Mea culpa to the max. I completely forgot that today is my day to post on SBM, so I’m going to have to cheat a little. Here is a link to a recent article by yours truly that appeared on Virtual Mentor, an online ethics journal published by the AMA with major input from medical students. Note that I didn’t write the initial scenario; that was provided to me for my comments. The contents for the entire issue, titled “Complementary and Alternative Therapies—Medicine’s Response,” are here. Check out some of the other contributors (I was unaware of who they would be when I agreed to write my piece).

Acupuncture has been in the news recently. A former President of South Korea had to undergo major surgery to remove an acupuncture needle that had somehow lodged in his lung. A recent study in Pain compiled a list of 95 published reports of serious complications of acupuncture including 5 deaths. Meanwhile, acupuncturists continue to insist that their procedures are “safe.”
Edzard Ernst et al.’s article “Acupuncture: Does it alleviate pain and are there serious risks? A review of reviews“ was published in the journal Pain in April 2011. It had two parts: (1) it was a systematic review of 57 systematic reviews showing that there was “little truly convincing evidence that acupuncture is effective in reducing pain,” and (2) it tabulated published reports of 5 deaths and 90 other serious complications of acupuncture treatments. I wrote an accompanying commentary, “Acupuncture’s claims punctured: Not proven effective for pain, not harmless.”
William Morris chastised me for not declaring a conflict of interest (!?) in my commentary. Now, in Acupuncture Today, he has criticized the Ernst et al. study itself.
Some of my fellow Science-Based Medicine (SBM) bloggers and I have been wondering lately what’s up with The Atlantic. It used to be one of my favorite magazines, so much so that I subscribed to it for roughly 25 years (and before that I used to read my mother’s copy). In general I enjoyed its mix of politics, culture, science, and other topics. Unfortunately, my opinion changed back in the fall of 2009, when, on the rising crest of the H1N1 pandemic, The Atlantic published what can only be described as an terrible bit of journalism lionizing the “brave maverick doctor” Tom Jefferson of the Cochrane Collaboration. The article, written by Shannon Brownlee and Jeanne Lenzer, argued, in essence, that vaccinating against H1N1 at the time was a horrendous waste of time and effort because the vaccine didn’t work. So bad was the cherry picking of data and framing of the issue as a narrative that consisted primarily of the classic lazy journalistic device of a “lone maverick” against the entire medical establishment that it earned the lovely sarcasm of our very own Mark Crislip, who wrote a complete annotated rebuttal, while I referred to the methodology presented in the article as “methodolatry.” Even public health epidemiologist Revere (who is, alas, no longer blogging but in his day provided a very balanced, science-based perspective on vaccination for influenza, complete with its shortcomings) was most definitely not pleased.
I let my subscription to The Atlantic lapse and have not to this day renewed it.
Be that as it may, last year The Atlantic published an article that wasn’t nearly as bad as the H1N1 piece but was nonetheless pretty darned annoying to us at SBM. Entitled Lies, Damned Lies, and Medical Science, by David Freedman, it was an article lionizing John Ioannidis (whom I, too, greatly admire) while largely missing the point of his work, turning it into an argument for why we shouldn’t believe most medical science. Now, Freedman’s back again, this time with a much, much, much worse story in The Atlantic in the July/August 2011 issue under the heading “Ideas” and entitled The Triumph of New Age Medicine, complete with a picture of a doctor in a lab coat in the lotus position. It appears to be the logical follow up to Freedman’s article about Ioannidis in that Freedman apparently seems to think that, if we can’t trust medical science, then there’s no reason why we shouldn’t embrace medical pseudoscience.
Basically, the whole idea behind the article appears to be that, even if most of alternative medicine is quackery (which it is, by the way, as we’ve documented ad nauseam on this very blog), it’s making patients better because of placebo effects and because its practitioners take the time to talk to patients and doctors do not. In other words, Freedman’s thesis appears to be a massive “What’s the harm?” argument coupled with a false dichotomy; that is, if real doctors don’t have the time to listen to patients and provide the human touch, then let’s let the quacks do it. Tacked on to that bad idea is a massive argumentum ad populum portraying alternative medicine as the wave of the future, in contrast to what Freedman calls the “failure” of conventional medicine.
