We have written a lot about people who reject science-based medicine and turn to complementary/alternative medicine (CAM), but what about people who reject the very idea of medical treatment?
Faith healing is widely practiced by Christian Scientists, Pentecostalists, the Church of the First Born, the Followers of Christ, and myriad smaller sects. Many of these believers reject all medical treatment in favor of prayer, anointing with oils, and sometimes exorcisms. Some even deny the reality of illness. When they reject medical treatment for their children, they may be guilty of negligence and homicide. Until recently, religious shield laws have protected them from prosecution; but the laws are changing, as are public attitudes. Freedom of religion has come into conflict with the duty of society to protect children. The right to believe does not extend to the right to endanger the lives of children. A new book by Cameron Stauth, In the Name of God: The True Story of the Fight to Save Children from Faith-Healing Homicide, provides the chilling details of the struggle. He is a master storyteller; the book grabs the reader’s attention like a fictional thriller and is hard to put down. He is sympathetic to both the perpetrators and the prosecutors of religion-motivated child abuse, and he makes their personalities and their struggles come alive. (more…)
Sally Satel and Scott Lilienfeld have written a new book, Brainwashed: The Seductive Appeal of Mindless Neuroscience. Its purpose is not to critique neuroscience, but to expose and protest its mindless oversimplification, interpretive license, and premature application in the legal, commercial, clinical, and philosophical domains.
The brain is a wondrous thing: “…the three pound universe between our ears has more connections than there are stars in the Milky Way.” Trying to understand how it works and how it generates conscious awareness and subjective feelings is a daunting task. Neuroimaging is one of the tools we are using to study it. Unfortunately, people get so enthusiastic about its possibilities that they are constantly tempted to read more into the images than is really there. This has given rise to a new phrenology that interprets our mental characteristics with pretty colored pictures. We are easily impressed by pictures; after all, a picture is worth a thousand words.
Brain imaging can’t show us what is going on in the mind of the person. It shows areas that have increased oxygen consumption. A spot lights up when a person thinks or acts, but that doesn’t tell us much. Single blobs that light up in the brain have been interpreted as centers for things like love, rewards, hate, and belief in God. This is sometimes referred to as “blobology.” They found an area in one person that lit up when he thought about an actress he loved. That area was thought to be a “reward” center. But it also lit up when he thought of Ahmadinejad! So they did some fancy footwork and rationalized that he believed that the Jewish people would endure and therefore he derived pleasure from the idea that Ahmadinejad would fail. That’s pretty far-fetched. Occam’s razor would suggest that maybe the area that lit up was reacting not to pleasure, but to something else. People tend to read what they want to see into ambiguous patterns like a Rorschach test. Mental functions are rarely limited to a single spot in the brain; multiple areas are involved and interconnected. Researchers are increasingly moving away from blobology and towards pattern analysis where they look at the patterns of activation across the entire brain. (more…)
People have been living on earth for about 250,000 years. For the past 5,000 healers have been trying to heal the sick. For all but the past 200, they haven’t been very good at it.

Twenty years is a long time in medicine. I celebrated my 20th pharmacy class reunion last weekend. Of course reunions are time to reflect back to our early years as pharmacists. Lots has changed. Much of the therapeutics I was taught is now obsolete. In 1993, HIV was a death sentence and there were only three, largely ineffective drugs available. Thanks to new drugs, HIV can now be managed like a chronic disease, and some of my colleagues have HIV-focused pharmacy practices. The same dramatic changes have occurred in fields like cancer and transplant medicine. And in some cases, the cause of disease has become more clear – my old textbooks make no mention of Helicobacter pylori as a cause of ulcers.
