NEJM and Acupuncture: Even the best can publish nonsense.

I realize that the New England Journal of Medicine (NEJM) review of acupuncture has already been covered by Drs. Gorski and Novella. But my ego knows no bounds; so I thought I would add my two cents, especially since this review, more than any paper I have read, generates a deep sense on betrayal.

There was a time when I believed my betters. Then the Annals of Internal Medicine had their absolutely ghastly series on SCAMS, the publication of which was partly responsible for interest in the topic. Since that series of articles, I have doubt whenever I read an Annals article. When a previously respected journal panders completely to woo, they lose all respectability. Sure, the editors that were responsible for that travesty are long gone, but the taint remains. I tell my kids that once a trust has been violated, it is difficult to get it back. The Annals has permanently lost my trust, I am afraid.

But we will always have Paris. I mean the NEJM. The NEJM is the premier medical journal. Just because an article is published in the NEJM doesn’t mean it’s right; the results of clinical trials are always being superseded by new information. But the article has supposedly been rigorously peer reviewed. Its like Harvard and… Oops, Bad example. Harvard, as we have seen, has feet of clay, and so, evidently, does the The New England Journal of Medicine.

Goodness, gracious, great balls of fire, the editors of the NEJM have fallen into the depths of nonsense with this one.

Homeoprophylaxis: An idea whose time has come—and gone

One of the strengths of modern medical education is its emphasis on basic science.  Conversely, the basic weakness of so-called alternative medicine is its profound ignorance of science and its reliance on magical thinking.  Nowhere is this more apparent than in the attempts of altmed cults to conduct and publish research.  From “quantum water memory” to “almost as good as placebo”, the altmed literature is filled with basic failures in the proper formulation and testing of hypotheses.

One of the finest examples of these failures was just published in the journal Homeopathy.  Leaving aside for the moment the absurdity of a journal devoted to magic, let’s see what they did here. (more…)

Venous Insufficiency in Multiple Sclerosis

There is an interesting controversy raging in the Multiple Sclerosis (MS) world that reflects many of the issues we discuss at science-based medicine. Dr. Paolo Zamboni, and Italian vascular surgeon, has now published a series of studies claiming that patients with clinically defined MS have various patterns of chronic cerebrospinal venous insufficiency (CCSVI). Further Dr. Zamboni believes CCSVI is a major cause of MS, not just a clinical side-consequence, and is exploring treatment with venous angioplasty or stenting.

The claims have captured the attention of MS patients, many of whom have a progressive course that is only partially treated by currently available medications. There are centers popping up, many abroad (such as India), providing the “liberation procedure” and anecdotes of miraculous cures and spreading over the internet. There is even a Facebook page dedicated to CCSVI, and you can read the anecdotes for yourself. Many profess dramatic improvement immediately following the procedure, which seems unlikely even if Zamboni’s hypothesis is correct.

Zamboni is also getting attention from neurologists and MS specialists, who remain skeptical because Zamboni’s claims run contrary to years of research and thousands of studies pointing to the current model of MS as an autoimmune disease.

Alchemy Is Back

Alchemy is alive and well! Yes, that medieval precursor of chemistry, that chimerical search for the philosopher’s stone and the transmutation of lead to gold. Modern alchemists have found the philosopher’s stone and are selling it and teaching people how to make it themselves out of dew and Celtic sea salt.

The philosopher’s stone apparently is an elixir of life that you have to take on a regular basis. According to Nicholas Collette, it “completely eliminates the pharmaceutical industries by curing EVERY disease, and opens the mind to it’s [sic] full potential.”   It extends the life span, reverses the aging process, and opens the door to psychic power.

Instructions for making it are detailed on this website. It takes time and is complicated, but the starting ingredient is simple: morning dew.  (more…)

Germ theory denialism: A major strain in “alt-med” thought

The longer I’m in this whole science-based medicine thing, not to mention the whole skepticism thing, the more I realize that no form of science is immune to woo. To move away from medicine just for a moment, even though I lament just how many people do not accept evolution, for example, I can somewhat understand it. Although the basics of the science and evidence support the theory of evolution as the central organizing principle of all biology, much of the evidence is not readily apparent to those who don’t make it a calling to study biology, evolution, and speciation. It’s not like, for example, gravity, which everyone experiences and of which everyone has a “gut level” understanding. So, not unexpectedly, when the theory of evolution conflicts with a person’s religious beliefs, for most people it’s very easy to discount the massive quantities of evidence that undergird the theory of evolution. It’s not so easy to discount the evidence for gravity.

