Acupuncture, Infertility, and Horrible Reporting

An article (and associated news video clip) from ClickOn in Detroit is titled “Alternative treatment helps Michigan doctor beat infertility.” This is a misleading title, and the report is an example of poor science reporting.

Was She Infertile?

The patient in question was a 33-year-old family practice doctor who believed she was infertile. By definition, infertility is failure to conceive after a year of regular intercourse without contraception. She didn’t meet that definition. She only tried for 6 months before seeing a doctor, and then for 2 more months (with some kind of unspecified medicine) and then she consulted a reproductive endocrinologist who apparently told her she was infertile because of a high FSH level. Then she “did her own research” and supposedly found that acupuncture was a key part of infertility treatment. So she sought infertility treatment from an acupuncturist.

NIH Director Francis Collins doesn’t understand the problem with CAM

As the sole cancer surgeon among our stable of Science-Based Medicine (SBM) bloggers, I’m probably the most irritated at the infiltration of pseudoscience into academia (or, as we sometimes like to call it, quackademic medicine) in the realm of cancer. Part of the reason, of course, is that cancer is so common and that the consequences of adding pseudoscience to cancer therapy are among the most devastating. Witness, for instance, the use of Gonzalez therapy to treat pancreatic cancer, a form of quackery that harms patients and resulted in incredibly unethical and disastrous clinical trial of Gonzalez quackery versus chemotherapy whose results were entirely predictable, given the lack of prior plausibility of the treatment: Gonzalez protocol patients did worse, with no evidence that the therapy impacted the natural history of the disease and the Gonzalez patients scoring lower on quality of life measures. Or look at what happens when patients with breast cancer choose quackery over science-based therapy.

I realize that “complementary and alternative medicine” (CAM) or, what quackademics like to call it now, “integrative medicine” (IM) is meant to refer to “integrating” alternative therapies into SBM or “complementing” SBM with a touch of the ol’ woo, but I could never manage to understand how “integrating” quackery with SBM would do anything but weaken the scientific foundation of medicine. Moreover, weakening those foundations would have more consequences than just “humanizing” medicine; weaker scientific standards would allow not just ancient quackery like traditional Chinese medicine (TCM) into academia, but it would also provide an opening for drug and device companies to promote their wares under less rigorous requirements for evidence. There’s also perhaps a touch of personal embarrassment involved. After all, oncology and cancer surgery tend to be specialties that are the most steeped in science. If I had to rank specialties for how science-based they are, I’d certainly put oncology near the top, which is why I tend to come down so hard on “integrative oncology” and, even worse, “naturopathic oncology.”

Consequently, I was doubly disturbed several months ago when I learned that the director of the National Institutes of Health, Francis Collins, had agreed to be the keynote speaker at the Eight International Society for Integrative Oncology Conference in Cleveland, OH. I say “doubly” disturbed because it disturbed me that Francis Collins would agree to speak at such a function and, perhaps even more, because the host institution was Case Western Reserve University, the institution where I both completed my surgery residency and my PhD in Physiology and Biophysics. Sadly, it now appears that my old stomping grounds at University Hospitals has been thoroughly infiltrated with quackademic medicine, as evidenced by this clinical trial of reiki for psoriasis that’s making the rounds of news services and the offering of acupuncture, reiki, and even reflexology at various UH facilities through the University Hospitals Connor Integrative Medicine Network. Let me tell you, there was none of this pseudoscience going on when I finished my residency there in 1996. Seeing it there now provokes a reaction in me not unlike Sylvester Junior’s reaction when his father Sylvester embarrasses him, particularly when I noted that the director of the CWRU Comprehensive Cancer Center, Dr. Stanton L. Gerson, was to give one of the keynote talks, entitled, “The Future of Integrative Oncology.” (Hint for those of you not familiar with classic Looney Tunes cartoons: A paper bag is involved.) I guess that by expressing my extreme disappointment and embarrassment that the institution where I learned to become a surgeon has during the last 15 years gone woo, I’ve probably just killed any opportunity I might have to work at the Case Comprehensive Cancer Center ever again. Oh, well, add it to the list, along with Beth Israel and my alma mater the University of Michigan.)

