[Clinical significance of the most important abnormalities of respiratory organs].

The incidence rate and the clinical significance of inborn abnormalities of respiratory organs frequently are still underrated. In the clinic for paediatrics of the Medical Academy of Dresden malformations of respiratory organs, situated below the larynx, were demonstrated in 18 per cent of patients who had been referred hither in the course of 20 years for bronchopulmonary diagnostics. The clinical symptoms are very different and often uncharacteristic. Not seldom malformations of that kind first of all remain silent till a superinfection or a striking roentgenogram will arise the suspicion on a malformation. Following symptoms may refer to: permanent or intermitting stridor in the stenoses of the large respiratory tract (trachea and main bronchi), that is diagnosed as the most frequent anomaly. In nearly 80 per cent of the patients suffering from stenoses of a main bronchus symptoms of a recurrent or chronically obstructive bronchitis stood in the foreground. Mostly a tachy- and a dyspnoe are the leading symptoms in case of a connatal lobar emphysema, the most frequent anmaly of the pulmonary parenchyma followed by the pulmonary hypolasia and -agenesis. Chronic or relapsing pneumonias respectively a persisting cough may appear as symptoms in pulmonary sequestrations and in isolated anomalies of the bronchial aborization that otherwise in the majority of the cases will rest clinically mute. The long-term prognosis for children suffering from stenoses in the main bronchis is compared with those of tracheal stenoses relatively satisfactory.
