Abstract Background Staphylococcus aureus long-term catheter-related bloodstream infection (LT-CRBI) are a frequent cause of morbidity and mortality. In LT-CRBI, it is recommended to remove the catheter. However, in pediatrics, management without catheter removal often necessary. Aims describe clinical characteristics outcome LT- CRBI, cmpare features according or retention Methods Retrospective cohort study. All patients with LT-CRBI from 1/1/2018 12/31/2022 pediatric hospital were...
Las infecciones invasoras por Streptococcus pyogenes (S. pyogenes) se asocian a una alta morbimortalidad. Se caracteriza la aparición de nuevos clones, que pueden asociarse determinados factores virulencia. En el año 2022 informó un aumento casos enfermedad invasora S. pyogenes. Objetivo: Describir las características clínicas, microbiológicas y moleculares en niños hospitalizados hospital pediátrico complejidad.Pacientes Método: Cohorte retrospectiva. incluyeron los pacientes con...
Campylobacter spp es una causa habitual de gastroenteritis en niños. La bacteriemia representa < 1% del total infecciones y ocurre pacientes inmunocomprometidos edades extremas. Objetivo: describir las características epidemiológicas, clínicas microbiológicas los niños con por spp. Pacientes Método: Estudio observacional retrospectivo que incluyó 0 a 16 años cursaron internación entre enero 2015 febrero 2022, infección bacteriémica al menos un hemocultivo aislamiento Se...

Macrolide-resistant Streptococcus pneumoniae emerged in Argentina 1995, representing 26% of invasive infection isolates children under 5 years old. The objectives this study were to describe the prevalence ermB and mefA genes macrolide-resistant S. from acute otitis media (AOM) determine their genetic relatedness. Between May 2009 August 2010, 126 324 otherwise healthy with a first episode AOM included. Twenty six these (20.6%) resistant erythromycin. Most frequent serotypes were: 14...
Background Antibiotic-resistant gram-negative bloodstream infections (BSI) remain a leading cause morbidity and mortality in pediatric patients with high impact on the public health system. Data resource-limited countries, including those Latin America Caribbean region, are scarce. The aim of study was to identify risk factors for acquiring carbapenem-resistant Enterobacteriaceae (CRE) bacteremia children assess use resources. Methods A retrospective case-control conducted analyze...
Introduction.Multidrug resistant Gramnegative (MDRGN) infections are an increasing problem in neonatal intensive care units.The objective of this study was to establish the epidemiological, clinical, microbiological, and evolutionary characteristics carbapenemresistant MDRGN risk factors for them at Division Neonatology a tertiary hospital.Population method.A retrospective cohort done patients with documented infection between 4/24/2013 4/29/2015.Results.Twenty-one were included.Their median...
The objective was to describe the epidemiological, clinical, microbiological, and evolutionary characteristics risk factors for mortality. Retrospective, cohort study. A total of 100 patients were included. Of these, 42 (42 %) had septic shock upon admission 56 (56 admitted intensive care unit. Bacteremia primary in 17 (17 %); catheter-related, 15 (15 secondary, 68 (68 %). most common source infection skin mucous membrane. Resistance one or more antibiotic groups 38 %. Thirty-one died (31...
Invasive Streptococcus pyogenes diseases represent the most severe form of infection produced by this microorganism. Early diagnosis and treatment are important, due to its potential severity. Etiological confirmation invasive is performed culture, which takes between 18 48 h. We tested a rapid immunochromatographic assay directly from clinical samples normally sterile sites positive blood culture bottles when cocci chains were observed Gram staining. Eighty analyzed. The test was in 35...
The introduction of the Haemophilus influenzae type b vaccine in immunization programs many countries has greatly reduced this invasive disease and carriage caused by serotype, also increasing other capsular types non-capsular isolations. There were 313 isolations H. under study, which recovered from a sterile site coming pediatric adult patients carrying disease. Patients treated at 90 different hospitals belonging to Red Nacional de Laboratorios para Meningitis e Infecciones Respiratorias...

Background: The emergence of strains Mycobacterium tuberculosis (Mt) that are resistant to antimycobacterial agents (DR-TB) is a worldwide problem which the magnitude has not been well described specially in pediatric patients. TB susceptibility surveillance and risk factors for DR-TB important issues consider at moment treatment. OBJECTIVE: To asses prevalence DR- children, identify clinical features, factors, outcome patients with DR-TB. Methods & Materials: Retrospective review all...
