EPITRANS. Quality assessment of the epilepsy transition process.

OBJECTIVE: To analyze the differences in clinical management during the epilepsy transition process from pediatric to adult care and to determine the quality of life and degree of satisfaction of patients and caregivers during the transition. METHODS: This is a longitudinal study including patients with epilepsy transferred from pediatric to adult epilepsy care between 2013 and 2017. Patients had a minimum follow-up of 3 years before the transition visit and at least 3 years consulting in the adults section. Clinical characteristics were retrieved from the medical chart. Quality of life and satisfaction questionnaires were administered by online access to patients and caregivers at the end of the adult follow-up period. RESULTS: 99 patients (50.5 % women, mean transition age 16.5 ± 1 years old) were included. Before the transition visit, 90 % of patients received a transition discussion and 88 % had a formal clinical report. In the pediatric period, patients were visited more frequently, had more EEGs and genetic studies, and were seen by the same neuropediatrician (P<0.05). In the adult period, patients underwent a larger number of prolonged video EEGs and were prescribed polytherapy more often (P<0.05). Quality of life remained steady during the entire transition, but satisfaction with the care received was significantly higher during the pediatric period. CONCLUSIONS: Significant differences were seen in epilepsy care during transition from pediatric to adult management, and this had an impact on the degree of satisfaction reported by patients and caregivers. Our results provide evidence of the potential value of development and early implementation of a protocolled transition program.

Implications of starting antiepileptic treatment prior to electroencephalography in first epileptic seizures.

INTRODUCTION: This study aimed to determine whether the administration of antiepileptic drugs (AED) alters the likelihood of detecting epileptiform abnormalities in electroencephalographies (EEG) performed early after a first epileptic seizure. METHODS: We performed a retrospective, observational study including patients with a first seizure attended at our centre's emergency department between July 2014 and November 2019. We collected clinical data, as well as technical data on the acquisition and interpretation of the EEG performed within the first 72 hours after the seizure, and the factors related with seizure recurrence. RESULTS: We recruited 155 patients with a mean (SD) age of 48.6 (22.5) years; 61.3% were men. Regarding seizure type, 51% presented tonic-clonic seizures of unknown onset and 12% presented focal to bilateral tonic-clonic seizures. Thirty-nine patients (25.2%) received AED treatment before the EEG was performed: 33 received a non-benzodiazepine AED and 6 received a benzodiazepine. Epileptiform abnormalities were observed in 29.7% of patients. Previous administration of AEDs was not significantly associated with the probability of detecting interictal epileptiform abnormalities (P = .25) or with the risk of recurrence within 6 months (P = .63). CONCLUSIONS: Administration of AEDs before an early EEG following a first seizure does not decrease the likelihood of detecting epileptiform abnormalities. These findings suggest that starting AED treatment immediately in patients with a high risk of early recurrence does not imply a reduction in the diagnostic accuracy of the test.

Epileptic seizures in the emergency room: clinical and electroencephalographic findings associated with brain perfusion patterns on computed tomography.

BACKGROUND: Diagnosis of epileptic seizures, particularly regarding status epilepticus (SE), may be challenging in an emergency room setting. The aim of the study was to study the diagnostic yield of perfusion computed tomography (pCT) in patients with single epileptic seizures and SE. METHODS: We retrospectively reviewed the records of patients who followed an acute ischemic stroke pathway during a 9-month period and who were finally diagnosed with a single epileptic seizure or SE. Perfusion maps were visually analyzed for the presence of hyperperfusion and hypoperfusion. Clinical data, EEG patterns, and neuroimaging findings were compared. RESULTS: We included 47 patients: 20 (42.5%) with SE and 27 (57.5%) with single epileptic seizure. Of 18 patients who showed hyperperfusion on pCT, 12 were ultimately diagnosed with SE and eight had EEG findings compatible with an SE pattern. Focal hyperperfusion on pCT had a sensitivity of 60% (95% CI 36.4-80.2) and a specificity of 77.8% (95% CI 57.2-90.6) for predicting a final diagnosis of SE. The presence of cerebral cortical and thalamic hyperperfusion had a high specificity for predicting SE presence. Of note, 96% of patients without hyperperfusion on pCT did not show an SE pattern on early EEG. CONCLUSIONS: In acute settings, detection by visual analysis of focal cerebral cortical hyperperfusion on pCT in patients with epileptic seizures, especially if accompanied by the highly specific feature of thalamic hyperperfusion, is suggestive of a diagnosis of SE and requires clinical and EEG confirmation. The absence of focal hyperperfusion makes a diagnosis of SE unlikely.

