30%超分子水杨酸与低浓度甘醇酸在轻中度寻常性痤疮治疗中的疗效评价

目的:比较30%超分子水杨酸与低浓度甘醇酸治疗轻中度寻常性痤疮的疗效。方法:对2018年1月-2019年6月就诊于中国人民解放军总医院第一医学中心的86例轻、中度寻常性痤疮患者分别进行水杨酸或甘醇酸治疗,其中甘醇酸组48例,水杨酸组38例,共治疗3次,每次间隔时间2~3周,第1次治疗时、第2次治疗时、第3次治疗时及第3次治疗后4周随访(分别为V0、V1、V2、V3),记录患者痤疮分级、粉刺、炎性丘疹、脓疱、结节及GAGS评分。结果:V0时水杨酸治疗组粉刺17.00(13.00, 61.00)个、炎性丘疹32.00 (17.00, 67.00)个、 GAGS评分14.50 (14.00, 16.00)分;V0时甘醇酸治疗组粉刺24.50(11.00,44.00)个、炎性丘疹27.00(19.50,37.50)个、GAGS评分14.00(13.00,18.00)分。V3时水杨酸治疗组粉刺8.00(5.00,19.00)个、炎性丘疹20.00(10.00,22.00)个、GAGS评分11.00(9.00,13.00)分。V3时甘醇酸治疗组粉刺8.50(3.00, 21.00)个、炎性丘疹13.50 (10.00, 21.50)个、GAGS评分11.00 (9.50, 12.50)分。超分子水杨酸和低浓度甘醇酸两组间有效率及GAGS评分差异无统计学意义(P>0.05),两组内V3较V0皮疹减退率、有效率及GAGS评分差异均有统计学意义(P<0.05)。炎性丘疹方面甘醇酸组在治疗2次后较基线比差异有统计学意义,而水杨酸组在治疗3次后较基线比差异有统计学意义,两组治疗过程中均未出现明显不良反应。结论:30%超分子水杨酸与低浓度甘醇酸在轻中度寻常性痤疮治疗中均有效,在炎性丘疹治疗方面甘醇酸起效更快,但水杨酸的安全性略高。     

Gastric Cancer and Paraneoplastic Pemphigus

Paraneoplastic pemphigus is a relatively rare but significant acquired autoimmune mucocutaneous disorder that is characterised by diffuse erythema, painful blistering and sores of the skin and mucus membranes. The underlying pathogenesis is believed to be triggered by altered immune system in response to underlying neoplasm. The manifestations can predate, occur at the same time or after the diagnosis of cancer. Associations with gastric cancer have only been reported twice. A 78-year-old lady presented with a month’s history of extensive skin lesions that started off as bullous lesions and biopsy revealed bullous pemphigus. Endoscopy for anemia revealed gastric cancer. This case reinforced the need to consider underlying malignancy in elderly patient with new onset dermatological presentation.     

高通量测序分析重度寻常痤疮患者和健康人肠道菌群差异

目的 利用高通量测序技术分析重度寻常痤疮患者和健康人肠道菌群的差异.方法 门诊确诊的重度寻常痤疮患者10例及年龄、性别相匹配的健康人10例,分别收集粪便标本,提取细菌DNA,行16S rRNA测序鉴定微生物的种类,并进行菌群差异分析.结果 两组肠道菌群多样性未发现显著差异,仅在肠道菌群的相对丰度上发现个别具有显著差异的菌.两组标本主要由拟杆菌门、厚壁菌门、变形菌门、放线菌门组成.比较两组在门、属水平上菌群相对丰度,差异均无统计学意义;在种水平上,Blautia producta、Coprococcus eutactus在两组间差异有统计学意义.结论 重度寻常痤疮患者和健康人相比,菌群多样性指数未见明显差异.但某些细菌菌种存在显著差异.
