[Pneumococci isolated from vaccinated children with pneumonia]. / Pneumocoques isolés dans les pneumonies d'enfants vaccinés.

Among 76 children fully vaccinated with 7-valent conjugate vaccine and subsequently hospitalized from 2006 to 2009 for community-acquired pneumonia, isolated or with empyema or pleuritis, 10 had confirmed pneumococcal infections. All pneumococci isolated with blood or pleural culture were non vaccine serotypes (1, 5, 7F, and 19A). The proportion of pneumococcal pneumonias was similar to that in two series from the same hospital before the vaccine era. These data show that the 13-valent conjugate vaccine could be useful in prevention of community-acquired pneumonia and that bacteriologic survey of community-acquired pneumonia remains necessary.

[Epidemics of gastroenteritis caused by norovirus in Parisian children]. / Épidémies parisiennes de gastro-entérites à norovirus.

During the months of October and November 2006-2008, norovirus was detected in the stools of 14 children hospitalized with acute diarrhea (no sapovirus). Nine of these noroviruses belonged to a unique GGII4 strain, which produced severe clinical symptoms, present only in 2007 and 2008 and absent in 2006. This strain, identified in Europe mainly in the elderly, seems to be on the rise in children in the Paris area over the past few years.
