RESUMO

BACKGROUND AND PURPOSE: The high prevalence of antiphospholipid antibodies (aPL) and antinuclear antibodies (ANA) in patients with epilepsy may be associated with either the disease itself or the antiepileptic treatment. The purpose of this prospective study was to determine the prevalence of aPL and ANA in children with idiopathic epilepsy before and during treatment with antiepileptic drugs.METHODS: aPL, including both anticardiolipin and anti-β2-glycoprotein I antibodies, and ANA statuses were determined in 40 healthy children, 30 children treated with sodium valproate (VPA) monotherapy, and 20 children treated with carbamazepine (CBZ) monotherapy before and at 6, 12, and 24 months after treatment initiation.RESULTS: Fifteen children (50%) in the VPA-treated group and 7 (35%) in the CBZ-treated group showed positivity for aPL before treatment initiation, compared with only 4 of the 40 controls. Nine children (30%) in the VPA-treated group and 4 (20%) in the CBZ-treated group showed positivity for ANA before treatment initiation, compared with only 2 of the 40 controls. The subgroup analysis found nonsignificant associations at the different time points regarding the positivity of all of the autoantibodies. Only patients treated with VPA had a significantly decreased risk of aPL positivity after 6 months of treatment.CONCLUSIONS: The increased prevalence of autoantibodies in children with idiopathic epilepsy is strongly associated with the disease itself.

RESUMO

BACKGROUND: Severe and life-threatening drug eruptions include drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). One class of medications that has been highly associated with such drug eruptions is antiepileptic drugs (AEDs). We attempt to investigate drug eruptions associated with AEDs as a class, as well as with individual AEDs, in Korea.METHODS: We used the Korea Institute of Drug Safety and Risk Management - Korea Adverse Event Reporting System (KIDS-KAERS) database, a nationwide database of adverse events reports, between January 2008 and December 2017 to investigate the reporting count of all drug eruptions and calculated the ratio of DRESS/SJS/TEN reports for each AED.RESULTS: Among a total of 2,942 reports, most were of rash/urticaria (2,702, 91.8%), followed by those of DRESS (109, 3.7%), SJS (106, 3.6%), and TEN (25, 0.85%). The common causative AEDs were lamotrigine (699, 23.8%), valproic acid (677, 23%), carbamazepine (512, 17.4%), oxcarbazepine (320, 10.9%), levetiracetam (181, 6.2%), and phenytoin (158, 5.4%). In limited to severe drug eruptions (DRESS, SJS, and TEN; total 241 reports), the causative AEDs were carbamazepine (117, 48.8%), lamotrigine (57, 23.8%), valproic acid (20, 8.3%), phenytoin (15, 6.3%), and oxcarbazepine (10, 4.2%). When comparing aromatic AED with non-aromatic AED, aromatic AEDs were more likely to be associated with severe drug eruption (aromatic AEDs: 204/1,793 versus non-aromatic AEDs: 37/1,149; OR, 3.86; 95% CI, 2.7–5.5). Death was reported in 7 cases; DRESS was the most commonly reported adverse event (n = 5), and lamotrigine was the most common causative AED (n = 5).CONCLUSION: Although most cutaneous drug eruptions in this study were rash or urticaria, approximately 8% of reports were of severe or life-threatening adverse drug reactions, such as SJS, TEN, or DRESS. When hypersensitivity skin reactions occurred, aromatic AEDs were associated with 4 fold the risk of SJS/TEN/DRESS compared with non-aromatic AEDs. Our findings further emphasize that high risk AEDs should be prescribed under careful monitoring, and early detection and prompt interventions are needed to prevent severe complications.

RESUMO

El Complejo Esclerosis Tuberosa (CET) es una enfermedad de origen genético, multisistémica de transmisión autosómica dominante, se debe a la mutación de los genes TSC1 (Tuberose Sclerosis Complex 1) y TSC2 de los cromosomas 9 y 16 respectivamente. Las manifestaciones clínicas se deben a la presencia de lesiones tumorales benignas (harmatomas) en diferentes órganos lo que genera un amplio espectro de signos y síntomas. El caso que se presenta es de una adolescente de origen aymara con epilepsia, retraso mental y lesiones dérmicas típicas. Es una enfermedad poco frecuente en nuestro medio y rara en personas de origen indígena, no encontrándose ninguna descripción en la literatura nacional. Por la multiplicidad de las manifestaciones clínicas, se hace necesario divulgar la información para que que las diferentes especialidades médicas reconozcan y diagnostiquen esta patología tempranamente para un tratamiento adecuado, oportuno y interdisciplinar.


The Tuberose Sclerosis Complex (TSC) is a genetic, multisystemic disease of autosomal dominant transmission, due to the mutation of the TSC1 and TSC2 genes of chromosomes 9 and 16 respectively. The clinical manifestations are due to the presence of benign tumor lesions (harmatomas) in different organs, which generates a wide spectrum of signs and symptoms. The case presented is that of a teenager of Aymara origin with epilepsy, mental retardation and typical skin lesions. It is a rare disease in our environment and rare in people of indigenous origin, no description found in the national literature. Due to the multiplicity of the clinical manifestations, it is necessary to disseminate the information so that the different medical specialties recognize and diagnose this pathology early for an adequate, timely and interdisciplinary treatment.

