Introduction: in March 2020, the first cases of SARS CoV-2 infection were registered in Uruguay and a health emergency was decreed. Objective: To describe the clinical and demographic characteristics of children under 15 years of age hospitalized with SARS-CoV-2 infection from March 13, 2020, to September 30, 2021, at Pereira Rossell Pediatric Hospital, a public reference center in Uruguay. Method: descriptive, retrospective study describing age, clinical manifestations, comorbidities, severity and treatment. Results: a total of 207 children were hospitalized, with a frequency of 1.6%. The median (interquartile range) age was 1.5 years (3 months - 8 years); <1 year accounted for 44%, and 54% were male. Comorbidities were present in 59 children. 71% of them were symptomatic, and among the symptomatic cases, 48% presented mild symptoms. Clinical manifestations were respiratory in 96 (65%) cases and non-respiratory in 51 (fever without a focus 15, gastrointestinal 19, viral exanthem 3, pediatric inflammatory multisystem syndrome 10, and atypical 3). Thirty patients were admitted to the Intensive Care Unit (ICU), and 3 required invasive ventilation. These patients had comorbidities, more days of fever, and required oxygen therapy compared to those who did not need ICU. One 2-year-old patient with comorbidities died. Conclusion: the hospitalization frequency was 1.6%. Most symptomatic children had mild forms of the disease. Among the symptomatic cases, respiratory manifestations were predominant. The findings from this series contribute to the understanding of the behavior of SARS-CoV-2 infection in children.

Fibrodysplasia ossificans progressiva in a 3-year-old female patient.

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant disease affecting connective tissue, primarily caused by de novo mutations of the ACVR1 gene. FOP is a disease with congenital malformations of the toes and heterotopic ossification in characteristic patterns that progresses with flare-ups and remissions. Cumulative damage results in disability and, eventually, death. This report aimed to describe a case of FOP to highlight the importance of early diagnosis of this rare condition. CASE REPORT: We describe the case of a 3-year-old female diagnosed with congenital hallux valgus, who initially presented with soft tissue tumors, predominantly in the neck and chest, with partial remission. Multiple diagnostic tests were performed, including biopsies and magnetic resonance imaging, with nonspecific results. We observed ossification of the biceps brachii muscle during evolution. The molecular genetic study found a heterozygous ACVR1 gene mutation that confirmed FOP. CONCLUSIONS: Knowledge of this rare disease by pediatricians is critical for an early diagnosis and for avoiding unnecessary invasive procedures that may promote disease progression. In case of clinical suspicion, performing an early molecular study is suggested to detect ACVR1 gene mutations. The treatment of FOP is symptomatic and focused on maintaining physical function and family support.

INTRODUCCIÓN: La fibrodisplasia osificante progresiva (FOP) es una enfermedad autosómica dominante rara que afecta el tejido conectivo, cuya causa principal son mutaciones de novo del gen ACVR1. Se trata de una enfermedad con malformaciones congénitas de los primeros ortejos y osificación heterotópica en patrones característicos que progresa en empujes y remisiones. El daño acumulativo provoca discapacidad y, eventualmente, la muerte. El objetivo de este trabajo fue describir un caso de FOP para favorecer el diagnóstico precoz de esta enfermedad infrecuente. CASO CLÍNICO: Se describe el caso de una paciente de 3 años, portadora de hallux valgus congénito, que inicialmente presentó tumoraciones dolorosas de tejidos blandos, de predominio en cuello y tórax, con remisión parcial de las mismas. Se realizaron múltiples pruebas diagnósticas, incluyendo biopsias e imágenes de resonancia magnética con resultados inespecíficos. En la evolución se observó osificación de músculo bíceps braquial. El estudio genético molecular encontró una mutación del gen ACVR1 en heterocigosis que confirmó el diagnóstico de FOP. CONCLUSIONES: El conocimiento de esta enfermedad por los pediatras es clave para realizar un diagnóstico precoz y evitar procedimientos invasivos innecesarios que pueden promover la progresión de la enfermedad. Ante la sospecha clínica, se sugiere realizar tempranamente el estudio molecular para detectar mutaciones del gen ACVR1. El tratamiento de la FOP es sintomático, centrado en el mantenimiento de la función física y el apoyo familiar.

[Epidemiological and clinical characteristics of children with COVID-19 cared for in a private health provider in Uruguay]. / Características epidemiológicas y clínicas de los niños con COVID-19 asistidos en un prestador de salud privado de Uruguay.

