Toxocariasis in migrant children: A 6 years' experience in a reference pediatric unit in Spain.

BACKGROUND: Toxocariasis is a worldwide distributed zoonosis that affects characteristically children. Clinical presentation is highly variable, often asymptomatic, and treatment duration is controversial. METHODS: A retrospective descriptive study (January 2014-December 2019) was performed in a referral Unit for Pediatric Tropical Diseases. Patients younger than 18 years of age diagnosed with toxocariasis were included. RESULTS: Out of 931 children screened for toxocariasis, 49 (5.3%) were seropositive. The median age was 11.0 years, 55.1% male and 30.6% referred contact with puppies. Overall, 34.7% were Latin-American, 24.5% Asiatic, 20.4% European, and 20.4% African. Only 34.7% presented symptoms, gastrointestinal the most common (52.9%). The 57.1% of children presented eosinophilia and 50% elevated total IgE. Most cases (95.9%) corresponded to covert toxocariasis. All children were treated with albendazole for 5, 14 or 21 days, and 4 children required a second course. Follow-up data were available in 32 children (65.3%) for a median of 7 months, showing a progressive decline in eosinophils, IgE-titers and ELISA optical density. CONCLUSION: Toxocariasis is mostly asymptomatic in children and eosinophilia is not always present. Serological tests should be included in migrant health screening and in the diagnostic assessment of eosinophilia. Eosinophil count, IgE-titers and ELISA optical-density could be useful during follow-up.

Imported malaria in children in Madrid, Spain, 2007-2013 / Malaria importada en niños en la Comunidad de Madrid, 2007-2013

Background: The majority of malaria cases diagnosed in Europe in the last few years have occurred in people living in non-endemic areas travelling back to their home country to visit friends and relatives (VFRs). Children account for 15-20% of imported malaria, with known higher risk of severe disease. Material and methods: A retrospective multicentre study was conducted in 24 hospitals in Madrid (Spain) including patients under 16 years diagnosed with malaria (2007-2013). Results: A total of 149 episodes in 147 children were reported. Plasmodium falciparum was the species most commonly isolated. Twenty-five patients developed severe malaria and there was one death related to malaria. VFR accounted for 45.8% of our children. Only 17 VFRs had received prophylaxis, and 4 of them taken appropriately. They presented more frequently with fever (98% vs. 69%), a longer time with fever (55 vs. 26%), delay in diagnosis of more than three days (62 vs. 37%), and more thrombocytopenia (65 vs. 33%) than non-VFRs, and with significant differences (p < 0.05). Conclusions: VFRs represent a large proportion of imported malaria cases in our study. They seldom took adequate prophylaxis, and delayed the visit to the physician, increasing the length of fever and subsequent delaying in diagnosis. Appropriate preventive measures, such as education and pre-travel advices should be taken in this population (AU)

Antecedentes: En los últimos años la mayoría de los casos de malaria en Europa se han producido en personas asentadas en zonas no endémicas que viajan a su país de origen para visitar a amigos y familiares (VFR). Los niños representan el 15-20% de la malaria importada, con el conocido alto riesgo de enfermedad grave. Material y métodos: Estudio multicéntrico retrospectivo en 24 hospitales en Madrid, que incluyó pacientes menores de 16 años con diagnóstico de malaria (2007-2013). Resultados: Se registraron 149 episodios en 147 niños. Plasmodium falciparum fue la especie más frecuentemente aislada. Veinticinco niños padecieron paludismo grave y hubo una muerte relacionada con la malaria. Los pacientes VFR representaron el 45,8% de nuestros niños estudiados. Solo 17 de los VFR habían recibido profilaxis y en solo 4 casos la tomaron apropiadamente. Estos pacientes presentaron con más frecuencia fiebre (98% vs 69%), retraso en el diagnóstico más de 3 días (62 vs 37%) y trombocitopenia (65 vs 33%). Conclusiones: Los niños VFR representaron una gran proporción de casos de paludismo importado en nuestro estudio. Rara vez tomaron la profilaxis de forma adecuada. Además estos niños presentaron un mayor retraso en la consulta al médico tras la aparición de síntomas, con el subsiguiente retraso en el diagnóstico. Es necesario tomar las medidas preventivas adecuadas, como la educación o el consejo pre-viaje, en esta población (AU)

