Predictive factors for successful vagus nerve stimulation in patients with refractory epilepsy: real-life insights from a multicenter study

Vagus nerve stimulation (VNS) therapy is an established treatment for patients with drug-resistant epilepsy that reduces seizure frequency by at least 50% in approximately half of patients; however, the characteristics of the patients with the best response have not yet been identified. Thus, it is important to identify the profile of patients who would have the best response to guide early indications and better patient selection.

A terapia com estimulação do nervo vago (ENV) é um tratamento estabelecido para pacientes com epilepsia resistente a medicamentos que reduz a frequência de crises em pelo menos 50% em aproximadamente metade dos pacientes; entretanto, as características dos pacientes com melhor resposta ainda não foram identificadas. Assim, é importante identificar o perfil de pacientes que teriam melhor resposta para orientar indicações precoces e melhor seleção de pacientes.

Contracepção em situações especiais / Contraception in special situations

A decisão de escolha do método contraceptivo em situações clínicas especiais é desafiadora tanto para médicos quanto para pacientes. Em parte, isso se deve às contraindicações reais que alguns contraceptivos apresentam. Porém, há uma estreita relação com a falta de conhecimento e medo de muitos profissionais em prescrever métodos que, na realidade, são seguros. A má escolha do método contraceptivo para pacientes portadoras de condições específicas pode levar a diversos desfechos ruins, como piora da condição de base, ocorrência de eventos adversos indesejáveis e preveníveis e ocorrência de gravidez de alto risco indesejada. Dessa forma, foi realizada uma revisão na literatura com o objetivo de auxiliar profissionais médicos na decisão contraceptiva de pacientes portadoras de doenças reumatológicas e musculoesqueléticas, epilepsia, esclerose múltipla, transtornos alimentares, anemia falciforme e obesidade, e que já foram submetidas a cirurgia bariátrica.(AU)

The decision to choose the contraceptive method in special clinical situations is challenging for both physicians and patients. In part, this is due to the real contraindications that some contraceptives present. However, there is a close relationship with the lack of knowledge and fear of many professionals in prescribing methods that are actually safe. The poor choice of contraceptive method in patients with specific conditions can lead to several bad outcomes, such as worsening of the baseline condition, occurrence of undesirable and preventable adverse events and occurrence of an unwanted high-risk pregnancy. Thus, a literature review was carried out in order to assist medical professionals in the contraceptive decision of patients with rheumatological and musculoskeletal diseases, epilepsy, multiple sclerosis, eating disorders, sickle cell anemia, obesity and who have already undergone bariatric surgery.(AU)

Neurocisticercosis y epilepsia en un hospital universitario de Popayán, Colombia: una serie de casos / Neurocysticercosis and epilepsy in a university hospital in Popayán, Colombia: A case series

RESUMEN INTRODUCCIÓN: La neurocisticercosis es una infección del sistema nervioso central causada por el estadio larvario del cestodo Taenia solium, y se estima que puede ocasionar hasta 30% de los casos de epilepsia en los países donde esta parasitosis es endémica. El objetivo de este estudio fue determinar la frecuencia de pacientes que presentaron epilepsia como secuela de neurocisticercosis en un hospital universitario en Popayán. MATERIALES Y MÉTODOS: Se realizó un estudio retrospectivo con todos los pacientes con diagnóstico de neurocisticercosis que ingresaron al Hospital Universitario San José entre enero 2014 y diciembre 2018 que cumplieron los criterios de inclusión. RESULTADOS: Se encontraron 50 pacientes, de estos, 40 (80%) reingresaron, encontrándose que 37 (74%) presentaron epilepsia como secuela. Las edades más afectadas fueron la de 41 a 60 años; 48 (96%) provenían del departamento del Cauca en especial de Mercaderes, y 33 (66%) de área rural. El síndrome convulsivo fue la manifestación clínica de ingreso más frecuente. La TAC fue la técnica de imagen de elección. CONCLUSIÓN: El departamento del Cauca se considera como una de las áreas endémicas para neurocisticercosis en Colombia, y la epilepsia secundaria es un secuela común.

ABSTRACT INTRODUCTION: Neurocysticercosis is an infection of the central nervous system caused by the larval stage of the cestode Taenia solium, it has been estimated to produce up to 30% of the cases in countries where this parasitosis is endemic. The objective of this study was to determine the frequency of patients who presented epilepsy as a sequel of neurocysticercosis in a university hospital in Popayán. MATERIALS AND METHODS: A retrospective study was conducted with all patients with a diagnosis of neurocysticercosis who were admitted to the Hospital Universitario San José between January 2014 and December 2018 who met the inclusion criteria. RESULTS: We found 50 patients, 40 (80%) of which were readmitted and 37 (74%) presented epilepsy as sequela. The most affected age-group was 41 to 60 years; 48 (96%) were from the department of Cauca, especially Mercaderes, and 33 (66%) from rural areas. Convulsive syndrome was the most frequent clinical manifestation on admission. CT was the imaging technique of choice. CONCLUSION: The department of Cauca is considered as an endemic area for neurocysticercosis, and secondary epilepsy was a common consequence.

