Not Treating – A Neglected Option
One of the criticisms of modern medicine is that doctors prescribe too many pills. That’s true. Patients and doctors sometimes get caught up in a mutual misunderstanding. The patient assumes that he needs a prescription, and the doctor assumes that the patient wants a prescription. But sometimes patients don’t either need or want a prescription. I’ll use myself as an illustration. I...
Why the latest Geier & Geier paper is not evidence that mercury in vaccines causes autism
Several people have been sending me either links to this paper or even the paper itself: Young HA, Geier DA, Geier MR. (2008). Thimerosal exposure in infants and neurodevelopmental disorders: An assessment of computerized medical records in the Vaccine Safety Datalink. J Neurol Sci. 2008 May 14 [Epub ahead of print]. (Full text here.) A few have asked me whether I was...
The media versus the frontiers of medicine and surgery
A couple of months ago, one of my esteemed co-bloggers, Wally Sampson, wrote an excellent article about borderlines in research in conventional medicine. Such borderlines are particularly common in my area of expertise (cancer, which is also Dr. Sampson’s area of expertise) because there are so many cancers for which we do not as yet have reliably curative therapies. Patients faced with...
Forks in the road
It’s been decades since the onslaught of organized quackery began against science and reason. Although most physicians are still capable of reasoning, the percentage of medical graduates whose brains have been cleansed of that ability seems to have increased. Either the brains have been cleansed or they have learned to coexist with unreason and to use both functions simultaneously. The latter is...

The Media and “CAM”
Recently I have been generally critical of how mainstream media deals with scientific topics. Science is often complex and requires hard work and diligence on the part of a journalist to get the story right. In recent years mainstream news outlets have been downsizing or eliminating their science journalists and tasking general reporters and editors to handle science stories. Meanwhile, as science...
Connections
I have a friend who’s an artist and he’s some times taken a view which I don’t agree with very well. He’ll hold up a flower and say, “look how beautiful it is,” and I’ll agree, I think. And he says, “you see, I as an artist can see how beautiful this is, but you as a scientist, oh, take this all...
Stem Cell Therapy and the Need for Transparency
Dr. Geeta Shroff is an Indian physician who is running a New Delhi clinic offering embryonic stem cell therapies for a large number of various medical conditions. The only thing these medical conditions have in common is that they are incurable. Indian law allows for the use of unproven treatments for terminal or incurable diseases. I cannot know Dr. Shroff’s intentions, but...
Diagnostic Dilemmas
Sometimes diagnosis is straightforward. If a woman has missed several periods and has a big belly with a fetal heartbeat, it’s pretty easy to diagnose pregnancy. But most of the time diagnosis is much more difficult. Alzheimer’s can’t be diagnosed for sure until the patient dies and you do an autopsy. If only we had one of those Star Trek gadgets to...
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...
The TACT is at least as Bad as We Predicted
I had wanted to follow Dr. Sampson’s discussion of “Healing Touch” with one of my own, because I had an interesting experience with one of its proponents years ago, and I’ll do that soon. I had also wanted to begin a series of posts about acupuncture, which I’ll also do eventually. Just yesterday, however, Liz Woeckner, co-author of our recently published critique of...
