Post–epilepsy surgery psychogenic nonepileptic seizures

Summary

Objectives

We investigated the prevalence of post–epilepsy surgery psychogenic nonepileptic seizures (PNES) in patients with drug-resistant epilepsy and the possible influence of risk factors on these seizures.

Methods

In this retrospective study, we examined data from all patients with a clinical diagnosis of drug-resistant epilepsy who underwent epilepsy surgery at Graduate Hospital and the Jefferson Comprehensive Epilepsy Center between 1986 and 2016. Postsurgical outcome was identified for up to 15 years after surgery. Diagnosis of PNES was verified in ...

Association of HLA genotypes with phenobarbital hypersensitivity in children

Summary

Objective

Phenobarbital hypersensitivity is one of the common drug hypersensitivity syndromes in children. Clinical symptoms of phenobarbital hypersensitivity vary from maculopapular rashes (MPs) to severe cutaneous adverse drug reactions (SCARs) including drug reactions with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). Drug hypersensitivity has been demonstrated to be associated with variations in the HLA genotypes. This study was to investigate the association between the variations of HLA genotypes and phenobarbital hypersensitivity in ...

Regional and global connectivity disturbances in focal epilepsy, related neurocognitive sequelae, and potential mechanistic underpinnings

Summary

Epilepsy is among the most common brain network disorders, and it is associated with substantial morbidity and increased mortality. Although focal epilepsy was traditionally considered a regional brain disorder, growing evidence has demonstrated widespread network alterations in this disorder that extend beyond the epileptogenic zone from which seizures originate. The goal of this review is to summarize recent investigations examining functional and structural connectivity alterations in focal epilepsy, including neuroimaging and electrophysiologic studies utilizing model-based or data-driven ...

Epilepsy due to mutations in the mitochondrial polymerase gamma (POLG) gene: A clinical and molecular genetic review

Summary

We performed a systematic review of the clinical, molecular, and biochemical features of polymerase gamma (POLG)–related epilepsy and current evidence on seizure management. Patients were identified from a combined electronic search of articles using Ovid Medline and Scopus databases, published from January 2000 to January 2015. Only patients with a confirmed genetic diagnosis of POLG mutations were considered. Seventy-two articles were included for analysis. We identified 128 pathogenic variants in 372 patients who had POLG-related epilepsy. Among ...

The spectrum of epilepsy and electroencephalographic abnormalities due to SHANK3 loss-of-function mutations

Summary

Objective

The coincidence of autism with epilepsy is 27% in those individuals with intellectual disability.1 Individuals with loss-of-function mutations in SHANK3 have intellectual disability, autism, and variably, epilepsy.2-5 The spectrum of seizure semiologies and electroencephalography (EEG) abnormalities has never been investigated in detail. With the recent report that SHANK3 mutations are present in approximately 2% of individuals with moderate to severe intellectual disabilities and 1% of individuals with autism, determining the spectrum of seizure semiologies and electrographic abnormalities ...

Continuous spike-waves during slow-wave sleep in a mouse model of focal cortical dysplasia

Summary

Objective

To examine if mice with focal cortical dysplasia (FCD) develop spontaneous epileptic seizures and, if so, determine the key electroencephalography (EEG) features.

Methods

Unilateral single freeze lesions to the S1 region (SFLS1R) were made in postnatal day 0–1 pups to induce a neocortical microgyrus in the right cortical hemisphere. Continuous 24-h recordings with intracranial EEG electrodes and behavioral tests were performed in adult SFLS1R and sham-control mice to assess neurologic status.

Results

A high percentage of adult SFLS1R animals ...

Long-term exposure and safety of lacosamide monotherapy for the treatment of partial-onset (focal) seizures: Results from a multicenter, open-label trial

Summary

Objective

To assess long-term use and safety of lacosamide (LCM) ≤800 mg/day monotherapy in patients with partial-onset seizures (POS) enrolled previously in a historical-controlled, conversion-to-monotherapy study (SP902; NCT00520741).

Methods

Patients completing or exiting SP902 with LCM as monotherapy or as adjunctive therapy were eligible to enter this 2-year open-label extension (OLE) trial (SP904; NCT00530855) at a starting dose ±100 mg/day of their final SP902 dose. Investigators could adjust the LCM dose to 100–800 mg/day and add up to two ...

Genetic risk factors for antiepileptic drug–induced hypersensitivity reactions in Israeli populations

Summary

The human leukocyte antigen (HLA) alleles B*15:02 and A*31:01 have been identified as predictive markers of adverse cutaneous effects of carbamazepine and phenytoin in Asian and North European populations, respectively. Our aim was to estimate the distribution of these alleles in Jewish and Arab populations in Israel. The HLA-B*15:02 and HLA-A*31:01 carrier rate was estimated based on data from the Hadassah Bone Marrow Registry. Data on Stevens-Johnson syndrome (SJS)– and toxic epidermal necrolysis (TEN)–related hospitalizations were obtained ...
