Mutations in SCN2A cause epilepsy syndromes of variable severity including neonatal-infantile seizures. In one case, we previously described additional childhood-onset episodic ataxia. Here, we corroborate and detail the latter phenotype in three further cases. We describe the clinical characteristics, identify the causative SCN2A mutations and determine(More)
SUMMARY During the past decade, the application of advanced MR imaging techniques in neuropsychiatric disorders has seen a rapid increase. Disease-specific alterations in brain function can be assessed by fMRI. Structural GM and WM properties are increasingly investigated by DTI and voxel-based approaches like VBM. These methods provide neurobiologic(More)
INTRODUCTION Arginine vasopressin (AVP) is increasingly used to restore mean arterial pressure (MAP) in low-pressure shock states unresponsive to conventional inotropes. This is potentially deleterious since AVP is also known to reduce cardiac output by increasing vascular resistance. The effects of AVP on blood flow to vital organs and cardiac performance(More)

OBJECTIVES Proteomic technologies based on mass spectrometry are increasingly used as a valuable tool in clinical research allowing high-throughput protein and peptide profiling to be undertaken. Whilst previous research has focussed the application of this novel technology on the study of patients with disorders compared to comparable individuals from the(More)
Thirty patients with multiple sclerosis were randomized to 500 or 2,000 mg of methylprednisolone (MP) over 5 days. They were prospectively studied neuropsychologically before and at days 6 and 60 after onset of the therapy, using a double-blind study design. Patients showed selective deterioration of declarative memory retrieval at day 6, which was fully(More)
Three cases of brain stem dysfunction associated with cervical manipulation are reported. The patients exhibited a spectrum of neurologic deficits, ranging from minimal to severe. Literature concerning the relationship of neck movement and vertebrobasilar blood flow is reviewed and an explanation for the ischemia leading to dysfunction is proposed.
BACKGROUND AND PURPOSE Loss of integrity in nonlesional white matter occurs as a fundamental feature of multiple sclerosis in adults. The purpose of our study was to evaluate DTI-derived measures of white matter microstructure in children with MS compared with age- and sex-matched controls by using tract-based spatial statistics.
