Usefulness of electroencephalography for the management of epilepsy in emergency departments. / Utilidad del electroencefalograma en el manejo de la epilepsia en el Servicio de Urgencias.

INTRODUCTION: Electroencephalography (EEG) is an essential diagnostic tool in epilepsy. Its use in emergency departments (ED) is usually restricted to the diagnosis and management of non-convulsive status epilepticus (NCSE). However, EDs may also benefit from EEG in the context of other situations in epilepsy. METHODS: We conducted a retrospective observational study using the clinical histories of patients treated at our hospital's ED for epileptic seizures and suspicion of NCSE and undergoing EEG studies in 2015 and 2016. We collected a series of demographic and clinical variables. RESULTS: Our sample included 87 patients (mean age of 44 years). Epileptic seizures constituted the most common reason for consultation: 59.8% due to the first episode of epileptic seizures (FES), 27.6% due to recurrence, and 12.6% due to suspected NCSE. Interictal epileptiform discharges (IED) were observed in 38.4% of patients reporting FES and in 33.3% of those with a known diagnosis of epilepsy. NCSE was confirmed by EEG in 36.4% of all cases of suspected NCSE. Presence of IED led to administration of or changes in long-term treatment in 59.8% of the patients. CONCLUSIONS: EEG is a useful tool for seizure management in EDs, not only for severe, sudden-onset clinical situations such as NCSE but also for diagnosis in cases of non-affiliated epilepsy and in patients experiencing the first episode of epilepsy.

Emergency electroencephalogram: Usefulness in the diagnosis of nonconvulsive status epilepticus by the on-call neurologist. / Uso de la electroencefalografía urgente por el neurólogo de guardia: utilidad en el diagnóstico del estatus epiléptico no convulsivo.

INTRODUCTION: We aim to describe the use of emergency electroencephalogram (EmEEG) by the on-call neurologist when nonconvulsive status epilepticus (NCSE) is suspected, and in other indications, in a tertiary hospital. SUBJECTS AND METHODS: Observational retrospective cohort study of emergency EEG (EmEEG) recordings with 8-channel systems performed and analysed by the on-call neurologist in the emergency department and in-hospital wards between July 2013 and May 2015. Variables recorded were sex, age, symptoms, first diagnosis, previous seizure and cause, previous stroke, cancer, brain computed tomography, diagnosis after EEG, treatment, patient progress, routine control EEG (rEEG), and final diagnosis. We analysed frequency data, sensitivity, and specificity in the diagnosis of NCSE. RESULTS: The study included 135 EEG recordings performed in 129 patients; 51.4% were men and their median age was 69 years. In 112 cases (83%), doctors ruled out suspected NCSE because of altered level of consciousness in 42 (37.5%), behavioural abnormalities in 38 (33.9%), and aphasia in 32 (28.5%). The EmEEG diagnosis was NCSE in 37 patients (33%), and this was confirmed in 35 (94.6%) as the final diagnosis. In 3 other cases, NCSE was the diagnosis on discharge as confirmed by rEEG although the EmEEG missed this condition at first. EmEEG performed to rule out NCSE showed 92.1% sensitivity, 97.2% specificity, a positive predictive value of 94.6%, and a negative predictive value of 96%. CONCLUSIONS: Our experience finds that, in an appropriate clinical context, EmEEG performed by the on-call neurologist is a sensitive and specific tool for diagnosing NCSE.

Emergencias neuropediatricas en niños atendidos en el Hospital Universitario de Maracaibo / Neuropaediatric emergencies in children admitted to the Hospital Universitario, Maracaibo, Venezuela

Durante los últimos años se ha observado un incremento en el número de consultas en los servicios de emergencias pediátricas de forma proporcional al incremento de las consultas por motivos neurológicos. Objetivos: Analizar la demanda de la actividad asistencial neuropediátrica y conocer los motivos de consultas más frecuentes y su distribución epidemiológica. Métodos: Estudio observacional de cohorte histórica mediante el registro prospectivo durante un año en el servicio de Emergencia Pediátrica del Hospital Universitario de Maracaibo. Resultados: Se solicitó evaluación neuropediátrica a 172 pacientes constituyendo el 0,17 % de todas las emergencias entre 0 y 15 años de edad, predominando los lactantes (39%) y niños varones (53,5%). Las crisis convulsivas son el motivo de consulta más frecuente (45%), seguidas del retraso psicomotor y la sospecha de encefalopatías estáticas. La epilepsia fue el principal diagnóstico de ingreso (23%) y egreso (25%) seguido de meningitis bacteriana aguda. Conclusiones: Las urgencias neurológicas constituyen un porcentaje significativo del total de las urgencias pediátricas. Son muchos los motivos de consulta y es rol del pediatra de emergencias solicitar la valoración especializada. Las crisis convulsivas, retraso psicomotor, infecciones del sistema nervioso central, síncope y cefalea constituyen los cinco principales motivos de consulta. Sin embargo la demora psicomotora no constituye una urgencia, por lo que el pediatra debe estar en capacidad de tomar la decisión acertada a quien debe derivar y solicitar la consulta por el especialista de forma inmediata.