Programa multicéntrico para la atención integral del recién nacido con agresión hipóxico-isquémica perinatal (ARAHIP) / Multicenter program for the integrated care of newborns with perinatal hypoxic-ischemic insult (ARAHIP)

INTRODUCCIÓN: El recién nacido con indicadores de potencial evento hipóxico-isquémico perinatal precisa de una atención integral que detecte precozmente si necesita tratamiento con hipotermia y el control de los factores agravantes del da˜no cerebral en las primeras 6 h de vida. PACIENTES Y MÉTODOS: Aplicación de un programa prospectivo de ámbito poblacional que ordena y sistematiza la atención durante las primeras 6 h de vida en los ≥ 35 semanas nacidos con indicadores de agresión hipóxico-isquémica perinatal. El programa involucra 12 hospitales (91.217 m2), 7 de nivel asistencial i-ii y 5 de nivel III. Se establecen 4 protocolos: a) detección del recién nacido con potencial agresión hipóxico-isquémica; b) vigilancia de la repercusión neurológica y en otros órganos; c) control y tratamiento de complicaciones, y d) vigilancia y acciones durante el transporte. RESULTADOS: Entre junio del 2011 y junio del 2013, de 32.325 recién nacidos ≥ 35 semanas, 213 cumplieron criterios de potencial agresión hipóxico-isquémica perinatal (7,4 por 1.000). El 92% siguió la monitorización establecida en el programa; 33 recién nacidos tuvieron encefalopatía hipóxico-isquémica moderada-grave (1 por 1.000) y 31/33 (94%) recibieron tratamiento con hipotermia. CONCLUSIONES: El programa Atención integral al Recién nacido con Agresión Hipóxico-Isquémica Perinatal ha permitido ofrecer atención integral al recién nacido con indicadores de agresión hipóxico-isquémica perinatal. Se han controlado factores comórbidos agravantes de la lesión cerebral y se han detectado aquellos con encefalopatía hipóxico-isquémica moderadagrave, permitiendo iniciar la hipotermia dentro de las primeras 6 h de vida. Programas de ámbito poblacional son cruciales para disminuir la morbimortalidad asociada a la encefalopatía hipóxico-isquémica

INTRODUCTION: Newborns with perinatal indicators of a potential hypoxic-ischemic event require an integrated care in order to control the aggravating factors of brain damage, and the early identification of candidates for hypothermia treatment. PATIENTS AND METHODS: The application of a prospective, populational program that organizes and systematizes medical care during the first 6 hours of life to all newborns over 35 weeks gestational age born with indicators of a perinatal hypoxic-ischemic insult. The program includes 12 hospitals (91,217 m2); two level I centers, five level II centers, and five level III hospitals. The program establishes four protocols: a) detection of the newborn with a potential hypoxic-ischemic insult, b) surveillance of the neurological repercussions and other organ involvement, c) control and treatment of complications, d) procedures and monitoring during transport. RESULTS: From June 2011 to June 2013, 213 of 32325 newborns above 35 weeks gestational age met the criteria of a potential hypoxic-ischemic insult (7.4/1000), with 92% of them being cared for following the program specifications. Moderate-severe hypoxic-ischemic encephalopathy was diagnosed in 33 cases (1/1,000), and 31 out of the 33 received treatment with hypothermia (94%). CONCLUSIONS: The program for the Integrated Care of Newborns with Perinatal Hypoxic-Ischemic Insult has led to providing a comprehensive care to the newborns with a suspected perinatal hypoxic-ischemic insult. Aggravators of brain damage have been controlled, and cases of moderate-severe hypoxic-ischemic encephalopathy have been detected, allowing the start of hypothermia treatment within the first six hours of life. Populational programs are fundamental to reducing the mortality and morbidity of hypoxic-ischemic encephalopathy