BACKGROUND: After the detection of the first cases of SARS-CoV-2 and the declaration of a health emergency in the country, community transmission of the virus remained low to moderate until November 2020, later becoming medium and high. Children under 15 years of age constitute the least affected group. The diagnosis is confirmed by RT-qPCR. The usefulness of the CT (cycle threshold) is discussed. AIM: To describe the epidemiological and clinical characteristics of children infected with SARS-CoV-2 and the relationship between the CT value and clinical presentation. METHOD: A descriptive, retrospective study was carried out in patients under 16 years of age with SARS-CoV-2 infection, assisted by a health provider in Montevideo between epidemiological week (EW) 3 of2020 and EW 9 of2021. Clinical variables, epidemiological notion, severity and evolution were described. The CT value at diagnosis was recorded and compared with the presence of symptoms. RESULTS: Patients under 16 years of age represented 16.6% of the total infected (794 in 4,792). 70% of the cases occurred between the months of January and February 2021. 67.6% presented intradomiciliary contact. The mean age was 7.5 ± 4.1 years, 51% were male. 55% presented symptoms and 45% were asymptomatic; no significant differences were observed in the mean, mode and age range of both groups. None presented comorbidities. In the group of 440 symptomatic patients, 55% presented fever: 32% associated with other symptoms, mainly upper respiratory symptoms, and 23% as the only symptom. The CT value was obtained in 536 of the 794 patients (67.5%). The mean CT was 29.7+5.8 in the symptomatic group vs. 31.5 ± 5.7 in asymptomatic patients (p > 0.05). Three patients were hospitalized, none required intensive care and none died. CONCLUSIONS: The prevalence and incidence of SARS-CoV-2 infection in children accompany that of adults and the majority had mild or asymptomatic forms, without complications. In this series, the CT value was not different in symptomatic and asymptomatic children. Close household contact was the main source of infection.

Características epidemiológicas y clínicas de los niños con COVID-19 asistidos en un prestador de salud privado de Uruguay / Epidemiological and clinical characteristics of children with COVID-19 cared for in a private health provider in Uruguay

INTRODUCCIÓN: Tras la detección de los primeros casos de SARS-CoV-2 y declararse la emergencia sanitaria en el país, la transmisión comunitaria del virus se mantuvo baja a moderada hasta noviembre de 2020 pasando luego a ser media y alta. Los niños bajo 15 años de edad constituyen el grupo menos afectado. El diagnóstico se confirma mediante RT-qPCR. La utilidad del CT (cycle threshold) es discutida. Objetivo: Describir las características epidemiológicas y clínicas de los niños infectados con SARS-CoV-2 y la relación entre el valor del CT y la presentación clínica. METODOLOGÍA: Se realizó un estudio descriptivo, retrospectivo, en pacientes bajo 16 años de edad con infección por SARS-CoV-2, asistidos en un prestador de salud de Montevideo entre la semana epidemiológica (S.E.) 3 del 2020 y la SE 9 del 2021. Se describieron variables clínicas, noción epidemiológica, gravedad y evolución. Se consignó el valor del CT al diagnóstico y se comparó con la presencia de síntomas. RESULTADOS: Los pacientes bajo 16 años representaron el 16,6% del total de infectados (794 en 4.792). El 70% de los casos ocurrió entre los meses de enero y febrero de 2021. El 67,6% presentó contacto intradomiciliario. La media de edad fue 7,5 ± 4,1 años, 51% de sexo masculino. Presentaron síntomas 55% y fueron asintomáticos 45%; no se observaron diferencias significativas en la media, moda y rango de edades de ambos grupos. Ninguno presentó comorbilidades. En el grupo de los 440 pacientes sintomáticos, 55% presentaron fiebre: 32% asociada con otros síntomas, principalmente respiratorios altos y 23% como único síntoma. El valor de CT se obtuvo en 536 de los 794 pacientes (67,5%). La media de CT fue 29,7 ± 5,8 en el grupo de sintomáticos vs. 31,5 ± 5,7 en asintomáticos (p > 0,05). Se hospitalizaron tres pacientes, ninguno requirió cuidados intensivos ni falleció. CONCLUSIONES: La prevalencia e incidencia de la infección por SARS-CoV-2 en niños acompañan a la de adultos y la mayoría cursó formas leves o asintomáticas, sin complicaciones. En esta serie, el valor de CT no fue diferente en niños sintomáticos y asintomáticos. El contacto estrecho intradomiciliario fue la principal fuente de infección.

