单选题Celebrate. Celebrate. Physicians are delighted with a Food and Drug Administration (FDA) advisory panel's recommendation earlier this year that Vioxx and its cousins Bextra and Celebrex (all medicines known as Cox-2 inhibitors) should remain on the market, despite evidence they increase heart disease risk in some people. The panelists reached their decision after weighing all the data and concluding the benefits of these pain-relieving drugs outweighed the risks. Specifically, these scientists acknowledged that, for some patients, these prescription drugs were uniquely effective in reducing pain from arthritis and other causes. For others—concerned about ulcers associated with aspirin and other OTC analgesics—the Cox-2 inhibitors offered the advantage of minimizing potentially serious effects of stomach irritation. Now is an appropriate time for everyone to take a fresh look at the benefit-risk equation for Vioxx and the other Cox-2 inhibitors. The risks-increased risk of heart disease in some who use the drugs—have been well publicized. Much less publicity has been given to a spectrum of real and potential benefits that go way beyond reduced risk of stomach irritation. These little-discussed benefits would have been lost, perhaps permanently-had Vioxx, Bextra and Celebrex been driven from shelves in pursuit of perfect safety, an unattainable goal. For example, there is substantial evidence Cox-2 inhibitors can reduce development of colon polyps, which may become colon canceL Indeed. Celebrex is FDA-approved for those genetically prone to colon cancer. Ironically, the 2004 study that revealed the elevated heart attack risk of Vioxx was primarily designed to further establish the drug's effectiveness in protecting against colon cancer. And while the results of that interrupted trial have not yet been published, there is good reason to believe they will confirm the protective effects against colon cancer established in research over the last 10 years. At the time of its withdrawal from the market last fall, studies of Vioxx as well as the other Cox-2 drugs suggest that they had other anti-cancer properties as well, possibly reducing the risk of malignancies of a number of sites, including the lung and esophagus. Had these drugs been dismissed, their untapped promise for prevention would have evaporated well before it was evaluated and applied to save lives. Fortunately, cooler and wiser heads prevailed.

单选题 With the understanding of phobias has come a magic bag of treatments: exposure therapy that can stomp out a lifetime phobia in a single six-hour session; virtual-reality programs that can safely simulate the thing the phobia most fears, slowly stripping it of its power to terrorize; new medications that can snuff the brain's phobic spark before it can catch. In the past year, the U. S. Food and Drug Administration approved the first drug—an existing antidepressant. Most psychologists now assign phobias to one of the three broad categories: social phobias, in which the sufferer feels paralyzing fear at the prospect of social or professional encounters; panic disorders, in which the person is periodically {{U}}blindsided{{/U}} by overwhelming fear for no apparent reason; and specific phobias—fear of snakes and enclosed spaces and heights and the like. If you are living with a generalized sense of danger, it can be profoundly therapeutic to find a single object on which to deposit all that unformed fear—a snake, a spider and a rat. A specific phobia becomes a sort of backfire for fear, a controlled blaze that prevents other blazes from catching. But a condition that is so easy to pick up is becoming almost as easy to shake, usually without resort to drugs. What turns up the wattage of a phobia the most is the strategy the phobias rely on to ease their discomfort: avoidance. The harder phobics work to avoid the things they fear, the more the brain grows convinced that the threat is real. Progress in treating social-anxiety disorder is also providing hope for the last—and most disabling—of the family of phobias: panic disorder. Panic disorder is to anxiety conditions what a tornado is to weather conditions: a devastating sneaks havoc and then simply vanishes. Unlike the specific phobic and the social phobic who know what will trigger their fear, the victim of panic attacks never know where or when one will hit. Someone who experiences an attack in, say, a supermarket will often not return there, associating the once neutral place with the traumatic event. But the perceived circle of safety can quickly shrink, until sufferers may be confined entirely to their homes. When this begins to happen, panic disorder mutates into full-blown {{U}}agoraphobia{{/U}}. The treatment for agoraphobia is much the same as it is for social phobia: cognitive-behavioral therapy and drugs.
