Encefalopatías epilépticas de inicio en recién nacidos y lactantes / Epileptic encephalopathies of onset in neonates and infants

Resumen Recientemente la Liga Internacional contra la Epilepsia (ILAE) socializó la clasificación propuesta para síndromes epilépticos de inicio neonatal y hasta los primeros 2 años de edad, dividiéndolos en síndromes epilépticos autolimitados y las encefalopatías epilépticas y del desarrollo (DEEs). En esta revisión nos dedicaremos a las DEEs, definidas como trastornos donde existe deterioro del desarrollo relacionado tanto con la etiología subyacente independiente de la actividad epileptiforme como con la encefalopatía epiléptica. Estas incluyen en el período neonatal la encefalopatía epiléptica infantil temprana o síndrome de Ohtahara y la encefalopatía mioclónica temprana, ahora agrupadas bajo la denominación de encefalopatías epilépticas y del desarrollo infantil temprano (EIDEE). El síndrome de espamos epilépticos infantiles, la epilepsia de la infancia con crisis migratorias y el síndrome de Dravet forman parte de las encefalopatías de inicio en el lactante. La importancia del reconocimiento temprano de las encefalopatías epilépticas radica no solo en el control de las crisis epilépticas, sino en detener el deterioro intentando cambiar el curso de la enfermedad. Es fundamental conocer la etiología evitando medicamentos que puedan exacerbar las crisis y empeorar el curso, aplicando medicina de precisión así como identificando pacientes candidatos a cirugía temprana de epilepsia.

Abstract The International League Against Epilepsy (ILAE) recently socialized the proposed classification for epileptic syndromes of neonatal onset and up to the first 2 years of age, dividing them into self-limited epileptic syndromes and epileptic and developmental encephalopathies (DEEs). In this review we will focus on DEEs, defined as disorders in which there is developmental impairment related to both the underlying aetiology independent of epileptiform activity and epileptic encephalopathy. These include early infantile epileptic encephalopathy or Ohtahara syndrome and early myoclonic encephalopathy in the neonatal period, now grouped under the name of epileptic and early childhood developmental encephalopathies (EIDEE). Infantile epileptic spasms syndrome, childhood epilepsy with migratory crises and Dravet syndrome are part of the infant-onset encephalopathies. The importance of early recognition of epileptic encephalopathies lies not only in the control of epileptic seizures, but also in stopping deterioration by trying to change the course of the disease. It is essential to know the etiology, avoiding medications that can exacerbate seizures and worsen the course, applying precision m edicine as well as identifying candidate patients for early epilepsy surgery.

Calidad de vida en pacientes con epilepsia y crisis no epilépticas psicógenas: una revisión sistemática / Quality of life in patients with epilepsy and psychogenic nonepileptic seizures: a systematic review

Resumen Se han revisado artículos que estudiaron la calidad de vida en las personas con crisis no epilépticas psicógenas (CNEP) y crisis epilépticas. Se siguió la guía PRISMA y, previo a la búsqueda, se realizó un protocolo publicado en PROSPERO. Se incluyeron estudios aleatorizados y no aleatorizados, de tipo cuantitativo o mixtos, de corte transversal o longitudinal, escritos en lengua inglesa o española publicados hasta el año 2020, y cuyos participantes fueran mayores de 16 años. Luego de filtrar los resultados según los criterios de selección, se incluyeron 11 artículos y una tesis doctoral cuyos años de publicación datan de 1998 a 2020. En su mayoría, se informaba que las personas con CNEP tenían menor calidad de vida, asociadas a presencia de psicopatología, así como también a la toma de medicación antiepiléptica, factores sociodemográficos y relacionados con las crisis (frecuencia, severidad y duración de enfermedad), funcionamiento familiar, trauma y somatización.

Abstract Psychogenic non epileptic seizures (PNES) are disruptive changes in behaviour, thought, or emotion that resemble an epileptic seizure, but without paroxysmal neuronal discharge detectable by electroencephalography (EEG), and are not caused by another medical condition. On the other hand, epileptic seizures (ES) are defined as clinical events that reflect the presence of hypersynchronous discharges of neurons located in the cerebral cortex, which have the particularity of starting and ending abruptly. The diagnosis of epilepsy is made when an epileptic seizure was experienced and there is a risk of having another. The objective of this paper is to present the results of a systematic review of articles that have studied quality of life in people with PNES and ES. This review has been performed following the PRISMA guide (Preferred Reporting Items for Systematic reviews and Meta-Analyses). Prior to the beginning of the search, a protocol was carried out and it is published for consultation in the International prospective register of systematic reviews (PROSPERO). The review includes randomized and non-randomized, quantitative or mixed, cross-sectional or longitudinal studies, published in English or Spanish until 2020. In addition, participants had to be over 16 years old. PNES diagnosis must have been confirmed by video-electroencephalography (VEEG) or a similar procedure-which is considered the gold standard for the diagnosis of PNES.

