We aimed to assess long-term seizure outcome and risk factors for seizure recurrence in a cohort of patients who have undergone extratemporal resection for management of refractory seizures. ⋯ Distinction between subtypes of focal cortical dysplasia, which can be made using magnetic resonance imaging (MRI) criteria, may be useful for preoperative prognostication. Early seizures after surgery are not benign and may be markers of factors that contribute to seizure recurrence. Most patients achieve substantial reduction in seizure frequency. Further study of the significance of this reduction in terms of surgical "success" or otherwise is required.

People with epilepsy are more likely than healthy people to experience comorbidities and complications in various medical situations. However, the prevalence of postoperative complications, mortality, and use of medical resources in surgical patients with epilepsy has not been studied. The purpose of this study is to examine whether epilepsy is an independent risk factor for postoperative adverse outcomes of patients receiving major surgery. ⋯ Stroke was identified as the most significant postoperative complication for surgical patients with epilepsy. Patients, especially those with previous hospitalization or emergency visits due to the disease, confronted significantly higher postoperative complication rates, and consumed more in-hospital medical resources without differences in overall mortality rates. Further revision of health care standards to provide early recognition of postoperative complications and better management for surgical patients with epilepsy is needed.

To date, magnetic resonance imaging (MRI)-based studies of the cerebral cortex in mesial temporal lobe epilepsy (MTLE) have focused primarily on investigating cortical volume and thickness. However, volume is a composite of surface area and thickness, each reflecting distinct neurobiologic and genetic processes. The goal of this study was to investigate cerebral cortex (1) surface area, (2) surface geometric distortion, and (3) thickness in MTLE with hippocampal sclerosis (HS). ⋯ Our findings indicate that contraction in surface area, rather than cortical thinning, explains ipsilateral mesial and anterior temporal lobe atrophy in patients with MTLE with HS. Furthermore, the alterations in surface geometry indicate folding abnormality involving the same regions. Cortical surface changes may represent sequelae of the disease or deviant cortical development.

The number of times that a published article is cited is one indicator of its scientific impact. An article is termed a "Citation Classic" once it has accumulated more than 400 citations. Trends in these highly cited works allow projection of future directions of high-impact research within a field. ⋯ There were also considerably fewer epilepsy-specific Citation Classics compared to other disciplines. In this study, we find that the Citation Classics of epilepsy comprise a heterogeneous group of articles and that changes in the trends of these highly cited works represent the evolution of epilepsy research over time. The results of this study should inform the academic community and provide a guide of essential literature for scientists who are engaged in epilepsy research.

Status epilepticus (SE) is associated with significant mortality and morbidity. A reliable prognosis may help better manage medical resources and treatment strategies. We examined the role of preexisting comorbidities on the outcome of patients with SE, an aspect that has received little attention to date. ⋯ As compared with the simplest predictive model (including demographics and deadly etiology), adding SE severity and comorbidities resulted in an improved predictive performance (C statistics 0.84 vs. 0.77 for mortality, and 0.86 vs. 0.82. for return to clinical baseline); comorbidities, however, were not independently related to outcome. Considering comorbidities and clinical presentation, in addition to age and etiology, slightly improves the prediction of SE outcome with respect to both survival and functional status. This analysis also emphasizes the robust predictive role of etiology and age.
