Seven years ago, I returned to Michigan, where I was born and spent the first quarter century of my life, after an absence of more than 20 years. In the interim, I had done my surgical residency and earned my PhD in Cleveland, a surgical oncology fellowship in Chicago, and worked in New Jersey at my first academic job for eight and a half years. Then I found a job back in Detroit and was lured back. One of the odd things about this return after such a long absence was the culture shock, how much I had forgotten about the Detroit area. One of those things that I had forgotten is just how crazy about hockey Michigan, in particular Detroit (meaning the Detroit metropolitan area), is. Detroiters love their Red Wings—love them. Hockey is ingrained in the suburban culture from a very young age, so much so that many Canadians would feel right at home here. Memories of trying and failing to be halfway decent at street hockey and of not being anywhere good enough a skater even to try real hockey as a teen came flooding back to me. (It didn’t help that back then I was approaching six feet tall and weighed only 135 lbs.; “beanpole” didn’t even begin to describe me back then.) In fact, the “cultural center” of the town where I live consists of—I kid you not—a hockey rink and some classrooms that are used for various community functions. No, really, it’s named the city’s Cultural Center.
So it should be no surprise, given how much Detroiters love hockey in general and their Red Wings in particular that it was big news here in late October when Red Wing legend Gordie Howe at age 86 suffered a debilitating stroke that paralyzed the right side of his body, a condition known as hemiplegia. Understandably, there was an outpouring of good wishes for recovery, coupled with retrospectives of Howe’s stellar hockey career. Indeed, I remember that it sounded bad enough from the tenor of the news reports at the time that it seemed likely that Howe would not survive. But survive he did, and is apparently recovering slowly, with occasional setbacks, such as a recent hospitalization in early December for a suspected “mini-stroke” that turned out to be dehydration and several such smaller strokes before that. The most recent press report I saw before the announcements I’m going to discuss described Howe as on the upswing again.
Then, on Friday, I saw headlines all over the place that were basically similar to this Detroit Free Press headline: Gordie Howe underwent stem cell clinical trial in Mexico. The story consisted largely of a press release from Howe’s family that read:
In the fascinating, if not rational, world of so-called complementary and alternative medicine, the age of the patient rarely seems to matter. This stands in stark contrast to the practice of science-based medicine. Sure, there is some physiological overlap across the spectrum of age, but caring for children often requires a vastly-different approach and there are numerous conditions not seen or only seen in kids.
Alternative medicine is more about the underlying belief system rather than the actual physiology, however. Chiropractic is chiropractic whether the subluxation belongs to a neonate or a nonagenarian. In traditional Chinese medicine, the flow of chi is obstructed in youngsters and old fogeys alike. No matter the length of our telomeres in fact, every major form of alternative medicine appears to contain a subset of practitioners that claim unique expertise in maximizing health and wellbeing at any age. But for kids, they simply do the same thing they would do for an older patient.
Newborns appear to be an increasingly-popular target of irregular medical practitioners. Even the unborn baby still in their mother’s womb isn’t safe. A generous interpretation would be that these true believers simply wish to aid in establishing health early in a child’s life, while the cynic in me worries that establishing a lifetime of billing opportunities might be the primary motivating factor.

Today’s post isn’t about the flu vaccine, but that vaccine played a part in bringing you today’s topic. It seems that this year’s vaccine is a mediocre match for the circulating strains of influenza, and I was one of the unlucky ones in whom it didn’t appear to provide much protection. After spending several days effectively bedridden, I still feel like I’m emerging from a cognitive fog. So today’s post will be short. In the midst of my own infection, the results of a new study were announced that examined the effects of HPV vaccination on indicators of sexual behaviour in adolescent girls. I admit to being a bit dumbfounded by the topic when I heard it, and I initially thought I had heard the research question incorrectly. After all, the answer seemed (to me) so clearly self-evident, I questioned if this was an ineffective use of research dollars. This question seemed as pertinent as continuing to study the relationship between vaccines and autism: there is little reason to think there would be any causal relationship. But surveys of parents show this is a real concern for some. And now we have an answer grounded in real-world evidence. (more…)
Pictured: Test subjects probably not worth a press release.