Antibiotic susceptibility and fosfomycin resistance characterization in a cohort of children older than 6 years of age with urinary tract infection.

Fosfomycin tromethamol (FT) was reintroduced as an option for the treatment of low urinary tract infection (UTI) in children. In this study, we described the antibiotic sensitivity and mechanisms of resistance to fosfomycin in isolates from children older than 6 years with UTI. Urine culture and antibiotic susceptibility study were performed. In fosfomycin resistant strains, PCR for fos, blaCTX-M was performed followed by classification by phylogenetic group and sequencetyping. Escherichia coli was the most frequent etiological agent (89.2%). The susceptibility percentages were: fosfomycin 97.9%; amoxicillin-clavulanate 92.7%; cefuroxime and ceftriaxone 99%; nitrofurantoin 94.4%. An E. coli strain (ST69, phylogenetic group D) was resistant to fosfomycin (MIC 256mg/l) and carried the blaCTX-M-14 and fosA3 genes in a 45kb IncN-type plasmid. This is the first report of E. coli ST69 with blaCTX-M-14/fosA3 of human origin.

[Actinomyces sp. brain abscess: a rare infection in children. A case report]. / Absceso cerebral por Actinomyces sp.: una infección infrecuente en niños. A propósito de un caso.

Despite advances in diagnostic and treatment techniques, intracranial infections remain serious diseases with an estimated incidence of between 0.3 and 1.3 cases/100,000 inhabitants. We present a previously healthy patient with an intraoperative diagnostic of brain abscess, in whom although the culture showed polymicrobial development, Actinomyces sp was presumptively identified in the pathological anatomy. Given this finding, prolonged combined antibiotic therapy was performed with good evolution. Absceso cerebral por Actinomyces sp.: una infección infrecuente en niños. A propósito de un caso Actinomyces sp. brain abscess: a rare infection in children. A case report The presentation of this suppurative process was nonspecific and the contribution of the anatomopathology in the etiological diagnosis was relevant. The identification of an unusual microorganism defined the need to deepen the identification of predisposing factors.

A pesar de los avances en las técnicas de diagnóstico y tratamiento, las infecciones intracraneanas son aún enfermedades graves con una incidencia estimada entre 0,3 y 1,3 casos por cada 100 000 habitantes. Se presenta un paciente previamente sano con un absceso cerebral de diagnóstico intraoperatorio en quien, si bien el cultivo evidenció desarrollo polimicrobiano, se identificó presuntivamente Actinomyces sp. en la anatomía patológica. Dado este hallazgo, se realizó antibioticoterapia combinada prolongada con buena evolución. La presentación de este proceso supurado fue inespecífica y la contribución de la anatomía patológica en el diagnóstico etiológico fue relevante. La identificación de un microorganismo inhabitual definió la necesidad de profundizar en la determinación de factores predisponentes.

Primary meningococcal arthritis of the hip due to serogroup W in a pediatric patient.

BACKGROUND: Primary meningococcal arthritis (PMA) is defined as the presence of acute septic arthritis with the identification of Neisseria meningitidis in synovial fluid or blood cultures but no clinical evidence of sepsis or meningitis. This report aimed to describe a clinical case of PMA caused by serogroup W, an uncommon etiology of this disease in Uruguay, and review the available literature. CASE REPORT: We report the case of a 5-year-old female, with no past medical history, admitted to the emergency department with a 12-hour history of fever of 39 °C and a limp. The patient was hemodynamically stable and had no clinical evidence of meningitis. Hip ultrasound showed an increase in synovial fluid. Arthrocentesis showed purulent exudate and synovial fluid culture showed no growth after five days. The blood culture showed isolates of N. meningitidis, serogroup W. The patient received treatment with ceftriaxone, and drainage of the affected joint was performed with excellent clinical response. CONCLUSIONS: Primary meningococcal arthritis is a rare presentation of meningococcal disease. Systematic arthrocentesis and the adequacy of antibiotic therapy when septic arthritis is clinically suspected are essential for confirming the diagnosis and decompressive drainage of the involved joint. This report is the first of PMA caused by serogroup W in Uruguay. Although the most common serogroup involved in meningococcal arthritis is serogroup B in Uruguay, an increase in serogroup W-related diseases has been reported in Chile and Argentina, emphasizing the need for epidemiological surveillance.