Interpretación de la prueba de tuberculina en niños con alteración de la inmunidad celular mediada por linfocitos CD4 / Interpretation of the tuberculin test in children with CD4 lymphocyte cell mediated immunity changes

La inmunosupresión puede ser causa de un falso negativo en la interpretación de la prueba de tuberculina (PT). Se realiza un estudio transversal en una población de niños adoptados e inmigrantes para analizar si la alteración de la inmunidad celular mediada por linfocitos CD4 puede modificar el resultado de la PT. Se incluyó a 1.074 niños (enero de 2003-diciembre de 2008). El estudio de subpoblaciones linfocitarias se efectuó en 884 niños. Un 5,3% tuvo valores de linfocitos CD4 < 25%. No existieron diferencias en el resultado de la PT entre niños con valores normales y patológicos de linfocitos CD4. Varios estudios, incluyendo nuestra serie, han demostrado que no existe una correlación directa entre el valor porcentual de linfocitos CD4 y el resultado de la PT. No obstante, estos resultados deberían confirmarse con series más numerosas y con un mayor porcentaje de niños con valores porcentuales de linfocitos CD4 < 25%

Immunosuppression could be a cause of a false negative tuberculin skin test (TST) result. A cross-sectional study was performed on a population of immigrants and internationally adopted children to analyse whether CD4 cell counts could modify the TST results. A total of 1074 children were included between January 2003 and December 2008. CD4 cell counts were performed on 884 children, in whom 5.3% had CD4 values <25%. There were no differences in TST results among children with normal and pathological CD4 cell counts. Several studies, including this one, have shown that there is no direct association between the CD4 value and the TST results. These results should be confirmed with larger series and with a higher percentage of children with CD4 values <25%

Actualización en el diagnóstico y tratamiento de la malaria / Update in the diagnosis and treatment of malaria

En los últimos años estamos asistiendo a un aumento de la inmigración, de los niños viajeros y de adopción internacional, lo cual ha favorecido el resurgimiento de la malaria. Dado que la mortalidad asociada no es despreciable, resultan esenciales tanto el diagnóstico como el tratamiento precoz. Por otra parte, se han producido cambios terapéuticos importantes (nuevos fármacos, desarrollo de resistencias…). En este artículo se realiza una puesta al día y se recogen las nuevas recomendaciones siguiendo las directrices de las principales guías disponibles (OMS, CDC)(AU)

An increase in the cases of malaria in our country has been observed due to immigration, and adopted children. Malaria management requires an integrate approach, including prompt diagnoses and treatment to avoid the associated morbidity and mortality. In the last years, new recommendations have been introduced due to the appearance of new resistant areas. In this article we aim to provide a summary of the key recommendations following the main malaria guidelines (WHO and CDC)(AU)

Experiencia en el diagnóstico de hepatitis E en una unidad de enfermedades infecciosas tropicales / Experience in the diagnosis of hepatitis e in a tropical infectious diseases unit

El virus de la hepatitis E (VHE) es endémico en algunos países en vías de desarrollo. Produce cuadros de hepatitis aguda con casos esporádicos o epidemias. La principal vía de transmisión es fecal-oral sobre todo por aguas contaminadas. En países desarrollados cada vez se describen más casos debido fundamentalmente a los movimientos poblacionales (viajeros, inmigrantes, adopciones internacionales) aunque también han aumentado los casos autóctonos. Actualmente disponemos de técnicas serológicas y moleculares para el diagnóstico de la infección. Describimos la experiencia diagnóstica de la infección por VHE en una Unidad de Patología Infecciosa y Tropical Pediátrica de Madrid(AU)

The hepatitis E virus (HEV) is endemic in some developing countries. It produces acute hepatitis in sporadic cases or epidemics. The main transmission route is faecal-oral by contaminated waters. In developed countries the cases described are more and more frequent, mainly due to population movement (travellers, immigrants, international adoptions), although there have also been increases in the local population. We currently have serological and molecular techniques for the diagnosis of this infection. We describe the experience in the diagnosis of the infection by HEV in a Paediatric Tropical Infectious Diseases Unit in Madrid(AU)
