transporter protein. It also decreases the activity of voltage-gated calcium channels via binding to a secondary protein. This effect occurs in only some of the neurons depending on additional cofactors being present (mechanism not clearly understood). It is therefore possible that it, in some way, targets abnormally acting neurons and not the normal neurons.

    To my surprise Neurontin is only FDA approved for treatment of new onset partial seizures and post herpatic neuralgia.  However it has developed a list of off-label indications such as diabetic neuropathy, migranes, restless leg syndrome, and fibromyalgia.

    I found a study that looked at pain relief in type 2 diabetes mellitus patients with neuropathic pain treated with gabapentin at daily dose 2400 mg. After six weeks of gabapentin treatment in 2400 mg daily dose a significant pain reduction was observed. 

    Neurontin is considered a very safe drug with few side effects.  The most common side effect being drowsiness and weight gain.  Patients can also experience unsteadiness on high doses.

    This year Pfizer introduced Lyrica (pregabalin) as a successor to Neurontin (facing generic competition).  It has been approved by the FDA in September 2004 for three indications: neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, and as adjunctive therapy in the treatment of partial seizures in adults.  Pfizer also wanted it approved for generalized anxiety, but was denied by the FDA.

    Lyrica and Neurontin have the same mechanism of action, however, Lurica achieves efficacy at lower doses which leads to fewer side effects.


    Vaccine for HPV 16/18
     

    Hey guys & gals, a new vaccine for HPV may soon be on the horizon!  According to a phase 2 trial published in The Lancet (Nov. 13, 2004), a virus-like particle vaccine prevents both infection as well as cell abnormalities (including precancerous & cancerous lesions) due to HPV 16 & 18.  If approved, this vaccine could prevent up to 70% of cervical cancers worldwide! 

    The article describes a Phase II study of 1,113 women (mean age = 20) who recieved 3 injections, 6 months apart, of the vaccine.  They were followed up over 27 mo and tested for HPV. 

    The vaccine was 91.6% effective against incident infection (95% confidence interval [CI], 64.5 - 98.0).

    It was 100% effective against persistent infection (95% CI, 47.0 - 100.0).

    The vaccine is highly immunogenic.  Women who finished the series had up to 100 times the level of antibody protection for HPV-16 than they would if naturally exposed to the virus.  Levels against HPV-18 were up to 80 times greater.  Even at 18 mo, titers were 10 and 16 times greater than natural for HPV 16 & 18, respectively.

    Although no adverse reactions from the vaccine were studied, we need to know more about the long-term immunization.  Does the immunity last?  Only time (and research) will tell.   


    Comment Commentary!
    Don't forget that part of this learning experience incorporates reading and commenting on the posts.  When you post this week, take a few minutes to look thru and throw in your two cents worth!


    AOM - Abx for no one?

    By now I'm sure everyone has seen their fair share of cases of AOM.  Well, every single time I've heard the same speech from my physician about the parent having the power to treat the illness by doing nothing at all...just waiting and watching and treating the child's pain.  Sometimes the parents are amenable to this option and other times they just want the antibiotic.  Which type of parent is right?

     

    Well, several studies have been done on this subject.  One study (which I was not able to link to) found demonstrated a lack of correlation between antibiotic use and therapeutic benefit.  It seems that is the direction that the research shows, but a true test is how the parents and patients in the United States are reacting to it, and what physicians are doing in their treatment plans.

     

    A great study used claims data for dispensed medications and physician visit records from 1996-2000 and it seems that word is catching on. There was a significant describe in the prescribing of antibiotics, especially for otitis media.

     

    However, another study demonstrated some of the problems with AOM: overdiagnosis and subtherapeutic dosing of antibiotics being two of the most prevalent.  Compliance with the CDC guidelines for treatment was found to be 38% by chart audit, and 41% by self report.  Hey, at least the docs were honest, right?

     

    The final study I looked at, investigated a possible solution: SNAPs. Safety Net Antibiotic Prescriptions have been used in other countries with success.  This study set out to determine whether or not it could catch on in the US.  This Ohio Valley study found that of the 175 children who completed the study, only 31% had filled their antibiotic prescription.  This demonstrates a willingness on the part of parents to treat with pain medication only, and might be an option for the future in the United States.

     

     It's a healthy thing to look for solutions, rather than just trying to find the faults with everything.  After all, that's how things get better.

    GERD

    While not the most exotic topic, Gastroesophageal Reflux Disease is very common.  It is a rare day that I don't see at least 4 patients with GERD on their list of diagnoses.  Of course, this does not diminish the importance of treating it aggressively, given the serious morbidities involved with ignoring the problem.  Although GERD was previously treated with H2 blockers, it is generally accepted that Proton Pump Inhibitors (PPIs) are the superior treatment.  Pharmaceutical interests know this very well and therefore there are a number of PPIs on the market.  Obviously, the question for us is which one to choose for our patients. Efficacy is a concern, as well as, possible interactions with other medications.

     

    • This review compares some of the more popular PPIs and states that Rabeprazole (Aciphex) may have a greater potency than Omeprazole (Prilosec).  Also, Lansoprazole (Prevacid) and Aciphex provide earlier and better symptom relief than the other PPIs in some studies.
    • This study reiterates the idea that PPIs are superior to H2 blockers.  In addition, it concludes the newer PPIs were of similar efficacy to omeprazole in terms of heartburn control, healing rates, and relapse rates.
    • This study does have a favorite however.  Aciphex was the most potent acid inhibitor of all the proton pump inhibitors tested during the first day of dosing, according to its authors.
    • With respect to polypharmacy, this study investigated the effects of common PPIs on the P450 enzymes.  Prevacid and Pantoprazole (Protonix) are potent inhibitors, in vitro, of CYP2C19 and CYP2C9, respectively.  Also, Aciphex showed lower inhibition, however its thioether analog showed potent inhibiton on the P450 enzymes studied.

     

    Most of the PPIs are quite similar in their efficacy and drug interaction profiles and therefore, it is probably safe to treat GERD with any of them.  Other important factors to consider are the cost of each and whether a particular patient's insurance plan covers the agent you wish to prescribe.

    Who should be screened for gestational diabetes mellitus (GDM)?

    I saw many pregnant women at the clinic who had oral glucose tolerance test (OTT).  Because many of them seemed to be healthy, I wondered about the criteria for screening for GDM.  If there were criteria, what were they?  Do ALL pregnant women go through GTT?  My research showed the following. 

    The American Diabetes Association (ADA) and The American College of Obstetricians (ACOG) recommend that screening should be limited to women with high risks.  This study screened over 3000 pregnant women.  The investigators categorized half of the subjects according to their age, BMI, and race and analyzed the data in conjunction with their plasma glucose levels; based on that population, they came up with strategies to screen women more selectively.  When they used the new strategies on the other half of the subjects, they detected about 35% reduction in the number of screening test performed and detected about 82% sensitivey compared to 78% sensitivity through usual care.
     
    The American College of Obstetricians use the following criteria for low-risk women:
                    Age younger than 25
                    Not Hispanic, African, Native American, South or East Asian, Pacific Islander
                    BMI less than or equal to 25
                    No history of abnormal glucose tolerance
                    No history of adverse pregnancy outcomes often associated with GDM
                    No first degree relatives with DM
                    Women's own birth weight was normal (greater than or equal to 6 lb ; less than or equal to 9 lb.)
     
    However, a group of investigators in Australia studied pregnancy outcomes (ex. emergency C-section, SGA neonates, etc.)  in both low-risk and high-risk groups and found the pregnancy outcomes to be similar.  They also found 2.8% prevalence rate of GDM in low risk women and urged that the low-risk women should also be screened for GDM. [universal screening]

    Ironically, the U.S. Preventive Services Task Force (USPSTF) concludes that the evidence is insufficient to recommend for OR against routine screening for GDM.  They found no sufficient evidence that screening for GDM substantially reduces important adverse effects such as cesarean delivery and neonatal injury. However, they found good evidence that screening with diet and insulin therapy can reduce the incidence of fetal macrosomia in women with GDM. 
     
    Although there seems to be mixed messages about GDM screening, I personally agree with universal screening.  Being aware of GDM status may motivate many pregnant women to exercise and get a good prenatal care.  Since macrosomia is associated with other risks, it is important to reduce the incidence.   

    Besides, how many people you know actually fall into the ‘low risk' group defined by ACOG to avoid the screening?


    Juice Plus, doe is it work???

    This week we had an obese female ( 300+ lbs., 5'5") come in for a follow-up on her blood work. She had a history of hyperlipidemia (high cholesterol, high LDL, and triglycerides). As I was going over her recent blood work with her, I was impressed to see that everything was within normal limits. Her triglycerides had decreased by 30, her total cholesterol was down by 20, and her LDL had also decreased. I told her it looks like she's been doing very well over the past year; she must be eating healthy and exercising. Then she told me she's actually been eating worse. I looked through her chart, and she was right; she had gained about ten pounds over the year. I kept telling her she must have done something because her blood work numbers were so impressive. And she swore that she wasn't exercising more, and she was eating more junk. I didn't have an explanation for her, and neither did my preceptor. Then she told us the only thing different that she's been doing is taking Juice Plus.

    I had no idea what Juice Plus was. A representative from the company had actually come to our Family Practice office months ago and gave a whole talk on it. The company is similar to organizations like Amway. The customers sell the product to other people, and the more people you have on your list the more you make. Our patient wasn't selling it, she had just gotten the Juice Plus from a friend.

    Juice Plus is a condensation of fruits and vegetables in a pill form, and claims to be more bioavailable then regular multivitamins. They claim it's the next best thing to eating raw fruits and vegetables. On the Juice Plus website, you can find more information on how it's made, and the science behind it. There are also scientific articles on bioavailability, positive affect on the immune system, and decrease in DNA damage on the website. Keep in mind these studies are sponsored be Juice Plus, and the sample size in some of the studies were 15, so the validity is in question. There were was another double-blind, placebo controlled study done by the University of Sydney that found a fruit/vegetable concentrate like Juice Plus to reduce homocysteine levels, and increase antioxidant level, and thus in the absence of diet modification helped in reducing the risk of coronary artery disease. Again the research was supported financially by juice plus, and there was no comparison to how this was different than a multivitamin. There is a follow-up article to this study, which points out it's major flaws. One really interesting point this follow-up article brings up is that the Juice Plus pills are infused with pure ß-carotene, ascorbic acid, vitamin E and folic acid, in addition to the concentrated fruits and vegetables. In the study they found only plasma ß-carotene to increase significantly not lycopene or other nutrients found in the fruits and vegetable. So it seems the nutrients they infused into the pills are bioavailable not the nutrients from the fruits and vegetables. This study shows that supplementation with B-vitamins also increases homocysteine. This is an in depth review looking at multivitamins and reducing the risk of cardiovascular disease. They found there was an association between supplemental vitamins and lower risk of cardiovascular disease.

    I didn't find any studies that directly compared Juice Plus with an ordinary multivitamin. The benefits found with Juice Plus are the same benefits that have also been associated with vitamin use. A study that compared the two would help to establish whether Juice Plus is actually better. It may be, but there isn't any data to back that up. Even though the blood work from our patient was impressive, I would still want some more research before I was convinced of the great benefit of Juice Plus.

    On the Juice Plus website they state Juice Plus really is "the next best thing to eating fresh, raw fruits and vegetables". If that's the case, I would just recommend eating fresh fruits and vegetables, it's cheaper and you don't have to worry if you're really getting what they say you are.


    Stop touching those testicles!!!

    That's right, I order you to stop.  I'm sure all the guys know what I'm talking about when I say that we too have to undergo some uncomfortable exams while going to the doctor's office.  The thought of the 74 year old creepy high school team doctor telling me to drop my pants so he can do a genital exam will be forever burned into my memory.  However, that dreaded act was unnecessary.  After going to a family medicine conference last week we learned that current recommendations are NOT to perform male genital exams.

    Screening for testicular cancer has been part of office visits for a long time, however there is no evidence to support doing so.  This study yielded no support for routine testicular cancer screening as there was no found decrease in morbidity and mortality when doing so.  Now both us as healthcare providers and our patients can forego this often uncomfortable part of the exam.  So this is good for everyone, except for poor old Dr. Feerstein, who I and everyone else on my team swear took pleasure in it.


    Being "tired" might be a disease!

    Chronic fatigue syndrome, also known as myalgic encephalomyelitis, is an incapacitating illness that is estimated to affect between 400,000 and 800,000 Americans. It is a disease defined by symptoms and disability, with no known pathophysiology or confirmatory laboratory values. It seems that some physicians don't think it exists, while others are firm believers that it's a real entity. I've noticed different reactions to chronic fatigue syndrome from physicians and wanted to know what research was available on the subject.    

     

    Obviously, this disease is troubling to physicians because of it's indistinct nature, as well as it's economic impact on the US healthcare system.  One study estimated it's impact to be 9.1 billion dollars.  Another study recognized the difficulty of the diagnosis and tried to come up with standard measures of the disease.  It was very interesting that one study delved into whether or not physicians actually believed CFS as a diagnosis.  The study went on to recognize perception as a barrier in the treatment of the disorder.

     

    Another study found several differences in their patient population with CFS.  Increased body temperature, pulse, and evidence of deconditioning were all apparent.  In any event, with respect to CFS, I would caution the health care community to take this entity seriously and to push for further research into it's etiology.  To simply exclude CFS as a possibility because of a disbelief of its existence is not fair to one's patients or profession.


    Black Cohosh

    In the past several weeks my preceptor and I encountered many women who are going through menopause and have many complaints regaurding their menopause symptoms.

    Menopause is diagnosed one year after the last menses and is characterized by a continuation of vasomotor symptoms and by urogenital symptoms such as vaginal dryness and dyspareunia. However 50-80% of women begin to experience vasomotor symptoms (hot flashes) several years before menopause.  Traditionally these symptoms have been treated with hormone replacement therapy.  However HRT has been the subject of much controversy recently and it can increase the risk of breast cancer.  Many women are not comfortable using HRT and yet need relief from their symptoms. 

    My preceptor offered black cohosh as a way to releive some of these symptoms.  So I wanted to look into it and see how it helps symptoms.

    Black Cohosh is a North American forest plant which can grow up to 8 feet tall.The American Indians used to boil the root and drink it for a variety of diseases of women. Hence the name Squaw root. The active ingredient is 24-deoxyacteine.  Black cohosh is ground or extracted and taken in tablet, capsule, or liquid form. The best-known and most-studied brand is Remifemin, manufactured in Switzerland.

     Black Cohosh is fairly well studied in Germany, where it is used to treat hot flashes. Experiments have shown that the herb has substances that bind to estrogen receptors in animal models and lower LH ( a hormone which is elevated in menopause ) in both animals and humans.The herb was an official drug in the U.S. Pharmacopoeia from 1820 to 1926.

    A website by Association of Women for the Advancement of Research and Education is designed to introduce alternative therapies for menopausal symptoms.  It reports Clinical studies have shown extracts of black cohosh to relieve not only hot flashes but also depression and vaginal atrophy. In addition to these vascular effects, black cohosh reduces LH levels; thus the plant has a significant estrogenic effect.  The use of 10-15 drops once or twice a day for several months significantly reduces LH but not FSH.

    Black cohosh is generally considered safe to use short term, however there is very little evidence about the safety of its long term use.  Counterindications include:

    • Pregnancy (promotes menstruation) 
    • Chronic medical conditions
    • Breast cancer
    • High risk of cancer

    Black cohosh is priced between $8.99 and $12.99.


    I can't sleep at night!

    It seems that more and more patients today suffer from insomnia.  Insomnia can have a very adverse effect on one's life.  It affects ones mood, work, and relationships.  It has also been found that patients with chronic insomnia have higher rates of psychiatric and medical illnesses.  Insomnia is also an important risk factor in the development of depression.

