Post-Transplant Lymphoproliferative Disorders Occurring After Renal Transplantation in Adults: Report of 230 Cases From the French Registry

Post-transplant lymphoproliferative disorders (PTLD) are a rare but serious complication after organ transplantation. A French Registry of PTLD was set up in a nationwide population of kidney transplant recipients. We prospectively enrolled all adult kidney recipients developing PTLD between January 1, 1998, and December 31, 2003. We analyzed the incidence, risk and prognostic factors of PTLD by Kaplan-Meier and Cox analyses. Totally 230 cases of PTLD were referred to the French Registry. Cumulative incidence was 1.18% after 5 years. Older age (per year, AHR = 2.19, CI = 1.22-3.94) and recipient Epstein-Barr virus seronegativity (AHR = 3.01, CI = 1.57-5.08) were associated with an increased risk of PTLD. Patients with PTLD had a reduced survival rate (61% at 5 years). Graft PTLD had the best prognosis with an 81% survival rate after 5 years. Infection with hepatitis C or B virus (HCV or HBV), late-onset PTLD, multiple sites involvement and high Ann Arbor staging were risk factors for patient death. Use of azathioprine was associated with a poorer survival rate. PTLD incidence and risk factors in French recipients are in line with the international or American PTLD series. We highlighted the role of HBV or HCV in patient mortality and described the relevant prognosis factors for patients with post-transplant lymphoproliferations.     

Closed suction drainage after orthopaedic surgery: evidence versus practice

Abstract Closed suction drainage systems are commonly used in orthopaedic surgery, particularly in joint arthroplasty. The rationale for the use of drains is a theoretical reduction of wound haematomas and infection. However the benefit of using drains after total hip or knee arthroplasty is controversial. Several reports have shown that the use of drains does not reduce infection and morbidity and is an unnecessary and potentially dangerous practice. In fact most studies highlighted that at best their use appears to make no difference to important clinical outcomes. Recently a metaanalysis raised the question about the usefulness of closed suction drainage again, concluding that it has no major benefits. The purpose of this study was to review the evidences available concerning the utility of closed suction drainage outlining that this practice is not supported by clinical evidence.     

轻、中度精神发育迟滞儿童的中药和行为干预综合治疗探讨

采用中药与行为干预综合治疗的方法对１４０名轻、中度精神发育迟滞的儿童进行分组康复观察。结果发现中药加行为干预组治疗后智力商数（ＩＱ）及能力的变化最大，明显优于单用中药组和单纯行为干预组（Ｐ＜０．０１）；与对照组相比有非常显著的差异（Ｐ＜０．００１）。从而为精神发育迟滞儿童的康复治疗提供了新的途径。     

自行下体负压训练器的研制

目的 研制一种自行下体负压训练器。方法 自行下体负压训练器由若干环形钢圈及涂胶布材料构成的密闭完整的空腔壳体，可上下随意伸缩。上表面安装有单向排气阀门、可调进气阀门、把手及肩带。沿筒体纵轴进行屈／伸膝关节运动，使之被动扩张产生负压。结果 进气阀门完全关闭、打开1／4、1／2至完全打开时，训练器负压峰值逐渐降低，分别为-58、-46、-38和-26mmHg。结论 自行下体负压训练器集体育锻炼和下体负压于一体，安全可靠，使用方便，可望应用于对抗失重生理影响和飞行员抗荷生理训练。     

再生医学技术在烧伤传统治疗无效病人中的应用(附38例报告)

目的：总结重度烧伤传统疗法无效改为再生医学(MEBT/MEB0)技术治疗变化规律和临床验．方法：将我科l995年5月至2002年5月收治的院外采用传统疗法无效改用MEBT/MEBO技术治疗的38例重度烧伤病人临床资料进行回顾性总结，病人一旦入院创面均改用MEBT/MEBO治疗，初始予以彻底清创，规范用药、规范操作，规范认识；全身实行系统综合治疗措施．以临床观察和病人感觉评价治疗效果。结果：本组38例全部治愈，末植皮自行愈合者21例．占55.26％．深Ⅲ度创面自愿要求植皮者17例，占44.74％。经随访多数无增生性瘢痕，部分愈后有局限性瘢癌，质软无残废。结论：重度烧伤经传统疗法久治不愈或疗效欠佳病人．病情复杂，并发症较多治疗难度也较大，再生医学可有效改善以上缺陷和病症．是重度烧伤病人传统治疗无效时的理想疗法。     

Stochastic models for geriatric in-patient behaviour

Departments of geriatric medicine engage in two distinct formsof clinical activity: acute/rehabilitative and long-stay care.These are organizationally distinct and have very differentresource needs. Current hospital planning models, however, assumethat patients all move through the system at the same rate,thereby ignoring this effect of inherent heterogeneity in patientbehaviour. The present paper describes the movement of patientsthrough geriatric hospitals by a two-stage continuous-time Markovmodel, where the stages represent acute/rehabilitative and long-staypatients respectively. Patients are initially admitted to thefirst stage, from which they may depart from the system, bydeath or discharge, or move into the second stage, from whichthey eventually depart by death or discharge (unlikely). Admissionsare modelled in two ways: either as replacements for departuresor as a Poisson stream. Expressions for the distribution andmovement of numbers of patients are derived and evaluated fordata from a number of hospitals. Such an approach has the advantage,over previous crude models, of taking into account differenttypes of patients and introducing variability, thus making itpossible to extract variances as well as means of numbers ofgeriatric patients requiring hospital care.     

Additive effects of earthworm extract with HpD-laser on the enhancement of reactive oxygen production and the inhibition of[~3H]—thymidine.uptake in mouse ascitic tumor cells

The effects of combined use of earthworm extract(912)and HpD-laser on the produc-tion of reactive oxygen and the biosynthesis of DNA in S_(180) tumor cells were studied throughchemiluminescence measurement and[~3H]-TdR incorporation assay.The results showed that as com-pared with the control,the intensity of chemiluminescence emitted by tumor cells treatedsimultaneously with 912 and HpD-laser was enhanced more than ten-folds,while that treated with912 or HpD-laser alone was increased only 2～4 folds.The[~3H]-TdR incorporation into tumorcells of the former group was inhibited upto 74.1%,and that of the latter groups decreased onlyby 42.2% and 40.0%,respectively.In accordance with these biochemical changes,the ultrastructuraldamage of tumor cells of the former,combinedly treated group appeared to be the most serious.This suggests an additive effect of 912 with HpD-laser on tumor cells.In addition,if free radicalscavengers,such as catalase and superoxide dismutase,were added to the reaction systembefore chemiluminescence assay,the luminescent enhancement effect mentioned above was dramaticallyalleviated,implying the presence of O_2~ and H_2O_2 in the system.Therefore,as to the toxic effecton tumor cells,912 and HpD-laser are not only additive in efficiency,but also similar in theunderlying mechanism of action.
