创伤性睾丸脱位5例报告

目的 探讨创伤性睾丸脱位的诊断和治疗。方法 对所收治的5例患的诊治情况进行分析研究，并结合复习有关献。结果 1例手法复位成功，4例行手术复位．1例发生睾丸萎缩后切除患睾。结论 创伤性睾丸脱位临床少见，漏误诊率较高。对骨盆部、会阴部、阴囊部外伤患应警惕本病；详细检查阴囊及睾丸．确诊后尽早行手法或手术复位固定．定期随访。     

急性重度眼烧伤135例临床分析

目的了解急性重度眼烧伤的临床特点、预后及并发症发生情况。方法对笔者单位病案室保存的1977--2002年住院眼烧伤患者135例（155只眼）的病历进行回顾性统计分析。分析不同深度、原因眼烧伤的眼表修复率、修复时间、致盲情况及并发症。结果治疗后Ⅲ度眼烧伤的修复时间短于Ⅳ度眼烧伤，其修复率也明显高于Ⅳ度眼烧伤（P〈0．01）；在不能修复的Ⅳ度眼烧伤中，酸烧伤致角膜穿孔6只眼，显著高于碱烧伤（1只眼，P〈0．05）。Ⅲ度眼烧伤视力≥0．05者有38只眼，〈0．05者51只眼；Ⅳ度眼烧伤视力≥0．05者0只眼，〈0．05着66只眼。78只酸、碱烧伤眼中，52只眼致盲，致盲率为66．7％；77只热烧伤眼中，65只眼致盲，致盲率为84．4％。Ⅲ度眼烧伤的并发症发生率低于Ⅳ度眼烧伤。其中Ⅲ度眼烧伤角膜穿孔、睑球粘连的发生率（1．1％、36．O％）均显著低于Ⅳ度眼烧伤（27．3％、59．1％，P〈0．01）。在酸烧伤患者中，角膜穿孔及睑外翻的发生率（29．2％、37．5％）较高。而热烧伤患者中眼睑球粘连的发生率（53．2％）较高。结论Ⅳ度眼烧伤伤后的预后差，致盲率高。目前的治疗方法尚不能完全改善其视功能及预后，有待进一步研究。     

等密度硬膜下血肿的CT诊断(附47例分析)

本文分析了47例等密度硬膜下血肿的CT表现,观测的各种CT征象,发现(1)bolus增强扫描显示的血肿、血肿膜及表面移位血管;(2)中线结构的特征性偏移;(3)表面脑回聚拢内移;(4)脑灰白质界面内移;(5)侧脑室变形和脑—脑室指数变小,对等密度硬膜下血肿的诊断和鉴别诊断有重要意义。     

The biomechanics of vibration and low back pain

This work is a review of the mechanical factors related to low back pain production in a vibration environment. The sitting posture is an extreme orientation for the lumbar intervertebral disc that 1) increases its internal pressure, 2) increases its anteroposterior shear flexibility, while: 3) decreasing its resistance to buckling instability and 4) stressing the posterior region of the disc. Vibration is an additional mechanical stressor. Several studies suggest that the following preventive measures be taken to reduce the risk of low back pain due to driving: 1) minimize the vibration reaching the driver, 2) avoid lifting or bending immediately following driving, and 3) walk around for a few minutes following driving. © 1993 Wiley-Liss, Inc.     

Hepatobiliary scintigraphy in a patient with bilhemia

A 4-year-old child referred for acute jaundice following percutaneous needle biopsy of the liver underwent hepatobiliary scintigraphy. Although all conventional liver tests suggested preservation of hepatocyte function, the tracer uptake in the liver appeared dramatically reduced at scintigraphy and the blood pool activity did not decrease significantly until the end of the study. Visualization of the bile ducts indicated, however, that the tracer was taken up by the hepatocyte and further excreted into the biliary tree. There was no tracer pooling in the biliary tree although no bowel activity was observed, even on delayed images. The association of persistent blood pool activity, bile duct visualization without tracer pooling, and nonvisualization of the bowel was caused by a continuous recirculation of the tracer from the biliary tree into the bloodstream. The presence of a biliovenous fistula was further proven by percutaneous transhepatic cholangiography performed 24 h later. Since 1975, only 16 cases of bilhemia have been reported. To the best of our knowledge the scintigraphic pattern of this rare but lifethreatening complication has not previously been reported.     

腰穿放液治疗160例外伤性蛛网膜下腔出血的体会

目的：探讨腰穿放液对外伤性蛛网膜下腔出血的作用。方法：对１６０名外伤性蛛网膜下腔出血的病人行腰穿放液，少则２次，多则７次。结果：所有病人症状均好转，从脑脊液的力学上看脑脊液恢复正常性状的时间缩短，结论：腰穿放液治疗外伤性蛛网膜下腔出血是十分有效的方法，近期内临床症状明显改善，远期并发症减少。     

IL－2LAK细胞局部治疗眼部恶性肿瘤的临床效果

应用γＩＬ－２体外诱导自身ＬＡＫ细胞（ｌｙｍｐｈｏｋｉｎｅａｃｔｉｖａｔｅｄｋｉｌｌｉｎｇｃｅｌｌ），对眼部早、中期恶性肿瘤病人进行瘤区注射，取得较好效果。２５例恶性肿瘤中，ＩＬ－２ＬＡＫ细胞治疗１０例；肿瘤完全消退９例，部分消退１例。手术＋ＩＬ－２ＬＡＫ细胞治疗１５例，肿瘤完全消退。随访中除１例肿瘤部分消退失访外，其他２４例经１～５年观察均未见复发。以上结果表明，自身ＬＡＫ细胞局部治疗是一种有效的肿瘤免疫治疗方法。     

37例创伤死亡病例分析

本文对住院因外伤致死者进行了一般分析，说明创伤造成死亡占总死亡人数之６３。７％，而其中６５％均为青壮年和中年，并着重对颅脑损伤的死亡情况加以分析，提出对特重型颅脑外伤当非手术疗法无效时，应行手术探查减压，另外对腹部挫伤和烧伤及开放性骨折引起死亡的病例进行了讨论。
