Animal-related fatalities--part II: characteristic autopsy findings and variable causes of death associated with envenomation, poisoning, anaphylaxis, asphyxiation, and sepsis

In addition to blunt and sharp trauma, animal-related fatalities may result from envenomation, poisoning, anaphylaxis, asphyxiation, and sepsis. Although the majority of envenomation deaths are caused by hornets, bees, and wasps, the mechanism of death is most often anaphylaxis. Envenomation resulting from the injection of a poison or toxin into a victim occurs with snakes, spiders, and scorpions on land. Marine animal envenomation may result from stings and bites from jellyfish, octopus, stonefish, cone fish, stingrays, and sea snakes. At autopsy, the findings may be extremely subtle, and so a history of exposure is required. Poisoning may also occur from ingesting certain fish, with three main forms of neurotoxin poisoning involving ciguatera, tetrodotoxin ingestion, and paralytic shellfish poisoning. Asphyxiation may follow upper airway occlusion or neck/chest compression by animals, and sepsis may follow bites. Autopsy analysis of cases requires extensive toxinological, toxicological, and biochemical analyses of body fluids.     

A proposed dissection procedure for vertebral arteries in forensic pathology

Vertebral artery removing constitutes a significant forensic pathology challenge. Dissection techniques during head-neck autopsy are based on anterior approach, a difficult method, which is unable to assess the transverse part of the artery. This work presents an original and simple method for dissecting vertebral arteries by a posterior approach, opening the vertebroarterial canal through the spinal canal without any special equipment. Once the spinal cord is removed, the transversarium foramens are opened by an internal cut at the pedicle and an external cut at the transverse process. This enables us to visualize vertebral arteries in its entirety. The method improves both the examination of the upper extracranial segment of the vertebral artery and the neuropathological study when arterial injury is suspected. Applying this method routinely is both feasible and useful in suspected cases of vertebral artery trauma and could contribute to assess more precisely the actual incidence of this injury.     

Multiple Self‐Inflicted Stab Wounds to Neck,Chest and Abdomen as a Unique Manner of Suicide

Abstract: This is a case report of a 30‐year‐old man found dead in his flat lying on the floor with multiple stab wounds over the body, surrounded by an extensive volume of blood. Examination of the scene of death showed a secure flat, locked from inside. A blood‐stained knife was present close to the body and two unstained notes left on the sofa at the locus. A small plastic bag containing white powder (which following toxicological examinations appeared to be cocaine) and an almost full bottle of beer were present on a table. Autopsy revealed more than 40 stab wounds to neck, chest, and abdomen arranged in isolated groups within which the wounds showed similar directions and had a transverse orientation. Together with hesitation marks located on the neck and wrists these characteristics allowed to interpret this case as a suicide.     

Caspase3和iNOS在人挫伤脑组织中的时序性表达

目的研究人脑挫伤后不同时间半胱氨酸天冬氨酸蛋白酶3（caspase3）和诱导型一氧化氮合酶（inducible nitric oxide synthase,iNOS）表达的变化,为法医实践中脑损伤时间的推断提供依据。方法选择30例因颅脑损伤死亡案例为损伤组,5例非颅脑损伤急死的案例为对照组,应用免疫组织化学和图像分析技术,分别于死亡后2h、4～8h、10～14h、1～2d、3～5d及8～11d检测脑组织标本中caspase3和iNOS的变化规律。结果经统计学分析：（1）caspase3阳性细胞表达在伤后2h以内组开始升高,与对照组相比差异有统计学意义（P〈0.05）,1～2d组表达强度增高,3～5d组仍见高表达（P〈0.05）,以后逐渐下降。（2）iNOS阳性细胞表达在2h以内组与对照组比较差异无统计学意义（P〉0.05）,伤后4～8h开始升高（P〈0.05）,1～2d组表达强度最高,以后逐渐下降,伤后8～11d仍有弱表达（P〈0.05）。结论caspase3和iNOS的表达可能成为实际检案中脑损伤时间推断的有效依据。

眼损伤图形刺激对比度视诱发电位

目的研究眼损伤者对比度视诱发电位的特征。方法选取本中心行法医临床学鉴定的60例眼损伤者,根据最佳矫正视力分为0.2~0.3(A组)、0.3~0.5(B组)、≥0.5(C组)三组。分别观察100%、25%、10%对比度条件下的对比度视诱发电位波的振幅及潜伏期变化特征,并行统计学分析。结果 (1)相同对比度时,P_(100)波振幅随刺激视角的减小而降低;(2)相同刺激视角时,P_(100)波振幅随对比度降低而降低,组间差异有统计学意义(P0.05);(3)100%、25%对比度时,相同刺激视角(100%7′视角除外),A组与B组差异无统计学意义(P0.05);A组与C组、B组与C组随视力提高,P_(100)波振幅增高(P0.05);10%对比度15′刺激视角,P_(100)波振幅随视力提高而增高(P0.05);(4)相同对比度下,相同刺激视角时,P_(100)波潜伏期随视力提高而缩短,但组间差异无统计学意义(P0.05)。相同刺激视角时,随对比度降低,P_(100)波潜伏期延长,但差异无统计学意义(P0.05)。结论对比度视诱发电位有望成为评估对比度视力的方法之一。     

CBS在脑挫伤后损伤时间推断中的作用

目的观察胱硫醚β合成酶(cystathionineβ-synthase,CBS)在脑挫伤后皮质中不同时段的表达变化。方法利用改良的自由落体装置建立小鼠脑挫伤模型,通过Western印记法和免疫组织化学方法检测不同时间点(1 h、6 h、12 h、1 d、2 d、3 d、7 d)损伤区周围皮质CBS的表达变化。结果 Western印迹法显示,CBS在脑损伤后皮质中的表达下调,在损伤3 d时降到最低,于损伤7 d恢复到正常水平。免疫组织化学结果显示,CBS在正常皮质中有表达,损伤后表达逐渐减弱,损伤3 d后阳性表达明显减少,7 d恢复到正常水平。结论 CBS有望成为法医学推断脑挫伤后损伤经过时间的参考指标。     

Crime: The amount and disparity of sentencing – A comparison of corporate and occupational white collar criminals

Research carried out previously, aimed at examining differences in the length of the sentencing and type of offence, have typically compared white collar and street criminality. The main aim of the current study is to examine the differences in sentence length for white collar occupational and corporate offenders from street crime offenses and to identify which factors eventually could explain such differences. The crime amount was smaller in occupational convictions despite the fact that the average crime amount was significantly less in this group compared to the crime amount among corporate criminals. Socioeconomic status and company size were not found to be associated with the length of the sentence. We discuss whether the difference in length of the sentence could be explained by the fact that occupational crime is committed for the criminals' own purposes or enrichment, while this is often not the case among corporate criminals.
