Molecular breast imaging (MBI): A promising technology oversold in a TED Talk?
Occasionally, there are topics that our readers want — nay, demand — that I cover. This next topic, it turns out, is one of them. It’s a link to a TED Talk. I’m guessing that most of our readers have either viewed (or at least heard of) TED talks. Typically, they are 20-minute talks, with few or no slides, by various experts...
The Meaning of Secondary Prevention
A November letter to the editor in American Family Physician chastises that publication for misusing the term “secondary prevention,” even using it in the title of an article that was actually about tertiary prevention. I am guilty of the same sin. I had been influenced by simplistic explanations that distinguished only two kinds of prevention: primary and secondary. I thought primary prevention...
Followup: More Evidence against the XMRV Virus as a Cause of Chronic Fatigue Syndrome
A mouse leukemia retrovirus, xenotropic murine leukemia virus-related virus (XMRV retrovirus), has been under consideration as a possible cause of chronic fatigue syndrome (CFS, and also prostate cancer). In a study published in Science in October 2009, Lombardi et al. found XMRV in 67% of CFS patients and 3.7% of controls. Several subsequent studies in the UK, the Netherlands, and the US...
New Recommendations for Calcium and Vitamin D Intake
A Walmart ad in my local newspaper trumpets “75% of all Americans don’t get enough Vitamin D” and offers to sell me Maximum Strength Vitamin D3, 5000 IU capsules to “promote bone, colon and breast health.” Meanwhile, the Institute of Medicine (IOM) tells me that “the majority of Americans and Canadians are receiving adequate amounts of … vitamin D” and that no...
Integrating patient experience into research and clinical medicine: Towards true “personalized medicine”
We advocate science-based medicine (SBM) on this blog. However, from time to time, I feel it necessary to point out that science-based medicine is not the same thing as turning medicine into a science. Rather, we argue that what we do as clinicians should be based in science. This is not a distinction without a difference. If we were practicing pure science,...
Mike Adams on Dr. Mehmet Oz’s colon polyps: “Spontaneous” disease?
Given that it’s a holiday and I debated whether or not I even wanted to post anything today, I think I’ll keep things light and uncharacteristically brief today. After all, not every post can be like last week’s epic on Avastin or the week before’s epic on peer review. That’s a lot of work, and it is a holiday, after all. Besides,...
The genetics of autism
Autism and autism spectrum disorders (ASDs) actually represent a rather large continuum of conditions that range from very severe neurodevelopmental delay and abnormalities to the relatively mild. In severe cases, the child is nonverbal and displays a fairly well-characterized set of behaviors, including repetitive behaviors such as “stimming” (for example, hand flapping, making sounds, head rolling, and body rocking.), restricted behavior and...
Certainty versus knowledge in medicine
I don’t want knowledge. I want certainty! — David Bowie, from Law (Earthlings on Fire) If there’s a trait among humans that seems universal, it appears to be an unquenchable thirst for certainty. It is likely to be a major force that drives people into the arms of religion, even radical religions that have clearly irrational views, such as the idea that...
CAM on campus: Ethics
In a previous post I described a lecture given by a faculty member to first-year medical students on my campus introducing us to integrative medicine (IM). Here I describe his lecture to the second-year class on legal and ethical aspects of complementary and alternative medicine (CAM). Dr. P began his lecture by describing CAM using the now-familiar NCCAM classification. He gave the...
The Mammogram Post-Mortem
The Mammogram Post Mortem Steve Novella whimsically opined on a recent phone call that irrationality must convey a survival advantage for humans. I’m afraid he has a point. It’s much easier to scare people than to reassure them, and we have a difficult time with objectivity in the face of a good story. In fact, our brains seem to be hard wired...