[SARS-CoV-2 infection in children: Clinical characteristics and dynamics of SARS-CoV-2 transmission in a private health center. Uruguay]. / Infección por SARS-CoV-2 en niños: Características clínicas y dinámica de la transmisión de SARS-CoV-2 en un centro de salud privado. Uruguay.

BACKGROUND: To date, the prevalence and severity of the COVID-19 disease in children is lower than in adults. There are controversies regarding the dynamics of transmission and the role they play in the spread of the disease. AIM: To describe the clinical characteristics and transmission dynamics of patients under 15 years of age reported for suspicion and/or contact for COVID-19 in the period March 13 - November 20, 2020, in a private comprehensive health provider (Médica Uruguaya Medical Assistance Corporation, MUCAM). METHODS: Descriptive, retrospective study, in which clinical manifestations, epidemiological notion, secondary cases, severity and evolution are described. The risk and rate of secondary intradomiciliary attack were estimated. RESULTS: 539 patients met the inclusion criteria. The diagnosis was confirmed in 29 (5.3%): 13 (7.0%) of the 351 symptomatic children and 16 (4.5%) of the 188 asymptomatic. 100% of the confirmed cases and 85% of the unconfirmed cases had the notion of contact (p < 0.05). The OR for infection from an indoor contact was 26.5 (9.8-71.7) and the rate of secondary indoor attack 23% ± 4.1. CONCLUSIONS: In this series, mild and asymptomatic forms predominated in patients under 15 years of age. One in five exposed indoors contracted the disease, this notion of contact being decisive to indicate confirmatory studies. Most of the children did not continue the chain of transmission.

Children hospitalized for myiasis in a reference center in Uruguay.

BACKGROUND: Myiasis is an emerging disease caused by tissue invasion of dipteran larvae. In Uruguay, Cochliomyia hominivorax and Dermatobia hominis are the most frequent species. This study aimed to describe the epidemiological and clinical characteristics and the follow-up of children < 15 years hospitalized for myiasis in a reference center in Uruguay between 2010 and 2019. METHODS: We conducted a descriptive and retrospective study by reviewing medical records. We analyzed the following variables: age, sex, comorbidities, origin, the month at admission, clinical manifestations, other parasitoses, treatments, complications, and larva species identified. RESULTS: We found 63 hospitalized children: median age of 7 years (1 month-14 years), 68% of females. We detected risk comorbidities for myiasis (33%), of which chronic malnutrition was the most frequent (n = 6); 84% were from the south of the country; 76% were hospitalized during the summer. Superficial and multiple cutaneous involvements were found in 86%: of the scalp 50, furunculoid type 51, secondary to C. hominivorax 98.4%, and to D. hominis in 1.6%. As treatments, larval extraction was detected in all of them, surgical in 22%. Asphaltic products for parasites were applied in 94%, ether in 49. Antimicrobials were prescribed in 95%; cephradine and ivermectin were the most frequent. About 51% presented infectious complications, impetigo was found in 29, cellulitis in 2, and abscess in 1. CONCLUSIONS: Myiasis predominantly affected healthy schoolchildren during the summer months and was frequently associated with ectoparasites. Superficial infestation of the furuncle-like scalp by C. hominivorax was the most frequent form. Infectious complications motivated hospitalizations.

[Characterization of hypotonia-hyporesponsiveness after pentavalent vaccine and neurodevelopmental screening in children under 6 years of age, 2013-2018, Uruguay]. / Caracterización de la hipotonía-hiporrespuesta post vacuna pentavalente y tamizaje del neurodesarrollo en niños bajo 6 años de edad, 2013-2018, Uruguay.

BACKGROUND: Hypotonic-hyporesponsive episodes (HHE) is one frequently reported neurologic adverse effect supposedly attributable to vaccination and immunization. Its long-term impact on neurodevelopment is not completely known. AIM: To characterize the post-pentavalent vaccine HHE events reported to the Uruguayan Ministry of Health (M of H) between 2014 and 2018. To perform neurodevelopment screening of those who were under 6 years of age at the time of evaluation. METHODS: Descriptive study of the reports made to the National Farmacosurveillance System of the M of H. Neurodevelopment screening was performed using the National Guidelines for Developmental Surveillance. RESULTS: 30 cases were studied. Most cases occurred after the first doses, were of short duration and during the first hours after vaccination, with spontaneous recovery. Median time between the event and this evaluation was 2 years and 2 months. Screening tests were normal in 15. Delay in the language area was detected in one case. CONCLUSIONS: HHE events had similar characteristics to those described in the literature, with no severe short-term complications. Despite the limitations of the present study, no delays nor deviations were found in the development of the children who were evaluated.

