Phthalates and BPA: Of Mice and Men
Is your soup poisoning you? In a recent study subjects who ate canned vegetable soup had markedly increased levels of BPA in their urine compared to those who ate freshly prepared soup. We are constantly bombarded with alarmist warnings about the dangerous chemicals in the products we use. Especially BPA (Bisphenol A) and phthalates. Beware plastic bottles! Beware rubber ducks! And now,...
Update on CPSOs Draft Policy
Four months ago David Gorski wrote about the College of Physicians and Surgeons of Ontario’s (CPSO) draft policy on “non-allopathic” medicine. He pointed out: It’s obvious from the wishy-washy approach to the scientific basis of medicine, the waffle words when it comes to whether an “allopathic” physician should support “non-allopathic” therapies, and the apparently inadvertent use of language favored by quacks that there...
Random Flu Thoughts
Influenza is a serious disease (not an upset tummy). The vaccine is an imperfect, yet still valuable tool in preventing deaths due to influenza. Get your 'flu shot!
Milk Thistle and Mushroom Poisoning
If you’ve been fortunate to live in the parts of the US that were soggier than usually as of late – or unfortunate enough to have had flooding from hurricanes and tropical storms – then you’ve be noticing a tremendous burst of mushrooms. For mycologists – mushroom enthusiasts – there are two classic chestnuts: “There are old mushroom collectors and bold mushrooms...

Does Weight Matter?
Determining the net health effects of independent factors can be tricky, especially when those factors cannot be controlled for in experimental studies. For things like body mass index (BMI) we must rely on observational data and triangulate with multiple studies to isolate the contributions from BMI. But it can be done. The data, however, are likely to be complex and noisy, and...
The College of Physicians and Surgeons of Ontario’s muddled draft policy on “non-allopathic” medicine
Detroit is my hometown, and three and a half years ago, after nearly twenty years away wandering between residency, graduate school, fellowship, and my first academic job, I found myself back in Detroit minted as surgical faculty at Wayne State University and practicing and doing research at the Barbara Ann Karmanos Cancer Institute. One thing that I had forgotten about while I...
On the Orwellian language and bad science of the anti-vaccine movement: “SmartVax” versus “MaxVax”?
If there’s one thing that’s true of the human race, it’s that when it comes to persuasion language is has power. Words have power. Just ask the advertising industry or politicians, who rely on their skills manipulating language to persuade for their very livelihood and authority. In the specific bailiwick of this blog, Science-Based Medicine, many of us have spent considerable verbiage...
Dummy Medicines, Dummy Doctors, and a Dummy Degree, Part 1: a Curious Editorial Choice for the New England Journal of Medicine
Background This post concerns the recent article in the New England Journal of Medicine (NEJM) titled “Active Albuterol or Placebo, Sham Acupuncture, or No Intervention in Asthma.” It was ably reviewed by Dr. Gorski on Monday, so I will merely summarize its findings: of the three interventions used—inhaled albuterol (a bronchodilator), a placebo inhaler designed to mimic albuterol, or ‘sham acupuncture’—only albuterol...
Behavior and Public Health – To Nudge or Legislate
As health care costs rise and great attention is being paid to the health care system in many countries (perhaps especially the US), the debate is heating up over how to improve public health. Many health problems are greatly increased by the lifestyle choices individuals make – smoking, weight control, and exercise to name a few. The problem is that it is...
Anti-vaccine propaganda in The Baltimore Sun
The hypothesis that vaccines cause autism has been about as thoroughly falsified through research as any health hypothesis can be. Even if, by bending over backward into a back-breaking contortionist pose to be “open-minded”, some people will concede that there’s still a bit of room for reasonable doubt about whether there is no link between vaccines and autism in “susceptible” populations, there...
