What Is Shingles? What Causes Shingles?
Shingles is caused by the herpes varicella-zoster (or simply zoster) virus. This virus also causes chickenpox. Most of us get chickenpox during childhood, but after we recover the virus remains inactive (dormant) in our nervous system. Our immune system stops the virus from becoming active. However, later in life it may become reactivated, causing shingles. Shingles is an infection of a nerve and the area of skin around it.

Global Poverty Eradication Efforts Should Start With Health Issues, Opinion Piece Says
"Eradicating global poverty starts with the health of the world"s poor," Bill Frist, former U.S. Senate Majority leader and currently a member of the Millennium Challenge Corporation"s (MCC) Board of Directors, writes in a Charlotte Observer opinion piece. "It starts with empowering them physically to contribute to the vitality of their countries," Frist says, which "makes as much good sense for the world"s poor as for our collective international economic growth."Frist says that Obama"s recent proposal of a six-year $63 billion global health initiative is "bold," and the "smart use of res improves the health of the world"s poorest and strengthens the global economic climate for us all." He writes that it"s important not to overlook "other factors that directly affect global health," such as roads and water and sanitation systems. He points to the U.S. government"s Millennium Challenge Corporation, which "takes a holistic approach to global health, laying the groundwork for poverty reduction and economic development.""By building healthier, hopeful, and productive communities, we build safer and more secure societies that can alleviate global poverty and contribute to global prosperity," Frist writes. "When communities are productive and thriving they don"t become breeding grounds for dangerous extremism" (Frist, Charlotte Observer, 5/14).

Med Schools Improve Conflict Of Interest Policies, But Widespread Problems Remain

According to the latest ratings of two watchdog groups, medical schools are "improving their conflict-of-interest policies to police their ties with drug and medical-device makers. But more than half the schools still have inadequate policies or no policies at all," the Wall Street Journal"s Health Blog reports. The American Medical Student Association and the Pew Prescription Project said the number of schools earning top marks had more than doubled, in part because of pressure from lawmakers like Sen. Charles Grassley, R-Iowa. But, "there are a lot of schools that are yet to look seriously at these issues," the director of the Pew project said. Grassley, meanwhile, "has demanded more information about the financial health of UC San Francisco"s medical school, raising questions about whether the entire University of California system may be mismanaging federal research funds," the Los Angeles Times reports. The school is in the midst of a law suit with former FDA administrator David Kessler, who alleged that the school had misused hundreds of millions of dollars in federal funds before he was fired for what university officials called "performance" problems. Grassley requested details of federal funds UCSF has received over five years from the National Institutes of Health, the National Science Foundation, the Department of Energy and the Department of Defense in an April letter (Oliphant, 6/17).
