Delayed cardiac rupture due to blunt chest trauma

A 7-year-old boy fell from a 2.5-m height and suffered contusion of the thorax with hematoma in the soft tissues of the lateral chest wall. The rib cage itself remained intact. After 3 days, there was only local pressure sensitivity of the left hemithorax. On day 8 after the trauma, the child, who up to then had seemed to be in good health, suddenly died during lessons at school. Autopsy revealed a full-thickness rupture of the left ventricle with resultant cardiac tamponade. The macroscopic and histopathologic findings are presented and discussed.     

Sudden death due to delayed rupture of hepatic subcapsular hematoma following blunt abdominal trauma

Blunt abdominal trauma can cause sudden, unexpected death due to injuries to internal organs. Rupture of a hepatic subcapsular hematoma is a relatively rare cause of sudden death following minor blunt abdominal trauma. Death may be delayed several days to weeks. The autopsy is an invaluable diagnostic tool that can be utilized to uncover sudden deaths due to abdominal trauma. The case of an alcoholic who died of a ruptured hepatic subcapsular hematoma is presented. The death investigation revealed that the victim had sustained blunt abdominal trauma during a fall a few days prior to death.     

The relationship between trauma and violence in a jail inmate sample

Research suggests there is a link between trauma and violence, although the nature of the relationship is rather equivocal. This study explored this relationship by examining self-reported trauma as a predictor of self-reported violence in 93 jail inmates. Ninety-six percent of the sample reported experiencing a traumatic event, and 67% reported having been violent during the year preceding incarceration. Inmates reporting trauma were more than twice as likely to report having been violent than nonviolent. Stepwise multiple regression analyses suggested traumatic events, as a combined model, significantly contributed to violence perpetration. In addition, witnessing serious violence predicted perpetration of violence. Implications and limitations of the present study are discussed.     

Traumatic rupture of intracranial vertebral artery due to hyperextension of the head: reports on three cases

In three cases of fatal basal subarachnoid hemorrhage due to rupture of the normal intracranial vertebral artery, the ruptures appeared to have been caused by overstretching of the vertebral artery from traumatic hyperextension of the head. In the first case, that of a 31-year-old male pedestrian who, while intoxicated, had been hit from behind by a car, symmetrically located bilateral complete and incomplete tearing of the vertebral arteries was found. In both of the other two cases, involving women aged 37 and 51 found dead after receiving fist blows to the face while intoxicated, complete rupture of the vertebral artery was found. The blood alcohol concentrations of the three cases ranged from 1.6 to 1.7 mg/g at autopsy.     

Blunt basal head trauma: rupture of posterior inferior cerebellar artery.

Two cases are reported of rupture of posterior inferior cerebellar artery (PICA) from blunt basal head trauma. The anatomy at the site of rupture is discussed as a prerequisite for rupture. The rapid fatal course is also discussed. The authors propose that the forensic term "traumatic subarachnoid haemorrhage" ought to be abandoned and replaced by the nature and localization the source of bleeding, analogous to clinical practice at the spontaneous haemorrhage from rupture of aneurysm.

Biomechanism of intracranial and spinal trauma of child born in occipitoanterior presentation as used in forensic examination

The new conception of mechanism and sequence of damages typical for labor trauma is presented: injury of ligaments of atlas and axis and anterior atlanto-occipital membrane, ruptures of synchondrosises of cranial bones because of vertebral column pressing on occipital bone; tears of dura mater of brain upon basilar impression in the area of focal spot; subarachnoid hemorrhage and intracerebral bleeding in case of cerebral compression by bone borders where they overly override; ruptures of ligaments of cervico-occipital and intervertebral joints in case of excess flexion and overextension of head. Authors show that damage of sutures, bones of calvarium and partition parts of dura materialize later than injury of synchondrosises of base and they are absent if sinchondrosises are not damaged. Also iatrogenic damages of fetal in labor and the mechanism of their formation are described.     

The correlation between skull fractures and intracranial lesions due to traffic accidents