Síndrome de Sturge-Weber: revisión de la literatura / Sturge-Weber syndrome: literature review

El síndrome de Sturge-Weber es un trastorno neurocutáneo, congénito, esporádico e infrecuente que afecta aproximadamente a 1 de cada 20 000 a 50 0000 nacidos vivos y que se relaciona con una mutación genética activadora somática en GNAQ. Clínicamente se caracteriza por la presencia de una mácula en vino de Oporto en la piel de territorio trigeminal, angiomatosis leptomeníngea y glaucoma. Puede asociarse a diferentes manifestaciones clínicas, de las cuales las crisis epilépticas representan la manifestación neurológica más frecuente que se asocia a un deterioro cognitivo importante en estos pacientes. En el presente artículo se realiza una revisión descriptiva de la literatura sobre los aspectos etiológicos, fisiopatológicos, de clasificación, clínicos, diagnósticos y del tratamiento del síndrome de Sturge-Weber.

Sturge-Weber syndrome is a rare, sporadic, congenital neurocutaneous disorder affecting approximately 1 in 20,000 to 50,000 live births that is associated with a somatic activating gene mutation in GNAQ. Clinically it is characterized by the presence of a port wine stain on the skin of trigeminal territory, leptomeningeal angiomatosis and glaucoma. It can be associated with different clinical manifestations, of which the epileptic seizures represents the most frequent neurological manifestation associated with significant cognitive impairment in these patients. This article makes a descriptive review of the literature on the etiological, pathophysiological, classification, clinical, diagnostic and treatment aspects of Sturge-Weber syndrome.

Eventos no epilépticos psicógenos: El desafío constante de su diagnóstico y tratamiento / Psychogenic non epileptic events: The constant challenge of its diagnosis and treatment

Resumen Los eventos no epilépticos psicógenos (ENEP) son episodios paroxísticos descritos como cambios conductuales, alteraciones sensorio-sensitivas, o manifestaciones motoras que se asemejan a las crisis epilépticas pero sin mostrar actividad epileptiforme subyacente, no son producidos deliberadamente por el individuo, y responden a mecanismos multifactoriales de índole biopsicosocial. La información epidemiológica es limitada debido a la naturaleza heterogénea de la población afectada, así como a la escasa accesibilidad al videoelectroencefalograma (vEEG) necesario para su diagnóstico. En este contexto, es necesaria la convergencia de dos elementos importantes: historia clínica detallada (características clínicas sugerentes de ENEP e identificación de los factores asociados) y la ausencia de cambios electroencefalográficos en el vEEG durante el episodio. La evaluación psicológica provee información adicional relevante para la corroboración diagnóstica y para su manejo. El diagnóstico debe realizarse de manera oportuna, para evitar complicaciones en su evolución y tratamiento. Es vital una actitud positiva y alentadora hacia el/la paciente al momento de comunicarle su diagnóstico, así como la coordinación entre el neurólogo tratante y los profesionales de salud mental involucrados en el manejo y seguimiento del caso. La psicoterapia cognitiva conductual, asociada a psicofármacoterapia -cuando pertinente-, constituyen el tratamiento más eficaz de estos pacientes. Existen limitados estudios en Latinoamérica sobre aspectos epidemiológicos y clínico-evolutivos de pacientes con ENEP, por lo que más investigación y publicaciones respecto a esta problemática son indispensables dado su impacto sobre la calidad de vida de los pacientes y sobre el costo de su manejo en los sistemas de salud.

Summary Psychogenic Non-Epileptic Events (PNEE) are paroxysmal episodes described as behavioral changes, sensory- sensitive disturbances, or motor manifestations that resemble epileptic seizures without showing underlying epileptiform activity, are not deliberately produced by the individual, and respond to multifactorial biopsychosocial mechanisms. Epidemiological information is limited due to the heterogeneous nature of the affected population, and to the limited accessibility to the video electroencephalogram (vEEG) necessary for its diagnosis. In such context, the convergence of two important elements is necessary: a detailed clinical history (clinical characteristics suggestive of PNEE, and identification of the associated factors), and the absence of electroencephalographic "ictal" changes in the vEEG. A psychological evaluation provides additional information, relevant for the diagnostic corroboration and management. The diagnosis must be made in a timely manner, to avoid complications in its evolution and treatment. A positive and encouraging attitude to the patient is vital when informing him/her of the diagnosis, as it also is the coordination between the treating neurologist and mental health professionals involved in the management and monitoring of the case. Cognitive behavioral psychotherapy, associated with psychopharmacotherapy -when needed-- constitute the most effective treatment approach for these patients. There are limited studies on the current epidemiological and clinical evolution of patients with PNEE in Latin America, and additional research regarding this problem is much needed, given its impact on the quality of life of the patients and on the cost of its management in the health care systems.

