While we frequently on SBM target the worst abuses of science in medicine, it’s important to recognize that doing rigorous science is complex and mainstream scientists often fall short of the ideal. In fact, one of the advantages of exploring pseudoscience in medicine is developing a sensitive detector for errors in logic, method, and analysis. Many of the errors we point out in so-called “alternative” medicine also crop up elsewhere in medicine – although usually to a much less degree.
It is not uncommon, for example, for a paper to fail to adjust for multiple analysis – if you compare many variables you have to take that into consideration when doing the statistical analysis, otherwise the probability of a chance correlation will be increased.
I discussed just last week on NeuroLogica the misapplication of meta-analysis – in this case to the question of whether or not CCSVI correlates with multiple sclerosis. I find this very common in the literature, essentially a failure to Read more »

In one of the stranger research projects I’ve encountered in awhile, French scientists reported on why in the sport of discus throwing, athletes tend to feel more dizzy than those who hammer throw.
Whether discus or hammer throwing, both require spinning on part of the athlete before letting the discus/hammer go for long distances.
59% report dizziness with discus throwing, but none with hammer throwing. Why?
This occurred even among athletes who did both sports eliminating individual susceptibilities to dizziness.
Based on slow-motion video analysis, it was conjectured that Read more »

A study on this topic was presented at the recent American Society of Plastic Surgeons (ASPS) annual conference in Denver. The article is also in the October issue of the Plastic and Reconstructive Surgery journal (reference #2 below).
The article notes that more than 220,000 bariatric procedures are done annually in the United States. This number (IMHO) is likely to increase as these procedures have become an major tool in the treatment of obesity which now affects a third of adults in this country.
Massive weight loss, regardless of whether by bariatric procedure or by diet/exercise, will often leave the individual with excess skin. This excess skin can be both a cosmetic and functional issue for the individual.
Jason Spector, MD and colleagues designed their study to “explore demographic features and patient education regarding body contouring procedures in the bariatric surgery population.”
Their study consisted of Read more »

It’s been more than five years since Henry Mintzberg released the enlightening book ‘Managers, not MBAs’, a well-reasoned criticism of prevailing management education that basically revolves around Master in Business Administration (MBA) programs. Financial crisis was not even in sight but Mintzberg, a professor at McGill University in Montreal and one of the most important guiding lights in the questionable field of management, already pointed out that it was a serious danger for modern organizations to rely on professionals that had just finished their MBAs as the prime source for senior managerial positions.
Mintzberg focused his criticism on two essential aspects. First, most programs are aimed at people with no previous experience or knowledge about organizations and how they look like from the inside… and these same people then storm into companies believing that the real world works exactly as business school taught them it does. The second point is that many of these business schools spread a perverted set of values, such as the hunt for short-term profit, the belief that a good aim justifies any means and the urge to translate all human behaviors into accountable figures (the ‘countophrenia’ depicted by Vincent de Gaulejac in his must-read ‘La Société Malade de la Gestion’).
Then the crisis rose, and many CEOs of the biggest organizations had their share of responsibility for it, as they were enjoying multi-million dollar bonuses while taking their companies to the edge of bankrupcy. Most of them came from the most famous business schools in the world. I have outlined in the past the outrageous conflict of interests of many of these institutions, starting with Harvard, as Charles Ferguson perfectly displayed in his brilliant documentary ‘Inside Job’.
‘Social Science and Medicine’ published in its August issue a very interesting work by Amanda Godall, professor at the IZA Institute for the Study of Labor in Bonn, Germany. Godall’s is the first empirical research on the correlation between hospital results and having MDs in their top managerial positions. Read more »

Though one should always use an EpiPen that is not expired, it is better to use an expired EpiPen to treat anaphylaxis than to do nothing at all.
Some Canadian researchers studied expired EpiPen auto-injectors 1 to 90 months past the expiration date.
What they found was that the older the EpiPen, Read more »
