As hospitals elbow one another to attract patients, increasingly they're hoping to tap into Americans' interest in — and willingness to spend money on — complementary and alternative therapies such as acupuncture and massage.

THREE DOZEN doctors-in-training recently sat in a conference room in Tucson. Arizona sunshine streamed through open French windows. On the floor were votive candles and peacock feathers, symbols of healing. It was the closing ceremony in a month-long course at the Centre for Integrative Medicine at the University of Arizona, promoting the notion that doctors should use alternative treatments alongside conventional ones. Speaking to the students was Andrew Weil, a doctor and campaigner who heads the centre.

Dave deBronkart visited his doctor’s office in 2006 with nagging shoulder pain. A subsequent X-ray showed that his shoulder would heal, but incidentally also revealed a shadow on his lung, turning what deBronkart expected to be a routine visit into diagnosis of a rare form of kidney cancer.

Why do rich nations elect to fund global health campaigns to tackle problems with no supra-national element at all, such as obesity or smoking?

"To be blunt, if my wife and I didn't think it was helping him, we wouldn't have continued with it," says Dan Polley. He's talking about Mikey, the Polleys' 2½-year-old in the next room, who was diagnosed with acute lymphocytic leukemia when he was 6 months old. Chemotherapy, radiation, and a bone marrow transplant have been crucial elements of Mikey's treatment. But the "it" his father speaks of is nothing like these aggressive, costly, and heavily researched exemplars of western care—it is a kind of touch therapy, from the camp of alternative medicine.

The numbers of and roles assumed by NPs and PAs have been growing steadily, and allowing these providers to take on an even greater role could address the increased demand for primary care.

Eric Dishman is used to thinking about how technology can transform the world of health care. As an Intel Fellow and general manager of the company’s Health Strategy & Solutions Group, his job is all about finding innovative new approaches to healthcare. Eric Dishman: Take health care off the mainframe And he’s no stranger to talking about them. At TEDMED 2009, in the talk featured to the left, Dishman asked us to “Take health care off the mainframe,” boldly comparing the current American health care system to mainframe computers circa 1959.

Some Viral Hemorrhagic Fever causing agents like Lassa fever, Rift Valley fever, Marburg virus, Ebola virus and Bolivian hemorrhagic fever are highly contagious and deadly diseases, with the theoretical potential to become pandemics. Their ability to spread efficiently enough to cause a pandemic is limited, however, as transmission of these viruses requires close contact with the infected vector, and the vector only has a short time before death or serious illness. Furthermore, the short time between a vector becoming infectious and the onset of symptoms allows medical professionals to quickly quarantine vectors, and prevent them from carrying the pathogen elsewhere. Genetic mutations could occur, which could elevate their potential for causing widespread harm; thus close observation by contagious disease specialists is merited.
