There are many medical pseudosciences that persist despite a utter lack of either plausibility or evidence for efficacy. Some practices emerged out of their culture of origin, or out of the prevailing ideas of a pre-scientific age, while others were manufactured out of the imagination of perhaps well-meaning but highly misguided individual practitioners. They were just made up – homeopathy, for example, or subluxation theory.
Iridology belongs to this latter category – a system of diagnosis that was invented entirely by Ignatz Peczely, a Hungarian physician who first published his ideas in 1893. The story goes that Peczely as a boy found an owl with a broken leg. At the time he noticed a prominent black stripe in the iris of one eye of the owl. He nursed the bird back to health and then noticed that the black line was gone, replaced by ragged white lines. From this single observation Peczely developed the notion of iridology.
Peczely’s idea was that the iris maps to the rest of the body in some way, and therefore the flecks of color in the iris reflect the state of health of the various body parts. This basic approach to diagnosis or treatment is called the homonculus approach – the idea that one part of the body maps to the rest of the body, including the organ systems. Reflexology, auricular acupuncture, and even straight chiropractic follow this approach.
This is what might have happened next: Read more »

There has been much abuzz about “pox parties” – the practice of parents getting a bunch of unvaccinated kids together with an infected one (pick one, really, though chicken pox is the focus of the recent article in Time) in the hope that their little sweethearts become ill and therefore “naturally” immune to the disease. This deliberate infection involves things as seemingly innocent as breathing the same air as the infected to the stomach-turning sharing of bodily fluids (Saliva lemonade, anyone?). To compound the issue, it seems that parents aren’t always taking into account how the viruses are transmitted, and end up trying oral transmission to transmit a disease that is transmitted through the air. And yes, the whole thing is as stupid as it seems.
Given that the people partaking in these events have likely not vaccinated their children against anything else, these parties could be a source point for multiple highly contagious infections. Most of us have had chicken pox as children and don’t remember it fondly – now imagine having chicken pox with mumps, mono, and maybe a little hepatitis A to top it off. It is also easy to forget in Western luxury that these innocuous childhood illnesses are actually lethal. Just measles? Well, one death per 3000 measles infections might not seem like much, until you consider the fact that in 2008, 164,000 people died of the measles worldwide - approximately the same number of civilians that have died in the entire length of the current Iraq war. That’s an annual number, and it’s gone down by almost 80% over 10 years. How? Read more »

Sheril Kirshenbaum, research associate at the University of Texas Austin’s Center for International Energy & Environmental Policy, blogged this week under the headline, “Battle Hymn of the Science Journalist.” Excerpt:
There are many excellent science journalists who inhabit the blogosphere and those mainstream news outlets that still feature science sections. These talented individuals want to share your story, your research, and they appreciate and value what you do.
However, there are also a lot of horrible journalists making the rest of us look bad.. Writers who care less about getting it right, and more about trumping up controversy. Journalists whose headlines are notoriously misleading or false. Some Read more »

Hey there skeptifans. Here are the media Fails and Wins you sent me last week.
Edzard Ernst on alternative medicine
After Steve Jobs death, which we now know may have been hurried due to his decision to choose alternative treatments over evidence based ones, Maclean’s chose to run this Q&A with alternative medicine expert Edzard Ernst. Several years ago Dr. Ernst set out to find out if there is evidence to support the most popular alternative treatments. His findings were that the vast majority of alternative medicine is quackery. I hope this interview will help sway some people on the fence about chiropractic and other placebo treatments.

While we frequently on SBM target the worst abuses of science in medicine, it’s important to recognize that doing rigorous science is complex and mainstream scientists often fall short of the ideal. In fact, one of the advantages of exploring pseudoscience in medicine is developing a sensitive detector for errors in logic, method, and analysis. Many of the errors we point out in so-called “alternative” medicine also crop up elsewhere in medicine – although usually to a much less degree.
It is not uncommon, for example, for a paper to fail to adjust for multiple analysis – if you compare many variables you have to take that into consideration when doing the statistical analysis, otherwise the probability of a chance correlation will be increased.
I discussed just last week on NeuroLogica the misapplication of meta-analysis – in this case to the question of whether or not CCSVI correlates with multiple sclerosis. I find this very common in the literature, essentially a failure to Read more »
