Five children presented with recurrent respiratory illnesses and were noted to have pectus excavatum. In four patients subsequent investigation demonstrated a collapsible segment in the middle third of the left main bronchus, which appeared to lack cartilage support and caused gas trapping in the left lung. The remainder of the bronchial tree was normal. In the remaining child the clinical and physiologic pattern was very similar. In three children there were no other anomalities, but two had congenital heart disease. The association of bronchial anomalies and pectus excavatum may occur more often than suspected.

The long-term value of cromolyn sodium in the management of childhood asthma has been assessed over 3 to 5 years in 46 children with chronic perennial asthma who were not initially receiving corticosteroid therapy. The need to use steroids because of poor control during treatment with SCG was taken as a criterion of SCG treatment failure. Most such failures occurred early, but there were a few late treatment failures so that the proportion of SCG successes leveled of at 65% by the fourth and fifth years. Failure with SCG tended to occur in the younger children whose disease had progressed rapidly. By the fifth year, half of the children successfully treated by SCG had been able to discontinue use of the drug, and these children, but not the others, had diminished bronchial lability as shown on exercise testing.