In this study, it was aimed to investigate the relationship between skull fractures and intracranial lesions following head injury. For this purpose, 500 cases, which were referred to the Third Committee of Council of Forensic Medicine in Istanbul due to traffic accidents by the courts of laws between 1998 and 2000, were examined retrospectively. They were categorized in 3 groups based on findings of their cranium x-rays and brain tomographies. 1- The cases who have fractures in skull bones with brain lesions 2- The cases who have fractures in skull bones with no brain lesions 3- The cases who have brain lesions with no skull fractures. They were examined in detail according to age, sex, localization of skull fractures and brain lesions, and if surgery was applied or not.Of the cases, 152 (30.4%) had only linear fractures, 69 (13.8%) had depressed fractures, 92 (18.4%) had linear fractures plus intracranial lesions, 49 (9.8%) had depressed fractures plus intracranial lesions and 138 (27.6%) had only intracranial lesions. The rate of intracranial lesion among the cases with the skull fracture was 38.9% (141/362), while the rate of skull fracture among the cases with the intracranial lesion was 50.3% (141/279) (P < 0.001). Male to female ratios were 2.4/1 for linear fractures, 5.2/1 for depressed fractures, and 3.5/1 for intracranial lesions. Linear fractures were more frequent among females whereas depressed fractures were often among males (chi2: 9.68, df: 4, p: 0.046). The mean age was 26.3. The rate of depressed fractures was higher the age groups of 0-30 years. (chi2: 16.28, df: 4, p: 0.003). Depressed fractures in the regions of frontal and parietal and, linear fracture in the regions of temporal and occipital were found at higher rates (P < 0.001).In conclusion, we reviewed skull fractures and/or intracranial lesions due to traffic accidents, and found depressed fractures to be more common among males whereas linear fractures to be more common among females and young males. In the male, the skull architecture is thicker and stronger than females and young males. We can state that presence of skull fractures lowers the incidence of intracranial lesions by lowering the intracranial pressure.

The biology of trauma: implications for treatment

During the past 20 years, the development of brain imaging techniques and new biochemical approaches has led to increased understanding of the biological effects of psychological trauma. New hypotheses have been generated about brain development and the roots of antisocial behavior. We now understand that psychological trauma disrupts homeostasis and can cause both short and long-term effects on many organs and systems of the body. Our expanding knowledge of the effects of trauma on the body has inspired new approaches to treating trauma survivors. Biologically informed therapy addresses the physiological effects of trauma, as well as cognitive distortions and maladaptive behaviors. The authors suggest that the most effective therapeutic innovation during the past 20 years for treating trauma survivors has been Eye Movement Desensitization and Reprocessing (EMDR), a therapeutic approach that focuses on resolving trauma using a combination of top-down (cognitive) and bottom-up (affect/body) processing.     

The relationship of jail population to operating costs in southern county jails

The cost of providing correctional services has been soaring in recent years, reaching a figure of $72.9 million for counties in eight southern states in 1974. Prisoner populations in these county jails ranged from one to 653. Such large outlays by small and often poorly financed governmental bodies combined with the apparent variations in jail size suggest that evidence concerning the relationship between scale of operation and average variable cost might be of significant value to local decision-makers.This paper begins with a review of previous work related to economies of scale in the public sector to provide a basis for understanding the costs associated with local jails. It proceeds to the development of a theory of the factors which affect operating costs in southern county jails—including scale of operation. These factors are then incorporated in a multiple-regression model of average variable cost. The findings indicate that approximately 90 percent of the variation in operating cost per prisoner is explained by the several independent variables of which wages, security and technology are statistically significant. Since jail size has no significant effect on operating cost per prisoner, a horizontal average variable cost curve is implied and no net economies of scale are revealed.     

The efficacy of a classification system: Its relationship to resource-procedure management

The efficient and effective operation of an organization is of major concern to any manager. For those managers responsible for service organizations, especially in the public sector, this is especially true due to the scarcity of resources. Lacking the capacity to manage resource-procedure interactions through the use of inventory, other methods must be found and used.One approach toward efficient management is to segment service users in order to identify the most appropriate resource-procedure interaction. In this study, a correctional agency that segmented its service users (offenders) by using a classification system was analyzed. It was found that even though a sophisticated classification system was in place, other elements necessary for the efficient and effective management of resource-procedure interactions were not present.     

Linking crime rates to relationship factors: The use of gender-specific data

The present study built on, and extended beyond, Steffensmeier and Haynie's efforts (2000) to understand social control factors at the macro level. It focused especially on gendered relationship factors as predictors of gender-disaggregated arrest rates for serious adult crimes. There are two aspects of social control that function to discourage crime: structural factors and relationship factors. Most previous studies had focused on the former aspect, examining the effects of a locale's structural disadvantages on its gender-disaggregated crime rates. In the present study, the authors addressed the latter aspect, in particular, the kinds of relationship factors built on marriage and employment. The evaluation was conducted using data recorded by the national census, the State of Ohio's Boards of Elections, and the FBI's Uniform Crime Reports for Ohio. The developed negative binomial regression models illustrate the general hypothesis that women and men residing in a common ecological area are not equally subject to relationship factors that help control criminal behavior. Women tend to be affected more strongly by such factors than men are.     

The relationship of imagery and mental practice to learning law enforcement skills

Visualization and mental rehearsal/ practice have beem empirically evaluated in the athletic area for many years and found to be viable forms of performance enhancement. Gross motor skills and certain psychological/physiological dysfunctions are also susceptible to improvement through use of these techniques. A general overview of these concepts is presented as well as potential applications in the law enforcement context.