Overnight switch from levetiracetam to brivaracetam. Safety and tolerability.

Brivaracetam is a newer antiseizure medication than levetiracetam. It has a more selective action on the synaptic vesicle glycoprotein 2A binding site, and it seems to provide a more favorable neuropsychiatric profile. The aim of this study was to assess the safety and tolerability of an overnight switch from levetiracetam to brivaracetam. This was a retrospective descriptive study including patients with epilepsy treated with levetiracetam, who switched due to inefficacy or previous adverse events (AEs). In total, forty-one patients were included (mean age 40.9 ± 17.8 years, women 48.8%). Focal epilepsy represented 75.6% (n = 31) of patients (structural cause [n = 25], unknown cause [n = 6]). Four patients had idiopathic generalized epilepsy, two had developmental and epileptic encephalopathy and four patients were unclassified. The reason to start brivaracetam was inefficacy in 53.7% (n = 22), AEs in 65.9% (25/27 neuropsychiatric) and both in 19.5% (n = 8). Brivaracetam-related AEs were reported in 24.4%. Neuropsychological AEs associated with the previous use of levetiracetam improved in 76% of patients. Treatment was discontinued in 19.5% patients. Patients' reported seizure frequency improved, worsened and remained stable in 26.8%, 12.2%, and 61.0% of the cases, respectively. An overnight switching to brivaracetam is safe and well tolerated. This treatment can improve levetiracetam-related neuropsychiatric AEs.

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.

Thirty-nine patients (25.2%) received AED treatment before the EEG was performed: 33 received a non-benzodiazepine AED and 6 received a benzodiazepine. Epileptiform abnormalities were observed in 29.7% of patients. Previous administration of AEDs was not significantly associated with the probability of detecting interictal epileptiform abnormalities (P=.25) or with the risk of recurrence within 6 months (P=.63). CONCLUSIONS: Administration of AEDs before an early EEG following a first seizure does not decrease the likelihood of detecting epileptiform abnormalities. These findings suggest that starting AED treatment immediately in patients with a high risk of early recurrence does not imply a reduction in the diagnostic accuracy of the test.

[Quality of life in adult patients with idiopathic generalised epilepsy. The EPILAK study]. / Calidad de vida en pacientes adultos con epilepsia generalizada idiopática. Estudio EPILAK.