Back when I first learned about it, I thought about blogging the meeting, but without much concrete to go on, given the copious other SBM-related topics to blog about, all I could do was to write a critical open letter to Dr. Collins about his decision to accept the offer to be the keynote speaker at the Society for Integrative Oncology (SIO). Then yesterday I saw popping up in my e-mail a notice from the American Society of Clinical Oncology (ASCO), along with a link to a story in its publication The ASCO Post entitled NIH Director Calls for Rigorous Evaluation of Integrative Medicine to Provide Evidence of Efficacy.

Et tu, Dr. Collins?

Acupuncture, the Navy, and Faulty Thinking

A Navy neurologist, Capt. Elwood Hopkins, has posted a 3-part article on  “The Power of Acupuncture” on Navy Medicine Live, the official blog of Navy and Marine Corps Health Care. It can serve as a useful lesson in how not to think about medicine. It is a prime example of how an intelligent, educated doctor can be fooled and can fool himself into thinking that a placebo is an effective treatment.

To set the scene: acupuncture has been increasingly accepted in military circles. The Air Force is teaching its doctors “battlefield acupuncture” based on the faulty evidence of one Air Force doctor, Richard Niemtzow.  The Army is using it to treat PTSDThe Navy offers it too.

Hopkins says that after 40 years of practicing neurology, “It was only natural to begin thinking about something else.” (Why? Boredom? And why pick acupuncture?) When he got an e-mail from his Specialty Leader announcing the opportunity for Navy doctors to learn how to do acupuncture, he submitted his application that same day. He was undoubtedly impressed that this training was being offered by the Navy, lending it the imprimatur of authority. His prior impression of acupuncture was that it was a “mysterious tool” that seemed to work; and instead of asking critical questions, he says he was looking for “a fundamental scientific understanding of acupuncture” and asking to see the supporting research and data.  (more…)

Lessons Learned

I just returned from a trip to Montreal where I spoke at the Lorne Trottier Public Science Symposium, an annual event that David Gorski spoke at a year ago. My topic was “Puncturing the Acupuncture Myth” and the other speakers were Paul Offit, Edzard Ernst, and Bob Park. I was honored to be in such august company; and we were wined, dined, and cossetted: overall, an experience that will count among the high points of my career. In addition to speaking at the Symposium, I was interviewed on the radio; participated in a roundtable discussion with other doctors, scientists and journalists; and was invited to speak to a large freshman chemistry class at McGill University. I told the students a bit about how I came to be the SkepDoc and some of the things I’ve written about, with “Vitamin O” as an example, and I provided 3 “lessons I have learned” from my investigations that are general principles applicable to other fields:

  • Roosters don’t make the sun come up.
  • Never believe one study.
  • The SkepDoc’s Rule of Thumb: when encountering a new or questionable claim, always try to find out who disagrees and why.

My presentation was recorded and is available as a webcast. Scroll down to “2011/11/08 HallOffit” near the bottom and click on the appropriate symbol to the far right. That saves me having to write a post this week. I think SBM readers will find it pertinent to all we discuss here.

Dummy Medicine, Dummy Doctors, and a Dummy Degree, Part 2.3: Harvard Medical School and the Curious Case of Ted Kaptchuk, OMD (concluded)

Dummy Medicine, Dummy Doctors, and a Dummy Degree, Part 2.3: Harvard Medical School and the Curious Case of Ted Kaptchuk, OMD (concluded)

A Loose End

In the last post I wondered if Ted Kaptchuk, when he wrote the article titled “Effect of interpretive bias on clinical research,” had understood this implication of Bayes’s Theorem: that interpretations of most scientific investigations are exercises in inverse probability, and thus cannot logically be done without consideration of knowledge external to the investigation in question. I argued that if Kaptchuk had

…understood the point when he wrote his treatise, he was dishonest in not explaining it and in not citing at least one pertinent article, such as Steven Goodman’s (which I’m willing to bet he had read). If he didn’t understand the point he should have withheld his paper.

In researching more of Kaptchuk’s opinions I’ve discovered that he had certainly read Goodman’s article, but that he either didn’t understand it or preferred to obscure its implications in deference to his ongoing project in belittling scientific knowledge. In a letter to the editor of the Annals of Internal Medicine in 2001, Kaptchuk opined that even if “more trials of distant healing with increased methodologic rigor” were positive, it still would not “be persuasive for the medical community”:

The situation resembles the predicament with homeopathy trials, another seemingly implausible intervention, where the evidence of multiple positive randomized, controlled trials will not convince the medical community of its validity. Additional positive trials of distant healing are only likely to further expose the fact that the underpinning of modern medicine is an unstable balance between British empiricism (in the tradition of Hume) and continental rationalism (in the tradition of Kant).