Deficiencia del transportador de glucosa tipo 1: aspectos clínicos, diagnóstico y terapéutica / Glucose transporter type 1 deficiency syndrome: clinical aspects, diagnosis, and treatment

El síndrome de deficiencia del transportador de glucosa tipo 1 es una enfermedad de causa genética, que involucra el gen SLC2A1. En general, se presenta durante los primeros años de vida con retraso en la adquisición de pautas madurativas, epilepsia farmacorresistente y desórdenes del movimiento. La clínica y la disminución de glucosa en líquido cefalorraquídeo permiten sospechar el diagnóstico, el cual debe ser confirmado mediante el estudio molecular del gen SLC2A1. Debido a que se trata de una enfermedad poco frecuente y de expresión clínica variable, el diagnóstico precoz suele representar un desafío para los equipos de salud. Este es importante, ya que la implementación de la terapia cetogénica logra controlar las manifestaciones clínicas y mejora el pronóstico a largo plazo. Presentamos una revisión sobre el déficit del transportador de glucosa tipo 1, que abarca sus características clínicas, bioquímicas, moleculares y terapéuticas.

Glucose transporter type 1 deficiency with a typical onset is a genetic disorder associated with the SLC2A1 gene. Usually appears during the first years of life with severe developmental delay, drugresistant epilepsy, and movement disorders. Diagnosis is suspected based on clinical manifestations and a low glucose level in cerebrospinal fluid, and should be confirmed by the molecular genetic study of the SLC2A1 gene. As it is a rare disease with variable clinical expression, early diagnosis is often challenging for the healthcare team. Nevertheless, this is important because early implementation of ketogenic therapy will lead to control of the clinical manifestations and a better long-term prognosis. Here we review the glucose transporter type 1 deficiency syndrome focusing on its clinical, biochemical, molecular, and therapeutic characteristics.

Implicações odontológicas do consumo da dieta cetogênica para tratamento da epilepsia / Dental implications of the consumption of a ketogenic diet for the treatment of epilepsy

A epilepsia configura-se como sendo uma patologia crónica oriunda de manifestação elétrica cerebral de caráter anormal, que ocasiona repercussões neurológicas. O tratamento da epilepsia emprega a administração medicamentosa e também pode utilizar o recurso da dieta cetogénica. Sabe-se que o recurso da utilização da dieta cetogênica para enfrentamento da epilepsia promove repercussões a nível da saúde bucal dos enfermos em tratamento. O objetivo deste artigo foi evidenciar como o emprego da dieta cetogênica na terapia utilizada para enfrentamento da epilepsia pode influenciar na saúde bucal dos indivíduos em tratamento. O tratamento medicamentoso da epilepsia emprega anticonvulsivantes e muitas vezes requer o uso de mais de um medicamento para tratamento, o que pode acarretar efeitos adversos a nível sistêmico e oral. Merecem atenção e cuidados odontológicos comumente o tratamento com fármacos por intermédio da administração da fenitoína, geralmente utilizada para tratamento da epilepsia, que pode trazer repercussões odontológicas e alterações periodontais, como a hiperplasia gengival. O conhecimento e a conscientização por parte dos cirurgiões dentistas acerca dos cuidados odontológicos que devem ser adotados para esses pacientes especiais portadores de epilepsia são de suma importância para realização de uma abordagem odontológica. Concluiu-se que as repercussões bucais oriundas da epilepsia devem ser identificadas e tratadas imediatamente, ao passo que o cirurgião dentista contata os pacientes enfermos, uma vez que caso contrário pode-se conviver com agravantes e piora no quadro odontológico apresentado, portanto deve-se primar por impedir a evolução desfavorável do estado de saúde bucal dos pacientes.

Epilepsy is a chronic pathology arising from an abnormal electrical brain manifestation, which causes neurological repercussions. The treatment of epilepsy employs drug administration and can also use the ketogenic diet. It is known that the use of the ketogenic diet to cope with epilepsy promotes repercussions in terms of the oral health of patients undergoing treatment. The objective of this article was to show how the use of the ketogenic diet in the therapy used to cope with epilepsy can influence the oral health of individuals undergoing treatment. Drug treatment of epilepsy uses anticonvulsants and often requires the use of more than one drug for treatment, which can lead to adverse systemic and oral effects. Treatment with drugs through the administration of phenytoin, generally used for the treatment of epilepsy, which can bring dental repercussions and periodontal changes, such as gingival hyperplasia, deserves attention and dental care. Knowledge and awareness on the part of dental surgeons about the dental care that should be adopted for these special patients with epilepsy are of paramount importance for carrying out a dental approach. It was concluded that the oral repercussions arising from epilepsy should be identified and treated immediately, while the dental surgeon contacts sick patients, since otherwise one can live with aggravating factors and worsening of the dental condition presented, therefore, one should excel in preventing the unfavorable evolution of the patients' oral health status.