INTRODUCTION: Quality of life (QoL) is an important aspect in the treatment of patients with epilepsy. AIM: To analyse the QoL using the Quality of Life in Epilepsy Inventory-10 (QOLIE-10) in adults with idiopathic generalised epilepsy and to study factors associated with a worse QoL. PATIENTS AND METHODS: A cross-sectional, multicentre, observational study conducted by 141 neurologists in all the autonomous communities of Spain. Each researcher analysed the QOLIE-10 of two males and two females over 18 years of age with idiopathic generalised epilepsy seen consecutively in public or private practice. The results were standardised: 0 was the worst QoL and 100 was the best. RESULTS: A total of 546 patients were analysed. Women: 51.1% (n = 279). Mean age: 36 ± 15.3 years old (18-87). Childhood absence seizures: 7.5% (n = 41); juvenile absence seizures: 9.2% (n = 50); juvenile myoclonic seizures: 29.8% (n = 163); only tonic-clonic seizures: 53.5% (n = 292). Monotherapy: 63.2% (n = 345). Seizure-free in the last year: 53.1% (n = 290). Psychiatric comorbidity: anxiety: 28.4% (n = 155); depression: 14.1% (n = 77); attention deficit: 10.1% (n = 55). Employment status: in active employment: 47.2% (n = 258); student: 20% (n = 109); housewife/husband: 7.3% (n = 40); pensioner: 10.2% (n = 56); unemployed: 14.3% (n = 78). Marital status: married or in a relationship: 49.1% (n = 268); single: 43.7% (n = 239). Mean score on the QOLIE-10: 71.4 ± 19.1. Being female (p = 0.006), greater frequency of seizures (p < 0.001), polytherapy (p < 0.001), psychiatric comorbidity (p < 0.001) and unemployment (p < 0.001) were significantly associated with a worse QoL. CONCLUSIONS: The QoL of patients with idiopathic/genetic generalised epilepsy is affected by poor seizure control, psychiatric comorbidity and unemployment, and women are more affected than men.

How soon should urgent EEG be performed following a first epileptic seizure?

PURPOSE: Patients with a first unprovoked epileptic seizure are often seen in emergency services. Electroencephalography (EEG) is indicated for diagnosing epilepsy, but the optimal time to perform this test has not been defined. This study aimed to determine the time interval following a seizure within which EEG has the greatest diagnostic yield. METHODS: We conducted a retrospective study of all adult patients with a first unprovoked seizure who had undergone emergency EEG (July 2014-December 2019). Data collection included demographics, seizure type, time interval to EEG study, EEG pattern identified, and the prescription after emergency assessment. An optimal cut-off point for time to EEG was obtained, and an adjusted regression model was performed to establish associations with the presence of epileptiform abnormalities. RESULTS: A total of 170 patients were included (mean age: 50.7 years, 40.6% women). Epileptiform discharges were identified in 34.1% of recordings, nonepileptiform abnormalities in 46.5%, and normal findings in 19.4%. A lower latency from seizure to EEG was associated with a higher probability of finding epileptiform discharges (median: 12.7 in the epileptiform EEGs vs. 20 h in the nonepileptiform EEGs, p < 0.001). The time interval associated with the highest probability of detecting an epileptiform EEG pattern was within the first 16 h after seizure onset: 52.1% of recordings performed before the 16-h cut-off showed these abnormal patterns compared with 20.2% performed after (p < 0.001). These findings were not related to the presence of an epileptogenic lesion in neuroimaging or to other clinical variables. The finding of epileptiform abnormalities was followed by a greater prescription of antiseizure drugs (96.4% vs. 66% in nonepileptiform patterns, p < 0.001). CONCLUSION: The diagnostic yield of EEG following a first unprovoked epileptic seizure is highest when this test is performed within the first 16 h after onset of the event.

TITLE: Leucoencefalopatia multifocal progresiva y disfuncion inmune no especificada.

The ADAN scale: a proposed scale for pre-hospital use to identify status epilepticus.

