Several of us have written about how contemporary quacks have artfully pitched their wares to a higherbrow market than their predecessors were accustomed to, back in the day. Through clever packaging,* quacks today can reasonably hope to become professors at prestigious medical schools, to control and receive substantial grant money from the NIH, to preside over reviews for the Cochrane Collaboration, to be featured as guests and even as hosts on mainstream television networks and on PBS, to issue opinions in the name of the National Academy of Sciences, to be patronized by powerful politicians, and even to be chosen by U.S. presidents to chair influential government commissions.
The most successful pitch so far, and the one that the fattest quack-cats of all have apparently decided to bet the farm on, is “integrative medicine” (IM). Good call: the term avoids any direct mention of the only thing that distinguishes it from plain medicine. Its proponents, unsurprisingly, have increasingly come to understand that when they are asked to explain what IM is, it is prudent to leave some things to the imagination. They’re more likely to get a warm reception if they lead people to believe that IM has to do with reaching goals that almost everyone agrees are worthy: compassionate, affordable health care for all, for example.
In that vein, the two most consistent IM pitches in recent years—seen repeatedly in statements found in links from this post—are that IM is “preventive medicine” and that it involves “patient-centered care.” I demolished the “preventive” claim a couple of years ago, as did Drs. Lipson, Gorski, and probably others. Today I’ll explain why the “patient-centered care” claim is worse than fatuous.
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…)

Online discussions on the merits of alternative medicine can get quite heated. And its proponents, given enough time, will inevitably cite the same drug as “evidence” of the failings of science. Call it Gavura’s Law, with apologies to Mike Godwin:
As an online discussion on the effectiveness of alternative medicine grows longer, the probability that thalidomide will be cited approaches one.
A recent comment on my own blog, regarding the homeopathic product Traumeel, is typical:
If the scientific method is all that separates an accepted claim, ie Thalidomide, Vioxx, Bextra, Darvon, from mere anecdote, of what benefit is the Science?
As a non-scientist consumer, I’ll take the anecdotes and my own experience. Thank you.
If scientists want to be taken seriously, they must stop selling themselves to the highest bidder becoming corporate whores without a shred of decency. To my mind, that’s how the claims for Thalidomide, Vioxx, Bextra, Darvon were accepted, making the scientific method utterly worthless.
To this commenter, “science has been wrong before.” And that invalidates science, and apparently validates homeopathy. It’s a fallacious argument. But does thalidomide actually represent a failing of science-based medicine? No, not even close. It’s so wrong, it’s not even wrong. Thalidomide is good example of the importance of science-based medicine and why allowing alternative medicine to be sold in the absence of good science is a concern. (more…)
I have as much of a sense of nostalgia as anyone. I love history. I think that there is lots to be said about the “good old days,” whenever the heck they were. I do not, however, think that the “good old days” generally include medicine.
The fact is that it’s only been about 100 or so years since medical practitioners really got their acts together and started to be able to figure out if they were actually doing anything good. Prior to that, medicine was a world of humo(u)rs and miasms, treated by bleeding, burning, and purging, plants and animal matter of all sorts (the 6th century Chinese apparently liked otter feces) and all sorts of other awfulness. In light of some of the things that were done, it’s kind of amazing that anyone survived their treatments. Mostly, people (and horses) survived in spite of the crazy things that were done to them.
Nevertheless, in those wild and wooly days of yesteryear, enterprising medical entrepreneurs turned out an endless stream of products, with some pretty fantastic claims. They designed some absolutely artistic advertising cards to go along with those claims, too. These trade cards surged onto the scene in the 1870′s, coinciding with the advent of color printing.
Mea culpa to the max. I completely forgot that today is my day to post on SBM, so I’m going to have to cheat a little. Here is a link to a recent article by yours truly that appeared on Virtual Mentor, an online ethics journal published by the AMA with major input from medical students. Note that I didn’t write the initial scenario; that was provided to me for my comments. The contents for the entire issue, titled “Complementary and Alternative Therapies—Medicine’s Response,” are here. Check out some of the other contributors (I was unaware of who they would be when I agreed to write my piece).
Editor’s note: This weekend was a big grant writing weekend for me. I’m resubmitting my R01, which means that between now and July 1 or so, my life is insanity, as I try to rewrite it into a form that has a fighting chance of being in the top 7%, which is about the level the NCI is funding at right now. This weekend, I buried myself in my Sanctum Sanctorum and tried like heck to try to pound the revision into a really good draft that I can distribute to my colleagues for feedback. Fortunately, I have some old posts that I can pull out, tart up (i.e., update a bit, as in correcting the parts that led me to groan as I reread them, thereby hopefully making them better). I think they’re quite good, if I do say so myself; so hopefully you will too.
