简介:寻常狼疮是皮肤结核中最常见的类型,约占所有皮肤结核患者的半数。本病易侵犯儿童和青少年,好发于面部,影响容貌。我们用异烟肼、乙胺丁醇和利福平联合治愈寻常狼疮2例,报告如下。
简介:目的探索VISIA皮肤测试仪在黄褐斑病情评估中的应用价值。方法选择2014年1月—2015年12月于中国医学科学院整形外科医院激光美容中心就诊的黄褐斑患者72例,利用VISIA皮肤测试仪对斑点、紫外线光斑、红色区域、棕色斑等指标进行测试评分;同时行目测法评估的黄褐斑皮损面积和严重度指数(MASI)评分。分析VISIA检测各指标值与人工目测法计算所得MASI评分间的相关性。结果斑点、红色区域、棕色斑无论特征值和分值与MASI评分呈正相关,而紫外线光斑与MASI评分结果无相关。结论VASIA皮肤测试仪可用于判定黄褐斑的临床严重度。

简介:目的:探讨子宫内膜采集器诊断不孕患者子宫内膜病变的临床情况,以期提高临床治疗水平.方法:回顾性分析2010年1月至2013年1月70例不孕疑似子宫内膜病变患者,采集子宫内膜组织,将获取的子宫内膜组织进行细胞涂片并浸入10%甲醛液中固定,对其中出现颗粒状的成形成分进行石蜡切片和组织学分析,同时对所有患者进行诊断性刮宫,以其病理结果作为“金标准”,对子宫内膜采集器细胞涂片法、有形成分石蜡切片法和两组结合的方法在诊断率上的符合程度、敏感性和特异性情况加以分析.结果:子宫内膜采集器细胞涂片法和子宫内膜采集器有形细胞成分石蜡涂片法符合率分别为84.3%、94.7%,两者比较有明显差异性(P<0.05),而两者结合和有形细胞成分石蜡涂片法符合率分别为95.2%、94.7%,两者比较元明显差异性(P>0.05).结论:子宫内膜采集器不仅可以用于涂片法进行细胞学诊断,也可对子宫内膜的有形成分进行石蜡切片组织学诊断,这样会提高诊断符合率.
