Postmenopausal Women With Colles'' Fracture Have Lower Values of Bone Mineral Density Than Controls as Measured by Quantitative Ultrasound and Densitometry

Measurement of ultrasonographic parameters provides information concerning not only bone density but also bone architecture. We investigated the usefulness of ultrasonographic parameters and bone mineral density (BMD) to evaluate the probability of Colles' fracture. Two-hundred eighty-nine postmenopausal women (62.3 +/- 8.7 yr) with (n = 76) and without (n = 213) Colles' fracture were studied. BMD of lumbar spine and proximal femur was evaluated in all women by dual-energy X-ray absorptiometry (DXA) and speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness in the calcaneus were measured by a Sahara ultrasonometer (Hologic). Patients suffering from Colles' fracture had lower values of BMD adjusted by height at the lumbar spine, L2-L4 (0.797 g/cm2 vs 0.860 g/cm2), femoral neck (0.685 g/cm2 vs 0.712 g/cm2 ), SOS (1518 m/sg vs 1525 m/sg), and stiffness (74.6 vs 77.7) (p < 0.05). Nevertheless, BUA values were similar in both groups. After stepwise logistic regression analysis, the area found under receiver operating characteristic (ROC) curves was 0.60 for L2L4 and 0.63 for a formula combining L2L4 and height. Our data suggest that patients suffering from Colles' fracture have lower values of BMD by DXA, SOS, and stiffness. However, the ability of these techniques to discriminate is low because the values for the area under ROC curve are 0.60 for L2-L4 and 0.63 for a formula derived of the combination of L2-L4 and height.     

间接免疫荧光法检测婴幼儿急性下呼吸道合胞病毒感染的特异性IgM

本文对1984年1～3月和1985年3～8月共107例急性下呼吸道感染的住院患儿,采用间接免疫荧光法检测其急性期血清抗RSV特异性IgM抗体,并与病毒分离和/或中和试验比较,敏感性为82.1％,特异性为71.8％。RSV感染患儿发病后3天内大多数病例即可从血清中检测出RSV-IgM,因此该法具有早期诊断价值。     

“肠梗”治疗粘连性肠梗阻425例

本文对采用自行研制的中草药浓缩剂“肠梗”治疗的粘连性肠梗阻４２５例进行临床分析。根据不同的病理及临床特征将其分为三种类型，其中广泛粘连型是“肠梗”治疗的最佳适应症，粘连扭转型是其禁忌证。并对中转手术的指征、时间等问题进行了讨论。认为该方法具有简单易行、安全可靠、成功率高的特点，是一种易于推广的治疗粘连性肠梗阻的有效方法，具有较高的临床实际应用价值     

胫骨延长术后的功能康复程序初探

胫骨延长术是矫治小儿麻痹后遗症下肢短缩最常见的术式，但如何恢复或改善术后的功能，目前尚无一套系统的程序。本文作者根据自行设计的胫骨延长休后功能康复的临床观察，作较系统地介绍，并就该程序的合理性，进行了讨论与论证。

50岁以上肾移植的临床分析

自１９８９年１月～１９９５年１２月共施行同种异体尸肾移植术５５６例次，其中５０岁以上患者１８２例（３２７％），对这些患者的临床资料进行比较分析。结果显示：５０岁以上组１、３、５年的人／肾存活率分别为８３４％／７９３％、７７１％／７１１％和５４５％／４５５％，与４９岁以下组比较差异无显著性（Ｐ＞００５），急性排斥发生率并不比４９岁以下组高，并发症发生率尤其是感染发生率及致死率均高于４９岁以下组（Ｐ＜００５）。本资料说明，年龄不是肾移植的主要影响因素，感染和心血管并发症是主要的死亡原因和影响长期存活的因素。适应证的选择和术前充分透析，术后合理应用免疫抑制剂，定期复查及心、肝、肺功能的监护，是提高高龄肾移植患者长期存活的主要因素。
