RESUMO

Introduction. During 2020 and 2021, the circulation of influenza virus remained below expectations worldwide. In Argentina, in 2022, we observed an uninterrupted circulation of influenza all year round. Our objectives were to describe the circulation patterns and clinical characteristics of hospitalized children with influenza. Population and methods. Retrospective, analytical, observational study. All children with influenza virus admitted to a children's hospital during the 2019-2022 period were included. Results. A total of 138 patients were admitted over 4 years; in 2019, the rate of hospital discharges was 4.5/1000, compared to 15.1/1000 in 2022. No cases were recorded in 2020 and 2021. In 2019, most cases were observed in the winter; in 79%, the cause was acute lower respiratory tract infection (ALRTI); influenza A was detected in 92%. In 2022, most cases occurred in the spring; 62% developed ALRTI; and influenza A was detected in 56%. Similar rates of vaccination and comorbidities were observed in both periods. Conclusions. In 2022, more hospitalizations due to influenza were recorded, which may have correlated with the use of more sensitive molecular diagnostic testing and a change in seasonality, with more cases observed in the spring. In 2019, influenza A predominated in lower respiratory tract infections, while in 2022, cases of influenza A and B were similar, with more extra-pulmonary forms.


Introducción. Durante 2020 y 2021, la circulación de los virus influenza se mantuvo por debajo de lo esperado en todo el mundo. En Argentina, en el año 2022 observamos una circulación ininterrumpida de influenza todo el año. Nuestros objetivos fueron describir los patrones de circulación y las características clínicas de niños internados con influenza. Población y métodos. Estudio retrospectivo, analítico, observacional. Se incluyeron todos los niños internados en un centro pediátrico con detección del virus influenza durante los años 2019-2022. Resultados. Se internaron 138 pacientes en 4 años; en 2019 se observó una tasa del 4,5/1000 egresos hospitalarios mientras que en 2022, fue del 15,1/1000. En 2020 y 2021 no hubo casos. En el 2019 la mayoría de los casos ocurrieron en invierno, la causa de la internación fue la infeccción respiratoria aguda baja (IRAB) en el 79 % y se detectó influenza A en el 92 % de los casos. En el 2022, la mayoría de los casos ocurrieron en primavera, el 62 % presentó IRAB y en el 56 % se detectó influenza A. Ambos períodos tuvieron similares frecuencias de vacunación y de comorbilidades. Conclusiones. En el 2022 se registraron más internaciones por influenza, lo que podría corresponder a que se realizaron métodos diagnósticos moleculares, que son más sensibles, y se observó un cambio en la estacionalidad con más casos en primavera. En 2019 predominó influenza A en infecciones del tracto respiratorio inferior, mientras que en el 2022 influenza A y B fueron similares, y hubo más formas extrapulmonares.

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.

RESUMO

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.

RESUMO

Introducción. La evidencia actual indica que la gravedad de la enfermedad por el coronavirus 2019 (COVID-19, por su sigla en inglés) es menor en la población pediátrica, los datos locales aún son limitados. Objetivo: caracterizar los aspectos clínicos y epidemiológicos de la infección por COVID-19 en menores de 18 años en Argentina. Población y métodos. Estudio transversal, observacional y analítico de casos confirmados de COVID-19 entre 0 y 18 años asistidos entre marzo de 2020 y marzo de 2021 en 19 centros pediátricos de referencia de Argentina. Se realizó un análisis multivariado para identificar las variables predictoras de cuadros graves. Resultados. Se incluyeron 2690 casos de COVID-19: 77,7 % residentes del área metropolitana de Buenos Aires, 50,1 % de sexo masculino, mediana de edad de 5,6 años. El 90 % ocurrió entre las semanas epidemiológicas 20-47 del 2020; 60,4 % con antecedente de contacto con personas con COVID-19; y 96,6 % en el entorno familiar. El 51,4 % presentó síntomas respiratorios; 61,6 % síntomas generales; 18,8 % síntomas gastrointestinales; 17,1 % síntomas neurológicos; 7,2 % otros y 21,5 % fueron asintomáticos. El 59,4 % fue hospitalizado; 7,4 fueron graves o críticos. Se registraron 57 casos de síndrome inflamatorio multisistémico. El antecedente de asma, displasia broncopulmonar, cardiopatía congénita, desnutrición moderada a grave, obesidad, enfermedad neurológica crónica y/o edad menor de 6 meses resultaron predictores independientes de gravedad. Residir en barrios vulnerables resultó protector. Conclusiones. Más de la mitad de los casos refirieron antecedente de contacto con personas con COVID-19 en el entorno familiar. La hospitalización no respondió a criterios clínicos de gravedad. La gravedad se encuentra asociada a la existencia de ciertas comorbilidades.


