Epilepsy and antiseizure medications increase all-cause mortality in dialysis patients in the United States.

Seizures have been associated with uremia, but there are few data regarding the prevalence, treatment, and outcomes of patients with end-stage renal disease (ESRD) with epilepsy compared to those with ESRD without epilepsy. Here we conducted a retrospective cohort study using the United States Renal Data System to assess mortality and antiseizure medication prescriptions among patients with ESRD with and without a diagnosis of epilepsy. A modified Poisson regression with a robust variance was used to estimate the association between epilepsy status and mortality, and evaluate effect modification by neurology consultation. Additionally antiseizure medications were assessed in relation to mortality among those with epilepsy. Of 148,294 patients with ESRD in the cohort, 13,094 (8.8%) met a claims-based definition for epilepsy. Among those with epilepsy, 80.9% filled an anticonvulsant or hydantoin prescription in 2013-2014, compared to 33.3% without epilepsy. After adjustment for confounders, the mortality risk among those with epilepsy was 1.11 (95% confidence interval: 1.07, 1.14) times higher than those without. An epilepsy diagnosis was associated with a 15% increase in mortality risk among patients who did not have a neurology consultation (relative risk: 1.15 [95% confidence interval: 1.10, 1.20]), but this risk was attenuated among patients with a neurology consultation (1.07 [1.03, 1.11]). Prescription of gabapentin to patients with an epilepsy diagnosis compared to other antiseizure medications was associated with increased mortality (1.08 [1.01, 1.15]). Thus, patients with ESRD treated with dialysis have a high prevalence of epilepsy, which was associated with increased mortality risk compared to those without epilepsy. Hence, appropriate multidisciplinary care, treatment, and medication selection may reduce mortality among dialysis patients with epilepsy.

Electroencephalographic Reporting for Refractory Status Epilepticus.

PURPOSE: We aimed to determine whether clinical EEG reports obtained from children in the intensive care unit with refractory status epilepticus could provide data for comparative effectiveness research studies. METHODS: We conducted a retrospective descriptive study to assess the documentation of key variables within clinical continuous EEG monitoring reports based on the American Clinical Neurophysiology Society's standardized EEG terminology for children with refractory status epilepticus from 10 academic centers. Two pediatric electroencephalographers reviewed the EEG reports. We compared reports generated using free text or templates. RESULTS: We reviewed 191 EEG reports. Agreement between the electroencephalographers regarding whether a variable was described in the report ranged from fair to very good. The presence of electrographic seizures (ES) was documented in 46% (87/191) of reports, and these reports documented the time of first ES in 64% (56/87), ES duration in 72% (63/85), and ES frequency in 68% (59/87). Reactivity was documented in 16% (31/191) of reports, and it was more often documented in template than in free-text reports (40% vs. 14%, P = 0.006). Other variables were not differentially reported in template versus free-text reports. CONCLUSIONS: Many key EEG features are not documented consistently in clinical continuous EEG monitoring reports, including ES characteristics and reactivity assessment. Standardization may be needed for clinical EEG reports to provide informative data for large multicenter observational studies.

Parental ranking of terms describing nonepileptic events.

Paroxysmal nonepileptic events of psychogenic etiology in children and adolescents are common. Patients and their parents are often confused by the terminology used to describe these events. This can lead to frustration and may result in the failure to obtain the necessary nonpharmacologic treatment. Various terms are used to describe such events, some of which might be considered offensive to some individuals. Surveys from 146 parents or guardians of patients identified from a general pediatric clinic, a general neurology clinic, and a pediatric epilepsy monitoring unit were completed with the aim of determining which words and phrases were least offensive. It was determined that nonepileptic events, functional seizures, and nonepileptic attack disorder were the least offensive labels; whereas "it is all in his or her head," hysterical seizures, and psychogenic seizures were the most offensive terms. This is the only study of its type in the pediatric population. Although each child and family requires individualized communication, we hope that this article will provide useful information to guide the practicing pediatric neurologist in informing families that their children are having events of nonepileptic etiology.
