An unusual mechanical asphyxia in a homicide-suicide case by smothering and strangulation

A very unusual homicide of 2 children by smothering and strangulation by means of a rubber adhesive band carried out by the mother who committed suicide by the same manner is presented. Smothering is supposed to be one major cause of death in child homicide. Suicide by smothering is relatively uncommon. Suicidal smothering by winding strips of adhesive tape around the head to cover the nose and mouth is an even rarer method recently described in literature. The circumstances of the crime and the macroscopic and microscopic evidence are discussed to reduce the potential for underdiagnoses or mistakes in such cases in which it may be difficult to establish whether suicide or homicide occurred.     

PMCT在机械性窒息方面的研究进展

机械性窒息是公安法医日常检案中最常见的死因之一.如何快速准确的判断死者是否为机械性窒息死亡、以及作案手段是判断案件性质、指引案件侦破方向的重要因素.在法医鉴定过程中,诊断机械性窒息需要结合尸体体表征象、尸体内部征象、组织病理学检验等多方面综合判断.PMCT在骨折的检测、异物的检测和气体的检测方面具有极大的优势,在许多国...     

机械性窒息和CO中毒联合致死1例

在法医学实践中,死亡原因确定有时较为困难,尤其在多种原因并存时,更为困难。但死亡原因又是法医病理检验后必须回答的问题。笔者在最近的法医学实践中遇到1例机械性窒息和CO中毒联合致死案例,死亡原因分析较为困难,现报告如后。案例资料某女,40岁,农民。某日晨被邻居发现死在地上。同日进行法医病理解剖:尸斑呈淡红色,分别布于背侧,指压褪色。双侧睑结膜见多个针尖大小的点状出血。右口角附有血迹,右上唇内面一0.6cm×0.2cm浅裂创,左上、下唇见数个细小裂创伴出血,右上、下唇及口腔粘膜出血,上颌右第一切牙,左第一、二切牙缺失,缺失牙龈窝…

分子生物学指标用于推断机械性窒息死亡的研究进展

体表损伤轻微或无损伤的机械性窒息死亡是法医学鉴定的难点之一。由于缺少病理形态学特异性变化特征,较难与部分存在缺氧过程的其他致死原因相鉴别。近年来,将具有相关性、特异性分子生物学指标用于推断机械性窒息死亡,已成为研究热点。本文就上述专题中法医学最新研究文献进行复习综述,以期为机械性窒息死亡的研究提供新思路。     

An unusual case of compression asphyxia and smothering

Scene investigation is an important part of the medicolegal autopsy. In many cases the cause of death cannot be determined without knowledge of the circumstances. A case is presented in which the diagnosis of compression asphyxia and smothering was made only after analysis of the scene findings.     

mRNA和microRNA在机械性窒息死推断中的研究进展

机械性窒息死的推断是法医学鉴定的难点之一。利用实时荧光定量PCR（fluorogenic quantitative RT-PCR,RT-qPCR）技术检测RNA表达水平变化规律,并据之推测机械性窒息死亡的原因,近年来已成为研究热点。本文对mRNA和microRNA（miRNA或miR）在机械性窒息死推断的研究文献进行复习综述,并重点探讨miRNA在该类死因推断中的应用,以期为机械性窒息死推断提供新的思路。     

A case of autoerotic asphyxia associated with multiplex paraphilia

During the past 20 years, the sensational aspects of autoerotic fatalities have captured the attention of medical examiners, psychiatrists, law enforcement agents, and the public, as well as the individuals themselves who engage in these dangerous practices. Reports of deaths related to sexual asphyxia have been presented numerous times at national and international meetings and have been the topic of discussion on television talk shows and in the press. Autoerotic fatalities and all the sexual curiosities related to these activities have prompted death scene investigators to publish case reports, and even textbooks, on the subject. The case presented herein is one of a multicomponent paraphilia in which self-asphyxiation (autoasphyxiophilia) led to a fatal autoerotic event.     

An unusual fatal case of accidental asphyxia in a child.

The death of a three-year-old child by asphyctic mechanism is described. The child was accidentally suspended by the neck from a half-opened car window. This report details the form in which the accident occurred. The influence of the type of window and the autopsy findings.     

Detection of thyroglobulin in blood stains as an aid in the diagnosis of mechanical asphyxia

Mechanical forces applied to the neck region are known to release certain amounts of thyroglobulin into circulation. In this experiment, an attempt was made to detect thyroglobulin in bloodstains as an aid in the diagnosis of mechanical asphyxia. Experimental bloodstains containing thyroglobulin at concentrations of 1, 2, 5 and 10 mu g/mL were prepared on a sheet of filter paper. Small pieces of bloodstains, measuring approximately 2.4 cm2 in area, were extracted with 0.1 mL of distilled water and the extracts were tested against an antihuman thyroglobulin serum by precipitation-electrophoresis. Bloodstains containing more than 1 mu g/mL of thyroglobulin formed distinct precipitin lines for up to one month of storage, while bloodstains containing more than 5 mu g/mL of thyroglobulin formed distinct precipitin lines for up to three months of storage. The present results suggest that the bloodstains can be utilized in the diagnosis of mechanical asphyxia.     

Determination of a mechanism of the coming of death by morphological methods in strangulation mechanical asphyxia

Described in the paper are morphological data characterizing the tempo and type of thanatogenesis in strangulation asphyxia. The cerebral thanatogenesis was shown to prevail in mechanical asphyxia. The results of determination of a degree of hydration of the brain by drying its samples are described. Medullary substance was demonstrated to be hypohydrated in such death.

Enzyme-linked immunosorbent assay for determination of plasma thyroglobulin and its application to post-mortem diagnosis of mechanical asphyxia

A high sensitive enzyme-linked immunosorbent assay (ELISA) for determination of plasma thyroglobulin was devised and applied to the postmortem diagnosis of mechanical asphyxia. The sensitivity of the present ELISA was 5 ng/ml. All of the 15 victims who died from causes other than mechanical asphyxia showed plasma thyroglobulin levels lower than 200 ng/ml (99.8 +/- 37.9 ng/ml), while 12 out of 14 victims of mechanical asphyxia showed the levels higher than 200 ng/ml (2100 +/- 3450 ng/ml in 14 victims). Thus, the present ELISA appears to be useful for postmortem diagnosis of mechanical asphyxia.
