The Relative Contribution of Domains of Quality of Life to Overall Quality of Life for Different Chronic Diseases

This study examined the contribution of the quality of life (QoL) domains physical, social and psychological functioning to the explanation of overall QoL. Various disorders may differentially affect QoL domains due to disease-specific factors and, consequently, the relationship between QoL domains and overall QoL may vary between diseases. We therefore studied this relationship for several diseases as well as the differential impact of these diseases on QoL. The present study had a cross-sectional design. We selected patients (aged 57 years and older) with one of the following eight chronic medical conditions: lung disorder, heart condition, hypertension, diabetes mellitus, back problems, rheumatoid arthritis, migraine, or dermatological disorders. The total group of respondents included 1457 patients and 1851 healthy subjects. Regression analyses showed that the domain of psychological functioning contributed to overall QoL for all disorders, whereas physical and social functioning contributed to overall QoL for some disorders. Differences were found between most patient groups and healthy subjects with respect to physical functioning; with respect to social and psychological functioning some groups differed from the healthy group. Explanations for the findings and implications for clinical practice are discussed.     

Modified Kalish osteotomy: A simple approach to minimizing proximal dorsal stress risers

Proximal dorsal stress risers are a potential complication to the Kalish osteotomy. The authors describe a modification to this osteotomy that is simple and effective. Since performing the wing-clip modification, there have been no observed stress risers.     

无张力阴道吊带术治疗女性压力性尿失禁(附20例报告)

目的 评价无张力阴道吊带术(tension-free vaginal tape，TVT)治疗女性压力性尿失禁的疗效。方法 总结采用TVT术治疗女性压力性尿失禁20例的临床资料。结果 平均手术时间26.5min。拔除尿管后，19例病人控尿满意，1例仍有轻微尿失禁。术后平均随访12(3-24)个月，20例病人均无尿失禁。合并症有1例膀胱穿孔，1例术后轻度排尿不畅，2例尿频尿急。结论 TVT术操作简便快捷，创伤小，合并症少，术后康复快，是一种治疗女性压力性尿失禁的理想方法。     

Anaesthesia monitoring: the human factors component of technology transfer

Resistance to change in monitoring practices from within the anaesthesiology community is a formidable obstacle, and coercive and exhortatory solutions are likely to be unsuccessful in some situations. An analysis of publications about technology transfer and professional obsolescence, and application of this data to the practice of anaesthesia, reveals various stresses that technology transfer from research areas to the workplace may induce in vulnerable anaesthesiologists and account for their attitudes. It is suggested that the invaluable pronouncements of high profile anaesthesiologist groups must be supplemented by supportive behaviour by physicians and administrators at an institutional level. The human factors issues to be addressed include: (i) Monitored data acquisition skills. (ii) Possibility of acting on monitored data. (iii) Assistance for personal insight into attitudinal difficulties that may be encountered. (iv) Data supporting the value of the device. (v) Ergonomically effective integration of the monitor into the work station.Alternatively the perceptions of potential users may accurately reflect changes in their status in the new work situation created by monitors, and decision making aids that may or may not be derived from them. Thus, plans to present job satisfaction in related clinical areas or to associate the proposed new system with evaluation of its effect on patient outcome will be necessary. In this way the clinician becomes involved in clinical research, a quality of personal and quality care development.     

急性应激性溃疡模型的实验研究

本实验观察不同时间与方法所造成的应激性溃疡的模型。结果:禁食48小时,捆绑加浸水5小时,松绑后19小时,实验鼠胃粘膜出现多数病灶深、范围大、分布广的病灶,表现为出血、糜烂和溃疡,可谓最佳模型。     

中长跑和芭蕾舞运动中胫骨应力骨折的比较

胫骨应力骨折（ＳＦ）在芭蕾舞和中长跑运动员中均有一定发病率，作者调查某部新兵２６５人每日５０００米跑步，其胫骨应力骨折病发率为１１．６８％（３１／２６５人），骨折部位多在胫骨中段中后侧。芭蕾舞演员胫骨应力骨折病发率为８％（１５／６０人），骨折部位在胫骨下段前侧。应用新鲜尸体标本作负荷下胫骨多处的应变测定模拟跑步和足跟垫高模仿芭蕾舞时下肢负重位置的应变变化，分别于胫骨中段后侧测得有高压应力和胫骨下段前方有高张应力，此结果与调查中Ｘ线片病变部位相符。作者认为不同的运动使负重时胫骨所处姿势各不相同，而造成胫骨最大应力集中点位置各异，是造成芭蕾舞运动和中长跑运动中应力骨折部位不同的主要原因，预防和治疗工作应根据各自的应力性质和集中点部位来进行防治。     

Boundary Ambiguity in Parents With Chronically Ill Children: Integrating Theory and Research

Abstract: This article integrates theory and research related to boundary ambiguity in parents of children with a chronic health condition. We propose that boundary ambiguity is a risk factor for psychological distress in these parents. Clinical applications and a case example highlight how boundary ambiguity can be assessed and managed in clinical settings by professionals working with parents with chronically ill children. Questions are provided for assessing boundary ambiguity in clinical and research settings, and implications for research are discussed.