Introduction. The current evidence indicates that the severity of the coronavirus disease 2019 (COVID-19) is lower in the pediatric population but local data are still limited. Objective: To characterize the clinical and epidemiological aspects of COVID-19 infection in patients younger than 18 years in Argentina. Population and methods. Cross-sectional, observational, and analytical study of confirmed COVID-19 patients aged 0-18 years seen between March 2020 and March 2021 at 19 referral children's hospitals of Argentina. A multivariate analysis was done to identify predictors of severe cases. Results. A total of 2690 COVID-19 cases were included: 77.7% lived in the Metropolitan Area of Buenos Aires; 50.1% were males; patients' median age was 5.6 years. Of them, 90% were seen during epidemiological weeks 20-47 of 2020; 60.4% had a history of contact with COVID-19 patients; and 96.6% in their family setting. Also, 51.4% had respiratory symptoms; 61.6%, general symptoms; 18.8%, gastrointestinal symptoms; 17.1%, neurological symptoms; 7.2%, other symptoms; and 21.5% were asymptomatic. In addition, 59.4% of patients were hospitalized and 7.4% had a severe or critical course. A total of 57 patients developed multisystem inflammatory syndrome. A history of asthma, bronchopulmonary dysplasia, congenital heart disease, moderate to severe malnutrition, obesity, chronic neurological disease and/or age younger than 6 months were independent predictors of severity.Livinginavulnerableneighborhoodwas a protective factor.

RESUMO

INTRODUCCIÓN: La toxocariasis es una enfermedad parasitaria ampliamente distribuida. Las formas clínicas descritas son la asintomática (TA), larva migrans visceral (LMV), larva migrans ocular (LMO) y encubierta (TE). OBJETIVOS: Describir las características clínicas, de laboratorio, evolución y tratamiento de los casos y comparar las diversas formas clínicas de presentación. PACIENTES Y MÉTODOS: Análisis retrospectivo de todos los pacientes pediátricos con diagnóstico de toxocariasis atendidos en el Servicio de Infectología del Hospital General de Niños Pedro de Elizalde entre 2012 y 2019. RESULTADOS: Se incluyeron 85 pacientes. El 63,5 % fueron varones y la mediana de edad fue de 60 meses. Cuarenta y nueve pacientes presentaron TA, 14 LMV, 15 LMO y 7 TE. Los pacientes con LMV presentaron menor edad y recuento de eosinófilos más altos. Todos los casos de LMO presentaron mal pronóstico visual. Se indicó tratamiento con albendazol en todos los casos de LMV, en los casos activos de LMO, en 4 TE y en 3 TA. CONCLUSIÓN: Este estudio representa uno de los más grandes llevados a cabo en el país. Todas las formas clínicas excepto las LMO tuvieron buena evolución. Resulta fundamental enfatizar en la prevención y en el diagnóstico precoz de la enfermedad para instaurar de manera oportuna el tratamiento y evitar secuelas.


BACKGROUND: Toxocariasis is a widely spread parasitic disease. The most frequent clinical form is asymptomatic (AT) although it may present with visceral larva migrans (VLM), ocular larva migrans (OLM) or covert (TE) involvement. Aims: To describe the clinical presentation, laboratory, evolution and treatment characteristics of the cases and to compare the various clinical forms of presentation. PATIENTS AND METHODS: Retrospective analysis of all children diagnosed with toxocariasis attended at the Infectology Service of the Pedro de Elizalde Children's General Hospital between 2012-2019. RESULTS: We included 85 patients. 63.5% were males and the median age was 60 months. 49 patients presented AT, 14 VLM, 15 OLM and 7 TE. Children with LMV had lower age and higher eosinophil count. All the cases of OLM evolved with a poor visual prognosis. Treatment with albendazole was indicated in all cases of LMV, in active cases of LMO, in 4 TE and in 3 AT. CONCLUSION: This study represents one of the largest conducted in our country. The ocular forms had bad prognosis, while the visceral and covert forms had good evolution. It is essential to emphasize the prevention and early diagnosis of the disease in order to establish timely treatment and avoid sequelae.

