We evaluated the potential for several North American mosquito species to transmit the newly introduced West Nile (WN) virus. Mosquitoes collected in the New York City metropolitan area during the recent WN virus outbreak, at the Assateague Island Wildlife Refuge, VA, or from established colonies were allowed to feed on chickens infected with WN virus(More)
BACKGROUND Transmission of dengue viruses (DENV), the leading cause of arboviral disease worldwide, is known to vary through time and space, likely owing to a combination of factors related to the human host, virus, mosquito vector, and environment. An improved understanding of variation in transmission patterns is fundamental to conducting surveillance and(More)
A knowledge, attitude, and practice (KAP) survey and an extensive entomologic survey were conducted in two sub-districts of Kamphaeng Phet province, Thailand, to test the hypothesis that correct dengue knowledge and practice reduce dengue vector populations. We found a negative association between respondents' knowledge of preventive measures and the number(More)
A hierarchical population genetic study was conducted among 19 Aedes aegypti populations in Thailand from Chiang Mai in the north to Songkhla province in the south. Single-strand conformation polymorphism analysis was used to examine variation in a 359-basepair region of the NADH dehydrogenase subunit 4 mitochondrial DNA gene (ND4). Seven haplotypes were(More)
Disruption and infection of median sternotomy wounds are grave complications often associated with prolonged hospitalization, high cost, and significant mortality. Effective prevention techniques are still debated. Successful management requires early recognition based on a high index of suspicion, detailed physical examination, appreciation of the clinical(More)
BACKGROUND The understanding of dengue virus (DENV) transmission dynamics and the clinical spectrum of infection are critical to informing surveillance and control measures. Geographic cluster studies can elucidate these features in greater detail than cohort studies alone. METHODS A 4-year longitudinal cohort and geographic cluster study was undertaken(More)
BACKGROUND Although conceptually sound, the use of multiple internal thoracic artery (ITA) bypass grafts to improve long-term clinical results remains controversial. This operation typically involves grafting the left ITA to the anterior descending artery and the right ITA to the right coronary artery. Past clinical studies of bilateral ITA operations have(More)
The bottle bioassay measuring the time-mortality rate is a simplified procedure for detecting insecticide resistance. It can be used with a biochemical microplate assay to identify the mechanism involved. This integrated approach was used to detect temephos resistance in Aedes aegypti from Nonthaburi (lowest use) and Roi Et (highest use). Ae. aegypti BKK1(More)
Cardiac contusions are being recognized with frequency. Among 507 patients with non-penetrating chest injuries, 210 had serial electrocardiograms sufficient to evaluate the heart. Forty-five of these 210 patients (21%) had cardiac contusions. These 45 patients and 3 others who were confirmed to have cardiac contusions at necropsy, comprise the 48 patients(More)