Imitador De Ictus Debido A Trombosis Venosa Cerebral / Stroke Mimic Due To Cerebral Venous Thrombosis

RESUMEN Introducción: Un imitador de ictus es toda aquella patología no vascular que se presenta como un ictus isquémico agudo. La presentación clínica, factores epidemiológicos, el tiempo de inicio, la distribución vascular y la disponibilidad de pruebas de imagen, son factores que ayudan a diferenciarlos. Caso clínico: Presentamos un caso, de una mujer de la tercera edad que fue llevada a urgencias por hemiparesia izquierda de cinco horas de evolución. La evolución clínica y las pruebas complementarias permitieron excluir el diagnóstico de ictus isquémico agudo. La semiología fue explicada por una parálisis de Todd prolongada que se comportó como imitador de ictus en la fase aguda y las crisis epilépticas se produjeron en el contexto de una trombosis venosa cerebral. Comentarios: Los imitadores de ictus, al contrario del ictus isquémico agudo, ocurren en pacientes más jóvenes, tienen menos factores de riesgo vascular, menor puntuación de NIHSS, menos afasia y disfagia. Las principales causas son crisis epilépticas y síncopes. Deben considerarse también migrañas, neoplasias, alteraciones tóxicas o metabólicas, encefalopatías y trastornos funcionales. Realizar un estudio neurovascular completo y pruebas dirigidas nos permitirán el diagnóstico.

ABSTRACT Introduction: A stroke mimic is any non-vascular pathology that presents as an acute ischemic stroke. The clinical presentation, the epidemiological factors, the time to onset, vascular distribution and the availability of imaging tests are factors that help to differentiate them. Case report: We present a case, of a woman of the third age who was taken to the emergency department due to a five-hour history of left hemiparesis. The clinical evolution and the supplementary tests allowed to exclude the diagnosis of acute ischemic stroke. The semiology was explained by a prolonged Todd's palsy that behaved as a stroke mimic at the acute phase and the seizures occurred in the context of a cerebral venous thrombosis. Comments: Stroke mimics, in contrast to acute ischemic stroke, occur in younger patients, have fewer vascular risk factors, lower NIHSS score, less aphasia and dysphagia. The main causes are seizures and syncope. Migraines, neoplasms, toxic or metabolic alterations, encephalopathies and functional disorders should also be considered. To perform a complete neurovascular study and directed tests will allow us to make the diagnosis.

Pseudoseizures with urinary incontinence in a child with Neuromyelitis optica: a rare association

Background: Paroxysmal non epileptic events or pseudoseizures are common seizure mimics in children. But occasionally PNES events can present or coexist along with organic neurological disorders complicating the clinical scenario posing great challenges for diagnostic and therapeutic implications. Unusual symptomatology in PNES like frothing, tongue bite or urinary incontinence can be seen in PNES. Here, we present a rare case of pseudoseizures with urinary incontinence in a child with Neuromyelitis optica which posed a challenge for diagnosis and proper management with a favourable clinical outcome. A 14 years old girl who was known diagnosed case of Neuromyelitis optica on treatment with oral steroids presented with a history of repeated attacks of involuntary movements affecting all four limbs preceded by a feeling of fear and pain and these events were associated with urinary incontinence. Electroencephalogram and magnetic resonance imaging were performed on the patient. Ictal video EEG confirmed the diagnosis of pseudoseizures. Neuropsychological evaluation was performed which revealed multiple psychological stressors. Repeated counseling sessions and psychotherapy provided significant improvement in the form of remission of pseudoseizures.

El equipo multidisciplinario en la aplicación clinica de la dieta cetogénica / Multidisciplinary teamwork in the clinical application of the ketogenic diet

La dieta cetogénica se considera un tratamiento eficaz y bien tolerado para la epilepsia refractaria. Nuestro trabajo suministra información práctica sobre el uso de la dieta cetogénica, realizando una revisión acerca de las indicaciones clásicas y las nuevas que permiten ampliar el uso de la misma. Detallamos cómo implementar la dieta, los controles médicos en el seguimiento y la forma de actuar en situaciones especiales, tales como la anestesia o la enfermedad aguda. Se enfatiza la i mportancia del trabajo de los profesionales de las distintas especialidades y la familia como equipo, detallando los roles que ocupa cada uno en este interesante pero laborioso tratamiento.

