Pathogenesis of ulcerations in deficiency of prolidase. The role of angiopathy and of deposits of amyloid

The structure of the skin and the pattern of alteration in chronic ulcerations associated with deficiency of prolidase have been studied superficially in the past. We examined histologically several biopsies taken from apparently normal skin and from ulcerations afflicting a young woman with such a syndrome. Deposits of amyloid were found within the walls of medium-sized vessels and occasionally occluding their lumens. Impaired cutaneous microcirculation resulting from statis, moderate vasculitis, and abnormal structure of the dermis may be responsible for the regional preponderance of deposits of amyloid and ulcerations in the legs.

243例太田痣临床分析

目的 对湖北及周边地区太田痣患者进行临床分析.方法 回顾分析243例太田痣患者在发病时间、色素性疾病家族史及患者母亲妊娠期间是否有用药史等方面进行统计学比较.结果 太田痣出生时发病者占58.0%,出生后发病者占42.0%,主要集中于5～15岁.有色素性疾病家族史者占60.1%,其中以雀斑和咖啡斑为主.患有太田痣与女性妊娠期间是否有用药史无明显关系.结论 太田痣可能具有遗传性,具有色素性疾病史的患者,其后代患太田痣的可能性较大.     

综合疗法治疗复发性念珠菌性包皮龟头炎

目的探讨口服氟康唑胶囊、外用曲安奈德益康唑乳膏联合包皮环切术防治复发性念珠菌包皮龟头炎的疗效。方法采用随机分组法,治疗组(46例)给予氟康唑胶囊200mg,1次/d,连服3d,外用曲安奈德益康唑乳膏,早、晚各1次,2周为1个疗程,炎症控制后行包皮环切术。对照组(40例)给予氟康唑胶囊连服6d,曲安奈德益康唑乳膏外用2周。治疗后2周及2,4和6个月时随访。结果 2周后,两组痊愈率分别为89.13%和85.00%,差异无统计学意义(P>0.05)。两组有效率分别为100.00%和95.00%,差异无统计学意义(P>0.05)。2,4,6个月治疗组复发率分别为4.88%,9.76%和9.76%,对照组复发率分别为23.53%,38.24%和50.00%,两组比较差异均有统计学意义(P均<0.05)。结论综合疗法治疗复发性念珠菌包皮龟头炎安全有效,并能有效减少复发。     

Method of histological control of the edges of surgical specimens of basal cell epitheliomas

For histologic control of excisional margins, routinely fixed tumor specimens or under certain conditions, specimens fixed immediately in warm formalin are processed in the histology laboratory. Strips are then cut from the undersurface, edge and cross section of the specimen and processed further by routine paraffin techniques until HE-stained sections of the entire periphery and midsection are available. The average follow-up time was of 4 years with a recurrence rate of 0.4 per cent.     

红皮病120例病因分析

目的：探讨红皮病的病因及并发感染的情况。方法：回顾性分析120例红皮病患者的临床资料。结果：120例患者中73．3％红皮病继发于原有皮肤病，其他致病原因依次为药物过敏、肿瘤，部分原因不明。28．3％并发感染的红皮病患者中，41～60岁组和〉60岁年龄组的感染率高于≤40岁年龄组，差异有统计学意义（P均〈0．05）；血浆白蛋白降低组患者感染率高于血浆白蛋白正常组患者，差异亦有统计学意义（P〈0．01）。结论：红皮病病因多种多样，不能忽视非常见病因的存在。随着年龄的增长和血浆白蛋白的降低，红皮病患者的感染率增加，应注意皮肤护理及早期支持治疗。     

Epidemiological evidence of carcinogenicity of sunbed use and of efficacy of preventive measures

The International Agency for Research on Cancer classified, in July 2009, exposure to artificial tanning devices (sunbeds) as carcinogenic to humans. This classification was based on evidence from epidemiological and experimental animal studies. The present chapter will review these epidemiological evidences. The summary risk estimates from 27 epidemiological studies obtained through a meta‐analysis showed an increased risk of melanoma: summary relative risk (SRR) = 1.20 [95% confidence interval (CI) 1.08–1.34]. The risk was higher when exposure took place at younger age (SRR = 1.59; 95% CI 1.36–1.85). The risk was independent of skin sensitivity or population and a dose response was evident. A meta‐analysis of 12 studies was conducted for non‐melanoma skin cancers and showed a significantly increased risk for basal cell carcinoma (SRR = 1.29; 95% CI 1.08–1.53) and for squamous cell carcinoma (SRR = 1.67; 95% CI 1.29–2.17). As for melanoma, the risk for other skin cancers increased for first exposures at young age. Epidemiological studies have gradually strengthened the evidence for a causal relationship between indoor tanning and skin cancer and they fit with prior knowledge on relationship between UV exposure and skin cancer. Additionally, several case–control studies provided consistent evidence of a positive association between use of sunbed and ocular melanoma, also with greater risk for first exposures at younger age. Preventive measures based on information on risk or by requiring parental authorization for young users proved to be inefficient in several studies. The significant impact of strong actions or total ban, such as performed in Iceland, or a total ban of sunbed use, as in Brazil or Australian states, needs to be further assessed.
