Chiropractic and Deafness: Back to 1895
Chiropractic originated in 1895 when D.D. Palmer claimed to have restored deaf janitor Harvey Lillard’s hearing by manipulating his spine. This makes no anatomical sense, and few if any chiropractors claim to be able to reverse deafness today. But now a chiropractic website is attempting to vindicate D. D. Palmer. They list deafness among a long (wrong) list of “Conditions That Respond...
Science-Based Medicine Meets Medical Ethics
There are four main principles in medical ethics: Autonomy Beneficence Non-maleficence Justice Autonomy means the patient has the right to consent to treatment or to reject it. Autonomy has to be balanced against the good of society. What if a patient’s rejection of treatment or quarantine allows an epidemic to spread? Beneficence means we should do what is best for the patient....
Incorporating Placebos into Mainstream Medicine
Alternative medicine by definition is medicine that has not been shown to work any better than placebo. Patients think they are helped by alternative medicine. Placebos, by definition, do “please” patients. We would all like to please our patients, but we don’t want to lie to them. Is there a compromise? Is there a way we can ethically elicit the same placebo...
Is Tylenol Safe?
Tylenol (acetaminophen, also known as paracetamol outside the US) has been in the news recently. Most of the stories I’ve seen have been accurate, but I’ve run across a couple of people who misunderstood what they read. I thought I’d try to put the record straight. An FDA advisory panel has recommended reducing the maximum allowed single dose from 1000 mg to...
Birth Day
So many of the posts on this blog are critical and deal with examples of poor science or other problems. I’d like to offer a breath of fresh air in the form of a book by Mark Sloan, MD: Birth Day: A Pediatrician Explores the Science, the History, and the Wonder of Childbirth. It is a very positive book. Sloan has attended...
Healing Touch and Coronary Bypass
A study published in Alternative Therapies in Health and Medicine is being cited as evidence for the efficacy of healing touch (HT). It enrolled 237 subjects who were scheduled for coronary bypass, randomized them to receive HT, a visitor, or no treatment; and found that HT was associated with a greater decrease in anxiety and shorter hospital stays. This study is a...
Screening Tests – Cumulative Incidence of False Positives
It’s easy to think of medical tests as black and white. If the test is positive, you have the disease; if it’s negative, you don’t. Even good clinicians sometimes fall into that trap. Based on the pre-test probability of the disease, a positive test result only increases the probability by a variable amount. An example: if the probability that a patient has...
Science under Siege
A new book, Science Under Siege: Defending Science, Exposing Pseudoscience addresses many of the issues near and dear to the hearts of SBM bloggers and readers. A compilation of some of the best writing from the last few years of Skeptical Inquirer magazine, it’s not only good reading but can serve as a useful reference. Skeptical Inquirer is the official magazine of...
Vaccines and Autism: A Deadly Manufactroversy
I was recently asked to write about vaccines and autism for Skeptic magazine. I approached the project with trepidation. So much has been written, from Paul Offit’s book Autism’s False Prophets to a veritable flood of blogorrhea on the Internet. I didn’t have anything new to add, and I couldn’t hope to cover all aspects of the subject. After some thought, I...