Physical activity in adults with epilepsy: clinical aspects and relationship with cognition and quality of life / Atividade física em pessoas adultas com epilepsia: aspectos clínicos e as relações com a cognição e a qualidade de vida

ABSTRACT There are several factors associated with lower participation in regular physical activity (PA) in adult patients with epilepsy (PWEs). Objective: To assess the relationship between the regular practice of PA with clinical and cognitive variables and quality of life (QoL) in PWEs. Methods: Habitual Physical Activity Questionnaire (HPAQ) was related to clinical variables, scores on the Mini-Mental State Examination (MMSE), on the Brief Cognitive Battery-Edu (BCB-Edu), on the Satisfaction Scale for Physical Activity (SSPA), and on the Quality of Life in Epilepsy Inventory (QOLIE)-31 in 60 PWEs, with a significance level of p<0.05. Results: The PWEs had a mean age of 42.4±13.6 years, 50% of whom were female. Longer length of epilepsy correlated with lower PA in leisure time (Pearson correlation [r]= -0.276; p-value [p]=0.036). The occupational physical activity scores of the HPAQ correlated positively with perception (r=0.300; p=0.021), memory (r=0.381; p=0.003), semantic verbal fluency test (SVF) (r=0.427; p=0.001), and with the total score in the MMSE (r=0.327; p=0.012). The total HPAQ score correlated with the SVF (r=0.336; p=0.009) and with the MMSE (r=0.254; p=0.049). There was no correlation among the QOLIE-31, the HPAQ, and the SSPA. Conclusions: Longer duration of epilepsy was associated with the lower practice of PA. Physical activity was associated with better performance in aspects of cognition. There was no relationship between QoL and practice and satisfaction with PA, suggesting different psychosocial aspects involved.

RESUMO Existem vários fatores associados à menor participação em atividade física regular (AF) em pacientes adultos com epilepsia (PCE). Objetivo: Avaliar em PCEs a relação entre a prática regular de AF com as variáveis clínicas e cognitivas e com a qualidade de vida (QV). Métodos: Foi relacionado o Habitual Physical Activity Questionnaire (HPAQ) com as variáveis clínicas, escores no Mini-Mental State Examination (MMSE), no Brief Cognitive Battery-Edu (BCB-Edu), Satisfaction Scale for Physical Activity (SSPA) e no Quality of Life in Epilepsy Inventory (QOLIE-31) de 60 PCE, com nível de significância p<0,05. Resultados: Idade média 42,4±13,6 anos, 50% do sexo feminino. O maior tempo de epilepsia correlacionou-se com a menor prática de AF no lazer (Correlação de Person, r= -0,276; p=0,036). Escores da AF ocupacional do HPAQ correlacionaram-se positivamente com a percepção (r=0,300; p=0,021) e a memória (r=0,381; p=0,003) no teste de fluência verbal (SVF); (r=0,427; p=0,001) e com o escore total no MMSE (r=0,327; p=0,012). O escore total do HPAQ correlacionou-se com o SVF (r=0,336; p=0,009) e com o MMSE (r=0,254; p=0,049). Não houve correlação entre o QOLIE-31 com o HPAQ e a SSPA. Conclusão: A maior duração da epilepsia associou-se com a menor prática de AF. A AF associou-se com o melhor desempenho em aspectos da cognição. Não houve relação entre QV com a prática e a satisfação e a AF, sugerindo diferentes aspectos psicossociais envolvidos.

Simultaneous Estimation and Validation of Four Antiepileptic Drugs from Bulk and Formulations Using Reverse Phase HPLC

Abstract Epilepsy is a disorder of the central nervous system, in which the nerve cell activity in the brain is disturbed causing seizures. The objective was to develop an RP-HPLC method for consistent simultaneous quantitation of four antiepileptic drugs Levetiracetam (LVT), Lamotrigine (LTG), Phenobarbital (PBT) and Phenytoin (PTY). An isocratic method was developed on C18 column in JASCO HPLC using 5 mM potassium phosphate buffer (pH 6) and acetonitrile as the mobile phase at a flow rate of 1ml/min and detected at 230 nm using UV detector. The mean retention time for LVT, LTG, PBT and PTY were found as 2.55, 3.55, 4.65 and 5.99 minutes respectively. The method was validated as per ICH guidelines and was found to be acceptable. The %RSD value was <2.0 % thus stating the developed method was precise for the drugs in the given range. The accuracy values were within 85-115% of the recovery range. The specificity of the method was evaluated by an assay of marketed formulation, and it showed a percent content between 90-110% w/w for all the four drugs. The proposed analytical method was simple, accurate and robust and was precisely able to resolve the four major antiepileptic drugs. Hence, the current method can be applied successfully for routine examination of these drugs

