The last two weeks have brought good news to those who seek to hold chiropractic to the standard of evidence and science-based medicine.
In the first bit of good news, on October 14th Simon Singh was granted permission to appeal the High Court ruling on meaning of the term “bogus” within his original article. I’m sure most readers of this blog are familiar with Simon Singh’s legal battle with the British Chiropractic Association (BCA) regarding an article in The Guardian entitled “Beware the Spinal Trap.” We’ve covered it several times over the last year and will continue to do so as the case progresses. The nuances of the British legal system (or any legal system for that matter) are beyond my ken, and are far better explained by Jack of Kent here. The take-home point is that gaining permission to appeal the ruling on meaning was virtually essential if Simon were to have any real chance of winning this lawsuit.
Even if the BCA should win its lawsuit for libel against Singh, it seems likely to be something of a pyrrhic victory. After all, in the year since this story began, we’ve been belatedly provided with the BCA’s best evidence in support of chiropractic’s efficacy, and promptly treated to its subsequent evisceration.

Charlene Werner is getting a lot of attention she probably did not anticipate or desire. She is the star of a YouTube video in which she explains the scientific basis of homeopathy. Before you watch it, make sure you are sitting down, relax, and brace yourself for an onslaught of profound scientific illiteracy combined with stunning arrogance. For those with more delicate constitutions I will give you the quick summary:
Einstein taught us that energy equals matter and light, but because matter can be condensed down to a very small space if you remove all the empty space between the elementary particles (I am paraphrasing to make her statements minimally coherent), we can mostly ignore matter. Therefore energy is light, and we are all made of energy – not matter (or at least so little matter, you can ignore it). Stephen Hawking then came up with string theory, which tells us that all matter (which we can ignore) is made of vibrating strings. Therefore we are made of vibrating energy. All diseases are therefore caused by unhealthy vibrational states, and all disease can be treated by returning the body to a previous healthy vibrational state. This can be done with homeopathy, which extracts the vibrational energy out of stuff and places it in a small pill that can be used at any time.
Got it? This is now my favorite example of meaningless pseudobabble from a CAM proponent. Also, I am not picking on some unrepresentative crank – this is as good as homeopathy gets. Werner may be more clumsy and fumbling than more eloquent homeopathy proponents, but when you strip it down, magical vibrations is what you get. But Werner does a fabulous job of exposing the gaping holes is homeopathic nonsense.
For those who battle tirelessly against the never ending onslaught of anti-vaccine propaganda, misinformation, and fear, there was great news the other day from Merck. The pharmaceutical company, and maker of the MMR vaccine against measles, mumps, and rubella, has decided not to resume production of the individual, or “split”, components of the vaccine. A Merck representative made the announcement during a meeting of the CDC Advisory Committee on Immunization Practices (ACIP) on Tuesday. During previous ACIP meetings, science experts on that committee presented compelling arguments against continued, large scale production of the monovalent components of the MMR vaccine, which were echoed by scientists in Merck’s vaccine division. In a moment, I’ll discuss the arguments against the split vaccine, and why this is so important a decision. First, some background on the issue of splitting the MMR.
I’d like to thank revere right now publicly. He’s taught me a new word:
Methodolatry: The profane worship of the randomized clinical trial as the only valid method of investigation.
Many of you have e-mailed me and other SBM bloggers about a recent article in The Atlantic by Shannon Brownlee and Jeanne Lenzer, two reporters whose particular bias is that we as a nation are “over treated.” That may be true, although not to the extent that Brownlee, at least, seems to think, and her article on swine flu was truly biased and painful to read. Moreover, “methodalatry” perfectly describes one of the complaints we at SBM have about the “evidence-based medicine” paradigm. So I’m really glad that revere took it on and demolished it.
The hero of The Atlantic article, Tom Jefferson clearly has an agenda about flu vaccines. Indeed, he has such an agenda that he was invited to the National Vaccine Information Center’s vaccine conference in early October. The NVIC is the oldest and biggest antivaccine organization there is. Either he didn’t know that, in which case he’s clueless, or he didn’t care. In any case, it was clear that he was invited there because of his stance on flu vaccination, and he was even going to be awarded the NVIC “Courage in Science” Award. To his credit, Jefferson backed out when he found out that he would be sharing the stage with Andrew Wakefield, who was to be given the NVIC “Humanitarian Award.” He was appropriately horrified. Still, he should never have accepted in the first place, given that the NVIC clearly wanted to coopt him and use his gadfly status to make its anti-vaccine stance seem reasonable and science-based.
