题目:
The following appeared in a medical newsletter.
"Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. This hypothesis has now been proved by preliminary results of a study of two groups of patients. The first group of patients, all being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports medicine, took antibiotics regularly throughout their treatment. Their recuperation time was, on average, 40 percent quicker than typically expected. Patients in the second group, all being treated by Dr. Alton, a general physician, were given sugar pills, although the patients believed they were taking antibiotics. Their average recuperation time was not significantly reduced. Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment."
内容:
The argument above is well-presented, but not thoroughly well reasoned. The author concludes that all patients suffered from muscle strain should take antibiotics, and the hypothesis that secondary infections prolong the recuperation time is right. And, the mere evidence is the results of a study, concerning the different time two groups of patients need to heal from muscle injuries, which seems logical but contains several fallacies.
First, the author fails to convince me that the study is well conducted and I already find out some apparent flaws from it. There is no evidence to show me that the two groups of patients studied are the same in all other aspects except what pills they take during their treatment, maybe other factors cause the difference in time. It's possible that the classification of the two groups already determines the expectable result. If the patients of first group are averagely stronger than those in second, it is reasoned to believe that group one can heal faster. Even the author does not tell whether they are suffering more or less the same level injuries, the two groups should not be put together to compare. Furthermore, the doctor who treats the patients is important as treatment to any illness is not only giving pills but also communicating with them, pacifying their heart-pain. A brisk heart can accelerate the recovery. As the author tells us, Dr. Newland is a doctor specializing in sports medicine, who must be very experienced in treating muscle injuries, while Dr. Alton is just a general physician who may not know how to talk with patients and break their worries. This may attribute to the longer time to recuperate for group two.
Secondly, patients in group two don't necessarily suffer a secondary infection, while, someones in group one may suffer a secondary infection but they can still recover faster. Unless more information about patients who suffer a secondary infection is provided, the hypothesis that secondary infections prolong the recuperation time from severe muscle strain can not be proved. On the other hand , even assuming the results of the study mentioned in the beginning are valid, the hypothesis also can't be substantiated. The author makes a false analogy between severe muscle strain and muscle injuries. Perhaps, the antibiotics treatment which leads the rate of secondary infection to decrease intensely is very effective on the muscle injuries in the study. When applied to severe muscle strain, the antibiotics treatment may not be so effective. It is possible that other measures, such as surgery, will be better.
Last but not least, the author does not provide enough evidence to testify that taking antibiotics is the best way to treat muscle strain and it is suitable for all patients of that kind. "40 percent quicker than typically expected" may be insignificant compared with the efficacy of other methods. Besides, the argument does not mention the byproduction of antibiotics treatment, and It's possible that some patients are allergic to it. If misusage happens, fatal injuries may be brought about.
In sum, the reasoning behind taking antibiotics as part of their treatment for all patients who are diagnosed with muscle strain seems convincing, however, with the fallacious study, the antibiotics treatment should be taken carefully to any patient. Also, the author should rule out these possibilities before any conclusion is made. |