Resumen: Introducción: la prescripción inadecuada de antibióticos (ATB) es un problema de salud pública. Objetivo: describir la frecuencia y los motivos de utilización inadecuada de ATB en niños hospitalizados en salas de cuidados moderados del Hospital Pediátrico, Centro Hospitalario Pereira Rossell, entre 15/6/2019 y 15/7/2019. Material y método: estudio descriptivo, transversal. Se incluyeron los menores de 15 años en tratamiento ATB sistémico independientemente del motivo de prescripción. Variables: edad, comorbilidades, diagnóstico al egreso, ATB (tipo, dosis, vía, intervalo, duración). El uso inadecuado se categorizó en: tipo A (selección de ATB inapropiado) y tipo B (ATB no indicado). Resultados: se incluyeron 100 niños, 53% sexo femenino, mediana edad 2,2 años (rango 0-14). Presentaban comorbilidades 52%. Se detectó prescripción inadecuada en 43%, categoría A 30% y categoría B 13% (p <0,05). La principal causa de prescripción inadecuada fueron las infecciones respiratorias (33%). Se observó predominio de prescripción adecuada en menores de 1 año e inadecuada en mayores de 5 años (p <0,05). En la categoría A (n=30) la causa más frecuente de prescripción inadecuada fue el uso de ATB de mayor espectro al requerido (14/30), seguido de la administración por vía intravenosa (5/30). Los ATB más frecuentemente prescriptos en forma inadecuada fueron ampicilina (17/43) y ceftriaxona (14/43). Conclusiones: la prescripción inadecuada de ATB en este centro es un problema frecuente. La indicación de ATB de mayor espectro al necesario por vía intravenosa en el tratamiento de infecciones respiratorias es el patrón predominante. Es necesario vigilar el cumplimiento de las recomendaciones nacionales.

Summary: Introduction: inappropriate prescription of antibiotics (ATB) is a public health problem. Objective: to describe the frequency and reasons for the inappropriate use of ATB in children hospitalized in the Moderate Care Ward of the Pereira Rossell's Pediatric Hospital Center between 06/15/2019 and 07/15/2019. Materials and Methods: descriptive, cross-sectional study. Children under 15 years of age were included in systemic ATB treatment regardless of the reason for the prescription. Variables: age, comorbidities, diagnosis at discharge, ATB (type, dose, route, interval, duration). Inappropriate use was categorized into: type A (selection of inappropriate ATB) and type B (ATB not indicated). Results: 100 children were included, 53% female, median age 2.2 years (range 0-14), 52% had comorbidities. Inappropriate prescription was detected in 43%, category A 30% and category B 13% (p <0.05). The main cause of inappropriate prescription was respiratory infections (33%). Prevalence of appropriate prescription was observed for the case of children under one year of age and inadequate in those over 5 years of age (p <0.05). In category A (n = 30), the most frequent cause of inadequate prescription was the use of ATB with a greater spectrum than required (14/30) followed by intravenous administration (5/30). The most frequently inappropriately prescribed ATBs were ampicillin (17/43) and ceftriaxone (14/43). Conclusions: the inappropriate prescription of ATB in this center is a frequent problem. The main pattern is the prescription of intravenous ATBs of a broader range than that required for respiratory infections. It is necessary to monitor compliance with national recommendations.