    There are a lot of treatments to treat insomnia and many alternative treatments to benzodiazepenes.  The most commonly prescribed therapy for insomnia at my clinic is Ambien (zolpidem).  Zolpidem has proven to be a very effective treatment for insomnia.  However, there is also a concern over the addictive effects of zolpidem when used over a long period of time.  Research has shown that zolpidem is a relatively safe drug for patients to use.  However, since zolpidem is a psychotropic drug, there is an increased risk of abuse among patients with a history of abuse or dependence. 

    There are also alternative methods to treating insomnia.  In particular, having a good "sleep hygiene" has been found to reduce insomnia.  Sleep hygiene includes having a regular bed time, abstaining from caffeine and alcohol in the afternoon and/or evening, avoiding cigarette smoking, and exercising regularly.   


    Connection between Galactosemia and Premature Ovarian Failure

    A few days ago, I met a very kind 38-year-old woman who came to the office to have cerumen flushed out of her ears, as this was impairing her ability to hear. She was accompanied by her mother. This patient has galactosemia, which is a rare autosomal recessive disorder in which there exists impairment in galactose 1-phosphate uridyltransferase (GALT) metabolism. (There is another interesting more abbreviated factsheet on the disease for anyone interested.) The patient has mild mental retardation, has a pronounced speech impediment and is overweight. She also states that she has trouble maintaining her balance when she walks. During the initial part of the visit, my preceptor conveyed to the mother that in recent blood tests that had been done, her daughter's cholesterol level was found to be high. She went on to explain that since the patient was post-menopausal, was exposed to second-hand tobacco smoke and because she has a family history of high cholesterol (her mother is also being treated for high cholesterol), she was at increased risk for early cardiovascular disease and that it was advisable to have her start taking a statin. What struck me about this was that the patient had not had menses for several months already (after having a normal menstruation in earlier years) and yet she was only 38!

    I did not recall from past reading that there was a connection between premature ovarian failure (POF) and galactosemia. As galactosemia is a disease that we don't often encounter, I thought it might be interesting to do some reading on it... Among the literature that I found, there was an article that delineated the differences between premature ovarian failure and premature menopause. (I also was not aware of this distinction.)

    Finally, I went in search of how galactose toxicity might cause problems in the ovary which would lead to cessation of menses at an early age, being that normal menopause occurs on average around 50 years of age and perimenopause usually ocurs after age 40. I found this basic science study done using rats as a model for POF by Bandyopadhyay et. al. "The causal link between galactosemia and POF is not definitely known" say the authors. "There are suggestions, however, that premature depletion of ovarian follicular reserve is due to toxic effects of galactose and its metabolites." The authors also found that exposure in-utero to high galactose, which they mimicked by feeding pregnant rats large amounts of galactose so as to overpower the normal capacity of the animal to metabolize the sugar, had an adverse effect on oogonial migration, resulting in a low initial set of germ cells in the developing ovaries of the fetus. They also discovered in their research that the galactose-exposed group of rats had more atretic secondary follicles than the control group. They therefore believe that "an increased rate of atresia as well as a deficient initial ovarian pool of germ cells are implicated in the process of premature depletion of ovarian follicles under galactose toxicity." The scientists' main drive for carrying out this research was to find a suitable animal model to study this correlation due to the obvious ethical limitations present in carrying out in-depth research on humans.

    Finally, since nearly all the articles I read quoted this guy Guerrero, I've linked his article too. For info on other diseases associated with POF, see the following.


    Can an aspirin a day keep cardiac disease away?
    A common theme running through the clinic this week was the overwhelming use of aspirin by patients in an attempt to prevent heart disease. In the United States, cardiovascular disease is the number one cause of morbidity and mortality and as such its prevention should receive high priority within the medical community. So, can aspirin really help? 

    An article written in the Journal of Family Practice, reviewed the five key studies looking at the effect of aspirin on the prevention of cardiovascular disease. In total, the studies evaluated over 50,000 patients with various degrees of cardiovascular risk. The studies concluded that for most patients aspirin therapy is effective at preventing acute cardiac episodes. The ideal aspirin dosage was not determined, however, they did find that lower doses (75-81mg/d) which have fewer side effects (notable bleeding) were as effective as higher doses. The studies concluded that aspirin use should be recommended to all patients with coronary artery disease or at high risk of developing it. One shortcoming of these studies was that although women did participate in two of the studies, they were excluded from the other three and therefore, the information on aspirin benefit is less definitive for them as a group.

    Another article in the Archives of Internal Medicine also analyzed five significant studies associating aspirin use with the reduction of cardiovascular disease. Again, a total of about 50,000 participants were evaluated and aspirin was associated with a 32% reduction in the risk for a first myocardial infarction and a 15% reduction in other cardiovascular events. The article provided strong support for a 1988 Physician's Health Study (i could only locate the abstract - sorry) - a randomized, double-blind, placebo-controlled trial of 22,071 men terminated early due to overwhelming evidence demonstrating that aspirin use resulted in a 44% reduction in the risk of a first myocardial infarction.   

    In summary, aspirin appears to be an inexpensive, easily accessible, and promising method of reducing cardiovascular disease. Although aspirin therapy is not without its side-effects particularly gastrointestinal bleeding, studies have shown that especially in patients already diagnosed with CAD or at high risk for it, the benefits certainly outweigh the risks.


    balance of addiction/pain

    I've had a difficult time knowing when to prescribe drugs like loratab and fentanyl for pain management (its a problem for most FP docs).  Everyday I have someone coming in asking for continued, increased, or new drugs to manage their pain. 

    Every one them has a different story and a different background;  There is the recovering heroin addict, the middle aged woman in chronic undiagnosed pain, the disabled 40 yo male whom is disabled and underwent a suspect neck surgery five months ago with no accompanied relief in pain, or the man with trigeminal neurolgia of 3 years who insists on more loratab.

    I am certain that all of these people are in some type of pain, but for the lack of a pain'o'rometer the physician is left to distinguish what is treatable and what is not.  I just assume give everyone what they want...but addiction, pseudoaddiction, physical dependence, and tolerance are all horrible just like the undertreatment of pain.    What I found was that current literature stresses failure to treat pain, far outwieghs the consequence of treating fictional pain.

    There is also a movement that the use of opiods should be used in the treatment of chronic nonmalignant pain if function and symptomatology are improved with it. This article furthered my belief that even with constant opioid treatement  the patient's overall severity of pain and symptoms will remain high. 

    So, in conclusion, guidelines are used in cases of specific diseases and syndromes but not such broad cases as chronic non-malignant pain.  When dealing with such persons there is not any specific methodology or precise guidelines, just common sense and your intuition. Treat when in doubt, just exhaust all efforts before you use opioids and other addictive pain relievers.


    Correlation between irritable bowl syndrome (IBS) and abuse?

    This past week a 33-year-old woman came into the clinic for a normal check-up.  As I flipped through her chart, I noticed her past medical history was significant for irritable bowel syndrome (IBS).  I thought I had read that IBS can be associated with abuse and wondered if it would be helpful to inquire about abuse.  But the resident I was working with did not know of any such correlation.  I began to doubt myself—therefore, it was time to search the literature! 

    IBS is a common functional disorder, occurring 10-20% of the population.  It is characterized by chronic abdominal pain that is associated with defecation or a change in the frequency or appearance of stool.  Possible etiologies for IBS include a recent episode of bacterial gastroenteritis, female gender and lower household income.  The diagnosis of IBS is made by obtaining a history of symptoms compatible with IBS and by excluding other conditions.  The physical examination is in patients wit IBS is unremarkable.  For most case, treatment involves learning to reduce stress and making changes in lifestyle and diet.  For more severe cases, pharmacological therapies can be employed.   

    According an article on ABC online, yes, there was a correlation between emotional abuse and IBS.  Based on a report published in Psychosomatic Medicine, the ABC article concluded that patients with IBS had higher mesures of emotional abuse.  Unforunately, the study in Psychosomatic Medicine only used a total of 50 subjects (both IBS and subjects) and had used patients with inflammatory bowel disease (IBD) as its control, making it an less-than-ideal study.    

    But where's the beef?  Wanting to more solid data, I turned to a scientific literature search.  One multicenter study compared the prevelance of sexual abuse in 196 patients with IBS to 507 control using a chi 2 test to analysize the date from anonymous questionnaires.  They found a significantly higher prevalence of sexual abuse (31.6%) among IBS patients than controls (7.6%).  Additionally, IBS patients also reported more physical abuse (14.7%) than controls (8.8%).

    But then on the other hand, another article also investigated the prevalence of previous abuse experience in patients with IBS.  But they found that there was NO significant difference between IBS patients and controls. 

    Therefore, the jury is still out whether there is a correlation between IBS and abuse.  But regardless, since questioning a patient about abuse does not cause them any harm, I think inquiring about abuse during an IBS work-up is not unreasonable and may help with treatment.


    treating nail fungus

    Onychomycosis or nail fungus affects about 2-8% of the population.  It is well established that oral treatment with terbinafine (Lamisil) is superior to other oral treatments (e.g. itraconazole and griseofulvin) and topical treatments (Penlac).  Actual reported cure rates of terbinafine range from 30-80%.  This wide range is due to inconsistent outcomes measured such as mycological cure, clinical cure, or both and also because of different study lengths that ranged from 1 year to almost 5 years.  Also, it should be added that several of these studies were funded by pharmaceutical companies.

    Since relapse rates are a major concern when treating onychomycosis, I assumed the study of the longest duration would be best suited to assess relapse.  This study showed that at 18 months 50% of the patients showed a complete cure (mycological and clinical cure) and after an average of 54 months only 35% had a complete cure.  This gives a relapse rate for complete cure of 30%.  Of those pts who relapsed and choose to undergo a second treatment of terbinafine, 72% ultimately achieved complete cure with two treatments of terbinafine.  It should be noted that this study followed pts to 54 months, which was the longest I could find.  From my preceptors' observations, it is very common for a fungus to recur 10-20 years after being symptom free.  

    Whether to treat onychomycosis is a difficult question for some.  Except for pts with advanced diabetes or vascular insufficiency, for most pts, it is completely a cosmetic issue with no systemic repercussions.  Since it is only a cosmetic problem, several insurance companies do not cover treatment.  It costs about $300/month for treatment and requires a minimum of 3 months of treatment for a total of about $1000.  If you want to reach that 72% success rate at five years you may eventually need two treatments which brings it to a grand total of $2000.  Lastly, although treatment is generally well tolerated, a risk for hepatotoxicity exists and LFTs should be monitored. 

    I for one would buy myself a good nail file and a pair of fine, Italian CLOSED-TOE shoes and pocket the rest of the 2G's.


    Here fishy, fishy, fishy!

    In one episode of Bert & Ernie, Ernie manages to get a whole boatload of fish by simply yelling, "HERE, FISHY FISHY FISHY!!!"  Of course, we now know that Ernie was collecting a wonderful source of Omega-3 fatty acids, which is probably why he and Bert are still alive and well and continue to entertain children on Sesame Street today.

    According to this excellent review article, fish oil supplements reduce all-cause mortality in CAD patients, lower risk for sudden death, lower serum triglyceride levels, lower blood pressure in HTN patients, and reduce the pain of arthritis. 

    Side effects noted: a fishy aftertaste, GI upset (nausea, bloating, belching), prolonged bleeding time, higher LDL-C and exposure to environmental contaminants (with certain species).


    The doses recommended by the American Heart Association vary depending on the condition you wish the fish oil to treat.  Hypertriglyceridemia is 2 to 4 g per day, while cardiac protection is 0.9 g of omega-3 fatty acids per day.  The later dose is provided by three 1-g capsules of most any commercial fish oil capsule, which contain 180 mg EPA and 120 mg DHA.


    The bottom line: fish oil is a safe complementary medication which reduces the risk of sudden death in patients with coronary heart disease.   That's why one of my preceptors suggests that her patients add fish oil to their diet, especially patients who are already interested in taking supplements such as Vitamin E to protect their heart. 


    "give me those pills"

    In the past couple of weeks have you guys seen antibiotics being prescribed when the patient might actually have a viral infection? Could this be because physicians feels that they have to give "something" in order to make the patient feel their visit was worthwhile? I was curious to find out what are patients' expectations when they go to the doctor for cold/cough treatment and if we are doing them injustice by over prescribing antibiotics just because we think they want some pills.

    In 1997 a study published in general practice assessed 1014 patient's views and expectations when visiting their doctor for lower respiratory symptoms. The study included a total of 76 physicians from all types of settings including suburban, inner city, and rural practices. The study looked at both the patients' and doctor's views about antibiotic prescription. During the patient's visit the doctors filled a data form that included information such as their certainty about whether or not to prescribe antibiotics and whether there were non-clinical factors influencing their decision to prescribe. The patients were given a sealed confidential questionnaire to be completed at home and sent back to the research office (78% return rate). The results showed that 75% of patients received antibiotics when only 20% had a definite indication for them. Interestingly, most patients thought their symptoms were caused by viruses that could be treated with antibiotics. Physicians reported that patient's pressure for medication influenced their decision to prescribe the antibiotics even though they felt it wasn't needed. Patients in the study whom did not receive antibiotics and wanted them expressed higher levels of dissatisfaction and reconsulted twice as much as the satisfied patients.

    I think this study clearly indicates the importance of patient education. If physicians had taken the time to explain the differences between viral and bacterial infections could the patients' expectations have been different? Could patients have been made to feel satisfied with their visit without having been prescribed medication that were not clinically warranted if they had been better educated?

    A more recent article published in Journal of General Internal Medicine in 2003 wanted to see if there has been a decline in patient's desire for antibiotic treatment for upper respiratory infections since the increased awareness of antibiotic-resistant bacteria. It was surprising to see that only 39% of the 310 patients wanted antibiotics. What patients did want was relief from symptoms and a diagnosis. The study also showed that physicians prescribed antibiotics to 46% of patients who wanted antibiotics vs. only 29% of patients who did not want antibiotics. This indicates that physicians are heavily influenced by patients to prescribe the abx even when it's not warranted.  Therefore, physicians should not make the mistake in assuming that patients want antibiotics when they and therefore feel compelled to prescribe it.

    I thought it would be interesting to see if parents had different expectations to get antibiotics when it came to treating their children. This was a large study with almost 1400 patients entered by 44 practices. Gender distribution was almost equal: 47% girls vs. 53% boys. Children ages newborn to 14 who presented to the doctor with a cough of up to one month's duration were eligible for the study. The results indicate that physicians felt that parents expected antibiotics in only 15% of cases. However, if physicians sensed that parent's wanted abx treatment diagnosis of bronchitis doubled. If diagnosis of bronchitis was made 27% of parents expected abx treatment vs. 9.5% parental expectation when diagnosis was not made. There were no differences in parental expectation due to the sex of the child, age, or duration of cough. This study supports the idea that if physicians perceive the patient (child and parent) to expect treatment they are more likely to prescribe abx.

    Is this expectation that physicians feel from their patients truly the patient's wish or is it something that comes from within physicians? At the end of the day is clinical judgment being undermined by what physicians perceive are their patients' expectations? These studies reinforce the need for increased physician-patient communication. Perhaps educating our patients about the appropriate use of antibiotics will not only decrease the patient's expectations but allow the physician to feel better about not prescribing them.

    For further information about the correct use of antibiotics please go to the CDC website: Campaign for Appropriate Antibiotic Use in the Community.


    More wine please!
    We have heard a lot about alcohol consumption reducing the risk of cardiovascular disease by elevating HDL and lowering LDL.  However, a recent study found that male drinker with high cholesterol who had a certain gene type did not benefit from alcohol consumption.  In fact their LDL cholesterol increased due to alcohol use.  This effect was not seen in female drinkers.  This study used a cross-sectional design to look at the male participants, which were a subset of the Framingham Heart Study.  These males carry the apolipoprotein APOE gene type 4.  Instead of having all our male patients get a genetic test, patients should have their cholesterol checked while drinking alcohol (less than two drinks per day), then have their cholesterol checked after eliminating alcohol from the diet and see how their LDL is effected.

