Sisomicin, an aminoglycoside antibiotic, was used as sole bactericidal therapy in sixteen cases of severe bronchopulmonary infection for an average of 11,5 days (range 7 to 14) with a dose of 3,5 mg/kg per day in three intramuscular injections. Fifteen of these hospitalized patients presented with chronic airway obstruction which resulted in lowered O2 saturation (SaO2 congruent to 86,1%, range 74 to 93) and, in twelve patients, hypercapnia (PaCO2 = 55,7 torr, range 33--73). Two of these patients were under continuous assisted ventilation. Two patients had a lower lobe infiltrate and a lung abscess respectively. Proteus (n = 3), Pseudomonas (n = 9), K. pneumoniae (n = 2), E. Coli (n = 1), Enterobacter (n = 1), S. aureus (n = 1) and D. pneumoniae (n = 1) were the dominant organisms in the bronchial secretions isolated by Mulder's method; P. aeruginosa was associated with K. pneumoniae, P. rettgeri and E. coli respectively in three cases. In thirteen cases, either a clinical cure (n = 2) or a definite improvement was observed (sputum volume and purulence, auscultatory signs, temperature). However, among these patients were three cases of superinfection/colonization and two cases of persistent organisms. In addition, in two of the three cases showing no improvement colonization occured. The favorable results of this study appear to be due to vigorous antibiotic therapy combined with intensive adjunct therapy. No adverse local or systemic reactions clearly attributable to the drug were observed.

127 cases of tracheal dyskinesia were seen in infants and children out of which 87 were 1 to 12 months of age. The diagnosis was based on the existence of a collapse reducing the tracheal diameter of more than 50% on endoscopy. Endoscopic examination was performed without general anesthesia. This material represents 5,8% of the patients submitted to this procedure. 85 patients had "primitive" dyskinesia and 42 had major associated abnormalities. Uni or bilateral bronchial dyskinesia was associated in 43% of the cases. The four commonest presenting symptoms were a stridulous or wheezing respiration, recurrent bronchitis, chronic cough, cyanosis. The frequency of associated digestive troubles: gastroesophageal reflux aspiration was noteworthy. Several functional consequences were encountered: hypoxemia, hypercapnia, abnormalities of FRC, increased RL, lowering of dynamic compliance, alterations of perfusion and ventilation on scintiscans. The prognosis was good in primitive cases. Two deaths occurred, in the group with associated abnormalities. The pattern of the patient with primitive dyskinesia and that of the patient with dyskinesia and associated abnormalities are outlined. Some features remarkable in this series of patients are pointed out in a discussion of the pathophysiology of the syndrome. Increased transmural pressure is not a common cause of tracheal dyskinesia and infection as well. The possibility of a temporary intrinsic anomaly of the tracheal wall is suggested. Even if its exact mechanism remains unknown, tracheal dyskinesia is a distinct entity observed in infants and children. It appears as a common cause of recurrent bronchopulmonary disease in the young.
