Introduction. Autoimmune thyroiditis is the most common cause of hypothyroidism in children. Clinical diagnosis depends on biochemical condition and monitoring is essential to adopt therapeutic measures and ensure proper growth and development. Objective. To describe the clinical progression of autoimmune thyroiditis in children and adolescents. Design. Retrospective, longitudinal series of cases study. Setting. Department of Endocrinology, Instituto Nacional de Salud del Niño, Lima, Peru (a teaching institution). Participants. Children and adolescents suffering of autoimmune thyroiditis. Interventions. Sixty-five patients -58 women and 7 men- under the age of 18 suffering of autoimmune thyroiditis and admitted between 2000-2012 were followed with clinical and biochemical evaluations over one year; carriers of genetic syndromes or with type 1 diabetes mellitus were excluded. Main outcom...

La nefropatía constituye la complicación más grave de la diabetes mellitus tipo 1 (DMt1) siendo una de las manifestaciones iniciales la microalbuminuria. Objetivos: Determinar el comportamiento de los factores epidemiológicos, clínicos y bioquímicos en el desarrollo de microalbuminuria en pacientes con DMt1. Diseño: Estudio de casos y controles. Lugar: Servicio de Endocrinología del Instituto Nacional de Salud del Niño, Lima, Perú. Participantes: Pacientes diabéticos tipo 1 menores de 18 años. Intervenciones: Se estudió 64 pacientes portadores de DMt1, 22 con microalbuminuria y 42 sin esta manifestación, que constituyeron los casos y controles respectivamente. Se consignó como factores epidemiológicos la edad al diagnóstico, tiempo de evolución, género, antecedentes familiares de diabetes, nefropatía, dislipidemia, hipertensión arterial; como factores clínicos, el e...

Objectives: To describe the clinical and biochemical response to treatment of hyperthyroidism. Design: Retrospective study. Setting: Instituto Nacional de Salud del Niño, Lima, Peru. Participants: children. Methods: From 1996 to 2007 32 patients with diagnosis of hyperthyroidism were studied. Remission was defined when patients were asymptomatic and biochemically euthyroid 6 months after the end of treatment; relapse when altered hormone levels were found after this period of time. Main outcome measures: Remission or relapse following treatment. Results: Mean age at diagnosis was 10.5 years (3.2-17.9 years), 26 patients (81.2 %) were female; 13 (40.6 %) were pubertal and 18 (59.3%) prepubertal. The most frequent symptoms and signs were: goiter, sweating, nervousness, weight loss, tachycardia and exophthalmos. Methimazole was used as first therapeutic option. Initial dose was 0.78mg/kg/d...
