Fake Treatments for Fake Illnesses
I wrote previously on NeuroLogica blog about Morgellons disease. Both Peter Lipson and Wallace Sampson have also covered this interesting syndrome here on SBM. Briefly, sufferers of this dubious syndrome believe they have foreign material exuding from their skin, causing chronic itching and sores. The evidence suggests that in truth they suffer from something akin to delusional parasitosis – the false belief...
Interpreting the Medical Literature
The science in science-based medicine includes all of science, but relies most heavily on the biomedical literature – published studies that collectively represent our scientific medical knowledge. The scientific basis of medicine is only as good as this body of knowledge and the manner in which it is interpreted and put into practice. We often discuss on this blog how to evaluate...
Calories, Thermodynamics, and Weight
When arguing against a specific scientific claim it is always desirable to be able to say that the claim violates an established law of science. Creationists attempt this with their argument that evolution violates the second law of thermodynamics (it doesn’t). The temptation is that such arguments are short and pithy, they seem conclusive, and they avoid the need to wade through...
Nobel for HIV Discoverers
The Nobel Prize in Medicine was awarded this week to two French virologists, Françoise Barré-Sinoussi and Luc A. Montagnier, for discovering the AIDS causing virus, the Human Immunodeficiency Virus (HIV). They will share half the prize of 1.4 million dollars, the other half going to three Dr. Harald zur Hausen for discovering the human papilloma virus and its relation to cervical cancer....
Cognitive Dissonance at the New York Times
Humans have the very odd ability to hold contradictory, even mutually exclusive, ideas in their brains at the same time. There are two basic processes at work to make this possible. The first is compartmentalization – the ideas are simply kept separate. They are trains on different tracks that never cross. We can switch from to the other, but they never crash...
Acupuncture for Hot Flashes – Or, Why So Many Worthless Acupuncture Studies?
In yet another round of science by press release, a particularly unimpressive acupuncture study is making the rounds of the major news outlets proclaiming that acupuncture works. I guess that is a sort-of answer to my title question – why are so many scientifically worthless acupuncture studies being done? Let’s take a look at this particular study to see why it is...
Bisphenol A in Plastics – Should We Worry?
Is Bisphenol A a health hazard? We can't say for certain, but more research will help us know either way.
National Health Interview Survey 2007 – CAM Use by Adults
The Center for Disease Control (CDC) conducts an ongoing telephone survey of medical problems and health care utilization – called the National Health Interview Survey (NHIS). They recently released their data from 2007. This is the first year for which they specifically broke out questions assessing the use of so-called complementary and alternative medicine (CAM). CAM is a political/ideological entity, not a...
The Importance and Limitations of Peer-Review
Peer-review is a critical part of the functioning of the scientific community, of quality control, and the self corrective nature of science. But it is no panacea. It is helpful to understand what it is, and what it isn’t, its uses and abuses. Overview When the statement is made that research is “peer-reviewed” this is usually meant to refer to the fact...
Attitudes and Public Health
Increasingly there is a cultural trend toward health care freedom and empowerment. This trend is partly a reaction to the paternalism of the past, and reflects an overall change in attitude by the public toward all institutions and authority. Within medicine there has also been a move toward the partnership model of practice – where patients are well-informed full partners in the...
