Reduction of postmortem angiography-induced tissue edema by using polyethylene glycol as a contrast agent dissolver

Postmortem investigation is increasingly supported by computed tomography (CT) and magnetic resonance imaging, in which postmortem minimal invasive angiography has become important. The newly introduced approach using an aqueous contrast agent solution provided excellent vessel visualization but was suspected to possibly cause tissue edema artifacts in histological investigations. The aim of this study was to investigate on a porcine heart model whether it is possible to influence the contrast agent distribution within the soft tissue by changing its viscosity by dissolving the contrast agent in polyethylene glycol (PEG) as a matrix medium. High-resolution CT scans after injection showed that viscosities above c. 15 mPa s (65% PEG) prevented a contrast agent distribution within the capillary bed of the left ventricular myocardium. Thereby, the precondition of edema artifacts could be reduced. Its minimal invasive application on human corpses needs to be further adapted as the flow resistance is expected to differ between different tissues.     

几种视觉诱发电位技术推断正常成人远视力的比较

目的比较研究几种图形视觉诱发电位技术对视力推断的价值。方法取正常眼40只,分别测试其图形翻转视觉诱发电位、黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位,据此推算实验视力,分别与真实视力进行比较,同时各种方法进行彼此比较。结果黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位较之图形翻转视觉诱发电位能更为准确、方便、快捷地反映真实视力水平。结论黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位与图形翻转视觉诱发电位一样,可用于眼外伤的法医学鉴定。     

心外科手术后死亡医疗纠纷尸检分析

目的从尸检角度讨论心外科手术后死亡的死因及诊疗缺陷。方法按临床诊断、手术类型、死亡时间、死亡特点、尸检特点、纠纷特点、诊疗缺陷等方面,比较所选案例的临床、尸检资料特点。结果心瓣膜置换手术4例,冠心病冠脉搭桥手术1例,先心病大动脉转位手术1例。心肌梗死2例,心肌广泛损伤1例。心内膜感染2例,多器官功能衰竭1例。家属怀疑诊疗不当6例。诊疗缺陷主要为手术适应证、手术时机,手术器材的选用,手术操作,术后病情观察、处理不及时,对病情严重程度、手术风险及预后的告知不充分。结论尸检不仅能查明死因,还可帮助评价手术质量、术后处理的诊疗质量,对解决纠纷具有重要的辅助作用。

我国医疗旅游现状与对策

世界旅游组织预测,到2015年我国将成为世界第一大旅游目的地国和第四大客源输出国。医疗旅游作为新的旅游资源已经引起很多国家的重视。我国的医疗旅游应借鉴周边国家的经验,结合我国的实际情况,从多方面着手,逐步发展。     

The association between body mass index and pulmonary thromboembolism in an autopsy population

Abstract: To evaluate the association between obesity and pulmonary thromboembolism (PTE) in a forensic context, 160 autopsy cases of fatal PTE were compared with age‐ and gender‐matched controls. The mean age of cases was 66 years (range 26–98 years; M/F 74:86). The mean body mass index (BMI) of cases with PTE was 30.88 (range 14.95–79.51), which was significantly higher than in the controls (mean BMI = 25.33; range 12.49–61.84) (p < 0.0001). Comparing the group with PTE with controls showed that five (3.1%) compared to 20 (12.5%) were underweight, 39 (24.4%) compared to 67 (41.88%) were of normal weight, 49 (30.63%) compared to 43 (26.88%) were overweight, 43 (26.88%) compared to 24 (15%) were obese, and 24 (15.0%) compared to six (3.75%) were morbidly obese. In each category of above‐normal BMIs, there were significantly greater numbers in the groups with PTE: overweight (p < 0.01), obese (p < 0.001), and morbidly obese (p < 0.0001).     

论过度医疗侵权行为及其法律规制

过度医疗一般是指,在医疗过程中,医师对患者的疾病实施不必要的诊疗措施,致使患者的医疗费用明显超过疾病诊疗实际需求的医疗行为或医疗过程。过度医疗认定的关键,在于把握过度医疗行为与适度医疗行为的界限,并且应将其与保护性医疗和防御性医疗加以严格区分。从法律意义上讲,过度医疗是一种发生在医疗过程中的特殊民事侵权行为,是指医疗机构及其医务人员在医疗活动中,以获取一定经济利益为目的,违法实施不必要的诊疗从而造成患者明显人身、财产损害并应承担相应法律责任的行为。过度医疗侵权应适用过错推定责任进行归责。《侵权责任法》立法上将过度医疗的范围,仅局限在"实施不必要的检查",不足以充分保护患者的合法权益,立法上应进一步做出扩充解释。     

精神鉴定的评价范围——基于鉴定人与司法人员职权划分的思考

精神鉴定的评价范围涉及鉴定人与司法官的职权划分问题。在我国,精神鉴定的评价范围不仅包括医学要件与心理学要件,也包括刑事责任能力的内容,精神鉴定人通常都直接对刑事责任能力作出评定,此做法既与理论上的观点不一致,也与刑事诉讼法的规定不相吻合。较为合理的做法是由精神鉴定人对刑事责任能力的医学要件进行评定,心理学要件的判断则采用以司法人员为主、鉴定人为辅的合作方式。
