Striking a Nerve: Docs Flunk Diagnostics Math

A study in JAMA Internal Medicine suggesting that most newly-minted MDs, and a sizeable chunk of more experienced physicians, don't understand how "positive predictive value" (PPV) works.  It's a commonplace that medical tests are over-prescribed -- many are diagnostic procedures said to be of limited value.  The study by Jain and colleagues points to another explanation -- many doctors may simply fail to understand how uninformative the test results really are, at least when it comes to low-prevalence conditions.

Blood of World's Oldest Woman Hints at Limits of Life

Death is the one certainty in life – a pioneering analysis of blood from one of the world's oldest and healthiest women has given clues to why it happens.

Born in 1890, Hendrikje van Andel-Schipper was at one point the oldest woman in the world. She was also remarkable for her health, with crystal-clear cognition until she was close to death, and a blood circulatory system free of disease. When she died in 2005, she bequeathed her body to science, with the full support of her living relatives that any outcomes of scientific analysis – as well as her name – be made public.

Researchers have now examined her blood and other tissues to see how they were affected by age.

Research: Stroke

I hope and pray that no one has had a patient go through this.  A short story I had a guy a few years ago who came in complaining of headaches and neck pain for about two weeks.  I did an exam, x-ray, and put him on muscle stim.  While he was on muscle stim he commented to me that it really bothered him at night and he would wake up in a cold sweat.  Night sweats and back or neck pain do not bode well so I referred him to his family physician and told him something was going on.  Well an MRI later demonstrated a aneurysm in the circle of Willis.  He had surgery and did fine the MD said that I saved his life.  
 
The negative press on stroke is mostly about vertebral artery dissections.   These are extremely rare events and are much less common than a carotid artery dissection.   What happens in a vertebral artery dissection (VAD) is that there is a tear in the wall of the artery and a blood clot forms, or due to a tear there is lack of blood supply to the brain.  This can lead to a stroke.  Now two-thirds of these are spontaneous with no known cause and one-third are traumatic (auto accidents, direct blows to the neck, or strangulation, manipulation is also placed here).  I believe that VAD is one of the leading causes of stroke in people under 40 years of age.  We know the devastation that this can cause if it does occur.
 
But it is difficult to study these events because they are so rare.  Researchers could follow thousands of patients for a number of years and never come across a VAD.

Computer Ergonomics for Children
Sunday, April 27, 2014 11:33 PM

At least 70 percent of America's 30 million elementary school students use computers and as a result, doctors of chiropractic are treating more young patients suffering from the effects of working at computer stations that are either designed for adults or poorly designed for children. If children and adults in your home share the same computer workstation, make certain that the workstation can be modified for each person's use. Specifically, for children:
