Crisis epilépticas en urgencias: aspectos clínicos y diagnósticos de una serie de 153 pacientes / Seizures in the Emergency Department: Clinical and diagnostic data from a series of 153 patients

Introducción: Las crisis epilépticas son un motivo de ingreso frecuente en urgencias y requieren una actuación diagnóstico-terapéutica precoz y precisa. Nuestro objetivo fue describir las características clínico-evolutivas de una serie de pacientes con crisis epilépticas atendidos en urgencias.MétodosEstudio observacional retrospectivo de todos los pacientes con crisis epilépticas que ingresaron en urgencias y fueron atendidos por neurología de guardia, de febrero a agosto de 2017.ResultadosSe incluyeron 153 pacientes, correspondientes al 9,9% del total de urgencias neurológicas. La mediana de edad fue de 58 años, el 52,3% fueron mujeres y el 51% tenía antecedente de epilepsia. El 82,4% de las crisis tuvo un inicio focal y la etiología más frecuente fue la enfermedad cerebrovascular (24,2%). Doce pacientes se complicaron con estatus epiléptico (7,8%), lo que se relacionó con mayor puntuación en la escala ADAN (p < 0,001) y con antecedente de epilepsia refractaria (p = 0,002). La mortalidad hospitalaria fue del 3,7%; se asoció a mayor edad (p = 0,049) y a estatus epiléptico (p = 0,018). El 80% de los pacientes sin epilepsia conocida recibió el diagnóstico de epilepsia en urgencias, todos iniciaron tratamiento. El índice Kappa de concordancia para el diagnóstico de epilepsia en urgencias, comparado con el diagnóstico tras un año de seguimiento en la unidad de epilepsia fue 0,45 (se modificó el diagnóstico en el 20% de los pacientes).ConclusionesLas crisis epilépticas constituyen una urgencia neurológica frecuente, con potenciales complicaciones y una morbimortalidad relevante. En pacientes sin epilepsia conocida es apropiado realizar el diagnóstico de epilepsia en urgencias, pero es recomendable un seguimiento posterior en consultas especializadas. (AU)

Introduction: Seizures are a frequent reason for admission to emergency departments and require early, precise diagnosis and treatment. The objective of this study was to describe the clinical and prognostic characteristics of a series of patients with seizures attended at our hospital's emergency department.MethodsWe performed a retrospective, observational study of all patients with seizures who were admitted to our hospital's emergency department and attended by the on-call neurology service between February and August 2017.ResultsWe included 153 patients, representing 9.9% of all neurological emergency department admissions. The median age was 58 years, 52.3% of patients were women, and 51% had history of epilepsy. Onset was focal in 82.4% of cases, and the most frequent aetiology was cerebrovascular disease (24.2%). Twelve patients (7.8%) developed status epilepticus, which was associated with higher scores on the ADAN scale (P < .001) and with history of refractory epilepsy (P = .002). The in-hospital mortality rate was 3.7%, and in-hospital mortality was associated with older age (P = .049) and status epilepticus (P = .018). Eighty percent of patients with no history of epilepsy were diagnosed with epilepsy at the emergency department; all started treatment. The kappa coefficient for epilepsy diagnosis in the emergency department compared to diagnosis after one year of follow-up by the epilepsy unit was .45 (diagnosis was modified in 20% of patients).ConclusionsSeizures are a frequent neurological emergency with potential complications and considerable morbidity and mortality rates. In patients with no known history of epilepsy, the condition may be diagnosed in the emergency department, but follow-up at specialised epilepsy units is recommended. (AU)

Stereoelectroencephalography in the preoperative assessment of patients with refractory focal epilepsy: experience at an epilepsy centre.

OBJECTIVE: Stereoelectroencephalography (SEEG) is a technique for preoperative evaluation of patients with difficult-to-localise refractory focal epilepsy (DLRFE), enabling the study of deep cortical structures. The procedure, which is increasingly used in international epilepsy centres, has not been fully developed in Spain. We describe our experience with SEEG in the preoperative evaluation of DLRFE. MATERIAL AND METHODS: In the last 8 years, 71 patients with DLRFE were evaluated with SEEG in our epilepsy centre. We prospectively analysed our results in terms of localisation of the epileptogenic zone (EZ), surgical outcomes, and complications associated with the procedure. RESULTS: The median age of the sample was 30 years (range, 4-59 years); 27 patients (38%) were women. Forty-five patients (63.4%) showed no abnormalities on brain MR images. A total of 627 electrodes were implanted (median, 9 electrodes per patient; range, 1-17), and 50% of implantations were multilobar. The EZ was identified in 64 patients (90.1%), and was extratemporal or temporal plus in 66% of the cases. Follow-up was over one year in 55 of the 61 patients undergoing surgery: in the last year of follow-up, 58.2% were seizure-free (Engel Epilepsy Surgery Outcome Scale class I) and 76.4% had good outcomes (Engel I-II). Three patients (4.2%) presented brain haemorrhages. CONCLUSION: SEEG enables localisation of the EZ in patients in whom this was previously impossible, offering better surgical outcomes than other invasive techniques while having a relatively low rate of complications.

Estereoelectroencefalografía en la evaluación prequirúrgica de epilepsias focales refractarias: experiencia de un centro de epilepsia / Stereoelectroencephalography in the preoperative assessment of patients with refractory focal epilepsy: Experience at an epilepsy centre

Objetivo: La estereoelectroencefalografía (E-EEG) es una técnica de evaluación prequirúrgica en pacientes con epilepsia focal refractaria de difícil localización (EFRDL) que permite explorar con electrodos profundos regiones cerebrales de difícil acceso y la profundidad de la corteza. Esta técnica, en auge en centros internacionales, apenas se ha desarrollado en España. Describimos nuestra experiencia con la E-EEG en la evaluación de pacientes con EFRDL. Material y métodos: En los últimos 8 años, 71 pacientes con EFRDL fueron evaluados con E-EEG en nuestro centro. Analizamos prospectivamente los resultados obtenidos en la localización, los resultados quirúrgicos y las complicaciones asociadas a la técnica. Resultados: La mediana de edad fue de 30 años (rango 4-59 años), 27 pacientes eran mujeres (38%). La RM cerebral fue negativa en 45 pacientes (63,4%). Se implantaron 627 electrodos (mediana de 9 electrodos por paciente, rango 1-17), con un 50% de implantaciones multilobares. En 64 (90,1%) pacientes se localizó la zona epileptógena (ZE), siendo extratemporal o temporal plus en el 66% de los casos. En 55 pacientes de los 61 intervenidos el seguimiento fue superior al año: en el último año de seguimiento 32/55 pacientes (58,2%) estaban libres de crisis (Engel I) siendo los resultados favorables (Engel I-II) en el 76,4% de las intervenciones. Tres pacientes (4,2%) presentaron una hemorragia cerebral. Conclusión: La E-EEG permite localizar la ZE en pacientes en quienes anteriormente no era posible, ofreciendo unos resultados quirúrgicos superiores a otras técnicas invasivas y una tasa de complicaciones relativamente baja.

The importance of timing in epilepsia partialis continua.

INTRODUCTION: Timing is one of the most important modifiable prognostic factors in the management of status epilepticus. Epilepsia partialis continua (EPC) is a status epilepticus subtype of highly variable, occasionally prolonged, duration. The aim of this study was to analyse the relationship between EPC duration and outcomes. METHODS: We performed an observational prospective study of all patients with EPC admitted to our tertiary hospital between 1 September 2017 and 1 September 2018. RESULTS: The sample included 10 patients, of whom 9 were women; median age was 74 years. The most frequent aetiology was cerebrovascular disease (n = 6). EPC onset occurred outside the hospital in 5 patients, with a median time to hospital admission of 4 hours. The median time to treatment onset (TT) for all patients was 12.3 hours. The median time from treatment onset to EPC control (TC) was 30 hours; TC showed a strong positive correlation with TT (Spearman's rho = 0.88). Six patients presented hyperglycaemia at onset; this was positively correlated with TC (rho = 0.71). All 6 patients with hyperglycaemia presented a brain injury explaining the EPC episode. CONCLUSIONS: Delays were observed in different phases of EPC management, which was related to longer duration of the episode. Glycaemia was also related to episode duration, probably acting as a triggering factor rather than as the aetiology.

Status epilepticus without impairment of consciousness: Long-term outcomes according to duration.

