RESUMO
El Haemophilus influenzae (Hi) causa enfermedad invasiva (EI). Se distinguen cepas capsuladas, como el serotipo b (Hib), y cepas no tipificables (HNT). Al año de declarada la pandemia por COVID-19, observamos un aumento de casos. Se describen las características clínico-epidemiológicas de niños con EI por Hi internados en el hospital (julio 2021-julio 2022). Hubo 14 casos; 12 previamente sanos. Aislamientos: Hib (n = 6), Hi serotipo a (n = 2), HNT (n = 5), 1 no se tipificó. Mediana de edad: 8,5 meses (RIC 4-21). Manifestaciones: meningitis (n = 5), neumonía (n = 6), celulitis (n = 2), artritis (n = 1). Nueve presentaron vacunación incompleta para Hib. Observamos un incremento de EI por Hi de 2,5 veces respecto a años previos. Estos datos sugieren el resurgimiento de Hib por la caída de las coberturas de vacunación y porque otras cepas de Hi no b están en aumento.
Haemophilus influenzae (Hi) causes invasive disease. There are encapsulated strains, such as serotype b (Hib), and non-typeable strains (NTHi). One year after the outbreak of the COVID-19 pandemic, the number of cases increased. In this report we describe the clinical and epidemiological characteristics of children hospitalized with invasive Hi disease (July 2021-July 2022). There were 14 cases; 12 were previously healthy children. Isolations: Hib (n = 6), Hi serotype a (n = 2), NTHi (n = 5); 1 case was not typified. Median age: 8.5 months (IQR: 421). Manifestations: meningitis (n = 5), pneumonia (n = 6), cellulitis (n = 2), arthritis (n = 1). Incomplete Hib immunization was observed in 9 children. Invasive Hi disease increased 2.5 times from previous years. These data suggest the reemergence of Hib due to a decline in vaccination coverage and an increase in other non-b-type Hi serotypes.

INTRODUCCIÓN: La meningitis bacteriana aguda (MBA) y la encefalitis son infecciones graves y el retraso en el tratamiento determina mayor morbimortalidad. En 2015 la FDA. aprobó un panel de RPC múltiple, BioFire® Filmarray® meningitis-encefalitis (FA-ME), que desde el 2019 se encuentra disponible en nuestro hospital. OBJETIVOS: Estimar número de determinaciones positivas mediante FA-ME, evaluar concordancia con cultivo convencional (CC) y describir si FA-ME permitió realizar cambios en el tratamiento. MATERIAL Y MÉTODOS: Estudio retrospectivo, descriptivo, realizado durante 2019-2021 en el Hospital de Niños Pedro Elizalde. Se revisaron reportes de niños con meningitis, encefalitis y meningoencefalitis y líquido-cefalorraquídeo patológico a quienes se les realizó FA-ME. RESULTADOS: Se incluyó a 32 niños, edad promedio: 48 meses. Fueron positivas 13 determinaciones de FA-ME: siete bacterias y seis virus. En dos MBA obtuvo desarrollo mediante CC. Con FA-ME se ajustó el tratamiento en dos MBA y se acortó el tratamiento intravenoso (IV). DISCUSIÓN: Nuestro trabajo permitió conocer la etiología de cinco MBA con cultivo negativo, de las cuales dos habían recibido antimicrobianos, administrar quimioprofilaxis a contactos epidemiológicos, acortar el tratamiento IV y suministrar menos dosis de aciclovir; en concordancia con la literatura médica. CONCLUSIONES: FA-ME permitió identificar la etiología en cinco MBA que no desarrollaron en CC, ajustar tratamientos empíricos inadecuados y acortar duración del tratamiento parenteral.
BACKGROUND: Bacterial meningitis and encephalitis are life-threatening infections, a delay in its treatment is associated with high mortality. In 2015, FDA approved the Multiplex PCR FilmArray™ meningitis/encephalitis syndromic panel (FA-MEP), and it is available in our hospital since 2019. AIM: To estimate the number of positive FA-MEP, to evaluate the correlation to conventional culture (CC) results and to describe if the FA-MEP technology allowed changes in the treatment. METHODS: Retrospective analysis of children with meningitis, encephalitis and meningoencephalitis and pathological cerebrospinal fluid analysis between 2019-2021, who were subject to FA-MEP testing at the Pedro Elizalde Children's Hospital. RESULTS: 32 children, mean age: 48 months. 11 patients had positive FA-ME tests: 7 bacterial, 6 viral. 2 patients correlated with CC. Based on the FAMEP results, treatment was adjusted in 2 bacterial meningitis and the duration of intravenous treatment was shortened. DISCUSSION: Our study allowed to establish the etiology of 5 culture negative bacterial meningitis, (2 had prior antibiotics), administer chemoprophylaxis to close contacts, and to administer fewer doses of acyclovir. CONCLUSIONS: The FA-MEP allowed us to identify 5 bacterial meningitis that tested negative by CC and early adjustment of inappropriate empirical antibiotics and to shorten the duration of parenteral treatments.

