Spatial and Temporal Characteristics of Historical Oil and Gas Wells in Pennsylvania: Implications for New Shale Gas Resources.

Recent large-scale development of oil and gas from low-permeability unconventional formations (e.g., shales, tight sands, and coal seams) has raised concern about potential environmental impacts.

Parieto-occipital lobe epilepsy caused by a POLG1 compound heterozygous A467T/W748S genotype.

We describe a 16-year-old woman with a rare POLG1 A467T/W748S genotype, with a wide range of neurological manifestations, including focal parieto-occipital lobe seizures, migraine headaches, cerebellar ataxia, sensory-motor axonal neuropathy, and impairment of visual perception and cognitive function. Treatment of epilepsy in patients with a POLG1 compound heterozygous A467T/W748S genotype is very challenging; the epilepsy may preferentially respond to sodium channel blockers. The POLG1-related syndrome has a variable clinical course, and disease morbidity and mortality may be correlated with the genotype.

Hemispheric lateralization and language skill coherence in temporal lobe epilepsy.

Patients with an early onset of temporal lobe epilepsy (TLE) are at an increased risk for language reorganization. It is unknown whether this reorganization involves a full shift of all language skills to the contralateral hemisphere, or whether it can be partial and involve only a subset of language skills. In this study we report dominance concordance patterns for five separate language skills measured during the Intracarotid Amobarbital Procedure (IAP) for 124 TLE patients.

Self-perception of seizure precipitants and their relation to anxiety level, depression, and health locus of control in epilepsy.

Background: The aim of this study was to determine the prevalence and nature of self-perceived seizure precipitants in epilepsy patients, and evaluate whether anxiety level, depression, or health locus of control influence self-perception of seizure precipitants.

Methods: Adults aged 18 and older who had epilepsy for at least 1 year were recruited in either the inpatient epilepsy monitoring unit or the outpatient epilepsy clinic at Thomas Jefferson University in 2006. Patients anonymously filled out a questionnaire, which included data about age, sex, education, seizure control, and three questionnaires including identification of seizure precipitants, Hospital anxiety and depression (HAD) scale, and Form C of the multidimensional health locus of control (MHLC).

Health locus of control in patients with epilepsy and its relationship to anxiety, depression, and seizure control.

Objective: A person's health locus of control orientation is one of several factors that determine which health-related behaviors a person will perform. The aim of this study was to determine the health locus of control in patients with epilepsy and its relationship to anxiety, depression, and seizure control.

Methods: Adults aged 18 and older who had had epilepsy for at least 1 year were recruited in either the inpatient epilepsy monitoring unit or the outpatient epilepsy clinic at Thomas Jefferson University in 2006.
