ERS statement on tracheomalacia and bronchomalacia in children.

Tracheomalacia and tracheobronchomalacia may be primary abnormalities of the large airways or associated with a wide variety of congenital and acquired conditions. The evidence on diagnosis, classification and management is scant. There is no universally accepted classification of severity.

Bioelectrical impedance in young patients with cystic fibrosis: Validation of a specific equation and clinical relevance.

Background: Body composition (BC) analysis based on bioelectrical impedance analysis (BIA) provides conflicting results. The purpose of the study was to validate an equation specific for young patients with cystic fibrosis (CF), describe their BC and investigate its association with lung function.

Methods: Fifty-four young CF patients were evaluated by BIA and dual X-ray absorptiometry (DXA).
