Lung function in asthmatic children after year or more without symptoms or treatment.

Lung function was examined in 24 children who for a year or more had not received treatment for asthma or had any asthmatic symptoms. Although clinical recovery from asthma was apparent, increased bronchial smooth-muscle tone remained present, which probably renders such children susceptible to obstructive lung disease in adult life. These children should be given guidance on treatment of their symptoms and instructed in preventive measures.
