Multicenter Study Comparative Study[Air pollution and recent symptoms of asthma, allergic rhinitis, and atopic eczema in schoolchildren aged between 6 and 7 years].
The objective of the study was to analyze the relationship between air pollutants and the prevalence of recent symptoms of asthma, allergic rhinitis, and atopic eczema in schoolchildren aged between 6 and 7 years. ⋯ Findings suggest that air pollutants such as SO2 and CO increase the risk of recent symptoms of asthma and allergic rhinitis in schoolchildren aged between 6 and 7 years in Spain.

Clinical Trial[Usefulness of radial endobronchial ultrasound-guided transbronchial needle aspiration for the diagnosis of mediastinal lymph nodes].
Transbronchial needle aspiration (TBNA) is a bronchoscopic technique that has been shown to be useful for sampling enlarged mediastinal lymph nodes. The yield of this technique can be increased by using endobronchial ultrasound (EBUS) to guide needle placement. The aim of the present study was to compare the yield of radial EBUS-guided TBNA to that of conventional TBNA in the analysis of mediastinal lymph nodes. ⋯ Radial EBUS guidance increases the diagnostic yield of TBNA in paratracheal and hilar lymph node stations.