…It seems that the decision concerning acceptance of evidence (either in medicine or religion) ultimately reflects the beliefs of the person that exist before all arguments and observation. [Kaptchuk cites the second of the two Goodman articles that I referred to above, discussed here]

“And one more thing” about Steve Jobs’ battle with cancer

I’ve written quite a bit about Steve Jobs in the wake of his death nearly four weeks ago. The reason, of course, is that the course of his cancer was of intense interest after it became public knowledge that he had cancer. In particular, what I most considered to be worth discussing was whether the nine month delay between Jobs’ diagnosis and his undergoing surgery for his pancreatic insulinoma might have been what did him in. I’ve made my position very clear on the issue, namely that, although Jobs certainly did himself no favors in delaying his surgery, it’s impossible to know whether and by how much he might have decreased his chances of surviving his cancer through his flirtation with woo. However much his medical reality distortion field might have mirrored his tech reality distortion field, my best guess was that Jobs probably only modestly decreased his chances of survival, if that. I also pointed out that, if more information came in that necessitated it I’d certainly reconsider my conclusions.

The other issue that’s irritated me is that the quackery apologists and quacks have been coming out of the woodwork, each claiming that if only Steve Jobs had subjected himself to this woo or taken this supplement, he’d still be alive today. Nicholas Gonzalez was first out of the gate with that particularly nasty, unfalsifiable form of fake sadness, but he wasn’t the only one. Recently Bill Sardi claimed that there are all sorts of “natural therapies” that could have helped Jobs, while Dr. Robert Wascher, MD, a surgical oncologist from California (who really should know better but apparently does not) claims that tumeric spice could have prevented or cured Steve Jobs’ cancer, although in all fairness he also pointed out that radical surgery is currently the only cure. Unfortunately, he also used the failure of chemotherapy to cure this kind of cancer as an excuse to call for being more “open-minded” to alternative therapies. Even Andrew Weil, apparently stung by the speculation that Jobs’ delay in surgery to pursue quackery might have contributed to his death, to tout how great he thinks integrative cancer care is.

Last week, Amazon.com finally delivered my copy of Walter Isaacson’s biography of Steve Jobs. I haven’t had a chance to read the whole thing yet, but, because of the intense interest in Jobs’ medical history, not to mention a desire on my part to see (1) if there were any new information there that would allow me to assess how accurate my previous commentary was and (2) information that would allow me to fill in the gaps in the story from the intense media coverage. So I couldn’t help myself. I skipped ahead to the chapters on his illness, of which there are three, entitled Round One, Round Two, and Round Three. Round One covers the initial diagnosis. Round Two deals with the recurrence of Jobs’ cancer and his liver transplant. Finally, Round Three deals with the final recurrence of Jobs’ cancer, his decline, and death.

Before I start, a warning: I’m going to discuss these issues in a fair amount of detail. If you want “medical spoilers,” don’t read any further. On the other hand, one spoiler I will mention is that there was surprisingly little here that wasn’t reported before; the only difference is that there is more detail. However, the details are informative.

Dummy Medicine, Dummy Doctors, and a Dummy Degree, Part 2.2: Harvard Medical School and the Curious Case of Ted Kaptchuk, OMD (cont. again)

“Strong Medicine”: Ted Kaptchuk and the Powerful Placebo

At the beginning of the first edition of The Web that has no Weaver, published in 1983, author Ted Kaptchuk portended his eventual academic interest in the placebo:

A story is told in China about a peasant who had worked as a maintenance man in a newly established Western missionary hospital. When he retired to his remote home village, he took with him some hypodermic needles and lots of antibiotics. He put up a shingle, and whenever someone came to him with a fever, he injected the patient with the wonder drugs. A remarkable percentage of these people got well, despite the fact that this practitioner of Western medicine knew next to nothing about what he was doing. In the West today, much of what passes for Chinese medicine is not very different from the so-called Western medicine practiced by this Chinese peasant. Out of a complex medical system, only the bare essentials of acupuncture technique have reached the West. Patients often get well from such treatment because acupuncture, like Western antibiotics, is strong medicine.

