54例氯化琥珀胆碱中毒案件的法医学分析

目的观察分析氯化琥珀胆碱中毒案件的法医学表现,以期提高氯化琥珀胆碱中毒的检验鉴定。方法收集54例氯化琥珀胆碱中毒案例,通过病理学、毒理学变化及案件特点进行回顾性分析,观察氯化琥珀胆碱中毒的检验鉴定规律。结果氯化琥珀胆碱中毒的病理学表现以急性肺淤血、肺水肿等一般猝死改变为主,部分死者心肌排列紊乱及断裂。死者心血中均检见琥珀胆碱成分,皮肤组织部分检见琥珀胆碱成分。结论氯化琥珀胆碱中毒具有死亡快、手段隐蔽、难以抢救、易漏检等特点。对于猝死案件、死因可疑案件应将氯化琥珀胆碱作为常规检验指标,防止此类案件的未检或漏检。

胰岛素中毒法医学研究进展

胰岛素作为一种临床上常见的降血糖药物,可以有效控制糖尿病患者血糖,使之维持在正常范围。但过量胰岛素可导致死亡,其中以意外中毒最多见,其次为自杀,胰岛素他杀虽极为罕见,但值得高度重视。胰岛素中毒致死的法医学鉴定极为困难,虽然相关研究已取得一定的进展,但在法医学实践中,这类案件仍然是一大难题。本文从法医病理学的角度,对胰岛素中毒的死亡机制、病理学改变、检测手段、注意要点及诊断要点进行综述,为法医学实践提供帮助。     

Globus Pallidus Necrosis Unrelated to Carbon Monoxide Poisoning: Retrospective Analysis of 27 Cases of Basal Ganglia Necrosis

Bilateral globus pallidus necrosis is said to be characteristic of carbon monoxide (CO) poisoning. However, there has been no scientific test of this hypothesis. To examine the assertion that globus pallidus necrosis is typical of CO poisoning, this study examined autopsy cases from the King County Medical Examiner's Office (KCMEO) between 1994 and 2013. Twenty-seven cases with bilateral basal ganglia lesions were identified and examined for associated or causative disease or injury with the following results: 10 cases of drug overdose, seven heart disease, three asphyxia, two chronic ethanolism, two Huntington-like disorder, and one case each of remote trauma, rheumatic heart disease, and cerebral artery gas embolism. Additionally, review of all known cases at KCMEO of CO poisoning found no evidence of globus pallidus or basal ganglia necrosis. Thus, this study provides no support for the assertion that globus pallidus necrosis is characteristic of CO poisoning.     

Human Fatality Due to Thallium Poisoning: Autopsy,Microscopy, and Mass Spectrometry Assays,

Thallium has been responsible for many intoxications since its discovery; however, toxicological profiles for thallium in human fatalities have not been updated recently. Autopsy, microscopic investigations, and toxicological analyses were performed on a married couple who died from thallium sulfate intended homicidal poisoning. The distribution of thallium was established by inductively coupled plasma mass spectrometry with hair samples showing the highest thallium concentration. Electron microscopy revealed a dystrophic condition of hair with disorganized cuticle and atrophy of the hair bulb. Thallium interacts with cells at different levels, with prominent ultrastructural injuries in the mitochondria and endoplasmic reticulum, and high concentration of electron dense granules observed in the cytoplasm and mitochondria of several organs. Alopecia, toxic encephalopathy, and peripheral neuropathy were diagnosed in the victims and suggested to be crucial implications for thallium poisoning. The analytical procedures used in this case are of considerable forensic importance in the diagnosis of thallium poisoning.     

An Unusual Case of Strychnine Poisoning

Strychnine‐related death has been described since the 19th century. This alkaloid was discovered in 1818. Historically, strychnine was used by the South‐East Asian autochthones on their arrows. However, its production was modified by legislation, which was used to protect people against accidental intoxications. Here, we present the case of a 69‐year‐old man who was found dead at home. During the autopsy, we found a blue substance in the stomach. Toxicological analysis measured strychnine at 0.29 μg/mL in the blood sample, which is a relatively low level in comparison with the results given in the literature. However, histologic examination and toxicological findings permitted the conclusion of strychnine poisoning.

Intracoronary Thrombus Formation Following Carbon Monoxide Poisoning

Thromboembolic events in the context of carbon monoxide (CO) exposure have been well described in the literature. Six cases of clinically significant coronary thrombosis following CO exposure were previously reported. However, factors affecting the development of coronary thrombus in CO exposure are poorly understood, and the significance of this finding in a forensic context is not clear. This article discusses a case of coronary thrombosis found at autopsy following a death in which CO poisoning was suspected. A 67‐year‐old man was found dead in his garage with four vehicles with their ignition in the “on” position and their tanks empty. At autopsy, severe coronary atherosclerosis and an acute nonocclusive coronary thrombus were found. Given the dissimilarities among cases and the presence of CO exposure, it was suggested that the coronary artery thrombosis is likely due to the inherent prothrombotic mechanism of CO, the only common denominator in all the cases.     

Rare Death Via Histamine Poisoning Following Crab Consumption: A Case Report

Histamine poisoning (scombroid food poisoning) is a toxicity syndrome that results from eating spoiled fish. To date, however, few poisoning (or mortality) cases have been reported in relation to crab consumption. Here, we describe a very uncommon case in which a 37‐year‐old woman and her 14‐year‐old son ate cooked crabs (Scylla serrata), resulting in the death of the female. Samples of vomitus, food residue, liver tissue, gastric content, intestinal content, and cardiac blood were analyzed by high‐performance liquid chromatography. Toxicological analysis revealed that histamine concentrations were very high in the cooked crab (47.08 mg/100 g) and intestinal content (22.54 mg/100 g). Comparing our toxicological results, police investigations, and family member statements, it can be assumed that the decedent ingested spoiled crabs, and by excluding other causes of death, lethal intoxication with histamine poisoning was confirmed.     

Poisoning deaths in Central China (Hubei): A 10-year retrospective study of forensic autopsy cases

A retrospective study of autopsy cases was conducted at the Department of Forensic Medicine, Tongji Medical College (DFM-TMC), in Hubei, China to describe the characteristics of poisoning deaths from 1999 to 2008. A total of 212 poisoning deaths were investigated by DFM-TMC during the 10-year period. The poisoning deaths ranged from 17 cases in 1999 to 27 cases in 2008. Of the 212 cases, 82 deaths (38.7%) were from pesticides, 36 deaths (17.0%) from carbon monoxide, 34 deaths (16.0%) from drugs, 22 deaths (10.4%) from alcohol, 17 deaths (8.0%) from other chemicals, 15 deaths (7.1%) from poisonous plants and animals, and six deaths (2.8%) from heavy metals. Of the 82 pesticide poisoning deaths, 43 (52.4%) cases were caused by rodenticides, mainly tetramine (N = 39). The majority of poisoning deaths were accidents (63.7%), followed by suicides (25.9%) and homicides (3.8%). The manner of death could not be determined in 14 cases (6.6%).
