Do doctors pay attention to negative randomized clinical trials?
We at the Science-Based Medicine blog believe that all medicine, regardless of where it comes from, should be held to a single science-based standard with regards to efficacy, effectiveness, and safety. We tend to focus primarily on “complementary and alternative medicine” (CAM), now more commonly known as “integrative medicine,” because (1) we believe it to be undermining the scientific basis of medicine...
Point-of-Care Ultrasound: The Best Thing Since Stethoscopes?
A bit of good news for a change: a “Perspective” article in the New England Journal of Medicine describes how point-of-care ultrasound devices are being integrated into medical education. The wonders of modern medical technology are akin to science fiction. We don’t yet have a tricorder like “Bones” McCoy uses on Star Trek, but we are heading in that direction, and the...
E-cigarettes: The growing popularity of an unregulated drug delivery device
This post is not about vaccines (for a change). However, I deem it appropriate to mention that one of the topics that I blog most frequently about is vaccines and how the antivaccine movement pushes pseudoscience and quackery based on its apparently implacable hatred of vaccines. (You’ll see why very shortly.) It seems almost as long as my interest in the topic...
Will Your Smartphone Become a Tricorder?
The Star Trek universe is a fairly optimistic vision of the future. It’s what we would like it to be – an adventure fueled by advanced technology. In the world of Star Trek technology makes life better and causes few problems. One of the most iconic examples of Star Trek technology is the medical tricorder. What doctor has not fantasized about walking...
Bogus Electrodermal Testing Devices and the Failure of Regulators to Act
Electrodermal testing is a bogus procedure where measurements of skin conductance with a biofeedback device are entered into a computer to diagnose nonexistent health problems and “energy imbalances” and to recommend treatments for them, often involving the sale of homeopathic remedies and other useless products. It falls under the general category of EAV (Electro Acupuncture of Voll). The history and variants of...
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 FDA for the Average SBM Consumer
How the Food and Drug Administration came to be is a story that is filled with death, intrigue and dubious characters. It also, like most stories, has its share of heroes and vindications. The list of those who have died to bring us the agency we know today is long, but even today, the death-toll continues. Now this is not the horrible...
Biofeedback and Laser for Allergies
AllergiCare Relief Centers are a chain of franchises started by a man called David Tucker who is not listed as having an MD or any other title. They offer diagnosis of allergies by biofeedback and treatment of allergies by laser acupuncture. They admit that the method is not backed by any science, and they claim that what they are doing is not...
FDA approval of drugs and transparency in clinical trial results
Note: The reason that I am posting today rather than my usual Monday slot is because the article I discuss here was embargoed until last night. Consequently, I asked Harriet if she would trade days with me this week, and she was kind enough to do so. One thing that science relies on almost absolutely is transparency. Because one of the most...
Recognizing Dubious Health Devices
The public is often left to fend for themselves in the marketplace of medical devices and health aids. Current regulations in most countries are inadequate to prevent grossly misleading claims in advertising and to provide adequate evidence for safety and effectiveness for products on the market. So it is helpful for consumers to be aware of the red flags for dubious devices...
