[Validation of a clinical prediction tool to evaluate severity in children with wheezing].

Introduction: Acute lower respiratory infection in children usually causes Bronchial Obstructive Syndrome, which could include hipoxemia. Although pulse oximetry (SaO2) is the gold standard to evaluate hipoxemia, it is usually estimated from a clinical score not yet validated. We aimed to validate the respiratory distress score used in Argentina and to compare its performance with the one used in Chile.

[Seroprevalence of Mycoplasma pneumoniae in children aged under 12 years].

Introduction: Although Mycoplasma pneumoniae is usually assumed as an infection mainly prevalent in school aged children and adolescents, there is evidence supporting that it may occur at younger ages. This could be related to social conditions, like crowding and day care center/school attendance more frequently and at younger ages than two decades ago. We estimated the prevalence of antibodies anti- Mycoplasma pneumoniae in children aged under 12 years.
