Streptococcus pneumonia is the most common bacterial cause of community-acquired pneumonia in children. The reference standard for etiological diagnosis is isolation of S. pneumoniae from blood Since the advent of conjugate vaccines, disease caused by this organism can now be prevented. Many studies have been performed of the global incidence of invasive pneumococcal infections and of pneumococcal meningitis but few studies investigated bacteremic pneumococcal pneumonia and its complications in children. ⋯ The significant morbidity of bacteremic pneumococcal pneumonia and the implicated serogroups supports the use of the new heptavalent vaccine in the pediatric age group.

To analyze and compare the prognostic value of the pediatric index of mortality (PIM) score and lactate values on admission to a pediatric intensive care unit (PICU). ⋯ Both PIM score and blood lactate concentrations on admission to the PICU have a moderate prognostic value in critically-ill children. The prognostic value of the PIM score is greater than that of blood lactate concentration but is more difficult to obtain, whereas blood lactate determination is fast and easy.
