[Necrotizing fasciitis due to community-acquired panton-valentine leukocidin methicillin resistant Staphylococcus aureus]. / Fascitis necrosante por Staphylococcus aureus resistente a la meticilina adquirido en la comunidad productor de leucocidina de Panton-Valentine.

Community-Acquired Methicillin-Resistant Staphylococcus aureus (CA-MRSA) is a worldwide emerging pathogen that is able to produce serious skin and soft- tissue infections such as necrotizing fasciitis, as well as pneumonia and osteomyelitis. We present a 14 month child with necrotizing fasciitis, confirmed by magnetic resonance imaging, produced by CA-MRSA Panton-Valentine leukocidin producer. The clinical outcome was good after early surgical treatment and the administration of intravenous clindamycin for two weeks. We review microbiological aspects and treatment guidelines of these infections.

[Treatment of pneumococcal meningitis with dexamethasone]. / Dexametasona en el tratamiento de la meningitis neumocócica.

Our aim was two compare two different dexamethasone administration schedules in pneumococcal meningitis: short course (48h) and long course (96h) treatment. We diagnosed 18 pneumococcal meningitis treated with the two different schedules. We found a statistically significant longer duration of primary fever in patients who received dexamethasone for two days. We found no differences in the appearance of secondary fever, or in the development of severe neurological handicaps, or death between the two groups. We conclude that they are no significant differences between the two treatment schedules and that there is a need for developing early prognostic markers and adjuvant therapies that improve the outcome of patients with pneumococcal meningitis.
