Background and Purpose-There are few data on the effectiveness and side effects of antiepileptic drug therapy after intracerebral hemorrhage. We tested the hypothesis that antiepileptic drug use is associated with more complications and worse outcome after intracerebral hemorrhage. Methods-We prospectively enrolled 98 patients with intracerebral hemorrhage and recorded antiepileptic drug use as either prophylactic or therapeutic along with clinical characteristics. Antiepileptic drug administration and free phenytoin serum levels were retrieved from the electronic medical records. Patients with depressed mental status underwent continuous electroencephalographic monitoring. Outcomes were measured with the National Institutes of Health Stroke Scale and modified Rankin Scale at 14 days or discharge and the modified Rankin Scale at 28 days and 3 months. We constructed logistic regression models for poor outcome at 3 months with a forward conditional model.
Results-Seven
Although there is general agreement regarding the indications for ICU cEEG, there is substantial interinstitutional variability in how the procedure is performed.
ObjectivesThe Automatic Stimulation Mode (AutoStim) feature of the Model 106 Vagus Nerve Stimulation (VNS) Therapy System stimulates the left vagus nerve on detecting tachycardia. This study evaluates performance, safety of the AutoStim feature during a 3‐5‐day Epilepsy Monitoring Unit (EMU) stay and long‐ term clinical outcomes of the device stimulating in all modes.Materials and MethodsThe E‐37 protocol (NCT01846741) was a prospective, unblinded, U.S. multisite study of the AspireSR® in subjects with drug‐resistant partial onset seizures and history of ictal tachycardia. VNS Normal and Magnet Modes stimulation were present at all times except during the EMU stay. Outpatient visits at 3, 6, and 12 months tracked seizure frequency, severity, quality of life, and adverse events.ResultsTwenty implanted subjects (ages 21–69) experienced 89 seizures in the EMU. 28/38 (73.7%) of complex partial and secondarily generalized seizures exhibited ≥20% increase in heart rate change. 31/89 (34.8%) of seizures were treated by Automatic Stimulation on detection; 19/31 (61.3%) seizures ended during the stimulation with a median time from stimulation onset to seizure end of 35 sec. Mean duty cycle at six‐months increased from 11% to 16%. At 12 months, quality of life and seizure severity scores improved, and responder rate was 50%. Common adverse events were dysphonia (n = 7), convulsion (n = 6), and oropharyngeal pain (n = 3).ConclusionsThe Model 106 performed as intended in the study population, was well tolerated and associated with clinical improvement from baseline. The study design did not allow determination of which factors were responsible for improvements.
Inter-rater agreement among EEGers in both academic and PP settings varies considerably. Practice location, years of EFT, and board certification are associated with significantly higher performance for IED detection in routine scalp EEG. Continued medical education of PP neurologists and neurologists without EFT is needed to improve routine scalp EEG interpretation skills. The performance of automated detection algorithms is approaching that of human experts.
Contraceptive counseling by epileptologists and specific mention of an IUD is significantly associated with patient selection of an IUD as a contraceptive method. This suggests that neurologists can play an important role in patients' contraceptive choices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
