[Recurrent toxin-mediated perineal erythema in an 11-year-old child].

Introduction: Recurrent perineal erythema is a rare toxin-mediated disease. We report the case of recurrent toxin-mediated perineal erythema in a child.

Case Report: An 11-year-old boy was hospitalized for erythematous pustular eruption involving the perineum and the axillary area.

Airway response to exercise by forced oscillations in asthmatic children.

Forced expiratory volume in 1 s (FEV1) detection of exercise-induced bronchoconstriction (EIB) to identify asthma has good specificity but rather low sensitivity. The aim was to test whether sensitivity may be improved by measuring respiratory resistance (Rrs) by the forced oscillation technique (FOT). Forty-seven asthmatic and 50 control children (5-12 y) were studied before and after running 6 min on a treadmill.

Post-exercise airway narrowing in healthy primary school children.

Changes in lung function after exercise in healthy primary school children have mostly been described in field studies. More complete description and insight into relevant mechanisms may be provided in lung function laboratory. The aim was to describe airway caliber and response to deep inhalation (DI) after exercise in healthy primary school children.
