Safety, dose, immunogenicity, and transmissibility of an oral live attenuated Shigella flexneri 2a vaccine candidate (SC602) among healthy adults and school children in Matlab, Bangladesh.

In double-blind trials in Bangladesh, 88 adults, and 79 children (8-10 years) were randomized to receive either a single oral dose of 1 × 10(4), 1 × 10(5) or 1 × 10(6)CFU of SC602 (a live, attenuated Shigella flexneri 2a strain vaccine) or placebo. In the adult outpatient 1 × 10(6) CFU group, severe joint pain and body aches were reported by one and two vaccinees respectively. In the adult inpatient trial, SC602 was isolated from 3 volunteers, pre-vaccination antibody titers were high, and fourfold increases in serum IgG anti-LPS responses were observed in 2 of 5 subjects of the 1 × 10(6)CFU group.

Drug-eluting versus third-generation bare metal stents: the US strategy.

Drug-eluting stents have rapidly come to dominate the field of coronary intervention, constituting 85% of the US market just one year after introduction. The current utilization of bare metal stents in coronary intervention in the US is quite limited. This article will review technological advances in third-generation bare metal stents, which optimize procedural performance by means of improved flexibility, lower crossing profile, and thinner struts while maintaining fluoroscopic visibility and may portend a continued role for bare metal stents in some settings.

Venous thromboembolism among United States soldiers deployed to Southwest Asia.

Introduction: Military operations may represent a high-risk environment for venous thromboembolism (VTE). We sought to identify and describe cases of venous thromboembolism among US military personnel serving in Southwest Asia, and estimate relative disease rates compared to non-deployed personnel.

Materials And Methods: Retrospective review of imaging archives, hospital discharge codes, case logs and autopsy records for the diagnosis of deep vein thrombosis or pulmonary embolism occurring from 1 March 2003 through 29 February 2004 among U.

Meta-analysis of randomized clinical trials on the usefulness of acetylcysteine for prevention of contrast nephropathy.

Multiple small studies of oral N-acetylcysteine for prevention of contrast nephropathy have been performed, demonstrating variable efficacy. We performed a meta-analysis of the randomized clinical trials to clarify the degree of benefit.

Bacterial enteric pathogens in children with acute dysentery in Thailand: increasing importance of quinolone-resistant Campylobacter.

Current data on pathogen prevalence and drug resistance patterns are important for treatment and vaccine-development strategies. An etiologic study of acute bacterial dysentery was conducted in children up to 12 years of age in 2 major hospitals in and around Bangkok. Stool samples or rectal swabs and clinical data were collected.
