First, not every participant suffering SCH727965 clinical trial from TD provided a stool sample, hence we evaluated the proportions for each diarrheagenic E coli pathotype among collected stool samples rather than sick individuals to avoid assuming the proportions were the same. Second, during this cohort study we used direct stool PCR to differentiate
between E coli pathotypes rather than use different laboratory techniques for each different pathotype; we did so in order to avoid having data obtained from different techniques with different sensibilities and specificities among them. Third, more participants were enrolled during the summer months. This epidemiological finding could impact the recommended use of ETEC LT vaccines17 during warmer and cooler months. However, additional studies using ETEC LT vaccines would
need to be conducted in order to further evaluate the possible benefits during lower acquisition rate seasons. The difference between ETEC and EAEC rates in terms of seasonality suggests that the two important causes of TD have different pathways of transmission and reservoirs in Mexico. We are indebted to J.

“Background. Jeju Island is the most visited spot in South Korea; however, nearly it had the highest death rate in the country due to injury in 2008. We investigated injured patients who presented to an emergency department (ED) in Jeju and compared patients who were visitors with those who were residents of Jeju. Methods. A retrospective study was conducted
on injured patients visiting the ED at the Jeju National University Hospital from March 2008 to February 2010. The following factors were investigated: demographic data, new injury severity score (NISS), alcohol use, intention of injury, mechanism of injury, place of occurrence, activity when injured, patient outcome, and final mortality. Results. A total of 9,226 injured patients visited the ED during the study: 8,392 residents and 834 visitors (9.04%). The sex ratio and NISS were not different between the two groups. The mean age was younger in visitors (33.96 ± 23.37 vs 30.83 ± 18.79, p < 0.001). More intentional injuries and alcohol-related injuries occurred in residents than visitors (p < 0.001 and p < 0.005, respectively). In both groups, the most common reasons for injury were falling, stumbling, jumping, and being pushed. Visitors had more transportation-related injuries and were injured more often during leisure or play or when traveling.
