results of the latarjet procedure for recurrent anterior dislocation of the shoulder in Patients with Epilepsy
Journal of Bone and Joint Surgery-british Volume, 2012Co-Authors: Patric Raiss, A Lin, N Mizuno, Barbara Melis, Gilles WalchAbstract:A total of 12 epileptic Patients (14 shoulders) with recurrent seizures and anterior dislocations of the shoulder underwent a Latarjet procedure and were reviewed at a mean of 8.3 years (1 to 20) post-operatively. Mean forward flexion decreased from 165° (100° to 180°) to 160° (90° to 180°) (p = 0.5) and mean external rotation from 54° (10° to 90°) to 43° (5° to 75°) (p = 0.058). The mean Rowe score was 76 (35 to 100) at the final follow-up. Radiologically, all shoulders showed a glenoid-rim defect and Hill-Sachs lesions pre-operatively. Osteo-arthritic changes of the glenohumeral joint were observed in five shoulders (36%) pre-operatively and in eight shoulders (57%) post-operatively. Re-dislocation during a seizure occurred in six shoulders (43%). Five of these Patients underwent revision surgery using a bone buttress from the iliac crest and two of these Patients re-dislocated due to a new seizure. Due to the unacceptably high rate of re-dislocation after surgery in these Patients, the most important means of reducing the incidence of further dislocation is the medical management of the seizures. The Latarjet procedure should be reserved for the well-controlled Patient with Epilepsy who has recurrent anterior dislocation of the shoulder during activities of daily living.

cortical chimera states predict epileptic seizures
Chaos, 2019Co-Authors: Claudia Lainscsek, Nuttida Rungratsameetaweemana, Sydney S Cash, Terrence J SejnowskiAbstract:A chimera state is a spatiotemporal pattern of broken symmetry, where synchrony (coherent state) and asynchrony (incoherent state) coexist. Here, we report chimera states in electrocorticography recordings preceding, by several hours, each of seven seizures in one Patient with Epilepsy. Before the seizures, the onset channels are not synchronized, while the remaining channels are synchronized. During the seizures, this pattern of behavior flips and the nononset channels show a more asynchronous behavior. At a seizure offset, synchrony can be observed that might facilitate termination.A chimera state is a spatiotemporal pattern of broken symmetry, where synchrony (coherent state) and asynchrony (incoherent state) coexist.

event related fmri with simultaneous and continuous eeg description of the method and initial case report
NeuroImage, 2001Co-Authors: Louis Lemieux, Afraim Salekhaddadi, Oliver Josephs, Philip J Allen, Nathan Toms, C Scott, K Krakow, Robert Turner, D R FishAbstract:We report on the initial imaging findings with a new technique for the simultaneous and continuous acquisition of functional MRI data and EEG recording. Thirty-seven stereotyped interictal epileptiform discharges (spikes) were identified on EEG recorded continuously during the fMRI acquisition on a Patient with Epilepsy. Localization of the BOLD activation associated with the EEG events was consistent with previous findings and EEG source modeling. The time course of activation was comparable with the physiological hemodynamic response function (HRF). The new methodology could lead to novel and important applications in many areas of neuroscience.
