TURP治疗巨大前列腺增生症的体会(附41例报告)

目的探讨巨大良性前列增生症(benignprostatichyperplasia,BPH)的治疗方法。方法回顾性分析41例巨大的BPH患者采用经尿道前列切除术(transurethralresectionoftheprostate,TURP)治疗的临床资料。结果TURP后,前列腺症状评分(internationalprostatesymptomscore,IPSS)由术前平均30±2郾5分,降至术后8郾1±2郾5分;最大尿流率由术前平均(5郾1±2郾4)ml/s升至术后平均(18郾6±5郾3)ml/s;剩余尿由术前50～1100ml降至术后0～40ml。手术并发症5例(12郾3%),其中前列腺电切综合征(transurethralresectionsyndrome,TURS)3例,继发出血2例。结论在熟练掌握TURP技术后,用TURP治疗巨大BPH是一种相对安全、并发症少、疗效好的方法。     

肠康复治疗和短肠综合征

目的探讨对短肠综合征患者进行肠康复治疗的策略。方法采用文献复习的方法对肠康复治疗在短肠综合征患者中的应用加以综述。结果肠康复治疗是指重建肠道功能从而摆脱肠外营养的过程,通常包括膳食和内科保守治疗手段,有时还包括外科治疗。最近的研究显示,药物治疗、特需营养素、生长因子等的使用促进了肠代偿和吸收功能。结论肠康复治疗有益于短肠综合征患者的恢复,并将发挥更重要的作用。     

Acute encephalopathy associated with influenza and other viral infections

Acute encephalopathy is the most serious complication of pediatric viral infections, such as influenza and exanthem subitum. It occurs worldwide, but is most prevalent in East Asia, and every year several hundreds of Japanese children are affected by influenza-associated encephalopathy. Mortality has recently declined, but is still high. Many survivors are left with motor and intellectual disabilities, and some with epilepsy. This article reviews various syndromes of acute encephalopathy by classifying them into three major categories. The first group caused by metabolic derangement consists of various inherited metabolic disorders and the classical Reye syndrome. Salicylate is a risk factor of the latter condition. The second group, characterized by a systemic cytokine storm and vasogenic brain edema, includes Reye-like syndrome, hemorrhagic shock and encephalopathy syndrome, and acute necrotizing encephalopathy. Non-steroidal anti-inflammatory drugs, such as diclofenac sodium and mephenamic acid, may aggravate these syndromes. Severe cases are complicated by multiple organ failure and disseminated intravascular coagulation. Mortality is high, although methylprednisolone pulse therapy may be beneficial in some cases. The third group, characterized by localized edema of the cerebral cortex, has recently been termed acute encephalopathy with febrile convulsive status epilepticus, and includes hemiconvulsion-hemiplegia syndrome and acute infantile encephalopathy predominantly affecting the frontal lobes. Theophylline is a risk factor of these syndromes. The pathogenesis is yet to be clarified, but an increasing body of evidence points to excitotoxicity and delayed neuronal death.     

Treatment of calcaneal fractures: the available evidence

Abstract Calcaneal fracture is the most common of the tarsal fractures and represents 1%–2% of all fractures. The fractures may be divided into extra-articular (not affecting the joint) and intra-articular (involving the talo-calcaneal and calcaneal cuboid joints) types. The management of heel fractures includes nonoperative and operative treatments, but no clear consensus has been reached. The choice of operative treatment is still controversial with many factors influencing the final clinical outcome. Many studies have assessed the outcome of treatment of calcaneal fractures, but there is a general disagreement on their management. The objective of this study was to collect and evaluate the scientific evidence reported in the literature supporting the different treatments for calcaneal fractures.     

地震伤中小腿开放性骨折的特点及治疗经验

四川汶川发生里氏8.0级地震后,第二军医大学第七医疗队于5月15日凌晨抵达重灾区江油市,至7月7日离开54d中,共处理开放性胫腓骨骨折43例.山于地震伤在不同时期、不同震级、不同地理环境及建筑物条件下都有其不同的特点,加上胫腓骨开放性骨折的高致残率(截肢、感染、肢体短缩)在地震伤中的高发生率[1],故将这43例的病例特点及我们的救治体会总结如下.     

二甲双胍在多囊卵巢综合征的作用

生殖及代谢异常是多囊卵巢综合征(PCOS)的特征性表现。已证实高胰岛素血症及胰岛素抵抗,导致血中雄激素水平过高,是PCOS的重要发病机制。二甲双胍(metformin)称为胰岛素增敏剂,用于治疗PCOS后,可减轻高雄激素血症,使月经周期规律,改善卵巢对诱导排卵的反应,提高妊娠率,降低早孕流产率,且能减低发展为II型糖尿病及心血管疾病的危险性。本文就国外近年有关metformin运用于PCOS的进展作一综述。
