Suzanne Somers’ Knockout: Dangerous misinformation about cancer (part 1)

If there’s one thing I’ve become utterly disgusted with in the time since I first became interested in science-based medicine as a concept, its promotion, and the refutation of quackery and medical pseudoscience, it’s empty-brained celebrities with an agenda. Be it from imbibing the atmosphere within the bubble of woo-friendly southern California or taking a crash course at the University of Google and, through the arrogance of ignorance, concluding that they know more than scientists who have devoted their lives to studying a problem, celebrities believing in and credulously promoting pseudoscience present a special problem because of the oversized soapboxes they command. Examples abound. There’s Bill Maher promoting anti-vaccine pseudoscience, germ theory denialism, and cancer quackery on his show Real Time with Bill Maher and getting the Richard Dawkins Award from the Atheist Alliance International in spite of his antiscience stances on vaccines and what he sneeringly calls “Western medicine.” Then there are, of course, the current public faces of the anti-vaccine movement, Jenny McCarthy and her boyfriend Jim Carrey, the former of whom thinks it’s just hunky dory (or at least doesn’t appear to be the least bit troubled) that her efforts are contributing to the return of vaccine-preventable infectious diseases because she apparently thinks that’s what it will take to make the pharmaceutical companies change their “shit” product (her words), and the latter of whom spreads conspiracy theories about vaccines and contempt on people suffering from restless leg syndrome. Finally, there’s the grand macher of celebrity woo promotion, Oprah Winfrey, who routinely promotes all manner of medical pseudoscience, be it “bioidentical” hormones, the myth that vaccines cause autism (even hiring Jenny McCarthy to do a blog and develop a talk show for her company Harpo Productions), or other nonsense, such as Christiane Northrup urging Oprah viewers to focus their qi to their vaginas for better sex.

Unfortunately, last week the latest celebrity know-nothing to promote health misinformation released a brand new book and has been all over the airwaves, including The Today Show, Larry King Live, and elsewhere promoting it. Yes, I’m talking about Suzanne Somers, formerly known for her testimonial of having “rejected chemotherapy and tamoxifen” for her breast cancer, as well as her promotion of “bioidentical hormones,” various exercise devices such as the Thighmaster and all manner of supplements. Her book is entitled Knockout: Interviews with Doctors Who Are Curing Cancer–And How to Prevent Getting It in the First Place. It is described on the Random House website thusly:

“Methodolatry”: My new favorite term for one of the shortcomings of evidence-based medicine

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.

Journalist fails but science wins during flu pandemic

The Atlantic has a monumentally horrible article up about flu vaccination which has been buzzing around our bloggy back channels. There has been some good science reporting out there lately, but this ain’t it. I was hoping one of the best public health blogs would jump on this, and jump on it they did.  It is a terrific example of how to approach difficult data in the heat of a pandemic. This is your reading assignment for the weekend, and you can probably finish up before the Michigan game.  Go and read (and Go Blue!).

Hi Ho Silver

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.

Anything else?

A nurse suggested colloidal silver.

A Case Study In Aggressive Quackery Marketing

With some degree of sadness I recently “outed” a former co-resident of mine who has turned to the dark side and begun putting money-making before truth and science. Without any clear evidence of benefit beyond placebo, platelet-rich plasma (PRP) is now being marketed aggressively as a cure-all for sports injuries. And at about $300 per injection (the NYT reports $2000/treatment), there’s plenty of money to be made.

Like the fake “stem cell” clinics in Russia (where, according to Sanjay Gupta’s recent book, Chasing Life, a person’s fat cells are harvested, washed, and re-injected into their blood stream), PRP also involves injection of autologous body fluids. Essentially, a small amount of blood is drawn from the patient, centrifuged, and the plasma supernatant is then injected directly into tendons and/or joints. After a series of 3 injections (one/month), most sports injuries are “cured.” Of course, most injuries would heal themselves in three months anyway. (more…)

The New Plague

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.

Copper and Magnetic Bracelets for Arthritis

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.

Mixed Messages on Campus

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…)

The Montagnier “Homeopathy” Study

A recent study is being cited as support for homeopathy. For instance, the Homeopathy World Community website says

Luc Montagnier Foundation Proves Homeopathy Works.

Dana Ullman cites it in the comments to this blog

And I assume that you all have seen the new research by Nobel Prize-winning virologist Luc Montagnier that provides significant support to homeopathy. 

Nope. Sorry, guys. It doesn’t. In fact, its findings are inconsistent with homeopathic theory.

The study has nothing whatsoever to say about homeopathy. Its abstract concludes:

This opens the way to the development of highly sensitive detection system for chronic bacterial infections in human and animal diseases.

Homeopaths are grasping at straws when they cite this study. It involved dilution and agitation: that’s the only possible hint of anything homeopathic and it is nothing but a false analogy. (more…)

An epidemic of fear: The anti-vaccine movement’s war on science

We’ve often castigated the press and mainstream media for getting it so very, very wrong on the issue of vaccines and autism and its all-too-often credulous treatment of the anti-vaccine movement. That’s very important. However, it’s also equally important to recognize mainstream media outlets when they get it so very, very right. That’s why, with minimal fanfare, I’m simply going to refer you to an article in WIRED Magazine entitled An Epidemic of Fear: How Panicked Parents Skipping Shots Endangers Us All by Amy Wallace. I particularly like Wallace’s calling out some prominent anti-vaccine activists, such as Jenny McCarthy, Jim Carrey, Don Imus, and Robert F. Kennedy, Jr.

Bravo, Ms. Wallace. Bravo, WIRED.

Go. Read. While you’re at it, you might want to lend some tactical air support to the cause of science and reason in the comments section. As they always do, the anti-vaccine kooks have already descended.
