INTRODUCTION Since its first description at the beginning of the 19th century, greater awareness of this disorder has been achieved, becoming nowadays a recognized but sometimes underdiagnosed cause of ischemic stroke in childhood. AIM. To describe a population of children with cerebral venous thrombosis, analyzing clinical presentation, risk factors,(More)
We report the clinical, biochemical and molecular findings on the first documented patient with 4-hydroxybutyric aciduria (4-HBA, McKusick 271980) from Uruguay. The patient displayed a severe picture and turned out to be homozygous for a mutation (c.1226G < A) previously shown to be associated with null enzyme activity.
Recently characterized as an immune-mediated channelopaty, Isaacs' syndrome (also known as acquired neuromyotonia) was first described in 1961 in two men with persistent, generalized muscle stiffness, in addition to spontaneous, rapid discharges of motor-unit potentials on electromyography. In the peripheral nervous system, antibodies targeted to(More)
Bilateral segmental neurofibromatosis is a rare condition characterized by the occurrence of neurofibromas and/or café-au-lait spots limited to an area or segment of the body bilaterally. It is caused by a postzygotic mutation in the neurofibromatosis type I gene, resulting in a phenotype of genetic mosaicism. This report describes a case of bilateral(More)
Standard intelligence scales require both verbal and manipulative responses, making it difficult to use in cerebral palsy and leading to underestimate their actual performance. This study aims to compare three intelligence tests suitable for the heterogeneity of cerebral palsy in order to identify which one(s) could be more appropriate to use. Forty-four(More)
INTRODUCTION Cranio-cervical arterial dissections are a recognized cause of ischemic stroke in childhood, with an approximate incidence of 0.4 to 20%. AIM. To describe a population of children with cranio-cervical arterial dissections, analyzing clinical presentation, risk factors, angiographic findings, evolution and treatment. PATIENTS AND METHODS A(More)
Rett syndrome (RTT) is an early-onset neurodevelopmental disorder that almost exclusively affects girls and is totally disabling. Three genes have been identified that cause RTT: MECP2, CDKL5 and FOXG1. However, the etiology of some of RTT patients still remains unknown. Recently, next generation sequencing (NGS) has promoted genetic diagnoses because of(More)
