One of the overriding themes of the Science Based Medicine blog is to use rigorous science when evaluating any health claim – be it medical, dental, dietary, fitness, or any other assertion put forth with the intention of improving one’s health. Once the scientific evidence is evaluated as to efficacy, there are other criteria which must be taken into consideration, such as ease of administration, costs, possible adverse effects, and so on. Benefits have to be carefully weighed against risks to properly determine any appropriate course of action. For example, if a new pill is developed which is significantly better at , say, managing hypertension than existing medications, but it kills 10% of patients taking it, it obviously would not be the drug of choice. Conversely, if a proposed treatment, say homeopathy, is touted as being 100% safe with no side effects, but has absolutely zero benefits, it too would not be a recommended treatment. It’s a complicated and often ambiguous algorithm, and is imperfect due to the impossibility of attempting to quantify non-quantifiable values and qualities. (more…)
If there’s one thing that unites all countries and cultures, it’s our love of caffeine. Whether it’s coffee, tea or other foods, caffeine is the most widely consumed drug in the world — more than alcohol, and more than tobacco: 90% of adults worldwide consume caffeine daily. At doses found in food and beverages, the effects are predictable and the side effects are slight. But natural or not, caffeine is a drug; isolate the pure substance, and the risks change. It would be difficult for most people to drink 16 cups of coffee in a row, but that’s the equivalent of just one teaspoon of caffeine powder. If that doesn’t hospitalize you, a tablespoon of the powder will probably kill you. Yet despite the risks, there are no restrictions on the sale of caffeine powder. You can buy a 1kg bag for $35, which provides the caffeine of about 5,000 cups of coffee. Caffeine powder is freely available to buy because regulators treat it differently – not because of its inherent properties, but because it’s “natural” and sold as a dietary supplement rather than a drug. This is a regulatory double-standard that harms consumers. It’s leaving a body count. And it needs to change: (more…)
When I lecture about the need for science-based medicine (SBM), I have to pause about half-way through my list of all the things wrong with the current practice of medical science, and I balance my discussion by emphasizing what I am not saying: I am not saying that medical science is completely broken. It is just really challenging, we need to raise the threshold for what we consider reliable higher than most people think, and there are some practical fixes we can do, some of which are already in the works.
It is easy, however, to “demonize” any person, institution, or philosophy by taking all the negative aspects that are inevitably present and wrapping them up in a frightening package, perhaps throwing in some conspiracy thinking or sensational alarmism.
Take, for example, a recent article by F. William Engdahl, “Shocking Report from Medical Insiders“. The headline alone warns you that you may be in for some sensationalism.
I got an e-mail with a link to a video featuring “Dr.” Leonard Coldwell, a naturopath who has been characterized on RationalWiki as a scammer and all-round mountebank. Here are just a few examples of his claims in that video:
- Every cancer can be cured in 2-16 weeks.
- The second you are alkaline, the cancer already stops. A pH of 7.36 is ideal; 7.5 is best during the healing phase. [We are all alkaline. Normal pH is 7.35-7.45.]
- IV vitamin C makes tumors disappear in a couple of days.
- Very often table salt is 1/3 glass, 1/3 sand, and 1/3 salt. The glass and sand scratch the lining of the arteries, they bleed, and cholesterol is deposited there to stop the bleeding.
- Patients in burn units get 20-25 hard-boiled eggs a day because only cholesterol can rebuild healthy cells; 87% of a cell is built on cholesterol.
- Medical doctors have the shortest lifespan: 56. [Actually they live longer than average.]
My correspondent recognized that this video was dangerous charlatanism that could lead to harm for vulnerable patients. He called it a “train wreck, with fantasy piled upon idiocy.” His question was about the best way to convince someone that it was insane. He said, “If you could rely on someone to follow and understand basic information about the relevant claims, it would be a gimme. But to the casual disinterested observer, who can interpret the whole video as ‘Well, he just wants people to eat right,’ pointing out the individual bits of lunacy just looks like so much negativity.”
He asked, “How do I best represent what’s happening to someone who is either a) emotionally invested in this and/or b) casually approving of it? … I just want to be patient, not shout anyone down, not make anyone defensive, and then win. Very surprised I don’t already know how. But I feel like I don’t. What is the psychologically sophisticated approach to this?” (more…)
There can be no doubt that, when it comes to medicine, The Atlantic has an enormous blind spot. Under the guise of being seemingly “skeptical,” the magazine has, over the last few years, published some truly atrocious articles about medicine. I first noticed this during the H1N1 pandemic, when The Atlantic published an article lionizing flu vaccine “skeptic” Tom Jefferson, who, unfortunately, happens to be head of the Vaccines Field at the Cochrane Collaboration, entitled “Does the Vaccine Matter?” It was so bad that Mark Crislip did a paragraph-by-paragraph fisking of the article, while Revere also explained just where the article went so very, very wrong. Over at a blog known to many here, the question was asked whether The Atlantic (among other things) matters. It didn’t take The Atlantic long to cement its lack of judgment over medical stories by publishing, for example, a misguided defense of chelation therapy, a rather poor article by Megan McArdle on the relationship between health insurance status and mortality, and an article in which John Ioannidis’ work was represented as meaning we can’t believe anything in science-based medicine. Topping it all off was the most notorious article of all, the most blatant apologetics for alternative medicine in general and quackademic medicine in particular that Steve Novella or I have seen in a long time. The article was even entitled “The Triumph of New Age Medicine.”