     

    What are the other benefits to alcohol consumption? This study noted a strong association between alcohol intake and improved bone density.  Whole grains contain silicon, which is the ingredient in alcohol that has the positive effect.  Beer showed the strongest association with increased bone density.  Wine showed moderate association, and hard alcohol showed no association.  Beer has the greatest effect because it contains silicon in the most absorbable form.

     

    What are the risks of alcohol consumption? This study found that some forms of alcohol play a role, both beneficial and harmful, in cataracts.  Alcohol may affect different areas of the lens differently.  The researchers found women who drank more than two glasses per week of any type of alcohol increased the risk of nuclear opacity by 13%.  However, women who drank more than two glasses per week of wine or spirits were less likely to develop a cortical opacity.

     

    As long as you stay within the guidelines of moderate drinking, less than two glasses of alcohol per day for men and less then one glass of alcohol per day for women, you will benefit by improved cholesterol and strong bones.  Remember if you are a male have your cholesterol checked during a period of drinking and during a period in which you abstain from drinking.  The effects of the cholesterol test will inform you whether you have the APOE 4 gene.


    To DRE or not to DRE

    As part of routine health screening in men over the age of 40 or 50, digital rectal exams (DRE) and prostate specific antigen (PSA) levels are considered routine. Last week my preceptor, one of the nurse practitioners, and I were discussing the effects of the DRE on the PSA test. There was some disagreement whether the PSA level can be falsely elevated after prostate massage during the DRE. At my family practice office, we do not draw blood, but rather send patients to outside laboratories for required blood work, so it is an important consideration whether patients should wait a few days after getting a DRE to have their PSA levels drawn.

    This study compared the PSA levels before and 30 minutes after DRE in 91 patients referred to urologists. "The post/pre-DRE ratio of serum total, calculated complexed, and free PSA and percent free PSA was x1.5, x1.22, and x2.5 and x1.7, respectively." What these results suggest is that the act of doing the DRE tends to elevate the PSA, but it is unclear whether it can elevate PSA enough to lead to a significant false positive rate.

    This article, from American Family Physician, discusses how DRE and PSA together detect more cases of prostate cancer than either one alone, at the expense of a higher false-positive rate.

    Ultimately, then, PSA and DRE are both essential parts of prostate cancer screening, and both are recommended by national physicians' groups. It seems to me that if possible, blood should be drawn for the PSA before the DRE is performed, but if that luxury is not available (as at my office) you should still do both tests, and perhaps encourage patients to wait a few days to have their blood drawn to avoid false positives. I was unable to find an article about how long one should wait, but I'll keep looking.


    Colposcopy

    Background: A colposcopy is a way your doctor can examine your genitals, vagina and cervix closely. A colposcope is an instrument that shines a light on the cervix and magnifies the view for your doctor. At the beginning of the exam, you lie back and place your feet in the stirrups as you would for a Pap smear. Your doctor inserts a speculum into your vagina and opens it slightly so he or she can see your cervix. Then your doctor applies a vinegar solution to the cervix and vagina with a cotton ball or swab. The vinegar makes abnormal tissue turn white so your doctor can identify areas that may need further evaluation. If your doctor sees areas of abnormal tissue during the colposcopy, he or she may also perform a biopsy. This involves removing small samples of tissue from any abnormal areas in or around the cervix.
    Indication: Colposcopic testing is indicated any time a malignant lesion or precursor is suspected in the cervix, vagina, or vulva.The most common reason for performance of a colposcopy is in the evaluation of a woman with an abnormal finding on a Pap smear. Currently, almost all pathology laboratories use the Bethesda system for reporting findings of cervical cytology.
    Discussion: The Bethesda System for reporting cervical cytologic diagnosis:

    • Adequacy of specimen for evaluation: Transformation zone [TZ] sample is assured if both squamous and columnar cells are identified in specimen; the reason for inadequacy should be described.
    • Negative for intraepithelial lesion or malignancy: Listing benign findings (eg, trichomonas, atrophy, reparative changes) is optional.
    • Epithelial abnormalities
      • Squamous cell
        • Atypical squamous cell (ASC)
        • ASC of undetermined significance (ASCUS) 
        • ASC cannot exclude high-grade lesion (ASCH)
        • Low-grade squamous intraepithelial neoplasia (LGSIL) 
        • High-grade squamous intraepithelial neoplasia (HGSIL) 
        • Squamous carcinoma
      • Glandular
        • Atypical glandular cells (AGC), ie, endocervical, endometrial, or not specified
        • AGC favoring neoplastic
      • Endocervical adenocarcinoma in situ
      • Adenocarcinoma

    Colposcopy is ideally suited to help accurately evaluate lesion severity so that an appropriate treatment plan can be instituted. The 2001 Bethesda conference recommended that all women with Pap smear findings of LGSIL or ASCH be triaged for colposcopic evaluation. Subsequent treatment is based on colposcopic and directed biopsy findings. Women with ASCUS findings can be evaluated by repeat cytology, by HPV DNA analysis (if Pap smear was performed with liquid-based preparation), or by colposcopy. Women with ASCUS readings and findings on HPV DNA testing that are negative for high-risk viral types may return to annual cytologic screening.


    Thoracic Outlet Syndrome

    A 61 year old woman comes to the office complaining of pain, burning and a tingling feeling on the medial aspect of her left arm.  The pain started 7 days ago, after she carried a heavy bag, it's a continuous pain, tylenol, motrin and other OTC meds do not help. The pain has not gotten worse since it started.  This has happened before after she had an axillary lymph node the size of a tennis ball removed 12 years ago.  She's had no trauma to the area, no chronic illness, takes no meds and has no other complaint.  After a series of manipulations and discussion a Doctor of Osteopathy (D. O.) diagnosed her with Thoracic Outlet Syndrome (TOS).  She was happy that someone finally knew what was going on with her.

    Thoracic Outlet Syndrome cosists of a group of disorders that affect the brachial plexus or any nerve and blood vessels that pass between the base of the neck and the axilla.  As you can imagine the signs and symptoms vary, may be confusing, and is also poorly defined.  The only form of this syndrome that is agreed upon is True neurologic TOS.  This is rare, painless and is caused by a congenital anamoly.  The only symptoms are numbness, muscle wasting and weakness.  A goos history and physical are most important when making this diagnosis.  Some questions to ask and physical maneuvers are included at this site.

    Disputed TOS is another form that is quite controversial.  Some doctors say that it exist, others say it doesn't.  The most common presentation is pain.  There may be some weakness or fatiguw.  Scientists believe that this is also caused by injury to the brachial plexus.

    Vascular TOS is rare, this doesn't mean that we don't need to know about it.  Arterial TOS caused by compression of the subcalvian artery and results in  sensitivity to cold, numbness, sores/ulcers and pain in fingers, limb ischemia and occurs most commonly in young people.  Venous TOS is caused by compression of the subclavian vein and has a sudden onset, affects men and women equally and it's cause is unknown.

    Combined Neurovascular TOS or Traumatic TOS is caused by repetitive motion, hyperextension injury, accidents or any trauma that affects the nerves and vessels of the axilla.  The most common complaint is pain, also paresthesia and sensory loss. 

    How is TOS treated?

    My patient was scheduled for an Osteopathic Manipulation Therapy (OMT) session at the clinic.  Treatment depends on the type of TOS.  Surgery is first-line treatment for True Neurologic TOS and second-line treatment for all other types of TOS.  Symptomatic treatment with analgesic, shoulder exercises, warm compresses may be helpful.

    Prognosis for patients who receive treatment is good.

     

     


    No Flu Vaccines- What else can be done?

    Early estimates show that 12-23% of all U.S. residents will get some strain of the flu this year. Of those, the CDC predicts that as many as 100,000+ patients will be hospitalized for complications related to the flu.

    Perhaps it's due to the law of supply and demand, or maybe it's because it's been all over the news lately, but this year especially there seems to be much talk about the shortages of flu vaccines all across America. Many patients have expressed their concerns about not being able to be vaccinated and have asked if there was anything that they could do about the flu?

    On the CDC website, there list of recommendations to avoid getting the flu include:

    - Avoid close contact with people who are sick. When you are sick, keep your distance from others to protect them from getting sick too.

    - If possible, stay home from work, school, and errands when you are sick. You will help prevent others from catching your illness.

    - Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick.

    - Washing your hands often will help protect you from germs.

    - Avoid touching your eyes, nose or mouth. Germs are often spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth.

    The CDC has also approved four antiviral drugs for the prevention and treatment of the flu including: amantadine, rimantadine, zanamavir and oseltamivir. If taken within 2 days of getting sick, these drugs can reduce the symptoms of the flu and shorten the time you are sick by 1 or 2 days and can also make you less contagious to others. When used for prevention, they are about 70% to 90% effective for preventing illness in healthy adults.

    For those that are interested in a more natural alternative, research has found that Sambucol (SAM) (which comes from the elderberry plant) is an effective treatment for the flu. In one placebo-controlled double blind study, a significant improvement of the symptoms, including fever, was seen in 93.3% of the cases in the SAM-treated group within 2 days, whereas in the control group 91.7% of the patients showed an improvement within 6 days (p < 0.001). A complete cure was achieved within 2 to 3 days in nearly 90% of the SAM-treated group and within at least 6 days in the placebo group (p < 0.001)

    ASA and HTN

    Aspirin (ASA) is one of the most common NSAIDs used in prevention of CV events. 

    Interesting stuff about ASA: 

    1. ASA affects lipoperoxides, Beta-adrenergic receptors, and BP in a circadian pattern. 
    2. ASA inhibits collagen-induced platelet aggregation in a circadian pattern
    3. ASA has a faster clearance rate when taken in the morning

    This study:

     In this study 100  untreated healthy men (34) and women (66)  with average of 42.5 with mild essential hypertension were divided into 3 treatment groups. 

    Group 1: nonpharmocological hygiene-dietary

    Group 2: group 1 recommendations and aspirin (100 mg/d) on awakening

    Group 3: group 1 recommendations and aspirin (100 mg/d) before going to bed

    Treatment lasted for 3 months.  BP and HR were measured every 20 mins during the day and every 30 mins during nights starting 3 months before treatments and after treatments. BP and HR were automatically measured by the SpaceLabs 90207 device (I have no idea what this is!??!, but apparently it is reliable). 

    Baseline characteristics for age, height, weight, BMI, waist and hip perimeters, and BP were similar between the 3 groups.

    Results:

    - Nonpharmacological intervention: small nonsignificant reduction in BP (<1.1)

    - NO change in BP when ASA in the morning

    - Significant BP reduction in those who got ASA before bedtime (decreased by 6 and 4 mmHg in systolic and diastolic BP)

    - Night time dosing = 37% fewer gastric hemorrhagic lesions and is better tolerated

    -  If you have an untreated patient with mild HTN: give low dose ASA before bed time for secondary prevention of CV disease. ASA could also help control BP of those with mild essential HTN who do not comply to hygiene and diet recommendations.


    Will this drug give me pneumonia?!

    Recently, an 83 year old woman came into the practice for a routine check-up of her diabetes.  She is recovering from multiple myeoloma and is taking Nexium to protect from GI ulcers caused by her chemotherapy.  However, she recently read a article that linked PPIs and H2 blockers with an increased risk of pneumonia.  Given her age and state of health, combined with the lack of flu vaccine available, she was worried about contracting pneumonia if she remained on the Nexium.

    At least one study has shown that taking acid reducing drugs such as PPIs and H2 blockers increases the bacterial and fungal colonization of the stomach.

    The source of the newspaper report was a JAMA article (full text) that studied the link between community-acquired pneumonia and these acid reducing drugs.  They found that the relative risk of PPIs in contracting pneumonia was 1.89 with H2 antagonist use having a relative risk of 1.63 when compared to controls.

    In a commentary on this study, it is pointed out that the acid suppression these drugs provide can be critical in the treatment of reflux disorders or, as in this case, as prophylaxis for stress ulcers.  The author concludes that we must carefully weight the benefits of these drugs with the potential risks of adverse events.

    So what should this patient do?  While she is diabetic and at increased risk of infection, she has had her pneumonia vaccine.  Additionally, with her current course of chemotherapy, she is at a greatly increased risk of gastric ulcers.  Given this information, we decided that the best course of action was to reassure her that the Nexium was an important part of her treatment and she should continue to take it.

    Does anything work for low back pain?

    Many patients come in complaining of chronic low back pain (an excellent article about causes, evaluation, physical therapy, and meds).  The causes are as diverse as the patients, but if any of you have suffered from it, you know that it makes doing almost anything quite uncomfortable.  Some people want drugs (muscle relaxants, NSAIDs, narcotics) and some people want to do something about it (physical therapy, chiropractic).  Often, people have tried differect things without results and ask about what else they can do.  One patient I saw tried PT and meds, but neither seemed to work.  She asked about chiropractic

    While it's not really known how chiropractic manipulation actually works, it does help some people (myself and my preceptor included).  We both told her that we had no idea how it worked, had tried everything else (muscle relaxants, massage, PT, core strengthening exercies), and went into it totally skeptical, but somehow it seemed to do the job.  I still don't know if I really buy into it, but a few visits to the chiropractor made my back stop hurting when nothing else did.

    This study (although you can access the full-text through AMC Intranet, it can't be linked) randomized 681 patients into 4 treatment groups: medical care +/- physical therapy and chiropractic care +/- physical modalities in an effort to see which would work best.  The results showed that medical care (muscle relaxants, stretching, and/or NSAIDs) and chiropractic care were comparable to each other, and that the addition of physical modalities (heat/cold therapy, ultrasound, e-stim, soft-tissue/joint mobilization, traction, and strengthening and flexibility exercises) slightly increased improvement after 6 months. 

    Basically, I have not found any good studies that says one treatment is definitely better than the others for low back pain.  Most of the studies I've found showing that chiropractic was more effective than medical care have been in the Journal of Manipulative and Physiological Therapeutics.  I felt this journal could be inherently biased towards chiropractic care.  The study I picked was in Spine, which is probably biased towards allopathic care.  With that in mind, I felt that if Spine showed any benefit for chiropractic care, it would have had to overcome this bias first, which it did.

    It seems that with chronic low back pain, you have to go with what works for the patient and that it may require trials of different things.  I would tend to want to try physical therapy to try and get a long-term solution before putting people on potentially addictive drugs.  And I would say to keep an open mind towards chiropractic care as it works for some people and patients may ask for it.  Because of this, it might not be a bad idea to find a few reputable chiropracters to whom patients may be referred if they ask for it in order to make sure they aren't going to quacks

    "To Pee or Not to Pee"....That is the Question!

    Does post-coital voiding prevent urinary tract infections in young women? A small case-controlled study was looking to identify possible risk-factors for developing UTI's among young healthy women. A total of 225 women were enrolled in the study; excluded were women with diabetes, ant vaginal infections, a history of recurrent UTI's, recent catheterization, and pregnant women.  The women were surveyed regarding sexual, dietary, and clothing habits, as well as birth control methods.

    From mid-stream urine samples, the authors identified 44 cases of UTI and 181 controls presenting to the health center without urinary symptoms or a history of UTI. A UTI was defined as the presence of more than 50,000 colony forming units of a single species of bacteria per milliliter of urine and the report of 1 or more of the following symptoms: painful urination, frequent urination, urination at night, and urgent need to urinate, or blood in the urine. A primary UTI case was further defined as a not having had a prior history of UTI; a secondary UTI case was defined as a patient who reported 1 prior UTI.

    Women who urinated less than 15 minutes after intercourse had an estimated reative risk of .40 (95% CI 0.09-2.17) of developing a primary UTI (first time) and relative risk of .92 (95% CI .18-4.88) for developing a secondary UTI. These findings were not statistically significant but the power of the study was too low to rule out a potential effect. So, there is still no consensus between researchers and physicians as to weather urinating after intercourse has any benefit, but since there's no harm in doing it, it still may be worth encouraging! And In my opinion, if you've gotta go,you've gotta go don't hold it!

