简介:背景:本研究旨在评估雄激素性秃发对有无头发脱落的男性的影响,并描述该类秃发引起患者应激状态的程度。方法:252名年龄在16~72岁之间的男性(175名有脱发,77名无脱发)参与本次研究。用脱发表格(5个关于社会人口统计学特征的问题,8个关于皮肤病学特征的问题,8个关于心理学评估的问题)和应急生活事件调查表进行调查。结果:有或无雄激素性秃发者对治疗的渴望明显不同(AGA;χ^2=5.877,d.f.=1,P=0.015)。不考虑雄激素性秃发(AGA)存在与否,参与者中61.4%认为AGA是一种自然状态,但需要寻找解决的方法,38.5%认为AGA是关注增加的一个原因,56.2%认为AGA对心理的影响主要是负面的。参与者中,认为AGA对家庭其他成员、异性关系和职业/学院生活产生负面影响的分别占37.1%、43.0%和36.3%。有或无雄激素性秃发者的心理学指标无显著性差异。

简介:成人T细胞性白血病/淋巴瘤(ATLL)是一种成熟辅助性T淋巴细胞恶性增殖性疾病,由人T淋巴细胞病毒-Ⅰ(HTLV-Ⅰ)感染所致。HTLV-Ⅰ感染流行于加勒比海地区、日本西南部、美洲南部及非洲。血清流行病学调查显示HTLV-Ⅰ感染亦流行于巴西。尽管HTLV-Ⅰ携带者显示病毒在T淋巴细胞内的整合呈多克隆性,但ATLL的各亚型患者显示病毒在肿瘤细胞内的整合为单克隆性。皮肤T细胞淋巴瘤(CTCL)是一组原发于皮肤的淋巴细胞增生性疾病,病因不明。最常见的两种表现为蕈样肉芽肿病(MF)和Sézary综合征(SS)。这两型CTCL的表现均与ATLL相似。因ATLL与CTCL的预后及治疗有根本不同,故在HTLV-Ⅰ流行地区必须严格区分这两种疾病。

简介:0引言调节性T细胞(Treg)即抑制性T细胞,具有免疫调节作用,使机体保持保护性免疫又不发生病理性免疫。效应性T细胞对免疫反应的启动和Treg对免疫反应的下调之间的失衡可导致皮肤慢性炎症或自身免疫。虽然在20世纪70年代就已描述了抑制性T细胞,但由于缺乏识别的标记,对此亚群的认识未有进展。20世纪90年代Sakaguchi等首先描述了一种天然存在于小鼠的表达CD25的CD4·T细胞。动物研究揭示此亚群细胞能抑制抗肿瘤免疫,预防多种自身免疫疾病,包括炎症性肠病和自身免疫糖尿病,并能诱导对皮肤同种移植物的耐受。其后,在人类也描述了此亚群。积累的证据提示这些细胞可能在多种皮肤病中起作用。