Fármacos antiepilépticos usados en el embarazo y sus consecuencias sobre los resultados fetales: una revisión de la literatura / Antiepileptic drugs used in pregnancy and their consequences on fetal outcomes: a review of the literature

Los riesgos teratogénicos ocasionados por la exposición intrauterina a fármacos antiepilépticos (FAE) son conocidos, por lo que su prescripción se mantiene bajo estricto control. Describir los efectos adversos fetales de la exposición a FAE durante la gestación, reportados en la literatura durante el período 2016-2022. Revisión sistematizada de estudios que reportaron los efectos adversos fetales inducidos por la exposición a FAE en mujeres embarazadas en tratamiento por diagnósticos neurológicos, principalmente de epilepsia. La búsqueda se realizó en PubMed, Cochrane, Web of Science, SCOPUS, Biblioteca Virtual en Salud, Lilacs y SciELO. Se identificaron 37 artículos distribuidos en 13 países de Asia, Europa, América del Norte y Oceanía. Se observaron resultados perinatales adversos, tanto físicos como cognitivos, en la mayoría de los estudios. Los fármacos identificados como los más utilizados en los últimos años fueron valproato, topiramato, carbamazepina, lamotrigina y levetiracetam. Los FAE tienen potencial teratogénico en distintos grados de riesgo, provocando anomalías congénitas o efectos adversos en múltiples sistemas del cuerpo humano, siendo los sistemas nervioso, circulatorio y osteomuscular los más afectados.

The teratogenic risks caused by intrauterine exposure to antiepileptic drugs (AED) are known, so their prescription is kept under strict control. To describe the fetal adverse effects AED exposure during gestation, reported in the literature during the period 2016-2022. Systematized review of studies that reported fetal adverse effects induced for the exposure to AED in pregnant women in treatment for neurological diagnoses, mainly epilepsy. The search was carried out in PubMed, Cochrane, Web of Science, SCOPUS, Virtual Health Library, Lilacs and SciELO. 37 articles distributed in thirteen countries in Asia, Europe, North America and Oceania were identified. Adverse perinatal outcomes, both physical and cognitive, were observed in most studies. The most common drugs identified were valproate, topiramate, carbamazepine, lamotrigine and levetiracetam. AED have teratogenic potential in different degrees of risk, causing congenital anomalies or adverse effects in multiple systems of the human body, being the nervous, circulatory and musculoskeletal systems the most affected.

The utility of mobile telephone-recorded videos as adjuncts to the diagnosis of seizures and paroxysmal events in children with suspected epileptic seizures

Background. Epilepsy is often diagnosed through clinical description, but inter-observer interpretations can be diverse and misleading. Objective. To assess the utility of smartphone videos in the diagnosis of paediatric epilepsy.Methods. The literature was reviewed for evidence to support the use of smartphone videos, inclusive of advantages, ethical practice and potential disadvantages. An existing adult-based quality of video (QOV) scoring tool was adapted for use in children. A pilot study used convenience sampling of videos from 25 patients, which were reviewed to assess the viability of the adapted QOV tool against the subsequent diagnosis for the patients with videos. The referral mechanism of the videos was reviewed for the source and consent processes followed. Results. A total of 14 studies were identified. Methodologies varied; only three focused on videos of children, and QOV was formally scored in three. Studies found that smartphone videos of good quality assisted the differentiation of epilepsy from non-epileptic events, especially with accompanying history and with more experienced clinicians. The ethics and risks of circulation of smartphone videos were briefly considered in a minority of the reports. The pilot study found that the adapted QOV tool correlated with videos of moderate and high quality and subsequent diagnostic closure.Conclusions. Data relating to the role of smartphone video of events in children is lacking, especially from low- and middle-income settings. Guidelines for caregivers to acquire good-quality videos are not part of routine practice. The ethical implications of transfer of sensitive material have not been adequately addressed for this group. Prospective multicentre studies are needed to formally assess the viability of the adapted QOV tool for paediatric videos.