Shigella spp. is the most frequent micro-biological isolation in bacterial diarrhea in Argentina. It causes a watery diarrhea or dysenteric disease. It rarely causes extraintestinal problems. It has an incidence of bacteremia of 0,4-7,3%, and its appearance compels us to look for associated risk factors, as children under one year of age and immunodeficiency, among others. We describe two children with Shigella flexneri bacteremia. They presented with fever and diarrhea. One of them had primary immune deficiency.

Resumen Shigella spp. es el aislamiento microbiológico más frecuente en las diarreas bacterianas en Argentina. Clínicamente puede causar desde una diarrea acuosa hasta disentería. En forma infrecuente causa complicaciones extraintestinales, con una incidencia de bacteriemia desde 0,4 a 7,3%; asociado a factores de riesgo como niños menores de un año de edad e inmunodeficiencias, entre otros. Presentamos los casos clínicos de dos lactantes con bacteriemia por Shigella flexneri, que consultaron por fiebre y diarrea, uno de ellos con diagnóstico de inmunodeficiencia primaria.

Primary meningococcal arthritis is an extremely uncommon type of invasive meningococcal disease, with an incidence of 1.5- 1.8% of all paediatric cases of pyogenic arthritis. It is defined as the presence of acute septic arthritis without association with meningitis or the classic meningococcaemia, and isolation of Neisseria meningitidis in synovial fluid and/or blood culture. Typically monoarticular, mostly affects large joints. Prognosis is excellent with appropriated treatment. The aim of this study is to report 9 cases of primary meningococcal arthritis, evaluated at Hospital de Niños "Dr. R. Gutiérrez" in a period of 3 years, and to discuss clinical and epidemiologic issues.

La artritis meningocócica primaria es una forma rara de presentación de la enfermedad invasiva por meningococo. Se define como la presencia de artritis séptica aguda sin asociación con meningitis, ni clínica de meningococemia, y con aislamiento de Neisseria meningitidis en líquido articular o sangre. La incidencia comunicada en pediatría es del 1,5 -1,8 por ciento de lasartritis piógenas. Generalmente presenta compromiso monoarticular y de grandes articulaciones. La respuesta es excelente con tratamiento antibiótico adecuado. Nuestro objetivo es comunicar 9 casos de artritis meningocócica primaria registrados en el Hospital de Niños Dr. R. Gutiérrez, en un período de 3 años y discutir los aspectos clínicos y epidemiológicos.

A nasal septal abscess (NA) is defined as a collection of pus between the cartilage or bony septum and its normally applied mucoperichondrium or mucoperiostium. It is an uncommon disease which should be suspected in a patient with acute onset of nasal obstruction and recent history of nasal trauma, periodontal infection or an inflammatory process of the rhinosinusal region. We report a case of an 8-year-old boy with bilateral NA caused by community-acquired methicillin-resistant Staphylococcus aureus(MR-CO) in order to emphasize the importance of prompt diagnosis and adequate treatment to prevent the potentially dangerous spread of infection and the development of severe functional and cosmetic sequelae.

Se define como absceso del septum nasal (AN) a la colección de pus entre el cartílago o hueso del septum nasal y el mucopericondrioo mucoperiostio. Se trata de una patología poco frecuente que el pediatra debesospechar ante todo paciente que presente obstrucción nasal deinstalación aguda e historia reciente de traumatismo, infecciónperiodontal o proceso inflamatorio que involucre la regiónrinosinusal. Presentamos el caso de un paciente de 8 años con AN bilateral por Staphylococcus aureus meticilino-resistente de la comunidad (MR-CO), con el objeto de enfatizar la necesidad de un rápido diagnóstico y tratamiento para disminuir el riesgo de complicaciones infecciosas graves y posibles secuelas funcionalesy estéticas.
