A review of 25 infants developing pneumediastinum and subcutaneous emphysema was done. These observations suggested that increasing airways presure creates excessive alveolar distention. Pulmonary interstitial emphysema results from movement of air out of alveoli into interstitial areas. From this point air could dissect along the perivascular or interstitial spaces to the mediastinum.

Is an acute bronchial, obstructive disease of the infant caused mainly by the respiratory syncytial virus. It appears epidemically preceded by infections of the upper respiratory ducts, followed by coughing, dysnea, expiratory sibilants, suprasternal and subcostal during inspiration and radiologic evidences of choneking. In the differential diagnosis the physician must consider pulmonary dysgenesis, diaphragmatic hernia, congenital lobar emphysema, congenital cardiopathy, pneumothorax, obstruction due to foreign body, asthmatic crisis and fibrocystic disease. Fundamentally, two diagnoses should be discarded: 1) dyspenic bacterial bronchopneumonic syndrome; 2) prime infection T. B. bronchopneumonia with bronchiolitic syndrome.
