Science And The Game Of 20 Questions

An audience member at a recent NYC Skeptics meeting asked me how I handled conflict surrounding strongly held beliefs that are not supported by conclusive evidence. As a dentist, he argued, he often witnessed professionals touting procedure A over procedure B as the “best way” to do X, when in reality there are no controlled clinical trials comparing A and B. “How...

Does the Flu Vaccine Increase Hospitalizations?

The Centers for Disease Control (CDC) currently recommends that children 6 month to 18 years old receive an annual flu vaccine. There are two types of flu vaccines used in the US: a live attenuated virus (LAIV) and a trivalent inactivated virus (TIV) vaccine. Both are safe and effective  – while efficacy varies from year to year, they are 70-90% effective in...

Another Kind of Evolutionary Medicine

Last month I wrote about a book on evolutionary medicine that I could not recommend. Now I’ve found one I can recommend. Marlene Zuk, an evolutionary biologist at the University of California, Riverside, has written a delightful book entitled Riddled with Life: Friendly Worms, Ladybug Sex, and the Parasites That Make Us Who We Are. She describes how our parasites and diseases...

Chemical castration for autism: After three years, the mainstream media finally notices

We’ve written a lot about anti-vaccine zealotry on this blog, as Steve and I take a particular interest in this particular form of dangerous pseudoscience for a number of reasons. One reason, of course, is that the activities of antivaccine groups like Generation Rescue and its spokesmodel since 2007 (Jenny McCarthy, a frequent topic on this blog) have started to frighten parents...

Homeopathy and Sepsis

It had once been suggested in the comments section of the blog that homeopathy is useful in the treatment of diseases that are not self limited. Homeopathy is effective therapy for diseases that do not get better on their own, that homeopathy has a real effect on real diseases. One example given was for the treatment of sepsis. “Frass M, Linkesch, M,...

Hostility Towards Scientists And Jenny McCarthy’s Latest Video

I’ve been fairly quiet about Jenny McCarthy’s campaign against childhood vaccinations, partly because Dr. David Gorski has covered the issue so thoroughly already, and partly because of my “do not engage” policy relating to the deeply irrational (i.e. there’s no winning an argument with “crazy.”) But this week I was filled with a renewed sense of urgency regarding the anti-vaccinationist movement for...

Acupuncture and Back Pain – Part II

Last week I discussed a clinical trial comparing standardized acupuncture, individualized acupuncture, placebo-acupuncture, and usual care. In that discussion I emphasized the comparison between the three acupuncture groups, which did not show any difference in outcome. These results are consistent with the overall acupuncture literature, which shows in the better controlled trials that it does not matter where you stick the needles...

Raw deal: Got diarrhea?

I recently saw a 14 year old girl in my office with a 2 day history of severe abdominal cramps, bloody diarrhea, and fever. Her mother had similar symptoms as did several other members of her household and some family friends. After considerable discomfort, everyone recovered within a few days. The child’s stool culture grew a bacterium called Campylobacter. Campylobacter is a nasty...

AA is Faith-Based, Not Evidence-Based

Alcoholics Anonymous is the most widely used treatment for alcoholism. It is mandated by the courts, accepted by mainstream medicine, and required by insurance companies. AA is generally assumed to be the most effective treatment for alcoholism, or at least “an” effective treatment. That assumption is wrong. We hear about a few success stories, but not about the many failures. AA’s own...

The case of chemotherapy refusenik Daniel Hauser

I’ve written before about clinical trials as one place where “the rubber hits the road,” so to speak regarding the interface between science-based medicine and actual medical practice. Another critical place where an equal amount of rubber hits an equal amount of road is how the medical system and the law deal with the medical care of minors. In the vast majority...
