RESUMO
OBJECTIVE: Access to epilepsy specialist care is not uniform in the USA, with prominent gaps in rural areas. Understanding the reasons for nonattendance at epilepsy appointments may help identify access hurdles faced by patients. This study was undertaken to better understand clinic absenteeism in epilepsy and how it may be influenced by telemedicine. METHODS: In this retrospective study, social determinants of health were collected for all adult patients scheduled in epilepsy clinic, as either an in-person or telemedicine appointment, at University of Kentucky between July 2021 and December 2022. The primary outcome measure was attendance or absence at the appointment. Subgroup analyses were done to better understand the drivers of attendance at telemedicine visits and evaluate telemedicine utilization by underserved populations. RESULTS: A total of 3025 patient encounters of in-person and telemedicine visits were included. The no-show rate was significantly higher for in-person visits (32%) compared with telemedicine visits (20%, p < .001). A nominal logistic regression model identified seven factors increasing risk of absenteeism, including in-person visits, prior missed appointments, longer lead times to appointment, Medicaid/Medicare as payors, no significant other, lower mean annual income, and minority race. For each $10 000 increase in mean annual income, the odds of missing the appointment decreased by 8% (odds ratio = .92, 95% confidence interval = .89-.96, p < .001). Forty-one percent of underserved population opted for telemedicine visits, and they had a lower no-show rate (22%) as compared with in-person visits (33%, p < .001). Predictors of no-shows to televisits (1382) included Medicare/Medicaid coverage (as opposed to private insurance), no significant others, and a history of missing appointments. SIGNIFICANCE: Telemedicine is effective at improving attendance, overcoming socioeconomic hurdles, and widening access to epilepsy care, particularly among underserved populations. Access to telecare depends on insurance coverage and emphasizes the need to include telemedicine in insurance plans to ensure uniform access to high-quality epilepsy care, irrespective of socioeconomic status.

The incidence of new-onset seizures, which we defined as de novo seizures occurring within 4 weeks of receiving any of the US Food and Drug Administration-approved COVID-19 vaccinations as reported in patient-reported data compiled in the US Centers for Disease Control and Prevention Vaccine Adverse Events Reporting System Data (CDC VAERS), has not been explored. The VAERS database contains de-identified patient-reported adverse events following vaccination and represents post-marketing surveillance and analysis of vaccine safety. After adjusting for time at risk, this resulted in estimated incidence rates of 3.19 seizures per 100 000 persons per year for the COVID-19 vaccine and 0.090 seizures per 100 000 persons per year for the influenza vaccines. A data-driven, individualized dataset that is comprehensive and coupled with a longitudinal follow-up in larger numbers of vaccinated individuals is needed to expand on our preliminary findings of vaccine-related seizures.

PURPOSE OF THE RESEARCH: The geriatric population is the fastest-growing population in the United States and the impact of incident epilepsy on the cognitively intact geriatric population is not well-studied. Understanding how epilepsy affects the elderly is important to improve the quality of treatment and care for our aging population. This study sought to address the impact of incident epilepsy on the perceived Quality of Life (QOL) in cognitively intact elderly using the SF-36 questionnaire. METHODS: Nine hundred and twenty-seven participants were assessed from a community-based cohort. Based on a history of subsequent development of new-onset seizures, participants were divided into two groups, an incident seizure group that developed new-onset seizures after 65â¯years of age and the control group without incident seizures. Of this, six hundred eleven were analyzed with the SF-36 questionnaire after excluding for cognitive decline and inconsistent medical data. PRINCIPAL RESULTS: Statistically significant differences were found in 9 items on SF-36, involving perception of increased physical disability (pâ¯<â¯0.01; t-test), frailty (pâ¯<â¯0.04; t-test), emotional health limitations (pâ¯<â¯0.03; t-test), anxiety and sadness (pâ¯<â¯0.04; t-test), problems interfering with social activities (pâ¯<â¯0.0001; t-test). No between-group differences were found for demographic variables including age, education, gender, or minority status. Among the 611 subjects who remained cognitively normal across all longitudinal visits, 12 reported a history of new-onset seizures. Ten of these 12 subjects were seizure free as a result of treatment, with only 2 experiencing recent seizures. The incidence of seizures in our population was 300 per 100,000 person years. MAJOR CONCLUSIONS: This study identified the elderly population with incident epilepsy as a subgroup with an unmet health need, and healthcare professionals should address the potential impact of seizures with their geriatric patients to ensure comprehensive care.

It is presumed that the EEG records only cerebral activity. However, frequently it can include other electrical activities, referred to as noise or artifact, which are not of cerebral origin. In the last few decades, evolution in digital technology has greatly improved the ability to record and display interpretable EEG. With the widespread availability of prolonged EEG recording, new artifacts have been described. The addition of concomitant video with audio during recordings has allowed in most instances to determine the source of certain artifacts. One of the challenges of interpreting EEGs consists of identifying artifacts correctly. Some of the EEG artifacts are so distinctive in appearance that the experienced reader can readily identify them. It is not uncommon for normal EEGs to be overinterpreted, especially by inexperienced readers. Failing to identify artifacts correctly can lead to "over reading" a study and doing so can result in misdiagnosis of epilepsy. This in turn can result in inappropriate treatments that ultimately can have serious clinical implications. This review will provide a description of the most commonly encountered artifacts that mimic spike or sharp waves, also referred to as interictal epileptiform discharges. In addition, we will describe troubleshooting approaches to eliminate these artifacts whenever possible. Artifacts that mimic ictal discharges will be reviewed in a different section.

There is concern that bluish skin discoloration associated with ezogabine treatment could be permanent. We present a case of ezogabine-induced skin discoloration that resolved completely after discontinuation. A 55-year-old woman started ezogabine 400 mg three times a day at age 41. Bluish pigmentation over the toe nails, finger nails, around eyes and over and around lips was first noted after 5 years of treatment. Ezogabine was discontinued eight years after initiation. Skin discoloration improved within 6 months and completely resolved within 6 years of discontinuation. This case suggests that ezogabine-induced discoloration is reversible after discontinuation of treatment.
RESUMO
INTRODUCTION: Valproic acid is a versatile antiepileptic drug that is often used in the acute care setting. Intravenous valproic acid lends itself well to a continuous infusion as it exhibits a relatively short half-life. We evaluated the pharmacokinetics and clinical efficacy of continuous infusion valproic acid in hospitalized patients with migraine and seizures. METHODS: A retrospective cohort study was performed utilizing information from the medical records of patients receiving an intravenous continuous infusion of valproic acid. Patients were included if they were aged 1 month to 85 years and they received a continuous infusion of valproic acid. Therapeutic response, common adverse effects, and the pharmacokinetic profile of valproic acid were evaluated. RESULTS: Continuous infusion valproic acid led to a concentration within the desired range (50-100 µg/ml) in 83.4% of patients, a rate that was higher in pediatric patients. The clinical response rate was also higher in pediatric patients with seizures or migraines and appeared to be better when the concentration was >75 µg/ml. Analysis of safety parameters suggests similar safety considerations to valproic acid when administered via intermittent infusion. CONCLUSIONS: Continuous infusion valproic acid appears to be a safe, effective, and predictable manner by which to administer valproic acid to pediatric and adult patients admitted to the hospital.
