Typical example of a Vitamin K supplement.
Science is complicated. Simple concepts that appear at first to be obviously true or untrue usually turn out to be more nuanced than we thought. Newtonian physics was taken as “the truth” until we learned in the 20th century that it didn’t apply on cosmological or subatomic scales. Medicine and human physiology are more complicated than most people realize or want to believe. A case in point is the recent realization that vitamin K is not a single chemical compound, but a whole family of them, and that vitamin K2 has unique properties that vitamin K1 lacks.
Recently, there has been some interesting preclinical research on K2 that warrants further study to tease out its implications for human health, diet, and supplementation. There has also been a lot of hype that warrants taking its claims not with a grain but with a large bolus of salt. According to Canadian naturopath Kate Rhéaume-Bleue, author of Vitamin K2 and the Calcium Paradox:
- It could save your life
- It is missing from the modern diet
- It is the most important anti-aging nutrient for fighting wrinkles, Alzheimer’s, heart disease, osteoporosis and more
- It promotes straight, cavity-free teeth
- It is needed to get the benefits from calcium and vitamin D supplements; without it, those nutrients will increase the risk of heart attack and stroke
- It is the only vitamin known to prevent and reverse atherosclerosis
The old adage is still true: if something sounds too good to be true, it probably is. There is only weak evidence behind these strong claims. (more…)
Quackery has been steadily infiltrating academic medicine for at least two decades now in the form of what was once called “complementary and alternative medicine” but is now more commonly referred to as “integrative medicine.” Of course, as I’ve written many times before, what “integrative medicine” really means is the “integration” of quackery with science- and evidence-based medicine, to the detriment of SBM. As my good bud Mark Crislip once put it, “integrating” cow pie with apple pie does not improve the apple pie. Yet that is what’s going on in medical academia these days—with a vengeance. It’s a phenomenon that I like to call quackademic medicine, something that’s fast turning medical academia into medical quackademia. It is not, as its proponents claim, the “best of both worlds.”
In fact, it was my two recent publications bemoaning the infiltration of quackademic medicine into medical academia, one in Nature Reviews Cancer and one with Steve Novella in Trends in Molecular Medicine, that got me thinking again about this phenomenon. Actually, it was more my learning of yet another step deeper into quackademia by a once well-respected academic medical institution, occurring so soon after having just published two articles bemoaning that very tendency, that served as a harsh reminder of just what we’re up against. So I decided to greatly expand a post that I did for my not-so-super-secret other blog recently beyond a focus on just one institution, in order to try to demonstrate for you a bit more how and why quackery has found a comfortable place in medical academia and how, just when I thought things can’t get worse, they do. There is also room for hope in that I also found evidence that our criticisms are at least starting to be noticed. I begin with the sad tale of the Cleveland Clinic Foundation, which has gone one step beyond its previous embrace of traditional Chinese medicine. I’ll then discuss another unfortunate example, after which I’ll look a bit at the pushback and marketing of “integrative” medicine.
Foolproof cure for hiccups?
nOne of the most common questions I get in the newborn nursery, especially from first time parents, involves hiccups. Babies hiccup in the womb and most, if not all of them, will have periodic bouts of hiccups in the neonatal period. But many new parents are surprised by their baby’s first spasmodic contractions of the diaphragm. When brought up, it is often to simply acknowledge that their baby had a run of a few hiccups, usually associated with a feed, with some parents expressing surprise and others nervousness. Regardless of their assumed motivation, I always provide reassurance that hiccups are a normal experience for babies, as they are across the entire spectrum of age.
The medical term for hiccups, which I admit I only learned while researching this topic, is “singultus.” We doctors like to use our own peculiar language as much as possible in order to maintain a sense of superiority when dealing with today’s internet savvy customers, I mean patients, and their families. The rumbling of your stomach, that’s actually borborygmus. You don’t have a unibrow above your nose, that’s a synophrys. It isn’t abdominal or pelvic discomfort associated with ovulation that keeps annoying you midway through your menstrual cycle, it’s mittelschmerz. But since this is a forum meant for general public consumption, I’ll use the rather pedestrian and philistine “hiccup” for the duration of the post. (more…)
The supplement industry wants you to buy their products, and they’re not above using a little parental guilt to make you into a customer. In the photo above, the promoter is my local pharmacy, where the large window display caught my eye:
Give your Child The Tools to SUCCEED in School!
