Treating The Common Cold

For the last week I have had a cold. I usually get one each winter. I have two kids in school and they bring home a lot of viruses. I also work in a hospital, which tends (for some reason) to have lots of sick people. Although this year I think I caught my cold while traveling.  I’m almost over it now,...

The Flu Vaccine and Narcolepsy

Preliminary evidence has linked the flu vaccine to narcolepsy in several Scandinavian countries. Is the link real? What could be the mechanism?

The Safety Checklist

During my recent stint covering the Neuro ICU I noticed for the first time a checklist posted above each patient bed. The checklist covered the steps to undergo whenever performing an invasive procedure on the patient. I was glad to see that the checklist phenomenon had penetrated my hospital, although the implementation of safety checklists is far from complete. A recent study...

Statins – The Cochrane Review

A recent Cochrane review of the use of cholesterol-lowering statin drugs in primary prevention has sparked some controversy.  The controversy is not so much over what the data says, but in what conclusions to draw from the data. Statin drugs have been surrounded by controversy for a number of reasons. On the one hand they demonstrably lower cholesterol, and the evidence has...

Dr. Oz Embraces Joseph Mercola

At SBM we are highly in favor of physicians and scientists interfacing with the public, using mainstream and new media to promote the public understanding of science and to explain the modern practice of medicine. Now that Dr. Dean Edell has retired (unfortunately) from his radio show, it is probable that Dr. Mehmet Oz has the highest exposure of any media physician....

1023 2011

The 1023 campaign is a UK based organization whose purpose is to raise awareness of the actual claims of homeopathy. The name is a reference to Avogadro’s number (6.02214179×10^23), which is the number of atoms or molecules of a substance in one unit called a mole. This is an important basic concept in chemistry, for it means that there are a finite...

Obesity Denial

It seems that for every established science there is an ideological group who is motivated to deny it. Denialism is a thriving pseudoscience and affects any issue with the slightest political or social implications. Sometimes, even easily verifiable facts can be denied, as people seem willing to make up their own facts as needed. Denialists have an easy job – to spread...

CAM Use by Brain Tumor Patients

A recent article in the journal Neurology reports the results of an observational study regarding the use of so-called complementary and alternative medicine (CAM) by patients with an incurable brain glioma. They found that 40% of patients sought some type of CAM treatment. These results are in line with prior surveys, but require closer inspection. The study defined CAM as: Complementary therapy...

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...

Acupuncture and the Hazard of Nonsense

A recent study published in the Archives of Opthalmology compare patching of one eye vs acupuncture in the treatment of amblyopia in older children, and finds positive results from acupuncture. The study, and its press, are a good example of the hazards of studying highly implausible modalities. First let’s dissect the study itself – from the abstract: In a single-center randomized controlled...
