Europe Bans X-Ray Body Scanners

Source: AVWeb.com The European Commission decided in November to ban airport body scanning X-ray backscatter machines after studies found a small number of cancer cases linked to use of the devices. The decision affects all airports in Europe, with an exception for U.K. airports that will be allowed to test them, but not deploy them permanently. According to the European Commission, "only security scanners which do not use X-ray technology are added to the list of authorized methods for passenger screening at EU airports." The commission does approve of full non-X-ray body scanners (radio wave scanners are among those used in the U.S.) when operated under specific guidelines and restrictions. In the U.S., the TSA uses more than 250 backscatter machines at the nation's 100 busiest airports and is unmoved by Europe's position. The degree of cancer risk varies somewhat depending on the source ... as does the degree of usefulness of the machines themselves. According to the U.S. Food and Drug Administration, backscatter machines bring a cancer risk of one in 400 million. Research reported by PBS Newshour/ProPublica states that the risk of developing cancer from the machines is "anywhere from six to 100" passengers per year. In a detailed paper submitted to the White House, University of California researchers said that because backscatter X-ray energy is absorbed mainly by the skin and underlying tissue, the skin dosage may be dangerously high in localized areas. The TSA says the amount of radiation emitted by a backscatter machine is similar [...]

More ’empowered’ patients question doctors’ orders

Source: www.usatoday.com Author: Mary Brophy Marcus In the past, most patients placed their entire trust in the hands of their physician. Your doc said you needed a certain medical test, you got it. Not so much anymore. Jeff Chappell of Montgomery, Ala., recalls a visit a couple of years ago to a Charlotte emergency room, near where the family used to live, with his wife, Jacqueline, who has adrenal failure. "I blew up loud enough for everyone in the ER to hear me explain that while we were insured, an MRI was about a $1,000 co-pay," Chappell says. The couple knew her symptoms well (primarily stomach pain), knew that an MRI was not necessary under the circumstances and knew that a cortisone shot was what she needed. "The doctor walked off in a huff," Chappell says, but later came back and "compromised" by agreeing to give his wife the shot, but not before taking an abdominal X-ray to rule out other problems first. Many physicians say an increasing number of patients are getting involved in decisions about their medical care, including medication choices, whether they need a specialist, and especially whether they need expensive diagnostic tests, which some health economists say are driving up the cost of health care. 'Shared decision model' "There have been big changes," says Patrick McManus, residency director of family and community medicine at Thomas Jefferson University in Philadelphia. "Some of my older patients are still more deferential, but more and more, we talk with patients [...]
