问题 单项选择题

男性,62岁。因左侧面颊部阵发性烧灼样疼痛2月余就诊。每次发作持续10余分钟左右。体检:左侧眼眶下面颊部痛觉减退,咀嚼肌无力,角膜反射似较右侧迟钝。下列哪项处理是正确的()

A.积极查找病因,对因处理

B.一般无法明确病因,对症处理

C.首选卡马西平口服

D.手术切断三叉神经周围支

E.神经阻滞疗法

答案

参考答案:A

解析:本例为老年男性患者,病程已2月。临床主要表现为左侧三叉神经运动支和感觉支都有损害,多见于占位病变压迫或癌肿转移引起。应该积极查找病因,以免贻误诊治。原发性三叉神经痛一般仅累及三叉神经感觉支,以1~2支受累多见,运动支功能不受影响,即不会出现咀嚼肌无力。因此,针对原发性三叉神经痛的处理是不适当的。

     I am truly saddened about what is going on in my school district, especially in the school where I am

currently working.

    Why are so many students not doing well? Why is there such a huge achievement gap between urban

and suburban students? Just this week, in my school the seventh grade team leader called a meeting to

discuss academic detention (放学后留校). The purpose of the detention is to allow students who are

doing poorly a second chance to redo the work. Now if a student did not understand an assignment I

have no trouble allowing that student to redo a test or give some extra credit work, but if a student did

poorly because he/she opted(选择) not to do the work out of sheer laziness, that student should not be

given a second chance.

    And parents should be held accountable for their children. That is another reason why there is such a

huge achievement gap. All children should be monitored at home in order to achieve great success in

school. Perhaps it might be a great idea for urban school districts to offer free classes to parents on how

to help their students at home. Of course this idea is far fetched, after all we do not want to offend the

parents. What we will do instead is to spend a fortune on teacher training because if the kids are not

doing well it must be the fault of the teacher. That kind of mindset, if allowed to continue will be a perfect

recipe for greater achievement gaps.

     I started working at my current school in August and I have been in the teaching field for 25 years.

What I believe is that you can lead a horse to water but you can't make that  horse drink. You can't

force kids to change bad habits over  night, nor can we afford to lower standards just so a kid can  pass

a class.
