Today’s post is a reluctant challenge. I’m nominating my own alma mater, the University of Toronto, as the new pseudoscience leader among large universities – not just in Canada, but all of North America. If you can identify a large university promoting or embracing more scientifically questionable activities, I’ll happily buy you a coffee. Yes, it’s personal to me, as I have two degrees from U of T. But I’m more concerned about the precedent. If Canada’s largest university is making decisions that appear to lack a careful consideration of the scientific evidence, then what does that suggest about the scientific standards for universities in Canada?

As I have noted before, more is published on acupuncture and traditional Chinese pseudo-medicine than the other SCAM. Here are some of the articles that drew my attention.
Captain Hook and acupuncture
Here is one of the more curious articles on acupuncture I have yet to find, “Psychophysical and neurophysiological responses to acupuncture stimulation to incorporated rubber hand.”
I did not know this, but you can fool a person into thinking that a rubber hand is their own.
The synchronous tactile stimulation of the real hand of an individual and rubber hand leads to the feeling that the rubber hand is incorporated with the body of that individual. This is referred to as the rubber hand illusion (RHI), and it occurs because the brain is attempting to interpret the interaction of the visual, tactile, and proprioceptive systems of the body, which in turn, leads to a re-calibration of the touch and the felt position of the hand. The multimodal visuotactile stimulation inherent in the RHI induces the brain to temporarily incorporate external objects into its body image. In addition, when the experimenter threatens the rubber hand with a needle during this illusion, it generally elicits an enhanced sympathetic response and a measurable cortical anxiety response, which indicates that the bodily ownership of the rubber hand causes changes in the interoceptive system of the brain.
Cool. Check out this video to see how it is done. So what happens when you do acupuncture on a rubber hand that the brain thinks is its own?
The findings of the present study clearly demonstrate that acupuncture stimulation to a rubber hand resulted in the experience of the DeQi sensation when the rubber hand was fully incorporated into the body.
As judged by fMRI findings (always taken with a grain of salt substitute) and patient reports. DeQi is what dey feel when de needle is twirled in de skin. (more…)
Back in 2004, data from the 2002 National Health Interview Survey (NHIS) appeared in a report titled “Complementary and Alternative Medicine Use Among Adults: United States, 2002.” It showed a whopping 62% of adults had used CAM in the past 12 months, but only if prayer for health reasons was included. With prayer excluded, the percentage was substantially lower, at 35%.
“CAM” was defined as:
a group of diverse medical and health care systems, therapies, and products that are not presently considered to be part of conventional medicine.
The authors noted that, in earlier surveys of CAM use, “CAM has been operationally defined in a variety of ways” and the lists of CAM interventions/therapies included “varied considerably among the surveys.”
The most commonly used CAM therapies (excluding prayer) were non-vitamin, non-mineral natural products (18.9%), deep breathing exercises (11.6%), chiropractic care (7.5%), yoga (5.1%), massage (5.0%) and diet-based therapies (3.5%). CAM was most often used to treat back pain or problems, head or chest colds, neck pain or problems, joint pain or stiffness, and anxiety or depression. Most CAM use was self-prescribed. Rebranding things like exercise (yoga) as “CAM” was in the mix from the get-go.
The New Year starts with telomeres as the trendiest of trendy biomarkers. As seen in Time, telomeres are the means to monitor our well-being so we can protect ourselves from all sorts from threats, including early death.
A skeptic needs to do considerable homework in order to muster the evidence needed to counter the latest exaggerated, premature, and outright pseudoscientific claims about telomere length being a measure of “cellular aging” and therefore how long we’re going to live.
What is a telomere and why does its length matter?
Harriet Hall recently described telomeres:
Every chromosome has a telomere, a repeated sequence of nucleotides at the end of the DNA strand. It is a disposable section that carries no genetic information. For vertebrates, the nucleotide sequence is TTAGGG; this repeats from 300 to several thousand times according to the species of animal. Telomeres are sort of like the aglet, that little hard piece on the end of a shoelace that keeps it from unraveling. They protect the end of the chromosome and keep it from losing important genes or sticking to other chromosomes.