OBJECTIVE: The point after which non-convulsive status epilepticus (NCSE) can cause permanent damage remains to be elucidated. The aim of this study was to analyze the association between time to resolution and long-term outcomes in NCSE. METHODS: We performed a retrospective study of all patients with focal NCSE without consciousness impairment at two tertiary care hospitals in Spain. All the data were registered prospectively and the study period was December 2014-May 2018. We collected information on demographics, SE etiology, time to administration of different lines of treatment, time to NCSE resolution, and outcomes at discharge, 1 year, and 4 years. Clinical outcome was prospectively categorized as good (return to baseline function) or poor (new disability and death). RESULTS: Seventy-four patients with a mean (±SD) age of 63.4 ±â€¯17.5 years and a mean follow-up time of 2.4 ±â€¯2.2 years were studied. A poor outcome at discharge was associated with a potentially fatal etiology (p < 0.001), EMSE score (Epidemiology-based Mortality Score in Status Epilepticus) (p = 0.012), lateral periodic discharges on EEG (p = 0.034), and occurrence of major complications during hospitalization (p = 0.007). An SE duration of >100 h was clearly associated with a worse outcome (p < 0.001). In the multiple regression analysis, the only independent predictors of a poor outcome at discharge were an SE duration of >+100 hours (p = 0.001), a potentially fatal etiology (p = 0.001), and complications during hospitalization (p = 0.010). An SE duration of >100 hours retained its value as the optimal cutoff point for predicting poor outcomes at both 1 year (p = 0.037) and 4 years (p = 0.05). Other predictors of poor long-term outcomes were a potentially fatal etiology (p < 0.001) and EMSE score (p = 0.034) at 1 year, and progressive symptomatic etiology at 4 years (p = 0.025). SIGNIFICANCE: In patients with focal NCSE without consciousness impairment, a potentially fatal etiology and an SE duration of >100 h were associated with poor short-term and long-term outcomes.

Identificando puntos de mejoría en el manejo de la epilepsia en países en vías de desarrollo: experiencia de neurocooperación en Camerún / Identifying areas for improvement in epilepsy management in developing countries: An experience of neurocooperation in Cameroon

INTRODUCCIÓN: La epilepsia es una enfermedad prevalente en países en vías de desarrollo debido al mayor número de causas que pueden producirla, al menos duplicándose tanto incidencia como prevalencia en comparación con nuestro medio. Además, existe una gran estigmatización y los medios para su manejo son limitados. MATERIAL Y MÉTODOS: Estudio observacional descriptivo mediante la realización de un cuestionario a profesionales sanitarios de 3 hospitales de Camerún, interrogando sobre factores relacionados con el manejo de la epilepsia, en diciembre de 2016. Se presentan los datos como media o porcentaje. RESULTADOS: Participaron 38 profesionales sanitarios, de los cuales el 42,1% eran mujeres, con una edad media de 40,1 años (rango 22-62). Respecto a la causa de la enfermedad un 68,4% la considera psiquiátrica, 34,2% degenerativa, 28,9% hereditaria y 21,1% secundaria a una infección. En cuanto al manejo un 23,7% consideraba suficiente la anamnesis para llegar al diagnóstico. Solo un 60,5% consideraba la historia importante en el diagnóstico, 52,6% consideraba necesario un EEG, un 28,9% creía importantes las pruebas de laboratorio y un 13,2% la neuroimagen. Durante el embarazo solo un 36,8% considera importante asociar ácido fólico, solo el 65,8% cree que hay que mantener el tratamiento y solo un 39,5% creía recomendable la lactancia. Acerca del conocimiento de antiepilépticos, el número medio de fármacos conocido era de 2, siendo el más conocido el fenobarbital (81,6%) seguido de carbamacepina (55,3%) y ácido valproico (28,9%). CONCLUSIONES: La educación y la mejor información sobre la enfermedad, su diagnóstico y las opciones de manejo son necesarias en los profesionales sanitarios para optimizar el manejo y con ello la calidad de vida de los pacientes

