High dose vitamin C and cancer: Has Linus Pauling been vindicated?

Treating cancer with high-doses of vitamin C is a zombie idea that began with Linus Pauling, and has failed to die ever since. But has new research vindicated this idea? No. No in any meaningful way. This work is the very definition of a long run for a short slide.

Can Psychosis be Prevented?

I recently read an article in Discover magazine entitled “Stop the Madness.” It was about a new treatment program that allegedly can prevent schizophrenia and other forms of psychosis. I found it very disturbing. The PIER (Portland Identification and Early Referral) program was founded by a psychiatrist, Dr. William McFarlane, in Portland, Maine. It has recently expanded to 4 other US sites...

Are Cardiologists Ordering Too Many CT Angiograms?

A really snazzy new invention allows doctors to see inside their patients’ hearts as never before: the CT angiogram. It produces gorgeous 3-D video images of the beating heart in action. It allows us to see the blood flow through the heart’s chambers and it shows any plaque in the coronary arteries. Cardiologists are understandably excited about this new tool. Too excited....

Another State Promotes the Pseudoscientific Cult that is “Naturopathic Medicine.” Part 1

Minnesota has recently become the 15th state in the U.S. to formally endorse the claims of a tiny group of naturopaths who portray themselves as physicians.* The bill , like the popular-media “CAM” reports that Steve Novella criticized on Wednesday, merely parrots what these naturopaths claim about themselves. It reveals no attempt to investigate or to judge the tenets of the field. The following excerpts present...

Jenny McCarthy, Jim Carrey, and “Green Our Vaccines”: Anti-vaccine, not “pro-safe vaccine”

Last week, there was a rally in Washington, D.C. How many people actually attended the rally is uncertain. The organizers themselves claim that 8,500 people attended, while more objective estimates from people not associated with the march put the number at probably less than 1,000. Of course, such wide variations in estimates for the attendance at such events are not uncommon. For...

Early detection of cancer, part 2: Breast cancer and MRI

Note: If you haven’t already, you should read PART 1 of this two-part series. It defines several terms that I will be using in this post, and I don’t plan on explaining them again, given that they were explained in detail in Part 1. Of course, if you’re a medical professional and already know what lead time bias, length bias, and stage...

Monkey business in autism research

NOTE: I had originally planned on posting Part II of a series on cancer screening. However, something came up on Friday that, in my estimation, requires a timely response. I should also inform readers that, because next Monday is a holiday here in the U.S., I haven’t yet decided whether I will be doing a post next week or not. Stay tuned...

The early detection of cancer and improved survival: More complicated than most people think

“Early detection of cancer saves lives.” How many times have you heard this statement or something resembling it? It’s a common assumption (indeed, a seemingly common sense assumption) that detecting cancer early is always a good thing. Why wouldn’t it always be a good thing, after all? For many cancers, such as breast cancer and colon cancer, there’s little doubt tha early...

The Ethics of “CAM” Trials: Gonzo (Part I)

Blogger’s note: This blog, which is rough going in places, will be presented in either 2 or 3 parts (I won’t know which until next week). I’ll post a part each week until it is complete, but due to overwhelming popular demand I promise to maintain the every-other-week posting of the far more amusing Weekly Waluation of the Weasel Words of Woo/2. Introduction On Feb. 25,...

Thoughts on Neuroplasticity

I recently read a fascinating book, The Brain That Changes Itself by Norman Doidge. He describes case histories and research indicating that the brain is far more malleable than we once thought. We used to think each function was localized to a small area of the brain and if you lost that area of brain tissue the function was gone forever. We once thought...