Caractéristiques de l'épilepsie chez les sujets âgés de 65 ans et plus / Characteristics of epilepsy in subjects aged 65 and over

Introduction. L'épilepsie du sujet âgé de 65 ans et plus est une pathologie plus fréquente que chez l'adulte jeune. L'objectif principal de ce travail était de faire la description clinique, étiologique et thérapeutique de l'épilepsie débutante et de l'épilepsie ancienne dans cette population. Méthodes. Il s'agissait d'une étude rétrospective et descriptive. Tout patient de 65 ans et plus, hospitalisé en neurologie ou vu en consultation d'épileptologie au CHU Pontchaillou de Rennes (France), présentant une épilepsie débutante ou une épilepsie ancienne a été inclus du 01 novembre 2018 au 30 avril 2019. Résultats. Nous avons retenu 95 patients. Quatorze patients ont été inclus pour une épilepsie débutante. Les crises focales prédominaient (50%) suivies des crises d'emblée généralisées (28,57%). L'étiologie la plus fréquente était d'origine structurelle dans 57,14% des cas avec 75 % de lésions tumorales et 25 % de lésions neuro-vasculaires. Quatre-vingt et un patients ont été retenus pour une épilepsie ancienne. Les crises focales prédominaient (41,98%) suivies des crises d'emblée généralisées (35,80%). L'étiologie la plus importante était d'origine structurelle (54,78%) avec 38,10% de lésions neuro-vasculaires suivies de lésions tumorales dans 16,68% des cas. Le lé vé tiracé tam était plus utilisé chez les patients ayant une épilepsie débutante et la lamotrigine chez les patients connus épileptiques. Conclusion. L'épilepsie chez le sujet âgé est de diagnostic diffi cile en raison d'un grand polymorphisme des crises et de l'origine souvent plurifactorielle. L'étiologie neuro-vasculaire est dominante dans cette population.

Introduction. Epilepsy in subjects aged 65 and over is a more frequent pathology than in young adults. The main objective of this work was to make the clinical, etiological, and therapeutic description of early epilepsy and old epilepsy in this population. Methods. This was a retrospective and descriptive study. Any patient aged 65 and over, hospitalized in neurology or seen in an epileptology consultation at the CHU Pontchaillou in Rennes (France), presenting with early epilepsy or old epilepsy was included from November 01, 2018, to April 30, 2019. Results. We retained 95 patients. Fourteen patients were included for early epilepsy. Focal seizures predominated (50%) followed by generalized seizures (28.57%). The most common etiology was of structural origin in 57.14% of cases with 75% tumor lesions and 25% neurovascular lesions. Eighty-one patients were selected for old epilepsy. Focal seizures predominated (41.98%) followed by generalized seizures (35.80%). The most important etiology was of structural origin (54.78%) with 38.10% of neurovascular lesions followed by tumor lesions in 16.68% of cases. Levetiracetam was used more in patients with early epilepsy and lamotrigine in patients with known epilepsy. Conclusion. Epilepsy in the elderly is difficult to diagnose due to a large polymorphism of seizures and often multifactorial origin. The neurovascular etiology is dominant in this population.

Hallazgos de autopsias en la muerte súbita en epilepsia. Revisión bibliográfica y reporte de casos / Autopsy findings in Sudden Death in Epilepsy. Bibliographic review and case repo

Introducción: La muerte súbita en epilepsia, es la complicación más temida de la epilepsia y se reconoce como una de las principales causas de muerte prematura en adultos jóvenes con epilepsia; sin embargo, aún es poco reconocida, informada y escasamente investigada por los profesionales de la salud, lo que ha condicionado al escaso progreso en su detección y prevención. Metodología: Se realizó una revisión narrativa mediante la búsqueda de artículos, en Pubmed, Google académico y Lilacs; utilizando las palabras clave en inglés y español: SUDEP, epilepsia, autopsia, autopsia molecular y sus combinaciones. Además, se analizaron cinco expedientes de la base de datos de la Dirección de Medicina Forense de Tegucigalpa, consignados como SUDEP. Resultados: De los cinco casos analizados, cuatro (80%) eran mujeres y uno hombre; cuatro (80%) no fueron presenciados y ocurrieron durante el sueño. El 80 % (4) de los casos eran menores de 40 años, los hallazgos de autopsia tanto macroscópicos, como microscópicos son similares a los reportado por otros autores. En el análisis de 28 artículos se encontró que el diagnostico de la SUDEP, aun representa un desafío. Conclusión: Pese a que hay avances significativos en la comprensión de los mecanismos y factores de riesgo que contribuyen a la SUDEP, aún es necesario realizar más investigación...(AU)

Non-Status Epilepticus female rats show seizure-like behaviors in the chronic phase of Pilocarpine experimental model / Ratas sem Status Epilepticus apresentam comportamento do tipo crise epiléptica na fase crônica do modelo experimental da Pilocarpina

Only few studies have focus on animals that received Pilocarpine (Pilo) and did not develop behavioral status epilepticus (SE) and, whether they may become epileptic in the model's chronic phase. Previews works observed mossy fiber sprouting in the hippocampus of Non-SE (NSE) rats, while others observed spontaneous and recurrent seizures (SRS) 6 - 8 months after animals received Pilo. It is known that neuronal excitability is influenced by female hormones, as well as, the occurrence of SE in castrated and non-castrated female rats. However, it is not known whether females that received Pilo and did not show SE, may have SRS. The aim of this work was to investigate whether castrated and non-castrated female rats that did not show behavioral SE after Pilo, will develop SRS in the following one-year. For that, animals received 360 mg/kg of Pilo and were video monitored for 12 months. SE females from castrated and non-castrated groups became epileptic since the first month after drug injection. Epileptic behaviors were identified watching video monitoring recordings in the fast speed. Castrated and Non castrated NSE animals showed behaviors resembling seizures described by Racine Scale stages 1 - 3. Motor alterations showed by NSE groups could be observed only when recordings were analyzed in slow speed. In addition, behavioral manifestations as, rhythmic head movements, sudden head movements, whole body movements and immobility were also observed in both, SE and NSE groups. We concluded that NSE female rats may have become epileptic. Adding to it, slow speed analysis of motor alterations was essential for the observation of NSE findings, which suggests that possibly many motor alterations have been underestimated in epilepsy experimental research.

Poucos são os estudos com foco em animais que receberam Pilocarpina (Pilo) e não desenvolveram status epilepticus (SE) comportamental e, se os mesmos se tornarão epilépticos na fase crônica do modelo. Autores observaram o brotamento das fibras musgosas no hipocampo de ratos Não-SE (NSE), enquanto outros observaram crises espontâneas e recorrentes (CER) 6 - 8 meses após receberam a droga. A excitabilidade neuronal é influenciada pelos hormônios femininos e, da mesma forma, a ocorrência de SE em ratas castradas e não-castradas. Entretanto, não é sabido se as fêmeas que não apresentam SE terão CER. O objetivo deste trabalho foi investigar se fêmeas castradas e não castradas que não tiveram SE comportamental após a injeção de Pilo desenvolverão CER dentro de um ano. Para isto, os animais receberam 360 mg/kg de Pilo e foram videomonitorados por 12 meses. As fêmeas SE castradas e não-castradas se tornaram epilépticas desde o primeiro mês pós Pilo. O comportamento epiléptico foi identificado assistindo as gravações na velocidade rápida. As fêmeas NSE castradas e não-castradas apresentaram comportamentos similares aos estágios 1 - 3 da Escala de Racine. As alterações motoras nestes grupos (NSE) foram observadas apenas quando as videomonitoração foi analisada na velocidade lenta. Além destas, manifestações comportamentais como movimentos rítmicos da cabeça, movimentos súbitos da cabeça, movimentos de todo o corpo e imobilidade também foram observadas em ambos grupos, SE e NSE. Concluímos que as fêmeas NE podem ter se tornado epilépticas. Adicionado a isto, a análise das alterações motoras na velocidade lenta foi essencial para a observação dos achados das fêmeas NSE, o que sugere que possivelmente muitas alterações motoras têm sido subestimados na pesquisa em epilepsia experimental.

OBJECTIVE@#To analyze the acupoint selection rules of acupuncture and moxibustion for post-stroke epilepsy by data mining technology.@*METHODS@#The literature regarding acupuncture and moxibustion for post-stroke epilepsy included in CNKI, VIP, Wanfang, SinoMed and PubMed databases from the establishment of the database to August 1st 2022 was retrieved. Microsoft Excel 2019 software was used to establish a database to conduct the descriptive analysis of acupoints; SPSS Modeler 18.0 Apriori algorithm was used to conduct association rule analysis; high-frequency acupoint co-occurrence network diagrams were drawn by Cytoscape3.9.0 software; SPSS Statistics 25.0 software was used to perform hierarchical cluster analysis on high-frequency acupoints and a tree diagram was drawn.@*RESULTS@#Totally 39 articles were included, and 63 prescriptions of acupuncture and moxibustion were extracted, involving 56 acupoints, with a total frequency of 516 times; the top three acupoints with the highest frequency of use were Baihui (GV 20), Fenglong (ST 40) and Neiguan (PC 6); the selected meridians were mainly the governor vessel, the hand and foot yangming meridians; the selection of acupoints were mostly in the head, neck and lower limbs; in terms of acupoint compatibility, Hegu (LI 4)-Shuigou (GV 26) and Neiguan (PC 6) had the highest confidence degree; The top 20 high-frequency acupoints could be divided into 4 effective clusters.@*CONCLUSION@#Modern acupuncture and moxibustion treatment for post-stroke epilepsy attaches great importance to the use of yang meridians and meridians with enrich qi and blood; the core prescription is Shuigou (GV 26)-Neiguan (PC 6)-Hegu (LI 4)-Baihui (GV 20). In addition, the combination of distant and near acupoints is highly valued to improve clinical efficacy.