BACKGROUND AND PURPOSE: The prognosis of status epilepticus (SE) depends on the time between onset and the diagnosis and start of treatment. Our aim was to design a scale with predictive value for pre-hospital diagnosis of SE. METHODS: This was a retrospective study of 292 patients who attended the emergency department for an epileptic seizure. A total of 49 patients fulfilled the criteria for SE. We recorded the patients' history and clinical features. Variables independently associated with SE were combined to design a clinical scale. The performance of the scale was evaluated in a validation dataset of 197 patients. RESULTS: A total of 50.3% of the patients were male and the mean age was 55.9 years. The following features were more prevalent in patients with SE: abnormal speech (79.6% vs. 18.9%, P < 0.001), eye deviation (69.4% vs. 14.0%, P < 0.001), automatism (22.4% vs. 6.3%, P < 0.001), hemiparesis (24.5% vs. 10.9%, P = 0.011), state of stupor/coma (46.9% vs. 4.2%, P < 0.001) and number of pre-hospital seizures, i.e. two (34.7% vs. 4.5%, P < 0.001) or more than two (51.0% vs. 0.4%, P < 0.001). Based on these findings, we designed a scale that scored 1 point each for presence of abnormal speech, eye deviation, automatism and two seizures, and 2 points for more than two seizures. The predictive capacity of the scale for identifying SE in the validation dataset was 98.7% (95% confidence interval, 97.3%-100%) and 85.4% of patients with a score >1 had SE. CONCLUSIONS: A score >1 on the ADAN scale is a robust predictor of the diagnosis of SE in patients who experience an epileptic seizure. This scale may be a useful tool for clinical use and warrants further investigation.

[Social cognition and cognitive functions in patients with epilepsy treated with eslicarbazepine acetate]. / Cognicion social y funciones cognitivas en pacientes con epilepsia tratados con acetato de eslicarbacepina.

INTRODUCTION: Epilepsy is accompanied by cognitive disorders, frequently aggravated by the use of antiepileptic drugs, which can affect social empathy. AIM: To analyse the impact of treatment with eslicarbazepine acetate (ESL) on social cognition and prefrontal cognitive functions in adults with focal epilepsy. PATIENTS AND METHODS: We conducted a prospective single-centre study with patients aged between 18 and 65 years with focal seizures treated with ESL. The patients were evaluated in their baseline visit and at six months after starting ESL treatment by means of tasks designed for theory of mind, executive and attentional functions, auditory-verbal memory, quality of life, and anxiety and depression. RESULTS: Forty-one patients were treated with ESL, and 30 completed the follow-up. A significant improvement was observed in the theory of mind tasks. In the analysis stratified by sex, the men showed greater improvement. A cognitive improvement was observed in the Wisconsin Card Sorting Test, Symbol Digit, Backward Digit Span and Stroop tests. No differences were found in the Quality of Life in Epilepsy-31 Inventory or in the Hospital Anxiety and Depression Scale. These results were independent of the reduction in the number of seizures and the ESL dosage. CONCLUSION: Treatment with ESL could improve some aspects of theory of mind in patients with epilepsy, especially in men and independently of the control of seizures, with no changes in quality of life, anxiety or depression.

La epilepsia se acompaña de alteraciones cognitivas, frecuentemente agravadas por el uso de farmacos antiepilepticos, que pueden afectar a la empatia social. Objetivo. Analizar el impacto del tratamiento con acetato de eslicarbacepina (ESL) en la cognicion social y las funciones cognitivas prefrontales en adultos con epilepsia focal. Pacientes y metodos. Estudio prospectivo y unicentrico realizado en pacientes de 18 a 65 años con crisis focales, tratados con ESL. Los pacientes fueron evaluados en la visita basal y a los seis meses tras iniciar ESL mediante tareas para la teoria de la mente, funciones ejecutivas y atencionales, memoria audioverbal, calidad de vida, y ansiedad y depresion. Resultados. Cuarenta y un pacientes fueron tratados con ESL y 30 completaron el seguimiento. Se observo una mejoria significativa en las tareas de teoria de la mente. En el analisis estratificado por sexo, los hombres mejoraron mas. Se observo una mejoria cognitiva en las pruebas Wisconsin Card Sorting Test, Symbol Digit, Backward Digit Span y test de Stroop. No hubo diferencias en el cuestionario Quality of Life in Epilepsy-31 Inventory ni en la escala de depresion y ansiedad hospitalaria (HADS). Estos resultados fueron independientes de la reduccion del numero de crisis y de la dosis de ESL. Conclusion. El tratamiento con ESL podria mejorar algunos aspectos de la teoria de la mente en pacientes con epilepsia, especialmente en hombres e independientemente del control de las crisis, sin cambios en la calidad de vida, ansiedad o depresion.

