Eric Pearl “Reconnects” with Hands-Off Healing
I first became aware of chiropractor Eric Pearl through the reprehensible movie The Living Matrix. Several months ago I reviewed that movie and described its segment featuring Pearl as follows: A 5 year old with cerebral palsy was allegedly healed by “reconnective healing” by a chiropractor who is shown waving his hands a few inches away from the child’s body. Problem: There...
The mammography wars heat up again
PRELUDE: THE PROBLEM WITH SCREENING If there’s one aspect of science-based medicine (SBM) that makes it hard, particularly for practitioners, it’s SBM’s continual requirement that we adjust what we do based on new information from science and clinical trials. It’s not easy for patients, either. To lay people, SBM’s greatest strength, its continual improvement and evolution as new evidence becomes available, can...
Short Attention Span SBM
The bar on this blog is set high. The entries are often complete, with no turn left unstoned. Yet, not every topic needs the full monty with every post. The blog has extensive evaluations on many topics, and new medical literature doesn’t require another complete analysis. Many new articles add incrementally to the literature and their conclusions need to be inserted into...
Christiane Northrup: more bad medicine
A question popped up on facebook the other day about Dr. Christiane Northrup, an OB/GYN who has been a frequent guest on Oprah. I hadn’t heard much about her for a while, but a foul taste still lingered from previous encounters with her work. So I went over to her website to see what fare she’s currently dishing up. It isn’t pretty....
CFLs, Dirty Electricity and Bad Science
Governments and environmental advocates are promoting compact fluorescent lightbulbs (CFLs) as a way of reducing electricity use, saving money, and reducing our carbon footprint. CFLs are not a perfect technology – when turned on they take a moment to fully brighten and they contain a small amount of mercury which requires special procedures for disposal. CFLs are likely also to be a...
How not to consult your biostatistician before doing an experiment
A friend of mine at work sent this video to me in great amusement. I just hope he wasn’t making a comment on my behavior when it comes to dealing with our biostatisticians. I have, of course, seen investigators approach biostatistians this late in the game. Not that I’ve ever flirted with this sort of behavior, of course. At least the researcher...
PTSD Breakthrough?: It’s Not Science Just Because Someone Says So
It infuriates me when someone misappropriates the word “science” to promote treatments that are not actually based on science. I have just read a book entitled The PTSD Breakthrough: The Revolutionary Science-Based Compass Reset Program by Dr. Frank Lawlis, a psychologist who is the chief content advisor for Dr Phil and The Doctors. There is very little science in the book and...
Clinical equipoise versus scientific rigor in cancer clinical trials
A critical aspect of both evidence-based medicine (EBM) and science-based medicine (SBM) is the randomized clinical trial. Ideally, particularly for conditions with a large subjective component in symptomatology, the trial should be randomized, double-blind, and placebo-controlled. As Kimball Atwood pointed out just last week, in EBM, scientific prior probability tends to be discounted while in SBM it is not, particularly for therapies...
Evidence-Based Medicine, Human Studies Ethics, and the ‘Gonzalez Regimen’: a Disappointing Editorial in the Journal of Clinical Oncology Part 2
NB: If you haven’t yet read Part 1 of this blog, please do so now; Part 2 will not summarize it. … At the end of Part 1, I wrote: We do not need formal statistics or a new, randomized trial with a larger sample size to justify dismissing the Gonzalez regimen. In his editorial for the JCO, Mark Levine made a...
Using attacks on science by the anti-vaccine movement as a “teachable moment”
A new study on the connection between vaccines and autism demonstrates two things: there is no connection, and those who think there is are not interested in science unless it supports what they already believe.