INTRODUCTION: Epilepsy is especially prevalent in developing countries: incidence and prevalence rates are at least twice as high as in our setting. Epilepsy is also highly stigmatised, and few resources are available for its management. MATERIAL AND METHODS: We performed a descriptive observational study in December 2016, distributing a questionnaire on epilepsy management to healthcare professionals from 3 different hospitals in Cameroon. Data are presented as means or percentages. RESULTS: Thirty-eight healthcare providers participated in the survey; 42.1% were female and mean age was 40.1 years (range, 22-62). Regarding the causes of epilepsy, 68.4% considered it a psychiatric condition, 34.2% a degenerative disease, 28.9% a hereditary condition, and 21.1% secondary to infection. In terms of management, 23.7% considered that thorough clinical history is sufficient to establish a diagnosis. Only 60.5% considered the clinical interview to be important for diagnosis, 52.6% considered EEG to be necessary, and 28.9% considered laboratory analyses to be important. Only 13.2% mentioned neuroimaging. In the treatment of pregnant women, 36.8% recommended folic acid supplementation, 65.8% believed antiepileptic treatment should be maintained, and only 39.5% recommended breastfeeding. Concerning treatment, the participants knew a mean of 2 antiepileptic drugs: phenobarbital was the best known (81.6%), followed by carbamazepine (55.3%) and valproic acid (28.9%). CONCLUSIONS: There is a need among healthcare professionals for education and information on the disease, its diagnosis, and management options, in order to optimise management and consequently improve patients' quality of life

Seizures in the Emergency Department: Clinical and diagnostic data from a series of 153 patients. / Crisis epilépticas en urgencias: aspectos clínicos y diagnósticos de una serie de 153 pacientes.

INTRODUCTION: Seizures are a frequent reason for admission to emergency departments and require early, precise diagnosis and treatment. The objective of this study was to describe the clinical and prognostic characteristics of a series of patients with seizures attended at our hospital's emergency department. METHODS: We performed a retrospective, observational study of all patients with seizures who were admitted to our hospital's emergency department and attended by the on-call neurology service between February and August 2017. RESULTS: We included 153 patients, representing 9.9% of all neurological emergency department admissions. The median age was 58 years, 52.3% of patients were women, and 51% had history of epilepsy. Onset was focal in 82.4% of cases, and the most frequent aetiology was cerebrovascular disease (24.2%). Twelve patients (7.8%) developed status epilepticus, which was associated with higher scores on the ADAN scale (P<.001) and with history of refractory epilepsy (P=.002). The in-hospital mortality rate was 3.7%, and in-hospital mortality was associated with older age (P=.049) and status epilepticus (P=.018). Eighty percent of patients with no history of epilepsy were diagnosed with epilepsy at the emergency department; all started treatment. The kappa coefficient for epilepsy diagnosis in the emergency department compared to diagnosis after one year of follow-up by the epilepsy unit was .45 (diagnosis was modified in 20% of patients). CONCLUSIONS: Seizures are a frequent neurological emergency with potential complications and considerable morbidity and mortality rates. In patients with no known history of epilepsy, the condition may be diagnosed in the emergency department, but follow-up at specialised epilepsy units is recommended.

La gestión de la asistencia neurológica en tiempos de la pandemia de Covid-19 / Management of neurological care during the COVID-19 pandemic

INTRODUCCIÓN: La pandemia de Covid-19 ha supuesto la necesidad de tomar decisiones para mantener la asistencia neurológica, sin precedentes. En este artículo se analiza esa toma de decisiones operativas. Desarrollo: Los autores refieren las fórmulas empleadas como son la realización de un plan de reorganización funcional, estrategias para la hospitalización y urgencias, la realización de consultas telefónicas para el mantenimiento de la atención neurológica, la asistencia en un área externa al hospital para pacientes preferentes, las decisiones sobre exploraciones complementarias y tratamientos intrahospitalarios periódicos o implantar un teléfono para la priorización de crisis epilépticas. CONCLUSIÓN: A pesar de la situación de aislamiento, los servicios de neurología deben mantener la atención de sus pacientes a través de distintas fórmulas operativas, que como cualquier elemento de gestión, deberán evaluarse

INTRODUCTION: The COVID-19 epidemic has led to the need for unprecedented decisions to be made to maintain the provision of neurological care. This article addresses operational decision-making during the epidemic. Development: We report the measures taken, including the preparation of a functional reorganisation plan, strategies for hospitalisation and emergency management, the use of telephone consultations to maintain neurological care, provision of care at a unit outside the hospital for priority patients, decisions about complementary testing and periodic in-hospital treatments, and the use of a specific telephone service to prioritise patients with epileptic seizures. CONCLUSION: Despite the situation of confinement, neurology departments must continue to provide patient care through different means of operation. Like all elements of management, these must be evaluated

Specificity of electroclinical features in the diagnosis of ring chromosome 20.

