Chronic Fatigue Syndrome and Retroviruses: Jumping the Gun

When I first heard that a retrovirus had been identified as a possible cause of chronic fatigue syndrome, I withheld judgment and awaited further developments. When I heard that two subsequent studies had failed to replicate the findings of the first, I assumed that the first had been a false alarm and would be disregarded. Not so.  It’s a classic case of...

Autism Onset and the Vaccine Schedule – Revisited

This week on Science-Based Medicine I wrote an article about a new study looking at the onset of autism symptoms, showing that most children who will later be diagnosed with autism will show clear signs of autism at 12 months of age, but not 6 months. This is an interesting study that sheds light on the natural course of autism. I also...

The Early Course of Autism

Understanding the natural history of a disease is an important framework to have. It not only is critical for prognosis, but also informs us about diagnostic and screening strategies, is important to assessing interventions, and provides clues to causation. There has been much debate about the early course of autism, specifically the earliest age at which autism may be detected. At present...

Questioning Colonoscopy

Everybody knows that colonoscopy is the best test to screen for colorectal cancer and that colonoscopies save lives. Everybody may be wrong. Colonoscopy is increasingly viewed as the gold standard for colorectal cancer screening, but its reputation is not based on solid evidence. In reality,  it is not yet known for certain whether colonoscopy can help reduce the number of deaths from...

Yes, Jacqueline: EBM ought to be Synonymous with SBM

“Ridiculing RCTs and EBM” Last week Val Jones posted a short piece on her BetterHealth blog in which she expressed her appreciation for a well-known spoof that had appeared in the British Medical Journal (BMJ) in 2003: Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomised controlled trials Dr. Val included the spoof’s abstract in her...

Study shows antidepressants useless for mild to moderate depression? Not exactly.

As Harriet Hall has written, psychiatry bashing is a popular media sport. There seems to be a bias against treatment of psychiatric disabilities, and a common claim is that antidepressants are no better than placebo. The New York Times illustrated both the perpetuation of the myth that antidepressants are ineffective, and the increasing and disturbing tendency of major media organizations to confuse...

The Lancet retracts Andrew Wakefield’s article

In 1998 Andrew Wakefield and 11 other co-authors published a study with the unremarkable title: Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children. Such a title would hardly grab a science journalist’s attention, but the small study sparked widespread hysteria about a possible connection between the mumps-measles-rubella (MMR) vaccine and autism spectrum disorder (ASD). The study itself has not stood...

The Tamiflu Spin

I will start, for those of you who are new to the blog, with two disclaimers. First, I am an infectious disease doctor. It is a simple job: Me find bug. Me kill bug. Me go home. I spend all day taking care of patients with infections. My income comes from treating and preventing infections. So I must have some sort of...

Reflexive doubt

Those of us who study, practice and write about medicine cherish the hope that explaining the science behind medicine (or the lack of science behind “alternative” treatments) will promote a better understanding of medicine. Certainly, I would not bother to write about medical topics if I did not believe that promoting science based medicine would lead to increased understanding of medical recommendations...

The Mythology of Larry Dossey

A “Double Standard”? Last week I had planned to write a comprehensive critique of a recent comment by Larry Dossey. He had posted it on Val Jones’s betterhealth website in response to Dr. Val’s essay, “The Decade’s Top 5 Threats To Science In Medicine,” originally posted here on SBM. Much of what Dr. Val had identified as the top threats involved recent...