The ketogenic diet is an established, effective and well-tolerated treatment in refractory epilepsy. This paper provides practical information on the administration of ketogenic diet. It goes over the standardized protocols and the new ones that allow to broaden the scope regarding the clinical management of the ketogenic diet. It addresses issues such as the implementation, counseling and follow-up as well as the application and how to proceed in special situations such as anesthesia or acute illness. Finally, the aim of this paper is to highlight the relevance of the multidisciplinary teamwork and the family support throughout this laborious but interesting treatment.

Epileptic Seizure Due to Disulfiram Treatment / 가정의학회지

Disulfiram has been used for the treatment of alcohol dependence for nearly 65 years and is approved by the Food and Drug Administration. It causes negative reinforcement by accumulating toxic acetaldehyde due to irreversible inhibition of aldehyde dehydrogenase. Disulfiram has very few side effects when taken without alcohol. Epileptic seizure induction is a rare side effect in therapeutic doses, and its mechanism is unknown. We present a patient with a single epileptic seizure which was thought to be due to disulfiram used in the treatment of alcohol dependence. We did not find it ethical to administer disulfiram again because the patient discontinued alcohol use and was afraid of epileptic seizures.

Modelos conceptuales y explicativos sobre las crisis no epilépticas psicógenas (CNEP) / Conceptual and explanatory models of Psychogenic Non-Epileptic Seizures (PNES)

Las Crisis No Epilépticas Psicógenas (CNEP) son episodios similares a las crisis epilépticas, pero a diferencia de éstas, no son causadas por la actividad eléctrica anómala del cerebro. Se diagnostican una vez descartadas otras causas fisiopatológicas. El objetivo de este artículo es presentar la conceptualización actual de este fenómeno. Para ello, en primer lugar realizaremos una historización del fenómeno, relacionándolo con la categoría de histeria; segundo lugar, describiremos las clasificaciones propuestas por las distintas ediciones del Manual Diagnóstico y Estadístico de los trastornos mentales, destacando su última versión (DSM-V); finalmente, introduciremos las corrientes actuales que explican este fenómeno, las cuales toman el rol de la disociación como categoría central que explica tanto el diagnóstico así como los objetivos de tratamiento para las CNEP. La categoría disociación es la clave para entender la dirección en la que se está avanzando en psicopatalogía, la búsqueda de los procesos psicológicos específicos subyacentes para entender el mecanismo que lleva a producir tanto las CNEP como otros cuadros de psicopatológicos.

Psychogenic Non Epileptic Crises (CNEP) have been a challenge to diagnostic and explanation for the mental health field. They are diagnosed after discard out other pathophysiological causes of the crisis. They are similar to epileptic seizures, but unlike these, they are not caused by electrical activity in the brain. In order to present the current conceptualization of this phenomenon, we propose in first place to describe its historical development, second, the current classification of the Diagnostic and Statistical Manual (DSM-V), third, to introduce the present currents that explain this phenomenon by taking the role of dissociation as a central category that explains the diagnosis and the treatment objectives for the CNEP. The dissociation category is the key to understand the direction in which progress is being made in psychopathology, the search for the specific underlying psychological processes to understand the mechanism that leads to producing both the CNEP and other psychopathological frames.

Tremor de cabeça idiopático em cães - relato de dois casos / Idiopathic head tremor in dogs - two case reports

Tremor de cabeça idiopático é uma forma de discinesia paroxística reconhecida como hereditária e associada a determinadas raças, sendo relatado, sobretudo, em Buldogue Inglês, Dobermann Pinscher e Boxer. Conhecido também como head bobbing ou tremor de cabeça episódico, os cães acometidos apresentam crises caracterizadas por tremores limitados à região de cabeça, de direção horizontal, vertical ou ambos, sendo geralmente relacionados a um evento desencadeante. Foram atendidos, no Hospital Veterinário da UFMS, dois caninos da raça Buldogue Inglês (um macho de um ano e uma fêmea de sete meses) com histórico de tremores episódicos restritos à região de cabeça. Exames físicos e neurológicos completos foram realizados, não sendo constatada qualquer alteração. Com base na raça, no histórico, na ausência de outros sinais clínicos e na exclusão de outras causas de tremores, foi dado o diagnóstico de head bobbing. Tal enfermidade caracteriza-se por tremores restritos à região de cabeça, associados a uma condição genética benigna. Não é considerada uma forma de convulsão, uma vez que o animal permanece alerta e responsivo aos estímulos ambientais, os tremores podem ser interrompidos por distrações ou qualquer interação com o ambiente, não sendo responsivos à terapia com anticonvulsivantes. De acordo com a revisão de literatura realizada, estes são os primeiros casos diagnosticados e relatados no Brasil.(AU)

