One of the most satisfying parts of being a health professional is the opportunity to help people make better health decisions. In between the emails suggesting I’m a paid lackey of the Pharmaceutical-Industrial Complex™ for not endorsing coffee enemas, vitamin C, or homeopathy, I do receive the occasional note thanking me for my advocacy, or for writing about a subject in a way they found helpful. I’m also sent questions – too many to answer, but occasionally opening my eyes to new “concepts” in alternative medicine. And while I spent years working in a pharmacy with a huge “holistic” health section, containing products that, if they worked, would have defied one or more laws of physics or chemistry, I can still be surprised at novel alternative-to-medicine approaches to health care. Last week I was sent a questions about hydrogen peroxide – not for first aid use (where it may not be as useful as thought), but for oral consumption, as some sort of health “cure-all”. I was baffled, but the concept does exist – and the Big Pharma Overlords apparently don’t want you to know about it. There must be a rule 34 of alternative medicine – if it exists, there is an (inappropriate) alternative medicine use for it. The active ingredient in hair bleach and teeth whitening strips is no exception. (more…)

I hate those oh hell moments. I was up way too late last night, but who can pass up the opportunity to see Patti Smith playing Horses (and more) for the 40th anniversary of the album. Only 44? Behind the Eagles? No way. I would nudge it up a few more spaces. Hard to believe I was 18 when that album came out. Horses is one of the few albums that made the transition from vinyl to CD. It was a tremendous show, and at 69 Patt performs with the energy and passion of a 29 year old. And she sure can spit. I had the evening off, so food and drinks at Swine until well past midnight. First time my wife and I closed a bar. I am too old for this.
But as I was blearily drinking my a.m. coffee on a dreary PDX morning, I opened the browser to SBM and there was a post by Jann. Oh hell. That means I have a post due tomorrow and I had lost track of the time over the holidays. I thought my next post was next Friday. Oh. Hell. So unlike most posts which I write over a week, this one was done in about 4 hours. And I am sure it will show.
How do you diagnose an infection?
Not always so simple. You always start with a history and, for infectious diseases, an exposure history is paramount. People get what they are exposed to, so you want to know travel, animals, diet, water, sex etc. If you have ridden a horse to have sex in an Indian lake while drinking raw milk (not really an unusual history in my practice; people do the darndest things) you have exposure risks for a variety of infections. If you have not left the Willamette Valley it is unlikely that the cause of the illness is malaria, although you always have to consider that the infection came to the patient rather than the other way around.