Resumo: Introdução: a prescrição inadequada de antibióticos (ATB) é um problema de saúde pública. Objetivo: descrever a frequência e os motivos do uso inadequado de ATB em crianças internadas em enfermarias de cuidados moderados do Hospital Pediátrico do Centro Hospitalar Pereira Rossell entre 15/06/2019 e 15/07/2019. Materiais e métodos: estudo descritivo, transversal. Incluíram-se menores de 15 anos de idade em tratamento sistêmico com ATB, independentemente do motivo da prescrição. Variáveis: idade, comorbidades, diagnóstico na alta, ATB (tipo, dose, via, intervalo, duração). O uso inadequado foi categorizado em: tipo A (seleção ATB inadequada) e tipo B (ATB não indicado). Resultados: incluíram-se 100 crianças, 53% do sexo feminino, meia-idade 2,2 anos (variação 0-14). 52% tinham comorbidades. Detectou-se prescrição inadequada em 43%, categoria A 30% e categoria B 13% (p <0,05). A principal causa de prescrição inadequada foi para o caso de infecções respiratórias (33%). Observou-se predomínio de prescrição adequada em menores de um ano e inadequada em maiores de 5 anos (p <0,05). Na categoria A (n = 30), a causa mais frequente de prescrição inadequada foi o uso de ATB com espectro superior ao necessário (14/30), seguido de administração intravenosa (5/30). Os ATBs mais frequentemente prescritos de forma inadequada foram ampicilina (17/43) e ceftriaxona (14/43). Conclusões: a prescrição inadequada de ATB neste centro é um problema frequente. A indicação de ATB com espectro maior que o necessário por via intravenosa no tratamento das infecções respiratórias é o padrão predominante. É necessário monitorar o cumprimento das recomendações nacionais.

Summary: Introduction: hemophilia is a hereditary disease, linked to chromosome X and caused by the deficit of factor VIII (type A) and IX (type B). Estimated prevalence at birth is 24.6 cases every 100,000 boys for hemophilia A and 5 cases every 100,000 cases for hemphilia B. The Transfusion Medical Department (TMD) of the Pereira Rossell Children's Hospital Center (CHPR, acronym in Spanish) is the national reference center (NRC) for patients under 18 years of age. A comprehensive, inter-disciplinary approach to hemophilic patients at a specialized center decreases morbidity and mortality and contributes to improving quality of life. Objective: to describe the epidemiologic, clinical and progression characteristics of hemophilic patients of under 18 years of age assisted at the TMD-CHPR between January 1st 2016 and December 31st, 2018. Methodology: descriptive, retrospective study of all hemophilic patients of under 18 years of age. Variables described: age, circumstances of diagnosis, type and severity of hemophilia, health check-ups, tests, complications, frequency and reasons for hospital admittance, treatment. The study protocol was approved by the Institutional Ethics Committee. Results: 67 patients were assisted, 57 with hemophilia A and 10 with hemophilia B. Median age was 8 years. Severe hemophilia was present in 61 patients, moderate in 2 and mild in 4. 41 had a family history of coagulopathy. Median age at diagnosis was 2 months. 24 patients with hemophilia A and 5 patients with hemophilia B were diagnosed during the neonatal period. 7 patients developed inhibitors, all of them with severe hemophilia. Conclusions: in this study there is a predominance of patients with severe hemophilia A, known family history of coagulopathy, under prophylactic treatment with coagulation factors. This study provides valuable information about the characteristics of these patients, which contributes to improved clinical management and planning strategies to improve their quality of care.

Malaria importada en niños: primer caso en Uruguay / Imported malaria in children: first case in Uruguay / Malária importada em crianças, o primeiro caso no Uruguai

Resumen: La malaria es un problema de salud a nivel mundial. Si bien en Uruguay existen ejemplares del género Anopheles, las especies descritas con mayor frecuencia no transmiten la enfermedad. Se comunica el primer caso de una niña con malaria importada, no complicada, por Plasmodium falciparum. El objetivo es sensibilizar al pediatra sobre una enfermedad reemergente y analizar su abordaje diagnóstico y terapéutico. Caso clínico: niña de 8 años, sana, procedente de Bolívar (Venezuela). Vive en Uruguay desde hace 15 días. Comienza cinco días previos al ingreso con fiebre de 41 °C, rinorrea y tos seca, vómitos ocasionales en las últimas 24 horas. Anorexia y marcado decaimiento. No lesiones de piel, cefalea, ni artromialgias. Examen físico: decaída, chucho febril, dolor abdominal difuso y hepatoesplenomegalia. Estudios complementarios: anemia, plaquetopenia, elevación de reactantes de fase aguda y de gamma glutamil transferasa. Ecografía abdominal: hepatoesplenomegalia moderada. Estudio parasitológico de sangre periférica: trofozoitos de Plasmodium falciparum, parasitemia menor a 10%. Se administra artemeter-lumefantrina durante tres días, seguido de primaquina por 14 días, con buena evolución. Conclusiones: la malaria debe ser considerada en un niño que proviene de zonas endémicas y se presenta con una enfermedad febril aguda, acompañada de chuchos, decaimiento y hepatoesplenomegalia. El estudio del frotis sanguíneo y gota gruesa realizado por el parasitólogo permitirá confirmar el diagnóstico y definir el abordaje terapéutico. Para disminuir la mortalidad es importante el diagnóstico oportuno y la identificación precoz de signos de malaria grave. El tratamiento será dirigido según la especie involucrada y riesgo de resistencia a los antimaláricos.

Summary: Malaria is a global health problem. Although there are specimens of the genus Anopheles, in Uruguay, the most frequently described species do not transmit the disease. We hereby report the first case of a girl with imported, uncomplicated Plasmodium falciparum malaria. The objective is to raise pediatricians' awareness regarding a re-emerging disease and analyze its diagnostic and therapeutic approach. Clinical case: 8-year-old, healthy girl from Bolívar (Venezuela) who had lived in Uruguay for 15 days. 5 days prior to admission started having 41°C fever, runny nose and dry cough and occasional vomit in the 24 hours prior to admittance. Anorexia and significant asthenia. No skin lesions, headaches or arthromyalgia. Physical exam: asthenia, feverish shivering, diffuse abdominal pain, and hepatosplenomegaly. Complementary studies: anemia, thrombocytopenia, high acute phase reactants and gamma glutamyl transferase. Abdominal ultrasound: moderate hepatosplenomegaly. Parasitological study of peripheral blood: Plasmodium falciparum trophozoites, parasitemia less than 10%. Artemether-lumefantrine was administered for 3 days, followed by primaquine for 14 days, with positive evolution. Conclusions: Malaria should be considered in cases of children from endemic areas who show acute febrile illness, accompanied by shivering, asthenia and hepatosplenomegaly. The study of the thick and peripheral blood smears carried out by the parasitologist will eventually confirm the diagnosis and define the therapeutic approach. In order to reduce mortality, it is essential to carry out a timely diagnosis and to identify symptoms of severe malaria early on. Treatment will depend on the species involved and risk of resistance to antimalarials.

Resumo: A malária é um problema de saúde global. Embora no Uruguai existam exemplares do gênero Anopheles, as espécies mais frequentemente descritas não transmitem a doença. Relatamos o primeiro caso de uma menina com malária importada não complicada por Plasmodium falciparum. O objetivo é sensibilizar o pediatra sobre uma doença reemergente e analisar sua abordagem diagnóstica e terapêutica. Caso clínico: menina saudável de 8 anos, procedente de Bolívar (Venezuela) que tinha morado no Uruguai por 15 dias. 5 dias antes da internação começa a ter febre de 41°C, rinorreia, tosse seca e vômitos ocasionais nas 24 horas anteriores à internação. Anorexia e astenia acentuada. Sem lesões cutâneas, dores de cabeça ou artromialgia. Exame físico: astenia, tremor febril, dor abdominal difusa e hepatoesplenomegalia. Estudos complementares: anemia, plaquetopenia, elevação dos reagentes de fase aguda e gama glutamil transferase. Ultrassonografia abdominal: hepatoesplenomegalia moderada. Estudo parasitológico do sangue periférico: trofozoítos por Plasmodium falciparum, parasitemia inferior a 10%. Administramos artemeter-lumefantrina por 3 dias, seguida de primaquina por 14 dias, com boa evolução. Conclusões: devemos considerar a malária em crianças procedentes de áreas endêmicas e com quadro febril agudo, acompanhado de tremores, astenia e hepatoesplenomegalia. O exame do esfregaço e de gota espessa quando feito pelo parasitologista vai confirmar o diagnóstico e definir a abordagem terapêutica. É importante realizar diagnóstico precoce e identificar os sinais de malária para diminuir o risco de mortalidade. O tratamento será administrado de acordo com a espécie envolvida e com o risco de resistência aos antimaláricos.

Características de las consultas de los recién nacidos en un servicio de emergencia pediátrica / Newborn consultations in a pediatric emergency department / Características das consultas de recém-nascidos em um serviço de emergência pediátrica

Resumen: Introducción: las consultas de recién nacidos (RN) a servicios de urgencia (SU) son cada vez más frecuentes. Sin embargo, no siempre corresponden a problemas con riesgo significativo. Objetivo: describir las características de las consultas de los RN en el SU de un prestador integral de salud privada entre el 1/1/2018 y el 31/12/2018. Metodología: estudio descriptivo, mediante revisión de historias clínicas y entrevista telefónica a las madres. Se analizaron variables del RN, de la consulta y maternas. Resultados: se registraron 237 consultas, correspondientes a 209 RN, sexo masculino 53%, media de edad 16 días. Los diagnósticos al egreso se agruparon en tres categorías: 1) consultas vinculadas a aspectos de puericultura 29%, 2) procesos fisiológicos 22% y 3) patologías agudas 49%. La tasa de hospitalización fue 27%. Ingresaron 64 RN: 2 del grupo 1 (escaso incremento ponderal); 6 del grupo 2 (ictericia); 56 del grupo 3. La media de la estadía hospitalaria fue 3 días (rango 1-14). No se registraron fallecimientos. Conclusiones: predominaron las consultas de RN sin patología aguda, potencialmente evitables. A pesar de ello, debido a la elevada vulnerabilidad de este grupo etario, el pediatra de urgencias debe realizar una evaluación minuciosa en estos niños. Es probable que, facilitando el acceso al primer nivel de atención y completando la información que se brinda a los padres, pueda disminuir la frecuencia de estas consultas. Conocer los problemas de salud de los RN y las principales preocupaciones de los padres constituye un importante insumo para implementar estrategias de mejora y optimizar la utilización de los recursos.

Abstract: Introduction: the number of newborn presentations to the Pediatric Emergency Department is gradually increasing. However, not all cases are caused by significant risks. Objective: to describe the characteristics of newborn presentations to the pedriatric emergency department of a comprehensive health care provider between January 1 and December 31, 2018. Method: descriptive study by analysing medical records and telephone interviews to mothers. Newborn, maternal and consultation variables were analysed. Results: 237 presentations were recorded, 209 of which corresponded to newborns, male neonates 53%, average age was 16 days. Diagnostics upon discharge were classified into three categories: 1) consultations associated to childcare (29%), 2) physiological processes (22%) and severe conditions (49%). Hospitalization rate was 27%. 64 newborns were hospitalized: 2 of them belonging to group 1 (low weight gain); 6 to group 2 (jaundice); 56 to group 3. Average hospital stay was 3 days (range 1-14). No deaths were recorded. Conclusions: most consultations were caused by non-severe conditions which were potentially avoidable. However, given the high vulnerability of this group of patients, emergency pediatricians must carefully assess these infants. It may be possible that the frequency of these consultations drops by making access to the first level of care easier, and by providing parents with more complete information. Learning about the health problems that are typical of newborns and the main concerns of parents constitutes an important input for the implementation of improvement strategies and to optimize the use of resources.

Resumo: Introdução: as consultas de recém-nascido (RN) são cada vez mais frequentes nos serviços de emergência (PS). No entanto, nem sempre correspondem a problemas com risco significativo. Objetivo: descrever as características das consultas de RNs no PS de uma instituição privada de saúde integral no período 1 de janeiro a 31 de dezembro de 2018. Metodologia: estudo descritivo, por meio de revisão de prontuários e entrevista telefônica com as mães. Analisaram-se RN, consulta e variáveis maternas. Resultados: foram registradas 237 consultas, correspondendo a 209 RNs, 53% do sexo masculino, média de idade de 16 dias. Os diagnósticos de alta foram agrupados em três categorias: 1) consultas relacionadas aos aspectos da puericultura 29%, 2) processos fisiológicos 22% e 3) patologias agudas 49%. A taxa de internação foi de 27%. Foram admitidos 64 RNs: 2 do grupo 1 (pequeno aumento de peso); 6 do grupo 2 (icterícia); 56 do grupo 3. O tempo médio de internação foi de 3 dias (variação 1-14). Não houve mortes. Conclusões: predominaram as consultas de recém-nascidos sem patologia aguda, potencialmente evitáveis. Apesar disso, devido à alta vulnerabilidade dessa faixa etária, o pediatra do pronto-socorro deve realizar uma avaliação criteriosa dessas crianças. É provável que, ao facilitar o acesso ao primeiro nível de atendimento e ao preencher as informações prestadas aos pais, seja possível diminuir a frequência dessas consultas. Conhecer os problemas de saúde dos recém-nascidos e as principais preocupações dos pais constitui um importante insumo para implementar estratégias de melhoria e otimizar o uso de recursos.
