Eating Placentas: Cannibalism, Recycling, or Health Food?

After giving birth, most mammals eat the afterbirth, the placenta. Most humans don’t. Several hypotheses have been suggested as to why placentophagy might have had evolutionary survival value, but are there any actual benefits for modern women? Placentophagy has been recommended for various reasons, from nutritional benefit to preventing postpartum depression to “honoring the placenta.” In other cultures, various rituals surround the...

Ethics in human experimentation in science-based medicine

Science-based medicine depends upon human experimentation. Scientists can do the most fantastic translational research in the world, starting with elegant hypotheses, tested through in vitro and biochemical experiments, after which they are tested in animals. They can understand disease mechanisms to the individual amino acid level in a protein or nucleotide in a DNA molecule. However, without human testing, they will never...

Of SBM and EBM Redux. Part IV, Continued: More Cochrane and a little Bayes

OK, I admit that I pulled a fast one. I never finished the last post as promised, so here it is. Cochrane Continued In the last post I alluded to the 2006 Cochrane Laetrile review, the conclusion of which was: This systematic review has clearly identified the need for randomised or controlled clinical trials assessing the effectiveness of Laetrile or amygdalin for...

Topical NSAIDs

I have a mental basket of drugs that I suspect may be placebos. In that basket were the topical versions of non-steroidal anti-inflammatory drugs (NSAIDs). When the first products were commercially marketed over a decade ago, I found the clinical evidence unconvincing, and I suspected that the modestly positive effects were probably due to simply rubbing the affected area, or possibly due...

Yes, it's true that placebos are just as powerful as homeopathy. Unfortunately, that doesn't mean what believers in integrative medicine think it does.

Placebo Effect for Pain

It has long been recognized that there are substantial multifactorial placebo effects that create real and illusory improvements in response to even an inactive treatment. There is a tendency, however (especially in popular discussion), to oversimplify placebo effects – to treat them as one mind-over-matter effect for all outcomes. Meanwhile researchers are elucidating the many mechanisms that go into measured placebo effects,...

Questioning the Annual Pelvic Exam

A new article in the Journal of Women’s Health by Westhoff, Jones, and Guiahi asks “Do New Guidelines and Technology Make the Routine Pelvic Examination Obsolete?” The pelvic exam consists of two main components: the insertion of a speculum to visualize the cervix and the bimanual exam where the practitioner inserts two fingers into the vagina and puts the other hand on...

Now here’s something that can be used to counter the antivaccine musical stylings of Mike Adams and his song Don’t Inject Me: Play ZDoggMD’s Immunize!: Sometimes, even on SBM, we need to lighten things up a bit. Take that, Mike Adams!

Skepticism versus nihilism about cancer and science-based medicine

Last Friday, Mark Crislip posted an excellent deconstruction of a very disappointing article that appeared in the most recent issue of Skeptical Inquirer, the flagship publication of the Committee for Skeptical Inquiry (CSI). I say “disappointing,” because I was disappointed to see SI (Skeptical Inquirer, not Sports Illustrated) publish such a biased, poorly thought out article, apparently for the sake of controversy....

An ICD Code for the Running Piglets!

Deadly Indeed

There are sources of information I inclined to accept with minimal questioning.  I do not have time to examine everything in excruciating detail, and like most people, use intellectual short cuts to get through the day.  If it comes from Clinical Infectious Diseases or the NEJM, I am inclined to accept the conclusions without a great deal of analysis, especially for non-infectious...