    "To Pee or not to Pee....That is the question" and it looks like there's still no answer!

    Up, Up, and Away!!!

    Maybe some of you have had the same experience as I have had in dealing with erectile dysfunction...no one wants to talk about it!  Instead of it being a primary complaint on the patient list, or one of the initial topics of conversation how do your patients present the topic to your doctor?  My experience has been that after a review of the patient's health and any acute problems, there's always... "wait one second, there's something else...."

     

    Half the time the patient usually asks me to leave or when they don't, they look rather embarrassed discussing their concern.  It seems fairly clear to me that despite the recent advertisements by the pharmaceutical companies and more people taking medications for it, there could be less of a stigma associated with the problem.  However, that's really not the case. 

    PDE-5 inhibitors have revolutionized the treatment options for this common problems and are viewed as a "miracle" for so many patients.  Each drug claims different advantages over the other and you've all seen the commercials for Sildenafil, vardenafil, and tadalafil.  Most patients now can be managed by a normal GP as opposed to having to see a urologist.  However, sometimes the problem isn't physiologic, but rather, it's between the ears.  Whether it was a bad first sexual experience with that partner, or a comment, it very well could be a mental health issue.  That's something that needs to be addressed. One article that discusses the varying problems associated with ED and the anticipation of it's resolution is very informative and easy to read.  This article is very good in discussing some of the mental health aspects of ED and the behaviors that follow.

     

    Another good source for information on ED, and noted the Massachusetts Study which found the prevalence of ED to be between 44 - 52% in males ages 40-70.  The study is the "first cross-sectional, community-based, random-sample multidisciplinary survey on the topic with a significant follow-up cohort."  It is also a great source for more information on the physiology of ED as well as some comparisons between the different oral therapies.

     

    The final article found that depending on the background of the physician (male or female, embarrassment level with the topic, patient population) determined their likelihood of prescribing an oral agent for treatment.

     

    One common theme that ran through these articles was the tie-in to the pharmaceutical industry itself.  While we, as a profession, should expect the best science possible, it is an increasing problem that scientists receive incentives from pharmaceutical companies, are paid for speaking engagements, and receive grants.  While an ethical scientist should be objective in their findings, one should be careful when reviewing their medical journal data for any sort of bias.  Certainly, these articles might be guilty of some.


    Which is the best statin?
    Not surprisingly, I have seen many patients who have been diagnosed with Metabolic Syndrome.  Obviously, one of the best ways to treat this is weight loss.  However to decrease the risk of developing Coronary Heart Disease, we need to treat the various aspects of this syndrome with medications.

     

    Dyslipidemia resulting in plaque formation is a major cause of morbidity and mortality in patients with Metabolic Syndrome.  Thankfully, we have the statins to help protect our patients from having a vascular event.  But given the enormous number of statins on the market, how can we choose the correct one for each patient?

     

    • This study compares rosuvastatin (Crestor), atorvastatin (Lipitor), simvastatin (Zocor), and pravastatin (Pravachol).  Rosuvastatin was more successful in reaching lipids goals.

       

    • This study reports that simvastatin has the lowest number of treated patients to prevent one major coronary event.

       

    • Finally, this study discusses the benefits of treating coronary heart disease with both ACE inhibitors and statins.  The group of patients being treated with both an ACE inhibitor and a statin had a reduced number of cardiovascular events.

    Treatment for Dementia

    Mrs. J and her daughter, DJ, came in for a follow up visit.  DJ was concerned that her 75 year-old mother was not her usual self lately and that she was forgetting things more and more every day.  Mrs. J did not think she had a problem and attributed it to simply old age.  The doctor decided to put Mrs. J on memantine, otherwise known as namenda. 

    I was curious to know exactly how memantine worked and whether it would actually help Mrs. J from further losing her memory.  Memantine is an NMDA receptor antagonist that is found to reduce overstimulation of the NMDA receptor.  This reduces excitotoxicity and, in turn, has neuroprotective effects.  This article is a double-blind study of patients over the age of 60 with vascular dementia.  After 28 weeks of treatment, this study found that patients taking memantine had significantly improved cognition compared to patients taking the placebo.   Since memantine has few side effects of mild to moderate severity, it is relatively safe for patients to use. 


    Teenage sex
    A 13 year old girl came into the office complaining of a vaginal odor.  The nurse took the sexual history and found out that the patient engaged in sex one time about six months prior.  The mother was shocked that her 13 year old daughter was having sex.  The mother thought that the reason her child engaged in sex was because of low-self esteem secondary to obesity.  The mother asked the doctor to refer her child to the nutritionist for a weight loss plan.  In addition, the mother spoke of changing her working hours so she could be home to supervise the child.  Will the mother's increase in supervision have an effect on her child's sexual behavior?
     I found this article in the journal Pediatrics.  The authors conducted a cross-sectional survey in six public schools in an urban area.  The study found that 91% of the respondents had their last sexual experience in a home setting.  Also, youth who were unsupervised for 30 hours or more per week were more likely to be sexually active than youth who were unsupervised less than 5 hours per week.  The study concluded that as the amount of unsupervised time increased the prevelance of high risk behavior increased.


    Insulin resistance and polycystic ovary syndrome

    Mrs. G., a 36 year old woman, came into the office last week complaining of right lower quadrant pain that occurred on a semi-monthly basis between menstrual cycles. When my preceptor and I were discussing the differential diagnosis, among the considerations were mittelschmertz (I love saying that), ectopic pregnancy, UTI, appendicitis, and polycystic ovary syndrome. And in addition to other blood work and an ultrasound of the pelvis, we decided to screen her for diabetes mellitus. Why, you ask? Well I wondered the same thing and was surprised to find a very strong connection between polycystic ovary syndrome and diabetes mellitus.

    I was surprised to learn that 5 - 10% of women of childbearing age have polycystic ovary syndrome (PCOS), and that 50 - 70% of women with PCOS have some degree of insulin resistance. This resistance to insulin leads to a hyperinsulinemic state which is hypothesized to contribute to many of the clinical features of the syndrome: androgen excess, anovulation, dyslipidemias. This is a good review of PCOS.

    And there is a lot of literature out there discussing the link between PCOS and diabetes mellitus (DM). In having either one of these conditions increases one's risk of having the other 5 to 10 times. This review discusses current thinking about the two conditions. Some hypothesize that PCOS and DM are essentially variations on the same disorder, one in which the ovaries are affected and the other in which the pancreas is affected. One final interesting fact I learned is that in PCOS there is kind of "selective insulin resistance" in which organs like muscle and adipose are resistant to insulin leading to obesity, dyslipidemias, etc.; and organs like the adrenals are hypersensitive to insulin leading to increased androgen production and the associated symptoms like anovulation, hirsutism, etc.

    I guess the take home point of this posting is to suspect PCOS in your patients and remember to screen for DM in these patients and vice versa.


    Managing SCD

    I got a patient in the office the other day that was a black 13 year old female with sickle cell disease.  She suffers from many bouts of painful occlusive episodes which are well controlled with pain medication.  She had a recent run-in with avascular necrosis of the femoral head, for which she received a hip replacement and subsequent DVT.  I saw her in the office because we are trying to manage her DVT and prevent thromboembolism with coumadin.

    This was my first ever sickle cell patient, so I decided to look into what kinds of things these patients must cope with at such a young age, and what can be done to help them cope and maintain a good quality of life.  A great study I looked at analyzed different ways to help optimize sickle cell patients' well being.  They concluded that efficacious psychosocial interventions delivered in a manner appropriate for children can significantly help.  Current evidence suggests that cognitive-behavioral techniques are probably efficacious for reducing children's SCD pain.  Cognitive strategies (such as calming self-statements, hypnosis, and imagery) and/or behavioral strategies (such as biofeedback and progressive muscle relaxation) were examined and showed to significantly help patient's coping and outlooks on life.  While many times we treat patients for their physical afflictions, it is easy to overlook the mental struggles that go along with them, and it's important to help them with this aspect of their disease as well.


    Postpartum depression
    Background: Postpartum depression is a type of major depression that affects about one in 10 new mothers within the first year after they give birth - although it usually hits shortly after childbirth. If postpartum depression goes undetected or untreated, not only does the mother suffer, but the child is at high risk of developing emotional, behavioral and cognitive problems. The disorder typically lasts about 12 months.
    Question: How to recognizing and treat postpartum depression?
    Discussion: The following signs of postpartum depression include:
    • Feeling restless or irritable.
    • Feeling sad, depressed or crying a lot.
    • Having no energy.
    • Having headaches, chest pains, heart palpitations (the heart being fast and feeling like it is skipping beats), numbness, or hyperventilation (fast and shallow breathing).
    • Not being able to sleep or being very tired, or both.
    • Not being able to eat and weight loss.
    • Overeating and weight gain.
    • Trouble focusing, remembering, or making decisions.
    • Being overly worried about the baby.
    • Not having any interest in the baby.
    • Feeling worthless and guilty.
    • Being afraid of hurting the baby or yourself.
    • No interest or pleasure in activities, including sex.
    A woman may feel anxious after childbirth but not have postpartum depression. She may have what is called postpartum anxiety or panic disorder. Signs of this condition include strong anxiety and fear, rapid breathing, fast heart rate, hot or cold flashes, chest pain, and feeling shaky or dizzy. Talk with your health care provider right away if you have any of these signs. Medication and counseling can be used to treat postpartum anxiety. It is important to know that postpartum depression (PPD) affects women of all ages, economic status, and racial/ethnic backgrounds. Any woman who is pregnant, had a baby within the past few months, miscarried, or recently weaned a child from breastfeeding can develop PPD. The number of children a woman has does not change her chances of getting PPD. New mothers and women with more than one child have equal chances of getting PPD. Research has shown that women who have had problems with depression are more at risk for PPD than women who have not had a history of depression. Postpartum depression (PPD) is treatable and that it will go away. It is important to know that postpartum depression (PPD) is treatable and that it will go away. The type of treatment will depend on how severe the PPD is. PPD can be treated with medication (antidepressants) and psychotherapy. Surprisingly, only one
    randomized study has evaluated the pharmacological treatment of postnatal depression. The study entailed a comparison of four treatment groups (total n = 87): fluoxetine plus a single session of cognitive behaviour therapy; placebo plus a single session of cognitive behaviour therapy; fluoxetine plus six sessions of cognitive behaviour therapy; and placebo plus six sessions of cognitive behaviour therapy. After four weeks of treatment, similar improvements occurred among women receiving either six sessions of cognitive behaviour therapy, or fluoxetine plus one session of cognitive behaviour therapy. The study shows that women's choice of treatment may be guided by their preference of pharmacological or non-pharmacological approaches as both seem comparably effective. Several studies have reported that antidepressants, including sertraline, paroxetine, venlafaxine, and nortriptyline, can be used safely by nursing mothers of healthy full term infants. Fluoxetine has been linked with irritability, sleep disturbance, and poor feeding in some infants exposed to it in breast milk, although other reports have not noted adverse incidents. Although the data regarding antidepressants during breast feeding are generally favourable, little is known about the long term effects of exposure to antidepressants on the child's developing brain. Many new mothers remain reluctant to take such medications while nursing.
    Conclusion: There is evidence that postpartum depression improves with antidepressant drug therapy, estrogen, individual psychotherapy, nurse home visits, and possibly group therapy. Of the more frequently studied antidepressant drugs in breastfeeding women, paroxetine, sertraline, and nortriptyline have not been found to have adverse effects on infants. Fluoxetine, however, should be avoided in breastfeeding women. By administering effective treatment to women with postpartum depression, we can positively impact the lives of mothers, their infants, and other family members.


    Childhood Vaccinations cause Brain Tumors!!??!!
    Last week I had a mom and her 4 month old daughter come in for her daughter's 4 month physical. After doing the history and physical I told the mom that her daughter did need some vaccinations this visit. Then the mom said that was something she actually wanted to talk about. I knew there were people who were against immunization for religious or personal beliefs, but this was the first patient I had encountered who didn't want them. We had a really interesting conversation. The mom didn't want immunizations not due to religious reasons, but because of research she had done on the internet. She told me the things she had read had terrified her. This surprised me because I had no idea how much literature was out there against immunizations. I was curious so I went on the internet to find some of the arguments against immunizations. I found one story citing a link between vaccinations and brain tumors. There is one site by a physician stating a link between vaccination and neurological disorders, such as autism and ADHD. There was another site that stated there was a link to vaccines and type 1 diabetes and whole host of other disorders. To be honest, all the information on the internet is scary, and it is hard to weed out fact from fiction. We ended up talking to this mom for a while, and we referred her to credible websites like the American Academy of Family Practice and the American Academy of Pediatrics sites. We also told her that we would discuss any article she found opposing immunizations, and would try to see if there was any scientific or substantial data to back the claims.

    From the research I did, I found very little scientific data to back some of the claims made. For instance, there was a large cohort study done in Denmark investigating the correlation between immunizations and type 1 diabetes. This study found no correlation. Some people say that the MMR vaccine increases a child's likelihood of autism. There was a study done to investigate this, and they found that there was no evidence to support a distinct syndrome of MMR-induced autism or of "autistic enterocolitis and there failed to be an association between MMR and autism. The story citing a link between vaccinations and brain tumors wasn't a completely objective story. It was written by distraught parents who were trying to find out why their son was diagnosed with medulloblastoma. There was a study done examining a contaminant (simian virus 40) of the early polio vaccine, which was thought to be connected to various cancers. This study found exposure to simian virus 40-contaminated poliovirus vaccine was not associated with increased cancer incidence.


    There is a lot of information out there and it is difficult to sort out. In this case, the best thing to do was to offer this mom credible sources of information. In addition to the FP and Peds website, this is a good site that has basic information about immunizations in plain English for parents who would like to know more.


    the skinny on the flu vaccine

    I'm sure most of you have encountered a few pts requesting the flu vaccine that do not qualify under CDC's guidelines.  To refresh your memory, pts that should be receiving the flu shot are:

  • People 65 years of age and older
  • Children ages 6 months to 23 months
  • Adults and children 2 years of age and older with chronic lung or heart disorders including heart disease and asthma
  • Pregnant women
  • Adults and children 2 years of age and older with chronic metabolic diseases (including diabetes), kidney diseases, blood disorders (such as sickle cell anemia), or weakened immune systems, including persons with HIV/AIDS
  • Children and teenagers, 6 months to 18 years of age, who take aspirin daily
  • Residents of nursing homes and other chronic-care facilities
  • Household members and out-of-home caregivers of infants under the age of 6 months (Children under the age of 6 months cannot be vaccinated.)
  • Healthcare workers who provide direct, hands-on care to patients
  • However, surprisingly, there are a few pts or parents of pts that do fall into one of the above high risk groups and refuse the flu vaccine.  Several of these people refuse the shot because they believe that the vaccine is not effective especially because of the chance of not matching the predominant influenza strain that particular year.

    These two studies assess the effectiveness of the influenza vaccine among children and adults during the 2003-2004 flu.  Despite the mismatch of the vaccine strain and the predominant circulating influenza that year, it was found that the influenza vaccine had 25-49% effectiveness against nonlaboratory-confirmed influenza and 38-52% effectiveness against laboratory confirmed influenza in preventing illness.  Although this is less than the expected 70-90% effectiveness when the vaccine strain is well matched to the predominant circulating strain, this is still a substantial health benefit and huge decrease in mortality and morbidity.

    Furthermore, the studies found that there was no significant difference between unvaccinated children and children who were only partially vaccinated (received only one dose versus two).  Thus, don't forget to schedule children who are receiving the flu vaccine for the first time for a second dose one month after the first dose.

    During this time of vaccine shortage, it may be easier to let a misguided, high risk pt that refuses the vaccine to go without it in favor for someone who really wants it.  However, it may be a good idea to see why he/she refuses and possibly dispel any myths for him/her.


