The Role of Anecdotes in Science-Based Medicine
While attending a lecture by a naturopath at my institution I had the opportunity to ask the following question: given the extreme scientific implausibility of homeopathy, and the overall negative clinical evidence, why do you continue to prescribe homeopathic remedies? The answer, as much as my question, exposed a core difference between scientific and sectarian health care providers. She said, “Because I...
Science by press release: A helmet to fight Alzheimer’s disease?
Recently, I’ve had a number of people bring to my attention a news story that has apparently been sweeping the wire services and showing up in all sorts of venues. It is, on its surface, a story of hope, hope for the millions of elderly (and even the not-so-elderly) who are or will be afflicted by that scourge of the mind, memory,...
Annals of Questionable Evidence: a new study reveals substantial publication bias in trials of anti-depressants
Part IV of the ongoing Homeopathy series will have to wait a day or two, because it is superceded by a recent, comment-worthy publication. Nevertheless, “H series” fans will find here a bit of grist for that mill, too. An important role for this blog is to discuss problems of interpreting data from clinical studies. Academic medicine has committed itself, on the...
Itching and the Imaginary Passenger Brake
The press and government agencies ally to shine a disproportionate amount of publicity on false and improbable medical ideas. (Danger: Congressmen and reporters at work.) The latest was a press release from either the Centers for Disease Control (and prevention? – I’ll get to the “prevention” part later,) or from Kaiser-Permanente Medical Group. Three Bay Area newspapers carried simultaneous articles. The articles...
The infiltration of complementary and alternative medicine (CAM) and “integrative medicine” into academia
A few years back, my co-blogger Wally Sampson wrote a now infamous editorial entitled Why the National Center for Complementary and Alternative Medicine (NCCAM) Should Be Defunded. When I first read it, I must admit, I found it to be a bit harsh and–dare I say?–even close-minded. After all, plausibility aside, I believed at the time that the only way to demonstrate...
Homeopathy and Evidence-Based Medicine: Back to the Future–Part III
“Symptoms,” Continued Part II of this blog† introduced the homeopathic understanding of “symptoms” as they pertain both to “provings” in healthy subjects (now called “homeopathic pathogenic trials” or “HPTs”) and to histories elicited from patients. Hahnemann conflated “symptoms” and every random itch, ache, pain, sniffle, feeling, thought, dream, pimple or other sign, and anything else that might occur to a subject or...
Collision of Incompatibles
Last week’s post was about a recent (October 2007) meeting held at Harvard University on the subject of fascia. The purposes for commenting were several. First, the organizers were partial believers in some forms of “Complementary and Alternative Medicine” (“CAM”), now being called “Integrative” but more realistically called sectarian or anomalous, aberrant medicine. The meeting is another in a long series of...
The Placebo Effect
Recently the Federal Trade Commission went after the makers of the Q-Ray Ionized Bracelet for their claims that their device was a cure for chronic pain. Last week Seventh Circuit judge Frank Easterbrook handed down his opinion on the company’s appeal, writing that the company was guilty of fraud and ordering them to pay 16 million dollars in fines. One of the...
Homeopathy and Evidence-Based Medicine: Back to the Future – Part II
Part I of this blog† summarized the origin of homeopathy, invented in 1790 by Samuel Christian Hahnemann. It discussed Hahnemann’s first two “homœopathic laws of nature,” similia similibus curantur (like cures like) and the “law of infinitesimals,” and showed that his rationales for each have long been refuted. Hahnemann proclaimed a third doctrine, the “law of psora” [“itch”], said by him to...
Snake Oil Science
For my first blog entry, I wanted to write about something important, and I couldn’t think of anything more important than a recent book by R. Barker Bausell: Snake Oil Science: The Truth About Complementary and Alternative Medicine. If you want to understand how medical research works, if you want to know what can lead patients and scientists to false conclusions, if...
