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...

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...

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...

Mercury emissions from coal-burning power plants and autism: Is there a correlation?

On April 30, outside the courthouse in Dallas, a press conference/rally was held. This particular rally was in response to a new study published by a group led by Dr. Raymond F. Palmer in the Department of Family and Community Medicine at the University of Texas Health Science Center in San Antonio, whose conclusion was that autism prevalence correlates strongly with proximity...

The North Carolina Board of Medical Examiners, Dr. Rashid Buttar, and protecting the public from practitioners of non-science-based medicine

One of the most contentious and difficult aspects of trying to improve medical care in this country is enforcing a minimal “standard of care.” Optimally, this standard of care should be based on science- and evidence-based medicine and act swiftly when a practitioner practices medicine that doesn’t meet even a minimal requirement for scientific studies and clinical trials to support it. At...

Barriers to practicing science-based surgery

Much to the relief of regular readers, I will now change topics from those of the last two weeks. Although fun and amusing (except to those who fall for them), continuing with such material for too long risks sending this blog too far in a direction that no one would want. So, instead, this week it’s time to get serious again. A...

Would you like a liver flush with that colon cleanse?

I have to apologize for last week’s post. I’m not apologizing for the subject matter (the obsession that reigns supreme among some alt-med aficionados over “cleansing” their colons to “purge toxins” and achieve the super-regularity of several bowel movements a day). Rather, I’m sorry I probably didn’t emphasize quite strongly enough just how disgusting one of the links that I included was....

Colon “cleanses”: A load of you know what…

One of the more popular treatments in alternative medicine is the "colon cleanse," a treatment based on the idea that there is 20 lbs. worth of accumulated feces in your colon that is slowly poisoning you. There's only one way to put it. Colon cleansing is a load of crap.