Idiopathic head tremor is a form of paroxysmal dyskinesia recognized as hereditary or associated with certain races, being reported in English bulldogs, doberman pinschers, and boxers. Also known as head bobbing or episodic head tremor, the affected dogs present with seizures characterized by tremors limited to head region, horizontal direction, vertical or both and are usually related to a triggering event. Two dogs of the English bulldog breed (a male of 1 year and a female of 7 months) with a history of episodic tremors restricted to the head region were seen at the UFMS Veterinary Hospital. Complete physical and neurological examinations were performed, and no alterations were found. Based on race, history, absence of other clinical signs and exclusion of other causes of tremors, the diagnosis of head bobbing was performed. Such a disease is characterized by tremors restricted to the head region, associated with a benign genetic condition. It is not considered a form of seizure, since the animal remains alert and responsive to environmental stimuli, the tremors can be interrupted by distractions or any interaction with the environment, being not responsive to anticonvulsant therapy. According to the literature review, these are the first cases diagnosed and reported in Brazil.(AU)

Paroxysmal non-epileptic motor phenomena in newborns / 国际儿科学杂志

A variety of paroxysmal motor phenomena often occur in newborns,including physiological events(immaturity of the central nervous system) and pathological events(epileptic and non-epileptic).The clini cian should be able to properly identify and diagnose the paroxysmal motor phenomena with various etiologies.There are some clinical features that may help clinicians with the diferentation among physiological and pathological,epileptic and non-epileptic events.However,VEEG monitoring is still the gold standard for differentiating the paroxysmal motor phenomena of epileptic and non-epileptic seizures,which can help to further clarify the etiology.In this paper,the clinical features,underlying pathophysiological mechanisms and differential diagnoses of non-epileptic paroxysmal motors in newborns were reviewed.

Eventos Críticos en el Recién Nacido / Newborn Critical Events

El periodo neonatal corresponde a una etapa en el desarrollo en el que las convulsiones constituyen la expresión clínica de disfunción del sistema nervioso central. Estas se manifiestan por una alteración en la función neurológica que puede ser motora, autonómica, de la conducta o una combinación de ellas. Dado que en este periodo el desarrollo anatómico, bioquímico y fisiológico, presentan características muy diferentes al desarrollo del niño mayor, las convulsiones pueden ser muy difíciles de identificar y pueden confundirse con eventos clínicos paroxísticos no epilépticos del recién nacido. Lo anterior se explica porque las convulsiones presentan patrones poco organizados, suelen no ser bien definidas y el registro electroencefalográfico es diferente al del niño mayor. En su mayoría las CN son secundarias a una etiología específica, por lo que es indispensable encontrar la causa lo cual se encuentra fuertemente relacionado al pronóstico. También es necesario diferenciar los eventos no epilépticos, para un óptimo manejo. Palabras clave: convulsiones neonatales, newborn, seizures, non epileptic seizures, disfunción cerebral.

The neonatal period corresponds to a developmental stage in which seizures are the clinical expression of central nervous system dysfunction. These are manifested by a change in neurological function that can be motor, autonomic, behavior or a combination of them.Given that in this period the anatomical, biochemical and physiological development present with very different characteristics to those of the older child, seizures can be very difficult to identify, and can be confused with paroxysmal non epileptic clinical events of the newborn. This is explains why seizures have little organized patterns are often not well defined and the Electroencephalographic record is different from that found in the older child. For the most part, neonatal seizures are secondary to a specific etiology, so it is essential to find the cause, which is strongly related to the prognosis. It is also necessary to differentiate non-epileptic events, for optimal handling. Key words: Neonatal seizures, neonatal, non epileptic seizures, brain dysfunction.

Caracterização da epilepsia com início após os 60 anos de idade / Characterization of epilepsy with onset after 60 years of age

Resumo Introdução: Apesar da elevada incidência, a epilepsia no idoso ainda exibe peculiaridades pouco estudadas. A apresentação clínica na maioria das vezes é atípica e os achados nos exames complementares pouco ajudam no diagnóstico. Existem poucas publicações caracterizando esse grupo de indivíduos. Objetivo: Descrever as características de pacientes com epilepsia iniciada após os 60 anos de idade. Método: Foi desenvolvido estudo descritivo de série de casos, onde foram avaliados, consecutivamente, 50 pacientes com diagnóstico de epilepsia iniciada após os 60 anos de idade, atendidos no ambulatório de epilepsia do Hospital da Restauração (Recife-PE). Resultados: Dos 50 pacientes incluídos no estudo, a idade média foi de 75,3 (±13) anos, sendo que 30 (60,0%) eram do sexo feminino e 20 (40,0%) do sexo masculino. A idade média da primeira crise foi de 72,5 (±11,5) anos. Predominaram as crises epilépticas focais (83,8%). A ocorrência de estado de mal epiléptico foi baixa nesse grupo (4,0%). A epilepsia sintomática foi a mais frequente, tendo como etiologia vascular a causa mais encontrada (43,0%). A medicação mais utilizada foi a carbamazepina, e as crises apresentaram uma boa resposta terapêutica com monoterapia em dose baixa. O eletroencefalograma apresentou resultado normal em número elevado de casos (50,0%) e a neuroimagem na maioria das vezes (83,0%) apresentou achados inespecíficos. Conclusão: A epilepsia no idoso é predominantemente focal e sintomática, apresenta baixa ocorrência de estado de mal epiléptico e boa resposta terapêutica. O eletroencefalograma e a neuroimagem, na maioria das vezes, são inespecíficos.

