Toxic epidermal necrolysis; 15 years'' experience in a Dutch burns centre

BACKGROUND: Toxic epidermal necrolysis (TEN) is a severe and potentially fatal drug reaction characterized by an extensive skin rash with blisters and exfoliation, frequently accompanied by mucositis. The wounds caused by TEN are similar to second-degree burns and severe cases may involve large areas of skin loss. OBJECTIVES: Analysis of our results in patients with TEN and evaluation of the variety of therapeutic interventions that has been studied and suggested in TEN. PATIENTS/METHODS: Retrospective analysis of 19 consecutive patients with TEN treated in our burns centre between 1989 and 2004. RESULTS: Immediate withdrawal of any potentially fatal drug, maximum supportive care, and a restricted and tailored antibiotic, medical and surgical treatment regimen confined mortality to 21%, whereas prognosis scores like APACHE II and SCORTEN predicted mortality of 22 and 30%, respectively. A positive contribution of selective digestive decontamination is suggested but has yet to be established. CONCLUSIONS: Because of a potentially fatal outcome, fast referral of a patient suspected of TEN to a specialized centre (mostly a burns unit or specialized dermatology centre) for expert wound management and tailored comprehensive care is strongly advised and contributes to survival.     

女性慢性下腹痛的干预性治疗

1背景 育龄妇女常见慢性下腹痛，可造成身体损害、情绪忧伤及导致巨大的健康服务费用。美国在这方面的花费超过8亿8千万美元（Mathias 1996）。英国全国数据库的一般性诊治资料显示，慢性下腹痛发病率及流行率与偏头痛、背部痛、哮喘发病率相似（Zondervan 1999）。     

消化道肿瘤血浆胃动素测定及其意义

作者报告经病理诊断消化道恶性肿瘤患者30例及手术切除肿瘤患者15例的血浆胃动素水平,并以健康成人31例作为对照。消化道恶性肿瘤的胃动素水平373.4±123.7ng/L,显著高于正常对照组(162.3±52.3ng/L,P<0.001),而消化道恶性肿瘤患者术前及术后胃动素水平无显著差异。消化道恶性肿瘤患者胃动素水平增高的原因可能是肿瘤刺激神经所致。胃癌和结肠癌细胞可产生胃泌素样物质,它可刺激胃动素的释放。     

腰椎间盘突出合并椎管狭窄的手术治疗

报告手术治疗腰椎间盘突出症合并退行性腰椎管狭窄症１０４例。术后随访９０例，随诊时６个月～６年。优良率８６．５％，无腰椎不稳和腰椎滑脱等并发症。为获得优良效果，作者强调在处理椎间盘突出的同时必须彻底解除侧隐窝及神经根管，黄韧带肥厚对神经根的压迫，才能彻底根除症状     

Guidelines for the collection, processing and storage of human bone marrow and peripheral stem cells for transplantation

SUMMARY. There are no current U.K. or international guidelines or regulations covering the production, processing and storage of haemopoietic cells such as to allow their engraftment following myeloablative therapy. This paper seeks to provide such guidelines. It enumerates how quality control and assurance can be applied to this area of transfusion medicine; procedural steps relating to bone marrow harvest on peripheral blood stem cell collection are outlined and recommended doses of nucleated cells suggested for both procedures. General specifications for identification, storage and transportation of bone marrow and peripheral blood stem cells are included and specific laboratory procedures related to the provision of haemopoietic cells for engraftment are outlined. Umbilical cord blood transplants and long-term bone marrow culture are alluded to but these are still in a research phase.     

肺神经内分泌癌的免疫组化与免疫电镜研究

本文应用免疫组化与免疫电镜技术对20例肺神经内分泌癌进行了研究,另6例非神经内分泌癌作为对照。结果表明:嗜铬颗粒蛋白A免疫组化染色19/20例阳性,免疫电镜能够比较特异地标记神经分泌颗粒,具有确诊意义;神经特异性烯醇化酶染色20/20例阳性,非神经内分泌癌3/6例阳性,免疫电镜下无特异性分布,适宜作为诊断的筛选指标;S-100蛋白和5-HT亦可作为诊断之参考。