In recent years there has been an increase in the number of consultations in pediatric emergency services in proportion to the increase in consultations for neurological reasons.Objectives: To analyze the demand of neuropaediatric care, and to determine the most frequent reasons for neuropediatric consultations. Methods: Historical cohort observational study by means of a prospective registry during one year in the Pediatric Emergency Service of the University Hospital of Maracaibo, Venezuela. Results: Neuropediatric evaluation was requested for 172 patients, 0.17% of all emergencies, ages from 0 to 15 years, predominantly infants (39%) and boys (53.5%). Seizures were the most frequent reason for consultation (45%), followed by psychomotor retardation and suspected static encephalopathies. Epilepsy was the most frequent diagnosis at admission (23%) and discharge (25%), followed by acute bacterial meningitis. Conclusions: Neurological emergencies constitute a significant percentage of all pediatric emergencies. There are many reasons for consultation and the pediatrician's role is to decide who deserves specialized neurologic care or who may be derived for an outpatient emergency assessment. Seizures, psychomotor retardation, central nervous system infections, syncope and headache, were the five main reasons for consultation; however psychomotor delay does not constitute an emergency, so the pediatrician should be able to decide which patient should be derived to the neuropediatrician.

Análisis de las consultas neurológicas en el Servicio de Urgencia de un hospital terciario / Analysis of the neurologic consultations in the Emergency Deparment at a tertiary hospital

Introducción: Las urgencias neurológicas constituyen el 10-15% de las urgencias médicas. Los principales motivos de consulta son la enfermedad cerebrovascular, crisis epilépticas y cefalea. El Hospital Dr. Hernán Henríquez A. (HHHA) comenzó con neurólogos en el Servicio de Urgencia Adultos (SUA) en horario hábil, en abril de 2011. En julio de 2013 se iniciaron turnos con neurólogo 24/7, presenciales en el SUA. Objetivo: Describir el perfil clínico de las consultas neurológicas en el SUA de nuestro centro. Método: Muestra noprobabilística, por conveniencia, de las consultas realizadas en el Turno N°1, del SUA-HHHA, entre octubre de 2013 y septiembre de 2014. El análisis estadístico se realizó con el software STATA 12.0. Resultados: Se registraron 1.080 consultas en el período. 51,2% fueron mujeres. Promedio de edad = 58 años (DE = 20,2). El 36,7% de las consultas se realizó en horario inhábil. Los diagnósticos más frecuentes fueron infarto cerebral (30,7%), epilepsia (15%) y cefalea (11,3%). El 34,6% de los pacientes fue dado de alta; 25,8% se hospitalizó en el Servicio de Medicina Interna; 21% fue derivado a otros hospitales; 12% fue derivado a otros especialistas y 5,7% ingresó a la Unidad de Paciente Crítico. 0,83% de los pacientes falleció en el SUA. Conclusiones: Los principales motivos de consulta neurológica en nuestro Servicio de Urgencia fueron enfermedades cerebrovasculares, epilepsia y cefalea. Debido a que más de un tercio de las consultas ocurre en horario inhábil, se justifica el sistema de neurología 24/7 presencial en el Servicio de Urgencia.

Introduction: Neurological emergencies constitute 10-15% of medical emergencies. The main reasons for consultation are cerebrovascular disease, seizures and headaches. Dr. Hernan Henriquez Hospital (HHHA) began with neurologists in the Adult Emergency Service in April 2011. In July 2013 24/7 neurology shifts at emergency room were added. Objective: To describe the clinical profile of neurologic consultations at our emergency center. Method: A convenience sample of consultations on shift No. 1, at the Adult Emergency Service HHHA between October 2013 and September 2014. The statistical analysis was performed using STATA 12.0 software. Results: 1,080 consultations were recorded in theperiod. 51.2% were women. Mean age = 58 years (SD = 20.2). 36.7% of consultations are conducted in a non-business hour. The most frequent diagnoses were stroke (30.7%), epilepsy (15%) and headache (11.3%). 34.6% ofpatients were discharged; 25.8% were hospitalized in the Internal Medicine dept; 21% were referred to other hospitals; 12% were referred to other specialists and 5.7% were admitted to Critical Patient Unit. 0.83% of the patients died in the SUA. Conclusions: The main reasons for neurological consultation at our Emergency Service were cerebrovascular disease, epilepsy and headaches. Because more than a third of consultations occur on non-schedule hours, neurology system 24/7 shifts are justified in the Emergency Service.

Workload of on-call emergency room neurologists in a Spanish tertiary care centre. A one-year prospective study.

INTRODUCTION: Population ageing, the rising demand for healthcare, and the establishment of acute stroke treatment programs have given rise to increases in the number and complexity of neurological emergency cases. Nevertheless, many centres in Spain still lack on-call emergency neurologists. METHODS: We conducted a retrospective study to describe the role of on-call neurologists at Hospital General Universitario Gregorio Marañón, a tertiary care centre in Madrid, Spain. Sociodemographic characteristics, most common pathologies, diagnostic tests, and destination of the patients attended were recorded daily using a computer database. Results were compared with the general care data from the emergency department. RESULTS: The team attended 3234 patients (3.48% of the emergency department total). The mean number of patients seen per day was 11.15. The most frequent pathologies were stroke (34%), epilepsy (16%) and headache (8%). The mean stay in the emergency department was 7.17 hours. Hospital admission rate was 40% (7.38% of emergency hospital admissions). The main destinations for admitted patients were the stroke unit (39.5%) and the neurology department (33%). Endovascular or thrombolytic therapies were performed on 76 occasions. Doctors attended 70% of the patients during on-call hours. CONCLUSIONS: Emergency neurological care is varied, complex, and frequently necessary. Neurological cases account for a sizeable percentage of both patient visits to the emergency room and the total number of emergency admissions. The current data confirm that on-call neurologists available on a 24-hour basis are needed in emergency departments.
