The US Preventive Services Task Force (USPSTF) recommends that everyone aged 50-75 be screened for colon cancer with any one of three options: colonoscopy every 10 years, flexible sigmoidoscopy every 5 years, or fecal occult blood testing (FOBT) every year. Conventional colonoscopy is considered the “gold standard” since it allows for direct detection and biopsy
Acupuncture has been in the news recently. A former President of South Korea had to undergo major surgery to remove an acupuncture needle that had somehow lodged in his lung. A recent study in Pain compiled a list of 95 published reports of serious complications of acupuncture including 5 deaths. Meanwhile, acupuncturists continue to insist that
It has just been announced, in the July/August issue of Skeptical Inquirer magazine, that our own Steven Novella has been awarded the 2010 Robert P. Balles Annual Prize in Critical Thinking. It will be formally presented at the CSIcon conference in New Orleans on October 28, 2011. The Prize is a $1500 award given to the author of the
Science has found no evidence that vaccines cause autism; but the true cause(s) of autism have not yet been determined. So far the available evidence has pointed towards a largely genetic cause with possible interaction with environmental factors. A new study supports that interpretation. It also supports previous evidence that autism is triggered prior to
A common question of skeptics and science-based thinkers is “How could anyone believe that?” People do believe some really weird things and even some obviously false things. The more basic question is how we form all our beliefs, whether false or true. Michael Shermer’s book Why People Believe Weird Things has become a classic. Now
People tend to limit their reading to sources that agree with their beliefs. We find ourselves mostly preaching to the choir; our message usually doesn’t reach those who most need to hear it. I recently received an inquiry from a science-based medical doctor asking how to approach others in building a bridge to clarify so
Explanatory studies are done under controlled conditions to determine whether a treatment has any efficacy compared to a placebo. Pragmatic studies are designed to assess how the intervention performs in everyday real world practice. Pragmatic studies measure practical success but don’t determine actual efficacy: that requires a proper randomized controlled trial (RCT) with an appropriate
In my recent review of Peter Palmieri’s book Suffer the Children I said I would later try to cover some of the many other important issues he brings up. One of the themes in the book is the process of critical thinking and the various cognitive traps doctors fall into. I will address some of
A friend asked me to look at the evidence for hash oil as a treatment for glioma. His teenage daughter was recently diagnosed with brain cancer: a grade 3 anaplastic ependymoma. It recurred very rapidly after surgery and radiotherapy and the latest tissue diagnosis shows an aggressive grade IV glioma. Her prognosis is not good.
When an article is published in a medical journal, the authors must disclose any conflicts of interest. This is important, because even if they think owning stock in the drug company won’t influence their scientific judgment, we know that subtle biases can creep in to somehow affect the findings of studies. It has been shown
