When the pain reliever Vioxx was withdrawn from the worldwide market last September after the announcement that it inc

4、reased patients risk of heart attacks and strokes, millions panicked. Suddenly, ads for the drug were replaced with ads looking for Vioxx “victims“. Not only did patients stop taking Vioxx but, doctors say, many people stopped taking their other medicines, too sometimes putting their health at serio

5、us risk. The sometimes-sensationalized headlines didnt help. People wondered. Should I trust my doctors? Could what I thought would help me actually kill me? Is the drug safety system broken? Americans have somehow come to believe they should get the best medical care with the latest remedies with n

6、o side effects. But there is no drug that doesnt have side effects. Peter Corr, head of worldwide research and development for drug manufacturer Pfizer says, “As a society we expect medicine to be perfect. There is no such thing. There is always a risk.“ How You Can Make Informed Decisions Since the

7、re is no such thing as a pill that is completely safe, including aspirin, consumers have to accept the dichotomy(一分为二 )that the same medicines that extend and enhance our lives may hurt us; some of them may merely have minor side effects, while others are able to cause death. So how should you and y

8、our doctor proceed? 1. Weigh the risks and benefits of any drug. As a smart consumer you must decide whether a drug is “safe enough“ for you. The greater the benefit, the more risk you may be willing to take. If your illness is mild and not very bothersome, you may decide that any risk is too big an

9、d opt against taking any medications at all. On the contrary, if your illness is serious or potentially life threatening, you may even be willing to try an experimental drug with greater risk for serious side effects. Zena McAdams, 59, a regional clergyman in Macon, Georgia, has lived with a conditi

10、on that causes chronic pain for many years. For a long time she took OTC ibuprofen(布洛芬 ,一种镇痛非处方药 ), “I mean lots of it,“ she says. In the spring of 2001, her doctor prescribed Vioxx. Taken only once a day, it was “remarkable,“ she says. “I took it every day till it was taken off the market.“ After s

11、peaking to her doctor, she switched to Celebrex last October. It was also effective in controlling the aches and pains associated with her condition until she heard concerns that it, too, had serious potential side effects. She talked to her doctor, weighed the risks versus the benefits and decided

12、that her quality of life was most important. “There is always that nasty feeling about safety,“ she says, “but there is no reason to think that I have any heart problems. The benefits at this point in my life certainly outweigh the risks. The drug works. It eases the pain.“ 2. Be especially cautious

13、 about new drugs. New drugs are inherently risky. So if youre taking one, monitor yourself carefully. Have your eating and digestive habits changed? Are you feeling unusually tired or agitated? Have your breathing patterns or skin color changed? If so, call your doctor immediately, who may tell you

14、to stop taking the drug. How does a consumer know that a drug is new? Ask your doctor or pharmacist(药剂师 )? If you have a choice between two or more equally effective drugs, choose the one with a longer track record of safety. If you are taking a drug in the same class as one that has been recalled,

15、it is careful to ask your doctor if that drug places you at greater risks. 3. Know if youre in a high-risk group. Although scientists still dont know precisely why, certain individuals have bad reactions to a drug or to a particular dose of a drug, while others dont. Men metabolize(新陈 代谢 )drugs diff

16、erently than women do, for example. Be especially watchful if you are very young, very old or pregnant. Drugs usually arent tested on these groups. “I worry the most about the elderly,“ says Avorn. “They are vastly under-represented in trials of drugs, yet they are the most likely to be taking the d

17、rugs when they are approved.“ 4. Ask the right questions. When you get a new prescription, never leave the doctors surgery without a clear understanding of why youre taking the drug, how to take it, and how youll know if its working. Even if it makes you a bit uncomfortable, ask. You are responsible

18、 for your own health and safety. “If the doctor doesnt want to answer questions, you should probably find an other doctor,“ says Avorn. After your visit, if you still have questions, call or e-mail the doctor. Use your pharmacist as an expert consultant for any additional concerns you have about the

