Traumatic bilateral vertebral artery dissection

Traumatic vertebral artery dissection is not often seen by forensic pathologists, and cases investigated are scarce in the forensic literature. We present the case of a 40-year-old woman cyclist who was struck by a car while wearing a helmet, and was neurologically near normal immediately thereafter at Emergency. She presented 48 h later with acute right hemiparesis, decreasing level of consciousness, and unsteadiness. CT revealed massive cerebellar infarction. CT angiography was normal. The patient died in coma 7 days after injury and autopsy revealed bilateral edematous cerebellar infarction and bilateral vertebral artery dissection. Rotational neck injury and mural tear in the wall of the Atlantic parts of both vertebral arteries is suggested as the possible mechanism of the arterial injury. Head and neck injuries are reported as a precipitating cause of vertebral artery injury. The possible influence of trauma may be further underestimated if longer intervals between vessel dissection and ischemia occur. The current case illustrates that "talk-and-die" syndrome may be due to occult vertebral artery dissection, possibly bilateral. In forensic cases of delayed death after mild trauma to the head and neck, the vertebral arteries should be examined for the cause of death.     

Reporting a sudden death due to accidental gasoline inhalation

The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes.     

Correlates of Substantiated Emotional Maltreatment in the Second Canadian Incidence Study

The objective of this study was to determine the correlates of substantiated psychological maltreatment (PMT) in Canada on functions of maltreatment characteristics, child profile, household profile, and child protection services interventions. This study is based on a secondary analysis of data collected in the second Canadian Incidence Study. PMT investigations were categorized into six groups: emotional abuse, emotional neglect, and other maltreatment as single form, and these same three groups when they co-occurred with another form of maltreatment. Six logistic regressions, comparing all pairs of groups, were carried out. Cases of PMT (single form) were more chronic and associated with greater adverse emotional impact than other forms of maltreatment. Mothers of psychologically maltreated children had more mental health issues. Emotional neglect cases were more complex (e.g., substance abuse, mental health, and social housing). The three co-occurrent groups present more negative factors but more risk factors are observed when PMT are also observed (e.g., emotional harm, alcohol abuse, housing problems, chronicity, and referral to other services).     

Corporate governance and financial development: a study of the French case

This paper belongs to the growing body of the “Law and finance” literature based on time-series study. It carries out an empirical investigation of the role of corporate governance in financial development. We focus on French corporate governance reforms in order to examine whether these reforms are consistent with the reorganization of the French financial system, which took place during the period 1977–2004. This research aims at evaluating one proposition of the legal origin claims based on the idea that there is a strong and stable relationship between legal origin, investor protection and financial system. A key question the study addresses is how corporate governance rules and the French financial development have changed over time. Our study suggests that indicators related to investors’ rights (shareholders, employees, and bondholders) have been increasing over time, despite the specific legal origin of the French system. On the contrary the creditors’ rights have followed a less clear trend. Our econometric investigation is fairly new as the Law and finance literature has not until now provided corporate governance indicators suitable for French legislation. From that perspective, our work undergoes a multiple criteria analysis of corporate governance reforms. Following this approach, we suggest that the causality links between changes in the French legal environment and financial growth in France are more bidirectional than unidirectional.     

(Un)secured debt and the likelihood of court-supervised reorganization

Secured and unsecured creditors engaged in a bankruptcy process have different preference on the issue of financial distress. Secured creditors generally prefer liquidation whereas unsecured creditors tend to promote firm??s reorganization. As a consequence, secured creditors might be an obstacle to reorganization when all classes of creditors have to vote to approve the reorganization plan. To complete this analysis, we study the link between bankrupt firm??s capital structure and the likelihood of reorganization when bankruptcy Courts (instead of creditors) decide whether or not firms are reorganized. Our main result is that the reduction of secured creditors?? influence on the reorganization process might constitute a means to promote bankrupt firm??s reorganization. More generally, the paper analyses the link between the amounts/numbers of both secured and unsecured claims and the final issues of a Court-supervised reorganization process.     

Attention‐Deficit/Hyperactivity Disorder in Young French Male Prisoners

While forensic studies have reported higher than community rates of mental disorders in imprisoned populations, few studies have focused on attention‐deficit/hyperactivity disorder (ADHD) in these subjects. The aim of this study was to investigate ADHD prevalence among young French male prisoners. A specific diagnostic interview (Conners' Adult ADHD Diagnostic Interview for DSM‐IV, CAADID) was used. Correlations between ADHD, subsyndromal ADHD, and criminal features were investigated. 11% of young male prisoners among 93 male subjects aged 18–35 years met the criteria for actual ADHD, and 17% met those for childhood ADHD. Considering ADHD and subsyndromal ADHD, prevalence was about 43% in adulthood. ADHD and subsyndromal ADHD in adulthood were significantly associated with a higher number of imprisonments and a younger age at first arrest. It could be advisable to better identify subjects with ADHD symptoms among prison populations.     

Optimization of Human mtDNA Control Region Sequencing for Forensic Applications

Sequencing mitochondrial DNA hypervariable regions I and II (HVI and HVII) is useful in forensic missing person and unidentified remains cases. Improvements in ease and sensitivity of testing will yield results from more samples in a timely fashion. Routinely, amplification of HVI and HVII is followed by Sanger sequencing using the BigDye^® Terminator v3.1 Cycle Sequencing kit (Applied Biosystems) using 4 μL of ready reaction mix (RRM). Each sequencing reaction is then purified through column filtration before capillary electrophoresis. Using lower amounts of RRM (2 μL or 1 μL) and purification using BigDye^® XTerminator^? (Applied Biosystems) instead of columns showed no loss of sequence length and increased the quality and the sensitivity of testing, allowing HVI and HVII typing from mitochondrial genome equivalent to 125 fg of nuclear DNA, or 100 pg of HVI/HVII amplicons. Using this methodology, testing can be completed in 1 day, and the cost of testing is reduced.     

Acts of Intimate Partner Violence and Feelings of Danger in Battered Women Seeking Help in a Spanish Specialized Care Unit

Acts of violence recounted by 161 female victims of Intimate Partner Violence (IPV) attended at a psychological care service in Spain are presented. The relationship between acts of violence and feelings of danger, childhood abuse, and dyadic adjustment are analyzed. Reported acts of IPV were obtained through a Semi-structured Interview on Domestic Violence; and marital satisfaction was assessed with the Dyadic Adjustment Scale. The results showed women who have felt their lives were in danger are more likely to have been victimized. In addition, women who were both abused by their partner and sexually abuse as children are the ones that perceive more situations of danger in their adult couple relationship. The importance of studying perceived danger and the diversity of IPV experiences are discussed to aid prevention and intervention strategies.
