Clinical and Physical Evaluation of the Infertile Male: Testicular Measurement or Orchidometry/Klinische und physikalische Bewertung des infertilen Mannes: Hodenmessung oder Orchidometrie

Summary: For the quantitative determination of the testicular size or volume, two groups of apparatus are available: on the one hand, model testes, which are extremely valuable in longitudinal and cross-sectional studies during the period of pubescence, and on the other hand, measuring devices, with which the testicular dimensions can be specified. The latter instruments are helpful chiefly during the adolescent years and the diagnosis of problems surrounding fertility. The testicular volume can be calculated subsequently from the specific testicular measurements. The formula, for computing the volume of an ellipsoid, seems to be the most suitable for this purpose. Appliances also have been developed, which allow the largest (longitudinal) dimension (in mm) and the testicular volume (in cm3) to be read off simultaneously. A tonometer can be useful to quantitatively estimate the testicular consistency, which is a parameter of the testicular integrity at the level of tubular function (spermatozoa production).     

Zero-Order Release Formulation of Oxprenolol Hydrochloride with Swelling and Erosion Control

Zero-order release of oxprenolol hydrochloride was obtained by controlling the swelling and erosion of the matrix. This formulation involves only mixing of drug, hydroxypropylmethylcellulose (HPMC), and sodium carboxymethylcellulose (Na CMC) at the ratio of 1:0.4:1.6, respectively, and compressing the mixture directly into tablets. The in vitro release pattern from this optimized matrix tablet was reproducible. Accelerated stability studies revealed that the optimized formulation remains stable for an approximately 2-year shelf life. This sustained-release (SR) tablet was evaluated in dogs, and for comparison a conventional (CV) formulation was also given at the same dose level. Plasma oxprenolol levels were monitored by a sensitive and specific high-performance liquid chromatographic (HPLC) method. Significant differences in the pharmacokinetic parameters, i.e., lower C _max, higher values of t _max, MRT, AUC, and plasma concentration at 24 hr, and nearly constant plasma levels over 12 hr, indicated that the SR matrix tablet is superior to the CV rapid-releasing formulation. The in vitro release parameters and in vivo pharmacokinetics correlated well.     

病案质量问题与改进

病案作为记录医疗活动过程的重要载体,包含着各类丰富的信息。医疗服务质量评价有很多内容是通过病案实现的。作者分析了包括"三级医师查房"在内的20余项在病案中反映的医疗服务质量项目,指出影响质量判断的常见因素,并提出解决的对策与措施。     

用秩和比法对我院的10个公示病种医疗质量进行综合评价

目的对我院2005年度公示的10个病种进行医疗质量综合评价。方法采用秩和比法(RSR)进行统计分析。结果我院的10个公示病种被划分成4个医疗质量等级:老年性白内障、小儿支气管肺炎2个病种质量为优,急性阑尾炎、腹股沟疝(单侧)、子宫平滑肌瘤、剖宫产4个病种质量为良,胃大切、脑梗塞、急性心肌梗塞3个病种质量为中,脑出血1个病种质量为差。结论通过对综合指数秩和比(RSR)的计算并根据其值分级归档,反映出所研究病种之间存在着医疗质量高低的差异。控制和降低本院临床常见病种的医药费用,进行医疗全程连续性控制,为患者提供经济有效的医疗服务。     

肱骨髁间骨折的手术治疗及疗效评价

目的 探讨肱骨髁间骨折的手术方式并评价疗效。方法 1998年1月～2004年12月共手术治疗肱骨髁间骨折28例，进行随访分析。结果 28例中26例获随访，时间6个月～4年7个月，其中22例获2年以上随访。疗效评价参照casse‰。评分系统，优良率为65％。结论 骨折类型及手术方式直接影响预后。关节良好的复位和牢固的固定，以及术后早期积极的功能锻炼是得到良好疗效的保证。     

改良《颈性眩晕症状与功能评估量表》在椎动脉型颈椎病中医临床中的应用及评价

目的探讨改良《颈性眩晕症状与功能评估量表》在椎动脉型颈椎病(CSA)的中医临床中的应用可行性。方法151例CSA患者随机分为针灸推拿治疗组和单针灸对照组,治疗前后采用改良《颈性眩晕症状与功能评估量表》进行量化评估,并对该量表在本次中医临床中的效度及信度进行初步检验。结果治疗组治疗后症状与功能评分比治疗前有显著提高(p<0.01),治疗组改善指数明显高于对照组(p<0.05)。经检验,该量表也有可以接受的准则效度(r在0.8-0.9之间,p<0.01)和再测信度(r在0.6-0.9之间,p<0.01)。结论针灸推拿结合治疗CSA具有确切的临床疗效,能明显改善患者症状、颈椎功能和生活质量。改良《颈性眩晕症状与功能评估量表》在CSA中医临床中具有可信性、有效性。     

The ability of ‘family friendly’ organizational resources to predict work–family conflict and job and family satisfaction

The effectiveness of organizational interventions in reducing the adverse consequences of work–family conflict has produced mixed findings. This paper examines the relationship between the use of organizational ‘family friendly’ resources (such as crèche facilities, flexible working hours, and job sharing), with levels of work–family conflict, and job and family satisfaction over time. Using structural equation modelling, these associations were tested in 398 employed men and women who each completed a self‐report questionnaire administered on two occasions. The use of organizational interventions directly predicted increased levels of concurrent (Time 1) work–family interference and increased levels of subsequent (Time 2) job satisfaction. Both organizational interventions and family interventions (i.e. support) positively predicted subsequent family satisfaction. The research demonstrates that the provision of organizational ‘family‐friendly’ practices will produce improved psychological outcomes for employees. Copyright © 2005 John Wiley & Sons, Ltd.
