N-ACETYL-ASPARTATE ABNORMALITIES IN INTERNAL-TEMPORAL EPILEPTICUS FOCUS USING PROTON MAGNETIC-RESONANCE SPECTROSCOPY
1995
International audience; Abstract: The aim of this study was to characterize the neurochemical abnormalities related to N-acetyl-aspartate which is a neuronal marker, within an epilepticus focus located in the internal-temporal area, using proton magnetic resonance spectroscopy, Eleven patients,with a mono-hippocampal epilepticus focus on clinical and per-critical electroencephalographical criteria, were matched with II controls by age, sex and laterality. Proton spectroscopy of a volume of 8 cm(3) was performed within the ipsilateral and the contralateral internal-temporal area and within the 2 hippocampus of controls. Volumetry of the ipsilateral and the contralateral hippocampus and of th…
PRELIMINARY-OBSERVATIONS OF METABOLIC CHARACTERIZATION OF BILATERAL TEMPORAL EPILEPTIC FOCUS, USING PROTON MAGNETIC-RESONANCE SPECTROSCOPY - 3 CASES
1994
International audience; Abstract: The authors report the case of 3 patients with bilateral temporal lobe epilepsy demonstrated by EEG and sphenoidal electrodes. Two out of the 3 patients presented with childhood febrile convulsions. Their neurological and mental examination was normal. EEG showed spikes within the anterior part of the 2 temporal lobes. CT scan and MRI showed no atrophic lesion within the 2 temporal lobes. Proton magnetic resonance spectroscopy, performed within a cube of 8 cube-centimetres localized in the anterior part of the 2 temporal lobes showed a significant decrease of N-acetyl-aspartate in the 2 temporal lobes of the 3 cases, compared with controls matched with age,…
Walking Speed as an Alternative Measure of Functional Status in Patients with Lumbar Spinal Stenosis
2019
Objective The main objective was to compare estimated walking perimeter (WP) and actual WP during a free walking test (6-minute walk test [6MWT]) in patients with lumbar spinal stenosis (LSS). The second objective was to describe the correlation between measured gait parameters and functional parameters. Methods This was a single-center prospective study including 38 patients with symptomatic LSS (23 men, 15 women; mean age, 69.3 ± 7.9 years). The intervention was the 6MWT. For the main outcome measure, patients were first asked to verbally estimate their WP. Then, WP was evaluated using a 6MWT at a self-selected speed. In the absence of need to stop, and if a distance of 500 m was not reac…
