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...
Christiane Northrup, MD: Science Tainted with Strange Beliefs
After her daughter left for college, Christiane Northrup, MD, went for a morning walk one day. About halfway through her walk she developed an ache in her throat radiating up into her jaw. It felt like a fist was squeezing her esophagus. It persisted even after she returned home. What would you have done? I think even the average layperson knows that...
A real “Era III Emergency Room”
Due to the holiday, I have not had time to compose the usual lengthy and analytic post that readers have come to know and (hopefully) love. However, Dr. Atwood’s Weekly Waluation of the Weasel Words of Woo #6 so perfectly brought a famous (or infamous) parody back from the depths of my memory that I had to go straight to YouTube and...
We Have to Draw the Line Somewhere
Passive acceptance of Alternative Medicine has eroded the quality of medical care in this country. With the DSHEA of 1994 and political correctness, we have lost the reverence afforded to us in times past. Our professional knowledge is called into question as our standards deteriorate. There no longer exists a line separating proven fact from speculation. There is no border separating reality...

Changing the Rules of Evidence
My daughter, Julia, loves to play games and has a bit of a competitive streak. She can make any activity into a game and is adept at making up rules on the spot. When she was younger, like most children, she had a tendency to add to or change the rules on the fly – usually to ensure a favorable outcome for...
Reading Medical Literature with a Critical Eye
A long time ago I read a study about what makes a good doctor. Some things you might think were important, like grades in medical school, were irrelevant. What correlated the best was the number of medical journals a doctor read. I don’t know whether that means good doctors read more journals or reading more journals makes a better doctor. One thing...
The “Art” of Clinical Decision-Making
Much nonsense has been written about the “art” of medicine. All too often, it amounts to a rationalization for doctors doing what they want to do instead of following the evidence. Medicine is not an art like painting. Neither is it a science like physics. It’s an applied science. Since patients are not all identical, it can be very tricky to decide...