Let’s dig in, shall we? I’ll start with the article itself, after which I’ll examine a few of the responses. I’ll also note that our very own Steve Novella, who was interviewed for Freedman’s article, has written a response to Freedman’s article that is very much worth reading as well.
Luis Fernando Verissimo, a Brazilian writer, once proposed “voodoopuncture”. Instead of going to the acupuncturist, you would be treated without leaving home. The voodoopuncturist would stick acupuncture needles in the voodoo dolls of you! I add that voodoopuncture could be outsourced to Haiti and/or China. It is a win-win-win situation!
— Leonardo Monasteri, Brazilian economist
As unbelievable as this might sound, “voodoopuncture” is no fiction at all.
The practice is called “Tong Ren healing,” and involves needling or hammering an acupuncture mannequin, as if it were a voodoo doll. The main Tong Ren “Master” in the US is an acupuncturist in the Boston area by the name of Tom Tam. He treats groups of terminally ill and debilitated patients in a deliverance ceremony that is noting but a revamped Taoist exorcism — only the clay or straw doll is replaced by a plastic mannequin:
Unfortunately, Tom Tam is not the only licensed healthcare provider who is treating patients with hocus pocus and crackpottery. There are over 30,000 other adepts of Traditional Chinese Medicine (TCM) in the US who practice medicine based on notions of health and disease that are rooted in paranormal and magical beliefs. Some of these practitioners take their delusions to the outer limits of absurdity: consider, for instance, “acutonics” and “colorpuncture” as described in these videos:
In anthropology of religion, the principles that underline the above practices are called “imitation” (e.g. using a doll to affect a person), and “correspondence” (e.g. using a sound to affect an object). They are the hallmarks of what is called “sympathetic magic,” meaning the belief that a person, or a thing, can be affected through something that represents it, or that has similar attributes.1 The principle of magical correspondence in TCM is called wu xing (五行) in Chinese, and is known as the Five Phases/Elements Theory in English. It can be summarized as follows:
Explanatory studies are done under controlled conditions to determine whether a treatment has any efficacy compared to a placebo. Pragmatic studies are designed to assess how the intervention performs in everyday real world practice. Pragmatic studies measure practical success but don’t determine actual efficacy: that requires a proper randomized controlled trial (RCT) with an appropriate control. Pragmatic studies have their place, but they can sometimes make an ineffective treatment look good: a phenomenon I have christened Cinderella Medicine.
When an article is published in a medical journal, the authors must disclose any conflicts of interest. This is important, because even if they think owning stock in the drug company won’t influence their scientific judgment, we know that subtle biases can creep in to somehow affect the findings of studies. It has been shown that studies funded by drug companies are more likely to get positive results for their drug than studies funded by independent sources. Andrew Wakefield, author of the infamous retracted Lancet study suggesting a relationship between MMR vaccine and autism, was severely chastised for not disclosing that he received money from autism litigators and expected to earn a fortune from his own patented products if the MMR vaccine could be discredited.
I was recently contacted by an acupuncturist who plans to critique an article I wrote. It was a commentary in the journal Pain that accompanied a systematic review of systematic reviews of acupuncture by Ernst et al. For details of Ernst’s and my articles, see my previous post. He challenged my statement that I had no conflicts of interest to report. He apparently thinks I should have said I have a conflict of interest in that I am anti-CAM and anti-acupuncture. When he writes about my article, he plans to attack me for not declaring this alleged conflict of interest and he plans to set a good example with a conflict of interest statement of his own, divulging that he makes his living practicing acupuncture, has financial investments in it and many personal relationships, that his self-identity and prestige are dependent on his belief in acupuncture’s efficacy, and that he is biased towards constructivism and away from positivism. (I think this is a fancy way of saying he favors experience over the scientific method.) I agree that he has conflicts of interest, but was I wrong to say I had no conflicts of interest? I don’t think so. (more…)
Not only his name and his titles of nobility were forged, but parts of the teachings of the man who introduced acupuncture to Europe were also invented. Even today, treatments are provided based on his fantasies.

Decades before President Nixon’s visit to communist China, and before the articles in the Western popular press on the use of acupuncture in surgery, a Frenchman by the name of George Soulié de Morant (1878-1955), published a series of colorful accounts of the use of acupuncture in early 20th-century China. His work led to the creation of a school of thought known as “French energetics,” which has become the theoretical foundation for many proponents of acupuncture in the West, including Joseph Helms, MD, the founder and former director of the American Academy of Medical Acupuncture (AAMA), and the founder of the acupuncture certification course for physicians.