Other than to wonder if Kaptchuk had watched too many cowboy ‘n’ Native American movies as a kid, when I first read that passage I barely blinked. Although the Chinese peasant may have occasionally treated someone infected with a bacterium susceptible to his antibiotic, most people will get well no matter what you do, because most illnesses are self-limited. Most people feel better even sooner if they think that someone with special expertise is taking care of them. If you want to call those phenomena the “placebo effect,” in the colloquial sense of the term, fine. That, I supposed, was what Kaptchuk meant by “strong medicine.”

Turns out I was mistaken. Let’s briefly follow Kaptchuk’s career path after 1983. In the 2000 edition of The Web, he wrote:

Dummy Medicine, Dummy Doctors, and a Dummy Degree, Part 2.1: Harvard Medical School and the Curious Case of Ted Kaptchuk, OMD (cont.)

Rave Reviews

In 1983, Ted Kaptchuk, the senior author of the recent “albuterol vs. placebo” article, and soon to become the long-time Second-in-Command of the Harvard Medical School “CAM” program, published The Web that Has No Weaver:

The book received rave reviews:

A major advance toward the synthesis of Western and Eastern theory. It will stimulate all practitioners to expand their understanding of the causes and treatment of disease.

–Paul Epstein, MD, Harvard Medical School

A lucid and penetrating exposition of the theory and practice of Chinese medicine. While the book’s rich detail makes it of great use to practicing healers, it is in its entirety very simply written, enjoyable reading for the layman…it brings a demystifying balance…Instructive, profound, and important!

Professor Martin Schwartz, University of California, Berkeley

…demystifies Oriental medicine in a remarkably rational analysis…

—Science Digest, Nov. 1982

…an encyclopedia of how to tell from the Eastern perspective ‘what is wrong.’

Larry Dossey

Dr. Kaptchuk has become a lyricist for the art of healing…

—Houston Chronicle

Although the book is explicitly detailed, it is readable and does not require previous knowledge of Chinese thought…

—Library Journal

The 2nd edition was published in 2000, to more acclaim:

…opens the great door of understanding to the profoundness of Chinese medicine.

—People’s Daily, Beijing, China

…weaves a picture…that is eminently understandable from a Westerner’s point of view…adds a valuable analysis of the current scientific understanding of how the therapies work and their effectiveness.

Brian Berman

Ted Kaptchuk’s book was inspirational in the development of my acupuncture practice and gave me a deep understanding of traditional Chinese medicine…

Dr. George T. Lewith

…a gift for all who share an interest in deep understanding of healing. This new edition is essential reading…

Michael Lerner, President, Commonweal

Even Edzard Ernst, still in his foggy period, called the 2nd edition “a brilliant synthesis of traditional and scientific knowledge…compulsory reading…”

Dummy Medicine, Dummy Doctors, and a Dummy Degree, Part 2.0: Harvard Medical School and the Curious Case of Ted Kaptchuk, OMD

Review

The recent albuterol vs. placebo trial reported in the New England Journal of Medicine (NEJM) found that experimental subjects with asthma experienced substantial, measured improvements in lung function after inhaling albuterol, but not after inhaling placebo, undergoing sham acupuncture, or “no treatment.” It also found that the same subjects reported having felt substantially improved after either albuterol or each of the two sham treatments, but not after “no treatment.” Anthropologist Daniel Moerman, in an accompanying editorial, wrote, “the authors conclude that the patient reports were ‘unreliable,’ since they reported improvement when there was none”—precisely as any rational clinician or biomedical scientist would have concluded.

In Part 1 of this blog we saw that Moerman took issue with that conclusion. He argued, with just a bit of hedging, that the subjects’ perceptions of improvement were more important than objective measures of their lung function. I wondered how the NEJM editors had chosen someone whose bibliography predicted such an anti-medical opinion. I doubted that Editor-in-Chief Jeffrey Drazen, an expert in the pathophysiology of asthma, had ever heard of Moerman. I suggested, in a way that probably appeared facetious, that Ted Kaptchuk, the senior author of the asthma report, might have recommended him. (more…)

What to Expect When You’re Expecting

A correspondent asked me to review the book What to Expect When You’re Expecting by Heidi Murkoff and Sharon Mazel. She wrote “I’m very worried about this book.”

She had just seen an NPR article about the book and was alarmed because it provided an excerpt from the book recommending that patients with morning sickness “Try Sea-Bands” and “Go CAM Crazy.” She knew from reading SBM and other science blogs that “going CAM crazy” is not a good idea. She was savvy enough to search Google Books with the title and “CAM” and found more alarming advice(more…)