BACKGROUND: Ring chromosome 20 (R20) syndrome is a chromosomal disorder characterized mainly by drug-resistant frontal lobe seizures, recurrent nonconvulsive status epilepticus (NCSE), and typical EEG features. The aim of this study was to investigate if this triad is common and specific to all patients with R20. METHODS: In this cross-sectional study (from 2000 to 2011), we selected patients who fulfilled at least two out of three criteria: drug-resistant frontal lobe seizures, recurrent NCSE, and characteristic electroencephalography (EEG) features. In all patients, diagnosis was based on karyotype analysis of at least 100 metaphases. RESULTS: We identified 36 patients who met at least two of the selected criteria: six patients (16.7%) with R20 and 30 (83.3%) without R20 (non-R20). All patients with R20 met all three criteria. Eleven (36.7%) patients without R20, however, also displayed the full triad. In 19 patients without R20 (63.3%), one of the three clinical features was missing: frontal lobe seizures were not resistant to antiepileptic drugs (AED) in four (13.3%), recurrent NCSE was missing in six (20%), and nine (30%) patients did not have typical EEG features. Based on this data, specificity was 63.3%, positive predictive value was 35.3%, and sensitivity and negative predictive values were 100%. Additionally, a review of all publications describing the R20 phenotype revealed that 81.98% of patients with R20 display the full electroclinical triad. CONCLUSIONS: In our study, all patients with R20 displayed the three electroclinical characteristics. This is in line with previous reports (presenting high sensitivity and negative predictive value). However, these features can also be observed in other epilepsies and are not specific to R20. Our findings suggest that in the presence of the full triad of symptoms, karyotype analysis focused on chromosome 20 should be conducted.

Sistema de visión global en laparoscopia / Global vision system in laparoscopy

Objetivo: La principal dificultad en la cirugía laparoscópica o robótica es la estrechez del campo de visión, restringido por el puerto de acceso del endoscopio. A ello se suma la dificultad en el manejo de los instrumentos, debida no solo al puerto de acceso, sino a la pérdida de la profundidad de campo y de la perspectiva por la ausencia de una iluminación natural. En este artículo describimos un sistema de visión global y explicamos la experiencia inicial en un modelo porcino. Material y métodos: El sistema de visión global consta de una serie de dispositivos intraabdominales, que aumentan el campo de visión y que ayudan a recuperar la perspectiva mediante la simulación de sombras naturales. Consta de una serie de cámaras de alta definición y de luces LED, que son introducidas y fijadas a la pared mediante imanes. La eficacia del sistema se ha evaluado en una varicocelectomía y en una nefrectomía. Resultado: Las diferentes cámaras intraabdominales ofrecen más puntos de visión intuitivos del área operatoria en comparación con el telescopio convencional y parece ser similar a la visión en cirugía abierta. Incluso se pueden alcanzar áreas inaccesibles al telescopio habitual. Las fuentes de luz adicionales crean sombras que aumentan la perspectiva del campo operatorio. Conclusión: Este sistema parece aumentar las posibilidades de la cirugía laparoscópica o robótica, ya que al ofrecer una visión instantánea de casi la totalidad del abdomen puede permitir realizar procedimientos más complejos, que hoy en día requieren una vía abierta

Objective: The main difficulty in laparoscopic or robot-assisted surgery is the narrow visual field, restricted by the endoscope's access port. This restriction is coupled with the difficulty of handling the instruments, which is due not only to the access port but also to the loss of depth of field and perspective due to the lack of natural lighting. In this article, we describe a global vision system and report on our initial experience in a porcine model. Material and methods: The global vision system consists of a series of intraabdominal devices, which increase the visual field and help recover perspective through the simulation of natural shadows. These devices are a series of high-definition cameras and LED lights, which are inserted and fixed to the wall using magnets. The system's efficacy was assessed in a varicocelectomy and nephrectomy.: Results The various intraabdominal cameras offer a greater number of intuitive points of view of the surgical field compared with the conventional telescope and appear to provide a similar view as that in open surgery. Areas previously inaccessible to the standard telescope can now be reached. The additional light sources create shadows that increase the perspective of the surgical field. Conclusion: This system appears to increase the possibilities for laparoscopic or robot-assisted surgery because it offers an instant view of almost the entire abdomen, enabling more complex procedures, which currently require an open pathway

CONCLUSION: This system appears to increase the possibilities for laparoscopic or robot-assisted surgery because it offers an instant view of almost the entire abdomen, enabling more complex procedures, which currently require an open pathway.
