A 14-year-old boy with infectious mononucleosis died unexpectedly in hospital. The most significant finding at autopsy was the presence of marked bilateral tonsillar enlargement with considerable narrowing of the upper airway. There were no other underlying organic diseases that could have caused or contributed to death. Narcotic analgesia had been administered less than 2 h before death and may have contributed to respiratory compromise. The blood morphine level was 0.08 mg/L. Toxicological evaluation of individuals with obstructive lesions of the upper airway may, therefore, be a useful adjunct to the autopsy assessment of such cases as it may reveal factors exacerbating mechanical blockage. 相似文献

This article reports on data from a small pilot survey evaluating the compliance of voluntary databases in respiratory medicine with privacy laws and the National Health and Medical Research Council's National Statement on Ethical Conduct in Research Involving Humans. The increasing complexity of privacy law, including the recent private sector amendments, creates many challenges for database administrators. The impact of privacy laws upon voluntary or non-statutory databases, and upon doctors reporting patient data to such databases, is far from straightforward. The article suggests way in which the law might be adapted in order to better facilitate the role of voluntary data registers in health research and public health surveillance, while still protecting the privacy of patient information. The article also briefly considers how database administrators might "future-proof" their existing data holdings to ensure compliance with legal and ethical standards. 相似文献

The ability to accurately determine the number of syringe needle penetration holes through the rubber stoppers in pharmaceutical vials and rubber septa in intravenous (i.v.) line and bag ports has been a critical factor in a number of forensic cases involving the thefts of controlled substances or suspected homicide by lethal injection. In the early 1990s, the microscopy and microanalysis group of the U.S. Food and Drug Administration's Forensic Chemistry Center (FCC) developed and implemented a method (unpublished) to locate needle punctures in rubber pharmaceutical vial stoppers. In 1996, as part of a multiple homicide investigation, the Indiana State Police Laboratory (ISPL) contacted the FCC for information on a method to identify and count syringe needle punctures through rubber stoppers in pharmaceutical vials. In a joint project and investigation using the FCC's needle hole location method and applying a method of puncture site mapping developed by the ISPL, a systematic method was developed to locate, identify, count, and map syringe punctures in rubber bottle stoppers or i.v. bag ports using microscopic analysis. The method requires documentation of punctures on both sides of the rubber stoppers and microscopic analysis of each suspect puncture site. The final result of an analysis using the method is a detailed diagram of puncture holes on both sides of a questioned stopper and a record of the minimum number of puncture holes through a stopper. 相似文献

Academic scholarship displays a curious disconnect between two trends, connecting peace and governance issues. At the same time when conflicts tended to shift inwards (from inter-state to civil wars), global governance approaches seemed to decentre the management of peace and conflict outwards (from the nation state to international forums). This paper investigates this disjuncture by examining the European Union and India's governance strategies in different conflict contexts. It studies whether their strategies operate close to the global governance model and/or whether they are able to connect with and effectively support local peace initiatives in conflict-ridden areas. 相似文献