That’s just one reason why I don’t take Tom Jefferson particularly seriously anymore. I tend to agree with revere that Jefferson is drifting perilously close to crank territory with respect to flu vaccines. Indeed, “methodolatry” is an awesome term to describe his approach. Actually, it’s a great term to describe some of the Cochrane scientists responsible for analyzing the efficacy of mammography screening, as well; their conclusions and methods rather remind me of Jefferson’s.
Finally, you might also want to reread (or read for the first time if you haven’t read it already) Mark Crislip’s article on flu vaccine efficacy, which, although not directly written in response to Brownlee’s article, does address many of the shortcomings in its analysis of H1N1 vaccine efficacy.
I was making rounds at the hospital and, for some strange reason, I was being asked about influenza. No, this is not going to be an entry on influenza. But I was asked if there was anything besides the vaccines that can prevent influenza. Masks and good hand washing will help, I said.
A nurse suggested colloidal silver.
I’m taking this opportunity to introduce a new blog to the SBM audience, and to draw yet more attention to the growing and dangerous trend of parental vaccine refusal. So, please take a momentary break from your perusal of this most esteemed font of knowledge, and point your browser to Gotham Skeptic.
A recent study published in the journal Complementary Therapies in Medicine shows no benefit from copper or magnetic bracelets for symptomatic treatment of arthritis. While this is a relatively small study, it highlights the lack of evidence to support this billion dollar plus industry.
The study is a double-blind, controlled crossover study involving 45 subjects with osteroarthritis. Each subject wore one of four bracelets – copper, two types of magnetic bracelet, and one demagnetized, in random order each for 16 weeks. It showed no difference among the four groups.
This is only the second published controlled trial looking at copper bracelets for arthritis. The first is from 1976 and showed some benefit. Then there are no published studies (just reviews and comments) for the next 33 years, until this current study.
The past two months have been my first time working in the hospital, as a third-year medical student in my Internal Medicine clerkship. It’s been exciting not only to see how medicine works but to be a part of the action! It really is striking to see the dramatic increases in proficiency and confidence with each stage of the training. From junior student to acting intern to intern to resident to chief resident and eventually to attending, each year brings both more responsibility and more competence. Importantly, physicians-in-training also get very efficient in seeking out and communicating information. Just like SBM editors read widely and blog prolifically whereas I struggle to put together one post a month, experienced clinicians have responsibility for dozens of patients at a time whereas I feebly tag along with one or two each day. Watching my elders on the medical team, I feel excited about how much smarter and more effective I will become as I progress through my training.
Anyway, I want to share an interesting sight in my hospital last month. There were three 3-foot posters on tripods prominently displayed in the hospital lobby, in the cafeteria, and in other public places. The first one read: (more…)
Dr. Weil is often seen as the smiling “mainstream” of alternative medicine. He’s a real doctor (unlike, say, Gary Null), and much of what he advocates is standard and uncontroversial nutritional advice. But Weil illustrates the two biggest problems with so-called alternative medicne: once you’ve decided science is dispensible, the door is open to anything, no matter how insane; and no matter how altruistic you may start, sooner or later you start selling snake oil. Most doctors out there are working hard to help their patients prevent and overcome disease use the available evidence. Others decide that science is too constraining and start practicing at the periphery of knowledge, throwing plausibility and ethics to the wind.
The fact that Weil claims to donate to charity all of his ill-gotten gains does not mitigate the harm he causes.
The flu pandemic has been challenging to all of us who practice medicine. We try to keep up day to day with the latest numbers, evidence, and best practices, while trying not to worry about getting ill. And since the vaccine isn’t widely available yet, we also worry about our family’s health. So we go about our work every day, wearing masks when appropriate and washing hands frequently. If the numbers reach a certain threshold, we will implement sophisticated pandemic plans.
All of that is rather hard, though, so perhaps we should just throw caution to the wind and start selling flu snake oil just like the smiling Dr. Weil.
The FDA and FTC have let Weil know in very clear terms that his fake flu remedies are being marketed illegally. Weil has taken the site down, but here’s a relevant screen shot.
Oh Canada. Look over here. Not there. Not at the press release. Look here. A real study. Published. With methodologies you can evaluate. Something you can sink your teeth into to help guide policy decisions. You know, published epidemiology. Science.
Its called “Partial protection of seasonal trivalent inactivated vaccine against novel pandemic influenza A/H1N1 2009: case-control study in Mexico City.” and published on line in the BMJ on October 6th.
Are you aware of….Oh, Canada, pay attention, your eyes are wandering.
