Marcie L King, Daniel Tranel
OBJECTIVE: Psychological adjustment following surgery for epilepsy has been assessed primarily with self-report measures. In the current work, we investigated pre- to postoperative changes in various dimensions of personality and behavior from the perspective of a well-known family member or friend for 27 patients operated on for medically intractable epilepsy. METHODS: For each patient, a close family member or friend ("informant") provided pre- and postoperative ratings on five dimensions of personality and behavior...

Alejandro L Escalaya, Jorge G Burneo
There is increasing evidence of the existence of refractoriness to treatment with antiepileptic medications in those with NCC-related epilepsy. We performed a systematic review with the objective to determine the role of a cysticercotic lesion in this group of patients. We sought those manuscripts, including case reports, describing patients with NCC-related medically-intractable epilepsy who underwent epilepsy surgery and were seizure-free a year after. Only 10 manuscripts fulfilled inclusion and exclusion criteria...

AIM: To study the clinical, electrophysiological and imaging characteristics of patients with unilateral mesial temporal lobe epilepsy (MTLE) with contralateral ictal onset on scalp EEG, viz. 'burned-out hippocampus' syndrome (MTLE-BHS). METHODS: MTLE-BHS was defined as TLE with unilateral hippocampal sclerosis (HS) without any dual pathology on MRI and contralateral ictal onset on scalp EEG, unlike in classical hippocampal sclerosis (HS). Consecutive "MTLE-BHS" patients evaluated at our Centre for Comprehensive Epilepsy Care from January 2005 to July 2014 were studied...

There are extensive studies evaluating mesial temporal sclerosis (MTS) in adults and limited studies in children, with adolescents being included within both patient populations. Our aim was to evaluate predictors of surgical outcome solely in adolescent patients with MRI- and pathology -proven MTS. The Yale Epilepsy Surgery Database was reviewed from 1987 to 2012 for adolescent patients with confirmed MTS on MRI and pathology who underwent temporal lobectomy and had greater than two-year postsurgical follow-up...

The mammalian target of rapamycin (mTOR) has been demonstrated to mediate multidrug resistance in various tumors by inducing P-glycoprotein (P-gp) overexpression. Here, we investigated the correlation between the mTOR pathway and P-gp expression in pharmacoresistant epilepsy. Temporal cortex specimens were obtained from patients with refractory mesial temporal lobe epilepsy (mTLE) and age-matched controls who underwent surgeries at West China Hospital of Sichuan University between June 2014 and May 2015. We established a rat model of epilepsy kindled by coriaria lactone (CL) and screened pharmacoresistant rats (non-responders) using phenytoin...

BACKGROUND: Versive seizure characterized by conjugate eye movement during epileptic seizure has been considered commonly as one of the most valuable semiological signs for epilepsy localization, especially for frontal lobe epilepsy. However, thelateralizing and localizing significance of ictaleye deviation has been questioned by clinical observation of a series of focal epilepsy studies, including frontal, central, temporal, parietal and occipital epilepsy. CASE PRESENTATION: Two epileptic cases characterized by ipsiversive eye deviation as initial clinical sign during the habitual epileptic seizures are presented in this paper...

BACKGROUND: Agenesis of the corpus callosum can occur in individuals with epilepsy, either in isolation or as part of various neurological conditions, such as Aicardi syndrome. In this study, we evaluated the clinical and neuroradiological differences between children with nonsyndromic agenesis of the corpus callosum and those with Aicardi syndrome. METHODS: We evaluated 31 children with epilepsy and agenesis of the corpus callosum (11 males, 20 females), 14 of whom had Aicardi syndrome (all females)...

Transplant patients need lifelong immunosuppressive medication, but this reduces their defense mechanisms, making them prone to viral infections and reactivations. We aimed to clarify the prevalence and clinical manifestations of the human herpes virus 6 (HHV-6) infection in children after pediatric solid organ transplants. Clinical findings and viral loads were compared between primary HHV-6 infections and reactivations. The study comprised 47 kidney, 25 liver, and 12 heart transplant patients who underwent surgery from 2009 to 2014...