The practice of pharmacy has changed, too. On the positive side, pharmacists are working in new settings where they can focus on medication management, and not just dispensing prescriptions. Regulators are granting pharmacists the ability to take on new roles, and pharmacists are being compensated for more than simply “count, pour, lick and stick.” From that perspective, it’s a promising time to be a pharmacist. But there’s a much more disturbing side to the profession that’s emerging, too. Community (retail) pharmacy practice is under pricing and competitive pressure, and smaller pharmacies are being subsumed into big retailers where the pharmacy department is buried in the back – a loss leader to bring in patients, but hardly with a health-care focus. And most disturbingly, I see a move within retail pharmacy practice to leverage its professional credibility to sell all types of modern-day snake oil, ranging from detox kits and “cleanses” to dubious “food intolerance” testing. Homeopathic remedies (an elaborate placebo system of sugar pills) are increasingly found on pharmacy shelves, alongside real medicine. And don’t forget the enormous wall of vitamins that seems to get larger and larger. Yes, complementary and alternative medicine is booming, and pharmacy wants its share. Pharmacy regulators turn a blind eye. What do my pharmacy colleagues tell me? They’ll tell me it’s customer demand, and that they don’t recommend the quackery. To me, I see this trend as damaging the credibility of pharmacists in the eyes of the public and of other health professionals. (more…)
Doctors are often accused of being unfeeling technicians who treat their patients like cases of disease rather than people (think Dr. House). We were taught in medical school to remain detached, not get too close to patients, and not show our emotions. That attitude was epitomized in William Osler’s essay Aequanimitas. But doctors have feelings like anyone else, and no one is Spockishly rational. A patient might reasonably say “I don’t give a damn how my doctor feels as long as she gets me better,” but emotions affect everything we do, influencing clinical decisions and patient outcomes. This subject is investigated in a new book, What Doctors Feel: How Emotions Affect the Practice of Medicine, by Danielle Ofri, MD, PhD, an associate professor of medicine and an accomplished writer who has written extensively about her experiences in medicine.
She tells anecdotes from her training to give the reader a feel for what it was like to be in an extremely stressful situation with time pressure, conflicting duties, lack of sleep, life-or-death responsibilities, the highest expectations, and the impossibility of both getting everything done and doing each thing well. It reminded me of times in my own training when I desperately wanted to just somehow survive the day and not kill anyone. Medical residency can be almost as stressful as a war zone, and has its own PTSD victims, complete with flashbacks.
Part of the stress is being suddenly immersed in a new culture with its own tribal customs, slang, in-jokes, and a foreign language: “82WM w/PMH of CAD, CVA, MIx2, s/p 3V-CABG, c/o CP, SOB 2 wks PTA. BIBA s/p LOC. No F/C/N/V/D.” (more…)
A correspondent asked for my opinion of a new book by journalist Jennifer Margulis that is apparently getting a lot of attention in some circles: The Business of Baby: What Doctors Don’t Tell You, What Corporations Try to Sell You, and How to Put Your Pregnancy, Childbirth, and Baby Before Their Bottom Line. I got a copy from the library and read it. It was a painful experience. One of the customer reviews on the Amazon website accurately sums up my own reaction:
There is a great need for an incisive look at all sides of modern maternity care in the United States, because — let’s face it — we all know it’s not perfect. This, however, is not that book.
The author is a strong advocate of home birth, water birth, midwives, “embracing the pain to make you stronger,” “parents know better than doctors,” natural = good, and very early potty training. She thinks bathing a newborn is harmful. She questions the need for well baby checkups: she thinks they are mainly a gimmick to sell vaccines. She questions the (science-based) practice of giving newborns vitamin K and prophylactic eye drops. She is against the use of chemicals in general. She reports that Johnson’s Baby Wash contains “a host of unpronounceable chemicals, some of which are known toxins…and carcinogens.” She doesn’t seem to have grasped the basic principle of toxicology that the poison is in the dose. She is against formula, which she says is killing babies, and against disposable diapers because they contain chemicals and petroleum and because they can cause your child to become infertile. Her only evidence for “infertility” is one study showing that disposable diapers raise scrotal temperatures. Indeed, plastic underpants are probably warm.
Ever heard of George Augustus Scott? Probably not. Although he was once touted as “Man of the Century,” he was actually a charlatan who sold electric hairbrushes. (No, an electric hairbrush isn’t a device that will brush your hair for you; it’s a hairbrush that supposedly produces a “permanent electric current” to cure everything from baldness to headaches.) He went on to sell magnetic corsets, electric rings for rheumatism, and sarsaparilla, advertised as the “GREATEST MEDICAL DISCOVERY of the AGE.” (You probably haven’t heard about that greatest discovery either.)
