What is Shingles?

Shingles (herpes zoster) is an outbreak of rash or blisters on the skin that is caused by the same virus that causes chicken pox – the varicella-zoster virus.

The first sign of shingles is often burning or tingling pain, or sometimes numbness, in or under the skin. You may also feel ill with fever, chills, headache, or upset stomach.

After several days, a rash of small fluid-filled blisters, reminiscent of chickenpox, appears on reddened skin.

The pain associated with shingles can be intense and is often described as “unrelenting.”

Yellow fever (so called because one of the early symptoms of infection is jaundice) occurs only in Africa and South America. In South America sporadic infections occur almost exclusively in forestry and agricultural workers from occupational exposure in or near forests.

In Africa the virus is transmitted in three geographic regions:
principally and foremost, in the moist savanna zones of West and Central Africa during the rainy season,
secondly, outbreaks occur occasionally in urban locations and villages in Africa,
and finally, to a lesser extent, in jungle regions.

Motion sickness, a common problem in travellers by automobile, train, air, and particularly sea, usually causes mild to moderate discomfort but in severe cases can be incapacitating.

It affects up to half of children travelling in automobiles or airplanes and almost 100% of boat passengers in very rough seas.

Motion sickness is more common in women, especially during pregnancy or menstruation, children age 2-12, and in persons who have migraine headaches, but little is known about individual susceptibility.

Symptoms of motion sickness

Sensation of head position and movement is generated in the semicircular canals (angular acceleration or rotation) and otolith organs (vertical acceleration) in the inner ears and carried to the central nervous system via cranial nerve VIII.

Chemoprophylaxis is the strategy that uses medications before, during, and after the exposure period to prevent the disease caused by malaria parasites. The aim of prophylaxis is to prevent or suppress symptoms caused by blood-stage parasites.

In addition, presumptive anti-relapse therapy (also known as terminal prophylaxis) uses medications towards the end of the exposure period (or immediately thereafter) to prevent relapses or delayed-onset clinical presentations of malaria caused by hypnozoites (dormant liver stages) of P. vivax or P. ovale.

Barch named new director of Conte Center

April 22, 2008

The Silvio Conte Center for Neuroscience Research at Washington University in St. Louis has a new director. Deanna M. Barch, Ph.D., associate professor of psychology in Arts & Sciences, of psychiatry and of radiology, takes over leadership of the center from John G. Csernansky, M.D., the former Gregory B. Couch Professor of Psychiatry, who has become the chairman of psychiatry at Northwestern University.

Barch has been a close collaborator of Csernansky’s throughout the history of the Conte Center, which was established in 2001. It is one of a handful of such centers around the country created to honor former Massachusetts congressman Silvio O. Conte, a longtime advocate for scientific research. Prior to his death from cancer in 1991, Conte had sponsored the Congressional resolution that designated the 1990s as the “Decade of the Brain.”