Abstract Introduction: Despite its high incidence, the characteristics of epilepsy in elderly patients have not yet been widely studied. The clinical presentation of the disease is mostly atypical and findings from complementary examinations provide little help with diagnosis. Few reports have characterized this group of individuals. Objective: To describe the characteristics of patients with epilepsy with onset after 60 years of age. Method: A descriptive study of a case series was designed. For this purpose, 50 patients diagnosed with epilepsy with onset after 60 years of age, treated at the outpatient epilepsy clinic of the Hospital da Restauração (Recife-PE), were consecutively assessed. Results: The 50 patients included in the study had an average age of 75.3 (±13) years, 30 (60.0%) were female and 20 (40.0%) were male. The average age at the first seizure episode was 72.5 (±11.5) years. Focal epilepsy seizures were the most predominant (83.8%). The occurrence of status epilepticus was low in this group (4.0%). Symptomatic epilepsy was the most frequent type, and most of the causes were of vascular etiology (43.0%). Carbamazepine was most commonly used for treatment, and the patients responded well to low-dose monotherapy. Electroencephalograms displayed normal results in many cases (50.0%), and neuroimaging showed nonspecific findings for most individuals (83.0%). Conclusion: Epilepsy in elderly patients is predominantly focal and symptomatic, with a low occurrence of status epilepticus and good therapeutic response. The encephalogram and neuroimaging results are frequently nonspecific.

Comparison of MMPI Profile Patterns between Patients with Epileptic Seizures and Psychogenic Non-Epileptic Seizures

BACKGROUND: Psychogenic non epileptic seizures (PNES) are characterized by repeated seizures that are typically caused by stress and psychologic problems such as anxiety and depression. This contrasts with epileptic seizures (ES), which are transient and caused by irregular excitement of nerve cells. PNES can be found in patients with ES, but due to their differing etiologies, it is important to determine the psychologic characteristics that differentiate PNES from ES. METHODS: This study identified psychopathologic and personality traits in 137 patients with PNES (n=7, 49.3% female) or ES (n=0, 35.7% female) using MMPI. The diagnosis was based on a medical history of seizures and the clinical examination in patients who visited the epilepsy clinic. Statistical analyses for comparing MMPI differences between the two groups were conducted using the t-test, chi-square test, and analysis of covariance. RESULTS: We analyzed the frequency of individuals who exhibited a T score of ≥5 on the MMPI, and the results indicated that there were significantly more patients in the PNES group than in the ES group who had elevated scores on the hypochondriasis (Hs) scale and hysteria (Hy) scale. The mean scores of Hs, Hy, paranoia scale and schizophrenia scale were significantly higher in the PNES group than in the ES group. CONCLUSIONS: These results suggest that patients with PNES have greater psychologic problems than ES patients. Differences in MMPI profile patterns between patients with PNES and ES may be helpful in tailoring appropriate therapeutic interventions for the two groups.

Mortality predictors of epilepsy and epileptic seizures among hospitalized elderly / Preditores de mortalidade de epilepsia e crises epilépticas entre idosos hospitalizados

Epilepsy and epileptic seizures are common brain disorders in the elderly and are associated with increased mortality that may be ascribed to the underlying disease or epilepsy-related causes. Objective To describe mortality predictors of epilepsy and epileptic seizures in elderly inpatients.Method Retrospective analysis was performed on hospitalized elderly who had epilepsy or epileptic seizures, from January 2009 to December 2010. One hundred and twenty patients were enrolled.Results The most common etiology was ischemic stroke (37%), followed by neoplasias (13%), hemorrhagic stroke (12%), dementias (11.4%) and metabolic disturbances (5.5%). In a univariate analysis, disease duration (p = 0.04), status epilepticus (p < 0.001) and metabolic etiology (p = 0.005) were associated with mortality. However after adjustment by logistic regression, only status epilepticus remained an independent predictor of death (odds ratio = 13; 95%CI = 2.3 to 72; p = 0.004).Conclusion In this study status epilepticus was an independent risk factor for death during hospitalization.

