a prospective assessment of the accuracy of commercial igm elisas in diagnosis of japanese encephalitis virus infections in patients with suspected central nervous system infections in laos.	japanese encephalitis virus (jev) is a major cause of encephalitis in asia. we estimated the diagnostic accuracy of two anti-jev immunoglobulin m (igm) enzyme-linked immunosorbent assays (elisas) (panbio and xcyton jevchex) compared with a reference standard (afrims jev mac elisa) in a prospective study of the causes of central nervous system infections in laos. cerebrospinal fluid (csf; 515 patients) and serum samples (182 patients) from those admitted to mahosot hospital, vientiane, were teste ...	0	22764310
spatial distribution and risk factors of dengue and japanese encephalitis virus infection in urban settings: the case of vientiane, lao pdr.	to evaluate the prevalence of flavivirus infection in vientiane city (lao pdr), to describe the spatial distribution of infection within this city, and to explore the link between flavivirus seroprevalence and urbanization levels of residential neighbourhoods.	2009	19563430
epidemiological study of japanese encephalitis virus in vientiane, lao pdr, in 1990s.	phylogenetic analysis of japanese encephalitis virus (jev) was conducted using core-premembrane and envelope gene sequence data of two strains from vientiane, lao people's democratic republic, in 1993 and five from okinawa, japan, in 2002 and 2003, and previously published strains. the two vientiane strains designated as lavs56 and lavs145 belonged to genotype 1 (g1) and the same subcluster of g1 as australian strain in 2000, thai strains in 1982-1985 and 2004-2005, and vietnamese strain in 2005 ...	2015	25695095
the aetiologies and impact of fever in pregnant inpatients in vientiane, laos.	laos has the highest maternal mortality ratio in mainland southeast asia and a high incidence of infectious diseases. globally, malaria has been the pathogen most intensively investigated in relation to impact on pregnancy, but there has been relatively little research on the aetiology and impact of other diseases. we therefore aimed to determine the causes and impact of fever in pregnant women admitted to two central hospitals in vientiane city, lao pdr (laos).	2016	27050192
pre-cut filter paper for detecting anti-japanese encephalitis virus igm from dried cerebrospinal fluid spots.	the use of filter paper as a simple, inexpensive tool for storage and transportation of blood, 'dried blood spots' or guthrie cards, for diagnostic assays is well-established. in contrast, there are a paucity of diagnostic evaluations of dried cerebrospinal fluid (csf) spots. these have potential applications in low-resource settings, such as laos, where laboratory facilities for central nervous system (cns) diagnostics are only available in vientiane. in laos, a major cause of cns infection is ...	2016	26986061
