心肌致密化不全及其法医学鉴定

心肌致密化不全(noncompaction of ventricular myocardium,NVM)是一种罕见的特殊类型的心肌病.近年来对于NVM的临床报道和研究越来越多,已成为临床心血管方面研究的热点问题之一.虽然NVM较为罕见,但因其猝死发生较多,加上目前我国大多数法医工作者对此认识不足,同时,现阶段还没有非常成熟的法医病理学检查方法,且其易与其他类型心脏疾病相混淆,因此对NVM的法医病理学鉴定需要充分的认识和格外谨慎.现重点对NVM的病理学特点、常用的临床诊断方法及与其他类型心脏疾病的鉴别诊断进行综述,并总结其法医学鉴定要点.     

试论法医病理学检验标准体系

现有的法医病理学技术鉴定标准在提高办案质量,促进鉴定工作标准化过程中发挥了重要作用。随着法医病理学研究手段及鉴定内容的发展,须加快标准建立的步伐并对现有标准进行补充或修正,并加强标准的宣贯力度。尽早建立和完善符合我国国情的法医病理学检验标准体系。

外伤性癫痫的法医学鉴定21例分析

为了探讨颅脑损伤后癫痫的法医学鉴定要点,对 21例颅脑损伤后癫痫出现发作者进行了现病史、既往史调查,并结合临床脑电图（ EEG）及 X线片、 CT片、 MRI片等影像学资料。结果发现外伤后癫痫常继发于严重的颅脑损伤,多以晚期发作为主,其发作性质决定于颅脑损伤的部位和程度,头皮 EEG和 24小时动态 EEG证实有异常癫痫样波存在,影像学检查有助于定性分析。结果提示：外伤性癫痫法医学鉴定必须以掌握外伤史及既往史为基础,结合 EEG、 CT、 MRI等检查方可作出正确鉴定。     

早期心肌梗死死后诊断的法医病理学研究进展

心源性猝死在成人猝死的死因中占首位,心肌梗死是冠心病猝死的主要机制之一,由于早期心肌梗死发生突然,且可在短时间内死亡,肉眼和镜下都缺乏典型的形态学改变,一直都是法医实践中研究的热点,本文回顾多年来心肌梗死的研究成果在法医学中的应用及局限,展望新的临床指标在法医工作中的可行性,期望提高死后心肌梗死诊断的准确率。     

KCNE、KCNQ1与心性猝死的相关性研究进展

部分心性猝死由于缺乏明确的病理学改变,其鉴定工作一直是法医工作者的一大难题。近年来,与长QT综合征、心房颤动等致死性心律失常疾病相关基因（KCNE基因家族与KCNQl）等研究逐渐增多。国内外研究发现KCNE和KCNQ1基因编码心肌钾离子通道,其基因异常可引起严重的心律失常,甚至导致心性猝死。因此,死后KCNE和KCNQl的基因检测对于心性猝死鉴定具有重要意义。本文对KCNE、KCNQl与心性猝死的相关性研究进展进行综述,希望能为法医学研究和实践提供参考。     

Sudden epilepsy deaths and the forensic pathologist

Sudden unexpected deaths in epileptic persons are not rare events, most commonly encountered by the forensic pathologist rather than the clinician. Such deaths may represent 1-1.5% of all "natural" deaths certified by the medical examiner or coroner. The typical victim is a black male about 30 years of age who tends to abuse alcohol, with a history of generalized epilepsy for more than 1 year and likely for more than 10 years. There are a lack of obvious anatomic causes for the death at autopsy, but 60-70% of cases will have a lesion in the brain (most commonly old trauma) to explain the epilepsy. Most victims have no blood levels of anticonvulsant medications at the time of death. We have evolved a form for use by medical examiner/coroner's investigators at the scene to collect relevant information which will be of assistance to the pathologist in interpreting the case. Estimated prevalence of sudden epilepsy death, mechanisms, and other features of such cases are reviewed briefly.     

IMA和H-FABP在心源性猝死法医学诊断中的应用

急性心肌缺血的发生是心源性猝死的最常见原因,而如何认定早期急性心肌缺血是法医学研究的热点,同时也是临床预防心肌梗死发生的重要环节。本文通过对缺血修饰白蛋白(ischemia modified albumin,IMA)和心型脂肪酸结合蛋白(heart-type fatty acid binding protein,H-FABP)的结构、功能、临床应用价值及法医学中的应用前景进行综述,旨在分析二者是否可作为早期心肌缺血的生化检测指标用于心源性猝死的诊断,并为今后选择心源性猝死的科研方向提供借鉴。     

Sudden death due to undiagnosed Wilms' tumor in an adult

Sudden unexpected deaths due to natural causes constitute a large number of cases encountered by the forensic pathologist. In a majority of such cases, heart disease is responsible for sudden death. Rare disease entities resulting in sudden death are occasionally encountered and may not fit the classic epidemiological profile. We present a case of sudden death due to a previously undiagnosed Wilms' tumor (WT) in an adult. The pathology of WT is discussed, as is the topic of sudden death due to previously unrecognized malignancy.     

Unexpected perinatal death and sudden infant death syndrome (SIDS): anatomopathologic and legal aspects

This work intends to be a review of the recent histopathological findings elicited by research into sudden and unexpected perinatal death and sudden infant death syndrome (SIDS) that have dictated a novel approach to the inherent problems by pathologists, especially those entrusted with forensic medical authority. The new approach stems from the recent advances made in the understanding of neuro- and/or cardiac-conduction-system diseases present in unexpected perinatal death and SIDS. These demand that an accurate morphologic examination be performed of these structures, which modulate respiratory, cardiovascular, digestive, and arousal activities, in all victims of sudden death. A histopathologic study of an ample register of cases of victims of sudden death, either perinatally or in early infancy, has demonstrated frequent alterations both of the autonomic nervous system (especially hypoplasia of the arcuate nucleus) and of the cardiac conduction system (accessory atrioventricular pathways). The present research provides an in-depth study of the many still-controversial aspects underlying perinatal unexpected death and SIDS and is recommended for professionals working in the forensic field, whose greater insight into this problem will allow more complete medicolegal documentation.     

Sudden death caused by parasites: postmortem cerebral malaria discoveries in the african endemic zone

This survey presents several cases of sudden deaths in Africa, specifically in Cote d'Ivoire, where the postmortem diagnosis of human cerebral malaria was determined after autopsy followed by pathologic examination of the brain. It is thought that cerebral malaria may be the primary cause of sudden death in nonimmunized persons during or after traveling in such endemic areas of Africa. The target population is composed of tourists, business travelers, and sailors. Because death caused by cerebral malaria occurs so suddenly, it can lead to forensic issues. Therefore, in any cases involving sudden death, it is very important for the forensic scientist to do a systematic evaluation, including pathologic examination of brain tissue, to rule in or exclude cerebral malaria. This practice will reinforce and aid research in progress directed at developing a vaccine and elucidating the role of tumor necrosis factor in this disease. Furthermore, this study will alert the physician to the importance of an effective and well-followed prophylaxis.
