Be careful what you wish for, Dr. Dossey, you just might get it

If there’s one thing about the so-called “complementary and alternative medicine” (CAM) movement that I’ve emphasized time and time again, it’s that its adherents have a definite love-hate relationship with science. They hate it because it is the single greatest threat to their beliefs system and the pseudoscience that underlies it. At the same time, they crave the legitimacy that science confers. They crave it not because they have any great love for science. Quite the contrary. It is simply that they recognize that science actually delivers the goods. Of course, they believe that they deliver the goods too, but they come to this belief not through science but rather through all the cognitive shortcomings and biases to which humans are prone, such as confusing correlation with causation, confirmation bias, not recognizing regression to the mean, and being fooled by the placebo effect. Whether it’s through a misunderstanding of science or less innocent reasons, they go to great lengths to torture it into superficially appearing to support their claims through a combination of cherry-picking of studies that seem to support them and misrepresenting ones that don’t, discussions of which abound right here in this very blog.

The other thing I’ve emphasized about the CAM movement is that, even more than scientific credibility, they crave legitimacy. To them, however, science is but one pathway to legitimacy, because, unlike practitioners of science-based medicine, they are more than willing to bypass science to obtain the legitimacy–or at least the appearance of the legitimacy–they so crave. If it means doing an end run around science by trying to hijack the Obama health insurance reform bill that is currently being negotiated to resolve the differences between the Senate and House versions, so be it. Indeed, earlier this year, I described how Senator Tom Harkin has tried to promote CAM through the National Center for Complementary and Alternative Medicine (NCCAM) and trying to insert provisions into the bill that would mandate that government-subsidized insurance exchanges pay for CAM. Meanwhile, prominent CAM advocates have been carpet-bombing the media with dubious arguments in support of CAM, as in when Deepak Chopra, Rustum Roy, Dean Ornish, and Andrew Weil teamed up in different combinations to promote the idea that CAM is all about “prevention” and that science-based medicine, in all its reductionistic evil, is nothing more than pushing pills.

They’re at it again.

Functional Medicine IV

When I started this series on Functional Medicine, David Gorski suggested looking at Mark Hyman’s web page, which I had seen months before, but thought did not reveal much. That was a wrong. It shows a lot, and I suggest bloggers et al review it.

So I decided on a fourth “functional medicine” (FM) installment, in search of what it FM really is. On the Mark Hyman web page and in his Public TV monolog fund-raiser,  Hyman follows a seven point outline of what he believes Fuctional Medicine (“FM”) is. If one follows the 7 “keys” as he writes, optimum health, “ultra-wellness” happens. Here are the points:

  1. Environmental inputs
  2. Inflammation
  3. Hormones
  4. Gut & digestive health
  5. Detoxification
  6. Energy/Mitochondria/Oxidative Stress
  7. Mind body

Healing Touch and Coronary Bypass

A study published in Alternative Therapies in Health and Medicine is being cited as evidence for the efficacy of healing touch (HT). It enrolled 237 subjects who were scheduled for coronary bypass, randomized them to receive HT, a visitor, or no treatment; and found that HT was associated with a greater decrease in anxiety and shorter hospital stays.

This study is a good example of what I have called “Tooth Fairy Science.” You can study how much money the Tooth Fairy leaves in different situations (first vs. last tooth, age of child, tooth in baggie vs. tooth wrapped in Kleenex, etc.), and your results can be replicable and statistically significant, and you can think you have learned something about the Tooth Fairy; but your results don’t mean what you think they do because you didn’t stop to find out whether the Tooth Fairy was real or whether some more mundane explanation (parents) might account for the phenomenon.

Homeocracy IV

In the three prior posts of this series I tried to analyze some of the defects in the randomized clinical rials (RCTs) of homeopathic remedies for childhood diarrhea. The first entry showed that the first two RCTs’ (done in Nicaragua) methods could not produce a meaningful result because of the way the RCTs were set up (methods.) The second entry showed that the results obtained in the first two trials were meaningless clinically even if assumed to have resulted from more legitimate methods. The same applied to the third trial in Nepal, analyzed in the third entry.

This entry  will suggest that the authors’ fourth paper (Jacobs J, Jonas WB, Jimenez-Perez M, Crothers D. Homeopathy for childhood diarrhea: combined results and metaanalysis from three randomized, controlled clinical trials.  Pediat Inf Dis J, 2005;22:229-234.)- a meta-analysis (MA) of the data from the three RCTs resulted in conclusions equally as meaningless as those of the three trials.

The MA authors – several of the same workers from the three RCTs – begin by agreeing that the data from the RCTs, taken individually, were of borderline significance:

In our previous three studies, we evaluated the use of individualized homeopathic treatment of childhood diarrhea … The results of the two larger studies (n = 81, n = 116) were just at or near level of statistical significance. Because all three studies followed the same basic study design , […] we analyzed the combined data from these three studies to obtain greater statistical power.  In addition we conducted a meta-analysis of effect-size difference […] to look for consistency of effects.

