Skull Fracture with Brain Expulsion in a One-Level Jumping-Fall

Abstract:  Here presented is the case of a one-level jumping-fall with extensive skull fractures and brain expulsion. The body was found on the basement floor at the foot of the stairs. At the autopsy, the skull was extensively fractured, with about half of the brain expulsed several feet away from the body. The cause of death was established as a craniocerebral trauma with brain expulsion. The circumstances and manner of death were still unclear at that time. A low fall seemed very unlikely considering the severity of the skull and brain damage. The police investigation clearly revealed that the man, in a paranoid psychotic state, attacked his wife with a knife and then was witnessed by his children to have hit his head several times with a hammer. Afterwards, they saw him running to the top of the basement stairs and jumping to the bottom of the stairs head first.     

Macroscopic Analysis of Axe and Hatchet Trauma in Fleshed and Defleshed Mammalian Long Bones*

Abstract: Recently, the authors have noted that many studies involving the characterization of chopping weapon wounds have used either semi‐fleshed or defleshed bones (e.g., J Forensic Sci 2001; 46: 228). As these types of specimens do not reflect the full range of actual cases of postmortem dismemberment or perimortem trauma, 11 fresh pig (Sus scrofa) articulated hind limbs, with contiguous surrounding flesh, were inflicted with wounds using two axes and two hatchets. Defleshed humeri and femora were subjected to the same treatment. While there were no great differences found between the fleshed and defleshed specimens, characteristics observed including entrance site width and the presence of chattering were inconsistent with some aspects of Humphrey and Hutchinson’s study (J Forensic Sci 2001; 46: 228). Further, it was found that curve transverse and spiral fractures were prevalent in femora, while longitudinal fractures were prevalent in fibulae. Hence, fracture types may play a role in characterizing some wounds caused by chopping weapons.     

Trauma Resilience Training for Police: Psychophysiological and Performance Effects

The objective of this study is to test the effects of police trauma resilience training on stress and performance during a critical incident police work simulation. Rookie police officers (N = 18) participated in a randomized trial of a 10-week imagery and skills training program versus training as usual. Twelve months later, psychophysiological stress and police work performance were assessed during a live critical incident simulation. Training resulted in significantly less negative mood, less heart rate reactivity, a larger increase in antithrombin, and better police performance compared to controls. Trends for cortisol and self-reported stress also suggested benefits of training. This novel training program is a promising paradigm for improving police well-being, stress resiliency, and optimizing job performance.     

Adverse Childhood Experiences and Subsequent Substance Abuse in a Sample of Sexual Offenders: Implications for Treatment and Prevention

The purpose of this study was to explore the prevalence of substance abuse indicators in a sample of male sexual offenders (N = 679) and to examine the influence of adverse childhood experiences (ACE) on the likelihood of substance abuse outcomes. Half of these sex offenders reported a history of drug or alcohol abuse, and nearly one in five reported a substance-related arrest. Higher ACE scores were associated with endorsement of a greater number of substance-abuse-related problems, suggesting that accumulation of early trauma may increase the likelihood for substance misuse. By enhancing our understanding of the frequency and antecedents of dynamic risk factors such as substance abuse, we can better devise clinical interventions that respond to the comprehensive needs of sexually abusive individuals and reduce risk for sexual reoffense. As well, early interventions for at-risk families and maltreated youth may interrupt their trajectory toward adulthood substance abuse and criminal behavior, including sex offending.     

Conceptualizing the Harms Done to Children Made the Subjects of Sexual Abuse Images Online

The innovation of the Internet and the proliferation of new digital technologies in everyday life have unfortunately created more opportunities for the sexual abuse of children and especially the global distribution of child sexual abuse images online (CSAIO). Most of the current therapeutic interventions being used were designed to treat ‘conventional’ sexual abuse trauma. Victims of CSAIO may experience ongoing trauma because the recordings of their abuse have the potential to be endlessly viewed and shared by those with a sexual interest in children some of whom may be known to them. However, little is known about the potential psychological harm to victims, the extent to which existing trauma treatment modalities are applicable to them, or what modifications of these treatments may be required for effective treatment. This paper explores current ways of understanding the harms done to the victims of CSAIO and presents cautions and recommendations for moving forward.

颅脑损伤后心内膜下出血的病理及心电图改变

研究颅脑损伤后心内膜下出血的病理改变及其法医学意义。利用68例颅脑损伤的尸检和临床病历资料,以及相应心内膜下出血的心脏标本,以病理组织学方法观察心肌损害,分析心电图异常图形。结果显示：早期主要为左心室内膜下新鲜出血,浅层心肌出血,心肌散在灶状变性、横纹消失等心肌缺血性改变。晚期主要为以多形核白细胞为主的浸润,成纤维细胞增多,早期心肌瘢痕形成等心肌梗死样改变。21倒心电图异常以窦性心动过速和ST-T改变为主,严重的出现心律紊乱和房室传导阻滞。研究颅脑损伤后心内膜下出血的病理改变和心电图异常,在法医学实际检验鉴定和临床救治方面有重要的应用价值。