A recent study addresses the problem of sensationalism in the communication of science news, an issue we deal with on a regular basis. The study was titled “The association between exaggeration in health related science news and academic press releases: retrospective observational study“. The results show two interesting things – that university press releases frequently overhype the results of studies, and that this has a dramatic effect on overall reporting about the research.
The authors reviewed “Press releases (n=462) on biomedical and health related science issued by 20 leading UK universities in 2011, alongside their associated peer reviewed research papers and news stories (n=668).” They found that 40% of the press releases contained exaggerated health advice, 33% overemphasized the causal connection, and 36% exaggerated the ability to extrapolate animal and cell data to humans.”
When press releases contained such exaggeration, 58%, 81%, and 86% of news stories, respectively, contained similar exaggeration, compared with exaggeration rates of 17%, 18%, and 10% in news when the press releases were not exaggerated.
This study points a finger directly at academic press offices as a significant source of bad science news reporting. This does not let other links in the news chain off the hook, however. (more…)
A recent study in the Journal of General Internal Medicine evaluated a treatment for constipation. It tested whether training patients to massage the perineum (the area between the vagina or scrotum and the anus) would improve their reported bowel function and quality of life at 4 weeks after training. They found that it did. It’s a simple, innocuous treatment that may be worth trying, but why, oh why, did they have to call it “acupressure”? That irritated me. Should it have? Why should it matter? Isn’t a rose by any other name still a rose? Is this a meaningless semantic quibble and hypersensitivity on my part, or am I right to see it as yet another example of quackademia’s attempts to infiltrate science-based medicine? I’ll explain my thinking and let you decide for yourself. (more…)
I have yet another grant deadline to deal with, this time for the Department of Defense Congressionally Directed Medical Research Programs, this time around its Breast Cancer Research Program. Unfortunately, that put a high degree of time pressure on me. Fortunately, there’s still stuff in the archives of my not-so-secret other blog that I deem quite appropriate for this blog and that can be updated with minimal effort. If you don’t know what I’m talking about when I refer to my not-so-secret other blog, then it’ll definitely be new to you. If you haven’t been reading that blog for at least four and a half years, it’ll be new to you as well. And even if you have seen it before, I think it’s worth revisiting.
Why? It came up because of an encounter I had on Twitter with Jane Orient, MD, who, as you might recall, is the executive director of the American Association of Physicians and Surgeons (AAPS). I’ve written about the AAPS before. You can get the details in the link, but if you don’t have time suffice to say that it is an entire organization of libertarian-leaning “brave maverick doctors” who think Medicare is unconstitutional, don’t believe that the government should have much, if anything, to do with regulating the practice of medicine, and reject evidence-based guidelines as an unholy affront to the independence of the physician. Along the way, the AAPS, through its journal, The Journal of American Association of Physicians and Surgeons (often abbreviated JPANDS), promoted antivaccine views, including the discredited concept that vaccines cause sudden infant death syndrome, HIV/AIDS denialism, and the scientifically unsupported idea that abortion causes breast cancer (a topic I might have to revisit, given the activity promoting it recently).
In any case, two or three weeks ago, I was having a bit of an exchange with Dr. Orient over anthropogenic global climate change (often abbreviated as AGW, for anthropogenic global warming, for short), the well-accepted science that concludes that CO2 generated by human activity is having a serious warming effect on the earth’s climate. As you might expect, she’s not big on this particular scientific consensus. I forgot about it, but then the other day saw this Tweet exchange between Dr. Orient and Ed Wiebe:
What you’ve just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.

Pictured: Toxins coming out. Or cancer. Whatever it is, it’s your fault.
My first experience with SCAM was as a first year medical student. I was on the bus to school when the person next to me asked, after looking at my reading material, if I was a medical student. Yes, I am. Why so was he, enrolled at the local naturopathic school. I knew nothing about naturopathy, or medicine for that matter, at the time, so when he told me that warts were not caused by a virus but in fact due to the body walling off toxins and expelling them through the skin, I did not have much to say. I suspected it was nuts, but lacked the education or understanding of disease to know for sure, and who knew, maybe he was on to something.
