The implantable cardioverter defibrillator:the end of the thoracotomy approach

Internal cardioverter defibrillator (ICD) implantation has become a standard therapy for life-threatening arrhythmias. A simple and safe surgical implantation technique is therefore mandatory in this high risk population. In a 30-month period 86 patients received 87 ICD devices. An endocavitary lead system was used as first choice in 62 patients and defibrillation thresholds (DFT) of 25 joules (J) or less were obtained in 57 patients. A thoracotomy approach was avoided using a biphasic shock wave form in 17 patients and the addition of a subcutaneous (sc) patch in 11 patients or wire array lead in 9 patients. There was one early non-technique related death (1.7%) after the transvenous approach. Reoperation was necessary in three patients with lead complications and in two patients for local device problems (one migration, one infection). With the recent progress in ICD technology, a thoracotomy approach could be avoided for the last 52 patients. For comfort and cosmetic reasons left subcostal insertion of the device has been successfully used in the last 50 patients. We conclude that the nonthoracotomy approach can now be offered to all patients in need for an ICD as a consequence of the technological progress made in the field of electric treatment of malignant ventricular arrhythmias. A stepwise approach with a minimum of implanted hardware and the use of biphasic shock systems now offers a simple and efficient treatment alternative with very low perioperative risk. Internal cardioverter defibrillator implantation in combination with open heart procedures can easily be avoided.     

Papillary thyroid cancer and its surgical management.

The surgical management in papillary thyroid cancer has been highly controversial. In the Department of Surgery (II), Kanazawa University Hospital, the surgical management especially for cervical lymph node metastases has changed since 1973 from a conservative approach to an aggressive one. In order to determine whether an aggressive approach is warranted, a retrospective multivariate analysis was carried out on 106 cases of papillary thyroid cancer. The patients have been followed for 10-28 years. Multivariate analysis was conducted following Cox's model. By this analysis, aggressive management appeared to have no impact on survival or relapse-free survival. However, age, sex, tumor size, and cervical lymphadenopathy were confirmed to be important prognostic factors in survival and/or relapse-free survival.     

OCM入路微创全髋关节置换术的初步报告

目的介绍OCM入路微创全髋关节置换术(THA)的手术方法。方法2005年1月-2006年1月在对2具尸体、4个髋关节的OCM入路进行相关解剖学研究的基础上开展OCM入路微创THA 20例。手术从臀中肌前间隙进入切开关节囊,分段完成股骨颈截骨,使用特殊的髋臼锉和髋臼打入器安放髋臼假体;股骨侧手术时手术床后下方一半拆卸掉,患髋后伸和外旋且小腿置于消毒袋内,大转子周围关节囊广泛剥离后完成扩髓和股骨假体的安放。结果肥胖指数平均为27．4％的20例患者,皮肤切口长度平均为9．3 cm;术中平均出血130 mL,术后引流量80 mL;患者术后2-3 d下地活动。所有患者获得1-9个月(平均4．3个月)随访,15例已完全脱拐,行走正常;5例不满1个月,仍需扶拐行走。术后随访疼痛采用视觉模拟评分(VAS)由术前平均5．1分分别下降到3．6分(1个月)、1．7分(3个月)和0．8分(6个月)。发生血肿2例,X线检查见髋臼前倾过大2例,股骨假体型号偏小2例。患者髋关节功能Harris评分由术前平均45．4分提高到术后随访时平均88．4分。结论OCM入路微创THA切口小,完整保留臀中肌和关节囊,患者功能恢复快,住院时间短;它需要一个独立学习过程,并需要特殊器械的配合。     

示范区创建活动与社区卫生服务长效机制的建立和可持续发展对策的思考

通过第三方评估全国社区卫生服务示范区是我国社区卫生服务发展史上的一大创举。此项活动的开展,极大的提高了各地政府对发展社区卫生服务的思想认识、政策理解和经费投入力度。通过创建和评估活动,系统总结了各申报地区社区卫生服务的经验和特色,分析了存在的问题和不足,提出了发展社区卫生服务的对策和建议,制定了社区卫生服务可持续发展的长效机制,取得了预期效果,达到了预期目的。随着《国务院关于发展城市社区卫生服务的指导意见》的出台,示范区的典型示范效应会日益凸显出来,对我国社区卫生服务的发展将起到不可估量的作用。

Interhemispheric multiloculated ependymal cyst with dysgenesis of the corpus callosum: a case in a preterm fetus

Introduction The authors report a case of interhemispheric ependymal cyst accompanied with agenesis of the corpus callosum in a fetus. Discussion Routine ultrasound and subsequent magnetic resonance imaging of a 20-year-old woman at 33 weeks and 1 day of gestation detected a large interhemispheric cystic lesion in the fetal cranial cavity. Caesarian section was carried out at 36 weeks because of the progressive enlargement of the fetal head. The cyst was multiloculated and a cyst peritoneal shunt placement resulted in collapse of the drained cyst components followed by enlargement of others. After wrack-a-mole-like shunt revisions, open surgery was performed at the age of 2 years. Cyst walls were fenestrated and the cavities were communicated with each other and eventually with the lateral ventricle. Pathological diagnosis of the cyst wall was ependymal cyst. The boy is now 3 years old, and growing without apparent developmental delay or recurrence. Current concept and management policy of the interhemispheric cyst accompanied with agenesis of the corpus callosum is reviewed.