MAs and systematic reviews (SRs) are the two consensus methods for summarizing data from multiple individual studies. The inclusion and search methods of RCTs for SRs and MAs are similar, but the objectives of the two are a bit different, as are the forms of the reports.  In SRs, the results are summarized  in more in narrative form, whereas in MAs the data are treated mathematically and the results are defined in statistical terms.  Thus authors of SRs are freer to speculate on the degree of confidence that a method is effective based on what is shown by the numbers of positive and negative RCTs collected.  Authors of MAs usually limit their comments to what the mathematical formulation of the summarized data show.

Medical Propaganda Films

David Gorski suggested I expand on a comment I left recently on one of his November posts. His subject was the then new documentary movie, “A Beautiful Truth.“ “Truth” is about the Gerson method – the dietary deprivation cum coffee enema cancer treatment developed by Dr. Max Gerson, a refugeee from Germany I the 1930s. His daughter, Charlotte now runs the Gerson Institute in Tijuana, Mexico. Gerson is one of the models for the Gonzales method recently reviewed by Kim Atwood.

I had previously referred to the movie in a prior post (1) (but in a different context. Here I’ll explore the movie from a different angle – with its partners, propaganda documentaries.

David called my attention to “Truth” plus another by the same producer – with trailers on You Tube. When I watched the trailers last year I saw myself interviewed briefly, but could not recall being filmed, or even identify where the scene took place. I had to email Steve Barrett, also in the movie, who reminded me about filmmaker Steve Kroschel’s visits 2-3 years before, although neither did he have strong memory of the interview.

AARP and Alternative Medicine

I know I said the next entry would be about the efficacy of the influenza vaccine. The road to blogging in paved with good intentions. I will eventually write that entry, but the ADD has kicked in and my attention has wandered elsewhere.

I am 51 and one of the benefits of this advanced age is you get to join AARP, the American Association of Retired People. Yes, I know I am not retired, and given the current economic situation I am already practicing for my retirement.

“Do you what paper or plastic?”

“For here or to go?”

“Do you want fries with that?

Piece of cake. Who needs a 401K?

The day I received the AARP application, on my 50th birthday, despite some misgivings (8), I joined.

The purpose of AARP, besides discounts at Denny’s and the right to yell at kids when they are on your lawn, is, according to their mission statement, “AARP is dedicated to enhancing quality of life for all as we age. We lead positive social change and deliver value to members through information, advocacy and service. (1)” AARP is a lobby/special interest group for the elderly. In medicine the elderly are considered a vulnerable/at risk group. The elderly may have have fixed incomes, chronic medical problems, declining cognitive function and social situations that make them particularly susceptible to scams of all kinds. So it was nice to have an organization looking after our interests.

AARP has at least 40 million members. Accompanying the membership is their magazine, somewhat eponymously entitled AARP Magazine. The AARP Magazine has the largest circualtion of any magazine in the US with 24 million copies, each read issue by more than one person (7). It has 3 times the circulation of Readers digest. Only Parade magazine has a wider circulation. These are the publications where people receive casual information about about health care. I would assume that a magazine from my advocacy organization would contain information that I can trust. After all, AARP is looking out for my interests as a senior, and any article they would publish, especially relating to health and finances, I should be confident was reliable.

The January/February had an article “Drug Free Remedies for Chronic Pain” by Loolwa Khazzoom (2).

Biofeedback and Laser for Allergies

AllergiCare Relief Centers are a chain of franchises started by a man called David Tucker who is not listed as having an MD or any other title. They offer diagnosis of allergies by biofeedback and treatment of allergies by laser acupuncture. They admit that the method is not backed by any science, and they claim that what they are doing is not medical treatment.

Responsible journalism might have investigated this as quackery or practicing medicine without a license. Instead, irresponsible journalism has helped promote these centers and has given them invaluable free advertising.

From one news story:

Tucker said the device works based on biofeedback. The allergy sufferer wears a sensing clip on his finger for testing, and the computer simulates the bio-frequency for 10,000 known allergens. As the body responds to those stimuli, the computer lists which substances are irritants. “This digitized allergen actually matches the harmonic frequency of the actual allergen, making the body believe it is in contact with the real substance,” Tucker said. “The body will react if it is allergic to the particular substance.” ….Once the allergens are identified, a laser stimulates biomeridian points on the body — the same points used in acupuncture and acupressure. Tucker said the idea is to strengthen organs to act properly the next time they encounter the allergen — that is, to treat them as harmless…So far, there is no science to prove the devices work, but Tucker claims a 70 percent positive response rate.

Acupuncture for Hot Flashes – Or, Why So Many Worthless Acupuncture Studies?

In yet another round of science by press release, a particularly unimpressive acupuncture study is making the rounds of the major news outlets proclaiming that acupuncture works. I guess that is a sort-of answer to my title question – why are so many scientifically worthless acupuncture studies being done?

Let’s take a look at this particular study to see why it is so weak. All I have to go on is the press release, since the study is not published. It was presented at a scientific meeting – which is legitimate, I just don’t have access to it. (The bar for publication in a peer-reviewed journal is much higher than presentation at a meeting, and there may, in fact, be changes to the text prior to publication.) But we can still say a great deal about this study from the information provided.

“Patient-Centered Care” and the Society for Integrative Oncology

Should Medical Journals Inform Readers if a Book Reviewer can’t be Objective?

At the end of last week’s post I suggested that book reviewer Donald Abrams and the New England Journal of Medicine had withheld information useful for evaluating Abrams’ review: that he is the Secretary/Treasurer of the Society for Integrative Oncology (SIO), the organization of which Lorenzo Cohen, the first editor of the book that Abrams reviewed,* is President. I also promised to look at material from the book and from the Society’s website in order to discover “data that will allow even the most conventional oncologists to appreciate [the value of 'integrative' methods].”

There is little question that Abrams and Cohen know each other, or at least that Abrams couldn’t have been expected to write an entirely objective review of Cohen’s book. Abrams is the Program Chair for the Society’s upcoming 5th International Conference, sponsored by the American Cancer Society. He and Cohen will be sharing the stage for the “Intro/Welcome.” Does it matter that most NEJM readers wouldn’t have learned of this association by reading the review? Probably not, in the case of readers who are well-versed in the misleading language of “CAM.”

I believe that most readers of medical journals are not so sophisticated. Otherwise, how could it have been so easy for “CAM” literature to seep through the usual evaluative filters, not only in medical schools and government but in the editorial boardrooms of prestigious journals? For anyone from the Journal who might be following this thread, Dr. Sampson’s satirical but deadly serious account of “how we did it” is obligatory reading.

Do “Integrative Oncology” Methods have Value?

Now let’s take a look at what Dr. Cohen’s book and the SIO are up to. The book’s introduction and table of contents are available on Amazon.com. The introduction contains the usual, misleading assertions and falsehoods that are ubiquitous in “CAM” promotions. I’ve added a few hyperlinks:

Touched by a Touched Healing Toucher

Recent posts by Drs. Sampson and Hansen and some recent comments have got me to thinking for the umpteenth time about this issue: quackery is quackery, even if it seems harmless and even if some people seek it. This is the first of a series that will discuss it. I’m afraid I will ramble a bit; it may be that not every post will support that premise. Nevertheless, in the aggregate I’ll try to do exactly that.

The posts about Healing Touch sent me on a walk down memory lane, to one of my early forays into “CAM” skepticism. It was there that I discovered just how removed from reality some true believers, even those that project a superficial air of sobriety, can be. Here I’ll recount a brief exchange that I had with one such person, who was undoubtedly well-meaning. My attempts to influence her by the use of reason proved futile.

Shortly after the publication of the famous Emily Rosa article in 1998, I read a report about it in Newsday. It wasn’t all that bad, but my annoyance with mainstream publications giving the slightest credence to “alternative medicine” had been growing, and this moved me to act. I wrote a diatribe to Newsday that was not published (I can’t imagine why):

To the Editor:

“Therapeutic touch” is such obvious humbug that it never should have been taken seriously by anyone with the slightest aquaintance with how things work. Nevertheless, academic careers have been based on it, hundreds of useless papers have been written about it, courses in it have been given and even required of nursing students, grant money has been provided for it (but not used to test it!), and scores of ridiculous magazine and newspaper articles have praised it, apparently to a naive and credulous public. All of this constitutes a huge embarrassment to nurses, a fact that would appear to be lost on their largest professional organization (the ANA).

One of the statements in your article about the JAMA study was incorrect: the practitioners were not able to detect the energy field half of the time. They were able to guess the correct hand half the time, as would be predicted by chance alone. Thus there is no evidence that the “energy field” was detected at all. This is no surprise, because this kind of “energy field” exists only in the fantasies of true believers.

Dolores Krieger’s objection to the study, that the right practitioners were not tested, is disingenuous. She has been asked numerous times, by James Randi and others, to submit to testing of the same sort as described in Rosa’s study (Randi’s foundation has even offered a $1 million reward for anyone who can demonstrate the ability to detect the “energy field”!). Neither she nor any of her trainees or colleagues has come forward, nor has any of them published a single study supporting the efficacy of “therapeutic touch.”

Among the shamelessly fawning, uncritical articles on TT referred to above is one in Newsday by Tina Morales, 7/8/96. Really, now. There are very simple, basic skills useful for evaluating questionable claims. If the writer doesn’t have them the editor certainly should!

Before gentle readers admonish me for the scolding, schoolmarmish tone of that letter, let me assure them that I have long since learned to couch my objections to “woo” in more matter-of-fact, less provocative language. As frustrating as it may be, amiable, well-meaning, intelligent people who haven’t the slightest idea how to evaluate questionable claims vastly outnumber their more savvy counterparts, even in surprising fields: journalism and medicine, for example. Ten years ago I had no intention of becoming more than a temporary, annoying gadfly. I imagined that the “CAM” fad would soon blow over, and that I’d go back to spending my free time watching re-runs of Seinfeld and Law and Order. Alas, ’twas not to be. Patience.
