We have an active comments section on our blog, but for some reason some people prefer not to comment there, but to send personal e-mails to authors when they disagree. Some of them make me laugh. Some of them make me despair. We can carry on our struggle better if we know what we are fighting; and in that spirit, I want to describe a recent e-mail exchange.
If an e-mail is filled with angry CAPITALS and abusive language, I know there is no point in responding. But I still get suckered in by the ones that start out sounding as if a productive dialog might be possible; unfortunately, discussions almost always degenerate. In this case, it started with a polite request for my opinion about a specific study. (more…)
On my recent trip to Nashville for CSICon, I took advantage of the long hours on the plane to read Breakthrough: Elizabeth Hughes, the Discovery of Insulin, and the Making of a Medical Miracle, by Thea Cooper and Arthur Ainsberg. One of our commenters recommended it. I’m not sure who (was it Chris?), but I want to thank you.
It’s the history of insulin told from the perspective of the scientists and of a typical patient, and it touches on a number of issues that we have addressed on SBM. It shows how science works to save lives, in stark contrast to the empty promises of CAM. (more…)
I was asked to write an article for Slate, the on-line magazine, about Andrew Weil’s selection as the keynote speaker for the 2012 AAFP annual scientific assembly. The science and health editor, Laura Helmuth, was initially enthusiastic about what I wrote, but eventually decided not to publish it. Here is the initial draft of my article. My comments follow.
Original Draft of Article for Slate
The American Academy of Family Physicians picked Andrew Weil to be the keynote speaker at its annual scientific assembly October 16-20 in Philadelphia. What were they thinking? That’s like having an astrologer give the keynote speech at an astronomy meeting.
The AAFP stands for the best in conventional medicine, for the standard of care as determined by physicians and scientists. Weil doesn’t. The AAFP stands for evidence-based medicine. Weil doesn’t. (more…)
In 2011, chiropractor J.C. Smith published The Medical War Against Chiropractors: The Untold Story from Persecution to Vindication. He promises an exposé comparable to Harriet Beecher Stowe’s exposé of slavery in Uncle Tom’s Cabin. His thesis is that the AMA waged a shameless attack on competition, motivated only by money. I think the reality is closer to what he quoted from Dr. Thomas Ballantine, Harvard Medical School:
The confrontation between medicine and chiropractic is not a struggle between two professions. Rather it is more in the nature of an effort by an informed group of individuals to protect the public from fraudulent health claims and practices.
The book is self-published, long-winded, repetitive, and flawed. It is a vicious screed crammed with bias, half-truths, insulting language, and innumerable references to Nazis and racial prejudice. In my opinion, Smith not only fails to make his case but degrades chiropractic.
A correspondent sent me a link to an article about the decision of the Wichita Falls (Texas) Independent School District to recommend that chiropractors be allowed to give sports physicals to junior high and high school students. Current policy limits examiners to physicians, physician assistants, and nurse practitioners. Adding chiropractors to this list would bring the district in line with policies in the rest of Texas, as well as in some other states. And it would “give parents more options.”
I’ve written about the attempts of some chiropractors to assume the role of family doctors and why I think it is a terrible idea. The idea of allowing them to do sports physicals impresses me as somewhat less terrible, but not by very much.
The Reasons for Requiring Sports Physicals
The goals of the Pre-participation Athletic Exam (PAE) include:
- To identify athletes who should not participate because of high risk of injury or death
- To identify those who require further evaluation or treatment so they can participate safely
- To identify conditions that do not affect athletic participation but that should be treated
- To possibly identify those at risk for substance abuse, depression, violence, etc.
- To provide preventive health advice
- To satisfy legal requirements. (more…)
The American Academy of Family Physicians journal American Family Physician (AFP) has a feature called Journal Club that I’ve mentioned before. Three physicians examine a published article, critique it, discuss whether to believe it or not, and put it into perspective. In the September 15 issue the journal club analyzed an article that critiqued the process for developing clinical practice guidelines. It discussed how two reputable organizations, the United States Preventive Services Task Force (USPSTF) and the American Academy of Pediatrics (AAP) looked at the same evidence on lipid screening in children and came to completely different conclusions and recommendations.
The AAP recommends testing children ages 2-10 for hyperlipidemia if they have risk factors for cardiovascular disease or a positive family history. The USPSTF determined that there was insufficient evidence to recommend routine screening. How can a doctor decide which recommendation to follow? (more…)
I intended to read Sam Kean’s new book The Violinist’s Thumb: And Other Lost Tales of Love, War, and Genius as Written by our Genetic Code just for fun. I was expecting a miscellany of trivia loosely gathered around the theme of DNA. But I found something much more worthwhile that I thought merited a book review to bring it to the attention of our readers. Kean interweaves entertaining stories into a somewhat disjointed but nonetheless valuable history and primer of genetics. The title refers to Paganini, whose DNA created the unusual joint flexibility that facilitated his unprecedented feats of virtuosity on the violin.
Being fat is bad except when it’s good. It’s called “the obesity paradox.” (No, that isn’t a mis-spelling for “two physicians who treat fat people.”) The adverse health effects of obesity are well established, but there are exceptions. Obesity appears to confer an advantage in certain subgroups with conditions like heart disease and diabetes.
In the News
Casual consumers of some recent media reports might interpret them as an excuse to stop trying to lose excess weight, especially if they are diabetic. Others might think we have been lied to about the dangers of the obesity epidemic. The reality is more complicated. (more…)
At the recent Amaz!ng (no, the ! is not a typo) Meeting in Las Vegas, Dr. Gorski, Dr. Novella, “Dr. Rachie” (Rachael Dunlop of Australia) and I participated in a workshop on “Dr. Google” about how to find reliable health information on the Internet. In my presentation, I described step by step how I researched a typical diet supplement product, Procera AVH. Later, one of our readers wrote to ask us about that very product, so I decided to convert part of my presentation into this blog post.
A half-page spread in my local newspaper proclaimed: “Memory Pill Does for the Brain What Prescription Glasses Do for the Eyes, Claims US Surgeon General Candidate.” It looked superficially like a news report, but it was actually an advertisement for the diet supplement Procera AVH. Closer inspection revealed the words “Paid advertisement” in tiny print, the required FDA disclaimer for diet supplements, a “Call Toll-Free” number and offers of a FREE Bonus Bottle, FREE book, and FREE supply of Rapid Detox Formula for First 500 Callers.

In 2005, cardiologist Barbara Natterson-Horowitz was called to the zoo to examine a non-human patient, an emperor tamarin with heart failure. She was surprised when the veterinarian told her not to look her patient in the eyes because eye contact could cause capture myopathy. In this condition, when an animal is captured, restrained, and feels threatened, there is a catastrophic surge of adrenaline that damages muscle tissues and can kill. It was described decades ago, but medical doctors don’t read the veterinary literature. It wasn’t until the early 2000s that American doctors began to recognize a similar phenomenon in human patients, takotsubo or stress-induced cardiomyopathy.
She began to wonder whether animals got other human diseases. She quickly learned that they did. Jaguars get breast cancer and may carry the same BRCA1 gene that plagues Ashkenazi Jewish women, rhinos get leukemia, penguins get melanoma, gorillas die from ruptured aortas, and koalas are in the midst of an epidemic of sexually transmitted chlamydia. Wild dragonflies infected with parasites become obese and develop a form of metabolic syndrome. Pretty much every human disorder occurs in animals too.
With the help of writer Kathryn Bowers, she distilled her findings into a book: Zoobiquity: What Animals Can Teach Us About Health and the Science of Healing. It’s a good read: informative, well argued, spiced with intriguing trivia, and more entertaining than a trip to the zoo. (more…)
