The Wall Street Journal has an assessment of probiotics in the Jan 13, 2009 issue entitled “Bug Crazy: Assessing the Benefits of Probiotics.” For some reason when I wander around the hospital on rounds people show me articles such as this and ask, so whatcha think about this? Probiotics are interesting. They are live bacteria given to treat and prevent diseases. It is one of those overlap areas for scientific medicine and so called alternative medicine. There are good clinical trials to suggest areas where these agents are of benefit, but other aspects of their use are blown out of proportion for the real or imagined benefit probiotics may provide. Much of alternative medicine where it overlaps with real medicine is the art of making therapeutic mountains out of clinical molehills. The Wall Street Journal article is the kind of reporting that drives. Me. Nuts. It drives me nuts because the reporting acts as if the underlying assumptions of the therapies are true. (more…)
I recently watched a special news report about John McCain leading the charge towards making legislative earmarks illegal. The Economist defines earmarks this way:
Earmarks, for the uninitiated, are spending projects that are directly requested by individual members of Congress and are not subject to competitive bidding.
Most Americans are rightly upset about the practice of slipping pet projects into larger, well-vetted, and consensus-built legislative initiatives. They know instinctively that it’s morally wrong to sneak in personal favors and appropriate tax payer dollars to special interest groups without allowing others to weigh in. I certainly hope that McCain and his peers will succeed in discontinuing this corrupt practice.
Coincidentally, just after I watched this news report about earmarks, I went online to catch up on my blog reading. The first post I encountered made reference to an opinion piece written by Deepak Chopra, Andrew Weil, Dean Ornish, and Rustum Roy in the Wall Street Journal. Chopra et al. were asking Americans to redouble their efforts to adopt healthy lifestyles (including wholesome diets and regular physical activity) as a means to promote good health and avoid disease. At the end of the article they slipped in a plea for President-elect Obama to consider integrating alternative medicine practices (which included everything from healthy diet to meditation and acupuncture) into a government-sponsored approach to health.
It is without controversy that the number of autism diagnoses being made is on the rise. In 1991 there were about 6 cases per 10,000 births, and in 2001 there were about 42. This number continues to rise at about the same rate.
The cause of this rise, however, is very controversial. There are basically two schools of thought: 1 – that true autism rates are on the rise, and 2 – that the measured rise is an artifact of increased surveillance and a broadening of the definition. I wrote previously about this very controversy, in which I concluded that the expanded diagnosis hypothesis is much better supported by the evidence.
Now, a new study published last week in the journal Epidemiology is being presented by proponents of the epidemic hypothesis as support for their view. A closer look, however, reveals that this study does not support the epidemic hypothesis and adds little to the overall literature on this question.
The quest of advocates of unscientific medicine, the so-called “complementary and alternative medicine” (CAM) movement is to convince policy makers, patients, and physicians that it does not deserve the rubric of “alternative,” that it is in fact mainstream. Indeed, that is the very reason why “alternative” medicine morphed into CAM in order to soften the “alternative” label. Increasingly, however, advocates of such highly implausible medical practices appear no longer to like CAM as term for their dubious practicies, because it still uses the word “alternative.” That is, of course, because they recognize that labeling something as “alternative” in relationship to scientific medicine automatically implies inferiority, and CAM advocates are nothing if not full of hubris. Such a term conflicts with their desire to “go mainstream,” and they most definitely do want to go mainstream, but they want to do it on their own terms, without all that pesky mucking about with science, evidence, and rigorous clinical trials. Consequently, they increasingly use a new term, a shiny term, a term free of that pesky “alternative” label. Now they want to “integrate” their unscientific placebo-based practice with real, scientific medicine. Thus was born the term “integrative” medicine (IM, an abbreviation that is the same as that for internal medicine, an identity that I don’t consider coincidence).
One of the biggest complaints we at SBM (or at least I at SBM) have about the attitude of practitioners of scientific medicine towards CAM/IM is that most of them do not see it as a major problem. Dr. Jones characterized this attitude as the “shruggie” attitude, and it’s a perfect term. Equally perfect is her analogy as to why “integrating” pseudoscience with medical science is not a good idea. I myself have lamented the infiltration of pseudoscience and outright quackery into medical academia and the role that the National Center for Complementary and Alternative Medicine (NCCAM) has played in promoting that infiltration. In addition, wealthy patrons of CAM/IM such as Donna Karan and the Bravewell Collaborative have been generous spreading their money around. In this increasingly cash-strapped health care environment, hospitals know on which side their bread is buttered and see the “integration” of woo into their service portfolio as a means of beefing up the bottom line with cash on the barrelhead transactions that require no mucking about with nasty insurance forms. In fact, services such as reiki, homeopathy, acupuncture, and others often require no forms other than credit card receipts for the patient to sign.
Without question, vaccination has been one of the most important interventions in disease prevention that has ever been developed. In spite of the demonstrable, and ongoing, success of vaccination, a small, but vocal, anti-vaccination movement has developed in human medicine, occasionally buttressed by horrifying instances of adverse reactions, as well as the occasional publications in scientific journals (vis, the Wakefield debacle). Vaccine development continues, and human health continues to benefit, as new vaccines are developed and tested prior to release.
