The War on Salt
The problem with the Western diet is not one of deficiency, but one of excess. We get too much of a good thing – too many calories, too much of the wrong kind of fat, and too much salt. As a result obesity, diabetes, and hypertension are growing health problems. There also does not appear to be an easy solution – voluntary...
Acupuncture for Hot Flashes
In the most recent issue of The Journal of clinical Oncology is a study comparing acupuncture to Effexor in the treatment of vasomotor symptoms (hot flashes) in women with breast cancer who cannot take hormone replacement therapy. The study found that the two treatments are equivalent, with longer duration and fewer side effects from acupuncture. However, the study is designed as a...
Ginkgo biloba – No Effect
Another one bites the dust. The National Center for Complementary and Alternative Medicine (NCCAM) is generally a waste of taxpayer money, but they have sponsored several well-designed large trials of popular herbal supplements. And one by one these studies have shown these popular products, such as echinacea for the common cold, to be ineffective. To add to the list, published in JAMA...
Lithium for ALS – Angioplasty for MS
Peter Lipson reported Monday about new research suggesting that multiple sclerosis may be caused by venous blockage. He correctly characterized some of the hype surrounding this story as “irrational exuberance.” This is a phenomenon all too common in the media – taking the preliminary research of an individual or group (always presented as a maverick) and declaring it a “stunning breakthrough,” combined...
Communicating with the Locked-In
Facilitated communication is exploitation supported by false hope and good intentions. Brain-machine interfaces are progressing with agonizing slowness, but offer true potential in actually permitting paralyzed people to communicate and even regain movement.
Evidence in Medicine: Experimental Studies
Several weeks ago I wrote the first in a brief series of posts discussing the different types of evidence used in medicine. In that post I discussed the role of correlation in determining cause and effect. In this post I will discuss the basic features of an experimental study, which can sere as a check-list in evaluating the quality of a clinical...
Early Intervention for Autism
Many parents of children with autism have expressed to me their dismay that the anti-vaccine lobby is sucking all the oxygen out of the room for autism awareness. They feel that just being a parent of a child with autism makes others assume that they are anti-vaccine. They also worry that resources and attention are being diverted from promising legitimate research because...
Man in Coma 23 Years – Is He Really Conscious?
Belgian citizen Rob Houben has been noncommunicative for 23 years. Has he suddenly gained the ability to communicate?
Evidence in Medicine: Correlation and Causation
There are two general approaches to subverting science-based medicine (SBM): anti-science and pseudoscience. Anti-scientific approaches are any that seek to undermine science as the determinant of the standard of care, often overtly advocating for spiritual or subjectively-based standards. Some attack the validity of science itself, usually with post-modernist philosophy. Pseudoscientific proponents, on the other hand, praise science, they just do it wrong....
