Toxic myths about vaccines
Antivaccine activists would have you believe that vaccines are loaded with "toxins" and are therefore dangerous. While there are some chemicals that sound scary in some vaccines, they dose makes the poison, and at the tiny amounts used in vaccines none of these "toxins" are harmful.
Prior Probability: The Dirty Little Secret of “Evidence-Based Alternative Medicine”
This is actually the second entry in this series;† the first was Part V of the Homeopathy and Evidence-Based Medicine series, which began the discussion of why Evidence-Based Medicine (EBM) is not up to the task of evaluating highly implausible claims. That discussion made the point that EBM favors equivocal clinical trial data over basic science, even if the latter is both...
Alternative Medicine, and the Internet
When I think back to my own ‘discovery’ of the skeptical movement, it grew out of my experience watching the James Randi Secrets of the Psychics NOVA special. After being enthralled with the special (and with several Randi books already in my library) I sought Mr. Randi out on the Internet. In chat rooms, blogs, forums and skeptical conferences such as TAM...
Another Acupuncture Study – On Heartburn
Patients with heartburn are often diagnosed with GERD (gastroesophageal reflux disease) and treated with a drug called a proton pump inhibitor (PPI) to reduce stomach acid production. It is pretty effective, but it doesn’t always work. When it doesn’t, standard practice has been to double the dose of PPI. Doubling the dose only improves symptoms in 20-25%. Most patients who fail the...
Hype over science: Does acupuncture really improve the chances of success for in vitro fertilization?
There it was on Friday greeting me on the ABC News website: “Study: Acupuncture May Boost Pregnancy” in bold blue letters, with the title of the webpage being “Needles Help You Become Pregnant.” The story began: It sounds far-fetched sticking needles in women to help them become pregnant but a scientific review suggests that acupuncture might improve the odds of conceiving if...
Antioxidant Hype and Reality
A new study by lead author Shelly Gray and published in the latest issue of the Journal for the American Geriatric Society, found no effect from taking Vitamin C or E, either alone or in combination, on the risk of dementia or Alzheimer’s disease after 5.5 years. Vitamins C and E were chosen because they both have significant antioxidant activity, and so...
The National Center for Complementary and Alternative Medicine (NCCAM): Your tax dollars hard at work
What’s an advocate of evidence- and science-based medicine to think about the National Center for Complementary and Alternative Medicine, better known by its abbrevation NCCAM? As I’ve pointed out before, I used to be somewhat of a supporter of NCCAM. I really did, back when I was more naïve and idealistic. Indeed, as I mentioned before, when I first read Wally Sampson’s...
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...
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 Ethics of Deception in Medicine
A recent study published in the Journal of General Internal Medicine and featured in a Time Magazine article, indicated that of 466 academic physicians in the Chicago area, 45% indicated that they have prescribed a placebo for a patient. This has sparked a discussion of the ethics of prescribing placebos in particular and deception in general in medicine. A placebo is a...
