Ageing and photoageing of keratinocytes and melanocytes   总被引:3,自引:0,他引:3  
An overview of keratinocyte and melanocyte function is provided. The processes of cutaneous ageing and photoageing are defined, and age-associated modulations in gene expression are described. The changes in keratinocytes and melanocytes that occur with skin ageing and photoageing and the characteristics of chronologically aged vs. photoaged skin are delineated. Mutations that are found in malignant and premalignant tumors of epidermal origin are described.  相似文献

Angiosarcoma of the face and scalp (AS) is a rare but well-recognized vascular tumour, generally accepted to have a very poor prognosis. However, most previous studies have been limited because of small patient numbers.
We have collected clinical data on 71 patients with AS from the time of initial histological diagnosis. Information obtained included age at diagnosis, sex, race, clinical appearance and size of lesions, therapeutic procedures, clinical course, incidence of metastases, survival time and response to therapy.
All the patients were Caucasian with a mean age of 74 years (range 56–72 years) and a male to female ratio of 1:5:1. Tumours occurred predominantly on the upper face and scalp but male patients frequently presented with central facial lesions. Three main clinical patterns were confirmed: nodules, bruise-like induration and areas of ulceration with bleeding.
Most patients were treated by radiotherapy (64%) or by excision alone (10%). The remainder received no therapy or combined therapy. Radiotherapy-treated patients fell into two groups: group I (71%) had short survival times ( x= 13.5 months), large lesions (63% < 10 cm), and a high incidence of metastatic disease (50% of patients); group 2 patients (29%) survived longer ( x = 5.5 years) and had a low proportion of large tumours (8%) with a low incidence of metastatic disease (8%). Patients treated by excision alone had a high incidence (86%) of metastatic disease.
Our data suggests that AS remains a disease of poor prognosis in elderly patients with large lesions. However, small (< 5 cm) lesions have a far better prognosis and the use of radiotherapy may be associated with prolonged survival and a lower incidence of metastases than simple excision.  相似文献

目的:对两种氯雷他定(百为坦和开瑞坦)治疗湿疹、皮炎的成本效果进行分析.方法:将患者分为两组,每组30例,分别服用百为坦和开瑞坦,除观察疗效外还进行成本效果分析。结果:两组疗效相当,均无明显的不良反应。但百为坦的治疗成本明显低于开瑞坦.结论:氯雷他定治疗湿疹、皮炎疗效高,安全性好。百为坦比开瑞坦治疗成本低。  相似文献

Adequate instrument handling and sterilization are important aspects of office surgery. Heat sterilization is the most reliable choice. The steam autoclave is highly recommended. Dry heat is effective but can pose some storage problems. Gas sterilization is useful for heat-sensitive materials but not practical for the private office. Cold "sterilization" is not reliable for incisional surgery. In addition to proper sterilization modality selection, the surgeon must observe important standards of instrument care, packing, and storage.  相似文献

光损伤性皮肤病规范化防治体系的构建及应用   总被引:1,自引:0,他引:1  
目的构建光损伤性皮肤病规范化防治体系,提高疾病治愈率,减少复发率。方法基于疾病信息管理软件平台,开设专病门诊,建立信息化患者管理档案,分析疾病发生发展规律,制定个性化治疗方案,长期追踪病人,评估疗效和进行健康教育。结果自2004年至2014年,建立患者档案24800例。明确了皮肤癌、多形性日光疹、痤疮和黄褐斑的危险因素。证实光损伤性皮肤病均存在皮肤屏障受损,使用皮肤屏障修复剂是首要治疗措施。制定了日光性角化病、多形性日光疹、痤疮及黄褐斑的规范化诊疗指南。疾病治疗总有效率从73.3%增至93.3%,复发率从76.7%降至30.0%。结论应用规范化防治体系能节省医疗支出、提高人民群众身心健康水平,是今后新医疗模型的发展方向。  相似文献

Structure and function of ethnic skin and hair   总被引:4,自引:0,他引:4  
Differences have been found among blacks, whites, Asians, and Hispanics in various areas of skin structure and function. Among them is the stratum corneum lipid (ceramide) content, which is highest in Asians, then Hispanics, then whites, and lowest in blacks. Melanosomal packaging and percutaneous absorption rates for specific compounds also vary among the different races. Reports supporting the occurrence of difference in TEWL, tyrosinase levels, skin elasticity, and water absorption rates between blacks and whites, and reaction to skin irritation have been conflicting. No significant differences in corneocyte size, skin thickness, and skin biomechanics have been reported.  相似文献
