人身侵权债权在破产清偿顺位中优先受偿之思辩

在调整人身侵权债权的各种制度中,为人身侵权债权在破产清偿顺位中找寻优先清偿点是次优制度选择,因为无论人身侵权债权定位在哪一个清偿层面都是后序债权人为破产企业的非法行为买单。为此,在其他法律制度足以保护人身侵权债权人权益的前提下,在破产清偿顺位中为人身侵权债权人设置优先受偿权实属不必要。但是其他法律制度不足以保护人身侵权债权人的权益时,我们可以考虑在破产清偿顺位中采用将人身侵权债权与劳动者债权同序的方式来保护人身侵权债权人的合法权益。

An Evaluation of Childhood Deaths in Turkey Due to Yellow Phosphorus in Firecrackers

Yellow phosphorus (YP) is a powerful protoplasmic poison used in the manufacturing of matches, pest poisons, firecrackers, firework cracker, lights for watches, military ammunition, and agriculture fertilizer. YP is extremely flammable and toxic and easily absorbed from the gastrointestinal tract. In this study, we examined childhood deaths from 1997 to 2012 resulting from the ingestion of firecrackers. The patients ranged from 2 to 15 years of age and were admitted to the hospital with a variety of symptoms. Those that presented with nausea, vomiting, and hypotension rapidly deteriorated and entered a coma. An autopsy was performed in all but one of the 16 cases reviewed. Macroscopically, the livers had a yellowish discoloration with petechial bleeding. Histopathologic examination revealed acute toxic hepatitis. In conclusion, these firecrackers are found in corner shops throughout Turkey, may cause death in children with little warning, and should be banned to prevent further deaths.     

镇静催眠药自杀中毒——附六例尸检报告

本文分析6例镇静催眠药急性中毒死亡的临床症状,法医学尸检和毒物分析资料。镇静催眠药中毒临床表现为昏迷、呼吸抑制、低血压、反射消失、周围循环衰竭等。病理变化以肺、肝、肾、脑等脏器较明显,肺淤血、水肿、肝细胞脂肪变性、肾近曲小管上皮细胞变性、脑水肿等。病变程度与服药至死亡时间长短有关,中毒死亡与药物剂量、个体差异、所患疾病及中毒后抢救所致的临床并发症等因素有关。

Molecular Pathology of Pulmonary Edema in Forensic Autopsy Cases with Special Regard to Fatal Methamphetamine Intoxication

Pulmonary edema is a common finding in fatal methamphetamine intoxication. However, the underlying mechanism remains poorly understood. This study investigated the molecular pathology of alveolar damage involving pulmonary edema in forensic autopsy cases. Seven candidate reference genes (RPL13A, YWHAZ, GUSB, SDHA, GAPDH, B2M, and ACTB) were evaluated in the lung by the geNorm module in qBase^plus software. RPL13A, YWHAZ, and GUSB were identified as the most stable reference genes. Using these validated reference genes, intrapulmonary mRNA expressions of matrix metalloproteinases (MMPs), intercellular adhesion molecule‐1 (ICAM‐1), claudin‐5 (CLDN‐5), and aquaporins (AQPs) were examined. Relative mRNA quantification using TaqMan real‐time PCR assay demonstrated higher expressions of all markers except for AQP‐5 in fatal METH intoxication cases. These findings suggested alveolar damage and compensatory response in fatal METH intoxication cases. Systematic analysis of gene expressions using real‐time qPCR is a useful tool in forensic death investigation.     

Fatal intoxication with 1,4-butanediol: Case report and comprehensive review of the literature

A fatal case of 1,4-butanediol (1,4-BD) oral ingestion is reported here, in which a 51-year-old man was found dead in his bed. According to the police report, the deceased was a known drug user. A glass bottle labeled (and later confirmed to be) “Butandiol 1,4” (1,4-BD) was found in the kitchen. Furthermore, the deceased's friend stated that he consumed 1,4-BD on a regular basis. The autopsy and histological examination of postmortem parenchymatous organ specimens did not revealed a clear cause of death. Chemical-toxicological investigations revealed gammahydroxybutyrat (GHB) in body fluids and tissues in the following quantities: femoral blood 390 mg/L, heart blood 420 mg/L, cerebrospinal fluid 420 mg/L, vitreous humor 640 mg/L, urine 1600 mg/L, and head hair 26.7 ng/mg. In addition, 1,4-BD was qualitatively detected in the head hair, urine, stomach contents, and the bottle. No other substances, including alcohol, were detected at pharmacologically relevant concentrations. 1,4-BD is known as precursor substance that is converted in vivo into GHB. In the synoptic assessment of toxicological findings, the police investigations and having excluded other causes of death, a lethal GHB-intoxication following ingestion of 1,4-BD, can be assumed in this case. Fatal intoxications with 1,4-BD have seldom been reported due to a very rapid conversion to GHB and, among other things, non-specific symptoms after ingestion. This case report aims to give an overview to the published of fatal 1,4-BD-intoxications and to discuss the problems associated with detection of 1,4-BD in (postmortem) specimens.     

A Fatal Case of CO2 Intoxication in a Fermentation Tank

Carbon dioxide (CO₂) is an odorless constituent of air. Higher concentrations can be detected in geothermal and automotive emissions, fermentation, and sublimation of dry ice. An unskilled worker entered a fermentation tank to clean it, which had not been done for about 5 months allowing for high concentrations of CO₂ to build up. A second worker entered the tank to rescue the first one. Shortly after both were found the first worker was rescued directly whereas the tank had to be rotated to pull the second worker out. Cardiopulmonary resuscitation was successful only for the first worker. Medico‐legal autopsy showed bruises, hematoma, myocardial hemorrhage, and edema of the lungs. The right lung was vacuum degassed in an argon atmosphere and quadrupole‐mass‐spectrometry showed an elevated CO₂ content in lung gases. Thus, CO₂ intoxication/asphyxia in a vitiated atmosphere due to fermentation of wine mash was established as the cause of death.
