Drug Resistant TB

Drug Resistant TB - At least a dozen people in India are infected with a type of tuberculosis that is resistant to all antibiotics used to treat the disease. In December, the journal Clinical Infectious Diseases published an online report that documented four of the cases. This weekend, news outlets in India reported that there were actually at least 12 people with the drug-resistant lung disease. Officials fear that what they've seen so far is just the beginning, and that many more cases are lurking undetected. "It's estimated that on average, a tuberculosis patient infects 10 to 20 contacts in a year, and there's no reason to suspect that this strain is any less transmissible," study co-author Zarir Udwadia of the Hinduja National Hospital and Medical Research Centre in Mumbai told New Scientist. "Short of quarantining them in hospitals with isolation facilities till they become non-infectious – which is not practical or possible – there is nothing else one can do to prevent transmission." Patients with TB must take antibiotics for a long time to cure the disease. Many don't get the right medications, or don't take their medications properly, which allows the evolution of drug-resistant strains. Over time, TB-causing bacteria have become resistant to more and more types of antibiotics -- and, now, apparently, all antibiotics. This is not the first outbreak of totally drug resistant TB. According to the New Scientist report, in 2007, two patients were identified with the disease in Italy; in 2009, 15 patients were identified with the disease in Iran. Drug Resistant TB

Man Hits Teen on Plane Over iPhone

Man Hits Teen on Plane Over iPhone - Police say a man on a Southwest Airlines flight from Las Vegas punched a teenager who refused to turn off his iPhone as the plane approached the Boise airport. Officers arrested 68-year-old Russell E. Miller, of Boise, on suspicion of misdemeanor battery Tuesday. He has been released from jail on bond. Witnesses told police the 15-year-old was playing games and listening to music on his cell phone when flight attendants instructed passengers to turn off their electronic devices because the plane was landing. Witnesses told police that when the teen didn't respond, Miller got angry and punched the boy in the arm. Miller says he "tapped" the teen on the shoulder after he refused to turn off the phone. He told the Idaho Statesman that he may have "overreacted," but that he did not punch the teen. Man Hits Teen on Plane Over iPhone

Interac’s first two Flash issuers are Scotiabank and RBC Royal Bank, which will roll out their first contactless cards next summer.
