简介：甲状腺癌是临床上常见的恶性肿瘤，约占全身肿瘤的1，3％，占头颈部肿瘤的5．1％。病理类型分为乳头状腺癌（60％～80％）、滤泡状腺癌（20％）、髓样癌（3％-10％）及未分化癌（15％）。分化型甲状腺癌包括乳头状腺癌和滤泡状腺癌，发病率高，生长缓慢，恶性程度较低。由于基层医院在术前诊断方面的欠缺，术中往往没有冷冻病理检查，造成手术不规范，需要再次手术修正。现对我院52例需再次手术的分化型甲状腺癌病例进行分析，总结如下。

简介：角膜感染如果不能很快的诊断和恰当的治疗,可使角膜失去透明性而致盲。“微生物性角膜炎”、“感染性角膜炎”和“化脓性角膜炎”都是指角膜的化脓性感染。在这篇文章里,我们使用“微生物性角膜炎”这一概念。这些感染的特征是角膜实质层的黄白色浸润,伴或不伴角膜上皮的缺损,常有炎性反应。（图1）微生物性角膜炎的最常见主诉如下（包括不同的严重程度）：·眼红·疼痛·视物模糊·畏光·流泪这篇文章将回顾细菌性和真菌性角膜炎,

简介：目的探讨小梁切除术中连续锁边缝合的两种不同结膜瓣对泪膜稳定性的影响。方法双眼原发性青光眼患者26例,双眼均行小梁切除术,左眼组：以穹窿部为基底的结膜瓣组26例26眼;右眼组：以角膜缘为基底的结膜瓣组26例26眼,两组中结膜瓣均采用连续缝合密闭切口,并检测术前1d、术后1d、7d、14d、30d、60d的泪膜破裂时间（BreakupTime,BUT）、基础泪液分泌试验（SchirmerItest,SIT）、角膜荧光素染色积分（fluorescenceintegral,FI）。结果两组间BUT、SchirmerI试验于术后1d、7d、14d、30d及60d比较差异均有统计学意义（均P0.05）。结论连续锁边缝合的以穹窿为基底结膜瓣的小梁切除术显著降低了泪膜的稳定性,为提高患者的舒适度我们主张以角膜缘为基底作为手术切口。
