A lateral radiograph of the cervical spine was obtained for 174 of the 207 persons killed in road crashes in Adelaide, South Australia, during the 12-month period of June 1, 1987 to May 31, 1988. Of the total of 57 cases of cervical injury, routine postmortem examination identified 30 cases (52.6%), and the radiographic examinations identified 51 cases (89.5%). In the cases where it was performed, radiography identified 96.2% of injuries. One-half of injuries of level C3 and above were not reported at postmortem examination, compared with 22% of those occurring below this level. This finding correlates with the physical difficulties of examining the upper part of the cervical spine. This study has shown that lateral cervical radiography is a simple and effective method of more accurately identifying significant cervical spinal injuries, thus improving greatly the value of postmortem examinations in determining the patterns and mechanisms of these injuries. 相似文献

Resuscitation and petechiae 总被引:3,自引:0,他引:3
Petechiae can be important corroborative evidence of asphyxia, but are also seen in persons who have died of other means. It is not uncommon to encounter them in cases in which cardiopulmonary resuscitation has reestablished blood flow and pressure in small vessels already damaged by hypoxia resulting in the formation of petechiae. This report documents some representative cases. 相似文献

The need to measure qualitative outcomes is well documented. This article argues that despite this recognition many programs are still evaluated using unreliable numerical indicators. This has particular ramifications for community service programs that deal with the sharp end of social problems. While the New Zealand government has instigated a comparatively detailed approval standards, the Queensland government's community service guidelines are still applied almost on an ad hoc, case by case basis. Both New Zealand and Queensland performance indicators are directed towards process outputs, with a primary focus of government being centred on financial accountability. The satisfaction of the client remains the core responsibility of the service provider, but there is little assessment of how successful programs are in meeting individual requirements. This article suggests that there needs to be the development of a more collaborative relationship between governments and community service organisations, to ensure both financial and social objectives are fully realised. 相似文献

All deaths ascribed to asthma in the 5-to-40-year age group at the Wayne County Medical Examiners' Office were reviewed from 1975 to 1987 inclusive. Fifty-eight deaths were attributed solely to asthma, and the annual number increased fivefold in the 1980s to a rate of approximately 0.5 per 100,000 per year when extrapolated to the Wayne County population. Blacks were overrepresented to double their proportion in the general population. Almost all cases were known asthmatics, and many had received previous emergency care. Most fatalities occurred at night and did not demonstrate any seasonal variation. The onset of the fatal attack was apparently very rapid in most cases, with many engaged in routine activities and few surviving any length of time in hospital or having sought treatment earlier. Our data reveal a significant increase in sudden death in previously well asthmatics in Wayne County in the 1980s. Similar increases in deaths as a result of asthma have been noted previously in other countries for reasons that remain unclear. 相似文献

As collaborative approaches to resolving public disputes become more prevalent, agency officials are finding themselves in unfamiliar terrain. This article offers one conceptualization of agency roles in collaborative processes, drawing from the experiences of natural resource managers and enviromental regulators at the federal level. Based on an examination of 65 cases, the authorsidentify three distinct "hat" that effective agency officals wear in collaborative processes - leader, partner, and stakeholder. The objective and function of each role is assessed, along with the implications of agency facilitation. The most successful agency representatives were able to blend the three primary roles, and did not act as facilitators of the collaborative process. 相似文献

Once popular state-centred political frameworks, while declining in popularity on many normative agendas, nevertheless continue to guide how we think about and examine policing. Early studies into the private policing phenomenon have thereby focused upon the formal paid private security sector, a set of agencies which do not depart too radically in appearance from traditional public police services. More recent empirical studies have yielded data inconsistent with the established conceptual frameworks. Theorists have been assembling these data into alternate ways of thinking about collective life, which may have profound implications for the ways in which to choose to govern in the future. Further research addressing developments in networked nodal governance may be suggestive of progressive alternatives. 相似文献