Anticonvulsant drug regimen and cost of acute treatment for status epilepticus in a Philippine tertiary hospital: A retrospective cohort study

Background@#Status epilepticus (SE) is a neurological emergency requiring prompt evaluation and management to prevent disease refractoriness associated with significant mortality and morbidity. Thus, estimating costs attributable to the treatment of SE is important because of the severity of this disease. In the Philippines, healthcare provisions are mostly out-of-pocket expenses; hence the cost of treatment is a critical determinant for disease management. Unfortunately, the availability of data regarding the cost of illness of SE in developing countries is limited.@*Objectives@#To determine the frequently used anticonvulsant drug regimen and direct inpatient costs of acute treatment for status epilepticus within five years in a private tertiary hospital in the Philippines.@*Methods@#Records from patients diagnosed with SE who were admitted under or referred to the Adult Neurology Service in a private tertiary hospital from January 2015 to December 2019 were retrospectively evaluated. The SE type was classified as non-refractory (NRSE), refractory (RSE), and super refractory (SRSE). Demographic data, clinical features, SE type, etiology, antiepileptic drugs (AEDs) and anesthetic drugs used, total cost of AEDs and anesthetic drugs, total cost of 5-day hospitalization, and total cost of entire length of stay were recorded.@*Results@#We retrieved the records of 61 patients admitted for SE. Of these patients, 23 were classified as nonrefractory, 20 as refractory, and 18 as super refractory. Diazepam was given to all SE patients as first-line treatment. Valproic acid and levetiracetam were used as second-line treatments. The most frequently given anesthetic drug was midazolam. The mean hospitalization cost per patient was ₱52,0982.3 for SE, ₱659,638.7 for RSE, and ₱134,1451 for SRSE. The mean cost of 5-day hospitalization was ₱193,572.3 for NRSE, ₱358,808.5 for RSE, and ₱652,781 for SRSE. The mean cost of medications was ₱18,546 for NRSE, ₱30,780 for RSE, and ₱128,263 for SRSE.@*Conclusion@#The direct cost of SE varied depending on subtype and response to treatment. Costs increased with disease refractoriness. Direct inpatient treatment costs for SRSE were twice as high as that of NRSE and RSE.

Clinical features of 6 children with uridine-responsive developmental epileptic encephalopathy 50 caused by CAD gene variants / 中华儿科杂志

Objective: To analyze the clinical features of children with uridine responsive developmental epileptic encephalopathy 50 (DEE50) caused by CAD gene variants. Methods: A retrospective study was conducted on 6 patients diagnosed with uridine-responsive DEE50 caused by CAD gene variants at Beijing Children's Hospital and Peking University First Hospital from 2018 to 2022. The epileptic seizures, anemia, peripheral blood smear, cranial magnetic resonance imaging (MRI), visual evoked potential (VEP), genotype features and the therapeutic effect of uridine were descriptively analyzed. Results: A total of 6 patients, including 3 boys and 3 girls, aged 3.5(3.2,5.8) years, were enrolled in this study. All patients presented with refractory epilepsy, anemia with anisopoikilocytosis and global developmental delay with regression. The age of epilepsy onset was 8.5 (7.5, 11.0) months, and focal seizures were the most common seizure type (6 cases). Anemia ranged from mild to severe. Four patients had peripheral blood smears prior to uridine administration, showing erythrocytes of variable size and abnormal morphology, and normalized at 6 (2, 8) months after uridine supplementation. Two patients suffered from strabismus, 3 patients had VEP examinations, indicating of suspicious optic nerve involvement, and normal fundus examinations. VEP was re-examined at 1 and 3 months after uridine supplementation, suggesting significant improvement or normalization. Cranial MRI were performed at 5 patients, demonstrating cerebral and cerebellar atrophy. They had cranial MRI re-examined after uridine treatment with a duration of 1.1 (1.0, 1.8) years, indicating significant improvement in brain atrophy. All patients received uridine orally at a dose of 100 mg/(kg·d), the age at initiation of uridine treatment was 1.0 (0.8, 2.5) years, and the duration of treatment was 2.4 (2.2, 3.0) years. Immediate cession of seizures was observed within days to a week after uridine supplementation. Four patients received uridine monotherapy and were seizure free for 7 months, 2.4 years, 2.4 years and 3.0 years respectively. One patient achieved seizure free for 3.0 years after uridine supplementation and had discontinued uridine for 1.5 years. Two patients were supplemented with uridine combined with 1 to 2 anti-seizure medications and had a reduced seizure frequency of 1 to 3 times per year, and they had achieved seizure free for 8 months and 1.4 years respectively. Conclusions: The clinical manifestations of DEE50 caused by CAD gene variants present a triad of refractory epilepsy, anemia with anisopoikilocytosis, and psychomotor retardation with regression, accompanied by suspected optic nerve involvement, all of which respond to uridine treatment. Prompt diagnosis and immediate uridine supplementation could lead to significant clinical improvement.

