RESUMO
OBJECTIVE: The objective of our study was to describe the efficacy of corticosteroids for ventricular tachycardia in four children with structurally normal hearts in whom endomyocardial biopsy revealed histologic changes of lymphocytic myocarditis. PATIENTS: The four patients had unexplained ventricular tachycardia. Three dysrhythmias were sustained, and one was inducible by exercise. Patient ages ranged from 4 months to 12 years. Three of the four patients had no symptoms. In two of them, ventricular tachycardia was identified by mass screening for heart disease. Two patients received oral steroids and two received pulse steroid therapy. RESULTS: In all four patients, significant underlying diseases were not found by noninvasive evaluation. Right ventricular endomyocardial biopsy revealed abnormal histologic findings of chronic lymphocytic myocarditis in all patients. Steroid therapy was effective in all four patients, two of whom received methylprednisolone pulse therapy. CONCLUSIONS: We conclude that unexplained ventricular tachycardia may be the only manifestation of clinically silent myocarditis. Steroid therapy should therefore be considered if conventional antiarrhythmic medication is not effective and histologic findings confirm the presence of lymphocytic myocarditis.

Thirteen asthmatic children were enrolled in a swimming program during five days. Pulmonary function test before and after swimming training was evaluated. Training did not change pulmonary function values, and asthmatic children improved swimming distance and enhanced swimming ability. No side effects were observed during study. After asthma can questionnaires indicated a high degree of enthusiasm and acceptance of the program by children and parents.

Se incluyeron 13 niños asmáticos en un programa de natación durante cinco dias. se realizaron pruebas de función pulmonar antes y despúes de la práctica de natación . Durante el entrenamiento nom se encontraron cambios en las pruebas de función pulmonar y los niños aumentaron la distancia nadada y su habilidad en la nataciòn. Se efectuaron efectos secundarios durante el estudio. Al final del campeonato de niños asmáticos una encuesta indicó gran entusiasmo y aceptación por parte de los niños y sus padres.
