BACKGROUND Congenital muscular dystrophies (CMD) with reduced glycosylation of alpha-dystroglycan (alpha-DG) are a heterogeneous group of conditions associated with mutations in six genes encoding proven or putative glycosyltransferases. OBJECTIVES The aim of the study was to establish the prevalence of mutations in the six genes in the Italian population(More)
BACKGROUND Mutations in genes encoding subunits of the tRNA-splicing endonuclease (TSEN) complex were identified in patients with pontocerebellar hypoplasia 2 (PCH2) and pontocerebellar hypoplasia 4 (PCH4). OBJECTIVE We report molecular genetic findings in 12 Italian patients with clinical and MRI findings compatible with PCH2 and PCH4. METHODS We(More)
20 children with severe cerebral palsy and history of urinary incontinence and recurrent urinary infection underwent radio--and neuro-urologic evaluation. Vesico-ureteral reflux was found in 7 patients. In 9, who had presented episodes of urine sub-retention, a urodynamic study demonstrated detrusor muscle hyperreflexia in all, deficit of vesicourethral(More)
BACKGROUND Hemiplegic migraine (HM) is a rare variety of migraine with aura, characterized by motor deficits during the aura, often beginning in childhood. The hemiplegic attacks can be severe and prolonged but the prognosis is usually good. Data on neuroimaging, including diffusion-weighted imaging (DWI) and spectroscopy, during prolonged attacks of HM are(More)
Coenzyme Q10 (CoQ10) deficiency has been associated with various clinical phenotypes, including an infantile multisystem disorder. The authors report a 33-month-old boy who presented with corticosteroid-resistant nephrotic syndrome in whom progressive encephalomyopathy later developed. CoQ10 was decreased both in muscle and in fibroblasts. Oral CoQ10(More)
Metachromatic leukodystrophy (MLD) is an autosomal recessive disease with well-documented intracranial findings on neuroimaging both by computed tomography (CT) and MRI. We describe the first case of late infantile MLD with spinal involvement revealed by MRI as marked contrast enhancement of nerve roots at the level of the cauda equina.
Neuropsychological investigations of FMR1 premutation carriers without FXTAS present one domain resulting in contradictory findings, namely that of mathematical skills. One reason for this might be that standard clinical batteries used so far may be inadequate to uncover precise deficits within specific mathematical skills. In fact, these batteries do not(More)
Forty-two children born to HIV positive mothers (29 infected at different stages of the disease, according to the Disease Control Classification Centers, and 13 noninfected) underwent evaluation using a battery of neuropsychological tests. Executive function impairments were present in all infected children, whereas memory and visuo-prassic deficits were(More)
We evaluated the visual outcome of a cohort of children with neurofibromatosis type 1 (NF1) and optic pathway glioma (OPG) treated according to standardized therapeutic guidelines. The study population consisted of all consecutive patients with NF1 and OPG referred to a specialized pediatric neuro-oncology program between 1994 and 2004. Treatment was(More)
