Randomized Controlled Trial Clinical Trial
Intravenous immunoglobulin treatment in chronic inflammatory demyelinating polyneuropathy. A double-blind, placebo-controlled, cross-over study.
Thirty patients with definite or probable chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) of chronic progressive (16 patients) or relapsing (14 patients) course were randomly assigned to receive intravenous immunoglobulin (IvIg) 0.4 g per kg body weight or a placebo treatment on 5 consecutive days in a double-blind, cross-over trial. Neurological function was monitored by serial quantitative assessments [neurological disability score (NDS); clinical grade (CG) and grip strength (GS) measurements] and by electrophysiological studies before and after each treatment period. Twenty-five patients completed both treatment periods. ⋯ All 10 patients have been maintained and stabilized with IvIg pulse therapy of 1 g per kg body weight or less, given as a single infusion prior to the expected relapse. A beneficial response to IvIg was found to be most likely in patients with acute relapse or with disease of one year or less. Patients with predominantly sensory signs did not improve.

We studied 31 consecutive patients with temporal and extratemporal epilepsy who underwent presurgical evaluation with stereotaxic depth EEG (SEEG) to assess the relationships between amygdalo-hippocampal (AM-HF) atrophy and the location of SEEG seizure onset and SEEG interictal abnormalities. Scalp EEG recordings with sphenoidal electrodes had shown bitemporal ictal or interictal epileptic abnormalities in all. Patients underwent high quality MRI scans, including MRI volumetric measurements of mesial temporal structures. ⋯ We conclude that unilateral mesial atrophy predicts ipsilateral mesial SEEG seizure onset despite bitemporal extracranial EEG foci. However, in patients with significant bilateral mesial atrophy, SEEG seizures may originate from either side, even in the presence of significant asymmetry. Finally, the identification of unilateral mesial atrophy has prognostic importance.