Outcome of cancer-related seizures in patients treated with lacosamide.

OBJECTIVES: Lacosamide is an antiepileptic drug (AED), which has proven to be effective to control seizures, including acute conditions such as status epilepticus. The aim of this study is to describe the clinical experience with lacosamide in neuro-oncological patients. MATERIALS AND METHODS: Multicenter retrospective study in patients with cancer-related seizures, who received lacosamide as an add-on therapy. RESULTS: Forty-eight patients with benign and malignant tumors, including primary brain tumors, lymphomas, systemic cancer with central nervous system involvement, or paraneoplastic encephalitis, were included. Lacosamide was effective in the control of chronic seizures in patients with either benign or malignant tumors. The success rate was greater in malignant tumors, and drug-resistant epilepsies were more likely associated with benign tumors. Adverse events occurred in nearly 70% of patients, particularly in acute conditions and associated with the concomitant use of radio-/chemotherapy. Lacosamide-related adverse events were more likely somnolence and dizziness, which usually resolved after dose adjustment. After starting lacosamide, nearly half of the patients discontinued one of the baseline AEDs and decreased or discontinued dexamethasone. Fifteen patients with status epilepticus were treated with intravenous lacosamide, and 73% of them had their condition resolved without serious drug-related adverse events. CONCLUSION: Lacosamide is an AED to consider in cases of cancer-related seizures. Lacosamide pharmacodynamics and pharmacokinetics allow the achievement of responder rates over 50% with no serious adverse effects, amelioration of side effects from other AEDs or radio-/chemotherapy, and no significant drug interactions. Furthermore, the intravenous formulation shows clear benefits in acute conditions such as status epilepticus.

Estudio descriptivo retrospectivo de las IC realizadas a Neurología durante un año (período: mayo del 2013-abril del 2014) en nuestro centro. Resultados. Se incluyó a 472 pacientes (edad media 62,1, varones 56,8%). Previamente, el 24,4% había sido valorado por un neurólogo. Mediana de 18 días de ingreso y el 19,7% de ellos fueron derivados desde otro hospital. Servicios más demandantes: Medicina Intensiva 20,1%, Medicina Interna 14,4% y Cardiología 9,1%. Motivos IC: ictus 26,9%, epilepsia 20,6% y cuadros confusionales 7,6%. El 41,9% fue valorado por un neurólogo de guardia. Objetivo IC: diagnóstico 56,3% y tratamiento 28,2%. En el 69,5% de los casos fueron necesarias pruebas complementarias. En el 18,9% se ajustó el tratamiento y se introdujo al menos un medicamento en 27,3%. El 62,1% de las IC se resolvieron con una valoración. El 11% precisó revaluación y un 4,9% fue trasladado a Neurología. El 16,9% delos pacientes fallecieron durante ingreso (de ellos, en el 37,5% el motivo fue el diagnóstico de muerte encefálica). El 45,6% fue derivado a Neurología al alta y consultó en Urgencias un 6,1% por motivos neurológicos en los 6 meses posteriores al alta. Conclusiones. Las IC facilitan el diagnóstico y el manejo de pacientes con enfermedades neurológicas, posiblemente disminuyendo las consultas de estos pacientes en Urgencias. En un hospital terciario, es destacable la labor del neurólogo de guardia y la importancia del diagnóstico de muerte encefálica (AU)

Introduction. In-hospital consultations (IHC) are essential in clinical practice in tertiary hospitals. The aim of this study is to analyse the impact of neurological IHCs. Patients and method. One-year retrospective descriptive study of neurological IHCs conducted from May 2013 to April 2014 at our tertiary hospital. Results. A total of 472 patients were included (mean age, 62.1 years; male patients, 56.8%) and 24.4% had previously been evaluated by a neurologist. Patients were hospitalised a median of 18 days and 19.7% had been referred by another hospital. The departments requesting the most in-hospital consultations were intensive care (20.1%), internal medicine (14.4%), and cardiology (9.1%). Reasons for requesting an IHC were stroke (26.9%), epilepsy (20.6%), and confusional states (7.6%). An on-call neurologist evaluated 41.9% of the patients. The purpose of the IHC was to provide a diagnosis in 56.3% and treatment in 28.2% of the cases; 69.5% of the patients required additional tests. Treatment was adjusted in 18.9% of patients and additional drugs were administered to 27.3%. While 62.1% of cases required no additional IHCs, 11% required further assessment, and 4.9% were transferred to the neurology department. Of the patient total, 16.9% died during hospitalisation (in 37.5%, the purpose of the consultation was to certify brain death); 45.6% were referred to the neurology department at discharge and 6.1% visited the emergency department due to neurological impairment within 6 months of discharge. Conclusions. IHCs facilitate diagnosis and management of patients with neurological diseases, which may help reduce the number of visits to the emergency department. On-call neurologists are essential in tertiary hospitals, and they are frequently asked to diagnose brain death (AU)

Trombosis de la vena ovárica: casuística en 5 años y revisión de la literatura / Ovarian vein thrombosis: Casuistry over 5 years and literature review

La trombosis de la vena ovárica (TVO) es una complicación infrecuente pero grave en el posparto. Afecta entre el 0,02-0,2% del total de gestaciones, 0,02-0,18% de los partos vaginales, y entre el 1-2% de las cesáreas. Hasta en el 90% de los casos afecta a la vena ovárica derecha, y puede extenderse hasta la vena cava inferior originando complicaciones muy graves. El diagnóstico y tratamiento tempranos son fundamentales. Presentamos los casos de trombosis de la vena ovárica ocurridos en el puerperio durante los últimos 5 años en el Complejo Hospitalario de Pontevedra, y una revisión de la bibliografía existente

The ovarian vein thrombosis (OVT) is a rare but serious complication in the postpartum. It affects between 0.02% and 0.2% of all pregnancies, from 0.02% to 0.18% of vaginal deliveries and between 1% and 2% of caesarean sections. In up to 90% of cases it affects the right ovarian vein and it may extend as far as the inferior vena cava, causing serious complications. Early diagnosis and treatment are crucial. We present the cases of ovarian vein thrombosis having occurred in the postpartum period during the last 5 years in the Complejo Hospitalario de Pontevedra and a review of existing literature

[Classification of idiopathic generalised epilepsies in patients over 16 years of age]. / Clasificacion de las epilepsias generalizadas idiopaticas en mayores de 16 años.

INTRODUCTION: Idiopathic generalised epilepsies (IGE) are a set of electroclinical syndromes with different phenotypes. Our aim is to analyse those phenotypes in patients over 16 years of age. PATIENTS AND METHODS: We conducted a retrospective analysis of a series of patients with IGE. They were classified as childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), epilepsy with tonic-clonic seizures only (TCSE), epilepsy with eyelid myoclonias and absences (EMA) and pure photogenic epilepsy (PE). RESULTS: We included 308 patients, the majority females (56.8%), in our study. JME was the most prevalent (40.9%), followed by TCSE (30%), JAE (10%), EMA (8.7%), CAE (7.7%) and PE (1.6%). The types of seizures presented by the most patients were tonic-clonic (89.6%), myoclonic (45.4%), absence (31.4%), reflex seizures (13.3%), eyelid myoclonias (12.6%), non-epileptic psychogenic seizures (3.6%) and status epilepticus (1.9%). They all had generalised spike-and-wave discharges in the electroencephalogram (EEG). 19.2% presented asymmetrical discharges and 28.2% showed a photoparoxysmal response. We observed differences between syndromes in polytherapy (p < 0.0001), withdrawal of therapy (p = 0.01) and being seizure-free beyond the age of 50 (p = 0.004). CONCLUSIONS: JME was the most frequent. Generalised tonic-clonic seizures were the type of seizures presented by the most patients, followed by myoclonic, absent and reflex seizures. The EEG showed a photoparoxysmal response in over a quarter of the patients, and one in five displayed asymmetrical anomalies. Differences were observed according to the syndrome in polytherapy, persistence of seizures and withdrawal of treatment.