RESUMO

BACKGROUND: Kawasaki disease (EK) is an acute systemic vasculitis with a risk of developing coronary aneurysms. AIM: To describe the clinical and epidemiological characteristics of children with EK in Argentina and to analyse the risk factors for the development of coronary's complications (CC). METHODS: Multicenter, retrospective, cross-sectional, observational and analytical study. It included patients younger than 18 years of age diagnosed with EK in hospitals in Argentina, between January the 1st, 2010 and December the 31th, 2013. RESULTS: N = 193 subjects. Age: medium: 29 months. Total incidence 5 cases / 10,000 hospital discharges. CC was observed in 15.5% of patients. Increased risk factors for CC: Elevated number of days with fever at the time of treatment placement (p = 0.0033); Increased of: heart frequency (p = 0.0021), erythrosedimentation (ESR) (p = 0.005), C-reactive protein (CRP) (p < 0.0001), leukocytes (p = 0.0006), neutrophils (p = 0.0021); Decreased of hematocrit (p = 0.0007) and hemoglobin (p < 0.0001).Association with CC: non-coronary cardiological alterations (OR = 10,818); PCR greater than 68 mg /L (OR = 11,596); leukocytes greater than 20,000 / mm3 (OR = 4.316); and ESR greater than 64 mm / 1 hour (OR = 4.267). CONCLUSION: The most frequent form of presentation was complete EK, the risk of CC was higher in males, younger than 5 years old, the risk factors (clinical and laboratory) were similar to those described in the literature.

Objetivos: Describir características clínico-epidemiológicas en niños con diagnóstico de EK en Argentina. Analizar factores de riesgo para el desarrollo de complicaciones coronarias (CC). Población y Métodos: Estudio multicéntrico, retrospectivo, transversal, observacional y analítico. Incluyó pacientes bajo 18 años de edad, con diagnóstico de EK en hospitales de Argentina, entre el 1 de enero de 2010 y el 31 de diciembre de 2013. Resultados: N = 193 sujetos. Edad: mediana: 29 meses. Tasa promedio total país 5 casos/10.000 egresos hospitalarios. Presentaron CC 15,5%. Mayor riesgo de CC: Mayor cantidad de días de fiebre al momento de colocación del tratamiento (p = 0,0033); Aumento de: frecuencia cardíaca (p = 0,0021), eritrosedimentación (VSG) (p = 0,005), proteína C reactiva (PCR) (p < 0,0001), leucocitosis (p = 0,0006), neutrofilia (p = 0,0021); Disminución de hematocrito (p = 0,0007) y hemoglobina (p < 0,0001). Asociación con CC: alteraciones cardiológicas no coronarias (ORv10.818); PCR mayor de 68 mg/L (OR = 11.596); leucocitos mayores a 20.000/mm3 (OR= 4.316); y VSG mayor de 64 mm/1° hora (OR = 4.267). Conclusión: La forma de presentación más frecuente fue EK completa, el riesgo de CC fue mayor en varones, menores de 5 años de edad, los factores de riesgo (clínicos y de laboratorio) fueron semejantes a los descritos en la bibliografía.

RESUMO

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.

