问题 单项选择题 A2型题

男,30岁。左下颌后牙出现肿痛、张口困难1个月余。1个月前左下后牙急性冠周炎,张口受限,未做治疗。口腔检查:近中阻生,龈瓣稍红,叩诊(+)。左侧下颌支及腮腺咬肌区弥漫性肿胀发硬,轻微压痛,皮肤无红、热表现,无波动感。为明确诊断最需做的辅助检查是()

A.血常规检查

B.下颌骨升支切片位片检查

C.CT检查

D.磁共振检查

E.B型超声波检查

答案

参考答案:B

解析:此题为临床知识的简单应用,考核的是边缘性颌骨骨髓炎诊断的X线片位选择。首先根据病史不难判断这是一个智牙冠周炎引起的咬肌间隙感染,加之时间已经1个月余,所以首先要考虑患者已经有边缘性骨髓炎的可能性。对于它的诊断无疑应该了解下颌升支骨皮质有无增生或破坏,因此最佳的辅助检查手段应该是B。

On the first day of school I brought my camera to school. I gave the students a piece of 8 ×11 cardboard(纸板), and asked them to write their names on both sides. As they finished, I asked them to get into groups of three to four students and took photographs of them holding their name cards.

After school, I developed the film and printed two sets of photos. That evening, I started to match the names with the faces. I kept one set of pictures at home for about a week so that I could review their names each night. On the second day of school, I put up the other set of photos as a bulletin board (公布栏), with a title such as "Presenting Room 108, ..."

The kids loved it! After I had learned all of their names I brought the second set back to school and stuck them onto an 8 ×11 sheet of paper. I placed it in the classroom for other teachers.

The cardboard name cards that were made on the first day were collected and put on a shelf. From time to time, they were given back to the students and placed on their desks so that guests or supply teachers (代课老师) could identify all of the students.

I’ve been doing this with my grade 7 students for the last nine years and they liked it. It’s fun to bring the photos out again at the end of the school year to see how much they have all changed in ten months.
