The Skeptical O.B. joins the Science-Based Medicine crew

I’m very pleased to announce that Dr. Amy Tuteur, otherwise known as The Skeptical O.B., has joined Science-Based Medicine. Dr. Tuteur will fill in an area where we are lacking, namely an expert in women’s health and childbirth. For those of you who don’t know Dr. Tuteur, she is an obstetrician-gynecologist. She received her undergraduate degree from Harvard College and her medical degree from Boston University School of Medicine. Dr. Tuteur is a former clinical instructor at Harvard Medical School. Her book, How Your Baby Is Born, an illustrated guide to pregnancy, labor and delivery was published by Ziff-Davis Press in 1994. She runs the website AskDrAmy.com and has her own iPhone app, the Ask Dr. Amy Am I Pregnant Quiz. Dr. Tuteur blogs at The Skeptical OB.

We expect great things from Dr. Tuteur, and hope you will join us in welcoming her to the fold. She will begin tomorrow and will post new material every Thursday. Finally, with the addition of Dr. Tuteur, it should also be noted that, due to the demands of her day job, Dr. Val Jones will decrease her posting frequency from every Thursday to every other Thursday. She will thus not be posting this week, and her next post will be on Thursday, November 12.

The cancer screening kerfuffle erupts again: “Rethinking” screening for breast and prostate cancer

I see that the kerfuffle over screening for cancer has erupted again to the point where it’s found its way out of the rarified air of specialty journals to general medical journals and hence into the mainstream press.

Over the last couple of weeks, articles have appeared in newspapers such as the New York Times and Chicago Tribune, radio networks like NPR, and magazines such as TIME Magazine pointing out that a “rethinking” of routine screening for breast and prostate cancer is under way. The articles bear titles such as A Rethink On Prostate and Breast Cancer Screening, Cancer Society, in Shift, Has Concerns on Screenings, Cancers Can Vanish Without Treatment, but How?, Seniors face conflicting advice on cancer tests: Benefit-risk questions lead some to call for age cutoffs, and Rethinking the benefits of breast and prostate cancer screening. These articles were inspired by an editorial published in JAMA last month by Laura Esserman, Yiwey Shieh, and Ian Thompson entitled, appropriately enough, Rethinking Screening for Breast Cancer and Prostate Cancer. The article was a review and analysis of recent studies about the benefits of screening for breast and prostate cancer in asymptomatic populations and concluded that the benefits of large scale screening programs for breast cancer and prostate cancer tend to be oversold and that they come at a higher price than is usually acknowledged.

For regular readers of SBM, none of this should come as a major surprise, as I have been writing about just such issues for quite some time. Indeed, nearly a year and a half ago, I first wrote The early detection of cancer and improved survival: More complicated than most people think. and then followed it up with Early detection of cancer, part 2: Breast cancer and MRI. In these posts, I pointed out concepts such as lead time bias, length bias, and stage migration (a.k.a. the Will Rogers effect) that confound estimates of benefit due to screening. (Indeed, before you continue reading, I strongly suggest that you go back and read at least the first of the aforementioned two posts to review the concepts of lead time bias and length bias.) Several months later, I wrote an analysis of a fascinating study, entitling my post Do over one in five breast cancers detected by mammography alone really spontaneously regress? At the time, I was somewhat skeptical that the number of breast cancers detected by mammography that spontaneously regress was as high as 20%, but of late I’m becoming less skeptical that the number may be somewhere in that range. Even so, at the time I did not doubt that there likely is a proportion of breast cancers that do spontaneously regress and that that number is likely larger than I would have guessed before the study. Of course, the problem is that we do not currently have any way of figuring out which tumors detected by mammography will fall into the minority that do ultimately regress; so we are morally obligated to treat them all. My most recent foray into this topic was in July, when I analyzed another study that concluded that one in three breast cancers detected by screening are overdiagnosed and overtreated. That last post caused me the most angst, because women commented and wrote me asking me what to do, and I had to answer what I always answer: Follow the standard of care, which is yearly mammography over age 40. This data and these concerns have not yet altered that standard of care, and I am not going to change my practice or my general recommendations to women until a new consensus develops.

