[Evaluation of systematic pulmonary function testing for asthma in children aged three to five years].

Unlabelled: Pulmonary function testing is not usually done in the preschool child, despite the recent data showing early deterioration in airway function in asthma.

Methods: We evaluated feasibility and clinical interest of flow-volume loop by forced expiratory maneuver and measure of airway resistance by interrupter technique (interrupter resistance), before and after inhalation of salbutamol, in 75 children aged three to five years seen in the ambulatory setting for asthma.

Results: Feasibility rate (92%) and reproducibility rate (91%) of those techniques were good, so that 84% of the cases could be exploited (63 children of 75).

[Indications and application of exercise tests in children].

Exercise tests are routinely used in children to assess cardio-respiratory and muscular adaptations to exercise. However these tests are of relatively recent use, and there is a lack of standardization and of relevant data in large groups in this population. The aim of this paper was to specify the common medical indications of exercise tests in children, to propose standardized protocols of these tests in some of the most common pathological situations as: exercise-induced asthma, chronic respiratory diseases (bronchopulmonary dysplasia, cystic fibrosis), muscular diseases.
