Parasites
I saw a patient recently for parasites. I get a sinking feeling when I see that diagnosis on the schedule, as it rarely means a real parasite. The great Pacific NW is mostly parasite free, so either it is a traveler or someone with delusions of parasitism. The latter comes in two forms: the classic form and Morgellons. Neither are likely to...
Science vs Homeopathic Pseudoscience
Science is a philosophy, a technology, and an institution. It is a human endeavor- our collective attempt to understand the world around us, not something that exists solely in the abstract. All of these aspects of science have be progressing over the past decades and centuries, as we refine our concepts of what science is and how it works, as we develop...
Echinacea for Cold and Flu
Echinacea continues to be a popular herbal product, used primarily for treating and preventing colds and flus. Sales were estimated at $132 million in the US alone in 2009, an increase of 7% over the previous year. Reports of major negative clinical trials have had only a modest and temporary effect on the popularity and sale of this herb, contradicting claims that...
The Cargo Cult of Acupuncture
Bloodletting, of course, was a major aim of early vessel therapy and is frequently described in the Su wen.1 Paul U Unschuld “Cargo cult” is a metaphor that describes the act of imitating an activity or a practice without any insight into the underlying principles. In the literal sense, it refers to a magico-religious practice observed in tribal societies, where the members...
NEJM and Acupuncture: Even the best can publish nonsense.
I realize that the New England Journal of Medicine (NEJM) review of acupuncture has already been covered by Drs. Gorski and Novella. But my ego knows no bounds; so I thought I would add my two cents, especially since this review, more than any paper I have read, generates a deep sense on betrayal. There was a time when I believed my...
Acupuncture Pseudoscience in the New England Journal of Medicine
Here is the conclusion quoted from a recent New England Journal of Medicine (NEJM) review article on acupuncture for back pain: As noted above, the most recent wellpowered clinical trials of acupuncture for chronic low back pain showed that sham acupuncture was as effective as real acupuncture. The simplest explanation of such findings is that the specific therapeutic effects of acupuncture, if...
Terrible Anti-Vaccine Study, Terrible Reporting
One of my goals in writing for this blog is to educate the general public about how to evaluate a scientific study, specifically medical studies. New studies are being reported in the press all the time, and the analysis provided by your average journalist leaves much to be desired. Generally, they fail to put the study into context, often get the bottom...
The genetics of autism
Autism and autism spectrum disorders (ASDs) actually represent a rather large continuum of conditions that range from very severe neurodevelopmental delay and abnormalities to the relatively mild. In severe cases, the child is nonverbal and displays a fairly well-characterized set of behaviors, including repetitive behaviors such as “stimming” (for example, hand flapping, making sounds, head rolling, and body rocking.), restricted behavior and...
Potential New Mechanism of Pain Relief Discovered
The development of drugs and other treatments for specific symptoms or conditions relies heavily on either serendipity (the chance finding of a beneficial effect) or on an understanding of underlying mechanisms. In pain, for example, there are limited ways in which we can block pain signals – such as activating opiate receptors or inhibiting prostaglandins. There are only so many ways in...
Breastfeeding Is Good but Maybe Not THAT Good
An article entitled “The Burden of Suboptimal Breastfeeding in the United States: A Pediatric Cost Analysis,” by Bartick and Reinhold, was published in Pediatrics 2010 April 5. According to this news report, it showed that 900 babies’ lives and billions of dollars could be saved every year in the U.S. if we could get 90% of mothers to breastfeed for at least 6 months....