In many ways, medicine is similar to evolution, but the situation is possibly even worse. The reason is that much of the evidence in medicine is conflicting and not readily apparent to the average person. There’s more than that, though, in that there are a number of confounding factors that make it very easy to come to the wrong conclusion in medicine, particularly when looking at single cases. Placebo effects and regression to the mean, for example, can make it appear to individual patients that, for example, water (i.e., what the quackery that is homeopathy is) or placebo interventions (i.e., acupuncture) cures or improves various medical conditions. Add to that confirmation bias, the normal human cognitive quirk whereby all of us — and I do mean all of us — tend to remember information that reinforces our preexisting beliefs and to forget information that would tend to refute those beliefs — and, at the level of a single person or even practitioner, it’s very, very easy to be misled in medicine into thinking that quackery works. On the other hand, at the single patient/practitioner level, one can also see evidence of the efficacy of modern medicine; for example, when a person catches pneumonia, is treated with antibiotics, and recovers quickly. Regardless of whether they’re being used to demonstrate quackery or scientific medicine, because personal experience and the evidence that people observe at the level of the people they know can be very deceptive in medicine, science-based medicine, with its basic science underpinnings and clinical trial evidence, is necessary to try to tease out what actually works and what doesn’t.

Medicine does, however, have its version of a theory of evolution, at least in terms of how well-supported and integrated into the very fabric of medicine it is. That theory is the germ theory of disease, which, just as evolution is the organizing principle of biology, functions as the organizing principle of infectious disease in medicine. When I first became interested in skepticism and medical pseudoscience and quackery, I couldn’t envision how anyone could deny the germ theory of disease. It just didn’t compute to me, given how copious the evidence in favor of this particular theory is. It turns out that I was wrong about that, too.

On Friday there was a video released that provides a very clear, succinct explanation of germ theory denialism:

Can it get any worse?: industrial bleach as cancer and HIV cure

On the heels of Scott Gavura’s superb post yesterday on dietary supplement regulation in the US and Canada, I bring you one of the most egregious and obscene product cases I have seen in 15 years of teaching on botanical and non-botanical products: Miracle Mineral Solution. Please accept my apologies in advance for not having a scholarly post for you today – this is just too unbelievable not to share with Science-Based Medicine readers.

On July 30, the FDA released this warning:


FDA NEWS RELEASE

For Immediate Release: July 30, 2010
Media Inquiries: Elaine Gansz Bobo, 301-796-7567, elaine.bobo@fda.hhs.gov
Consumer Inquiries: 888-INFO-FDA

FDA Warns Consumers of Serious Harm from Drinking Miracle Mineral Solution (MMS)
Product contains industrial strength bleach

The U.S. Food and Drug Administration is warning consumers not to take Miracle Mineral Solution, an oral liquid also known as “Miracle Mineral Supplement” or “MMS.”  The product, when used as directed, produces an industrial bleach that can cause serious harm to health.

The FDA has received several reports of health injuries from consumers using this product, including severe nausea, vomiting, and life-threatening low blood pressure from dehydration.

Consumers who have MMS should stop using it immediately and throw it away.

MMS is distributed on Internet sites and online auctions by multiple independent distributors. Although the products share the MMS name, the look of the labeling may vary.

The product instructs consumers to mix the 28 percent sodium chlorite solution with an acid such as citrus juice. This mixture produces chlorine dioxide, a potent bleach used for stripping textiles and industrial water treatment. High oral doses of this bleach, such as those recommended in the labeling, can cause nausea, vomiting, diarrhea, and symptoms of severe dehydration.

MMS claims to treat multiple unrelated diseases, including HIV, hepatitis, the H1N1 flu virus, common colds, acne, cancer, and other conditions. The FDA is not aware of any research that MMS is effective in treating any of these conditions. MMS also poses a significant health risk to consumers who may choose to use this product for self-treatment instead of seeking FDA-approved treatments for these conditions.

The FDA continues to investigate and may pursue civil or criminal enforcement actions as appropriate to protect the public from this potentially dangerous product.

The FDA advises consumers who have experienced any negative side effects from MMS to consult a health care professional as soon as possible and to discard the product. Consumers and health care professionals should report adverse events to the FDA’s MedWatch program at 800-FDA-1088 or online at www.fda.gov/medwatch/report.htm.

Supplement Regulation: Be Careful What You Wish For

A recurring theme at SBM is the regulation of supplements, and the impact and consequences of the Dietary Supplement Health and Education Act of 1994 (DSHEA). As one of SBM’s international contributors, I thought it might be helpful to look at how the DSHEA stacks up against the equivalent regulations of its neighbor to the north, Canada. Given the multiple calls for overhauls and changes to DSHEA, an international comparison may help focus the discussion around what a more science-based framework could look like.

