A large-scale cross-sectional seroprevalence study of dengue (DEN) and Japanese encephalitis (JE) was conducted in Khammouane province, Lao PDR, as part of the initial baseline health impact assessment of the Nam Theun 2 hydroelectric dam construction project. Health surveys were performed between May 2007 and February 2008 with serum samples collected from healthy individuals involved in the resettlement program of 16 villages (total surveyed population 4,369). Hemagglutination inhibition assay using flavivirus antigens (DENV1, DENV3, and JEV) performed on 1,708 plasma specimens revealed 30.4% (519) cross-reactive positives, and 10% (172) and 1.3% (22) positives to JEV or DENV, respectively. Entomological surveys conducted during the rainy season of 2008 indicated the presence of competent flavivirus vectors (Culex vishnui group and Aedes albopictus), although Aedes aegypti was not found. Continued surveillance and investigation is warranted to assess the clinical disease burden of flaviviruses in this area that is undergoing rapid ecological and demographic change. 相似文献

We assessed risk factors for vectors of dengue and chikungunya viruses near a new hydroelectric project, Nam Theun 2, in Laos. Immature stages of Aedes aegypti were found only in sites within 40 km of the urban provincial capital, but Aedes albopictus was found throughout. Aedes aegypti pupae were most common in water storage jars (odds ratio [OR] = 4.72) and tires (OR = 2.99), and Ae. albopictus pupae were associated with tires in 2009 (OR = 10.87) and drums, tires, and jars in 2010 (drums OR = 3.05; tires OR = 3.45, jars OR = 6.59). Compared with water storage vessels, containers used for hygiene, cooking, and drinking were 80% less likely to harbor Ae. albopictus pupae in 2010 (OR = 0.20), and discarded waste was associated with a 3.64 increased odds of infestation. Vector control efforts should focus on source reduction of water storage containers, particularly concrete jars and tires. 相似文献

A 28-year old Malay man with evidence of an upper motor neuron cord lesion was diagnosed to have a C7 to T2 spinal arterio-venous malformation and associated cutaneous vascular lesion. He finally agreed for treatment after 5 years of progressive spastic right lower limb weakness leading to inability to mobilize. A two staged intravascular procedure was done followed by surgery with recovery of ASIA impairment scale grade B. 相似文献

Naturally occurring bithyniid snails, Bithynia siamensis goniomphalos (Prosobranchia: Bithyniidae), and their intermediate hosts were sampled from Khammouane Province, the Lao People's Democratic Republic, and the prevalence of the carcinogenic human liver fluke, Opisthorchis viverrini, was examined. The presence of O. viverrini cercariae in snails was examined by cercarial shedding test and then confirmed by specific hybridization probe-based real-time fluorescence resonance energy transfer (FRET) PCR method. The real-time FRET PCR method is based on a fluorescence melting curve analysis of a hybrid between an amplicon produced from the pOV-A6 specific sequence (Genbank accession no. S80278), a 162-bp repeated sequence specific to O. viverrini, and specific fluorophore-labeled probes. Mean melting temperature of O. viverrini DNA from the cercariae and each of two positive snails by shedding test was 66.3 ± 0.1. The O. viverrini infection rate in snails was 2.47% (2/81) by cercarial shedding test but was 8.52% (4/47) by real-time FRET PCR method. The real-time FRET PCR method is rapid and effective in examining a large number of snail samples simultaneously. Validation using molecular evidence from this procedure provides another tool for surveying the prevalence of O. viverrini-infected snails in Southeast Asian countries. 相似文献

Changes in personality and emotional status are common in individuals with multiple sclerosis (MS). The purpose of this study was to examine results based on the MMPI-2 before and following application of a statistical correction procedure (Gass, 1992). This was done to help determine changes in scale score elevations when items containing actual physical symptoms are identified and statistically removed. Twenty-eight participants with MS were administered the MMPI-2, then retested 1 year later. Stability of MMPI-2 scores over time was demonstrated. Results showed that when the correction procedure was applied to the MMPI-2, eight standard clinical scale scores dropped an average of 6.66 T-score points. Significant differences were obtained between standard MMPI-2 scored profiles and corrected profiles on Scales 1-3 and 8. Cautious interpretation of MMPI-2 results for neurological samples was indicated. This study extended prototypic research by using patients with MS, examining the stability of results over time (1 year), and introducing a more reliable method of deriving standard T-scores in the correction procedure. 相似文献
