简介:临床资料患者,男,46岁。主因右侧鼻腔外侧缘赘生物15d,于2010年8月就诊。患者15d前右侧鼻腔外侧缘出现赘生物,逐渐增大,无明显自觉症状。1个月前双足跖曾出现红斑、脱屑,自行外用抗真菌制剂治疗无明显好转。随后双手出现类似皮损,未消退。患者既往体健,否认输血史、介入治疗史等,有数次冶游史。其配偶未来我科就诊。各系统检查未见异常。皮肤科检查:右侧鼻腔外侧边缘见一蚕豆大小扁平丘疹(图1a),双手掌、双足跖可见铜红色圆形、弧形斑疹,边缘附黏着性鳞屑,似领圈样(图1b,1c)。肛周可见2枚黄豆大小粉红色扁平丘疹,边界清晰,基底无明显红晕,表面湿润呈细颗粒状,无糜烂、渗液,质地较柔软(图1d)。鼻部及肛周皮损行醋酸白试验颜色改变不明显。实验室检查:梅毒螺旋体明胶凝集试验(TPPA)阳性,快速血浆反应素环状卡片试验(RPR)1∶32;血清人免疫缺陷病毒(HIV)检测阴性;钳取右侧鼻翼及肛周皮损行聚合酶链反应检测人乳头瘤病毒(HPV)阴性。患者拒行组织病理检查。诊断:二期梅毒。治疗:长效青霉素240万U分两侧臀部肌内注射,每周1次,连续3次。3个月后复诊,RPR滴度1∶4,临床症状基本消退。随访至2012年9月,复查RPR阴性,TPPA阳性。

简介:目的观察急性期湿疹住院患者临床特征及治疗周期。方法对175例急性湿疹住院患者的病历资料进行统计分析。结果175例患者中男81例,女94例,平均发病年龄(45.98±21.79)岁。其中首次发病者57例占32.55%,属慢性湿疹急性发作者118例占67.45%。其中19例(10.86%)认为有明显的诱发因素。有25例患者(14.28%)曾患有其他过敏性疾病。渗出物细菌培养以金黄色葡萄球菌为主。复方甘草酸苷的总体治疗周期与糖皮质激素相比差异没有统计学意义,但起效时间相对较慢。结论急性湿疹患者常有慢性湿疹病史,多无明显诱因,常伴随皮肤细菌感染。复方甘草酸苷治疗急性湿疹疗效确切,患者住院时间与糖皮质激素相比无统计学意义,不良反应小,可以作为急性湿疹的治疗方法之一。
