[Fractional exhaled nitric oxide in monitoring and therapeutic management of asthma].

Introduction: Asthma is a chronic respiratory disease characterized by hyper-responsiveness and bronchial inflammation. The bronchial inflammation in these patients can be monitored by measuring the fractional exhaled nitric oxide. This study aims to determine fractional exhaled nitric oxide association with peak expiratory flow and with asthma control inferred by the Global Initiative for Asthma.

G2P[4] the most prevalent rotavirus genotype in 2007 winter season in an European non-vaccinated population.

Background: Recently, a high prevalence of G2P[4] rotavirus (RV) infection was reported from Brazil, and linked with the universal RV vaccination programme that used the G1P[8] live oral RV vaccine.

Objective: To determine the genotypes of RV co-circulating in a non-vaccinated population, in northern Portugal in the winter season of 2007.

Study Design: Prospective multicenter study of the genotypes circulating in the northwest region of Portugal during January to March 2007.