When we got to cutaneous diseases I learned that warts were indeed caused by the papilloma virus, not toxins, and the best therapy remained swinging a dead cat in a graveyard at midnight. So I filed that curious incident away as a fluke, even though it is part of standard naturopathic teaching, which is often separated from reality.
It should not have surprised me that there is a whole field of pseudo-medicine devoted to the pseudo-treatment of pseudo-toxins that goes by the nom de scam of Homotoxicology. Yet another One True Cause of all disease. Being a splitter, I think Harriet missed this one. All diseases in this particular SCAM are due the toxins and the bodies attempt to remove them. (more…)
The Maryland Naturopathic Doctors Association is not pleased with the Society for Science-Based Medicine. Not at all.
That is a good thing, for several reasons. It demonstrates the importance of stopping naturopathic licensing (and practice expansion) legislation in the state legislatures. It shows how they handle legitimate criticism of their practices. And it is a lesson in their modus operandi of obfuscating the facts with platitudinous- but-vague pronouncements about their education, training and practice, pronouncements that wither under criticism.
Why is the MNDA so upset with the SFSBM?
We’ll answer that question soon, but some background first. The Maryland Legislature passed a naturopathic licensing bill this year. Fortunately, as I’ve written, the Legislature didn’t give naturopaths everything they wanted, such as the right to prescribe real drugs. That’s not stopping them from coming back to the Legislature to revisit the issue. According to naturopathic school Bastyr’s website:
The [Maryland] law limits some parts of the naturopathic scope of practice — such as intravenous (IV) therapies and prescription drugs — that the state association will work to secure in the future.
Instead of giving naturopaths their own regulatory board, like they wanted, the Legislature put them under the authority of the Maryland Board of Physicians. The Legislature created a Naturopathic Advisory Committee to recommend regulations governing naturopathic practice to the Board. The Maryland Naturopathic Doctors Association (MNDA) states, incorrectly, on its website that the Committee will actually be promulgating the regulations and implementing the law. The statute is quite clear that this is not the case. Those duties are entirely within the jurisdiction of the Board. (more…)
“What’s the harm?” is an insidious idea when used as a justification for unscientific medical treatments. The argument is typically put forward with the assumption that direct physical harm is the only type of harm that can result from such treatments, so as long as they aren’t toxic there is no downside to trying them. Harm comes in many forms, however: delayed effective treatment, wasted time and energy, financial harm, the psychological harm of false hope, and the downstream effects of instilling unscientific beliefs regarding health care.
One other form of harm is physical but is not due to direct physical damage or toxicity. Rather, it is caused by CAM treatments interacting with proven therapies. A recent survey, presented at the Clinical Oncology Society of Australia annual scientific meeting, explored the potential for such interactions among oncology patients. Lead researcher Sally Brooks found that, in addition to vitamins and minerals, cancer patients were most interested in fish oil, turmeric, coenzyme Q10, milk thistle, green tea, ginger, lactobacillus, licorice, Astragalus and reishi mushrooms.
As I have written many times before, herbs are drugs, but many patients do not treat them as such because they are regulated and marketed as “supplements,” more like food than drugs. There are concerns that many vitamin and herbal products may interact with chemotherapy or radiation therapy in order to reduce effectiveness or even increase side effects. (more…)
3D model of dichlorodiphenyltrichloroethane (DDT), an insecticide
I think everyone would agree that it would not be a good idea to put pesticides in a saltshaker and add them to our food at the table. But there is little agreement when it comes to their use in agriculture. How much gets into our food? What are the effects on our health? On the environment? Is there a safer alternative?
Where should we look to find science-based answers to those questions? One place we should not look is books written by biased non-scientists to advance their personal agendas. A friend recently sent me a prime example of such a book: Myths of Safe Pesticides, by André Leu, an organic farmer whose opinions preceded his research and whose bias is revealed in the very title.
