An experiment in paying through the nose for “unnecessary care”

Rats. Harriet stole what was going to be the title of this post! This is going to be something completely different than what I usually write about. Well, maybe not completely different, but different from the vast majority of my posts. As Dr. Snyder noted on Friday, it’s easy to find new woo-filled claims or dangerous, evidence-lacking trends to write about. Heck,...

“Low T”: The triumph of marketing over science

A man on TV is selling me a miracle cure that will keep me young forever. It’s called Androgel…for treating something called Low T, a pharmaceutical company–recognized condition affecting millions of men with low testosterone, previously known as getting older. —The Colbert Report, December 2012   And now for something completely different…sort of. After writing so much about the latest developments in...

Colonoscopy and Other Colorectal Cancer Screening Options: An Update

When I wrote about colonoscopy in 2010, colonoscopy was thought to be the best screening test for colorectal cancer because it could visualize the entire colon and could remove adenomas that were precursors of cancer. But only fecal occult blood testing (FOBT) and sigmoidoscopy had been proven to decrease colorectal cancer incidence and mortality (by 16% and 28%, respectively). Observational evidence suggested...

Redefining cancer

Blogging is a rather immediate endeavor. Over the last nine years (nearly), I’ve lost track of how many times I saw something that I wanted to blog about but by the time I got around to it, it was no longer topical. Usually what happens is that my Dug the Dog tendencies take over, as I’m distracted by yet another squirrel, although...

Baby’s DNA in Mom’s Blood: Noninvasive Prenatal Testing

Until recently, the moment of birth was a surprise. We anxiously awaited the obstetrician’s announcement: “It’s a boy!” or “It’s a girl!” Then we checked to see if any crucial parts were missing and we counted the fingers and toes. We had to wait for a baby to be born before we could know its sex and whether it was normal. Today,...

Does Everybody Have Chronic Lyme Disease? Does Anyone?

A deplorable article by Suzy Cohen on Huffington Post is titled “Feel Bad? It Could Be Lyme Unless Proven Otherwise.” It consists of irresponsible fear-mongering about a nonexistent disease. A science-based article would be titled “Feel Bad? It Couldn’t Be Chronic Lyme Disease Because CLD Is Nonexistent Until Proven Otherwise.” Cohen says: People often attribute uncomfortable symptoms to aging, stress, or the...

“Postnatal depression blood test breakthrough” or Churnalism?

“Postnatal depression blood test breakthrough” proclaimed the headline. The UK Guardian article then declared: British doctors reveal ‘extremely important’ research that could help tens of thousands of women at risk. Here it comes. Readers were going to be fed a press release generated by the study’s authors and forwarded undigested by the media but disguised as writings of a journalist.  If only...

The difference between science-based medicine and CAM

There is a huge difference between science-based medicine (SBM) and so-called "complementary and alternative medicine" (CAM) or, as it's increasingly called, "integrative medicine." That difference is that SBM changes with new science. The change might be messier and slower than we would like, but eventually science and evidence win out.

A Skeptical Look at Screening Tests

I’m going to follow Mark Crislip’s example and recycle my presentation from The Amazing Meeting last week, not because I’m lazy or short on time (although I am both), but because I think the information is worth sharing with a larger audience. We’ve all had screening tests and we’re all likely to have more of them, but there is a lot of...

Meet Your Microbes: uBiome Offers New Service

We are not alone. Walt Whitman didn’t know how right he was when he said, “I contain multitudes.” The microbes on and in our bodies outnumber our own cells 10:1.  Perhaps that creeps you out. Perhaps that makes you curious to know just who all these billions of creatures are that are using your body for a home and a transportation device....
