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。     

胆囊结石伴胆囊癌的诊治分析

目的探讨胆囊癌与胆囊结石的关系及胆囊结石伴胆囊癌的诊断和治疗特点。方法对1993年1月至2004年12月间收治的27例胆囊癌合并胆囊结石患者进行回顾性临床分析。结果27例胆囊癌合并胆囊结石患者,男10例,女17例,男女之比为1:1.7。平均年龄68.5岁,其中60岁以上22例。临床症状最常见为腹痛(85.2%)。既往有明确胆结石病史患者15例,入院后发现胆结石的有12例。行B超检查的23例,诊断胆囊癌的有12例(52.2%)。CT结合增强扫描检查12例,诊断胆囊癌的有8例(66.7%)。行肿瘤根治切除者8例,根治率29.6%。随访13例,随访期为3个月~7年,获随访者的平均存活时间为12个月。结论胆囊结石是胆囊癌的发病因素之一,胆囊癌早期诊断困难,晚期治疗效果差,伴胆囊结石的胆囊癌关键是要引起重视,不能满足胆囊结石的诊断而遗漏胆囊癌。对胆囊结石患者要密切随访,高危患者要尽早手术。     

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.     

从天价医药费事件折射出当前我国医疗机构存在的问题

目前，我国许多医院的医疗卫生工作人员在为患者进行医疗卫生服务的过程中，为了医院和个人的经济利益，存在着过度医疗消费现象。最典型的是哈尔滨医科大学第二附属医院发生的天价医药费事件。导致这种现象出现的原因是由于法律的不健全、制度的不完善等而导致的监督力度不够，加之有些医务工作者在经济利益的驱使下使自己的职业道德滑坡，从而导致了老百姓看病贵现象的出现。     

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。     

The value of a pantaloon cast test in surgical decision making for chronic low back pain patients: a systematic review of the literature supplemented with a prospective cohort study

The results of lumbar fusion in chronic low back pain (LBP) patients vary considerably, and there is a need for proper patient selection. Lumbosacral orthoses have been widely used to predict outcome, however, with little scientific support. The aim of the present study was to determine the value of a pantaloon cast test in selecting chronic LBP patients for lumbar fusion or conservative management. First, a systematic review of the literature was carried out in which two independent reviewers identified studies in Medline, Cochrane and Current Contents databases. Three papers met the selection criteria. In the only study with a control group, a significantly better outcome after fusion compared to conservative treatment was found in patients who reported significant pain relief while in a cast (i.e. a positive cast test). The results of lumbar fusion, however, were not significantly different for patients with a positive and those with a negative cast test. In addition to the review, a clinical cohort study of 257 LBP patients, who had been allocated to either lumbar fusion or conservative management by a temporary external transpedicular fixation trial, was performed. Prior to allocation, all had undergone a pantaloon cast test. Patients with no history of prior spine surgery and with a positive pantaloon cast test had a better outcome after lumbar fusion than those treated conservatively (P = 0.002, χ ² test). In patients with previous spine operations the outcomes were poor and the test was of no value. From the literature and the present patient cohort, it was concluded that only in chronic LBP patients without prior spine surgery, a pantaloon cast test with substantial pain relief suggests a favorable outcome of lumbar fusion compared to conservative management. The test has no value in patients who have had previous spine surgery.     

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。     

Outcome of conservative treatment of primary vesicoureteral reflux in 87 Thai children in a single center

AIM: To evaluate the outcome of primary vesicoureteral reflux (VUR) using conservative treatment. METHODS: Eighty-seven children with primary VUR who had been treated with a conservative medical regimen and monitored through a yearly cystogram were recruited for the study. The study was conducted at the Pediatric Nephrology Clinic in Songklanagarind Hospital, the major tertiary care center in southern Thailand. Statistical analyses using Kaplan-Meier survival curves, chi-squared test, Fisher's exact test and multivariate analysis with Cox regression were performed. RESULTS: The study group consisted of 41 boys and 46 girls, with a total of 133 VUR. The age of the boys was significantly lower than that of the girls (P < 0.001). Resolution of the low grades (grades I-III) of VUR was significantly more frequent than that of the high grades (grades IV-V) (68/95, 72%vs 14/38, 37%; P < 0.001). Using the Kaplan-Meier survival analysis and log-rank test, the resolutions of VUR in boys versus girls, and age <1 years versus >or=1 years were not significantly different (P = 0.2252 and 0.4756, respectively). Low-grade VUR and unilateral VUR had significantly higher probabilities of resolution than high-grade VUR and bilateral VUR, respectively (P = 0.0041 and 0.0467, respectively). Multivariate Cox regression analysis indicated that among low-grade VUR, boys and unilateral VUR had significantly higher probabilities of resolution. Among the high-grade VUR, neither sex nor laterality had a significant effect on the probabilities of VUR resolution. CONCLUSION: This study offers more evidence that children with low-grade VUR have a higher chance of reflux resolution if they are boys and have only unilateral VUR. There is still no good guide for resolution of reflux in children with high-grade VUR.