Who doesn’t want their child to succeed? And if you knew a supplement could give you or your child a learning edge, would you consider it? I’d imagine many do. Supplements have a remarkable health halo. As a pharmacist myself, I’ve noticed this when speaking with patients – few consumers identify any potential risk or downsides to supplement use. Some don’t even think of them as medicine at all. The marketing has resonated: Supplements are perceived as “safe”, “natural” and “effective”. But whether you’re giving your child a prescription medicine to treat attention deficit hyperactivity disorder, or you’re giving a supplement to “improve focus and brain function”, you’re still administering a chemical substance to a child with the intent of changing brain function. We’d probably think twice before pouring an unknown substance in our car’s gas tank, especially one claimed to boost performance. We’d probably ask for some evidence that it works, and some assurance it wouldn’t harm our vehicle. A decision to use a drug or supplement in a child deserves just as much consideration of benefits and risks. (more…)
It looks like we can file this one under “here we go again.” A small town in Colombia, El Carmen de Bolivar, has seen more than 200 girls hospitalized with a mysterious illness since May of this year. The symptoms include dizziness, headaches, and fainting. So far, all of the girls hospitalized have been found to be healthy and were quickly released from the hospital without discovering any specific disease or pathology.
Unfortunately I have to depend on news outlets to provide information about this case, and most are skimpy on details. However, taking what is being reported, the case has all the features of mass psychogenic illness. Specifically, the cases are clustering in a small community, which is typical for typical for episodes of mass delusions. The symptoms being reported are all subjective and the kinds of symptoms that can result entirely from psychological stress. I have seen no reports of objective clinical findings, such as fever, rash, abnormal laboratory findings, strange lesions, or objective findings on exam.
Doctors who have examined the patient feel that the presentation is consistent with psychogenic illness. I have discussed this at length previously. A psychogenic illness results from the physical manifestation of psychological stress. This is always partly a diagnosis of exclusion, meaning that other causes of the presenting symptoms need to be ruled out. However, it is more than just a diagnosis of exclusion, as there are sometimes clinical features that can be positively demonstrated to be psychological rather than physical. The ultimate test of the psychogenic diagnosis is that patients should improve with support and encouragement.
The bad news: in a disturbing attempt to woo customers, some Australian pharmacists are offering in-store consultations with naturopaths. The good news: Australian skeptics and supporters of science have had a lot of recent successes in combatting quackery.
Non-Doc in a Box
In an article in the Australian magazine The Skeptic, Loretta Marron reports on naturopaths in pharmacies. You can read it here. Pharmacy customers who want natural treatment alternatives are referred by pharmacy staff to an in-house naturopathy clinic. The cost, $90 for a one-hour consultation, is often covered by insurance. You can even get a Loyalty Card to make your fifth consultation free. They claim to “correct underlying causative factors,” advise about stress, diet, how to promote your vitality and immune system, etc. And they help you make informed decisions about your health (informed by their brand of misinformation).
They offer disproven diagnostic methods like iridology, live blood analysis, and bio-energetic screening with bogus machines that they claim can detect everything from vitamin deficiencies and parasites to “spinal energy” and “vaccination disturbance.” Marron doesn’t describe the treatments they recommend, but we can assume they are offering the usual naturopathic remedies, including homeopathy, in lieu of the pharmaceuticals that are the reason for the pharmacy’s existence.

