I have written two posts in the past on proper disposal of unused medications, and I have always been mindful of the medicines as a source of environmental water pollution. This past week the American Chemical Society reminded (head-slapped me) that topical medications are a source of environmental water pollution from their active pharmaceutical ingredients (APIs). Yes, the simple act of bathing washes hormones, antibiotics, and other pharmaceuticals down the drain into the water supply.
Ilene Ruhoy, M.D., Ph.D. and colleague Christian Daughton, Ph.D. looked at potential alternative routes for the entry into the environment by way of bathing, showering, and laundering. These routes may be important for certain APIs found in medications that are applied topically to the skin — creams, lotions, ointments, gels, and skin patches. These APIs include steroids (such as cortisone and testosterone), acne medicine, antimicrobials, narcotics, and other substances. Read more »

A new study published in PLOS Biology looks at the potential magnitude and effect of publication bias in animal trials. Essentially, the authors conclude that there is a significant file drawer effect –- failure to publish negative studies -– with animal studies and this impacts the translation of animal research to human clinical trials.
SBM is greatly concerned with the technology of medical science. On one level, the methods of individual studies need to be closely analyzed for rigor and bias. But we also go to great pains to dispel the myth that individual studies can tell us much about the practice of medicine.
Reliable conclusions come from interpreting the literature as a whole, and not just individual studies. Further, the whole of the literature is greater than the sum of individual studies –- there are patterns and effects in the literature itself that need to be considered.
One big effect is the file drawer effect, or publication bias –- the tendency to publish positive studies more than negative studies. A study showing that a treatment works or has potential is often seen as doing more for the reputation of a journal and the careers of the scientists than negative studies. So studies with no measurable effect tend to languish unpublished. Read more »

Is healthcare a right or a privilege? Depending on how you view this determines how you feel about the recent healthcare reform which was signed by President Obama. As a doctor, I firmly believe that having healthcare is a right.
As a nation, we agree that individuals should be accountable for their actions. People often argue that those who are reckless with their bodies by ingesting chemicals via cigarettes or drug use and who subsequently develop cancers shouldn’t be subsidized by others’ insurance premiums as the latter group works hard at staying healthy by exercising, maintaining a healthy weight, and eating generous portions of fruits and vegetables. Some how it isn’t fair. Unfortunately, life and good health aren’t quite that easy or predictable. Read more »

“Am I having a heart attack?” From the files of the strange and unusual comes this self-test kit for myocardial infarction, otherwise known as a heart attack.
For the lay people out there, a heart attack occurs when bloodflow to the heart muscle stops, usually because of a blockage in the arteries around the heart (coronary arteries). (It’s what happened to Bill Clinton, although his heart muscle didn’t die, as it likely had collateral bloodflow from other arteries.) When bloodflow stops, the heart muscle dies. When the heart muscle cells die, they release compounds into the bloodstream which can then be detected on blood draws.
That is the basis for detecting a heart attack by drawing blood. There are some compounds that are specific to the heart, such as troponins that will only go up when the heart muscle is dying. Other enzymes, such as the CK go up with any muscle damage, including the heart.
That is the basis of this new self-test kit for heart attack testing from China Sky One Medical that tries to answer the “Am I having a heart attack?” question at home. It was approved in China in 2007 and recently received European Union clearance as well. Read more »

It’s very generous of Sanolfi-Aventis’s marketing department to make this offer for me to serve as an “advisor” for dronedarone (Multaq), but seriously–I was a bit skeptical that they wanted my “feedback on the reasons for and against utlilization of Multaq® in the appropriate patient as well as to understand communication and educational needs with regard to Multaq® and the atrial fibrillation state in general.”
Where were they when the drug launched? Might it be because this drug hasn’t quite been the blockbuster they’d hoped for?
But, of course, I’d never be swayed to use more of this drug by such important consulting work. No, really.
P.S. Sanolfi-Aventis marketers: Please update your prescriber database with my correct workplace.
