TAFFAREL, Pedro et al. Severe Staphylococcus aureus infection in three pediatric intensive care units: analysis of cases of necrotizing pneumonia. Arch. argent. pediatr. [online]. 2014, vol.112, n.2, pp.163-168. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2014.163.

Staphylococcus aureus frequently affects human beings. Among clinical manifestations, necrotizing pneumonia is associated with a high mortality rate. Our objective is to describe the progress of severe Staphylococcus aureus infections in three intensive care units and analyze cases ofnecrotizing pneumonia in the period ranging from January 2011 to March 2013. Forty-three patients were studied, 76.7% had a community-acquired infection, and 31 had community-acquired methicillin-resistant Staphylococcus aureus. The main reason for admission was respiratory failure. Bacteremia was confirmed in 55.8% of cases. Mechanical ventilation was required in 86% of admitted patients, while 27 patients developed septic shock. The length of stay in the intensive care unit was 13 (5-25) days, and the mortality rate was 14%. Necrotizing pneumonia was observed in 51% of cases. Conclusion. A high rate of community-acquired infection was identified. Necrotizing pneumonia was associated with a worse clinical course.