    Maggot Therapy (yes- that's right) for treating Diabetic Foot Ulcers

    I find it interesting that virtually every examining room at the office where I have been learning / working has a sign that says: "If you are a diabetic, kindly remove your shoes and socks." It is ingrained into us as medical students that one of the most important parts of the physical exam of the diabetic patient is the examination of the feet. It is important to observe and test for signs of peripheral vascular disease and neuropathy in order to prevent such complications as ischemic skin ulcers, cellulitis and osteomyelitis, and in so doing, to prevent the need for amputation of a foot or leg.

    I found this study very interesting because as the author has highlighted, "Almost 15% of all diabetic patients will develop one or more foot ulcers, and 15-25% of those will ultimately require amputation." (referencing Frykberg's Epidemiology of the Diabetic Foot: Ulcerations & Amputations" Advanced Wound Care 12:139-141, 1999) "It is no wonder that one of the disease prevention objectives outlined in the ‘Healthy People 2000' project was a 40% reduction in the amputation rate for diabetic patients. That objective has not been met, despite many advances in wound care." (referencing National Center for Health Statistics: Healthy People 2000 Final Preview. Hyattsville, MD, Public Health Service, 2001)

    In this study, Sherman evaluated wounds of diabetic male veteran patients that were not improving with conventional care. It showed that maggot debridement therapy (MDT) was more efficacious when treating these chronic wounds refractory to initial conventional therapy than was a trial of another standard therapy. Conventional or standard wound care treatments were described as: non-medicated dry dressings or saline-moistened ‘wet-to-dry' gauze changed every 8 hours; topical antimicrobials administered three times per day; and non-surgical as well as surgical debridement (three times per week) methods.

    Once 143 patients were deemed appropriate candidates for MDT (between the years 1990-1995), 18 of these patients were ultimately chosen for inclusion in the study because their wounds were measurable by planimetry. Disinfected larvae of the fly Phaenicia (=Lucilia) sericata were placed in the wound (5-8 larvae per sq. cm.) with loose gauze. Several layers were applied atop the hungry critters: ring of hydrocolloid, covering of porous dacron chiffon (or nylon stocking), light gauze pad to absorb necrotic drainage (this outermost layer was replaced every 4-6 hours). The maggots and the inner 2 layers above them were left for cycles of about 48 hours. Approximately one-two cycles were applied each week. Patients in the control group continued to receive conventional therapy. Wound progression was analyzed by way of ulcer length, width, circumference and surface area - measured from digitized photographic images. Primary outcome measures were as follows: change in relative & absolute amounts of necrotic tissue, change in relative amounts of granulation tissue, change in wound surface area over time, and length of time until complete wound healing.

    Results of this study showed that maggot therapy has a better outcome in terms of debridement of nonhealing foot and leg wounds in diabetic male veterans than the usual standard wound therapy. MDT was found to be associated with a more rapid decrease in wound size and an increase in granulation tissue. These results were statistically significant. It was also found that there was a higher number of patients reaching complete wound closure within the 8-week study period with maggot therapy versus conventional therapy, however, these results were not statistically significant.

    Happy Halloween, everyone!


    Erectile dysfunction

    Background: erectile dysfunction is when a man can't get an erection to have sex or can't keep an erection long enough to finish having sex. Erectile dysfunction is also called impotence. Erectile dysfunction doesn't have to be a part of getting older. It's true that as you get older, you may need more stimulation (such as stroking and touching) to get an erection. You might also need more time between erections. But older men should still be able to get an erection and enjoy sex.

    Question: What are the benefits of phosphodiesterase inhibitors in the treatment of erectile dysfunction?

    Answer: The drug of choice is Sildenafil.

    Discussion: Sildenafil facilitates erections associated with sexual stimulation. It will not act if the man is not sufficiently mentally aroused or his peripheral autonomic nerves are absent (e.g. radical prostatectomy). It acts by inhibiting phosphodiesterase isoenzyme 5 (PDE5), thus prolonging cyclic guanosine monophosphate (cGMP) activity in erectile tissue, and enhancing the vasodilating actions of nitric oxide, which is released in response to sexual stimulation. Six randomized, double-blind, clinical trials comparing sildenafil versus placebo were published prior to June, 1999. Each trial enrolled between 12 and 532 patients over a duration of 2 to 24 weeks. In the best designed trial of 329 patients over 12 weeks, intercourse was reported successful in 59% of patients taking sildenafil as compared to 15% of patients taking placebo (absolute benefit increase 44%, NNT = 2 to achieve one success). The most common adverse effects, as absolute risk increase over placebo, were headache 14%, flushing 17%, dyspepsia 4%, rhinitis 4% and visual disturbance 1%. None of the studies assessed the effects of long-term sildenafil use. Such studies are needed, particularly in patients with a history of retinal and cardiovascular disorders. Serious rare side effects include priapism, severe hypotension, heart attack, stroke and death. The development of the PDE-5 inhibitors vardenafil and tadalafil prompts the question of whether and how these three substances differ in terms of their efficacy and adverse effects to sildenafil. The initial studies conducted, vardenafil and tadalafil demonstrate efficacy data approximately comparable to those of sildenafil. As yet, insufficient data are available to evaluate the adverse effects of vardenafil and tadalafil, particularly their long-term use and use in high-risk groups. - Sildenafil has already been used by over 20 million men in over 110 countries and is one of the best-studied pharmacological substances available. This adventage in terms of knowledge and safety data makes sildenafil a safe and reliable treatment for patients with erectile dysfunction.

    Conclusion: The development of phosphodiesterase inhibitors, which are selective for the type 5 isoenzyme, has revolutionized the initial evaluation and treatment of men with erectile dysfunction. These agents can be taken orally and are effective in 60-70% of patients with erectile dysfunction, and they have low incidences of side effects when taken as recommended. The major contraindications are concomitant use with nitrates or the alpha-blockers terazosin and doxazosin. The major difference in the three approved inhibitors is that tadalafil has a considerably longer serum half-life, which provides a longer window of opportunity and potentially side effects. As the new drugs stay longer one the market and prove to have better side effect profile, the longer acting drugs will be more favorable by the physician. For now physicians are sticking to sildenafil for its proven efficacy and side effects.


    Kava wreaks Hepatic Havoc!!!

     A 56-year-old woman  presents to the hospital, for investigation of jaundice. She had been previously well.The patient had presented to her local doctor with a two-week history of fatigue, nausea and increasing jaundice. She had no risk factors for viral hepatitis, no history of liver disease and drank minimal amounts of alcohol. Over the preceding three months she had been taking a herbal supplement for anxiety, prescribed and provided by a naturopath- KAVA. She had also been taking some vitamin and mineral supplements but no other medications.

    Basically, the docs at the hospital determined that this was serious jaundice without any signs of chronic liver disease. She had viral titers measured for all the typical etiologies, Hepatitis, EBV, etc...all negative.  Her condition deteriorated further and further until she was immediately put on the transplant list. Unfortunately the woman died from complications of the transplant.

    Subsequent analysis of the supplement she had taken revealed it contained kava and Passiflora incarnata as labelled, and a third, as yet unidentified, compound.

    Medication reactions resulting in abnormalities of liver function tests are relatively common, yet rarely result in severe liver injury. Therefore once again, it must be reiterated how important it is to take a careful history of any drug or herbal remedy use in all patients with unexplained hepatitis (or any illness!), as the continuation of the agent after the onset of injury may have catastrophic consequences.


    To use a lubricant or not...

    Working in the family practice office, I see a lot of women getting papanicolaou smears for cervical cancer screening.  However, some doctors use a lubricant on the tip of the speculum and some doctors prefer not to use it.  I also remember a doctor from the last rotation, who prefers not to use the lubricant for the pap smear because of the debate on the possible contamination of the pap smear sample. 

    However, one doctor that I worked with in the past week told me that the debate on the contamination of the sample by the lubricant has been resolved.  As my research results showed, she said the lubricant does not interfere with the pap smear result.  She also considered a patient's comfort as the most important reason for the use of the lubricant.

    Most textbooks on gynecology written in the past (prior to the publication of these studies), state that no vaginal lubrication should be used for pap smears in fear of adversely affecting the result.  One Ob-Gyn website by a medical school, copyrighted in 2001, also recommends the same, showing how pervasive this belief was prior to these studies.

    In order to elucidate the possibility of interference with the interpretation of the pap smear, investigators in this study collected pap smear samples from 182 patients, using a speculum with a water soluble lubricant or a speculum with water only.  Next, they sent the samples for analysis to cytotechnicians and pathologists who were blind to the cohort and to whether or not they were part of the study.  According to the result, 2.1% in the lubricant group and 2.2% in the no lubricant group had unsatisfactory result, showing no significant difference between the two groups.

    FYI: Unsatisfactory samples refer to smears that are "unsatisfactory for evaluation" : samples that have scanty cellular material or obscured by inflammation, blood, or debris so that more than 75 percent of the cells are uninterpretable.

    Another study published in the same issue of the same journal also found no difference in the pap smear results between the two groups.  This study analyzed over 8000 samples and found the rates of unsatisfactory sample in lubricant and no lubricant group to be 1.4% and 1.3% respectively.  They also investigated the rates of high-grade and low-grade squamous intraepithelial lesions and benign cellular changes in the two groups and found no significant difference.

    I could not find any study that associated the use of a lubricant with misleading or incorrect results(the authors in above studies could not either).  One website mentioned the use of a lubricant has been discouraged ‘traditionally'.

    I also could not find a study that investigated the level of pain and discomfort associated with a lubricant use on the exam.  However, if there's a possibility of decreasing pain and discomfort associated with the exam, why not use it?  Many women avoid pap smear because of the pain and discomfort despite its proven effectiveness for cervical cancer screening.


    Prostate Cancer Screening: To PSA or Not to PSA, that is the question!

    54-year-old R.S. came into clinic for a routine annual check-up.  With no major complaints and an unremarkable physical examination, my preceptor was finishing up the appointment by going over health maintenance issues.  When he got to screening for prostate cancer, he recommended a digital rectal exam (DRE) but not a PSA test.  Why not the PSA test?!!!  It was time to investigate!

    Prostate specific antigen, or PSA, is a protein produced by the prostate that may be found in low amounts in the blood of healthy men.  The amount of PSA in the blood normally increases as a man's prostate enlarges with age.  It may also be found in an increased amount in the blood of men who have prostate cancer, benign prostatic hyperplasia, or an infection of the prostate gland.   There is no specific normal or abnormal PSA level.  However, the higher a man's PSA level, the more likely it is that cancer is present.  But because various factors can cause PSA levels to fluctuate, one abnormal PSA test does not necessarily indicate a need for other diagnostic tests.  When PSA levels continue to rise over time, other tests may be needed. 

    I found one study that looked at the pros and cons for all types of screening for prostate cancer for the U.S. Preventive Service Task Force.  Their literature evaulation found that the benefits of screening for prostate cancer cannot be well determined (i.e. decreased mortality), although the risks of prostate cancer screening are known (i.e. erectile dysfunction, urinary incontinence).  This would suggest that all types of general screening for prostate cancer is unwarrented.  Not quite satisfied since I wanted to look at the validity of specifically PSA test for prostate cancer screening, the search continued...    

    Another study used a case-control format to evaluate the correlation between serum PSA and prostate cancer in 21,387 men in the Finnish Cancer Registry.  The sensitivity of PSA to identify cancer was 44% and specificity 94% with the clinically common cutoff of 4 µg./l.  The sensitivity increased to 86% if only cases occurring in the 5 years after the sample drawing were considered.  Patient age at the sample drawing affected the validity. The sensitivity was 93% and specificity 96% at the cutoff of 4 µg./l.  if only those men younger than 65 years at the time the sample was drawn with a lag of less than 5 years were included.  All men younger than 65 years with cancer in 5 years after the sample drawing had PSA greater than 2.5 µg./l., indicating 100% sensitivity, while specificity remained at 91%.  The authors concluded that although serum PSA is a valid test for screening prostate cancer, routine testing with PSA is not justified until an effect on mortality can be demonstrated.

    In conclusion, since there is no direct evidence whether or not early detection and treatment of prostate cancer reduces mortality because randomized clinical trials to address this question have not been completed, it seems PSA testing should not be used for routine screening.  PSA screening can cause harm by producing false alarms, inducing anxiety and the treatment of early disease whichwould not otherwise have become a problem.  But even though evidence does not yet support population screening for prostate cancer, there is considerable demand for the PSA test amongst men worried about the disease.  Therefore, presently the role of the general practitioner is to inform men of the PSA test and provide high quality information regarding the test so that they may make their own decision.


    Antibiotic ointment: Trick or Treat?

    Hi, just in case my links don't go through, I've included a list of resources at the end of my blog... :-)

    One of my more exciting patients last week was a man with a painful perianal abscess.  (Click here for a picture of one (5).) We consulted with a surgeon, who made an incision in the abscess to drain it.  The surgeon then left it open, filling it with a strip of thin cotton gauze which was to be removed the next day. 

    The surgeon remarked that no special antibiotic ointment or care was needed because "wounds around the anus don't get infected, despite all the schlong that passes by."  Actually, he went on to say that no open wound ever gets infected, and that in his opinion, antibacterial ointment is no more effective than Vaseline.

    Unfortunately, I couldn't find any articles specifically on whether or not an incised perianal abscess would get reinfected without an antibiotic ointment.  However, the review articles on treatment never mentioned using one.  Instead, postsurgical treatment often consists of rinsing with seltzer water after having a bowel movement. 

    I did find one article (6) comparing various antibiotic ointments with Vaseline.  It was a double blind randomised controlled trial.  Basically, 465 patients who presented to the ER within 12 hours of sustaining a wound (and who weren't immunocompromised, pregnant, taking antibiotics, etc.) were randomly placed in groups.  Patients either received an antibiotic ointment or Vaseline after the wound was cleaned, debrided, and sutured as needed.    The result was that patients given antibiotic ointment had a lower rate of wound infection than patients given Vaseline.  

    Weaknesses in the study (7) included subjective measurements of infection, patients were responsible for their own wound care, and the fact that every wound was initially treated differently.   According to doctors at Best Evidence Topics, there wasn't enough evidence to change our current practice of not using antibiotic ointment on wounds to prevent infection.

    Another randomized, double-blind, prospective trial compared white petrolatum with bacitracin ointment.  In this study, 922 patients were enrolled, with a total of 1249 wounds.  "Thirteen patients developed postprocedure infection (1.5%), 9 (2.0%) in the white petrolatum group vs 4 (0.9%) in the bacitracin group (95% confidence interval for difference, -0.4% to 2.7%; P=.37)"  Although the authors found do difference in wound healing and concluded that white petroleum is as safe and effective as an antibiotic ointment, their own study does show a lower rate of infection when bacitracin ointment was used.  However, 4 patients treated with the ointment developed an allergic reaction to it, whereas none of the petroleum patients had an allergic reaction.   
    The bottom line on all this?  It seems as if the consensus is that we don't need to use antibiotic ointment after wounds are treated, unless a large multicenter study is performed that proves otherwise.     

    For your Interest, Some Perianal Abscess Info:


    "A perirectal abscess is a collection of pus in the deep tissues surrounding the anus. By contrast, a perianal abscess is a shallower collection of pus under the skin surrounding the anus."  (3)  It is believed that a perianal/rectal abscess occurs when one of the mucous-secreting glands inside the anus gets blocked up.  The duct gets infected, swells and bursts, creating an abscess.  This abscess then tracks to the surface, where it presents as a fluctuant mass just under the skin.  Apparently, you can get an idea of how deep the abscess is by where it presents on the anus.  (For a diagram, click here and scroll down.)

    Treatment:
    These abscesses usually form inside the rectum, then track to the skin, so it is rare to find a truly superficial perianal abscess.  Ultrasound, MRI, or CT can be used to track the depth of the abscess, which often forms a fistula.  Basically, the abscess should be incised and drained.  However, it should not be tightly packed, since the gauze can become a hotbed of new infection and can cause sepsis.   If it were closed by stitches, pus would just form in the wound and recreate the abscess.

