Some 22 multi-drug-resistant and extreme-drug-resistant TB patients in a South African hospital went on a rampage Wednesday to protest prison-like conditions.

The Jose Pearson TB hospital in Port Elizabeth has beefed up its security measures after the patients, 17 men and five women aged between 18 and 42, were arrested for throwing rocks at security guards and vandalising equipment. The patients were currently housed in an isolated facility in the hospital after they were returned by court and police on Thursday for fears of their highly infectious diseases

The number of HIV cases among young gay men has increased in a big way, the Centers for Disease Control (CDC) reported Thursday. The CDC stated that from 2001 to 2006, the largest transmission category for HIV in the U.S. was in men who had sex with men.

Gay boys and men aged between 13 and 24-years old saw the biggest increase in HIV cases, about 10 times higher than in the homosexual community overall, where the number of new infections is going up about 1.5 percent a year. homosexual men were the only risk group in which the number of new infections rose annually from 2001 through 2006

A hand-held trans-cranial magnetic stimulation device could be helpful in treatment of most severe migrane attacks, researchers say. When held against the back of the head and turned on, the device delivers two quick magnetic pulses into the brain, which scientists believe short-circuit the electrical storm.

Invented by Medtronic, the device was tested in a trial of 61 patients who experienced on average 15 or more headache days in a month and whose condition did not respond to conventional medicine for three months. The device is put up against the back of the head, and users push a button to administer the magnetic pulse

Children born to mothers who are depressed during pregnancy are likely to develop more slowly than their peers, new research shows.