He and his many comrades in crime are profiled in a new book, The Medical Electricians: Dr. Scott and his Victorian Cohorts in Quackery by Robert K. Waits. You will find more quacks in this book than in any duck pond. It provides historical insights and reminds us that there is nothing new under the sun; similar charlatans continue to sell similar quack devices today, facilitated by the Internet and other media.
Electricity and magnetism sounded exciting to Victorian ears, but their properties were poorly understood. Great hopes were raised for medical applications. The opinions of experts varied. Priestly reported experiments from Italy and Germany in 1747-8 showing that a patient who held a vial of medicine while being electrified would get the same benefit as if he took the medicine by mouth. Benjamin Franklin, on the other hand, was persuaded that these reports were not true. (more…)
Sometimes, between blogging, a demanding day (and night) job doing surgery and science, and everything else, I embarrass myself. Sure, sometimes I embarrass myself by saying something that, in retrospect, I wish I hadn’t. More often, I embarrass myself by letting things slide that I shouldn’t. For instance, when friends send me a prepublication copy of their books, I should damned well read them, don’t you think? So it was that Paul Offit sent me a copy of his latest book, which just hit the bookstores and online outlets this week, Do You Believe in Magic? The Sense and Nonsense of Alternative Medicine, and I haven’t finished it. Oh, I’ve read a good chunk of it, but it’s not a huge book (around 335 pages); so I should have finished it by now, particularly since it’s quite good. My failure to properly read and plug the book aside, I’m glad to see that the book’s getting attention in a large media outlet, namely USA Today, in an article by Liz Szabo Book raises alarms about alternative medicine. There’s also a companion piece How to guard against a quack. I figure that the least I can do is to plug Dr. Offit’s book and the USA Today story in which he is featured, just as Harriet plugged his recent speaking appearance.
It’s also nice that Steve Novella and I were both interviewed. Now, excuse me while I get back to doing what I really should have had finished a month or two ago: Reading Dr. Offit’s excellent book.
In the past I have criticized evolutionary medicine for its tendency to rely on unverifiable “Just-So Stories,” but a new book has helped me appreciate what the best kind of evolutionary thinking can contribute to our understanding of medicine. Doves, Diplomats, and Diabetes: A Darwinian Interpretation of Type 2 Diabetes and Related Disorders by Milind Watve investigates diabetes from an evolutionary perspective, suggesting how it might have originated, why it persisted, and how it is related to survival advantages. Watve develops well-reasoned hypotheses that can be tested by examining their expected consequences. He believes it is impossible to understand metabolism without understanding behavioral ecology, and he makes a good case.
A reassessment of the evidence concerning Type II diabetes (T2D) reveals a number of paradoxes. Elevated blood glucose is the defining feature of T2D but controlling it doesn’t prevent all the complications of diabetes, and it doesn’t appear that elevated blood sugar could produce all the pathological changes of diabetes. Insulin resistance is believed to be central to a cluster of deadly diseases in humans, but in other animals it has no adverse effects on health and even increases lifespan. Studying diabetes from an evolutionary perspective can shed light on such paradoxes. (more…)
I write about a lot of depressing subjects, and sometimes a change of pace is welcome. Mary Roach, billed as “America’s funniest science writer,” has followed up on her earlier explorations of cadavers (Stiff), sex (Bonk), the afterlife (Spook), and survival on spaceships (Packing for Mars) with a new book entitled Gulp: Adventures on the Alimentary Canal.
Forget all that mythology about diet, detoxification, and 10-year-old hamburger accretions in the bowel. The reality of human digestive physiology is far more interesting and has the extra-added attraction of being true. And in Roach’s hands, often howlingly funny. She is a hands-on investigative reporter who is ready to try anything; among other adventures she inserts her entire arm in a cow’s stomach. Her highly entertaining odyssey takes her to Igloolik to eat narwhal skin, to a dog food tasting lab in Missouri, to Minnesota to observe a fecal transplant, and to strange and exotic outposts at the cutting edge of science, populated by colorful characters.