Now The Atlantic has published an article that is, in essence, The Triumph of New Age Medicine, Part Deux. In this case, the article is by Jennie Rothenberg Gritz, a senior editor at The Atlantic, and entitled “The Evolution of Alternative Medicine.” It is, in essence, pure propaganda for the paired phenomena of “integrative” medicine and quackademic medicine, without which integrative medicine would likely not exist. The central message? It’s the same central (and false) message that advocates of quackademic medicine have been promoting for at least 25 years: “Hey, this stuff isn’t quackery any more! We’re scientific, ma-an!” You can even tell that’s going to be the central message from the tag line under the title:
When it comes to treating pain and chronic disease, many doctors are turning to treatments like acupuncture and meditation—but using them as part of a larger, integrative approach to health.
I am off to Chicago for 5 days to wow the SMACC crowd with my ID/SBM acumen. I hope. Given that most of my multiple-personalities do not seem to be able to get any work done, I am forced to write a brief post this week, limited by the battery life on my MacBook Air. Whatever I get down on paper? pixels? RAM? before the battery dies as I fly over the Rockies will be the post. It is times like this I wish I had Gorskian typing skills.
SBM has discussed the many limitations of chiropractic: the low grades for entry into chiropractic school, the inadequate training, their reason d’être, subluxations and their adjustments being divorced from reality, the lack of efficacy of chiropractic for any process beyond low back pain (and even that is no better than safer interventions), the fondness of chiropractors for other useless pseudo-medicines, and their opposition to vaccines.
Hm. When I put it like that chiropractic does appear a little sketchy. But is chiropractic safe? It is a hands-on intervention, for a brief period of time applying the same force to the neck as about 40% of hanging from the neck until dead. So there is certainly the potential for chiropractic to cause harm. (more…)
The FDA recently announced it would send field staff out to collect samples of commercially-manufactured raw dog and cat food. The samples will be analyzed for Salmonella, Listeria monocytogenes and E. coli, all of which have been found in raw pet food, in the animals who eat it, in their feces, on their bodies after eating it, in the areas they inhabit, and on their owner’s bodies. Not surprisingly, this has led to both pet and human infection and illness. If the FDA finds pathogens, it could result in a recall, a press release and Reportable Food Registry Submission. The next day, the CDC joined the effort to curb illness caused by pathogens in raw pet food by posting information on safe handling.
Because of the risk to public health, and the lack of any proven benefit of raw pet food diets, the FDA does not recommend them.
However, we understand that some people prefer to feed these types of diets to their pets.
And why is that? For some of the same reasons humans follow absurd diet fads: the “lone genius” discovery, it’s “natural,” anecdotal evidence, appeal to antiquity, anti-corporate sentiment, and “holistic” practitioner recommendations.
One of the major themes of science-based medicine (unsurprisingly) is that medicine should be based on science. We consider ourselves specialists in a larger movement defending science in general from mysticism, superstition, and spiritualism. We are not against anyone’s personal belief, and are officially agnostic toward any faith (as is science itself), but will vigorously defend science from any intrusion into its proper realm.
The so-called alternative medicine movement (CAM) is largely an attempt to insert religious beliefs into the practice and profession of medicine. CAM is also an attempt to create a double standard or even eliminate the standard of care so that any nonsense can flourish and con-artists and charlatans can practice their craft freely without being hounded by pesky regulations designed to protect the public. These are both insidious aspects of CAM that need to be exposed and vigorously opposed.
A recent article by Dr. Michel Accad demonstrates how brazenly some are trying to insert faith healing and spiritualism back into medicine. He does so by couching his arguments in philosophy and marketing terms, but in the end he is essentially saying that doctors should practice his faith. He doesn’t really make any arguments for this position, but rather simply gives a history of progress in Western thought as if that is sufficient. (more…)
A chiropractor in Illinois named Jeff Winternheimer claims to have discovered an effective way to heal herniated discs by rehydrating them. He calls it Functional Disc Rehydration and he offers it through a network of four offices in the Chicago area called the Illinois Back Clinic. He has lots of testimonials and one sorry amateurish attempt at a scientific study that claimed to show 100% improvement; but there is no published evidence, no controlled observations, and no comparison of his methods with other methods.
Degenerative disc disease
Between the spinal vertebrae there are soft, jelly-like compressible discs that act as shock absorbers. They are “corralled” by a fibrous annulus. As we get older, the disc material loses water and becomes less flexible; the disc thins, and the space between the vertebrae narrows, so in old age we are not quite as tall as we once were. Cracks in the annulus develop with age or with trauma, allowing the disc material to bulge out or rupture. Herniated discs don’t necessarily cause pain; disc degeneration can be seen on MRI in 37% of asymptomatic people over the age of 60.
A week ago, I attended the Center For Inquiry Reason for Change Conference, where I participated in a panel on—what else?—alternative medicine with—who else?—Harriet Hall and our fearless leader Steve Novella. Before the panel, we all gave brief talks on areas that we consider important. As you might expect, I chose to give a brief introduction to what I like to call “quackademic medicine,” defined as the pseudoscientific medicine being practiced and studied in academic medical centers. As I like to do in order to drive the point home about just how bad it’s become, I chose a couple of truly egregious examples of just how much quackery has infiltrated medical academia. First, I mentioned how the Cleveland Clinic has embraced reiki, which, as I’ve described many times before, is in reality faith healing that substitutes Eastern mysticism for Christian beliefs. Although I could have buried the audience in examples, the other example I happened to choose was this:
— Mayo Clinic (@MayoClinic) June 7, 2015
Yes, that is exactly what you think it is. It’s the official Twitter account of the Mayo Clinic promoting “energy therapies,” of which reiki is one of the most popular varieties. Basically, these are “therapies” in which it is claimed that the practitioner can either (1) manipulate the “life energy” fields of the patient (e.g., healing touch) or (2) channel “healing energy” into the patient from a source (e.g., reiki). And here was the Mayo Clinic promoting this magical mystical nonsense, linking to an article on its official website entitled “Energy Therapies Offer Support in Healing for Cancer Survivors“:
