An article (and associated news video clip) from ClickOn in Detroit is titled “Alternative treatment helps Michigan doctor beat infertility.” This is a misleading title, and the report is an example of poor science reporting.
Was She Infertile?
The patient in question was a 33-year-old family practice doctor who believed she was infertile. By definition, infertility is failure to conceive after a year of regular intercourse without contraception. She didn’t meet that definition. She only tried for 6 months before seeing a doctor, and then for 2 more months (with some kind of unspecified medicine) and then she consulted a reproductive endocrinologist who apparently told her she was infertile because of a high FSH level. Then she “did her own research” and supposedly found that acupuncture was a key part of infertility treatment. So she sought infertility treatment from an acupuncturist.
Please note: the following refers to routine physicals and screening tests in healthy, asymptomatic adults. It does not apply to people who have been diagnosed with diseases, who have any kind of symptoms or signs, or who are at particularly high risk of certain specific diseases.
Throughout most of human history, people have consulted doctors (or shamans or other supposed providers of medical care) only when they were sick. Not too long ago, the “if it ain’t broke don’t fix it” mindset changed. It became customary for everyone to have a yearly checkup with a doctor even if they were feeling perfectly well. The doctor would look in your eyes, ears and mouth, listen to your heart and lungs with a stethoscope and poke and prod other parts of your anatomy. He would do several routine tests, perhaps a blood count, urinalysis, EKG, chest-x-ray and TB tine test. There was even an “executive physical” based on the concept that more is better if you can afford it. Perhaps the need for maintenance of cars had an influence: the annual physical was analogous to the 30,000 mile checkup on your vehicle. The assumption was that this process would find and fix any problems and insure that any disease process would be detected at an early stage where earlier treatment would improve final outcomes. It would keep your body running like a well-tuned engine and possibly save your life.
We have gradually come to realize that the routine physical did little or nothing to improve health outcomes and was largely a waste of time and money. Today the emphasis is on identifying factors that can be altered to improve outcomes. We are even seeing articles in the popular press telling the public that no medical group advises annual checkups for healthy adults. If patients see their doctor only when they have symptoms, the doctor can take advantage of those visits to update vaccinations and any indicated screening tests.
Remember the movie “Attack of the Killer Tomatoes”? That was fiction, but some alarmists would have us believe that the tomatoes and potatoes on our plates are really out to get us.
I recently got an e-mail inquiry from an MD who said he had read that solanine in tomatoes, potatoes, and eggplants could be responsible for essential hypertension and a number of GI complaints, as well as symptoms of rheumatoid arthritis, apparently through their inhibition of acetylcholinesterase. He had looked for supporting scientific studies and hadn’t found any. He wondered if I had seen any such studies. I looked too. I couldn’t find any either.
Applied kinesiology (AK) was briefly mentioned in Scott Gavura’s article on Food Intolerance Tests last week. Since AK is arguably the second silliest thing in CAM after homeopathy, I thought it wouldn’t hurt to say a little more about it.
A press release on the Wall Street Journal website recently announced that a chiropractor in Illinois was offering “Nutrition Response Testing”
…to help patients optimize overall health…[the test] determines the specific balance of nutrients necessary to optimize metabolic function at the cellular level… the chiropractor then uses this information to make nutritional recommendations for patients…[the test] provides precise feedback that can also help identify the underlying cause for chronic pain and illness.
Note: The James Randi Educational Foundation (JREF) is publishing a new series of e-books. The first two offerings are an excellent new book on critical thinking by Bob Carroll, Unnatural Acts, and the first in a planned series of republications of classic skeptical works, Homeopathy and Its Kindred Delusions, by Oliver Wendell Holmes. I was asked to write the introduction for the latter, and the JREF has kindly given their permission for me to reproduce it here.
The German philosopher Hegel said, “We learn from history that we don’t learn from history.” “Homeopathy and Its Kindred Delusions” is a remarkable little book based on two lectures Oliver Wendell Holmes gave in 1842. It is a masterful debunking of homeopathy. If his lessons had been taken to heart, homeopathy would not have survived and we could have avoided a great number of other medical delusions that continue to plague us today, both from charlatans and from well-meaning advocates who lack Holmes’ critical thinking skills.
To realize just how remarkable this book is, imagine the world of 1842. Samuel Hahnemann, the inventor of homeopathy, was still alive. Roentgen wouldn’t discover x-rays until 1895. The germ theory was not yet established. Semmelweis wouldn’t make his observations on puerperal fever until 3 years later. It wasn’t until 1854 that John Snow removed the Broad Street pump handle and stopped a cholera epidemic. Koch’s postulates for determining infectious causes of disease weren’t published until 1890. Doctors didn’t wash their hands or use sterile precautions for surgery. Bloodletting to “balance the humors“ was still a common practice. The randomized placebo-controlled trial wouldn’t appear for another century. Contemporary medicine often did more harm than good. In fact, Holmes himself famously quipped “I firmly believe that if the whole materia medica could be sunk to the bottom of the sea, it would be all the better for mankind and all the worse for the fishes.” (more…)
In writing about science-based medicine, we give a lot of attention to medicine that is not based on good science. We use bad examples to show why science is important and how it is frequently misapplied, misinterpreted, misreported, or even wholly rejected. It’s a pleasure, for a change, to write about a straightforward example of the best of science-based medicine in action. The book Heart 411 is such an example.
The medical literature is a jungle of conflicting and complicated studies. It’s difficult for novices and even for sophisticated non-specialists to navigate. It’s useful to have experts as guides who can apply their knowledge, experience, and judgment to analyze the data and put everything into perspective. I can’t imagine anyone more qualified as guides to “matters of the heart” than the authors of this book. Heart surgeon Marc Gillinov and cardiologist Steven Nissen practice at the Cleveland Clinic, which has been ranked as the number one heart hospital by U.S. News & World Report for the last 15 years and is currently ranked 4th best hospital overall. They have treated more than 10,000 heart patients over 30 years of clinical practice and have also done extensive research and published hundreds of articles in peer reviewed journals. Their book contains everything they would like their patients to know about the prevention, diagnosis, and treatment of heart disease. It amounts to an owner’s manual for the heart. (more…)
Many years ago, when I was a naïve and gullible teenager, I read about a home treatment for constipation that involved rolling a bowling ball around on the abdomen. I was intrigued, thought it sounded reasonable, and might even have tried it myself if I had been constipated or had had a bowling ball to experiment with. Many decades later, with the advantages of a medical education and experience in science-based medicine and critical thinking, I encountered a treatment that reminded me of the bowling ball: visceral manipulation (VM), a practice developed by a French osteopath and physical therapist, Jean-Pierre Barral. This time I was far more skeptical. VM may be more sophisticated than a bowling ball, but its effectiveness and safety are equally dubious.
Visceral manipulation (VM) will probably be unfamiliar to most of my readers, but its promoters say it has been adopted by osteopathic physicians, “allopathic” physicians, doctors of chiropractic, doctors of Oriental medicine, naturopathic physicians, physical therapists, occupational therapists, massage therapists and other licensed body workers. Its origin follows the path of many other alternative health systems. Like chiropractic, ear acupuncture, iridology, EMDR, and others, it was developed by one individual based on his personal observations and experiences without any kind of proper testing. Like the others, it started with a single patient: in Ignaz von Peczely’s case an owl with a spot on its iris, in D.D. Palmer’s case a janitor whose hearing allegedly improved after something was done to his back, in Barral’s case a patient who said he had felt relief from his back pain after going to an “old man who pushed something in his abdomen.” From a single case they extrapolated to a general belief about disease causation and a whole diagnostic and/or treatment system.
How is VM Done?
A video shows Barral demonstrating his skills. He “listens with his hands” to detect tension (elsewhere the perception is designated as a thermal phenomenon). His diagnostic process begins by “listening with the hands” on the top of the patient’s head to determine the lateralization or general area of the problem. Then his hands “listen” to the areas of concern to further localize the problem. In this demonstration he detects something in the stomach which he says could be from decreased acidity or emotional tension. Then he listens to the skull repeatedly with both hands, does something simultaneously to the neck and abdomen, and finally he is satisfied that his hands are telling him that he has corrected the problem.

A Navy neurologist, Capt. Elwood Hopkins, has posted a 3-part article on “The Power of Acupuncture” on Navy Medicine Live, the official blog of Navy and Marine Corps Health Care. It can serve as a useful lesson in how not to think about medicine. It is a prime example of how an intelligent, educated doctor can be fooled and can fool himself into thinking that a placebo is an effective treatment.
To set the scene: acupuncture has been increasingly accepted in military circles. The Air Force is teaching its doctors “battlefield acupuncture” based on the faulty evidence of one Air Force doctor, Richard Niemtzow. The Army is using it to treat PTSD. The Navy offers it too.
Hopkins says that after 40 years of practicing neurology, “It was only natural to begin thinking about something else.” (Why? Boredom? And why pick acupuncture?) When he got an e-mail from his Specialty Leader announcing the opportunity for Navy doctors to learn how to do acupuncture, he submitted his application that same day. He was undoubtedly impressed that this training was being offered by the Navy, lending it the imprimatur of authority. His prior impression of acupuncture was that it was a “mysterious tool” that seemed to work; and instead of asking critical questions, he says he was looking for “a fundamental scientific understanding of acupuncture” and asking to see the supporting research and data.

Critics of mainstream medicine often point to the dangers of drugs. I previously wrote about “Death by Medicine,” where I explained the fallacy of fixating on harmful effects of drugs without putting them into perspective with all the good drugs do. Yes, patients have died from severe allergic reactions to penicillin, but penicillin has also saved countless lives.
A recent article in The New England Journal of Medicine looks at emergency hospitalizations for adverse drug events in elderly Americans. It confirms that adverse reactions are a serious problem, but some of its findings are surprising.
A number of buzz-words appear repeatedly in health claims, such as natural, antioxidants, organic, and inflammation. Inflammation has been implicated in a number of chronic diseases, including diabetes, Parkinson’s, rheumatoid arthritis, allergies, atherosclerosis, and even cancer. Inflammation has been demonized, and is usually thought of as a bad thing. But it is not all bad.
In a study in Nature Medicine in September 2011, a research group led by Dr. Umut Ozcan at Children’s Hospital Boston (a teaching hospital affiliated with Harvard Medical School) reported that two proteins activated by inflammation are crucial to maintaining normal blood sugar levels in obese and diabetic mice. This could be the beginning of a new paradigm. Ozcan says:
This finding is completely contrary to the general dogma in the diabetes field that low-grade inflammation in obesity causes insulin resistance and type 2 diabetes. For 20 years, this inflammation has been seen as detrimental, whereas it is actually beneficial.
Increasing levels of these inflammatory signals might actually be therapeutic in diabetes and obesity. On the other hand, they might worsen inflammatory diseases like asthma and rheumatoid arthritis. Ozcan’s findings are intriguing and might eventually lead to new treatments, but there are no clinical applications as yet.