BACKGROUND: Antifibrinolytic therapy significantly decreases blood loss and transfusion in pediatric cranial vault reconstructive surgery; however, concern regarding the side effects profile limits clinical use. AIMS: The aim was to utilize the Pediatric Craniofacial Surgery Perioperative Registry database to identify the safety profile of antifibrinolytic therapy for cranial vault reconstructive surgery by reporting the incidence of adverse events as they relate to exposure to tranexamic acid and aminocaproic acid compared to no exposure to antifibrinolytics...

During the last 20 years, predictive modeling in epilepsy research has largely been concerned with the prediction of seizure events, whereas the inference of effective brain targets for resective surgery has received surprisingly little attention. In this exploratory pilot study, we describe a distributional clustering framework for the modeling of multivariate time series and use it to predict the effects of brain surgery in epilepsy patients. By analyzing the intracranial EEG, we demonstrate how patients who became seizure free after surgery are clearly distinguished from those who did not...

A girl aged 3 months presented with multiple seizures within 12 hours and was noted to have a palpable swelling over the right temporal region. MRI of the brain revealed a large right frontotemporal tumour, suggestive of supratentorial primitive neuroectodermal tumour. She underwent a stealth-guided craniotomy and debulking of the tumour. Histopathology and immunochemistry of the specimen, however, indicated a high-grade tumour with glioblastoma and neuroblastic components. She underwent adjuvant chemotherapy following the surgery and is well at 7-month follow-up...

OBJECTIVE: Driven by advances in genomic technology and reduction in costs, next-generation sequencing (NGS) is venturing into routine clinical care. The 'real-world' clinical utility of NGS remains to be determined in focal epilepsies, which account for 60% of all epilepsies and for which the importance of genetic factors is just beginning to emerge. We investigated the diagnostic yield and management implications of whole exome sequencing (WES)-based screening of selected genes in the routine care of common focal epilepsies suspected to have a genetic basis...

OBJECTIVE: Recent evidence suggests a metabolic contribution of cytochrome P450 enzymes (CYPs) to the drug-resistant phenotype in human epilepsy. However, the upstream molecular regulators of CYP in the epileptic brain remain understudied. We therefore investigated the expression and function of pregnane xenobiotic (PXR) and glucocorticoid (GR) nuclear receptors in endothelial cells established from post-epilepsy surgery brain samples. METHODS: PXR/GR localization was evaluated by immunohistochemistry in specimens from subjects who underwent temporal lobe resections to relieve drug-resistant seizures...

Surgical resection represents a successful strategy to achieve seizure control in patients with drug resistant epilepsy. In the last years increasing importance has been recognized to pathological substrate for epilepsy classifications and for predicting seizure and neuropsychological outcome after surgery. The current histopathological classifications of epilepsy-associated abnormalities certainly represent an amazing effort to overcome the limits of the previous classifications and constitute a formidable tool in the management of patients after epilepsy surgery...

Up to one-third of patients with epilepsy are medically intractable and need resective surgery. To be successful, epilepsy surgery requires a comprehensive preoperative evaluation to define the epileptogenic zone (EZ), the brain area that should be resected to achieve seizure freedom. Due to lack of tools and methods that measure the EZ directly, this area is defined indirectly based on concordant data from a multitude of presurgical non-invasive tests and intracranial recordings. However, the results of these tests are often insufficiently concordant or inconclusive...

Neurologic complications in polytrauma can be classified by etiology and clinical manifestations: neurovascular, delirium, and spinal or neuromuscular problems. Neurovascular complications include ischemic strokes, intracranial hemorrhage, or the development of traumatic arteriovenous fistulae. Delirium and encephalopathy have a reported incidence of 67-92% in mechanically ventilated polytrauma patients. Causes include sedation, analgesia/pain, medications, sleep deprivation, postoperative state, toxic ingestions, withdrawal syndromes, organ system dysfunction, electrolyte/metabolic abnormalities, and infections...
