Spinal epidural hematoma. Report of a case and review of the literature

We report the case of a thoracic epidural hematoma at the T7-T9 level which occurred after placement of spinal epidural catheter for continuous anaesthesia in acute pancreatitis. The male patient felt a sudden back pain after six days of successful analgesia and became paraplegic 24 hours afterwards. An emergency laminectomy and removal of the hematoma were performed; however, the patient recovered only incompletely.We discuss the clinical signs and symptoms of spinal epidural hematoma as well as its diagnostics and therapy. The controversial views from the literature concernings its etiology are critically reviewed.     

医源性输尿管损伤临床分析

目的探讨医源性输尿管损伤的原因、类型、处理和预防.方法回顾性分析1994年5月～2003年11月13例14侧医源性榆尿管损伤临床资料.结果 1例输尿管内支架管引流、2例输尿管端端吻合内支架管引流、2例松解部分结扎及内支架管引流、7例8侧输尿管膀胱再植术,输尿管均通畅,肾功能均恢复正常,6例尿瘘治愈;1例肾切除.结论规范化操作及输尿管逆行插管对预防医源性输尿管损伤和早期发现输尿管损伤有决定性的作用和帮助;早期与后期诊断有所不同;治疗的目的是恢复输尿管通畅和保护肾功能;后期诊断病例应考虑一次性恢复输尿管通畅,尽可能不作尿流改道.     

Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventioanl radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment' of biliary strictures are discussed.     

医源性子宫内膜异位症的治疗进展

医源性子宫内膜异位症是指由于医学检查或治疗的影响而使子宫内膜异位种植，存活或已有的内膜异位灶进一步发展，近年发病率逐渐上升，原因主要与各种妇产科操作的增多有关，现就医源性子宫内膜异位症的治疗进展作一综述。     

胃镜检查与幽门螺杆菌感染关系的初步探讨

本文用前瞻性连续检测方法，对２６９例患者作胃粘膜ＨＰ检测，且同步对消毒前后的胃镜、有关器械和操作者手套采样，作ＨＰ检测。结果发现，消毒前镜端（含弯曲部）、活检钳、清洁刷、器械管道插口和操作者手套采样标本的ＨＰ阳性率分别达６９．５１％、７３．６０％、８１．６２％、８７．７３％和９７．７２％。目前常规的清洗消毒虽能清除ＨＰ对胃镜的大部分污染，但还存在一些易忽视的环节，这可能在检查中引起医源性感染，应予高度重视。     

The pathology of encephalic arteriovenous malformations treated by prior embolotherapy

Summary A pathologic study was undertaken of seven encephalic arteriovenous malformations, including five resected from one to seven days after balloon embolization, one resected 10 days after embolization with polyvinyl alcohol foam (PVA), and a large mesencephalic AVM in a patient who died eight weeks after a series of embolization procedures with PVA and silicone spheres. AVM's resected 6–7 days following balloon embolization showed focal mural and adventitial inflammatory infiltrates and parenchymal (i.e. non-vascular) necrosis of a large portion of one AVM. The AVM examined 7 days post-balloon embolization showed an intraluminal thrombus containing refractile particles surrounded by foreign body giant cells (FBGC's). The AVM removed 10 days after PVA embolotherapy showed mural and perivascular necrosis with infiltration by polymorphonuclear leukocytes. The single autopsy case showed FBGC's surrounding residual PVA, refractile particles deep within vascular walls, and marked mural thickening of AVM channel walls, changes that may represent a response to previous angionecrosis and inflammation at the time of embolization. These findings, the pathogenesis of which is discussed in detail, may help to explain some of the rare complications of iatrogenic embolotherapy with these materials, as well as providing evidence for the basis of their efficacy.Presented in part at the 63rd Annual meeting of the American Association of Neuropathologists, Seattle, Washington, June, 1987

医源性腓总神经伤分析

目的：总结40a来收治的48例医源性腓总神经损伤的临床资料，探讨其损伤机制和特点。方法：通过随访，依据其损伤原因和机制分类统计。结果：牵拉压迫伤33例，占69％；手术切割伤12例，占25％。导致腓总神经损伤的原因中以石膏压迫为最多，占37％，牵伸性损伤占31％。结论：骨科医师必须具备丰富的解剖知识和责任心，重在预防，一旦发生损伤，应早期诊断，采用有效的方法及时治疗。     

A closer look at iatrogenic hypospadias

Almost all surgical repair techniques for hypospadias include dissection of the glans penis, and covering the neo-urethra with the glans tissue circumferentially. Surprisingly, the presence of the “septum glandis” in the ventral midline has been overlooked for decades. A careful examination of six patients with iatrogenic hypospadias (IH) revealed direct indications of the septum glandis. All patients were treated with long-term urethral catheterisation in the paediatric intensive care unit due to neurologic and/or metabolic diseases. The glans was disrupted in all patients due to ventral midline compression of the urethral catheter, which resulted in a tear in the septum glandis. A remnant of the septum glandis was clearly observed in patients with an incomplete tear. Further injuries caused tear in the frenulum and corpus spongiosum, exposed the glanular urethra and made its vertical elliptical shape, the “fossa navicularis”, visible. Intact contours of the separated glans wings were observed in all patients. The glans wings merge ventrally in the midline, but are separated by a fine connective tissue (septum glandis) in conjunction with the frenulum, which is involved in the formation of the ventral wall of the glanular urethra. IH provides further insight into the structural anatomy of the normal human glans and glanular urethra.     

British Association of Urological Surgeons (BAUS) consensus document: management of bladder and ureteric injury

Injuries to the bladder and ureter are uncommon but usually require prompt urological management. Due to their infrequent nature, Urologists maybe unfamiliar with managing these acute problems and may not work in specialist centres with readily available expertise in open and abdominal surgery. We aim to provide advice in the form of a consensus statement led by the Female, Neurological and Urodynamic Urology (FNUU) Section of the British Association of Urological Surgeons (BAUS), in consultation with BAUS members and consultants working in units throughout the UK, to create a comprehensive management pathway and a series of statements to aid clinicians.
