Airway hyperresponsiveness in asthma. Not just a problem of smooth muscle relaxation with inspiration.

abstract：:We review recent advances in the use of corticosteroids (CS) in pediatric lung disease. CS are frequently used, systemically or by inhalation. Their mechanisms of action in pulmonary diseases are ill defined. CS exert direct inhibitory effects on many inflammatory cells through genomic mechanisms. There is a time lag ...
