RESUMEN
La hidatidosis es una zoonosis con una amplia distribución en Argentina y en el mundo. Se adquiere en la infancia, pero se presenta, más frecuentemente, en la edad adulta. La población pediátrica representa el 10%-20% del total de los casos. Se presentan 47 niños con diagnóstico de hidatidosis durante un período de 20 años. La mediana de edad fue de 8 años (rango: 3-17) y, en su mayoría, tenían algún antecedente epidemiológico orientador, como la procedencia de un área endémica, rural y/o la tenencia de perros alimentados con visceras. El 85% fueron quistes únicos localizados en un solo parénquima. Las localizaciones quísticas pulmonares y hepáticas fueron las más frecuentemente encontradas. El tratamiento fue médico-quirúrgico en 45 pacientes (96%). Trece (28%) presentaron alguna complicación posterior, que fue más frecuente en aquellos con localización pulmonar. Tres (6%) recayeron entre el mes y los 24 meses, y requirieron una nueva cirugía. Ninguno falleció a causa de la enfermedad parasitaria.
Echinococcosis is a zoonotic disease that is widely spread across Argentina and worldwide. It is acquired during childhood but it is more common during adulthood. The pediatric population accounts for 10-20% of all cases. This study included 47 children diagnosed with echinococcosis over a 20-year period. Their median age was 8 years old (range: 3-17); most patients had some epidemiological history, such as having lived or living in an endemic or rural area and/or having dogs that are fed with viscera. Findings included 85% of single cysts in only one parenchyma. Cysts were most commonly located in the liver and lungs. Medical/surgical treatment was carried out in 45 patients (96%). Subsequent complications were observed in 13 patients (28%), which were more common in those with lung cysts. Three patients (6%) relapsed 1-24 months later and required a new surgery. No patient died as a result of the parasitic disease.

La varicela es una enfermedad muy contagiosa, cuya tasa de ataque alcanza el 90% en susceptibles. En comunidades cerradas, es fundamental implementar medidas de prevención ante brotes. Objetivos. Describir las características de los niños expuestos a casos de varicela en la CG, las medidas de profilaxis implementadas y su efectividad. Métodos. Estudio de cohorte prospectivo. Se evaluaron los niños expuestos a varicela en la CG entre 2008 y 2013, sus características demográficas, clínicas y vacunación y/o varicela previa, medidas de profilaxis y tasa de ataque secundaria. Resultados. N: 107. El 53% (n: 57) eran niñas. La mediana de edad fue 84 meses (RIC: 24144). El 95% (n: 102) teman enfermedad de base [oncohematológica: 39% (n: 42); neurológica: 18% (n: 19); cardiopatías congénitas: 9% (n: 10); y posoperatorios: 65 (n: 6)]. Tenían algún grado de inmunosupresión el 50% (n: 54). El 29% (n: 31) referían haber tenido varicela; el 27% (n: 29) referían no haber padecido la enfermedad; y el 41% (n: 44) no recordaban el antecedente. Solo 3% (n: 3) estaban vacunados. Sobre la base del estado inmunológico, edad y antecedentes de varicela previa, se indicó aciclovir como profilaxis en 61% (n: 65); vacuna, en 10% (n: 10); y gammaglobulina, en 1 paciente. No se observaron efectos adversos relacionados con las profilaxis. No se observó ningún caso secundario a los 30 días. Conclusiones. Las medidas implementadas resultaron efectivas en la prevención de casos secundarios. En niños sanos e inmunocomprometidos, la profilaxis con aciclovir fue efectiva y bien tolerada.
Introduction. Casa Garrahan (CG) accommodates children with complex conditions referred nationwide; these children are seen in children's hospitals located in the Autonomous City of Buenos Aires. Varicella is a highly-contagious disease, with attack rates of up to 90% among susceptible individuals. In closed communities, the implementation of outbreak control measures is critical. Objectives. To describe the characteristics of children exposed to varicella at CG, the implemented prophylaxis measures and their effectiveness. Methods. Prospective, cohort study. Children exposed to varicella at CG between2008 and 2013, their demographic and clinical characteristics, immunization and/or history of varicella, prophylaxis measures, and secondary attack rate were assessed. Results. N: 107. Fifty-three percent (n: 57) were girls. Their median age was 84 months old [interquartile range (IQR): 24-144]. Ninety-five percent (n: 102) had an underlying disease [hemato-oncological disease: 39% (n: 42); neurological disease: 18% (n: 19); congenital heart disease: 9% (n: 10); and post-operative period: 65 (n: 6)]. Fifty percent had some degree of immunosuppression (n: 54). Twenty-nine percent (n: 31) referred to have had varicella; 27% (n: 29) indicated that they never had the infection; and 41% (n: 44) did not recall a history of varicella. Only 3% (n: 3) had been vaccinated. Based on their immune status, age and history of varicella, acyclovir was indicated as prophylaxis in 61% (n: 65); immunization in 10% (n: 10); and gamma globulin in 1 patient. No adverse effects were observed in relation to the different prophylaxis measures. No secondary cases were observed at 30 days. Conclusions. Implemented measures were effective to prevent secondary cases. Among healthy and immunocompromised children, prophylaxis with acyclovir was effective and well-tolerated.

