The claim that Gardasil causes premature ovarian failure: Ideology, not science
It’s amazing how, to antivaccine activists, it just so happens that a vaccine that targets a sexually transmitted virus must also destroy a girl’s ovaries. It must be a coincidence, right?
Are the recommended childhood vaccine schedules evidence-based?
We write about vaccines a lot here at SBM, and for a very good reason. Of all the medical interventions devised by the brains of humans, arguably vaccines have saved more lives and prevented more disability than any other medical treatment. When it comes to infectious disease, vaccination is the ultimate in preventive medicine, at least for diseases for which vaccines can...
What naturopaths say to each other when they think no one’s listening, part 2
It’s said that the true test of a person’s character is what he or she does and says when no one is watching. When it comes to science and medicine, naturopaths fail that test of character. Again. Antivaccine views and quackery? It's all there, with a dollop of paranoia.
Zika virus, microcephaly, and calls to bring back DDT (Rachel Carson revisionism edition)
In response to the Zika virus threat, predictably the same group of anti-environmentalists are urging that we bring back DDT and "Spray, baby, spray!" To make their questionable case, they overstate the benefits of DDT, downplay its risks, and engage in some major historical revisionism regarding the legacy of Rachel Carson.
Did chiropractic neck manipulation kill Katie May?
Well, we’re back. Yes, after having our WordPress database somehow borked to the point where no new posts could be added and no existing posts could be edited since Friday, Science-Based Medicine is back in business—finally! As a result, some of you might have seen this post elsewhere, as it was considered to be somewhat time-sensitive, and I didn’t want to delay,...
When antivaccine pseudoscience isn’t enough, Bill Maher fawns over Charlie Sheen’s HIV quack
I know I must be getting older because of Friday nights. After a long, hard week (and, during grant season, in anticipation of a long, hard weekend of grant writing), it’s not infrequent that my wife and I order pizza, plant ourselves in front of the TV, and end up asleep before 10 or 11 PM. Usually, a few hours later, between...
Science-based medicine versus the Flint water crisis
One aspect of science-based medicine that is not covered frequently on this blog, aside from vaccines and antivaccine pseudoscience, but perhaps should be, is the intersection of SBM and public health. Unfortunately, living as I do in southeast Michigan right now, I’ve been on the receiving end of an inescapable lesson in what happens when the government fails in its mission to...
The cost of repealing mandatory motorcycle helmet laws
It’s a seldom mentioned aspect of my professional history that I used to do a lot of trauma surgery in my youth. I did my residency at a program that included a county hospital with a busy trauma program where I saw quite a bit of vehicular carnage and an urban hospital (which has since closed) where I saw a fair amount...
Is “harnessing the power of placebo” worthwhile to treat anything?
We frequently write about placebo effects here on Science-Based Medicine. The reason is simple. They are an important topic in medicine and, at least as importantly, understanding placebo effects is critical to understanding the exaggerated claims of advocates of “complementary and alternative medicine” (CAM), now more frequently called “integrative medicine” (i.e., integrating pseudoscience with science). Over the years, I (and, of course,...
You’ve been diagnosed with breast cancer. How soon do you need treatment?
Timely surgery for breast cancer is obviously better than delaying surgery, but how long can a patient safely wait for surgery once diagnosed. Because a randomized controlled clinical trial to answer this question would be unethical, this has been a difficult question to answer. Fortunately, a new study provides an estimate of how much of a delay it takes before outcomes start...
