Glucosamine Update: A New Study and a New Product

When I recently wrote about glucosamine, I discussed the evidence up through the New England Journal of Medicine study of 2006, which I thought was a pretty definitive study showing that neither glucosamine, chondroitin or a combination of the two was more effective than placebo.  Subsequent studies have continued to fuel the controversy. One 2007 study showed that glucosamine sulfate was better than placebo for knee osteoarthritis.  Another 2007 study showed...

Antibiotics for Sinusitis

You’re a patient. That cold just isn’t getting better and you have purulent drainage from your nose, and your face hurts and your teeth hurt. You probably have sinusitis, right? You go to a doctor to get an antibiotic. You’re a doctor. Deep down, you know there’s a good chance the patient has a self-resolving condition.  You’d rather not do x-rays on every patient who...

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...

The International Network of Cholesterol Skeptics

There is an organization that calls itself The International Network of Cholesterol Skeptics (THINCS). Its members “thinc” they are smarter than the average doctor. They “thinc” that cholesterol has nothing to do with cardiovascular disease and that we have been deluded into waging a “cholesterol campaign” for which the scientific evidence is non-existent. They say, “What we all oppose is that animal...

Does Glucosamine Really Work?

Glucosamine and chondroitin, used separately or together, are among the more popular diet supplements. They are used widely for osteoarthritis, especially of the knee, and have been better studied than most other diet supplements. But do they really work? The journal of my medical specialty, American Family Physician, recently published an article about the use of dietary supplements in osteoarthritis. They gave...

Akavar 20/50 and Truth in Advertising

Over the last few months, I have had a truly surreal experience. It started when I noticed a two-page full color spread in TV Guide magazine advertising a product called Akavar 20/50. It contained the same claims that so many bogus weight loss products do: eat all you want and still lose weight. What attracted my interest was their highlighted statement: “We...

No-Touch Chiropractic

Some time ago, I learned that a Seattle chiropractor, Johanna Hoeller, had been featured on a local TV newsmagazine show. She was so proud of the segment that she had it posted on her web page for all to see. Unfortunately it is no longer there, so I’ll have to tell you what it showed. She demonstrated her techniques on-camera. She put...

Snake Oil Science

For my first blog entry, I wanted to write about something important, and I couldn’t think of anything more important than a recent book by R. Barker Bausell: Snake Oil Science: The Truth About Complementary and Alternative Medicine. If you want to understand how medical research works, if you want to know what can lead patients and scientists to false conclusions, if...
