AIM The aim of this study was to describe the magnetic resonance imaging (MRI) findings and the neurological and neuropsychological outcomes in paediatric, diarrhoea-associated haemolytic-uraemic syndrome (D+HUS) with central nervous system impairment treated with eculizumab, a monoclonal antibody. METHOD The 14-month single-centre prospective study(More)
The aim was to localize the interictal cerebral perfusion abnormalities of focal cortical dysplasia (FCD) in children with Arterial Spin Labeling MRI (ASL) in a retrospective study of nine consecutive children explored with multimodal investigation during interictal periods. We analyzed brain morphology with a 1.5T MRI and a dedicated protocol for epilepsy.(More)
AIM To address risk of first or recurrent cerebral haemorrhage in children with sickle-cell disease (SCD) who are being managed with modern stroke prevention strategies. METHOD A systematically followed SCD paediatric cohort was retrospectively studied over a 9-year period. Haemorrhagic risk was defined as intracranial haemorrhage occurrence or(More)
Human beings are social animals. This ability to live together is ensured by cognitive functions, the neuroanatomical bases of which are starting to be unraveled by MRI-based studies. The regions and network engaged in this process are known as the "social brain ". The core of this network is the superior temporal sulcus (STS), which integrates sensory and(More)
OBJECTIVE The aim of this prospective study was to analyze the changes in cerebrospinal fluid (CSF) distribution after endoscopic third ventriculocisternostomy (ETV). METHODS Twenty-two hydrocephalic children (eight boys, aged 3 months to 17 years) candidates for ETV were studied by preoperative brain magnetic resonance (MR) and repeated post-ETV MRs at(More)
Autistic spectrum disorder (ASD) is characterised by qualitative alterations in reciprocal social interactions. Some recent studies show alterations in gaze patterns during social perception and rest-functional abnormalities in the 'social brain network'. This study investigated: i) social perception gaze patterns in children with ASD and controls, ii) the(More)
Transcranial magnetic stimulation (TMS) is currently used for cognitive studies and investigated as a treatment for psychiatric disorders. Because of the cortex variability, the coil positioning stage is difficult and should be improved by using individual neuroimaging data. Sophisticated and expensive neuronavigation systems have been developed to guide(More)
