Asphyxia, not an uncommon cause of sudden death, may result from numerous etiologies. Foreign-body aspiration and strangulation are 2 extrinsic causes. Airway obstruction may also be caused by laryngeal edema, asthma, infection, or anaphylaxis. Chronic causes of asphyxia include musculoskeletal diseases (eg, muscular dystrophy, amyotrophic lateral sclerosis), neurologic disorders (eg, myasthenia gravis, multiple sclerosis), respiratory disease (eg, emphysema, chronic bronchitis), or tumors. The manner of death in cases of asphyxiation may be natural, accidental, homicide, or suicide. For the death investigator, determining the cause and manner of death can often be quite challenging.We report here 2 cases of an esophageal fibrovascular polyp causing sudden asphyxial death, review of the literature, and discussion of other differential diagnoses in the case of asphyxial death.  相似文献

Presidency scholars suggest that the federal bureaucracy has become presidentialized and that the federal agencies have become a primary tool for presidential policy implementation. However, in its review of federal agency litigation, the Supreme Court stands as an important monitor of executive bureaucratic action. Here, the conditions under which Supreme Court justices choose to facilitate executive bureaucratic action are assessed. This study tests the proposition that Supreme Court justices' voting decisions to support the president's bureaucratic agents are conditioned upon theoretically interesting extra-legal factors. Logistic regression analysis was conducted on justices' votes from Supreme Court cases involving cabinet and independent agencies during the years 1953–1995. The results indicate that Supreme Court justices' voting decisions to favorably review bureaucratic actions are influenced by extra-legal factors including attitudinal, political, and external concerns.  相似文献

This study assessed the associations of characteristics of domestic violence incidents with clinically significant levels of traumatic symptoms and behavioral problems in a socio-economically and ethnically mixed sample of 687 children participating in a community-service program for children witnessing violence. Study predictors included child/family demographic characteristics, type and chronicity of exposure, and child’s perceptions of control over the event and threat to personal safety. Outcomes consisted of traumatic symptoms and behavior problems. Results showed that perceived threat and control were associated with greater odds of clinically significant levels of several trauma symptoms (and behavior problems in the case of perceived threat) after adjusting for effects of demographic factors and violence characteristics. Child co-victimization increased odds of reaching clinically significant levels of traumatic symptoms compared to children who witnessed the event but were not victimized. Female sex and White ethnicity increased odds of specific trauma symptoms and behavior problems. Increasing age reduced odds of some trauma symptoms. Associations between predictors and one outcome measure did not generalize across the other outcome measure. Implications of study findings, and directions for future research are discussed.  相似文献

Discharge planning is increasingly prioritized by correctional systems in order to prepare prisoners for their reintegration into society. A goal of discharge planning is to link prisoners with appropriate service providers in the community to meet their needs. A successful discharge plan requires that an optimal level of services exist and work in a coordinated and collaborative way in order to ensure a continuum of care and treatment during the reentry process (Queralt & Witte, 1999). This study utilized Geographic Information System (GIS) to assess the size, demographic characteristics, and needs of the Newark, New Jersey parolee population with the availability, location, and characteristics of health and human service agencies servicing their needs. A random sample of parolees (N = 800) released in 2006 was selected for this study. Social service agency data were obtained from an on-line service agency data base. Results of the analysis include the degree of spatial distribution, accessibility, and availability of services to where the parolees live and the degree of spatial overlap of specific services in an area.  相似文献

The causal factors associated with increases in depressive symptoms among adolescent girls remain an area of theoretical debate, and the limited research considering a hormonal influence has provided mixed results. The goal of the present study was to test a set of longitudinal associations, that, if found, would provide support for a hormonal contribution to these changes. Specifically, this study tested the hypotheses that changes in depressive symptoms among adolescent girls would be associated with phase-specific symptoms of the menstrual cycle during early adulthood; that these associations would differ across three phases of the menstrual cycle; and that the pattern of associations would differ for changes in depressive symptoms during early- and late-adolescence. The sample consisted of 47 women with longitudinal data from 12 to 21 years old (approximately 91% European Canadian, 4% Middle Eastern Canadian, 2% Haitian Canadian, and 2% Asian Canadian). Consistent with expectations, results showed that early-adolescent increases in depressive symptoms were negatively associated with menstrual-phase negative affect, and positively associated with mid-cycle negative affect, but not associated with premenstrual negative affect; whereas late-adolescent change in depressive symptoms was only associated with depressive symptoms at 20-21 years. Thus, early-adolescent changes in depressive symptoms are longitudinally associated with later mood change across the menstrual cycle, suggesting a common underlying cause, which is hypothesized to be hormonal. Moreover, results suggest that, with respect to variables that are involved in affective development, important differences exist between early- and late-adolescence. The discussion considers menstrual-cycle-related symptoms (e.g., dysmenorrhea) during adolescence, and the need to study their effects on development. It is suggested that focused intervention and prevention efforts may be indicated to interrupt negative developmental outcomes.  相似文献