Las epilepsias generalizadas idiopaticas (EGI) son un conjunto de sindromes electroclinicos con distintos fenotipos. Nuestro objetivo es analizar dichos fenotipos en pacientes mayores de 16 años. Pacientes y metodos. Analizamos retrospectivamente una serie de pacientes con EGI. Los clasificamos en epilepsia de ausencias infantil (EAI), epilepsia de ausencias juvenil (EAJ), epilepsia mioclonica juvenil (EMJ), epilepsia con crisis tonicoclonicas solo (ECTC), epilepsia con ausencias y mioclonias palpebrales (EAM) y epilepsia fotogenica pura (EF). Resultados. Incluimos 308 pacientes, mayoritariamente mujeres (56,8%). La EMJ fue mas prevalente (40,9%), seguida de la ECTC (30%), la EAJ (10%), la EAM (8,7%), la EAI (7,7%) y la EF (1,6%). Los tipos de crisis que presentaron mas pacientes fueron las tonicoclonicas (89,6%), las mioclonicas (45,4%), las ausencias (31,4%), las crisis reflejas (13,3%), las mioclonias palpebrales (12,6%), las crisis psicogenas no epilepticas (3,6%) y el estado epileptico (1,9%). Todos tenian descargas punta-onda generalizada en el electroencefalograma (EEG). El 19,2% presento descargas asimetricas y el 28,2%, respuesta fotoparoxistica. Observamos diferencias entre sindromes en politerapia (p < 0,0001), retirada de tratamiento (p = 0,01) y estar libres de crisis por encima de los 50 años (p = 0,004). Conclusiones. La EMJ fue la EGI mas frecuente. Las crisis tonicoclonicas generalizadas fueron el tipo de crisis que presentaron mas pacientes, seguidas de las mioclonicas, las ausencias y las crisis reflejas. El EEG mostro en mas de una cuarta parte de los pacientes una respuesta fotoparoxistica, y en uno de cada cinco, anomalias asimetricas. Se observaron diferencias segun el sindrome en politerapia, persistencia de crisis y retirada de tratamiento.

Rufinamide in children and adults in routine clinical practice.

OBJECTIVE: To explore the long-term effectiveness of rufinamide in managing Lennox-Gastaut Syndrome (LGS), other epileptic encephalopathies, and intractable focal epilepsies in adults and children in routine clinical practice. METHODS: A multicentre, retrospective chart review of patients prescribed adjunctive rufinamide at seven Spanish epilepsy centres, with assessments at six and 12 months. RESULTS: We evaluated data from 58 patients (40 male, age range 7-57 years), 25 of whom were diagnosed with LGS, 12 with other epileptic encephalopathies and 21 of whom were diagnosed with focal epilepsies, mainly frontal lobe. The mean daily rufinamide dose was 32.0 mg/kg (range 12.5-66.7 mg/kg) in children and 24.7 mg/kg (range 5.0-47.0 mg/kg) in adults, and the most commonly used concomitant antiepileptic drugs were levetiracetam and valproate. Rufinamide was discontinued in 25 patients (43.1%) during the 1-year follow-up, and the most common reason was lack of effectiveness (n = 12, 20.7% of total). The frequency of generalized tonic-clonic seizures was significantly reduced from baseline at 6 and 12 months (P = 0.001), both in patients with generalized epilepsies and in patients with focal epilepsies. Significant seizure frequency reduction from baseline was observed at 12 months (P = 0.01) for tonic/atonic seizures and at 6 months (P = 0.001) for focal seizures. Side effects were reported in 21 patients (36.2%): nausea, vomiting and weight loss were most frequent. CONCLUSIONS: Rufinamide was well tolerated and was effective in reducing frequency of generalized tonic-clonic, tonic/atonic and focal seizures in both children and adults with severe refractory epilepsies, primarily LGS.