When homeopaths attack medicine and physics

I must admit, it is possible that our fearless leader Steve has a more robust constitution than I do. I say this because he actually managed to sit through an entire video full of the most bizarre pseudoscience and mangling of physics and medicine that I’ve seen in quite some time.

And that’s saying a lot.

So, behold, Dr. Charlene Werner, an optometrist (apparently) and a homeopath. I warn you, however. If you have any understanding of physics or chemistry whatsoever or if you’ve ever read (and liked) Stephen Hawking’s book A Brief History of Time (or anything else he’s ever written), sit down now. Take a deep breath. Heck, crack open a bottle of wine and down at least half of it before you watch this video. I’m serious. You’ll need it. You might need to lie down, too. In fact, you might need to lie down with a cool washcloth across your eyes.

Don’t say I didn’t warn you:

Truly, the woo doth flow. Like a river. Like the energy from a supernova. From Bozeman, Montana, where, apparently they don’t have enough woo and have to import it from Texas. I haven’t seen such a massive pseudoscientific abuse of physics and chemistry in quite a long time.

J.B. Handley of the anti-vaccine group Generation Rescue: Misogynistic attacks on journalists who champion science

There’s been something I’ve been meaning to write about all week, but only just got around to it. There were lots of other things going on at my other online locale, and this topic is such old hat for so many that I really wasn’t sure if it was worth bothering with. My reluctance may also be, sadly, because I’ve become a bit jaded at the nastiness that anti-vaccine groups such as Generation Rescue (i.e., “Jenny McCarthy and Jim Carrey’s Autism Organization”–at least these days) and its erstwile founder J.B. Handley routinely lay down when someone points out that the emperor has no clothes, that vaccines do not cause autism. I’m referring, of course, to Amy Wallace, who wrote what is the best example of an article in the mainstream media about the anti-vaccine movement that “gets it.” The article was called An Epidemic of Fear: How Panicked Parents Skipping Shots Endangers Us All and appeared in WIRED Magazine.

It was a thing of beauty. There was no false “balance” that puts cranks pushing dangerous pseudoscience on the same plane as real scientists like Paul Offit. There was even a section calling out purveyors of vaccine misinformation. Several luminaries of the the anti-vaccine movement were there, including ones discussed frequently on this blog, like Jenny McCarthy and Jim Carrey, and Robert F. Kennedy, Jr. But that wasn’t all! There was even a section on how to debunk anti-vaccine canards. What more could an advocate of science-based medicine ask for?

Join CFI in opposing funding mandates for quackery in health care reform

Not long ago, I wrote a post warning about how funding for non-science-based modalities and, indeed, modalities that are purely religion-based, have found their way into various versions of health care reform bills that are currently wending their way through both houses of Congress. In other words, purveyors of faith healing and purely religious woo are trying to do what purveyors of “alternative” medicine have already done through Senator Tom Harkin, and hijack the health care reform process to codify their preferred unscientific health care modalities as legitimate after science has rejected them.

Now, the Center for Inquiry has launched a campaign to inform and educate our legislators. You can participate by using its talking points (or paraphrasing them or voicing your own objections) to protest:

Congress is considering health care legislation that would in part mandate coverage of non-evidenced based medical treatments such as prayer and therapeutic touch. This would raise the cost of health care for all Americans and represent a violation of the principle of separation of church and state.

CFI continues:

The Center for Inquiry asks you to contact your Senators and Representative to voice your strong opposition to the proposal in the Heath Care bills that would mandate coverage of non evidence-based “alternative” medical treatments including spiritual and prayer based healing under the guise of nondiscrimination.

Talking Points

  • America needs a health care system that focuses on increasing the health of individuals and reducing the cost of coverage.
  • This type of health care system is not possible if insurers are required to pay for medical treatments with questionable at best results.
  • If Congress requires that insurers cover alternative treatments such as Christian Science prayer, therapeutic touch, or other non-evidence based medical procedures, the cost of health care for all Americans will go up. This runs counter to the goal that Congress has laid out: to make health care more affordable for all Americans. – If the final version of health care reform includes a public option, this mandate would also force the public insurance plan to cover these treatments. Because the public option is federally funded, the inclusion of the mandate would represent an egregious violation of the principle of separation of church and state.

