Streptococcal Toxic Shock Syndrome Caused by a Streptococcus pyogenes emm22 Genotype with a CsrS Mutation: a Case Report.

A previously healthy 22-year-old woman was admitted to our hospital after an out-of-hospital cardiac arrest. Spontaneous circulation was restored prior to arrival at the hospital. However, the patient's vital signs remained unstable.

Structure and Diffusive Properties of Water in Polymer Hydrogels.

To investigate the diffusive properties of water in hydrogels, molecular orbital and molecular dynamics calculations of poly-,-dimethylacrylamide-water systems were performed. The results show that the mean diffusion coefficient of water drastically decreases in the middle dehydration stage. In this stage, the mobilities of water are restrained because part of the water forms hydrogen bonds to bind polymer chains due to a glass transition.

Two Cases of Intrafamilial Transmission of Community-Acquired Methicillin-Resistant Producing Both PVL and TSST-1 Causing Fatal Necrotizing Pneumonia and Sepsis.

Introduction: produces numerous toxins, such as toxic shock syndrome toxin 1 (TSST-1) and Panton-Valentine leukocidin (PVL). We isolated community-acquired methicillin-resistant (CA-MRSA) strains producing both TSST-1 and PVL isolated from severe necrotizing pneumonia cases in a Nepali family. Detection of these CA-MRSA strains is rare in the world, and infection with these strains can take a rapidly progressive and lethal course.