RESUMEN
Introducción. El uso inapropiado de antibióticos se relaciona con el incremento de los microorganismos resistentes, mayor morbimortalidad e impacto en la salud pública. Objetivo. Evaluar la efectividad de un programa para mejorar la adecuación del uso de los antimicrobianos en los pacientes internados en el Hospital Garrahan. Material y métodos. Estudio prospectivo, longitudinal, antes-después, sin grupo control. Período de estudio: del 1/7/2010 al30/6/2011. Se incluyeron pacientes con antibiótico parenteral. Se excluyeron los recién nacidos, quemados y aquellos con antibiótico como profilaxis. Se comparó el período previo y posterior a la implementación de talleres de discusión y monitoreo de indicaciones de antibióticos y la difusión de guías de tratamiento. Se realizó análisis univariado y estudio de regresión logística múltiple (STATA 8.0). Resultados. En el período preintervención, se incluyeron 376 pacientes; el 35,6% recibió tratamiento inadecuado. En el análisis de regresión múltiple, las variables finales de uso inadecuado fueron la infección respiratoria aguda baja (OR 3,80; IC 95% 1,35-3,26; p= 0,04), la fiebre sin foco en el paciente internado (OR 5,55; IC 95% 2,43-12,6; p < 0,01) y la neutropenia febril (OR 0,29; IC 95% 0,10-0,7; p < 0,01). Postintervención: se incluyeron 357 pacientes; 21,5% recibió tratamiento inapropiado. Se observó un descenso en la prescripción antibiótica inadecuada respecto al período preintervención (p < 0,01). En el análisis de regresión múltiple, las variables finales respecto al uso inadecuado fueron infección de piel y partes blandas (OR 0,33; IC 95% 0,13-0,93; p= 0,035) y neutropenia febril (OR 0,48; IC 95% 0,22-0,94; p= 0,04). Conclusión. El programa fue efectivo. Permitió mejorar las prácticas de prescripción de antibióticos en pacientes pediátricos hospitalizados.(AU)
Introduction. Inadequate antibiotic use is associated with an increased emergence of resistant microorganisms, higher morbidity and mortality rates, and an impact on public health. Objective. To assess the effectiveness of a program aimed at improving the use of antimicrobials in patients hospitalized at Hospital Garrahan. Material and Methods. Prospective, longitudinal, before and after study with no control group. Study period: From November 1st, 2010 to June 30th, 2011. Patients receiving parenteral antibiotics were included. Newborn infants, burned patients and those receiving prophylactic antibiotics were excluded. The periods before and after implementing discussion and monitoring workshops for antibiotic prescription and distributing treatment guidelines were compared. An univariate analysis and a multiple logistic regression study were performed (STATA 8.0). Results. In the pre-interventionperiod,376patients were included; of them, 35.6% had received inadequate treatment. The multiple regression analysis showed that the endpoints for inadequate antibiotic use were acute lower respiratory tract infection (OR: 3.80; 95% CI: 1.35-3.26; p=0.04), fever without a source in hospitalized patients (OR: 5.55; 95% CI: 2.43-12.6; p < 0.01), and febrile neutropenia (OR: 0.29; 95% CI: 0.10-0.7; p < 0.01). In the post-intervention period, 357 patients were included; 21.5% had received inadequate treatment. A reduction in inadequate antibiotic prescription was observed compared to the pre-intervention period (p < 0.01). The multiple regression analysis showed that endpoints for inadequate use were skin and soft tissue infections (OR: 0.33; 95% CI: 0.13-0.93; p = 0.035), and febrile neutropenia (OR: 0.48; 95% CI: 0.220.94; p= 0.04). Conclusion. The program was effective and allowed to improve antibiotic prescription practices in hospitalized children.(AU)
