Placebo Effects Revisited
In the Wall Street Journal last week was a particularly bad article by Melinda Beck about acupuncture. While there was token skepticism (by Edzard Ernst, of course, who is the media’s go-to expert for CAM), the article credulously reported the marketing hype of acupuncture proponents. Toward the end of the article Beck admits that “some critics” claim that acupuncture provides nothing more...
Acupuncture for Depression
One of the basic principles of science-based medicine is that a single study rarely tells us much about any complex topic. Reliable conclusions are derived from an assessment of basic science (i.e prior probability or plausibility) and a pattern of effects across multiple clinical trials. However the mainstream media generally report each study as if it is a breakthrough or the definitive...
Homeopathy Gets a Reality Check in the UK
The House of Commons Science and Technology Committee (STC) has released a report, Evidence Check 2: Homeopathy, in which they recommend that the NHS stop funding homeopathy. The report is a rare commodity – a thoroughly science-based political document. The committee went beyond simply stating that homeopathy does not work, and revealed impressive insight into the ethical, practical, and scientific problems caused...
Energy Healing In Maryland
I had an interesting conversation with a reporter today. She called me to get a “medical/skeptical” counterpoint for an article she is preparing on energy healing. Although I don’t know if she’ll faithfully represent what I had to say, we had an entertaining exchange and so I decided to capture the essence of it here. I’m curious to see which parts of...
Be careful what you wish for, Dr. Dossey, you just might get it
If there’s one thing about the so-called “complementary and alternative medicine” (CAM) movement that I’ve emphasized time and time again, it’s that its adherents have a definite love-hate relationship with science. They hate it because it is the single greatest threat to their beliefs system and the pseudoscience that underlies it. At the same time, they crave the legitimacy that science confers....
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...
All Medicines Are Poison!
That’s the title of a new book by Melvin H. Kirschner, M.D. When I first saw the title, I expected a polemic against conventional medicine. The first line of the Preface reassured me: “Everything we do has a risk-benefit ratio.” Dr. Kirschner took the title from his first pharmacology lecture in medical school. The professor said “I am here to teach you...
AFP Promotes Acupuncture
I subscribe to American Family Physician, the peer-reviewed journal of the American Academy of Family Physicians. It emphasizes evidence-based medicine and most articles include a table showing strength of evidence ratings for key recommendations for practice. Lately, its scientific rigor has been slipping. I have complained to the editor about several articles whose recommendations were not based on the best science, and...
Placebo is not what you think it is
If I read one more crappy article about placebos, something’s gotta give, and it’s gonna be my head or my desk. Wired magazine has a new article entitled, “Placebos Are Getting More Effective. Drugmakers Are Desperate to Know Why.” Frequent readers of skeptical and medical blogs will spot the first problem: the insanely nonsensical claim that “placebos are getting better”. This not...
The Microbial Metagenome
First some background. I was first directed to the Marshall protocol by a reader who wondered about the information the found on the web. So I went to the web and looked at the available information, much as any patient would, and discussed what I found there. I have subsequently been lead to believe that none of the information on the website...
