Genetic Testing: Does Knowing Risk of Disease Make a Difference?

The complete sequencing of the human genome by the Human Genome Project was a remarkable accomplishment and a cause for celebration. Several companies including 23andMe, Navigenics, and deCODE have capitalized on that scientific achievement by offering genomic testing directly to the public. They promise more than they can deliver, and consumers don’t understand the limitations of the test results. The subject has...

The ROCA Screening Test for Ovarian Cancer: Not Ready for Prime Time

Ovarian cancer is relatively rare but deadly. The lifetime risk of ovarian cancer is 1.5% compared to 12% for breast cancer, but it is the 5th most common cause of cancer death for women. Since the ovaries are hidden deep in the pelvis and the symptoms of ovarian cancer are non-specific, the cancer is often advanced by the time it is diagnosed...

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...

Functional medicine: The ultimate misnomer in the world of integrative medicine

Functional medicine. It sounds so...scientific and reasonable. It's anything but. In fact, functional medicine combines the worst features of conventional medicine with a heapin' helpin' of quackery.

Regulating CAM Aussie Style

CAM proponents view National Health Interview Surveys recording the supposed popularity of CAM, an amorphous conflation of anything from conventional medical advice to mythical methods, as an invitation to unleash even more unproven remedies on the public. My interpretation is quite different. I see the same figures as proof that we are doing too little to protect the public from pseudoscience. In...

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...

Lyme Testing

I hate those oh hell moments. I was up way too late last night, but who can pass up the opportunity to see Patti Smith playing Horses (and more) for the 40th anniversary of the album. Only 44? Behind the Eagles? No way. I would nudge it up a few more spaces. Hard to believe I was 18 when that album came...

Legislative Alchemy 2015: Another losing season for CAM practitioners

One of the main, but perhaps underappreciated, reasons quackery thrives in the United States is that the states legalize it by licensing practitioners of pseudoscience as health care providers. These practitioners are placed under the regulatory jurisdiction of, well, themselves. I call the whole deplorable process Legislative Alchemy, and you can see all posts on the topic here. It gives practitioners an...

Colonoscopy: More Misinformation from Mercola

Joseph Mercola, D.O., runs the website mercola.com which is full of misinformation, advocates all kinds of questionable alternative treatments including homeopathy, and discourages vaccination and other aspects of conventional medicine. Like Dr. Oz and Andrew Weil, he is more dangerous than easily recognizable quacks in that he combines some good medical information with egregious misinformation, and readers who know he is right...
