Dermatofibrosarcoma protuberans: a population-based cancer registry descriptive study of 66 consecutive cases diagnosed between 1982 and 2002

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a rare malignant tumour of the skin, with an estimated incidence of 0.8 to five cases per 1 million people per year. OBJECTIVE: To study epidemiological, immunohistochemical and clinical features, delay in diagnosis, type of treatment and outcome of DFSP from 1982 to 2002. METHODS: Using data from the population-based cancer registry, 66 patients with pathologically proved DFSP were included (fibrosarcomatous DFSP were excluded). Each patient lived in one of the four departments of Franche-Comté (overall population of 1 million people) at the time of diagnosis. The main data sources came from public and private pathology laboratories and medical records. The rules of the International Agency for Research on Cancer were applied. RESULTS: The estimated incidence of DFSP in Franche-Comté was about three new cases per 1 million people per year. Male patients were affected 1.2 times as often as female patients were. The trunk (45%) followed by the proximal extremities (38%) were the most frequent locations. DFSP occurred mainly in young adults between 20 and 39 years of age. Mean age at diagnosis was 43 years, and the mean delay in diagnosis was 10.08 years. Our 66 patients initially underwent a radical local excision. Among them, 27% experienced one or more local recurrences during 9.6 years of follow-up. There was one regional lymph node recurrence without visceral metastases. These recurrences were significantly related to the initial peripheral resection margins. We observed a local recurrence rate of 47% for margins less than 3 cm, vs. only 7% for margins ranging from 3 to 5 cm [P=0.004; OR=0.229 (95%, CI=0.103-0.510)]. The mean time to a first local recurrence was 2.65 years. Nevertheless, there was no death due to the DFSP course at the end of the follow-up, and the final outcome was favourable. CONCLUSION: Our study emphasizes the importance of wide local excision with margins of at least 3 cm in order to prevent local recurrence. However, the recent development of inhibitors of signal transduction by the PDGFB pathway should soon modify the surgical strategy, which is often too mutilating.     

重症急性胰腺炎102例临床分析

目的探讨重症急性胰腺炎的合理治疗方案。方法以1985年1月～2005年8月间收治的102例重症急性胰腺炎作研究对象，比较手术组与非手术组的主要并发症和死亡率。A组：1985年1月～1993年12月以手术治疗为主41例；B组：1994年1月～2005年8月以早期非手术治疗为主61例。结果手术组死亡率和并发症发生率明显高于非手术组，两组病死率及并发症发生率比较差异有显著性（P〈0．05）。结论重症急性胰腺炎采用早期非手术治疗能有效降低病死率和并发症发生率。大多数重症急性胰腺炎可经非手术治愈。     

Development of autoimmune hepatitis in primary biliary cirrhosis.

AIM/BACKGROUND: Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease of unknown aetiology. Up to 10% of patients with typical features of PBC will have additional features of autoimmune hepatitis (AIH). A subset, however, have no such features but go on to develop a 'sequential' AIH overlap syndrome. Objectives: Describe our experience with eight patients who developed AIH after the diagnosis of PBC was made. METHODS: We reviewed the charts of all PBC patients over a 9-year period (from 1996 to 2005). Only PBC patients with no features of AIH were included. RESULTS: There were 1476 patients with PBC. Of these, eight patients developed features of AIH overlap syndrome based on biochemical and histological parameters. Treatment included prednisone and azathioprine for 24 or more months. The majority of patients remained on ursodeoxycholic acid (UDCA) throughout treatment. Response to therapy was defined by improvement in enzymes, and was rapid for all patients. One patient was able to discontinue treatment with prednisone and azathioprine, while seven have continued on therapy to date. CONCLUSIONS: A 'sequential' overlap syndrome of AIH with PBC can occur. Treatment with prednisone and azathioprine may lead to a rapid improvement in aminotransferase levels.     

医改尚未成功,路在何方?

目前我国医疗制度改革尚未取得成功,这与计划经济向市场经济转轨这历史时期及卫生工作的特殊性有关,出现问题,甚至失误,在所难免。提出(1)医改的目的是确保全国人民健康,人人享有医疗保健。(2)把卫生系统推向市场,医疗机构商业化,不是医改的方向。(3)预防为主,健全预防医学制系。(4)国家增加投入。(5)制定公立及私立医院各项制度,保护医务人员的合法权益。(6)加强社区基层医疗机构的建设。     

皮瓣展平法在耳廓再造时扩张皮瓣感染中的应用

目的探索耳廓再造时扩张皮瓣感染的处理方法。方法分析中国协和医科大学整形外科医院外耳冉造中心2003年1月～2005年12月耳廓再造时耳后扩张皮瓣发生感染，经皮瓣展平法处理，感染控制后进行耳再造的12例（12耳）患者的治疗情况。结果12例（12耳）患者手术顺利，术后恢复好，再造耳效果与无感染者无明显差异。结论皮瓣展平法是耳廓再造时扩张皮瓣感染较理想的处理方法。

A Call for a National Transplant Surgical Quality Improvement Program

The severity of illness in transplant patients and the complexity of transplant operations results in significant postoperative morbidity and mortality. Remarkable efforts have been made by transplant physicians to study and improve organ allocation, graft and patient survival, immunosuppression and the long-term management of post-transplant complications. Less effort has been spent studying the actual transplant operation and systems of acute transplant care. The National Surgical Quality Improvement Program (NSQIP) has provided a standardized approach to quality improvement and has demonstrated significant potential for a reduction in postoperative morbidity and mortality in other surgical disciplines. Medical centers are under increasing pressure to measure surgical quality and the nexus of transplant surgical quality improvement should not lie in the hands of CMS or JACHO, but rather it should be created and developed within the transplant community. The time has come for a national transplant surgical quality improvement program based on the NSQIP infrastructure. Such a proactive approach toward quality improvement from the transplant community is an excellent investment for patients, providers and health care payers.     

神经症患者主客观生活事件的影响因素

目的研究应对方式、社会支持和压力反应等与应激有关因素对神经症患者主观、客观生活事件的影响。方法应用自编生活事件量表、压力反应问卷、特质应对问卷、领悟社会支持量表及一般情况调查表对88例神经症患者和88名健康对照进行调查和分析。结果神经症组主观事件得分[(13.295±11.845)分]高于健康组[(7.261±10.873)分](P<0.01),而神经症组客观事件得分[(10.239±9.105)分]与健康组得分[(8.376±11.213)分]差异无显著性(P>0.05)。神经症组主观事件与压力反应正相关,与家庭内支持和年龄负相关(P<0.01),客观生活事件与应激其他因素均无关;健康对照组主观事件与压力反应正相关,客观生活事件与压力反应和消极应对正相关(P<0.01)。多元逐步回归分析提示,影响神经症组主观事件的因素依次有客观事件、年龄、压力反应和家庭内支持,预测力为47.7%;但影响神经症组客观事件、健康组主观事件和客观事件的仅有相对应的主观或客观事件。结论神经症患者主观事件报告明显多于健康人群,且神经症患者主观事件受其他压力有关因素的影响较大。
