Background: Little is known about the determinants of parental response when children appear to have a respiratory tract infection (RTI). Our objective was to identify what factors predict that parents will seek medical consultation.
Methods: In a prospective cohort study we consecutively recruited 400 children aged 2 months to 12 years from the urban, largely middle-class, primary-care practices of 7 pediatricians in Toronto.
Objective: To identify predictors of long duration of bronchodilator therapy in children with acute asthma.
Study Design: An emergency department prospective cohort study of 278 children > or =12 months of age, with clinical and socioeconomic parameters collected at baseline and 4 hours after administration of corticosteroids. Patients were classified into short and long therapy groups, with interval from first albuterol dose to initiation of administration every 4 hours < or =12 or >12 hours, respectively.
Background: Inhaled corticosteroids are effective in the treatment of children with asthma. It is uncertain how inhaled corticosteroids compare with oral corticosteroids in the management of severe acute disease.
Methods: We performed a double-blind, randomized trial involving 100 children five years of age or older who had severe acute asthma (indicated by a forced expiratory volume in one second [FEV1] that was less than 60 percent of the predicted value) and in whom the results could be evaluated.
