SARRION-SOS, Nerea et al. Adenitis-cellulitis syndrome, an infrequent form of presentation of the late-onset neonatal septicemia: Report of two cases. Arch. argent. pediatr. [online]. 2018, vol.116, n.6, pp.e769-e772. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2018.e769.

Septicemia is the main cause of neonatal mortality. The early-onset neonatal sepsis is usually related to maternal factor risks including recto-vaginal colonization. In the late-onset neonatal septicemia it is more difficult to establish the etiology because the majority of the cases are nosocomial or community related. The Streptococcus agalactiae (beta-hemolytic Streptococcus) is the most frequent germ associated with neonatal sepsis in developed countries. The late-onset form usually occurs with septic symptoms and meningitis and, in a few cases, with osteoarticular, skin and soft tissue infection. Adenitis-cellulitis syndrome is rarely seen, and its main cause is Staphylococcus aureus, followed by Streptococcus agalactiae. We report two cases of group B Streptococcus late-onset neonatal septicemia, both of them with adenitis-cellulitis syndrome. Patients recovered uneventfully after an adequate antibiotic therapy.