RESUMO

INTRODUCTION: In 2012, PCV13 was introduced into the National Immunization Program in Argentina, 2+1 schedule for children <2 years. Coverage rates for 1st and 3rd doses were 69% and 41.0% in 2012, 98% and 86% in 2013; 99% and 89% in 2014, respectively. The aims of this study were to evaluate impact of PCV13 on Consolidated Pneumonia (CP) and Pneumococcal Pneumonia (PP) burden, and to describe epidemiological-clinical pattern of PP during the three-year period following vaccine introduction. METHODS: Hospital-based study at 10 pediatric surveillance units in Argentina. CP and PP discharge rates per 10,000 hospital discharges were compared between the pre-vaccination period 2007-2011 (preVp), the year of intervention (2012) and the post-vaccination period 2013-2014 (postVp). RESULTS: Significant reduction in CP and PP discharge rates was observed in patients <5 years [% reduction (95%CI)]: 10.2% (6.3; 14.0) in 2012 and 24.8% (21.3; 28.2) in postVp for CP discharge rate; 59.5% (48.0; 68.5) in 2012 and 68.8% (58.3; 76.6) in postVp for PP discharge rate. Significant changes were also observed in children ≥5 years, mainly in PP discharge rate. A total of 297 PP cases were studied; 59.3% male; 31.3% <2 years; 42.9% had received PCV13 in 2012 and 84.5% in posVp. Case fatality rate was 3.4%. PCV13 serotypes decreased from 83.0% (39/47) in 2012 to 64.2% (52/81) in postVp, p = 0.039. CONCLUSIONS: After PCV13 introduction, significant reduction in CP and PP discharge rates was observed in hospitalized children <5 years. In patients ≥5 years, PP discharge rate also decreased significantly.

Introduction. Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are prevalent both in Argentina and worldwide, and they may have a severe clinical course. Objectives: To estimate the hospitalization rate and case fatality risk factors of CA-MRSA infection. Methods. Cross-sectional, analytical study. All patients < 15 years old with community-acquired Staphylococcus aureus (CA-SA) infections admitted to 10 pediatric facilities between January 2012 and December 2014 were included. Results. Out of 1141 patients with CA-SA, 904 (79.2%) had CA-MRSA. The rate of hospitalization of CA-MRSA cases (per 10 000 discharges) among patients < 5 years old was 27.6 in 2012, 35.2 in 2013, and 42.7 in 2014 (p = 0.0002). The 2-4-year-old group was the most affected one: 32.2, 49.4, and 54.4, respectively (p = 0.0057). The clinical presentations included skin and soft tissue infections: 66.2%, pneumonia: 11.5%, sepsis/bacteremia: 8.5%, osteomyelitis: 5.5%, arthritis: 5.2%, psoas abscess: 1.0%, pericarditis/endocarditis: 0.8%, meningitis: 0.6%, and other: 0.7%. In terms of antibiotic resistance, 11.1% had resistance to erythromycin; 8.4%, to gentamicin; and 0.6%, to trimethoprim-sulfamethoxazole. All strains were susceptible to vancomycin. The case fatality rate was 2.2% and associated risk factors were (odds ratio --#91;95% confidence interval--#93;) age > 8 years (2.78, 1.05-7.37), pneumonia (6.37, 2.3717.09), meningitis (19.53, 2.40-127.87), and sepsis/bacteremia (39.65, 11.94-145.55). Conclusions. The rate of CA-MRSA infection was high; the rate of hospitalization increased in the 2013-2014 period; the 2-4-year-old group was the most affected one. A higher case fatality risk was observed among patients > 8 years old and those with the clinical presentations of pneumonia, meningitis, and sepsis.

RESUMO

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.

RESUMO

Introducción. Las infecciones invasivas por Streptococcus pyogenes (IISP) presentan elevada morbimortalidad aún en la actualidad; no obstante, a nivel regional, existen escasas publicaciones en pediatría. Objetivo. Describir la prevalencia, los factores predisponentes y las características clínicas de niños internados por IISP, analizar los factores de riesgo asociados a bacteriemia y letalidad. Material y métodos. Estudio retrospectivo, descriptivo de IISP en niños ≤ 18 años, internados en Pediatría de 20 centros asistenciales del país, entre 2010 y 2012. Variables evaluadas: edad, sexo, focos clínicos iniciales y tardíos, patología crónica previa, factores predisponentes, tratamiento y evolución. Resultados. Se analizaron 143 pacientes. Incidencia de 4,97 casos/10 000 egresos. Mediana de edad 54 meses; tenían patología crónica previa 11,2%. Tuvieron factores predisponentes 67,1%. Las formas de presentación más frecuentes fueron la piel y las partes blandas en 77, sepsis en 30, osteoarticulares en 19, fascitis necrotizante en 13, síndrome de shock tóxico en 11. Se aisló Streptococcus pyogenes en 56,6% de los hemocultivos; la presencia de más de un foco clínico y la ausencia de cirugía se asociaron a bacteriemia (OR 4,8; p= 0,003 y OR 3,1; p= 0,0012, respectivamente). El promedio de internación fue 13,4 días. La tasa de letalidad fue 7,6% asociada a síndrome de shock tóxico (OR 10; p= 0,005), fascitis necrotizante (OR 104; p < 0,0001) e ingreso a la Unidad de Cuidados Intensivos Pediátricos (OR 26; p < 0,001). Conclusiones. La mayoría de las IISP se presentaron en pacientes sin patología crónica previa. Los focos de presentación, frecuentemente con bacteriemia, fueron la piel y las partes blandas. Hubo asociación estadísticamente significativa entre bacteriemia y ≥ 2 focos iniciales y ausencia de cirugía. La letalidad, asociada a SSTS y fascitis necrotizante, fue similar a otras publicaciones.


