[Viral respiratory tract infections in the first six months of life]. / Infecciones virales de vías respiratorias en los primeros seis meses de vida.

BACKGROUND: Respiratory syncytial virus and Influenza virus infections are known causes of hospital admission in infants. It is less well known the pattern of virus infections in infants under 6 months of age in the outpatient setting. OBJECTIVE: To describe the clinical and epidemiological pattern of community-acquired viral respiratory infections in infants under 6 months. PATIENTS AND METHODS: A cohort of infants from the 8 and 9 Madrid Health Districts was followed by telephone calls every two weeks since birth during the epidemic winter season. Clinical and epidemiological data were collected in pre-designed questionnaires. Nasopharyngeal aspirate was obtained in every patient with symptoms compatible with respiratory infection. Diagnosis of the more common virus was made with direct immunofluorescence and nucleic acid amplification test (PCR). RESULTS: Were recruited 316 newborns. The 1,865 phone calls made (median 4 for every child), produced 106 visits, and the illness confirmed in 89 illness. Rhinitis (91%) and cough (69%) were the most common symptoms. Upper respiratory infection was the principal clinical diagnosis (84.5%), and 17 of the 72 samples (23.2%) were positive. Most common viruses were RSV (41.1%) and rhinovirus (35.2%). Of the children visited, 17 out of 106 (16%) (5.3% of the cohort) were admitted to hospital. Diagnoses were febrile syndrome and bronchiolitis. We did not find any epidemiological factor associated with viral respiratory infection in positive cases. CONCLUSIONS: In our population most of the respiratory infections in infants are minor and do not need hospital assistance. Rhinovirus and RSV are the major pathogens. We did not find any epidemiological factor associated with viral respiratory infection.

[Treatment of Tourette syndrome and its comorbidity: experience with 17 cases]. / Tratamiento del síndrome de Tourette y su comorbilidad: presentación de 17 casos.

INTRODUCTION: Clinical characteristics and comorbid disorders of Tourette syndrome (TS) are reviewed along with a presentation of our experience with 17 cases. MATERIAL AND METHODS: We carried out a retrospective study of pediatric patients with TS admitted from 1998 to 2004 in Fundación Hospital Alcorcón. RESULTS: Seventeen patients were obtained, 16 of whom were men and there was only 1 woman. Present age ranged from 7 to 17 years old. Most frequent comorbid disorders were attention deficit disorder (ADD) in 9 patients, (53%), obsessive-compulsive disorder in 8 (48%) and anxiety in 7 (41%). Learning disorders were found in 7 patients (41%), 5 of whom have concurrent ADD and 1 severe obsessive compulsive disorder. Psychopharmacological treatment was withdrew in the 2 cases treated with halloperidol due to the presence of severe extrapyramidal symptoms (EPS) and in 3 of the 7 cases treated with pimozide (one of them was withdrawn due to EPS). No EPS was found with atypical neuroleptics, but sedation and weight gain was common. Methylphenidate was administered to 7 patients without an increase in tics. CONCLUSIONS: In our sample the most common comorbid disorders were ADD, obsessive-compulsive disorders, anxiety and learning disorders. Atypical neuroleptics were better tolerated than classic ones, although the incidence of side effects is elevated. Methylphenidate was not associated with tic worsening.

Infecciones virales de vías respiratorias en los primeros seis meses de vida / Viral respiratory tract infections in the first six months of life

Antecedentes: El virus respiratorio sincitial (VRS) y otros virus son causas conocidas de hospitalización en lactantes. Menos conocido es el patrón de virus en infecciones extrahospitalarias en menores de 6 meses. Objetivo: El objetivo de este estudio es describir las características clínicas y los factores epidemiológicos asociados con las infecciones respiratorias virales de ámbito extrahospitalario en menores de 6 meses. Pacientes y métodos: Estudio prospectivo en cohorte de niños de las áreas 8 y 9 de Madrid controlados desde el nacimiento mediante llamadas telefónicas quincenales durante una temporada invernal. Se registraron datos clínicos y epidemiológicos en cuestionarios prediseñados. Se exploró y recogió el aspirado nasofaríngeo (ANF) cuando el paciente presentó sintomatología compatible con una infección respiratoria. El diagnóstico de los virus más comunes se realizó con inmunofluorescencia directa (IFD) y amplificación genómica (PCR). Resultados: Fueron seleccionados 316 recién nacidos. Se realizaron 1.865 llamadas telefónicas (mediana 4), y 106 visitas, en 89 de las cuales se confirmó la enfermedad. Los síntomas más frecuentes fueron rinitis (91 %) y tos (69 %). El diagnóstico clínico principal fue infección respiratoria de vías altas (82 %); 17 de 72 ANF realizados (23,2 %) fueron positivos. Se detectaron rinovirus (41,1 %) y VRS (35,2 %). Ingresaron un 16 % (17/106) de los niños atendidos por enfermedad (el 5,3 % de la cohorte), diagnosticados de síndrome febril y de bronquiolitis. No encontramos ningún factor epidemiológico asociado con la infección respiratoria viral en los casos positivos. Conclusiones: En nuestro medio las infecciones respiratorias de los lactantes son en su mayoría banales y no precisan atención hospitalaria. El rinovirus y el VRS son los principales agentes etiológicos. No se encontraron factores epidemiológicos relacionados con la infección respiratoria asociada a virus (AU)

Tratamiento del síndrome de Tourette y su comorbilidad: presentación de 17 casos / Treatment of Tourette syndrome and its comorbidity: experience with 17 cases

Introducción. Presentamos las características clínicas y trastornos comórbidos asociados y evaluamos los resultados de los tratamientos farmacológicos empleados en 17 pacientes con síndrome de Tourette (ST). Material y métodos. Revisión retrospectiva de los pacientes pediátricos diagnosticados de ST en nuestro hospital entre 1998 y 2004. Resultados. De los 17 pacientes, 16 son varones y sólo 1 mujer, con edades actuales comprendidas entre 7 y 17 años. Los trastornos comórbidos más frecuentes fueron el trastorno por deficit de atención con hiperactividad (TDAH) en 9 pacientes (53 Ofo), conductas obsesivo-compulsivas en 8 (48 %) Y ansiedad en 7 (41 %). Presentaban problemas de aprendizaje 7 (41 %), de los cuales 5 asociaban un TDAH y 1 un trastorno obsesivo-compulsivo (TOC) severo. Encontramos efectos farmacológicos adversos severos que obligaron a la retirada de la medicación en los 2 casos tratados con haloperidol (ambos de tipo extrapiramidal) y en 3 de los 7 (43 %) de los tratados con pimozida (1 de ellos de tipo extrapiramidal). No ocurrieron efectos extrapiramidales con los neurolépticos atípicos, pero fueron frecuentes la sedación y el aumento de peso. Siete pacientes fueron tratados con metilfenidato, sin empeoramiento de los tics. Conclusiones. En nuestra serie los trastornos comórbidos más frecuentes fueron el TDAH, conductas obsesivo-compulsivas, ansiedad y dificultades en el aprendizaje. Los neurolépticos atípicos fueron mejor tolerados que los clásicos, aunque la incidencia de efectos adversos es también elevada. El metilfenidato no se ha asociado a empeoramiento de los tics