    Not The Nutritionist Again!

    This site is a great source for this topic.  I would have been linking the same site too many times throughout the blog.

    Just about every other patient I see has diabetes.  Within the past two weeks, none were referred to the nutritionist, nor were they asked about podiatry visits nor was diet mentioned.  On Friday, I saw a 41 year old woman who developed type 2 diabetes about 1 year ago.  Her diabetes is diet controlled.  I asked her about her diet, which she told me she has started to eat all the things she had stopped eating and from looking in her chart, she had regained the weight she had lost after her first and last visit with the nutritionist. 

    She gained the motivation to change her diet after meeting with the nutritionist 6 months ago.  She regained the weight, because she had lost the motivation to eat a proper diet.  I suggested another visit with the nutritionist since this is what had motivated her to lose some weight in the first place.  She told me that she had already seen the nutritionist, I convinced her to go to the nutritionist again (scare of meds/insulin :) )  Surprisingly, I precepted the patient and told the doc that I think the patient should see the nutritionist again and the doc's response was what the patient had said, "She already saw the nutritionist."

    The effective most successful management of diabetes requires teamwork.  Back in the days, the traditional or consultative approach, where the doctor was the leader and had the say so was used.  Today, the interdisciplinary or integrated team approach has been proven to work best in the management of diabetic patients and any patient with a chronic illness.  The basic team should include physicians, nurses, medical assisstants, dieticians, social workers and behavioral scientists specifically trained in the area of interest.  It takes a well collaborated  team effort to appropriately manage these patients.  Team members need to understand the disease process fully, understand the management approach, respect each other's point of view and role and they MUST COMMUNICATE.  They don't have to agree with each other, but they must all communicate regarding the patient.

    A large part of managing diabetes well is educating the patient.  The linked article provides result from a study, which showed that the educated patient is able to better monitor blood glucose levels and make better decisions regarding their health.  The patient who was previously mentioned with diet controlled diabetes should spend most of her time with the nutritionist.  The physician may be the team leader, but he or she does not have to be the one to spend most of the time educating the patient after the initial visit.  These patients may spend upto 60% of the visit with the nurse or whoever is able to educate them.  Each team is designed according to the specific needs of the patients.  This does not happen in this clinic.  The nurses do the routine stuff (BP, RR etc), that's it.  I haven't heard anyone ask about the diet nor money for the proper foods nor support systems.

    We should all try to remember to utilize the resources that are available to us as doctors.  A team approach to applicable patients may help to decrease our workload while providing the best possible care for our patients.


    Kava Kava

    A young guy (mid 20's) presented this week with generalized anxiety d/o exacerbated by sleep disturbances, tension, and restlessness. Having tried more conventional treatments such as benzodiazepine and SSRI he was wandering the efficacy of phytotherapy such as kava kava (piper methysticum) which he read on the internet could be of some benefit. What was I supposed to tell him??

    The first article that I came across seemed to be in favor of using Kava Kava extract for sleep disturbances that are associated with anxiety disorders. The study only used 57 patients (a small number I thought) 34 of which were assigned to take the extract while 23 were placed on the placebo. Both groups showed sleeping improvements but the Kava Kava group had a more pronounced improvement. The study claims that administration of kava increases deep sleep periods but unchanges REM sleeping periods unlike psychopharmacological agents used for anxiety which suppress REM sleep and prolong REM latency period. Patients taking Kava tolerated the treatment well without any adverse side affects. Patients with anxiety disorder claimed that being on the KAVA improved their overall well being and reduced their anxiety in part by the normalization of their sleep. The authors of this study supported the use of Kava for its affectivity but also for its lack of dependency creating potential.

    In another recent article the role of Kava was assessed in patients with anxiety. This study lasted for 4 weeks and included 50 patients with non-psychotic anxiety (DSM-III-R criteria). Anxiety levels were measured using the Hamilton Anxiety Scale (HAMA). This study concluded that a lower dose of Kava 100-300 mg/day can be efficacious for anxiety treatment while a higher dose can be comparable to benzodiazepines. The authors in this study pointed out that patients tolerated the drug well and that Kava has minimal drug interaction with other drugs. Therefore this study also supported a trial use of Kava in patients before beginning them on habit forming sedative psychotherapy.

    However, not everyone is supportive of the use of Kava Kava in the treatment of anxiety disorder. An Article (cannot link to OVID article) published in 2004 in Current Opinion in Psychiatry (VOL 17(1) pp49-52) reviewed recent developments in the research of generalized anxiety d/o and stated Kava Kava, although well tolerated, is not superior to Placebo. This information is important to keep in mind when we are educating patients about what we can realistically expect from a treatment such as Kava Kava.

    Lastly, it is important that we educate our selves and our patients about the potential side effects to the medications we prescribe them. A publication in JAMA pointed out the potential association of Hepatic toxicity with the use of Kava Kava containing products. Patients with pre-existing liver disease or are at risk for liver disease are advised not to use Kava products. Some countries such as Germany, Canada, Australia and France have restricted use of Kava based on its potential for hepatotoxicity.

    In conclusion we should not negate our patient's request for alternative medicine especially if we are not educated about the particular remedy. For my patient Kava may be a good choice to begin with because he did not want to resort to benzodiazepines for initial treatment. As long as the patient is well educated about the possible risks and benefits of the treatment he should be able to exercise his autonomy.

     


    Tumeric- a natural cox-2 inhibitor?

    Recently, due to the massive recall of the incredibly popular drug Vioxx, many patients have expressed their concerns about other potential side effects that perhaps have not yet been discovered about the other cox-2 inhibitors. In many cases, patients have become reluctant to try other drugs that are in the same family as Vioxx, and have instead opted for the more traditional NSAIDs. For most, the change in treatment has been well tolerated, however for others, the side effects from non-selective NSAIDs including gastric ulcers has forced them to stop treatment. Curious as to what else could be done for these patients, I decided to do some research and across an interesting fact- "Tumeric is a natural cox-2 inhibitor!"

    Tumeric, which comes form the root of the Curcuma longa (a leafy plant in the ginger family), is a popular spice that is extensively used in Indian and Southeast Asian cooking and is what essentially gives curry it's yellow color. Since 600 BC, tumeric has not only been used as a flavoring and a dye, but has also been used for medicinal purposes. Throughout Asia, the spice has been consumed to treat stomach and liver aliments and has also been used externally to heal sores.

    Recently, there has been much interested in tumeric and it's natural abilities as an anti-inflammatory agent. One particular literature study concluded that after the research and review of a large number of studies, tumeric (curcumin) demonstrated to be safe in six human trails and has demonstrated anti-inflammatory activity by inhibition of a number of different molecules that play a role in inflamation, including cox-2.


    Garlic – more than just to keep the vampires away?

    In the clinic this week, I saw many patients concerned about hyperlipidemia and heart disease. Many of them already on appropriate lipid lowering medications, wanted to know what more they could do to maintain their health. One women specifically asked about the benefits of garlic as a supplementation to her normal diet. I had always heard that garlic had a laundry-list of benefits - but this came from my grandmother who also swears by knocking on wood and spitting in the presence of a black cat. So, I decided to do some investigating for myself and this is what I found:

    The use of garlic in medicinal practice is evidenced throughout history. So much so, that garlic is commercially available in a variety of supplementation forms from raw to tablets. Garlic and garlic supplements have been used over the years for hyperlipidemia, antiplatelet and procirculatory effects, anticancer and chemoprotective properties, and for immune-enhancement among others. An article on the Historical Perspective of Garlic and Cardiovascular Disease examines the contradictory results of medicinal garlic use. It discusses studies demonstrating that garlic can normalize plasma lipid levels, increase fibrinoltyic activity, inhibit platelet aggregation, and reduce blood pressure and glucose. However, it also introduces studies that have shown garlic to be entirely ineffective. The article concludes that despite conflicting studies, garlic supplementation does positively contribute to the prevention or delay of cardiovascular disease. As for the scope of medicinal benefits with garlic, more extensive studies are required. 

    Another article examines garlic's function in preventing H. Pylori and other bacterial infections. Some interesting findings include: 1) raw garlic juice was found to have anti-microbial properties against several intestinal bacteria in humans, 2) garlic may be effective in strains of bacteria that demonstrate resistance to antibiotics, and 3) garlic may even prevent toxin production by certain miro-organisms. Because garlic has been shown to work synergistically with antibiotics, the article suggests the need for further study to test whether in combination they may be effective in the eradication of resistant or difficult to treat bacteria.

    Yet another known benefit of garlic, is immune enhancement and anti-tumor effects. The mechanism proposed to explain this effect states that garlic is an antioxidant that stimulates cytochrome P450 and as such can detoxify carcinogens. Furthermore, garlic's function as an immune stimulator may contribute to its effects in inhibiting the growth of cancer and decreasing the risk of malignancy. Unfortunately, the article that I found in support of this was performed as an animal study. However, its significant findings may be an encouragment to begin clinical studies.

    So, in conclusion, grandma may have been right all along. Garlic may indeed have a variety of significant medicinal benefits to decrease morbidity and mortality. As such, the literature supports its use as a supplementation in our current diets. However, although studies have demonstrated its beneficial effects, the literature unanimously agrees that further investigation must be done to support incorporation of garlic as a mainstream medicinal therapy. Nevertheless, it may be worth noting that the garlic we use today on Halloween to keep the vampires away might be useful tomorrow to keep the doctors away.


    Cryotherapy for actinic keratosis

    This past week, a 72 year old man came in for treatment of several actinic keratoses on his ears.  My preceptor used a liquid nitrogen spray to freeze the keratoses and thus kill the precancerous lesions.  As a demonstration of what this process feels like, she froze a small spot on my hand.  Trust me, it stings pretty badly for a while.  Not only can this procedure be painfully, it leaves an area of hypopigmented skin after healing.  I wondered whether there is another treatment method that would be equally effective, but without the pain or potential disfiguration.

    In a review (full text) of various treatment methods for actinic keratosis, cryotherapy with liquid nitrogen spray was considered the gold standard of treatment.  Cure rates for this method were reported to be as high as 98.8%.  The use of topical 5-fluorouracil was considered as an alternative treatment.  Cure rates for this method were as high as 93%, however treatment was highly dependant on patient compliance.  Many patients are unable to tolerate the side effects (burning, pain, and itching at the site of application) and therefore fail to apply the topical cream daily, reducing efficacy.

    study (full text) comparing the therapeutic results of cryotherapy (liquid nitrogen) with the reported results of 5-fluorouracil,  found that the cryotherapy treatment demonstrated superior efficacy in preventing recurence of the lesions.  This study found a 30% recurrence after 3 years with the use of cryotherapy compared to a 75% recurrence after 3 years in a similar study employing 5-fluorouracil.

    Though the initial treatment of actinic keratosis with cryotherapy can be painful, the literature I reviewed suggests this is still the best means to treat this condition.  Take home message- wear your sunscreen!

     


    Osteoarthritis and WATER-exercise???

    Hydrotherapy (exercise in a pool) is said to reduce oedema, initiate pain relief and reduce load and damage on joints.  So is this true?

    Abstract

    Full text

    This single blind, three arm, randomized controlled trial compared hydroptherapy resistance exercise program with a gym based resistance exercise on strength and function in 105 patients >50 yo who have osteoarthritis (OA) of knee and hip.  Both groups had 3 exercise session a week for 6 weeks and at 6 weeks a blinded physiotherapist assessed outcomes (muscle strength dynamometry, 6 min walk test, WOMAC OA Index, SF-12 quality of life, Adelaide Activities Profile, & Arthritis Self-Efficacy Scale). 

    Both gym and hydrotherapy exercise programs improved physical function.  GYM was BETTER at building MUSCLE STRENGTH and HYDROTHERAPY was BETTER for an AEROBIC work out.   The gym is recommended for those who want to improve joint stability and increase shock absorption around affected joint.  For those with very painful joint, hydrotherapy is better because it decreases the burden of weight bearing during exercise.

    The gym program had a higher intensity exercise than recommended by American Geriatrics Society and were NO ADVERSE EFFECTS, NO INCREASE IN SYMPTOMS, NO DISEASE ACCELERATION, NO INCREASE IN PAIN (even in severe OA and with joint replacements).   DO RECOMMEND EXERCISE and a heightened intensity will have increased benefits in muscle strength.

    NO VIOXX?! What do we prescribe now?

    As we as all know Vioxx was recently taken off the market in light of new evidence that found that patients who took the drug had an increased risk for cardiovascular events including heart attacks and strokes. The alarming pattern surfaced halfway through an unrelated 3 year study that was looking at Vioxx and colon polyp prevention. Researchers found that heart attacks and strokes had occurred at a much higher rate among the roughly 1300 volunteers on Vioxx (3.5%) than among the 1300 taking a placebo (1.9%).

    With the exact mechanism of as to why Vioxx causes cardiotoxicty still unknown, patients and physicians alike have been left to wonder if perhaps some of the other drugs that are in the same family as Vioxx are not dangerous as well. Pfizer, the manufacturer of the other two major Cox-2 inhibitors Celebrex and Bextra, have been quick to claim that their products have been thoroughly tested and showed no evidence of any correlation between their products and cardiac damage. However, the company has just announced that in light of this new finding with Vioxx, they will begin another 2 year study of their Cox-2 inhibitors at the beginning of next year.

    When Cox-2 inhibitors were first introduced, they were hailed as a miracle drug because unlike older NSAIDs, they were able to selectively hone in on Cox-2, the enzyme implicated with inflammation, but largely avoid Cox-1, the enzyme which protects the stomach from gastric acids. As for now physicians are left to make the decision of whether to keep their Vioxx patients on another Cox-2 inhibitor or to change them to other NSAIDs such as Naprosyn and Arthrotex, have been around for a long time and are tested and true but many patients have problems with these drugs due to their nonselectively, i.e. stomach ulcers.


    Duct Tape: Use #102
    I've seen several patients, from kids to adults, who had concerns about about the common wart (verruca vulgaris) and how to get rid of them.  Yesterday, one young woman asked about over-the-counter salicylic acid treatments.  My preceptor said they were a good method of getting rid of warts.  I asked, "What about duct tape?" 

    The patients reply, "Are you serious?" 

    My preceptor's response, "Yeah, it has been studied as an effective way to get rid of warts." 

    The mechanism is unknown, but it may involve local irrititation that ramps up the immune system; or that every time you remove the duct tape, you peel away some of the wart.  Either way, it seems to work.  So, I decided to track down the study.

    This  prospective, randomized contolled trial (abstract only; full-text article through AMC Intranet) compared duct tape occlusion therapy to standard cryotherapy in 61 patients aged 3 to 22.  In the 51 patients (25 cyrotherapy, 26 duct tape) who completed the study, it was shown that duct tape occlusion therapy was 85% effective in complete resolution of the wart, versus 60% for cryotherapy (p=0.05; no confidence interval provided).  There is also a critical appraisal (through AMC Intranet) of this study, so you don't have to do it yourself, that shows it is valid and probably generalizable.

    For standard cryotherapy treatment, patients returned to the clinic every 2-3 weeks to have liquid nitrogen applied to their warts.  For duct tape therapy, patients covered the wart with duct tape for 6 days, took off the duct tape overnight, and repeated the cycle for 2 months.  Although effective, the problems with cryotherapy are that it is painful, requires multiple office visits, and thus is expensive and time-consuming.  The only problems with duct tape are minor irritation from the adhesive (unless the patient is allergic), that the tape may fall off (especially on the palms), and cosmetic unattractiveness on the face. 

    I would like to see a comparison of duct tape and salicylic acid treatments, but for now, the winner is: duct tape.  It is cheap and easy, you can do it at home, it doesn't hurt, and, hey, it's duct tape (what can't you do with the stuff?).

