Many important questions regarding pathophysiology and treatment of cerebral sinovenous thrombosis need clarification and may depend on further knowledge on the etiology, site, extension and recanalization of the thrombosis. We studied these variables in a cohort of children and adolescents from seven Portuguese Centers. We conclude from our results that the deep venous system and the superior longitudinal sinu...

O AVC em idade pediátrica é uma situação pouco frequente, representando a dissecção arterial uma pequena percentagem da sua etiologia. Os autores apresentam o caso de um adolescente com AVC isquémico provocado por dissecção da artéria vertebral. A sintomatologia incluiu cefaleias acompanhadas de náuseas e vómitos, tonturas, alteração do estado de consciência, discurso lentificado e flexão cervical intermitente...
In this work we explored the role of the 3'UTR of the MECP2 gene in patients with clinical diagnosis of RTT and mental retardation; focusing on regions of the 3'UTR with almost 100% conservation at the nucleotide level among mouse and human. By mutation scanning (DOVAM-S technique) the MECP2 3'UTR of a total of 66 affected females were studied. Five 3'UTR variants in the MECP2 were found (c.1461+9G>A, c.1461+98...
Introducción Los tics son el trastorno del movimiento más frecuente en la edad pediátrica. Es común la existencia de historia familiar de tics y de antecedentes familiares y personales de trastornos neurocomportamentales. Los tics pueden comprometer de modo importante las actividades de la vida diaria del individuo. Objetivo Estudio de las características de los tics de niños y adolescentes de la Consulta de Ne...

O síndrome de Joubert (SJ) é uma patologia autossómica recessiva rara, que resulta de uma anomalia da morfogénese do Sistema Nervoso Central. Clinicamente, cursa com hipotonia, anomalias do ritmo respiratório, apraxia oculomotora, ataxia, e atraso de desenvolvimento psicomotor. Imagiologicamente (TAC, RMN cerebral) caracteriza-se pelo sinal do “dente molar” resultante da agenesia do vermis cerebeloso Os autores...

Mutations in the coding sequence of the methyl-CpG-binding protein 2 gene (MECP2), which cause Rett syndrome (RTT), have been found in male and female autistic subjects without, however, a causal relation having unequivocally been established. In this study, the MECP2 gene was scanned in a Portuguese autistic population, hypothesizing that the phenotypic spectrum of mutations extends beyond the traditional diag...
RESUMO Os tiques são o distúrbio do movimento mais comum em crianças e adolescentes. São mais frequentes no sexo masculino que no feminino, e podem começar a manifestar-se já no primeiro ano de vida. O espectro de gravidade dos tiques é muito amplo, podendo passar praticamente despercebidos ou, pelo contrário, apresentar evidentes repercussões negativas nos vários aspectos da vida dos doentes. A sua associação ...
