问题 单项选择题

坏疽性阑尾炎出现寒战、高热、黄疸,要想到可能并发有

A.膈下脓肿
B.门静脉炎
C.肝脓肿
D.盆腔脓肿
E.急性胆管炎

答案

参考答案:B

解析: 急性阑尾炎的并发症包括:①腹腔脓肿;②内、外瘘形成;③化脓性门静脉炎:急性阑尾炎时阑尾静脉中的感染性血栓,可沿肠系膜上静脉至门静脉,导致化脓性门静脉炎症。临床表现为寒战、高热、肝大、剑突下压痛、轻度黄疸等。虽属少见,但如病情加重会产生感染性休克和脓毒症,治疗延误可发展为细菌性肝脓肿。行阑尾切除并大剂量抗生素治疗有效。故答案应选B。

单项选择题

The field of medicine has always attracted its share of quacks and charlatans — disreputable women and men with little or no medical knowledge who promise quick cures at cheap prices. The reasons why quackery thrives even in modern times are easy to find.To begin with, pain seems to be a chronic human condition. A person whose body or mind "hurts" will often pay any amount of money for the promise of relief. Second, even the best medical treatment cannot cure all the ills that beset men and women. People who mistrust or dislike the truths that their physicians tell them often turn to more sympathetic ears.Many people lack the training necessary to evaluate medical claims. Given the choice between (a) a reputable physician who says a cure for cancer will be long, expensive and may not work at all, and (b) a salesperson who says that several bottles of a secret formula "snake oil" will cure not only cancer but tuberculosis as well, some individuals will opt for "snake oil".Many "snake oil" remedies are highly laced with alcohol or narcotic drugs. Anyone who drinks them may get so drunk or stoned that they drown their pains in the rising tide of pleasant intoxication. Little wonder that "snake oil" is a popular cure-all for minor aches and hurts! But let there be no misunderstandings. A very few "home remedies" actually work. However, most remedies sold by quacks are not only useless, but often can be harmful as well.

According to the author, a very few home remedies are________.

A.useless

B.harmful

C.pleasant

D.effective