    Sucking on some cold-eeze

    Familiar case: Pt with a viral URI looking for antibiotics... reassure the pt it will pass, increase hydration, get some rest, gargle with warm salt water, and treat symptoms with OTC med PRN.  Right? 

    Wait, don't forget about the cold-eeze zinc lozenges.  This randomized, double-blind, placebo controlled study looks at the effects of zinc when given within 24 hours of onset of cold symptoms.  Participants were 100 employees of the Cleveland Clinic who developed cold symptoms within the past 24 hours.  Half received a zinc lozenge every 2 hours while awake and the other half received calcium lactate pentahydrate lozenges (placebo). 

    There was a significant reduction in the zinc group in time for complete resolution of symptoms (median, 4.4d vs 7.6d) and duration of cough (2.0d vs 4.5d), headache (2.0d vs 3.0d), hoarseness (2.0d vs 3.0d), nasal congestion (4.0d vs 6.0d), and sore throat (1.0d vs 3.0d).  There were no significant differences in duration of fever, muscle ache, scratchy throat, and sneezing. 

    Possible adverse effects of zinc include nausea and bad taste (I can attest to the nausea part, may want to stay away from zinc if already nauseated or hungover).

    Mechanism of action is unknown, but possible theories include inhibition of the formation of viral capsid and coat proteins, stabilizing and protecting host cell membranes, and induction of certain chemokines.

    Insomnia

    In the office we saw many patients of all ages who complained of sleep problems ( insomia).  Mainly they complained of not being able to fall sleep, and laying awake fr at least an hour before falling sleep.  Patients are first encouraged to improve their sleep hygiene before considering medications.

    I wanted to look at the effectiveness and the safety of long term use of zolpidem (Ambien).  As you may remember, benzodiazepins (BZ) work on the GABA receptors. They can decrease REM sleep therefore they do not produce quality sleep and  produce tolerance and rebound axiety and insomnia.  In addition daytime performance and cognition are also decreased by BZ.

    Therefore, zolidem and Zaleplon (sonata) are preferred for insomnia since they are selective for BZ type 1 receptors so that they are not effective for treatment of anxiety or seizure disorders. Zolpidem (Ambien) is in the class of imidazopyridines, structurally unrelated to BZDs.
    Zaleplon (Sonata) is in the class of pyrazolopyrimidines, also structurally unrelated to BZD.  The half-life of Zolpidem is 2.5 hrs with a peak at 1.6 hrs, and Zaleplon has a half-life of 0.9-1 hr with a peak of 0.9-1.5hr. 

    Here are some of my findings in terms of how to use and usefulness of Ambien:

    • One study showed that even if it is not taken every night it helps improve sleep latency, number of nighttime awakenings, and increase amount of sleep.  They found no tolerance or rebound insomnia.  I also found other studies to support these findings.  Therefore it is not necessary to take Ambien every night and t s better to perscribe it prn.
    • Study showing That insomniacs have a higher cyclic alternating pattern (CAP) on EEG than controls and that there was a significant decrease in CAP and increase in the quality of sleep with the use f zolpidem.

    Can hip pain be related to alcoholism?

    AA came in for a follow up visit for his hip pain.  He had been suffering from severe hip pain for several months now and the results of his imaging were in.  His scan noted avascular necrosis of the femoral head.  How could a 40 year-old man with no history of trauma or corticosteroid use develop avascular necrosis?  He had no other medical problems and he had never been on meds.  While looking through his chart, I found that he had a history of alcohol abuse.  When I approached my preceptor with this little bit of information, he decided that this was the most likely cause of his condition.  However, I was a little interested to see if alcohol use could really be the cause of avascular necrosis in an otherwise healthy male. 

    In this article, several risk factors for non-traumatic osteonecrosis were explored, including alcoholism.  The authors conducted a review of 524 studies on osteonecrosis.  In one study of 57 patients, 29% of patients were found with alcohol-associated osteonecrosis of the femoral head and 12% with idiopathic osteonecrosis.  Another study compared 112 patients with nontraumatic osteonecrosis of the femoral head and no history of systemic steroid use.  The study found an elevated risk for regular drinkers and a dose-response relationship for alcohol intake.  This article also noted another study showing that patients with alcohol-induced osteonecrosis are significantly older than patients with idiopathic osteonecrosis, are usually men (97%), and present with collapsed femoral heads.  How can drinking a six-pack a day possibly cause my patient to develop avascular necrosis, you may ask...   Well, alcohol appears to compromise blood flow through fat embolization or fat hypertrophy.  This can cause cell death by its direct toxic effect on osteocytes and other marrow elements.       

    This case showed me the importance of exploring the risk factors for our patients disorders.  Only then will we be able to gain better diagnostic skills and hopefully help our patients by early detection.      


    Does glucosamine chondroitin relieve arthritic pain?

    Mrs. Jones, a 60 year old woman, came to the office complaining of arthritic pain.  She recieves corticosteroid shots in her knees every three months.  The shots relieve the pain for two months.  She wanted the doctor to prescribe an arthritis medication for the last month until time for another shot, because she was in intense pain.  The doctor ran out of the door and returned with a bottle of Glucosamine Chondroitin.  Dr. Emeny described the supplement as a miracle drug.  The doctor had been taking it for a herniataed disc.  She told the patient that there was a woman who had so much arthritic pain that she could hardly walk.  After taking the supplement for two months the patient could run five miles?

    I found this article in The Lancet, which completed a double-blind placebo study that researched the effects of Glucosamine Chondroitin on osteoarthritis.  The symptoms of pain and decreased function improved by 20-25%.  The supplement was found to decreased the progression of osteoarthritis.  At this time the mechanism of action is unknown.


    Lower your Cholesterol with Cinnamon?

    Early last week we had a 52 year old women who came in with a history of high cholesterol.  She was taking Lipitor, which was managing her cholesterol well, but she really didn't like taking the medication.  She ate a healthy diet and excercised regularly, but that didn't help lower her cholesterol.  She just had a genetic predisposition for high cholesterol.  She came into the office and said she had heard half a teaspoon of cinnamon a day can help lower cholesterol.  I had never heard of this, but my preceptor said he had heard of this.  He didn't feel very optimistic about her trying this, but we decided to conduct an experiment of our own since our patient did not like taking Lipitor.  We drew blood from her that visit to get a lipid panel, and then starting that day she would stop taking Lipitor and start taking half a teaspoon of cinnamon a day, and we would then take another lipid panel measurements her next visit.

    I was curious to see what literature was out there concerning cinnamon and cholesterol.  A lot of the hype about cinnamon came from a study done by Tufts University, which found that cinnamon not only lowered total cholesterol, and LDL it also lowered triglycerides and glucose levels.  As noted in this article the research on cinnamon hasn't been as rigorous as the research on statins.

    Some other studies supporting cinnamon is this article, which shows the multiple benefits of cinnamon in lowering glucose in type 2 diabetes as well as lowering cholesterol.  This is another article which explains the biochemistry behind how cinnamon works to lower cholesterol.

    I think there isn't any harm in trying cinnamon with someone who has high cholesterol.  Although, it is still to early to use cinnamon as a substitute for statins. 


    How accurate is the urine dipstick test when determining whether to treat?

    I hurriedly gave my preceptors my visually-interpreted results of the urine dipstick test of the 9-month-old pregnant young woman whom I had just examined. A decision was quickly made to treat the patient for bacteriuria because as my preceptor said, "she is symptomatic and the urine is positive (1+) for nitrates." The attending that day said that it was imperative to treat in this situation in order to prevent a UTI. Patterson et. al. state that "the prevalence of asymptomatic bacteriuria is 4-7% in pregnancy, when it can progress to symptomatic UTI, postpartum UTI or pyelonephritis." [Patterson et. al., Detection, significance & therapy of bacteriuria in pregnancy. Update in the managed health care era, Inf. Dis Clin N Am 1997; 11:593-608] "Untreated bacteriuria during pregnancy has been shown to be associated with low birth weight and premature delivery." [Romero et. al., Meta-analysis of the relationship between asymptomatic bacteriuria and preterm delivery / low birthweight, Obstet Gynecol 1989; 73:576]  The resident proceeded to give the patient the script for the antibiotic she should take right away. Results of a urine culture were not yet available. I wondered about the reliability of the urine dipstick test reult when coming to such a decision to treat in this case.

    I found an article which helped to me to understand why family practitioners might place so much imoprtance on the urine dipstick test. This article is actually a meta-analysis summarizing the available evidence in this regard which has been compiled from 70 studies performed during the last decade (1990-1999). The 70 studies come from 18 countries and are published in 7 languages. Inclusion and exclusion criteria were specified in the selection of studies. Inclusion criteria were as follows: publications selected had to be centered on the diagnosis of bacteriuria or UTIs, had to investigate the use of the dipstick tests for nitrites and/or leukocyte esterase, and had to present emprirical data. 3 reviewers worked independently to assess the methodological quality of chosen articles. Potential sources of heterogeneity, such as setting, level of care, population sampled and urine collection & analysis procedures, were taken into consideration. Data on sensitivity and specificity were drawn from each of the studies and were combined after being subjected to natural logarithmic transformation.

    Results of the meta-analysis suggest that overall, the test for nitrites had its highest accuracy in certain populations, namely, pregnant women, urology patients and elderly people. In elderly patients alone, the test for nitrites reached a high sensitivity and, whereas in pregnant women sensitivity was lowest. This was consistent with the results reported by Patterson (see above citation). The pre-test probability was also shown to be higher in family medicine or primary care studies as compared to studies done in hospitals. This was attributed to the fact that family doctors use the dipstick more to diagnose an infection once clinical signs and symptoms are noted, whereas doctors in the hospital use the test to screen patients to makre sure they don't have an infection.  


    Vigilance

    Last week I encountered a 65-year-old man being seen in the office for hypernatremia discovered during a routine physical.  His sodium level was 165 mEq/L, distressing due to the high mortality rate of this extreme of an increase.  The man had no complaints and no associated physical findings.  However, this man had the mental capacity of a 7-year-old and was previously diagnosed with schizophrenia, being treated with Lithium among other agents.  Given the narrow therapeutic range for Lithium and the fact that this patient was also being treated with loop diuretics, which can increase the risk of lithium toxicity, we began to think about Nephrogenic Diabetes Insipidus secondary to lithium therapy.

     

    This case illustrates how very important it is for us to be aware of the issues associated with the drugs we are prescribing especially in cases where our patients cannot be advocates for themselves through voicing complaints.

     

    As this study points out, many problems develop from chronic usage of lithium.  As such it is an iatrogenic illness, occurring in patients such as the one I encountered who have identifiable clinical risk factors: nephrogenic diabetes insipidus, older age and impaired renal function.  It is important for us to be aware of all effects of therapies we initiate as well as all the interactions possible.


    My mole is getting darker! – Is it melanoma?

    A patient in his mid-30's came to the clinic to get a mole in his back checked.  He was very concerned that the mole has been getting bigger and darker in the past several months and that it might be melanoma.  Although my preceptor said it was likely to be a benign nevus based on the ABCD criteria, she could not rule out melanoma completely.  She scheduled for dissection and biopsy of the lesion on the following day to rule out melanoma.

    The ABCD criteria for diagnosis of melanoma refers to checking Asymmetry, Border, Color and Diameter of a suspicious skin lesion or nevus:   

    A - Asymmetry (melanoma lesion more likely to be asymmetric)

    B - Border irregularity (melanoma more likely to have irregular borders)

    C - Color (melanoma more likely to be very dark black or blue and have variation in color than a benign mole, which more often is uniform in color and light tan or brown)

    D - Diameter (mole <6 mm in diameter usually benign)

    According to this study which examined 195 cutaneous pigmented lesions in 186 patients, the ABCD criteria can serve as a valid clinical guide to distinguish melanoma from benign nevi.  The investigators imaged the lesions using telespectrophotometric system which included a special camera that provided imaging of moles at different wavelengths.  Next, they analyzed images of melanoma and other lesions according to the ABCD criteria.  The result showed that all the variables(ABCD) showed statistically significant (p < 0.05) differences between melanoma and other lesions; especially, reflectance(C) showed the most significant difference between the two groups[melanoma vs. others], p < 0.0001.

    Another study investigated enlargement(E) of the lesion as one of the screening criteria for melanomas.  They found adding ‘E' to the ABCD criteria made the screening more sensitive and more specific.

    However, a recent study demonstrated that the ABCD criteria are not absolute.  As much as 38% of melanomas they studied were less than or equal to 6 mm in diameter; it may be necessary to biopsy a lesion to rule out melanoma, even if it doesn't fit into the ABCD criteria.

    Ribavirin for Hep C??
     A 55 yo female contracted Hep C via IV drug use.  She is currently on interferon treatment.  I discussed this case with my preceptor who told me that interferon is the only validated treatment for HepC  and that 50% of patient s don't respond to it.  There must be research going on to find new treatment methods for nonresponders. This is one study I came across. 

    In this randomized trial, ribavirin was added to interferon in hopes of a better response in those who did not respond to interferon alone. The following two regimens compared were: (1)6 MU alpha-interferon for 6 months and 3MU, both doses given 3x/week subcutaneously and (2)1.2 grams of  ribavirin for 2 months followed by the 12 month course of interferon as described above, during the first 2 months there is concurrent treatment with ribavirin.  Improved aminotransferase activity was more commonly found in the combo group (53%) than in the interferon group (26%).  HCV RNA was undetectable by PCR in 25% of those in the combo group and only in 7.7% of those in the interferon group.  The histopathology (necrosis and degeneration) of those in the combo group was improved in comparison to the interferon group (69% vs. 36%).  However, none of these improvements were maintained. 
    It seems that adding ribavirin to interferon treatment is unnecessary based on this study.  Although initial findings are encouraging, most of the improvements are not sustained past 6 months post treatment.  Ribavirin costs $$$20,000/ 4 months.  I would say stick to interferon. 


    Slow Down That Delivery!

    The Family Practice doctors in Nebraska tend to deliver a lot of babies compared to back east. In fact, the F.P. residents are required to "catch" a certain number of babies during their Ob/Gyn rotation. One morning, labor progressed faster than expected and the baby's head was halfway out of the mother by the time my resident and I arrived. The rest of the baby followed quickly, leaving a 2nd degree laceration through the vaginal wall. The resident told me afterward that fast deliveries are more likely to cause vaginal tearing, and that normally he would have applied pressure on the baby's head during delivery to ease it out more slowly.

    Unfortunately, there does not appear to be much (if any) research on preventing vaginal tears by delivering a baby slowly. Part of the reason for this is that a prominent doctor in the 1920's declared that the 2nd stage of labor, where the mother "pushes" was harmful to both mother and child. Thus for many years the standard of care was to perform an episiotomy and use forceps to help speed delivery. (There is LOTS of evidence that episiotomies actually cause worse tears and higher morbidity than natural tears, but that should be the subject of another POEM... :-) )

    An article on Dr. Spock's website (http://www.drspock.com/article/0,1510,4453,00.html) claims that "the best protection [against tearing during childbirth] is a slow, controlled birth, with a practitioner experienced in avoiding laceration and episiotomy." Another article by an M.D. (http://www.fisher-price.com/us/babygear/article.asp?c=bg_labor&artid=114712) also claimes that a slow delivery, especially in a woman with pliable skin, allows the perenium to stretch around the baby's head without tearing. Likewise, the antidotal evidence of midwives (related on http://www.gentlebirth.org/archives/perinealProtection.html) seems to support a slow, controlled delivery to protect against tearing during birth.