Talk of telomeres isn’t just being used to sell dubious diagnostic tests and dietary supplements. There is a strong push to make telomere length the currency of how we think, measure, and do science about our health and well-being, and how we target our health interventions. Strong efforts are made to attach the science of telomeres to urgings that we take up yoga, meditation, and “being there” to save our lives.
Several snarks were painfully maimed in the writing of this blog post
I read a lot of the pseudo-medical websites. The writing is at best pedestrian, often turgid, and, at its worst, incoherent. It is rarely either engaging or clever.
Wit, the clever bon mot, the amusing turn of phrase or retort, is rare at best. So rare I cannot think of an example. It is ironic that those who engage in fantastical treatments are so often lacking in cleverness with language and thought. The closest you get to humor are the painfully-lame cartoons at the Natural News. I am sure that the readers will flood the comments with examples of all the clever writing I have missed in the world of pseudo-medicine just to prove me wrong. Not that the reality-based world is much better. It is the rare author on the internet whose style keeps me coming back for more.
But for some reason I found “Dear Science Based Medicine, Just a Few Questions About Acupuncture” funny and engaging, at odds with most of the purple quasi-paranoid articles I normally read. Just the right amount of chatty snarkiness to be enjoyable, at least for me. So refreshing given the style of the usual pro-acupuncture comments. Your millage may vary. (more…)
I am happy to report some good news: chiropractors, naturopaths, acupuncturists and assorted other practitioners of pseudo-medicine didn’t fare too well in the 2013-2014 state legislative sessions.
We’ve been following their legislative efforts all year over at the Society for Science-Based Medicine. Some state legislatures meet in yearly sessions. At the end of the year, pending bills die with the session. Some meet only every other year. Others meet in two-year sessions and, in some of these, legislation introduced in one year carries over to the next year. All states with two-year sessions ended these sessions at the close of 2014, except New Jersey and Virginia. If you want to see how your state operates, several websites can help you: MultiState Associates, National Conference of State Legislatures and StateScape.
Chiropractors are already licensed in all 50 states and all of their practice acts permit the detection and correction of the non-existent subluxation. Having achieved that goal, the focus of chiropractic legislative efforts is to expand their scope of practice (the holy grail, for some, being primary care physician status), turf protection and mandates requiring insurance reimbursement or their inclusion in various activities, such as sports physicals, concussion treatment, and scoliosis detection programs.
The most interesting chiropractic bill, one from Oklahoma, didn’t fall into any of those categories:
Chiropractic physicians in this state shall obtain informed, written consent from a patient prior to performing any procedure that involves treatment of the patient’s cervical spine and such informed consent shall include the risks and possible side effects of such treatment including the risk of chiropractic stroke.

I’m cheating. No, I’m recycling. ‘Tis the season to have to no time to get anything done. Since I know none of you pay attention to the blog of at the Society for Science-Based Medicine and I have no time with work and the holidays to come up with new material, I am going to collect and expand on the entries on acupuncture I wrote from SfSBM. Anything I write really is worth reading twice. I really need to make my multiple personality disorder work for me, but the Goth cowgirl persona is a luddite at best, so you are stuck with the over -extended ID doctor. Here goes.
A recent study in the Journal of General Internal Medicine evaluated a treatment for constipation. It tested whether training patients to massage the perineum (the area between the vagina or scrotum and the anus) would improve their reported bowel function and quality of life at 4 weeks after training. They found that it did. It’s a simple, innocuous treatment that may be worth trying, but why, oh why, did they have to call it “acupressure”? That irritated me. Should it have? Why should it matter? Isn’t a rose by any other name still a rose? Is this a meaningless semantic quibble and hypersensitivity on my part, or am I right to see it as yet another example of quackademia’s attempts to infiltrate science-based medicine? I’ll explain my thinking and let you decide for yourself. (more…)
In the tradition of James Randi, a Chinese doctor who is an outspoken critic of Traditional Chinese Medicine (TCM) has issued a challenge to its proponents. He has put up 50,000 yuan (about $8,000), which has been matched by donors for a total of over 100,000 yuan, to any TCM practitioner who can use pulse diagnosis to determine with accuracy whether females subjects are pregnant.
Ah Bao is the blogging pseudonym of a burn-care doctor at Beijing Jishuitan hospital. He is trained in scientific medicine and has criticized his country for clinging to pre-scientific philosophy-based health care. He calls TCM “fake science” and now wants to demonstrate that the claims of TCM practitioners are without factual basis.
His challenge is a good one because it focuses on a clear criterion. Subjects will either be pregnant or not pregnant, and the TCM practitioner, using only pulse analysis and blinded to the patient themselves, must determine with an 80% accuracy which subjects are pregnant. A TCM practitioner, Zhen Yang, has taken him up on the challenge and they are now working out the details. (more…)
