单选题Some Sleep Drugs Do More Than Make You Sleep The United States Food and Drug Administration has ordered companies to place strong new warnings on thirteen drugs that treat sleep disorders. It also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drugs. Last Wednesday, the FDA announced that some of these drugs can have unexpected and dangerous effects. These include the risk of life-threatening allergic reactions. They also include rare incidents of strange behavior. These include people cooking food, eating and even driving while asleep. The patients later had no memory of doing these activities while asleep. Last year, a member of the United States Congress said he had a sleep-driving incident. Patrick Kennedy, a representative from Rhode Island, crashed his car into a security barrier near the building where lawmakers meet. The accident happened in the middle of the night and no one was hurt. Mr. Kennedy said he had earlier taken a sleep medicine. He said he was also being treated with a stomach sickness drug that could cause sleepiness. The Food and Drug Administration did not say in its announcement how many cases of sleep-driving it had documented. However, the New York Times reported last year about people who said they had strange sleep events after taking the drug Ambien. Some reported sleep-driving and sleep-walking. Others said they found evidence after waking in the morning that they had cooked food or eaten in their sleep. But they had no memory of carrying out the activities. A. Food and Drug Administration official says that these serious side effects of sleep disorder drugs appear to be rare. But, he also says there are probably more cases than are reported. He says the agency believes the risk of such behaviors could be reduced if people take the drugs as directed and do not drink alcohol while taking the drugs. The Food and Drug Administration has advised drug companies to carry out studies to investigate the problem.

"The incidence of serious and fatal adverse drug reactions (ADRs) in US hospitals was found to be extremely high," say researchers at the University of Toronto in Ontario, Canada. They carried on an analysis of 39 ADR-related studies at US hospitals over the past 30 years and defined an ADR as "any harmful, unintended, and undesired effect of a drag which occurs at doses used in humans for prevention, diagnosis, or therapy." An average 6.7% of all hospitalized patients experience an ADR every year, according to the researchers. They estimate that "in 1994, overall 2,216,000 hospitalized patients had serious ADRs, and 106,000 had fatal ADRs." This means that ADRs may rank as the fourth single largest cause of death in America. And these incidence figures are probably conservative, the researchers add, since their ADR definition did not include outcomes linked to problems in drug administration, overdoses, drug abuse, and therapeutic failures. The control of ADRs also means spending more money. One US study estimated the overall cost of treating ADRs at up to $4 billion per year. Dr. David Bates of Brigham and Women's Hospital in Boston, Massachusetts, believes that healthcare workers need to pay more attention to the problem, especially since many ADRs are easily preventable. "When a patient develops an allergy or sensitivity, it is often not recorded," Bates notes, "and patients receive drugs to which they have known allergies or sensitivities with disturbing frequency." He believes computerized surveillance systems — still works-in-progress at many of the nation's hospitals — should help cut down the frequency of these types of errors.

单选题{{B}}第二篇{{/B}} {{B}} Common-cold Sense{{/B}} You can't beat it, but you don't have to join it. Maybe it got the name "common cold" because it's more common in winter. The fact is, though, being cold doesn't have anything to do with getting one. Colds are caused by the spread of rhinoviruses, and, at least so far, medical science is better at telling you how to avoid getting one than how to get rid of one. Children are the most common way cold viruses are spread to adults, because they have more colds than adults--an average of about eight per year. Why do kids seem so much more easily to get colds than their parents? Simple. They haven't had the opportunity to become immune to many cold viruses. There are more than 150 different cold viruses, and you never have the same one twice. Being infected by one makes you immune to it--but only it. Colds are usually spread by direct contact, not sneezing or coughing. From another person's hand to your hand and then to your nose or eyes is the most common route. The highest concentration of cold viruses anywhere is found under the thumbnails of a boy, although the viruses can survive for hours on skin or other smooth surfaces. Hygiene is your best defense. Wash your hands frequently, preferably with a disinfectant soap, especially when children in your household have colds. But even careful hygiene won't ward off. every cold. So, what works when a coughing, sneezing, runny nose strikes? The old prescription of two aspirins, lots of water, and bed rest is a good place to start. But you'll also find some of the folk remedies...Hot mixtures of sugar (or honey), lemon, and water have real benefits. rhinovirus n.鼻病毒 immune adj. 免疫的,有免疫力的 disinfectant n. 消毒剂,杀菌剂 sneeze vi. 打喷嚏 thumbnail n.拇指
