1.没有提供study的详细信息，可能两个医生的方法不同或者是别的原因导致了康复期加快（没有控制其他变量一致）样本大小未知

2. 没有提供信息说明二次感染和肌肉拉伤病人之间有什么关系，或者是肌肉拉伤病人容易二次感染

3.也没有说明抗生素是否具有副作用或其他不好的作用，

In this newsletter, the author claims that all patients who are diagnosed with muscle should take antibiotics during their treatment. He relies his conclusion basically on a case study which comparing the different treatment to two groups of similar patients. However, the study of these two groups of patients remains so many uncertainty, let alone lack information about the function and side effect antibiotics would have, that I can not be convinced to accept it.

Obviously, the author's argument rests on the threshold assumption that the two groups of patients who are diagnosed with muscle strain are almost the same in any perspective, which means the same amount of patients, the same original symptom, the same nutrition condition, the same structure of patients' age, and the same doctor who heals them. Plenty of experimental restrictive conditions, which should be given to form a logical and persuasive conclusion, are not designated by the author. Any restrictive condition's change or different might lead to a false or questionably result of a case study or experiment. Even experimental condition is under control, there is still one big scientific mistake that one case study can not make a strong conclusion. In addtion, the author fails to tell how many patients were treated, it is very important because the fewer the patients participate in an experiment, the more inaccurate and random the result is.

Secondly, the author fail to provide enough information that secondary infection has a direct relation with muscle strain. As we all know, not all kinds of muscle strain are probably to get a secondary infection, especially those who are not seriously injured and has no exposure of inside organise. Therefore, there is no need to treat such patients with antibiotics. Plus, none sufficient evidence that patients of muscle strain have a higher probability to get secondary infection than others.

Thirdly, the author has not mentioned any side effect of antibiotics which is absolutely one of the most important things every doctor should concern about. As I know, side effect of antibiotics can be hypersusceptibility, fastness of such kind of medicine, endanger weak people like children and pregnant women, and so on. None of them is mentioned, so how can I trust this conclusion that all patients who are diagnosed with muscle strain should be advised to take antibiotics as treatment?

To sum up, in my point of view, the author relies his conclusion on some suspect assumptions and a single study, therefore his recommendation that all patients have muscle strain should be advised to take antibiotics is not persuasive enough. To strengthen it, the author should have more information about antibiotics and search for more reliable case studies.
