Statistical analysis of pathologic risk factors for intramyometrial lymphvascular space involvement in myoinvasive endometrial carcinoma

In a retrospective study using univariate analysis, we identified tumor type (nonendometrioid vs endometrioid), depth of myoinvasion (MI), mode of MI (infiltrative vs cohesive), and direct anatomic invasion of the cervical wall from the isthmus as significant positive risk factors for intramyometrial lymphvascular space involvement (LVSI). On multivariate analysis, tumor grade, depth of MI, and mode of MI retained their significance. We created a grid for the relative risks of LVSI with respect to these variables individually or in combination. We suggest that our indirect estimate of the risk of LVSI can help in assessing prognosis and determining the need for adjuvant therapy whenever LVSI is important in clinical decision making, but its pathologic diagnosis is uncertain.     

Unusual course of an epidural rhabdomyosarcoma of the upper thoracic spine

Summary This report deals with a case of rhabdomyosarcoma in the upper thoracic spine. It is of particular interest, not only for the rarity of type and location of this tumour, but for its clinical course, which presented fluctuations of neurological status, included an acute demonstration of complete paraplegia followed by full recovery after conservative treatment, and gradual relapsing of neurological deficit, one year later.     

新时期戏剧艺术探索的成就与困顿

八十年代初中期 ,中国戏剧积极拓展我国传统戏剧的时空观、写意性特征 ,大胆借鉴西方现代戏剧的荒诞化、意象性技巧 ,出现了探索创新、多元发展的崭新局面。其中对“三一律、一堵墙”戏剧观的突破 ,运用意识形象外显人物的内心世界 ,嫁接多种艺术手段将现实时空转化为艺术时空 ,是新时期戏剧艺术探索最突出的三项成就。而过分强调形式技巧 ,脱离观众欣赏习惯 ,致使演出市场萎缩 ,观众锐减 ,无疑是新时期戏剧艺术探索中面临的最大困顿。

儿童颈椎间盘钙化的诊断和治疗

儿童颈椎间盘钙化症（cervical incervertebral dise calcification in children）是一种少见的疾病。1924年Baron首先报道本病．国内1982年至今陆续报道，迄今仅百余例。作者经治儿童颈椎间盘钙化症5例．结合文献对其诊断和治疗加以讨论。     

咽旁间隙原发性肿块流行病学分析

目的：对咽旁间隙原发性肿块进行流行病学分析。方法：对咽旁间隙原发性239例肿块进行统计分析。结果：原发良性肿瘤患病比为61．09％，其中上皮源性肿瘤患病比最高，占19.25％；神经源性肿瘤第二位，占17．57％。原发性恶性肿瘤的患病比为35．15％，其中上皮源性恶性肿瘤的患病比最高，占21.76％；恶性淋巴瘤第2位，占7．95％。炎症的患病比为3．77％，其中淋巴结反应性增生最高。结论：咽旁间隙原发性肿块良性肿瘤的患病比最高，恶性肿瘤次之，炎症居第3位，比例约为17：9：1。     

腰椎间盘突出症早期手术并发症的回顾性分析

腰椎间盘突出是腰腿痛的主要原因,因患病率高,手术开展较为普及,关于其手术后并发症的相关报导也逐渐增多。为了进一步了解这些并发症的发生原因,我们将1993年2月至2004年12月手术治疗腰椎间盘突出症768例中所发生的74例早期并发症进行回顾性分析,针对手术的危险因素提出相应的     

腰椎间盘突出症治疗方法与肌电图变化的相关性研究

腰椎间盘突出症(lumbar disc herniation，LDH)是导致腰腿痛的主要病因，本研究对具有典型临床症状、相应体征及MR或CT等影像学资料确诊的LDH，采用规范化非手术治疗，经规范化保守治疗无效者选用手术治疗，治疗前后均行肌电图(elec-tromyograptly，EMG)检查，旨在探讨肌电图变化与治     

Epidural blood patch illustrated by CT-epidurography

Four patients, who received epidural blood patch to treat postdural puncture headache, were examined with computed tomography in order to demonstrate the distribution of the injected blood. Blood alone could not be identified, but adding 2 ml contrast agent Iohexol 180 mg J/ ml (Omnipaque®, Nycomed Imaging) to 18 ml blood gave an excellent demonstration of the distribution of the blood in the epidural space, both cranio-caudally (7–14 segments) and spatially in relation to the epidural septae. The blood-contrast media had a strong affinity to the dural sac. There was no support of the spacefilling effect of blood patch.
