West Nile virus (WNV) is a mosquito-borne virus that has caused a large number of deaths in the United States since the first outbreak in New York City in 1998. The outbreak initially was limited to the northeast but has since spread across the entire continental United States. WNV causes a variety of clinical symptoms, but the most severe consequences result from central nervous system infection, resulting in meningitis, encephalitis, or meningoencephalitis. We present a case of a 62-year-old male with metastatic cancer, who died as a result of WNV encephalitis. This is followed by a discussion on the epidemiology of WNV and a detailed summary of the methods and resources available to make a diagnosis of WNV infection postmortem. The material presented in the discussion should provide the forensic pathologist with all the information necessary to make a diagnosis of WNV infection postmortem. If nothing else, the routine collection and storage of serum, cerebrospinal fluid, and tissue for every case can enable the forensic pathologist to make this diagnosis even in cases in which WNV is not suspected until after autopsy. 相似文献

This article explores the possibilities for new forms of ‘digital citizenship’ currently emerging through digitally supported processes of narrative exchange. Using Dahlgren's (Dahlgren, P. 2003. “Reconfiguring Civic Culture in the New Media Milieu.” In Media and the Restyling of Politics, edited by J. Corner, and D. Pels, 151–170. London: Sage; Dahlgren, P. 2009. Media and Political Engagement. Cambridge: Cambridge University Press.) circuit of ‘civic culture’ as a model for exploring the interlinking preconditions for new acts of citizenship, we discuss the contrasting outcomes of research at three fieldwork sites in the North of England – educational (a sixth form college), civil society (a community reporters' network) and social (a local club). Each site provided clear evidence of the elements of Dahlgren's circuit (some depending on the intensive use of digital infrastructure, others predating it), but there were also breaks in the circuit that constrained its effectiveness. A crucial factor in each case for building a lasting circuit of civic culture (and an effective base for new forms of digital citizenship) is the role that digital infrastructure can play in extending the scale of interactions beyond the purely local. 相似文献
