Is the Annual Physical Unnecessary?

I was approached by The Wall Street Journal to write an article for their Big Issues in Health Care debate series. The subject was “Is the annual physical unnecessary?” I was to take the “yes” side and an internist was to take the “no” side. I wrote the following article. The editor wrote me a couple of times with questions. The internist...

Questioning the Evidence for Breastfeeding

Six years ago I wrote about the evidence for breastfeeding. I questioned an article that claimed 900 babies’ lives could be saved every year in the US if 90% of mothers breastfed for at least 6 months. I didn’t think that was true, but I did think the evidence supported the claim that breastfeeding was clearly better for babies. Now I’m not...

When Headaches Are a Pain in the Neck: Spinal Manipulation vs. Mobilization for Cervicogenic Headache

NOTE: Today we offer a double feature on the treatment of cervicogenic headache. My article is about a study that compared manipulation to mobilization; it is followed by retired chiropractor Sam Homola’s guest article on manipulation for cervicogenic headache. The two posts complement each other and also complement my post from last week on the possible risk of stroke with neck manipulation....

Chiropractic and Stroke: No Evidence for Causation But Still Reason for Concern

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 causation. My colleagues and I...

Carotid Artery Stenosis: Surgery, Stent, or Nonsurgical Stroke Prevention?

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 flows in an artery). It can cause symptoms, including transient ischemic attacks...

Testing Testosterone Treatments

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 any of a long laundry list of vague symptoms. Anti-aging clinics promote...

Cargo Cult Psychology

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 Astray: Cargo Cult in Science and Therapy, that is certain to ruffle a lot of feathers....

Statin Side Effects

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 are still disputable issues....

The Essential Role of Regulation In Human Health and In Ecology: The Serengeti Rules

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 determines the uncontrolled growth...

As good a source of stem cells as any chiropractor.

Stem Cells and Chiropractic

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 Technology Takes Joint Treatment to the Next Level.” It said stem cell treatments could heal and regenerate...
