Craniosacral Therapy Is Bogus but DOs Are Required to Learn It

The standard textbook used in many schools of osteopathic medicine includes a lamentable chapter on cranial manipulation. It is clearly biased and fails to meet the minimal standards of science-based medicine. Craniosacral manipulation therapy is bogus, and it should no longer be taught to DOs or feature on their exams. Craniosacral therapy (CST) is practiced

A Blood Test for Fibromyalgia?

The FM/a test is advertised as a definitive test to diagnose fibromyalgia. It isn’t definitive. It is expensive. It has not been shown to change patient outcomes. I was surprised to learn that there is a blood test to diagnose fibromyalgia, the FM/a test. Is it accurate? Is it useful? Fibromyalgia is still a disputed

Covid-19 Tests: Can You Trust the Results?

If your Covid-19 test was negative, can you breathe a sigh of relief? What if it’s a false negative? If it was positive, is that reliable evidence of infection or might it be a false positive result? How trustworthy are these tests? As with so much in science, the answer is complicated; it’s not a

Melanoma: A Pseudoepidemic of Skin Cancer Prompts New Screening Recommendations

There appeared to be an epidemic of melanoma skin cancer, but it seems to be a pseudoepidemic caused by overdiagnosis. Screening everyone with skin exams does more harm than good and can no longer be recommended. This lesion was suspicious enough to warrant a biopsy, but screening everyone for skin cancer is not warranted. Screening

Is Midstream Urine Collection Necessary?

There’s considerable evidence that the standard procedure for urine specimens, with cleansing and mid-stream collection, may not be necessary. Is it time to change? In November 2020, I reviewed Paul Offit’s book about when doctors refuse to believe evidence. I have just become aware of another example. The evidence for diagnosing urinary tract infection (UTI) by the

Is Magnesium the Underlying Cause and Treatment for Everything?

Carolyn Dean believes magnesium deficiency is the cause of a great many diseases and recommends that everyone take magnesium supplements, preferably the one she sells, ReMag. I remain skeptical. This is magnesium. Do you need more of it? I was recently asked about the book The Magnesium Miracle, by Carolyn Dean. The word “miracle” in the

Don’t Believe What You Think

A new book by Edzard Ernst provides a concise course in critical thinking as well as a wealth of good science-based information to counter the widespread misinformation about SCAM. Edzard Ernst was once a practitioner of alternative medicine. As the world’s first professor of complementary medicine (at the University of Exeter, UK) he led a

Prenatal Screening Tests for Chromosome Abnormalities

Science has made remarkable advances in prenatal screening, but false positives and false negative results can occur, and there are ethical concerns.Having a baby used to be like opening a surprise package. You didn’t know anything about the baby until it was born. The obstetrician or midwife would announce “It’s a boy” or “It’s a

A Test For Earlier Diagnosis Of Autism? Not Convincing

Autism is diagnosed on clinical grounds by observing the child’s behavior. There is no blood test or any other objective test to diagnose it. But that hasn’t stopped people from claiming to have found one. Among other candidates, a saliva test has been proposed, and now an eye scan. In summer 2019, a press release from Flinders University reported

Skin pH: Salesmanship, Not Science

People are being encouraged to worry about the pH of their skin and to try to change it. These concerns and interventions are not supported by scientific evidence. You have probably heard of the alkaline diet. Public knowledge of pH, the scale by which acids and bases are measured, is plagued by misinformation. People who