Introduction. Invasive Streptococcus pyogenes infections (ISpIs) cause a high morbidity and mortality, even at present; however, at a regional level there are few publications on this subject in the field of pediatrics. Objective. To describe the prevalence, predisposing factors and clinical characteristics of children hospitalized for ISpI, and analyze risk factors associated with bacteremia and lethality. Material and methods. Retrospective, descriptive study on ISpIs in children <18 years old hospitalized in the Pediatric Ward of 20 healthcare facilities across Argentina between 2010 and 2012. Assessed outcome measures: age, gender, early and late clinical sources of infection, prior chronic condition, predisposing factors, treatment and evolution. Results. One hundred and forty-three patients were analyzed. The incidence of ISpI was 4.97 cases/10 000 hospital discharges. Patients' median age was 54 months old, and 11.2% had a prior chronic condition. Also, 67.1% had predisposing factors. The most common clinical manifestations were in the skin and soft tissue in 77 patients, sepsis in 30, bone and joint involvement in 19, necrotizing fasciitis in 13, and toxic shock syndrome in 11. Streptococcus pyogenes was isolated in the blood cultures of 56.6%. More than one clinical source of infection and no surgery were associated with bacteremia (odds ratio [OR]: 4.8, p= 0.003 and OR: 3.1, p= 0.0012, respectively). The average length of stay in the hospital was 13.4 days. Fatality rate was 7.6% in association with toxic shock syndrome (OR: 10, p= 0.005), necrotizing fasciitis (OR: 104, p < 0.0001) and admission to the Pediatric Intensive Care Unit (OR: 26, p < 0.001). Conclusions. Most ISpIs were observed in patients without a prior chronic condition. The most common manifestation was, frequently with bacteremia, in the skin and soft tissue. A statistically significant association was observed between bacteremia and ≥2 early sources of infection and no surgery. Fatality rate, in association with streptococcal toxic shock syndrome and necrotizing fasciitis, was similar to that observed in other publications.

RESUMO

Las infecciones de piel y partes blandas son una causa frecuente de consulta en los centros de atención primaria de la salud. Los datos de la epidemiología local de estas infecciones son escasos; el Staphylococcus aureus y el Streptococcus pyogenes son los principales agentes etiológicos. La emergencia, en los últimos años, de cepas de S. aureus meticilino resistentes provenientes de la comunidad y S. pyogenes resistentes a eritromicina plantea controversia en la elección del tratamiento empírico inicial. Este consenso nacional está dirigido a médicos pediatras, de familia, dermatólogos, infectólogos y otros profesionales de la salud. Trata el manejo clínico, especialmente el diagnóstico y tratamiento, de las infecciones de piel y partes blandas de origen bacteriano provenientes de la comunidad en pacientes inmunocompetentes menores de 19 años de edad.


Skin and soft tissue infections are a common reason for consultation in primary health care centers. Data from the local epidemiology of these infections are rare, but Staphylococcus aureus and Streptococcus pyogenes are known to be the major etiologic agents. The appearance in recent years of community-originated strains of methicillin-resistant S. aureus and erythromycin-resistant pyogenes raises controversy in the choice of initial empirical treatment. This national consensus is for pediatricians, dermatologists, infectologists and other health professionals. It is about clinical management, especially the diagnosis and treatment of community-originated skin and soft tissue infections in immunocompetent patients under the age of 19.