I agree. It’s time to try to stop the insertion of faith-based quackery like Christian Science “prayer” treatments as reimbursable medical expenses in whatever health care reform bill(s) is/are passed by Congress. You can help by going here and writing to your Congressional representatives and Senators.

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.

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.

Beware religious meddling in the latest version of health care reform

Every so often, as the health care reform initiative spearheaded by the Obama Administration wends its way through Congress (or, more precisely, wend their ways through Congress, given that there are multiple bills coming from multiple committees in both Houses), I’ve warned about various chicanery from woo-friendly legislators trying to legitimize by legislation where they’ve failed by science various “alternative” medicine practices. This began much earlier this year, when I pointed out how Senator Tom Harkin (D-IA) invited the Four Horsemen of the Woo-pocalypse to the Senate to testify. These included Dr. Andy Weil, Director, Arizona Center for Integrative Medicine, University of Arizona, Vail, AZ; Dr. Dean Ornish, Founder and President, Preventive Medicine Research Institute, Sausalito, CA; Dr. Mark Hyman, Founder and Medical Director, The UltraWellness Center, Lenox, MA; Dr. Mehmet C. Oz, Director, Cardiovascular Institute and Complementary Medicine Program, New York-Presbyterian Hospital, New York, NY. This occurred after Harkin had famously complained about the National Center for Complementary and Alternative Medicine, the Center in the NIH that he, more than anyone else, had created, because it had not validated enough quackery. (Yes, I know he didn’t use those words, but that was what he had done.) Most recently, Harkin tried to insert language that would mandate that the government and health insurers pay for quackery, as long as it was from licensed practitioners. Given that some states license naturopaths and even “homeopathic physicians,” such an amendment, if it stayed in place, would open the way for paying for all manner of nonscientific quackery.

However, there is another bit of chicanery that legislators are pulling, this time with the Senate version of the bill, that I have been made aware of by Rita Swan of CHILD and fellow SBM blogger Kimball Atwood. This time, the threat is religious, with Senators trying to insert measures into the health care reform initiatives that will pay for “religious” treatments, such as Christian Science prayer. Indeed, one of these, S.1679, entitled Affordable Health Choices Act requires the government or private party insurers to pay for faith-based therapies:

“Oh, come on, Superman!” (Part II): Bill Maher meets Kryptonite over vaccines and “Western medicine”

It’s rather amazing how sometimes the best laid plans of mice and men (and bloggers) come to naught. I had planned on doing a followup post to my previous post about the cancer quackery known as the German New Medicine by discussing a particularly nasty French variant of it. Unfortunately (or fortunately, depending upon your point of view), events conspired to move my blogging ire towards another target, particularly since I had addressed this isse before. Specifically, I’m talking about 2009 Recipient of the Richard Dawkins Award, comedian and HBO talk show host Bill Maher.

As you may recall, about a month ago, I wrote a rather long post (par for the course for me, I know) detailing ad nauseam how Bill Maher not only embraces germ theory denialism, anti-vaccine nonsense, and alternative medicine, in particular his apparent belief that “aggregate toxicity” or the typical unnamed “toxins” that alternative medicine mavens are so fond of blaming most disease on or, as Maher likes to call it, the “poisons” that we are eating and otherwise exposed to every day, but has been preaching this pseudoscience since at least 2005. Maher then followed this up a mere week before receiving his award named after a famous scientist with a hideously irrational promotion of cancer quackery. At that point, I thought I was done with the topic, at least as far as this particular blog goes (others know that elsewhere I’ve not been so quiet). At least, I had intended not to deal with this again on SBM.

Unfortunately, Bill Maher had other ideas. This is the perfect description for how I felt having to blog about this again:

Yes, it fits, particularly after Maher Tweeted to his fans:

If u get a swine flu shot ur an idiot.
