Shingles, also known as Herpes Zoster, usually occurs in elderly adults. It is characterized by painful eruption of vesicular lesions that follow a dermatomal distribution. The thoracic and lumbar roots are most commonly affected.
Pain precedes the appearance of the lesions and is severe and debilitating. The incidence and severity of herpes zoster increases with increasing age... Read more »

The physical exam is an important skill for the practitioner of palliative medical arts because we may be working with patients in their home where technical diagnostic options are limited or in a treatment mode that has been defined by avoiding further diagnostic tests. So I am particularly interested by any article that discusses clinical examination skills relevant to palliative medicine. Of course the title did not hurt in causing me to pause. "Gurgling ........

In the year AD 1098 a spruce tree was chopped down in the Chuska Mountains, which run roughly along what is now the border between Arizona and New Mexico. We don’t know who cut it down, exactly, since the people living in the area at the time had no system of writing and have therefore [...]... Read more »

This 2010/2011 winter has been brutally cold here in the Northeast, and unarguably colder than most. As time has passed over the years, it's become harder and harder to jump in the water this time of year. But, therein lies no choice if one is to continue working as a diving contractor in New England. There is nothing pleasant about it, and all you can do is plan well in advance for the elements.
For the majority of the winter months, say late November through early March, we use hotwater suits........ Read more »

Since Thorstein Veblen’s 1899 book Theory of the Leisure Class, the economics profession has taken a somewhat mixed approach to consumption. In areas such signalling theory, Veblen’s argument that conspicuous consumption must be wasteful and expensive to be a reliable signal of wealth is well recognised. Conspicuous consumption has a purpose as a signal. However, [...]... Read more »

Jurassic Park beer:
Fossil Fuels Brewing Co. makes beer with an Eocene-era yeast, formerly encased in a 45 million year old chunk of amber! Incredible, but apparently true. Viable Bacillus spores were discovered first in 25-40 million year old amber by Raul Cano (these spores are so tough you can't kill them with an autoclave). He then founded a startup (Ambergene) with the hopes of discovering ancient antibiotics (this was back during the natural ........ Read more »

Autoimmune diseases are troubling, and often frustrating and painful for health care practitioners and patients. As far as I know, celiac disease is the only autoimmune disorder with a specific and identified trigger: the protein gluten. It has also been pointed out that the incidence of Celiac Disease, the formal name for gluten-triggered autoimmune reactions in the bowel, appears to have been increasing. Some have claimed that humans are not adapted to consumption of plant proteins like glu........ Read more »

There's a lot of talk, much of it rather speculative, about "neuroethics" nowadays.But there's one all too real ethical dilemma, a direct consequence of modern neuroscience, that gets very little attention. This is the problem of incidental findings on MRI scans.An "incidental finding" is when you scan someone's brain for research purposes, and, unexpectedly, notice that something looks wrong with it. This is surprisingly common: estimates range from 2–8% of the general population. It will hap........ Read more »

Insomnia is something all of us struggle with from time to time. Not being able to get off to sleep is perhaps one of the most frustrating and loathsome things in the world (second only to an itchy back).