Descriptive analysis of neurological in-hospital consultations in a tertiary hospital. / Análisis descriptivo de las consultas intrahospitalarias dirigidas a Neurología en un hospital terciario.

INTRODUCTION: In-hospital consultations (IHC) are essential in clinical practice in tertiary hospitals. The aim of this study is to analyse the impact of neurological IHCs. PATIENTS AND METHOD: One-year retrospective descriptive study of neurological IHCs conducted from May 2013 to April 2014 at our tertiary hospital. RESULTS: A total of 472 patients were included (mean age, 62.1 years; male patients, 56.8%) and 24.4% had previously been evaluated by a neurologist. Patients were hospitalised a median of 18 days and 19.7% had been referred by another hospital. The departments requesting the most in-hospital consultations were intensive care (20.1%), internal medicine (14.4%), and cardiology (9.1%). Reasons for requesting an IHC were stroke (26.9%), epilepsy (20.6%), and confusional states (7.6%). An on-call neurologist evaluated 41.9% of the patients. The purpose of the IHC was to provide a diagnosis in 56.3% and treatment in 28.2% of the cases; 69.5% of the patients required additional tests. Treatment was adjusted in 18.9% of patients and additional drugs were administered to 27.3%. While 62.1% of cases required no additional IHCs, 11% required further assessment, and 4.9% were transferred to the neurology department. Of the patient total, 16.9% died during hospitalisation (in 37.5%, the purpose of the consultation was to certify brain death); 45.6% were referred to the neurology department at discharge and 6.1% visited the emergency department due to neurological impairment within 6 months of discharge. CONCLUSIONS: IHCs facilitate diagnosis and management of patients with neurological diseases, which may help reduce the number of visits to the emergency department. On-call neurologists are essential in tertiary hospitals, and they are frequently asked to diagnose brain death.

A new clinical score for the prognosis of status epilepticus in adults.

BACKGROUND AND PURPOSE: The severity of status epilepticus (SE) has an important impact in clinical outcomes. The Status Epilepticus Severity Score (STESS) is a score for predicting mortality in SE at admission. The baseline modified Rankin Scale (mRS) might be a prognostic factor for assessing the short-tem outcomes of SE. Therefore, our aim was to evaluate the effectiveness of mRS and whether its addition to the STESS improves the prediction of mortality. METHODS: Consecutive patients with SE and aged >16 years were recruited during 3 years. Receiver operating characteristic curves and a logistic regression model were developed to estimate the scores of the new score, designated as modified STESS (mSTESS), and it was subsequently compared with the STESS. RESULTS: In all, 136 patients were included. Mean age was 62.01 ± 17.62 (19-95) years, and 54% were male. The capacity of the STESS to predict mortality was 74.3% (95% confidence interval 63.8%-81.8%), whilst the capacity of the mRS to predict mortality was 65.2% (95% confidence interval 54.2%-76.2%). The logistic regression model and receiver operating characteristic curves enabled the classification of mRS as follows: 0, mRS = 0; 1, mRS = 1-3; and 2, mRS > 3. These values, when added to the other items of the STESS, resulted in the mSTESS with scores between 0 and 8 points. The capacity of the mSTESS to predict mortality was 80.1%. An mSTESS > 4 established an overall accuracy of 81.8% for predicting mortality, which was considerably higher than the overall accuracy of STESS ≥ 3 (59.6%). CONCLUSIONS: The baseline mRS was associated with high mortality risk. It is proposed to use mSTESS to improve the prediction of mortality risk in SE.