Briefly, the DSHEA is an amendment to the U.S. Federal Food, Drug and Cosmetic Act that establishes a regulatory framework for dietary supplements. It effectively excludes manufacturers of these products from virtually all regulations that are in place for prescription and over-the-counter drugs. The FDA notes:

Generally, manufacturers do not need to register their products with FDA nor get FDA approval before producing or selling dietary supplements. Manufacturers must make sure that product label information is truthful and not misleading. FDA’s post-marketing responsibilities include monitoring safety, e.g. voluntary dietary supplement adverse event reporting, and product information, such as labeling, claims, package inserts, and accompanying literature. The Federal Trade Commission regulates dietary supplement advertising.

Acupuncture Pseudoscience in the New England Journal of Medicine

Here is the conclusion quoted from a recent New England Journal of Medicine (NEJM) review article on acupuncture for back pain:

As noted above, the most recent wellpowered clinical trials of acupuncture for chronic low back pain showed that sham acupuncture was as effective as real acupuncture. The simplest explanation of such findings is that the specific therapeutic effects of acupuncture, if present, are small, whereas its clinically relevant benefits are mostly attributable to contextual and psychosocial factors, such as patients’ beliefs and expectations, attention from the acupuncturist, and highly focused, spatially directed attention on the part of the patient.

Translation – acupuncture does not work. Why, then, are the same authors in the same paper recommending that acupuncture be used for chronic low back pain? This is the insanity of the bizarro world of CAM (complementary and alternative medicine). Yesterday David covered the same article, which I had also covered on NeuroLogica, but we both thought this issue important enough to document our thoughts and objections on SBM.

Credulity about acupuncture infiltrates the New England Journal of Medicine

One of the things that disturbs me the most about where medicine is going is the infiltration of quackery into academic medicine. So prevalent is this unfortunate phenomenon that Doctor RW even coined a truly apt term for it: Quackademic medicine. In essence, pseudoscientific and even prescientific ideas are rapidly being “integrated” with science-based medicine, or, as I tend to view it, quackery is being “integrated” with scientific medicine, to the gradual erosion of scientific standards in medicine. No quackery is too quacky, it seems. Even homeopathy and naturopathy can seemingly find their way into academic medical centers.

Probably the most common form of pseudoscience to wend its way into what should be bastions of scientific medicine is acupuncture. Harvard, Stanford, Yale, M. D. Anderson, and many others, they’ve all fallen under the sway of the idea that somehow sticking thin little needles into points that bear no relationship to any known anatomic structure and that supposedly “unblock” the flow of some sort of “life energy” that can’t be detected by any means that science has. Most recently, as I described, studies that seek to “prove that acupuncture works” have found their way into high quality, high impact journals whose editors should know better but apparently can’t recognize that the evidence in the study doesn’t actually show what the authors claim it shows. Even so, there are some journals that I didn’t expect to see this sort of infiltration of quackademic medicine. Granted, I never expected it to show itself in one of the Nature journals, as it did in the study I just mentioned. I also never expected it to show up in that flagship of clinical journals, a journal that is one of the highest impact and most read medical journals that exists. I’m talking the New England Journal of Medicine, and, unfortunately, I’m also talking an unfortunately credulous article from Dr. Brian M. Berman, who is the founder of the Center for Integrative Medicine, University of Maryland School of Medicine and the holder of multiple NCCAM center grants, and other institutions, entitled Acupuncture for Chronic Low Back Pain.

Home Birth Safety

More and more American women (1 in 200) are opting for home birth, and midwife-assisted home birth is common in other developed countries. How safe is it compared to birth in a hospital? A new study sheds some light on the subject. It was recently published in the American Journal of Obstetrics and Gynecology: Maternal and newborn outcomes in planned home birth vs planned hospital births: a metaanalysis, by Wax et al.

All the existing studies have flaws. It would be ideal to do a study where women were randomly assigned to home or hospital birth; that isn’t possible, so we have to fall back on studies that are possible. Just comparing home births to hospital births isn’t good enough, because high-risk births occur primarily in hospitals, and between 9% and 37% of planned home births end up with transfer to the hospital during labor and are converted into hospital births. Cohort studies comparing planned home with planned hospital births provide the best sources of data by intended delivery location. There have been several such studies, but the numbers were small and the results were inconclusive. This new study is a meta-analysis that combines the data into one large set for better understanding. (more…)
