Ultrasound and colour Doppler in infantile subglottic haemangioma.

Background: Subglottic haemangioma causes progressive and life-threatening stridor, typically manifesting at age 2-3 months. Standard diagnosis is by laryngoscopy. Larynx sonography is rarely used but allows assessment of the presence and extension of a mass that impinges on the subglottic airway.

Evaluation of clinical, radiologic, and laboratory prebronchoscopy findings in children with suspected foreign body aspiration.

Background: Foreign body aspiration (FBA) in infants and young children is a common and potentially life-threatening event. Although studies have extensively described the signs and symptoms of suspected FBA (sFBA), only few systematically compared their value for predicting bronchoscopy results.

Objectives: The objectives of this study were to describe the clinical and radiologic signs and symptoms of sFBA and to identify predictors of bronchoscopically proven FBA (pFBA).
