Arthroscopic Coracoclavicular Ligament Reconstruction Using Biologic and Suture Fixation

Presented in this report is a modified arthroscopic approach to acromioclavicular joint reconstruction via suture and allograft fixation. An arthroscopic approach is used to expose the base of the coracoid by use of electrocautery. After an open distal clavicle excision is performed, clavicular and coracoid tunnels are created under arthroscopic visualization as previously described by Wolf and Pennington. The myotendinous end of a semitendinosus allograft is sutured to a Spider plate (Kinetikos Medical, San Diego, CA). The tendinous end of the graft is prepared with a running baseball stitch. A Nitinol wire with a loop end (Arthrex, Naples, FL) is used to pass 2 free FiberTape sutures (Arthrex) and the leading sutures from the tendinous end of the graft through the clavicular and coracoid tunnels, exiting out the anterior portal. One of the FiberTape sutures is retrieved with a grasper and passed over the anterior aspect of the distal clavicle. The second FiberTape suture and the allograft are passed over the distal end of the resected clavicle. While the acromioclavicular joint is held reduced, the FiberTape sutures are tied to the plate and the allograft is tensioned medially until the plate is embedded against the superior surface of the clavicle. The tendinous end of the graft is secured to the superior surface of the clavicle with a Bio-tenodesis screw (Arthrex) medial to the clavicular tunnel.     

胆道癌ERCP诊断(附49例分析)

本文报道用ERCP诊断胆管癌24例、胆囊癌6例、壶腹癌19例、共49例,都经手术或病理证实,诊断符合率为85.7％。 文章描述了胆道癌ERCP的X线表现。依造影所见把胆管癌分为阻塞型、狭窄型和息肉型。狭窄型又分闭塞型、环型及弥漫型三个亚型。胆管癌以阻塞型和闭塞型狭窄多见。胆囊癌表现为胆囊内基底宽广固定不变的充盈缺损。壶腹癌为壶腹部边缘不整的占位病变,可阻塞胆管或胰管或同时阻塞胰胆管。肝内胆管的软藤状改变是胆道恶性肿瘤的特征性表现。     

加替沙星序贯治疗下呼吸道细菌感染的药物经济学评价

目的对加替沙星序贯治疗下呼吸道细菌感染进行药物经济学评价。方法将69例下呼吸道细菌性感染患者，随机分为A组（34例）、B组（35例），其中A组采用加替沙星注射液400mg静脉滴注，每天1次，连用10天；B组先用加替沙星注射液400mg静脉滴注，每天1次，3—4天后改为口服400mg，每天1次，连用6—7天，然后对两种方案进行成本-效果分析。结果两组在临床疗效、不良反应发生率及细菌清除率方面差异无统计学意义（P〉0．05）；但A组的医疗费用却高于B组（P〈0．01）。结论加替沙星序贯疗法与单纯静脉滴注相比更安全，更经济合理。     

Concomitant mitral valve repair and left ventricular reconstruction in a patient with chronic ischemic mitral regurgitation and inferior left ventricular aneurysm

The surgical approach to ischemic mitral regurgitation with concomitant inferior left ventricular aneurysm remains uncertain in terms of the indication for operation and the short-and long-term outcomes. We performed concomitant mitral valve repair, left ventricular reconstruction, and aortic valve replacement on a 71-year-old male with severe ischemic mitral regurgitation, inferior left ventricular aneurysm, and degenerative aortic regurgitation. Postoperative status was in New York Heart Association functional class I without mitral regurgitation 8 months after operation. We discuss, and review the procedures reported in the literature.     

机械通气患者的呼吸道护理

目的：探讨机械通气患者呼吸道的护理以及并发症的预防；方法：查阅有关机械通气护理的文献；结果：呼吸衰竭患者在使用机械通气治疗的过程中护理不当可引起呼吸机相关肺炎、气管阻塞、气管损伤、低氧血症等；结论：加强机械通气患者的呼吸道护理可避免呼吸道并发症的发生。     

儿童呼吸道苛养菌分离培养及药敏分析

目的：分析儿童呼吸道苛养菌的感染率及常用抗生素的耐药状况。方法：采用儿童呼吸道2050份咽拭子及痰标本进行苛养菌分离培养与鉴定，并对其中617株苛养菌做了药敏试验，结果：显示275株肺炎链球菌，耐药率较高的有红霉素81.1%，苯唑西林76.9%，复方磺胺甲恶唑76.9%，四环素65.4%；104株流感嗜血杆菌、184株副流感嗜血杆菌、54株卡他莫拉菌对氨苄西林耐药率分别为17.6%,28.9%,64.9%，对亚胺培南/西司他丁耐药率分别为16.4%，16.5%，0，同时复方磺胺甲恶唑的耐药率也分别高达56.7%，56.7%，64.9%。结论：提示苛养菌在儿童呼吸道感染中占有重要的地位，及时掌握这类细菌的耐药动态，对合理使用抗生素，延缓耐药株的产生有极其重要的临床意义。     

首例中国可视化人体心脏三维重建及临床意义

目的 对首例中国数字化可视人体的心脏进行三维重建，为心脏疾病的影像学诊断和外科手术提供三维解剖学依据。方法 将首例中国数字化可视人体心脏部分的薄层断面(层厚1．0mm)输入SGI工作站，经数据分割、对位重建、平滑处理和三维显示等步骤，完成对心脏结构的三维重建。结果 本研究完整地重建出了心脏结构，重建的结构能够以多结构、多彩色实体模型方式显示，可显示心脏内部各结构的空间位置和毗邻关系，可在三维空间伴置上绕任意轴旋转任意角度。结论 重建出的三维图像清晰地显示了心脏内部和整体的结构，实现了心脏的二维可视化。     

矢状缝早闭(舟状头)全颅成形术

目的探讨治疗矢状缝早闭(舟状头)畸形的手术方法。方法采用David“‖”形颅缝重建法(6例)、旋转骨瓣截骨法(2例)、梅花颅骨瓣头颅盖成型法(3例)等术式对舟状头进行矫治。结果11例患儿均治愈,外形满意。结论1~3个月舟状头宜采用简单的David“‖”形颅缝重建法进行治疗,3个月以上的患儿可选用浮动颅骨瓣头颅成型术、梅花瓣法颅骨瓣头颅盖成型术等方法进行治疗。