But just as the medical community gradually learned that the reports of the use of acupuncture in surgery in communist China were inaccurate, exaggerated, or even fraudulent, we are now learning that the reports on the use and efficacy of acupuncture by Soulié de Morant were also fabricated.
According to a 2010 article published in Germany by Hanjo Lehmann in the Deutsches Ärzteblatt (a short version was published in Süddeutsche Zeitung), there is no real evidence that the Frenchman who is considered the father of Western acupuncture ever stuck a needle in anyone in China, and he probably never witnessed a needling.
Steven Salzberg, a friend of this blog and Director of the Center for Bioinformatics and Computational Biology at the University of Maryland, is on the editorial boards of three of the many journals published by BioMed Central (BMC), an important source of open-access, peer-reviewed biomedical reports. He is disturbed by the presence of two other journals under the BMC umbrella: Chinese Medicine and BMC Complementary and Alternative Medicine. A couple of days ago, on his Forbes science blog, Dr. Salzberg explained why. Here are some excerpts:
The Chinese Medicine journal promotes, according to its own mission statement, studies of “acupuncture, Tui-na, Qi-qong, Tai Chi Quan, energy research,” and other nonsense. Tui na, for example, supposedly “affects the flow of energy by holding and pressing the body at acupressure points.”
Right. What is this doing in a scientific journal?… I support BMC…But their corporate leaders seem to care more about expanding their stable than about maintaining the integrity of science. Chinese Medicine simply does not belong in the company of respectable scientific journals.
Forming a scientific journal whose goal is to validate antiquated, unproven superstitions is simply not science, whatever the editors of Chinese Medicine claim.
BMC should be embarrassed to be publishing journals that promote anti-scientific theories and otherwise muddy the literature. By supporting these journals, they undermine the credibility of many excellent BMC journals. They should cut these journals loose.
The scientific approach to understanding the world includes the process of carefully separating out variables and effects. Experiments, in fact, are designed specifically to control for variables. This can be especially challenging in medicine, since the body is a complex and variable system and there are always numerous factors at play. We often characterize the many variables that can influence the outcome in a clinical study as “placebo effects” or “non-specific effect” – things other than a specific response to the treatment in question.
A common error to make when interpreting clinical studies is to confuse non-specific effects – those that result from the therapeutic interaction or the process of observation – with a specific effect from the treatment being studied. While this is broadly understood within the scientific medical community, it seems that within certain fields proponents are going out of their way to sell non-specific effects as if they were specific effects of the favored treatment.
This is perhaps most true for acupuncture. As has been discussed numerous times on SBM, the consensus of the best clinical studies on acupuncture show that there is no specific effect of sticking needles into acupuncture points. Choosing random points works just as well, as does poking the skin with toothpicks rather than penetrating the skin with a needle to elicit the alleged “de qi”.
Believers in acupuncture claim it is supported by plenty of published scientific evidence. Critics disagree. Thousands of acupuncture studies have been done over the last several decades, with conflicting results. Even systematic reviews have disagreed with each other. The time had come to re-visit the entire body of acupuncture research and try to make sense out of it all. The indefatigable CAM researcher Edzard Ernst stepped up to the plate. He and his colleagues in Korea and Exeter did an exhaustive study that was published in the April 2011 issue of the medical journal Pain: “Acupuncture: Does it alleviate pain and are there serious risks? A review of reviews.” It is accompanied by an editorial commentary written by yours truly: “Acupuncture’s claims punctured: Not proven effective for pain, not harmless.” (The editorial is reproduced in full below.)
Ernst et al. systematically reviewed all the systematic reviews of acupuncture published in the last 10 years: 57 systematic reviews met the criteria they set for inclusion in their analysis. They found a mix of negative, positive, and inconclusive results. There were only four conditions for which more than one systematic review reached the same conclusions, and only one of the four was positive (neck pain). They explain how inconsistencies, biases, conflicting conclusions, and recent high quality studies throw doubt on even the most positive reviews.
They also demolished the “acupuncture is harmless” myth by reporting 95 published cases of serious adverse effects including infection, pneumothorax, and 5 deaths. Some but not all of these might have been avoided by better training in anatomy and infection control. (more…)