     

    Clinical commentary in Obstetrics & Gynecology (http://www.acog.org/from_home/publications/green_journal/wrapper.cfm?document=2000/ong11779fla.htm) claims that "forces that might inhibit physicians from practicing evidence-based techniques of obstetric delivery include time pressures, malpractice concerns, lack of experience with slow perineal stretching, and an interventionist practice pattern." Furthermore, it states that "there is no evidence that delivery practices that avoid perineal trauma are correlated with low Apgar scores, birth trauma, or cerebral palsy." The article then sites evidence from a large cohort of women (18,940 deliveries between 1981 and 1984) which found no change in neonatal outcomes despite an increase in the length of the second stage. (Reynolds JL, Yudkin PL. Changes in the management of labour: 1. Length and management of the second stage. CMAJ 1987;136:1041-1045, http://www.cmaj.ca/cgi/content/abstract/136/10/1041). The Ob & Gyn article also sites two more large studies along the same lines.

    The bottom line on all this seems to be that the practice of obstetrics is changing, with fewer episiotomies being performed in favor of a slower, more natural childbirth. There are many benefits to surviving labor & delivery with an intact perenium, including a faster recovery, and we should investigate methods of doing so more thouroughly as a profession.

    Metformin for PREVENTION of diabetes mellitus???

    Sure, metformin is one of the premiere oral hypoglycemic drugs used to treat diabetes mellitus, Type 2 (DM 2).  It is effective only in the presence of insulin and its major effects are to decrease hepatic glucose output and increase insulin action.  As a result of the improvement in glycemic control, serum insulin concentrations decline slightly.  But when an obese teenager came in to clinic and was found to have a fasting glucose of 111 mg/dL, I was surprised that the resident would prescribe metformin.  According to diagnostic criteria for diabetes, this patient did not have diabetes.  The resident explained that the metformin therapy could help prevent the progression to diabetes.  I decided to investigate. 

    The Diabetes Prevention Program (DPP) was a major, randomized clinical trial aimed at discovering whether either diet and exercise or the oral diabetes drug metformin (Glucophage) could prevent or delay the onset of type 2 diabetes in high-risk individuals with elevated fasting plasma glucose concentrations and impaired glucose tolerance (IGT).  The answer is yes.  In fact, the DPP found that over the 3 years of the study, diet and exercise sharply reduced the chances that a person with IGT would develop diabetes when compared to placebo. Metformin also reduced risk, although less dramatically.  The incidence of diabetes was 11.0, 7.8, and 4.8 cases per 100 person-years in the placebo, metformin, and lifestyle groups, respectively.  The DPP resolved these questions so quickly that, on the advice of an external monitoring board, the program was halted a year early.

    Since diabetes is a main cause of kidney failure, limb amputation, heart disease and new-onset blindness in American adults, it makes sense to try to prevent diabetes.  Patients, who are increased risk of developing diabetes, include: 

  • overweight
  • 45 years old or older
  • a parent, brother, or sister with diabetes
  • family background is African American, American Indian, Asian American, Hispanic American/Latino, or Pacific Islander
  • gestational diabetes or gave birth to at least one baby weighing more than 9 pounds
  • blood pressure is 140/90 or higher
  • HDL cholesterol is 35 or lower, or triglyceride level is 250 or higher
  • fairly inactive
  • Therefore, these patients may benefit from metformin therapy to prevent progression to diabetes, as was seen with the DPP study.


    I can't fall asleep

    I've noticed that a lot of the elderly patients at the clinic are complaining of problems falling asleep.  Some were newly diagnosed and others were previously diagnosed, but had stopped taking their medications and are interested in restarting their sleeping pills.  In every case, the resident or attending did not hesitate to prescribe sleeping pills, always Ambien, without exploring other options. 

    Cognitive Behavioral Therapy (CBT) is one method that has been reported to be effective in relieving insomnia or problems falling asleep.  CBT incorporates the recognition  and challenging of negative thinking prior to falling asleep and changing behaviors that prolongs falling asleep, these are referred to as sleep hygiene.  One study concluded that CBT is more effective than sleeping pills.  Patients responded faster and the effects were longer lasting than sleeping pills.  Patients who were treated with CBT were falling asleep without problems a year later as opposed to those who were treated with sleeping pills and had to experience their side effects and also rebound insomnia upon withdrawal of the pills.  One main disadvantage of CBT is that it is widely unavailable to patients.

    I tried to find other ways of safely and naturally treating insomnia and basically all natural methods that involved no meds recommended changing sleep behaviors, or changing the atmosphere of your bedroom.  Relaxation is key.  There are other natural medications available.  They are inexpensive, but they aren't regulated.

    I think that doctors shouldn't be so quick to prescribe meds as soon as the patients hint at sleeping problems.  More time should be spent exploring other natural treatments, then use meds as a last resort. 


    Treatment of nongenital warts

    Background:  Warts are benign proliferations of skin and mucosa caused by human papilloma viruses (HPV). Currently, more than 150 types of HPV have been identified. Certain HPV types tend to occur at particular anatomic sites; however, warts of any HPV type may occur at any site. The primary clinical manifestations of HPV include common warts, genital warts, flat warts, and deep palmoplantar warts (myrmecia). Warts are transmitted by direct or indirect contact, and predisposing factors include disruption to the normal epithelial barrier. Treatment can be difficult, with frequent failures and recurrences; however, many warts resolve spontaneously within a few years.

    Question: To assess the effects of different local treatments for cutaneous, non-genital warts in healthy people.

    Answer: Simple topical treatments containing salicylic acid have a therapeutic effect.

    Discussion: Systematic review of fifty randomized controlled trials for efficacy of local treatments for cutaneous warts to clear warts and adverse effects such as irritation, pain, and blistering. The best available evidence was for simple topical treatments containing salicylic acid, which are clearly better than placebo. Data pooled from six placebo-controlled trials show a cure rate of 144/191 (75%) compared with 89/185 (48%) in controls, odds ratio 3.91 (95% confidence interval 2.40 to 6.36), random effects model. Most of the bigger trials of cryotherapy studied different regimens rather than comparing cryotherapy with other treatments or placebo. Pooled data from two small trials that included cryotherapy and placebo or no treatment, showed no significant difference in cure rates. In two trials comparing cryotherapy with salicylic acid and one comparing duct tape with cryotherapy no significant difference in efficacy was demonstrated. There was no consistent evidence for the effectiveness of intralesional bleomycin. There was some evidence for the efficacy of dinitrochlorobenzene, a potent contact sensitizer. Pooled data from two small studies comparing dinitrochlorobenzene with placebo showed cure rates of 32/40 (80%) and 15/40 (38%) respectively, odds ratio 6.67 (95% confidence interval 2.44 to 18.23), random effects model. Only limited evidence was found for the efficacy of topical 5-fluorouracil, intralesional interferons and photodynamic therapy. Bleomycin, dinitrochlorobenzene, 5-fluorouracil, interferons and photodynamic therapy are potentially hazardous or toxic treatments.

    Conclusion: The treatment of cutaneous warts lacks the valid evidence to come up with the logical bases for treatment. Placebo preparations had a significant positive outcome in treating cutaneous warts. There is certainly evidence that simple topical treatments containing salicylic acid have a therapeutic effect. There is less evidence for the efficacy of cryotherapy and some evidence that it is only of equivalent efficacy to simpler, safer treatments. Dinitrochlorobenzene appears to be effective but there were no statistically significant differences when compared with the safer, simpler and cheaper topical treatments containing salicylic acid. The benefits and risks of 5-fluorouracil, bleomycin, interferons and photodynamic therapy remain to be determined.


    Steroid injections for shoulder pain

    Shoulder pain is a common complaint of many patients presenting to their primary care physician.  The etiology of this pain is varied, including tendinitis, impingement syndromes, and trauma (rotator cuff tears, dislocations, etc.).  In this past week, I saw 3 people who presented with shoulder pain from different causes and each received the same treatment, a steroid injection to the joint space around the most tender region of the shoulder.  According to my preceptor, this is a common means with which to deal with shoulder pain in the primary care setting.  However, my text pointed out that the evidence for the efficacy of steroid injections in most cases of shoulder pain was sparse at best.  Plus, steroid injections are not without risk, having the potential to introduce an infection to the joint, or inadvertently injecting a tendon, resulting in atrophy and possible rupture.  So what is the evidence to support corticosteroid injections for shoulder pain?

    A Cochrane Review of corticosteroid injections for shoulder pain looked at 26 studies comparing steroid injections with physiotherapy for treatment and relief of shoulder pain.  In general, this review did little to either refute or support the use of steroid injection, as the studies reviewed were small and employed very different methodologies.

    Another study of 207 patients with unilateral shoulder pain presenting to their primary physician sought to compare physiotherapy with corticosteroid joint injections.  This study found that both treatment methods attained a similar outcome with a successful outcome in 60% of the physiotherapy patients and 53% of those receiving the injections.  The difference between these results was not statistically significant.  The injection group, however, required more follow-up with their physicians, increasing their workload.

    A third study had results that conflicted with those of the above study and review.  Here, 77% of patients receiving a steroid injection had favorable outcomes compared with 46% of those undergoing physiotherapy.

    What should we make of all this?  It is obvious that while steroid injections have become a staple in the treatment of shoulder pain in the primary care setting, little definitive evidence exists to support its use.  More studies are needed to elucidate whether this should be the primary means of treatment.


    Acupuncture for back pain???

    A common complaint seen at the clinic this week was back pain. Although the age presentation varied from young adults to the elderly, the setting from acute to chronic, and the etiology from work injury, to sports injury, to "I don't know what happened...but my back is killing me." - the requests were all the same "doctor, please do something to ease my pain." I was surprised to find that for many of these patients, my preceptor recommended a course of acupuncture therapy. Like the patients, I too wanted to know - can acupuncture really help relieve back pain? So, after some searching, this is what I found. 

    In support of acupuncture, I found a blinded placebo-controlled study that randomized patients to receive acupuncture (either manual or electro-stimulation) or placebo for the treatment of low back pain. Patients received one treatment a week for eight weeks and an additional two treatments in a follow-up six months later. Assessments done at one and six months found an improvement in 14-16 of 34 patients in the acupuncture group and only 2 of 16 in the placebo group. Criteria for assessing improvement included a decrease in intensity of pain, a decrease in the need for analgesics, as well as a significant improvement in return to work and quality of sleep. Thus, the authors concluded that acupuncture is effective in the long-term pain relief of nociceptive low back pain.

    Still not entirely convinced, I continued my search until I found an article that hit a bit closer to home as it discussed acupuncture as a treatment for the high incidence of back pain (over 80%) in nurses. Surprisingly this back pain was anything but benign as it resulted in the loss of more than 150 million working days per year. Furthermore, many of these nurses did not respond to prior attempts for treatment using medication, bed rest, physical therapy, chiropractics, and surgery. The article gives a nice summary of the philosophy of acupuncture and Chinese Medicine as well as references to various studies that demonstrate the effectiveness of acupuncture in the treatment of back pain.   

    In conclusion, although the verdict may still be out for many of you, the literature I found seems to support the use of acupuncture for the treatment of nociceptive back pain. Just something to keep in mind for the future, when after hours and hours of being on our feet, our posture begins to sag and our backs beg for some relief. Before you reach for those NSAIDs or decide to tough it out and tolerate, you might just want to give acupuncture a try.

    My Child is Bouncing off the Wall!!!!

    Whether we will become Pediatricians, Family Practice Doctors, Psychiatrists or perhaps even others, we will undoubtedly hear these words come out of parents' mouths..."(insert name) just won't sit still and never pays attention!!....I don't know what else to do!" For many of these kids, discipline is the main problem, for others, however, a true diagnosis of ADHD may be in order. For many of these parents, Ritalin, the mainstay of ADD/ADHD treatment for years is the obvious answer, for others, however, the idea of their child being on an amphetamine-like stimulant day after day leaves something to be desired...could that something be Strattera?...The first non-stimulant medication approved for the treatment of ADHD. This article makes a preliminary comparison between Ritalin (methylphenidate) and Strattera (atomoxetine) in treatment of ADHD in school-aged children.

    After an evaluation and drug washout period, patients were randomized to open-label treatment with either Ritalin or Strattera for 10 weeks, with weekly visits.

    Clinical Assessment: The primary measure of symptom response was the investigator-rated ADHD RS, an 18-item scale in which each item corresponds to one of the 18 DSM-IV symptom criteria for ADHD, based on an interview with a parent. A parent-rated version of the ADHD RS, identical in structure and content to the investigator-rated version, was also administered.

     A previous study has shown that Strattera is efficacious and well tolerated. The results presented here provide preliminary evidence concerning the magnitude of response compared withRitalin. Among children with DSM-IV-defined ADHD, similar reductions in ADHD symptoms were seen in both the Strattera and Ritalin treatment groups. For both drugs, inattentive and hyperactive-impulsive symptoms responded to treatment, and parent reports were consistent with investigator assessments.

    Overall, this study was well-done. One important limitation however, is that the study was not double-blinded. Therefore, parental and investigator expectations may have altered the results. I would still definitely use Strattera in my practice, especially for those parents who are adamantly opposed to having their children treated on an ongoing basis with stimulant medication.

    Glucosamine for osteoarthritis?
    A 62-year old woman was seen in the office the other day wondering what she could do for the arthritis in her knees.  She's been taking NSAIDs, but they're not really doing much.  Imagine my surprise when my preceptor told her that the only thing that's been shown to slow the progression of osteoarthritis is glucosamine.  I've heard all the anecdotal stuff before, and seeing as how my knee seems to be going down the same road, I figured I'd check it out to prove it to myself. 

    This randomized, placebo-controlled study showed that glucosamine sulfate significantly slows osteoarthritis progression, as assessed by joint space width and the WOMAC Index, in postmenopausal women (as was my patient).  Of the women who completed the trial, joint space width in the glucosamine group increased by 0.17mm (versus a narrowing of 0.37mm in the placebo group), and there was an improvement in the WOMAC Index in terms of pain and function (the important part for the patient), but not stiffness (versus a worsening in all three parameters in the placebo group).  Acetominophen and NSAID use was allowed for rescue pain relief, and physical therapy was allowed if the participants were following a stable regimen; there was no significant baseline difference between the two groups.  This study combined the results from two studies (click here and here for abstracts) that independently showed similar results. 

    Well, I'm sort of convinced (not totally because this research was partly supported by the manufacturer of the glucosamine used).  Also, it seems to be pretty safe (remember, first do no harm), so if the patient wants to, why not try it if nothing else really works?  I may try it myself in hopes of halting the impending arthritis in my knee. 

    One thing to keep in mind: most of the studies out there used Dona(TM) crystalline glucosamine sulfate from Rotta Pharmaceuticals (Wall, NJ).  Different formulations may have different results.  Oh yeah, it's pretty expensive too (and not covered by insurance).

    Flu Vaccine Crisis

    This week in the office, we've seen many patients who are asking for flu vaccines in light of the shortage that has ocurred due to the contamination of Chiron's supply.

    This puts us in a tough spot.  We bought our vaccine from Aventis.  So we have enough for now - but it may not last.

    The CDC has released spankin-new guidelines that show who should get a flu vaccine and who shouldn't:

    Everyone in this group should seek vaccination:

    • People 65 years of age and older
    • Children ages 6 months to 23 months
    • Adults and children 2 years of age and older with chronic lung or heart disorders including heart disease and asthma
    • Pregnant women
    • Adults and children 2 years of age and older with chronic metabolic diseases (including diabetes), kidney diseases, blood disorders (such as sickle cell anemia), or weakened immune systems, including persons with HIV/AIDS
    • Children and teenagers, 6 months to 18 years of age, who take aspirin daily
    • Residents of nursing homes and other chronic-care facilities
    • Household members and out-of-home caregivers of infants under the age of 6 months (Children under the age of 6 months cannot be vaccinated.)
    • Healthcare workers who provide direct, hands-on care to patients

    So many of the healthy adults who are seeking vaccine do not qualify for a flu shot.

    Yes - you've seen it advertised, so I know you're thinking about that new cool stuff called Flumist.  Does it work?

    Well, yes.  But it's awfully expensive.  

    In our practice, we have implemented the CDC guidelines and will not be giving out our vaccine to people who are supposed to get it.  Flumist remains an alternative for healhty adults and kids over five.
