简介:目的探讨应用水射流辅助吸脂术行全身大容量吸脂的临床效果和安全性。方法对我科32例患者、共139个部位行水射流辅助吸脂,记录手术时间、注入肿胀液量、冲洗液量、吸出总液体量、吸出脂肪量、术后疼痛时间,观察吸出物颜色、术中术后患者生命体征、皮肤瘀斑和水肿的程度、皮肤平整度以及利多卡因毒性反应等并发症出现情况。结果本组患者平均手术时间4.5h,平均吸脂4.8个部位,平均注入肿胀液量1850ml,平均注入冲洗液量15760ml,平均吸出总液体量11480ml,平均吸脂量4720ml,平均疼痛恢复时间5天。术后6个月恢复良好,无并发症发生。结论水射流辅助吸脂对神经和血管的损伤小,组织肿胀轻,手术效果较好。
简介:目的:分析我院皮肤性病科门诊生殖道沙眼衣原体感染患者的临床特征及随访情况。方法:回顾性分析我院2013年4月至2015年10月经聚合酶链反应(PCR)确诊并有治疗后PCR随访结果的103例生殖道沙眼衣原体感染患者的临床及随访资料。结果:103例生殖道沙眼衣原体感染患者中,男性67例(65.05%),女性36例(34.95%),年龄17~58岁,平均(29.48±6.79)岁。38.83%(40/103)患者无明显临床症状,其中男性患者中29.85%(20/67)无明显临床症状,女性患者中55.56%(20/36)无明显临床症状。56.31%(58/103)患者存在混合感染,45.63%(47/103)合并解脲脲原体感染,10.68%(11/103)合并淋病。92.23%(95/103)患者治疗后PCR复查沙眼衣原体核酸阴性。结论:生殖道沙眼衣原体感染患者常为混合感染,且临床症状轻微或隐匿,临床应对有不安全性行为史的患者及其性伴做全面性病检查。PCR方法值得在生殖道沙眼衣原体感染患者的诊断及随访中推广使用。

简介:在地铁建筑工人中暴发可疑的接触性皮炎被疑系一种新的以双酚A/F为基质的环氧树脂系(ERS)所致。建筑工人在向混凝土墙壁中插入铁栏时应用了ERSs。本研究旨在明确ERS的成分(如果有)是否可导致接触性皮炎。对22例接触过ERS的建筑工人中的20例进行斑贴试验,7例对组分A发生反应的患者中的5例接受该组分的不同亚成分的斑贴试验。有9例患者(9/22,40.9%)出现可疑接触性皮炎的临床症状及体征。这9例中有7例对组分A发生阳性反应,而11例无症状个体对组分A均未发生反应,所有个体对组分B均为阴性反应。5例接受进一步斑贴试验的个体中,全部对间一苯二甲基二氨发生反应,4例对1,6-己二醇二环氧甘油醚发生反应,3例对F型双酚及0.25%凡士林三羟甲基丙烷三甘油醚的环氧树脂发生反应,仅有1例对A型双酚的环氧树脂发生反应。ERSs引发的接触性变态反应可能涉及硬化剂、稀释剂及树脂,应对其所有成分进行斑贴试验。
简介:背景:t(14;18)(q32;q21)累及IGH和MALT1已在皮肤MALT淋巴瘤和1例原发皮肤弥漫性大B细胞淋巴瘤(DLBCL)中被描述。但是,IGH/MALT1转位在这些类型皮肤淋巴瘤的发生率还不清楚。方法:作者用MALT1和IGH分裂探针对16例皮肤MALT1淋巴瘤和16例原发皮肤DLBCL患者的石蜡切片进行分裂间期荧光原位杂交(FISH),以评价IGH/MALT1转位的频率,筛选其他有关IGH和MALT1位点的潜在转位。结果:16例皮肤MALT1淋巴瘤和16例原发皮肤DLBCL患者中,均未检测到累及MALT1的转位。能够进行IGH转位分析的12例MALT淋巴瘤患者均为阴性。相反,能够进行IGH转位分析的13例(31%)例原发皮肤DLBCL患者中有4例阳性。之后的FISH分析显示其中1例为IGH/BCL2转位,1例为CMYC/IGH转位,而剩余2例的转位配对目前还未发现。结论:该研究显示累及MALT1的转位,包括IGH/MALT1在皮肤MALT淋巴瘤和原发皮肤DLBCL中不常见。其他累及IGH的转位也不参与至少大多数皮肤MALT淋巴瘤的发病。相反,原发皮肤DLBCL在少数病例中可有几种IGH转位中的一种。