Genetic analysis of a case of mild epilepsy due to variant of SCN9A gene / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic etiology of a patient with epilepsy and provide genetic counseling.@*METHODS@#A patient who had visited the Center for Reproductive Medicine of Shandong University on November 11, 2020 was selected as the study subject, and her clinic information was collected. Candidate variant was identified through whole exome sequencing (WES), and Sanger sequencing was used for validation. Possible transcriptional changes caused by the variant was detected by reverse transcription-PCR and Sanger sequencing.@*RESULTS@#The patient was a 35-year-old female with no fever at the onset, loss of consciousness and abnormal firing in the temporal lobe, manifesting predominantly as convulsions and fainting. WES revealed that she had harbored a heterozygous c.2841+5G>A variant of the SCN9A gene, which was verified by Sanger sequencing. cDNA sequencing confirmed that 154 bases were inserted between exons 16 and 17 of the SCN9A gene, which probably produced a truncated protein and affected the normal function of the SCN9A protein. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.2841+5G>A variant was classified as likely pathogenic (PVS1_Strong+PM2_Supporting).@*CONCLUSION@#The c.2841+5G>A variant of the SCN9A gene probably underlay the epilepsy in this patient. Above finding has enriched the variant spectrum of the SCN9A gene and provided a basis for the prenatal diagnosis and preimplantation genetic testing for this patient.

Burden of epilepsy in China and its provinces, 1990 to 2019: findings from the Global Burden of Disease Study 2019 / 中华医学杂志(英文版)

BACKGROUND@#Epilepsy accounts for a significant portion of the global disease burden. However, little is known about the disease burden of epilepsy in China and its provinces.@*METHODS@#We assessed the burden of epilepsy in China and its provinces, municipalities, and autonomous regions from 1990 to 2019. Burden was measured as incidence, prevalence, deaths, years lived with disability, years of life lost, and disability-adjusted life years (DALYs), by age, sex, year, and province. We used the Socio-Demographic Index (SDI) to determine the association between the provincial development level and age-standardized DALY rates of epilepsy from 1990 to 2019.@*RESULTS@#In 2019, epilepsy caused 1367.51 thousand (95% uncertainty interval [UI]: 979.92-1837.61 thousand) DALYs, and the age-standardized DALY rate was 99.77 (95% UI: 71.33-133.52)/100,000. The age-standardized incidence and prevalence rates for epilepsy in China were 24.65/100,000 and 219.69/100,000, increased by 45.00% (95% UI: 8.03-98.74%) and 35.72% (95% UI: 0.47-86.19%) compared with that in 1990, respectively. From 1990 to 2019, the proportion of DALY caused by epilepsy in the age group under 25 years steadily decreased. The proportion of DALYs caused by epilepsy in people aged 50 years and over increased from 9.45% and 10.22% in 1990 to 29.01% and 32.72% for male and female individuals in 2019, respectively. The highest age-standardized mortality rates were seen in Tibet (4.26 [95% UI: 1.43-5.66]/100,000), Qinghai (1.80 [95% UI: 1.15-2.36]/100,000), and Yunnan (1.30 [95% UI: 0.88-1.62]/100,000), and the lowest mortality rates were in Guangdong (0.48 [95% UI: 0.39-0.64]/100,000), Zhejiang (0.56 [95% UI: 0.44-0.70]/100,000), and Shanghai (0.57 [95% UI: 0.41-0.73]/100,000). The age-standardized DALY rates across the country and in provinces, municipalities, and autonomous regions generally decreased as their SDI increased.@*CONCLUSIONS@#The disease burden of epilepsy is still heavy in China, especially in the western provinces. The incidence and prevalence of epilepsy increased between 1990 and 2019, and the burden of epilepsy in the elderly increases gradually. This study provides evidence on epilepsy prevention and care of different regions in China.

Neuroprotective potential of cannabidiol: Molecular mechanisms and clinical implications / 中西医结合学报

Cannabidiol (CBD), a nonpsychotropic phytocannabinoid that was once largely disregarded, is currently the subject of significant medicinal study. CBD is found in Cannabis sativa, and has a myriad of neuropharmacological impacts on the central nervous system, including the capacity to reduce neuroinflammation, protein misfolding and oxidative stress. On the other hand, it is well established that CBD generates its biological effects without exerting a large amount of intrinsic activity upon cannabinoid receptors. Because of this, CBD does not produce undesirable psychotropic effects that are typical of marijuana derivatives. Nonetheless, CBD displays the exceptional potential to become a supplementary medicine in various neurological diseases. Currently, many clinical trials are being conducted to investigate this possibility. This review focuses on the therapeutic effects of CBD in managing neurological disorders like Alzheimer's disease, Parkinson's disease and epilepsy. Overall, this review aims to build a stronger understanding of CBD and provide guidance for future fundamental scientific and clinical investigations, opening a new therapeutic window for neuroprotection.
