Two unusual cases of suicide by hanging

Two unusual cases of suicide by hanging are described, in the first case the deceased's left hand tied to the left thigh with the head and face covered by a heavy winter coat. In the second case the deceased's hands were tied behind his back.     

自杀的心理解剖

自杀是重要的公共卫生问题。但目前国内的研究焦点主要关注的是怎样预测和预防自杀的发生等方面,对自杀者的心理解剖工作却几乎没有开展。本文重点介绍并讨论了已经在国外开展了40年的针对自杀者的心理解剖工作的概念、工作原则和具体操作方法,为国内专业人士更准确地了解自杀者死亡的心理学原因和其他相关的危险因素,为更好地预防和控制自杀提供了一条新的途径。     

Fatal intoxication with tianeptine (Stablon)

Tianeptine (Stablon^®), although structurally similar to tricyclic antidepressants, acts by enhancing the reuptake of serotonin. A fatal case is presented involving a 26-year-old man, found lying in bed with a “mushroom of foam” around his mouth. Empty blister packs of Stablon^® and a suicide note were found next to the body. A liquid–liquid extraction procedure with n-hexane: ethyl acetate and n-hexane: 2-propanol, followed by LC-DAD-MS analysis, using positive mode electrospray ionization was performed. The detection limit was 0.001 μg/mL. The toxicological results revealed the following tianeptine concentrations in the post-mortem samples: blood 5.1 μg/mL; urine 2.0 μg/mL; liver 23 μg/g; stomach contents 22 mg. Femoral blood analyses also revealed an ethanol concentration of 0.53 g/L. The present method was also developed and validated for the other post-mortem specimens, since no previous published data had confirmed the post-mortem distribution of tianeptine. The absence of other suitable direct causes of death (macroscopic or histological) and the positive results achieved with the toxicological analysis led the pathologist to rule that death was due to an intoxication caused by the suicidal ingestion of tianeptine in combination with alcohol.     

Suicide due to oral ingestion of lidocaine: a case report and review of the literature

The Authors describe a rare case of suicide in a 31-year-old woman, due to oral ingestion of lidocaine; the histological and toxicological findings are discussed to provide useful information to the present experience with this particular modality of death. Histological examination revealed generalized stasis. In the myocardium we observed segmentation of the myocardial cells and/or widening of intercalated discs and associated group of hypercontracted myocardial cells with "square" nuclei in line with hyperdistended ones. Non-eosinophilic bands of hypercontracted sarcomeres alternating with stretched, often apparently separated sarcomeres, small foci of paradiscal contraction band necrosis, and perivascular fibrosis were observed too. Lidocaine was detected in the subject's urine through immunoenzymatic screening. Toxicological analysis by solid-liquid extraction and gas chromatography-mass spectrometry (GC-MS) analysis, was carried out to identify and quantify the individual substances present in the biological fluids and organs. Lidocaine concentrations were as follows: blood 31 microg/mL, gastric content 2.5 g, liver 10 microg/g, kidney 12 microg/g, brain 9 microg/g, spleen 24 microg/g, lung 84 microg/g, heart 9 microg/g, urine 9 microg/mL, and bile 6 microg/mL. No other drugs or alcohol were detected. When blood lidocaine reaches toxic levels, serious toxic symptoms associated with the central nervous system and cardiac system are noted. The overdose of lidocaine produces death from ventricular fibrillation or cardiac arrest. In this case, according to macroscopic and microscopic findings, the cause of death was most likely cardiac and possibly related to ventricular fibrillation.     

Filicide: A Comparison by Sex and Presence or Absence of Self-destructive Behavior

The purpose of this study was to identify sociodemographic, contextual, situational, and individual variables, as well as certain behavioral warning signs, associated with filicide as a function of sex of the agressors and the presence or absence of self-destructive behaviours. The data cover all officially registered filicides committed in Quebec from January 1, 1986, to March 31, 1994, against youths under the age of 18 years. For the group of individuals who have self-destructive behaviours, results indicate that men compared to women are more likely to commit spousal homicide, to kill a higher number of victims, to be going through a conjugal separation, to have committed conjugal violence, to have threatened suicide, and to have threatened to kill their spouse. For the group of individuals who commit no self-destructive acts, women are more likely to present with a depressive disorder, whereas men are more likely to maltreated their children. Men who do not commit a self-destructive act are characterized by a significantly higher likelihood of maltreatment against their children and of tyrannical discipline, whereas men who commit a self-destructive act perpetrate filicide as a means of reprisal against their spouse. Results underscore the importance of considering the different groups of individuals who commit filicide as a function of sex as well as presence or absence of self-destructive behaviour.

我国农村妇女自杀问题初探

农村妇女自杀问题已成为我国当前一个日益凸显的社会问题。家庭暴力、传统文化的落后思想、经济能力不足等是导致农村妇女自杀率高的主要原因。为解决农村妇女自杀问题,必须采取加大教育普及力、提高执法力和加强对农村妇女的心理援助等重要防治举措。     

Suicidal yew ingestion

A 41-year-old man was found dead, lying in prone position on the ground near a parking area, where the car of the person was parked. Remarkable were the spasm-like hands of the decedent, cause of death was unknown. Primary an epileptical attack was assumed. A medicolegal autopsy was performed followed by histological and forensic toxicological analysis. Furthermore a plant anatomical investigation was applied. Autopsy revealed fragments of greenish needle-like leaves in the stomach and the intestines, but not in the colon. Plant anatomical investigation indicated the presence of yew. Histological findings were in concordance with the literature, in addition the investigation of bone marrow was performed for the first time. Forensic toxicological analysis revealed the presence of 3,5-dimethoxyphenol, the marker for intoxication with taxus baccata.This case reports the importance of medicolegal examinations in order to avoid misdiagnosis. Here the suspection of an epileptical attack as a possible cause of death was excluded by an autopsy, in addition an intoxication by yew leaves was proved.     

Homicide and suicide by aircraft

A report of simultaneous homicide and suicide by aircraft is presented. This confirms the view of Phillips (Science, 201 (1978) 748–750), that despite the previous absence of similar reports in the history of civil aviation, such incidents may occur, and that therefore murder and suicide should be considered as a possible cause of aircraft accidents.     

三类高坠案件的特点和现场勘查要点

高坠案件可分为自杀高坠案件、他杀高坠案件和意外高坠事件。高坠现场勘查是现场勘查的难点，在现场勘查中要及时周密地开展现场调查访问工作；认真详细地对尸体坠落点、尸体位置及周围环境开展勘查；加强对室内环境、门窗及房间钥匙开展勘查与检验；重点严密地对坠落地点周围的环境开展勘查；科学严谨地对“坠落通道”开展勘查。
