TB Or Not TB? Don’t Rely on a Blood Test

TB can’t be diagnosed with a blood test. Tuberculosis has been infecting humans since prehistoric times. It’s still with us. It usually can be cured today with good medical care but is still a serious problem in much of the world, especially among underprivileged socioeconomic groups and some ethnic populations. It kills 1.5 million people

The Role of Liquid Biopsies in Oncology

Liquid biopsies can be used to reduce the amount of chemotherapy used for patients with stage II colon cancer. When a patient has cancer, cell-free tumor DNA circulates in the blood and can be detected in a peripheral blood sample. This is known as a “liquid biopsy,” and it has become a routine practice in

Medical Tests to Avoid

When I first started looking into chiropractic, I read about one of their continuing medical education (CME) offerings. CME for physicians is intended to update their knowledge so they can treat patients more effectively.  This chiropractic CME course didn’t try to inform chiropractors about new knowledge from recent studies (there isn’t much new chiropractic research),

Living with Uncertainty

Uncertainty is uncomfortable. It is only natural to want certainty. It is more comfortable to be certain and wrong than to be uncertain. Like anyone else, I would like to be comfortable, but I think truth matters. I’d rather be uncertain than wrong; wouldn’t you?  As Voltaire said, “Uncertainty is an uncomfortable position. But certainty

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
