Background: Diabetes is a hidden epidemic and the most common metabolic disorder in the world. Immune dysfunction (cellular and humoural) is one of the consequences of diabetes, including defects of phagocyte function, notably in chemotaxis, phagocytosis, and killing. Results of studies on phagocyte respiratory burst activity, however, have been contradictory. We studied the respiratory burst o...
Population spikes vary in size during prolonged epileptic ("ictal") discharges, indicating variations in neuronal synchronization. Here we investigate the role of changes in tissue electrical resistivity in this process. We used the rat hippocampal slice, low-Ca(2+) model of epilepsy and measured changes in pyramidal layer extracellular resistance during the course of electrographic seizures. D...
PURPOSE To describe the EEG pattern of seizures in patients with benign childhood epilepsy with centro-temporal spikes (BCECTS). METHODS The clinical and EEG data of 701 BCECTS patients with at least a 3 years follow-up were reviewed from 10 epilepsy centers. RESULTS Thirty-four seizures were recorded in 30 patients. Four different ictal EEG patterns (A-D) were identified. The most frequent...
PURPOSE To elucidate the localization of ictal EEG activity, and correlate it to semiological features in self-limited epilepsy with centrotemporal spikes (formerly called "benign epilepsy with centrotemporal spikes"). METHODS We have performed ictal electric source imaging, and we analysed electroclinical correlations in three patients with self-limited epilepsy with centrotemporal spikes. ...
OBJECTIVE The epilepsies associated with the tuberous sclerosis complex (TSC) are very often refractory to medical therapy. Surgery for epilepsy is an effective alternative when the critical link between the localization of seizure onset in the scalp and a particular cortical tuber can be established. In this study we perform analysis of ictal and interictal EEG to improve such link. METHODS ...
High resolution electroencephalography (HR-EEG) combined with source localization methods has mainly been used to study interictal spikes and there have been few studies comparing source localization of scalp ictal patterns with depth EEG. To address this issue, 10 patients with four different scalp ictal patterns (ictal spikes, rhythmic activity, paroxysmal fast activity, obscured) were invest...
Rationale: The development of closed-loop devices suitable for use in the treatment of epileptic patients would very likely rely on the adequate development of paradigms able to forecast the occurrence of seizures. In this paper, we studied the usefulness of approximate enthropy, of a non-linear paradigm, in this patient population. Methods: We applied approximate entropy (ApEn) analysis to stu...
Application of 4-aminopyridine (4AP, 50 microM) to combined slices of adult rat hippocampus-entorhinal cortex-induced ictal and interictal epileptiform discharges, as well as slow field potentials that were abolished by the mu-opioid agonist [D-Ala2,N-Me-Phe4,Gly-ol5] enkephalin (DAGO, 10 microM) or the GABAA receptor antagonist bicuculline methiodide (BMI, 10 microM); hence, they represented s...