Epilepsia e crises epilépticas são transtornos cerebrais comuns em idosos e estão associadas com uma taxa de mortalidade elevada que pode ser atribuída à etiologia ou a causas relacionadas à epilepsia. Objetivo Descrever preditores de mortalidade em pacientes idosos internados com epilepsia e crise epiléptica.Método Estudo retrospectivo, envolvendo idosos hospitalizados, de 60 anos ou mais, que foram admitidos de janeiro de 2009 a dezembro de 2010 por terem apresentado epilepsia e crises epilépticas durante a hospitalização. Cento e vinte pacientes foram incluídos no estudo.Resultados A etiologia mais comum foi o acidente vascular cerebral isquêmico (37%), seguido por neoplasias (13%), acidente vascular cerebral hemorrágico (12%), demências (11,4%) e distúrbios metabólicos (5,5%). Na análise univariada, duração da doença (p = 0,04), estado de mal epiléptico (p < 0,001) e etiologia metabólica (p = 0,005) estiveram associados com mortalidade. Entretanto, após ajuste por regressão logística, apenas estado de mal epiléptico permaneceu como preditor independente de morte (odds ratio = 13; IC95% = 2,3 a 72; p = 0,004).Conclusão Neste estudo, estado de mal epiléptico foi um fator independente de risco para morte durante hospitalização.

Etiological prevalence of epilepsy and epileptic seizures in hospitalized elderly in a Brazilian tertiary center – Salvador - Brazil / Prevalência etiológica de epilepsia e crises epilépticas em idosos hospitalizados em centro terciário – Salvador – Brasil

Epilepsy in the elderly has high incidence and prevalence and is often underecognized. Objective To describe etiological prevalence of epilepsy and epileptic seizures in elderly inpatients. Methods Retrospective analysis was performed on elderly patients who had epilepsy or epileptic seizures during hospitalization, from January 2009 to December 2010. One hundred and twenty patients were enrolled. They were divided into two age subgroups (median 75 years) with the purpose to compare etiologies. Results The most common etiology was ischemic stroke (36.7%), followed by neoplasias (13.3%), hemorrhagic stroke (11.7%), dementias (11.4%) and metabolic disturbances (5.5%). The analysis of etiological association showed that ischemic stroke was predominant in the younger subgroup (45% vs 30%), and dementias in the older one (18.9% vs 3.8%), but with no statistical significance (p = 0.23). Conclusion This study suggests that epilepsy and epileptic seizures in the elderly inpatients have etiological association with stroke, neoplasias and dementias. .

Métodos Estudo retrospectivo, envolvendo idosos hospitalizados, de 60 anos ou mais, que foram admitidos de janeiro de 2009 a dezembro de 2010 por terem apresentado epilepsia e crises epilépticas durante a hospitalização. Cento e vinte pacientes foram incluídos no estudo. Os pacientes foram divididos em dois subgrupos de idade (mediana 75 anos), com o propósito de comparar etiologias. Resultados A etiologia mais comum foi o acidente vascular cerebral isquêmico (36,7%), seguido por neoplasias (13,3%), acidente vascular cerebral hemorrágico (11,7%), demências (11,4%) e distúrbios metabólicos (5,5%). A análise da associação etiológica mostrou que o acidente vascular cerebral isquêmico predominou no subgrupo mais jovem (45% vs 30%), e as demências no subgrupo mais velho (18,9% vs 3,8%), contudo essa diferença não evidenciou significância estatística (p = 0,23). Conclusão Este estudo sugere que epilepsia e crise epiléptica em idosos internados têm associação etiológica com acidente vascular cerebral, neoplasias e demências. .

Psychogenic non-epileptic seizures and psychoanalytical treatment: results / Crises não epilépticas psicogênicas e tratamento psicanalítico: resultados.

Background: the occurrence of psychogenic non-epileptic seizures (PNES) is estimated to be between 2 to 33 cases in every 100,000 inhabitants. The number of patients with PNES reaches 19% of those treated as epileptics. Patients with PNES are treated as if they had intractable epilepsy, with unsatisfactory results even after medication treatment is used to its maximum. The aim of this study is to present the effects of individual psychoanalytical treatment in patients with PNES, assessing its impact in the evolution of the clinical picture and its association with sex, time of disease, social, psychological and professional harm, as well as going through with treatment. Methods: The case base was composed of 37 patients with PNES. The diagnosis was reached with video-EEG monitoring. Psychoanalytical treatment was carried out through 12 months of weekly sessions timed for around 50-minutes each, in a total of 48 individual sessions. Results: This study found a high rate of success in the treatment of PNES patients. 29.7% (n=11) of patients had cessation or cure of symptoms and 51.4% (n=19) had a decrease in the number of episodes. There is an association between cessation or decrease in the number of episodes and sex (p<0.01), religion (p<0.01) and concluding treatment (p<0.01). Conclusion: Individual psychoanalytical treatment applied to patients with PNES is considered effective and can be an essential form of assistance for the reduction or cessation of episodes. .