We at the Science-Based Medicine blog believe that all medicine, regardless of where it comes from, should be held to a single science-based standard with regards to efficacy, effectiveness, and safety. We tend to focus primarily on “complementary and alternative medicine” (CAM), now more commonly known as “integrative medicine,” because (1) we believe it to be undermining the scientific basis of medicine and allowing outright quackery (or, as I like to refer to it, quackademic medicine) to infiltrate medical academia, which is fast becoming medical quackademia and (2) because when it comes to the other threats to the scientific basis of medicine as it is practiced today, such as pharma influence and various medical dogmatism, there are a whole host of active critics better equipped and more energetic than we are who can do the job (usually) better. That is why, whenever I hear advocates of CAM/”integrative medicine” attack us for not spending enough time on various corruptions of clinical trial processes or the perfidy of big pharma, I tend to gently tell them in my characteristically diplomatic manner that that’s what I like to call the “Why don’t you blog about what I think is important and interesting instead of what you think is important and interesting?” criticism, then I refer them to our posts on John Ioannidis, overdiagnosis and overtreatment, the shortcomings of mammography, or any number of other posts we at SBM have done through the years pointing out where current medical practice falls short. Indeed, it never fails to amuse me to point out how angry an eminent radiologist became at me for my posts criticizing him for his misleading attacks on certain studies that question the value of screening mammography.
In particular, though, I like to point out a post I did on vertebroplasty as a treatment for vertebral compression fractures (VCFs) due to osteoporosis. Basically, I discussed then recent evidence showing how vertebroplasty for such fractures is, basically, placebo medicine, no better than acupuncture. Indeed, I likened the state of evidence regarding vertebroplasty to that of acupuncture, in which small, pilot studies appear to be positive, but then the follow-up rigorous randomized clinical trials fail to find a benefit greater than that of placebo. It turns out that a rather telling study regarding vertebroplasty was published earlier this year that I somehow missed that addresses a problem we have in “conventional” medicine.
One of our goals here at SBM is to do more than just blog about the issues of science and pseudoscience in medicine that are our raison d’être. We also want to publish our science-based critiques in the peer-reviewed medical literature. Our first crack at this was an article by Steve Novella and myself published last month in Trends In Molecular Medicine entitled “Clinical trials of integrative medicine: testing whether magic works?” Even better, thanks to a press release and how the editors made the article free to all, it garnered more social media attention than any article previously published in TMM, and the editor has informed me that it “shot straight to the top of TMM’s ‘Most read’ article list and I anticipate it staying there for quite some time.” For this, Steve and I thank you, our readers, and those of you who spread the news. We’re hoping that this success garners more offers to write review and commentary articles for the peer-reviewed literature about topics near and dear to us.
Now, I’m happy to announce another commentary in the peer-reviewed literature. It’s an article I wrote for Nature Reviews Cancer that just appeared online yesterday entitled “Integrative oncology: Really the best of both worlds?” I must say, I’m quite proud of this one, and it is a big deal, hopefully to more people than just me. If you look up the impact factor for NRC, you’ll see it’s around 35, which is between The Lancet and JAMA.
Pictured: Cutting-edge medicine
I remain flummoxed. How do physicians and health care systems, trained in all the sciences that lie at the heart of medicine, justify the use of pseudo-medical interventions with no basis in reality? Rationalization. Making excuses:
a defense mechanism in which controversial behaviors or feelings are justified and explained in a seemingly rational or logical manner to avoid the true explanation, and are made consciously tolerable – or even admirable and superior – by plausible means.
Rationalization of the ridiculous comes in many forms. It has been said that it is a mark of a first rate intelligence to able to hold two contradictory ideas in the mind at the same time and still retain the ability to function. Clever as it is, I suspect the opposite is true. (more…)
Medical school clinical training
A new law in Missouri will allow medical school graduates who have not completed a residency to practice in underserved areas. They will be able to call themselves “doctor” but will be licensed as “assistant physicians” with significant limitations on their practice. (The first link is to Senate Bill 716, the bill that was passed and signed by the governor. It covers several subjects, so you will need to skip to page 8 to find the portion we’re discussing.)
The Missouri State Medical Association supports the new law and helped draft the original bill. It is designed to address the state’s critical need for primary care physicians – 40% of Missouri’s population lives in underserved areas but only 25% of the state’s physicians practice there, according to a 2009 survey. Underserved areas have high poverty rates, high infant mortality, large senior populations and fewer primary care physicians per capita. (more…)