Joseph Mercola, D.O., runs the website mercola.com which is full of misinformation, advocates all kinds of questionable alternative treatments including homeopathy, and discourages vaccination and other aspects of conventional medicine.
Like Dr. Oz and Andrew Weil, he is more dangerous than easily recognizable quacks in that he combines some good medical information with egregious misinformation, and readers who know he is right about the good information are likely to wrongly assume everything else he says must be equally true. He’s right about some things, but the safest course is to assume that anything on his website is false unless you can verify it as true by consulting other sources that are reliable. I tried to verify the information in his recent article on colonoscopy. I found outright errors along with fear-mongering and bias. (more…)
“May your epididymitis be treated with acupressure by André the Giant!”
The new year is upon us, and with it comes a unique opportunity for the Science-Based Medicine team to look deep into our crystal balls, to channel our Atlantean spirit guides, and to ride the waves of cosmic consciousness in order to bring to you our predictions for 2016. But before you scoff at our collective powers of prognostication, know that we have never made a prediction that has not come to pass. We’ve also never made any official predictions before, but that’s neither here nor there.
In the process of discussing what will become of this new alternative medicine fad (have you heard of it?) in the coming year, I have discovered that the contributors to SBM are all extremely pessimistic. Sadly, the vast majority of the responses to my request for predictions were focused on the future advances of pseudoscience in medicine and the steady decline of our ability to tell the difference between reality and medical fiction. But I agree with each and every one. (more…)
Listen to your science: Eat your vegetables.
This is an expansion of a post I did over on the Society for Science-Based Medicine blog about this time last year. The original post, which got far more traffic than is usual for the SFSBM, is a good example of how science works and the good that it can do. The hard work of real science illustrated here serves as a striking counterpoint to the slap-dash system of pseudoscience, which churns out fake diseases, causes, and cures by the dozen based on a fuzzy understanding of real science fueled by a healthy dose of imagination.
Naturopaths and “functional medicine” practitioners would have the public believe that they are the true experts on nutrition and health. Even though their nutritional advice contains a large serving of hooey and a big helping of dietary supplements, which they are happy to sell to patients.
So it was with great interest that I read the obituary of Dr. Lee Wattenberg in the New York Times.
Dr. Wattenberg published a landmark paper in the journal Cancer Research that reviewed 36 years of animal studies on the effects that certain compounds had on the development of cancer. The paper laid the framework for understanding how these compounds work. . . .
He showed that cabbage, brussel sprouts, cauliflower and broccoli inhibit the development of carcinogens. He isolated a compound in garlic that decreased “by a factor of three” the chances that animals injected with cancer agents would develop that cancer. He found two chemicals in coffee that neutralize free radicals, which are harmful chemicals commonly implicated in the onset of cancer.
I’ve frequently noted that one of the things most detested by quacks and promoters of pseudoscience is peer review. Creationists hate peer review. HIV/AIDS denialists hate it. Anti-vaccine cranks like those at Age of Autism hate it. Indeed, as a friend of mine, Mark Hoofnagle, pointed out several years ago, pseudoscientists and cranks of all stripes hate it. There’s a reason for that, of course, namely that it’s hard to pass peer review if you’re peddling pseudoscience, although, unfortunately, with the rise of “integrative medicine,” it’s nowhere near as difficult as it once was.
Be that as it may, peer review, the process by which scientific papers are evaluated by scientific “peers” to look for problems with the science and decide if the paper is appropriate for publication in a scientific journal, is a concept that dates back hundreds of years. However, for the most part, before the middle of the 20th century, the ultimate determination of whether a paper was appropriate for scientific publication was made by editors or editorial committees. Opinions of external reviewers were sometimes sought when deemed appropriate by journal editors, but by no means was this the practice for most manuscripts. Over the last six or seven decades, external peer review by scientists chosen by the journal editor evaluating a submission has become the standard. Similarly, decisions regarding whether or not to fund grant applications are now generally made by a panel of external reviewers. In the case of the NIH, these panels are called study sections and consist of scientists with expertise in the types of applications being referred to the study section for evaluation, along with (usually) a statistician or two and officials from the NIH who take care of organizing and running the meetings of the panel. The scientific members of a study section usually include “permanent” members, who are assigned to fixed terms on the study section, and ad hoc members, called in for one or a few meetings as needed and deemed necessary by the NIH.
Editor’s note: This post is a collaborative effort between Grant Ritchey, a Science-Based Medicine semi-regular, and Stephanie Tornberg-Belanger, a co-author of the research paper discussed below and who brought the study to Grant’s attention. We are pleased to welcome Stephanie as a guest contributor to SBM.
That amazing coconut oil! What can’t it do?
In his last SBM post, Grant reported on a systematic review of the literature that undermined just about everything dentists had been taught in dental school and have been preaching to patients since The Olden Times: flossing, as it turns out, is not the be-all, end-all that we’ve been led to believe with regard to cavity and gum disease prevention. While the message itself was interesting and relevant, the meta-message in that piece is that we all must be willing to slay our own sacred cows when the evidence demands it, even if it requires shedding long-held, cherished beliefs. This is difficult for any human being to do, and skeptics who are presumably open minded are no different (and can sometimes be worse, because we are often overconfidently convinced of our “rightness”).
So with that in mind, gather ’round children, because we have another meta-message for you. This one deals with coconut oil.

Chelation with intravenous EDTA (disodium ethylene diamine tetra-acetic acid) has long been used for heavy metal poisoning. It binds the metal ions and facilitates their excretion from the body. In recent years it has been used for many other indications that are not evidence-based, such as autism and coronary heart disease.
The Trial to Assess Chelation Therapy (TACT) was done to assess the effectiveness and safety of EDTA plus high-dose oral vitamins for preventing second heart attacks in patients who had already had one. An article on The People’s Pharmacy website portrays the study as strongly positive. The Graedons, authors of the website, claim that science supports the use of chelation. They report that for every 12 patients undergoing chelation, one heart attack will be prevented over a five-year period. They cite a 5-year NNT (number needed to treat) of 16 for statin therapy and they conclude that:
EDTA chelation outperformed statins because fewer people needed to receive treatment to achieve a desirable outcome.
While it is both easy and fun to point out the inadequacies of unscientific modalities such as chiropractic and homeopathy, our goal at Science-Based Medicine is the application of a single standard to all medical practice, even if it stings a bit. We are far from perfect. While I firmly believe that most conventional healthcare professionals are good people who strive to provide the best care possible for their patients, I accept that there is room for improvement and pediatric medicine is certainly no exception.
In fact, one of the characteristics that best distinguishes conventional from so-called alternative medicine is the simple fact that we systematically attempt to recognize and correct our errors on an individual and system wide level. That we evolve in the light of new and better evidence, albeit sluggishly as a rule rather than an exception, allows me to sleep at night. There is no quality control in alternative medicine. There are only shifting trends in the marketing of nonsense to the curious, desperate, and gullible. (more…)