There are some arguments made in blogs, articles, or books that strike me so hard that I remember them, even three and a half years later. Sometimes I even file them away for later use or response if the issue raised by them is interesting, relevant or compelling enough to me. Although this topic is a bit broader than many of the topics I write about for this blog, I think it also goes to the heart of science-based medicine and communicating scientific skepticism about medicine to the masses. A few years back, a Swedish blogger named Martin Rundkvist made a rather provocative observation about skepticism. Specifically, he argued that a “real skeptic always sides with scientific consensus.” Among his reasons was this one:
Science presupposes that all participants have a skeptical frame of mind and arrive at conclusions through rational deliberation. If a large group of knowledgeable people working in this way arrive at a consensus opinion, then there is really no good reason for anybody with less knowledge of the subject to question it. Informed consensus is how scientific truth is established. It’s always provisional and open to reevaluation, but as long as there’s informed consensus, then that’s our best knowledge. Humanity’s best knowledge.
Although at the time I saw where Martin was coming from, I found this viewpoint somewhat disturbing, leading me to echo Martin’s own words in response to his own rhetorical question asking whether accepting a scientific consensus is nothing more than “kowtowing to white-coated authority”: Well, yes and no.
A good case of smallpox may rid the system of more scrofulous, tubercular, syphilitic and other poisons than could otherwise be eliminated in a lifetime. Therefore, smallpox is certainly to be preferred to vaccination. The one means elimination of chronic disease, the other the making of it.
Naturopaths do not believe in artificial immunization . . .
—Harry Riley Spitler, Basic Naturopathy: a textbook (American Naturopathic Association, Inc., 1948). Quoted here.
Here’s what a good case of smallpox will do for you:
If you’re lucky enough to beat the reaper (20-60%; 80% or higher in infants) or blindness (up to 30%), those blisters will leave you scarred for life. Oh, and the next time a good smallpox epidemic comes around, your children born since the last one will catch it and contribute their fair share to the death rate. But not you because you’ll be immune, so you’ll have the “preferred” experience of watching your children die well before you do.
Steven Salzberg, a friend of this blog and Director of the Center for Bioinformatics and Computational Biology at the University of Maryland, is on the editorial boards of three of the many journals published by BioMed Central (BMC), an important source of open-access, peer-reviewed biomedical reports. He is disturbed by the presence of two other journals under the BMC umbrella: Chinese Medicine and BMC Complementary and Alternative Medicine. A couple of days ago, on his Forbes science blog, Dr. Salzberg explained why. Here are some excerpts:
The Chinese Medicine journal promotes, according to its own mission statement, studies of “acupuncture, Tui-na, Qi-qong, Tai Chi Quan, energy research,” and other nonsense. Tui na, for example, supposedly “affects the flow of energy by holding and pressing the body at acupressure points.”
Right. What is this doing in a scientific journal?… I support BMC…But their corporate leaders seem to care more about expanding their stable than about maintaining the integrity of science. Chinese Medicine simply does not belong in the company of respectable scientific journals.
Forming a scientific journal whose goal is to validate antiquated, unproven superstitions is simply not science, whatever the editors of Chinese Medicine claim.
BMC should be embarrassed to be publishing journals that promote anti-scientific theories and otherwise muddy the literature. By supporting these journals, they undermine the credibility of many excellent BMC journals. They should cut these journals loose.
What does honey bee colony collapse disorder have to do with a potential new cancer treatment?
They both relate – in a convoluted manner – to an old antibacterial drug called nitroxoline.
True to my devotion as a natural product pharmacologist, I’m proud to say that new life would not have come to nitroxoline had not a fungal natural product called fumagillin been studied as an antiangiogenic anticancer drug – one that inhibits the formation of new blood vessels.
One of our readers suggested that I review the book The Great Influenza: The Epic Story of the Deadliest Plague in History, by John M. Barry. It’s not a new book (it was published in 2004) but it is very pertinent to several of the issues that we have been discussing on this blog, especially in regards to the current anti-vaccine movement. It’s well worth reading for its historical insights, for its illumination of the scientific method, and for its accurate reporting of what science has learned about influenza.
In the great flu epidemic of 1918, influenza killed as many people in 24 weeks as AIDS has killed in 24 years. It’s hard to even imagine what that must have been like, but this book helps us imagine it. It tells horror stories: children found alone and starving beside the corpses of their parents in homes where all the adults had died, decomposing bodies piling up because there was no one left who was healthy enough to bury them. Sometimes the disease developed with stunning rapidity: during one 3 mile streetcar trip, the conductor, 3 passengers, and the driver died. In another incident, apparently healthy soldiers were being transferred to a new post by train; during the trip, men started coughing, bleeding, and collapsing; and by the time it arrived at its destination, 25% of the soldiers were so sick they had to be taken directly from train to hospital. 2/3 of them were eventually hospitalized in all, and 10% of them died. The mind boggles. (more…)