Introdução: estima-se que o número de casos de pacientes com crises não epilépticas psicogênicas (CNEP) seja de 2 a 33 por 100 mil habitantes. O índice de CNEP corresponde ainda a, aproximadamente, 19% dos pacientes tratados como epilépticos. Os pacientes com CNEP são tratados como portadores de epilepsia refratária, chegando ao limite máximo do tratamento medicamentoso e sem a obtenção de resultados satisfatórios. Objetivo: relatar os efeitos do tratamento psicanalítico individual em pacientes com CNEP de forma a avaliar a evolução do quadro clínico de CNEP e verificar sua associação com gênero, tempo de crise, prejuízos sociais, afetivos e profissionais, bem como término do tratamento. Métodos: a casuística foi composta por 37 pacientes com diagnóstico de CNEP feito por meio da monitoração por vídeo-EEG. Foram realizadas sessões de tratamento psicanalítico: atendimento clínico individual com frequência semanal, com duração aproximada de 50 minutos e duração total de 48 sessões em 12 meses. Resultados: este estudo constatou elevado índice de sucesso no tratamento dos pacientes com CNEP: 29,7% (n = 11) de cessação/cura dos sintomas e 51,4% (n = 19) de redução das crises convulsivas. Foi constatada associação entre cessar ou reduzir as crises e gênero (p<0,01), religião (p<0,01) e término do tratamento (p<0,01). Conclusão: este estudo apontou eficácia do tratamento psicanalítico individual realizado com pacientes com CNEP, podendo ser considerada uma forma de assistência essencial para que haja decréscimo ou cessação das crises. .

Antiepileptic drugs patterns in elderly inpatients in a Brazilian tertiary center, Salvador, Brazil / Uso de drogas antiepilépticas em idosos internados em centro terciário, Salvador, Brasil

Epilepsy is very prevalent among elderly inpatients and treatment is far from ideal. Objective To analyze prescribing patterns of antiepileptic drugs (AEDs) for hospitalized elderly with epilepsy, their relations with comorbidities and comedications. Method We assessed prescription regimen of elderly patients that were under AED use for treatment of epileptic seizures, during hospitalization. One hundred and nine patients were enrolled. AED regimen was categorized into two groups: Group 1 defined as appropriate (carbamazepine, oxcarbazepine, valproic acid, gabapentin, clobazan and lamotrigine) and Group 2 as inappropriate (phenytoin and phenobarbital). Results We found 73.4% of patients used inappropriate AEDs (p<0.001). Monotherapy was prescribed for 71.6% of patients. The most common comorbidity was hypertension. Potentially proconvulsant drugs as comedications were used for nearly half of patients. Conclusion Inappropriate AED therapy was commonly prescribed regimen for elderly inpatients. Some recommendations are discussed for a better care of elderly inpatients with epilepsy. .

Epilepsia é frequente entre idosos hospitalizados e o tratamento costuma ser aquém do ideal. Objetivo Analisar os padrões de prescrição de drogas antiepilépticas para idosos hospitalizados com epilepsia, bem como sua relação com comorbidades e comedicações. Método Revisamos os prontuários de pacientes idosos internados com diagnóstico de epilepsia e que estavam em uso de droga antiepiléptica (DAE) durante o período de hospitalização. Cento e nove pacientes foram incluídos no estudo. O regime de DAE foi categorizado em dois grupos: Grupo 1, definido como apropriado (carbamazepina, oxcarbazepina, ácido valpróico, gabapentina, clobazam e lamotrigina) e Grupo 2, como inapropriado (fenitoína e fenobarbital). Resultados 73,4% dos pacientes usaram DAE inapropriadas (p<0,001). Regime de monoterapia foi usado por 71,6% dos pacientes. Hipertensão arterial foi a comorbidade mais frequente. Medicações concomitantes potencialmente proconvulsivantes foram usadas por quase metade desta população. Conclusão Regime de droga antiepiléptica inapropriada foi o mais utilizado em pacientes idosos internados. São discutidas algumas recomendações para melhor cuidado ao paciente idoso hospitalizado com epilepsia. .

Quadriceps Tendon Rupture due to Postepileptic Convulsion

We present a case of quadriceps tendon (QT) rupture. QT ruptures can occur in all ages. The cause is mostly traumatic in origin. Spontaneous ruptures that are thought to result from predisposing conditions are rare. Post-convulsion QT ruptures lacking traumas in their history can be overlooked in clinical examinations. This should be born in mind by the attending physician, as early diagnosis and treatment of the condition can lead to satisfactory outcomes.
