Can neck manipulation (by chiropractors or by other practitioners) cause strokes? Many of us think it can, but definitive proof is lacking. A recently published study looked at the available evidence. A systematic review found a small association between stroke and chiropractic care but concluded that the association was spurious and that there was no evidence for
One treatment for carotid artery stenosis: stent placement The carotid artery in the neck is a common site of atherosclerosis. As plaque builds up, it leaves less room for blood flow and can cause strokes through clotting or embolization. Carotid stenosis is defined as a greater than 70% narrowing of the lumen (the space through which the blood
Whatever is in this water, it isn’t testosterone Ponce de Leon is said to have been looking for the Fountain of Youth when he explored Florida. That’s only a myth. Now there’s a new myth, that testosterone supplements are a Fountain of Youth for aging men. Men are urged to get their testosterone levels checked if they have
A cargo cult pseudo airplane. How much of psychology is like this? Last year I reviewed Tomasz Witkowski and Maciej Zatonski’s book Psychology Gone Wrong where they pointed out that many of psychology’s accepted beliefs and therapies were not based on good evidence. Now Witkowski has written a new book, to be published later this year, Psychology Led
A recent article in The New England Journal of Medicine by Andrew L. Mammen, MD, PhD, reviewed statin-associated myopathies. Reading his article prompted me to revisit the subject of statin side effects. It can no longer be disputed that statins statistically benefit patients who have cardiovascular disease or who are at high risk of cardiovascular disease. But there
The doubling time for E.coli bacteria is 20 minutes. With uncontrolled growth, it would take a mere two days for the weight of bacteria to equal the weight of the Earth. What rules determine the actual numbers of bacteria? Why is the world green; why don’t insects eat all the leaves? How does the body maintain homeostasis? What
As good a source of stem cells as any chiropractor. My local newspaper is a constant source of topics to blog about. It regularly features ads for untested dietary supplements and for chiropractors who offer non-chiropractic treatments and don’t identify themselves as chiropractors. Recently, a full-page ad for NW Pain Relief Centers trumpeted “Stem Cell
Alice Dreger has written a delightful, breezy, and slightly terrifying book on activism gone bad, and how it impacted scientists just trying to uncover facts and truth. Highly recommended! It dates back at least to Galileo. A scientist finds evidence that contradicts a cherished popular belief. Instead of a rational examination of his evidence, he
When I was pregnant, I obediently took the iron pills and prenatal vitamins prescribed by my obstetrician. And I prescribed them for every pregnant patient I took care of as a family physician. I never questioned the practice. It seemed intuitively obvious that it was a good thing; we know pregnancy makes extra nutritional demands
In a recent post, Dr. Gorski criticized two articles by Jo Marchant on placebos and alternative medicine. He mentioned that she had a book coming out and suggested I might want to review it. The title is Cure: A Journey into the Science of Mind Over Body. I don’t know of any evidence that the mind has ever