In veterinary medicine, vaccination has also proven to be a boon for animal health. Diseases such as canine parvovirus and canine distemper, feline leukemia, or equine tetanus, have been greatly reduced – in some cases, nearly eliminated – by vaccination. And, as in human medicine, a small, but vocal, anti-vaccination movement has developed, regaling fearful listeners with tales of acute harm, or chronic, low-grade disease (sometimes termed “vaccinosis”).
Can y’believe it? The W^5/2™, that cesspool of Afflicted Sophistry and Festering Fallacy—not to say that wellspring of Awesome and Absolutely Annoying (Cloying) Alliteration© and that Mother of all Maddening Mixed Metaphors and Sundry Similitudes®—is back! Yup, like the proverbial phoenix rising from the ashes of near-terminal procrastination, and due to overwhelming popular demand, the W^5/2 is reborn!!! Well, it also might have something to do with yer faithful servant needing some time to put together a real paper or two…naaahh! But what the hay, let’s just dive right in and pretend that nothin’s changed, shall we?
When we were forming the National Council against Health Fraud I wondered aloud to the president, Bill Jarvis, what we would do if society solved the chiropractic problem. Bill laughed and said there would never be an end to quackery claims.
How right he was. But why? Many express surprise that at this time of remarkable intellectual and scientific advance, so many people choose to believe in irrational medical claims. The answer I am used to is the one that explains the difference between the attraction of subjective versus the dryness of the objective; between reflex and conditioned responses and rational thought, and between immediate emotionally gratifying, low-level mid-brain reactions and slow-reacting, cool, higher level intellectual thought. These comparisons are all valid but in trying to answer the question, we can miss the constancy of human nature biology, the dimension of time flow, the changing nature of evidence, and as yet unemphasized, the changes and evolution of measurement.…
Before Evidence Based Medicine (EBM) was devised, and the randomized clinical trial (RCT) accepted as the so-called gold standard, our evidential decisions turned on balances or ratios of science/nonsense, rationality/irrationality, reality/delusion, and an estimate of plausibility/implausibility. We can see now that the concept of EBM introduced a new set of standards to our equations balances – proof by RCT and their derivatives, systematic reviews (SRs). The demand for proof by RCT and and SR relegated the previous standards, the unbalanced ratio concept, to the level of anecdote and “uncontrolled observation.” We had to start over again with a new standard.
President-elect Obama’s nomination of CNN medical correspondent, Sanjay Gupta, for the Office of Surgeon General of the United States has ignited a firestorm of debate across the Internet. Some argue that he is not qualified for the position, others say that his charisma would be a boon to public health communications, though the lay majority appear to have mixed feelings.
It is highly irregular for a Surgeon General nominee to be announced before the Secretary of Health and Human Services is confirmed. This faux pas in itself may speak to an irresistible opportunity for self-promotion, or that the Senate confirmation hearing is not the independent review event that we assume it is.
At age 39, Gupta has long aspired to become the Surgeon General, as sources close to him report that he has been saying (since age 33) that “it’s the next logical step in his career development.”
But before we draw conclusions about who’s right for the job, we need to understand what the job entails.
I asked Dr. Richard Carmona, 17th Surgeon General of the United States, to explain the roles and responsibilities of the office. A summary of our conversation follows:
Dr. Robert Sears, son of the perhaps more famous Dr. William Sears (both pediatricians), has continued his father’s work of publishing popular books for parents. He wrote The Vaccine Book: Making the right decision for your child, published in October 2007. In it he advocates his Dr. Bob’s Alternative Vaccine Schedule. Much of his claims made in the book are repeated on his Ask Dr. Sears website.
In the latest issue of Pediatrics, Paul Offit, along with Charlotte Moser, write a detailed analysis of Dr. Bob’s alternative vaccine schedule, systematically reviewing Dr. Sears’ claims. It is essential reading for anyone interested in the popular vaccine controversy. Paul Offit also recently published his own book, Autism’s False Prophets, in which he goes into great detail about the history and science behind the claims by anti-vaccination advocates of the risks of vaccines, most famously the claim that vaccines are linked to autism.
Dr. Sears does not come off as a hard core anti-vaccinationist. I am still trying to figure out his perspective from reading his articles. It seems as if he is trying to be popular by straddling the fence, and offering what he thinks might be a reasonable compromise. For example, he writes on his site:
The bottom line is that more and more parents want options. If we don’t provide them with options they are comfortable with, more parents will opt out of vaccines altogether. We will then see more and more disease fatalities and complications.
Unfortunately, this is like trying to compromise between mutually exclusive positions, like young-earth creationism and evolution. It doesn’t work. Dr. Sears is left giving his readers, who will likely be comprised of many parents trying to decide whether or not to vaccinate their children, with partial information or misinformation. Offit and Moser do a great job of exposing this deception through misinformation.
