Intratidal recruitment/derecruitment persists at low and moderate positive end-expiratory pressure in paediatric patients.

In paediatric patients positive end-expiratory pressure (PEEP) is traditionally set lower than in adults. We investigated whether moderately higher PEEP improves respiratory mechanics and regional ventilation. Therefore, 40 children were mechanically ventilated with PEEP 2 and 5cmHO.

Are we being drowned by overhydration advice on the Internet?

Objective: Because inappropriate recommendations about hydration during exercise appear widespread and potentially dangerous, we assessed the quality of a sampling of information currently available to the public on the Internet.

Methods: Internet searches using the Google search engine were conducted using the terms "hydration," "hydration guidelines," "drinking fluids" and "drinking guidelines" combined with "and exercise." From the first 50 websites for each search phrase, duplicates were removed yielding 141 unique websites that were categorized by source and examined for specific hydration related information and recommendations.

[Teaching emergency medicine at the University Medical Center Freiburg: establishment of an integrative concept].

Efforts to improve the quality of undergraduate medical education are commonly hampered by limited human and financial resources. This deficiency may be offset by the development of well structured and innovative teaching concepts, which optimize available assets. The newly conceived modular course "Emergency Medicine" at the University Medical Center Freiburg was conducted for the first time in the winter semester 2006/2007.

Distinct biological epochs in the reproductive life of female Drosophila melanogaster.

Mating alters the physiology and behavior of female Drosophila melanogaster resulting in a surge of egg laying, a decrease in receptivity to other males, and a decrease in life span. Here, we show striking differences in patterns of Drosophila egg laying and mortality rate dependent upon mating history. Our data reveal previously unreported epochs in the reproductive life of females: optimal, vulnerable and declining-terminal.
