Evidence in Medicine: Experimental Studies
Several weeks ago I wrote the first in a brief series of posts discussing the different types of evidence used in medicine. In that post I discussed the role of correlation in determining cause and effect. In this post I will discuss the basic features of an experimental study, which can sere as a check-list in evaluating the quality of a clinical...
Endocrine disruptors—the one true cause?
A common theme in alternative medicine is the “One True Cause of All Disease”. Aside from the pitiable naivete, it’s implausible that “acidic diet”, liver flukes, colonic debris, the Lyme spirochete, or any other problem—real or imagined—can cause “all disease” (in addition to the fact that most of these ideas are intrinsically mutually exclusive). One of the popular new ideas in this...
Lose those holiday pounds
Lose weight without diet or exercise? I guess that leaves cancer. –David Letterman. It is the day after Thanksgiving, and I have probably eaten enough calories to support the average family for at least three days. I am hesitant to comment on what my actual weight may be, but others have not been so reticent about discussing my appearance over at RDCT....
A temporary reprieve from legislative madness
While doctor visits for influenza-like illnesses seem to be trending downward again, and “swine flu” is becoming old news, I’d like to draw attention to an H1N1 story that has received very little coverage by the mainstream media. Doctors in several states can now protect their most vulnerable patients from the H1N1 virus without worrying about breaking the law. In order to save lives, several states...
Ontario naturopathic prescribing proposal is bad medicine
Two weeks ago, Canadian Skeptics United published on their Skeptic North site a piece by an Ontario pharmacist criticizing a proposal by the province to grant limited prescribing rights to naturopaths. The essay, which was reprinted in the National Post on Tuesday, outlines the intellectual and practical conundrum presented by allowing those with education that diverges from science-based practices to prescribe drugs....

Why Universal Hepatitis B Vaccination Isn’t Quite Universal
I am just a parent with some questions about vaccine safety and was happy to find your website. I have noticed that the Scandinavian countries do not routinely recommend HepB vaccination unless the mother is a known carrier. I did not see this addressed anywhere on your website and I hope you or one of your colleagues might consider discussing the reasons...
Does C-section increase the rate of neonatal death?
It is a potentially devastating indictment of the rising C-section rate. Most midwifery and “natural” childbirth websites claim that elective C-section triples the rate of neonatal mortality. Mainstream web sites like Feministing.com, and newspapers like The New York Times have repeated the claim. There’s just one problem. It’s not true. The claim originated with the paper Infant and Neonatal Mortality for Primary...

Recombinant Human Antithrombin – Milking Nanny Goats for Big Bucks
Antithrombin deficiency is a hereditary disease causing low levels or defects of antithrombin, a blood protein required for controlling clot formation. Patients are at risk of blood clots, organ damage, and death. They usually have to take oral anticoagulant drugs like warfarin for life. During high-risk procedures like surgery or childbirth, oral anticoagulants must be discontinued to minimize the chance of bleeding...
Medical Marijuana: are we ready?
Cannabis has been used recreationally and medically for centuries. Despite long experience, relatively little is known about the risks and benefits of its use as a medication. A considerable portion of our ignorance can be attributed to government discouragement of cannabis research. Searching the NIH website brings up many studies of both cannabis abuse and cannabis as a therapeutic agent, but most...
What’s in the water at waterbirth?
Water birth is dangerous, unnatural, has no benefits, and unlikely, but serious risks. So of course someone is selling it.