19、 drug or its side effects. You can ask the pharmacist for the professional package insert(插页 )for the drug, says Corr. Although its written for health care providers, it includes information on clinical trials and side effects. Also, if theres been a label change, with new information about the drug

20、 or any warnings, it will be part of the PPI(保险证 明 ). Or request more consumer-friendly information, which should tell you how to use the drug properly and warn of any precautions. You can also call the drug companys toll-free number for more information, or go to its web-site. 5. Be informed, and f

21、ollow directions carefully. Check that the pills you receive are the correct ones. Errors crop up in the dispensing of medications: Its easy to confuse products with similar names(for example, Zantac and Xanax). Read the instructions and take your pills exactly as prescribed. Be alert for expiration

22、 dates, and stay attentive to recalls and warnings. Tell your doctor about any other medications you take, either prescribed or OTC(over the counter). Drug interactions can cause serious problems. For ex ample, Posicor, an anti-hypertensive drug(治疗高血压的药 ), was taken off the market because it could c

23、ause blood pressure to drop sharply when used with other heart medications. If you fill all your prescriptions at the same store, the pharmacist may be able to warn you of known interactions. It is vitally important that patients and their doctors provide feedback to manufacturers and regulators if

24、they have any suspicion of a problem. Then these signals will be known and can be analyzed to see if they are more widespread, which could save lives. 2 Every drug has some side effects. （ A） Y （ B） N （ C） NG 3 The greater the benefit, the less risk you are to take. （ A） Y （ B） N （ C） NG 4 The reaso

Does the newspaper photographer try to stop a woman, from jumping off a bridge to her death or does he photograph the plunge? You are told by your editors,

34、quite appropriately, not to become part of the story. On the other hand, isnt the saving of a life more important? Such incidents place the reporter or photographer in an ethical dilemma. But even if this type of coverage is not your style, theres a good chance that sooner or later you will have to

35、do it. When that occurs, think clearly and set aside your emotions. Keen in mind that you have a duty to your readers, listeners or viewers to keep them informed. There is good reason for media interest in such events. For many years, surveys of news consumers have shown that accidents, fires and di

36、sasters rank with crime and government news near the top of items of reader interest. Those studies confirm what editors know spontaneously: The job of the news media is to get information to the public as quickly and accurately as possible. The media also cover these events in their capacity as wat

37、chdog for the public over government agencies. In the police are slow in responding to an accident, is it because there are not enough officers or because they are poorly supervised?

There are many knock-on effects all over

43、the world. The home of El Nino is Peru.

Up and down the country, form desert to highlands, El Nino weather phenomena have brought des

44、tructive floods, costing 200 million in immediate and long-term damage, and undoing the work of many development projects. “The destruction is near total,“ Dominic Brain, a worker for Christian Aid reported. “Few of the houses could withstand the floodwater. Today I visited Acomayo, a shantytown(贫民区

45、 )where 17,500 people once live. Now only ten percent of the houses are still standing. The bulk of the population has lost all their possessions.“ The town of Ica seldom sees rain. Houses for the poor are built of adobe - sun-baked mud - standing side by side in long terraces. When the River Ica bu

46、rst its banks in late January, 15,000 houses were swiftly flooded. Up to 5,000 houses were destroyed - a sign not only of the force of the river, which loosened huge rocks and swept them falling down from the Andean mountains, but of the vulnerability of the homes which hardly ever face rain. “They

47、melted like chocolate,“ exclaimed an eye-witness. “The extent of the damage was terrible!“ Almost immediately health became a problem. Without proper plumbing(排水 ), waste matter rose to the surface of the floodwaters. People received cuts walking through the floodwater and mud. Cholera - epidemic in

48、 Peru in the early nineties - returned, with 90 reported cases in Ica province alone. Tile entire city seems to have drowned - first in floodwaters 1.5 meters high, and then in mud.
