Tylenol May Not Be As Safe and Effective As We Thought
I’ve always thought of Tylenol (AKA acetaminophen in the US and paracetamol in the UK) as one of the safest drugs around, with essentially no side effects when used as directed. But it has been in the limelight lately. Several SBM articles have addressed it here, here, and here. We know there is a risk of liver damage and death with acetaminophen...
How to Think
Robert Todd Carroll, the author of The Skeptic’s Dictionary, has a new book out: The Critical Thinker’s Dictionary: Biases, Fallacies, and Illusion and what you can do about them. Since some of our commenters and most of the CAM advocates we critique are constantly committing logical fallacies, a survey of logical fallacies is a good idea both for us and for them,...
Food for Thought
I am excited to tell you about a wonderful new endeavor that is helping to promote critical thinking about science and medicine. It’s a free online course on “Food for Thought” that offers a scientific framework for understanding food and its impact on health and society from past to present. The “Food for Thought” course is a product of EdX, which offers...
Washington State’s Unconscionable, Unconstitutional Child Protection Law
I recently wrote about the conflict between child protection and the religious freedom of believers in faith healing. That issue has reared its ugly head again in the state of Washington. Washington law currently denies the children of Christian Scientists equal protection under the law governing child abuse and neglect, and it grants a special exemption from criminal prosecution for abuse and...
Top 10 Chiropractic Studies of 2013
ChiroNexus recently listed the top 10 chiropractic studies of 2013. In my experience, chiropractic studies tend to be of poor quality. A media report says “study shows chiropractic works for X,” and when I look for the study it turns out to be a single case report or an uncontrolled study. When Simon Singh was sued by the British Chiropractic Association for...
Tribalism and Medical Ethics
Science is intended to discover the “is”, not the “ought;” facts, not values. Science can’t tell us whether an action is moral; it can only provide evidence to help inform moral decisions. For instance, some people who believe abortion is immoral reject birth control methods that prevent implantation of a fertilized ovum on the grounds that it constitutes abortion; science can determine...
Vitamin E for Alzheimer’s
Recently you may have seen headlines like “Vitamin E slows decline in patients with mild Alzheimer’s” or “There’s still no cure for Alzheimer’s disease, but the latest hope for slowing its progression is already on drugstore shelves.” They were referring to an article in the January 1, 2014 issue of the Journal of the American Medical Association (JAMA) announcing the results of...
Doctors Are Not “Only Out to Make Money”
There’s an old joke about the doctor whose son graduates from medical school and joins his practice. After a while the son tells his father, “You know old Mrs. Jones? You’ve been treating her rash for years and she never got better. I prescribed a new steroid cream and her rash is gone!” The father responds, “You idiot! That rash put you...
Garcinia Probably Works But Is Far From a Weight Loss Miracle
Women make up a majority of Dr. Oz’s audience. The majority of women would like to lose weight. That is a match made in heaven, a marketer’s dream. And Oz has never hesitated to exploit that fact to increase audience share, playing fast and loose with sensationalized evidence instead of giving his viewers science-based advice. Dr. Oz has promoted a series of...
And Now for Something Completely Different
This will be a departure from my usual posts. Several announcements in the news and medical journals have caught my attention recently, and as I delved into the details, I thought I would share them with our SBM readers. Topics include AIDS cures, the continuing danger of polio, eating nuts for longevity, racial differences in vitamin D, and the use of pharmacogenetic...