RESUMO

BACKGROUND: Autism is a challenging neurodevelopmental disorder. Previous clinical observations have suggested altered sedation requirements for children with autism. Our study aimed to test this observation experimentally in an animal model and to explore its possible mechanisms. METHODS: Eight adult pregnant female Sprague-Dawley rats were randomly divided into two groups. Four were injected with intraperitoneal sodium valproate on gestational day 12 and four were injected with normal saline. On postnatal day 28, the newborn male rats were subjected to the open-field test to confirm autistic features. Each rat was injected intraperitoneally with a single dose of propofol (50 mg/kg) or dexmedetomidine (0.2 mg/kg). The times to loss of righting reflex (LORR) and to return of righting reflex (RORR) were recorded. On the following day, all rats were re-sedated and underwent electroencephalography (EEG). Thereafter, the rats were euthanized and their hippocampal gamma-aminobutyric acid type A (GABA(A)) and glutamate N-methyl-D-aspartate (NMDA) receptor gene expressions were assessed. RESULTS: Autistic rats showed significantly longer LORR times and shorter RORR times than did the controls (median LORR times: 12.0 versus 5.0 min for dexmedetomidine and 22.0 versus 8.0 min for propofol; P < 0.05). EEG showed a low-frequency, high-amplitude wave pattern 2 min after LORR in the control rats. Autistic rats showed a high-frequency, low-amplitude awake pattern. Hippocampal GABA(A) receptor gene expression was significantly lower and NMDA gene expression was greater in autistic rats. CONCLUSIONS: This study supports the clinical observations of increased anesthetic sedative requirements in children with autism and our biochemical analyses using and glutamate receptor gene expression highlight possible underlying mechanisms.

RESUMO

Parkinson’s disease (PD) is one of the late-onset neurodegenerative movement disorder. Major pathological markers of PD include progressive loss of dopaminergic neurons, Lewy body formation, genetic mutations, and environmental factors. Epigenetic regulation of specific gene expression via impaired histone acetylation is associated with neuronal dysfunction in various neurodegenerative diseases. In this study, we hypothesized that histone deacetylase (HDAC) inhibitor, valproic acid (VPA), can improve motor function by enhancing cell survival in PD genetic model mice with LRRK2 R1441G mutation. To address this question, we administered VPA in LRRK2 R1441G transgenic mice to determine whether VPA affects 1) histone acetylation and HDAC expression, 2) dopaminergic neuron survival, 3) inflammatory responses, 4) motor or non-motor symptoms. As results, VPA administration increased histone acetylation level and the number of tyrosine hydroxylase (TH) positive neurons in substantia nigra of LRRK2 R1441G mice. VPA reduced iba-1 positive activated microglia and the mRNA levels of pro-inflammatory marker genes in LRRK2 R1441G mice. In addition, VPA induced the improvement of PD-like motor and non-motor behavior in LRRK2 R1441G mice. These data suggest that the inhibition of HDAC can be further studied as potential future therapeutics for PD.

RESUMO

The objective of this study was to compare recommendations of the Korean Medication Algorithm Project for Bipolar Disorder 2018 (KMAP-BP 2018) with other recently published guidelines for treating bipolar disorder. We reviewed a total of five recently published global treatment guidelines and compared treatment recommendation of the KMAP-BP 2018 with those of other guidelines. For initial treatment of mania, there were no significant differences across treatment guidelines. All guidelines recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or a combination of an MS with an AAP as a first-line treatment strategy for mania. However, the KMAP-BP 2018 did not prefer monotherapy with MS or AAP for psychotic mania. Quetiapine, olanzapine and aripiprazole were the first-line AAPs for nearly all phases of bipolar disorder across guidelines. Most guidelines advocated newer AAPs as first-line treatment options for all phases while lamotrigine was recommended for depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. As research evidence accumulated over time, recommendations of newer AAPs (such as asenapine, cariprazine, paliperidone, lurasidine, long-acting injectable risperidone and aripiprazole once monthly) became prominent. KMAP-BP 2018 guidelines were similar to other guidelines, reflecting current changes in prescription patterns for bipolar disorder based on accumulated research data. Strong preference for combination therapy was characteristic of KMAP-BP 2018, predominantly in the treatment of psychotic mania and severe depression. Further studies were needed to address several issues identified in our review.

RESUMO

Persistent aura without infarction is defined as an aura persisting for 1 week or more without evidence of infarction on neuroimaging. It is difficult to differentiate persistent visual aura without infarction from occipital lobe epilepsy. We report a Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy patient with prosopometamorphopsia and visual field defect improved by valproic acid. We also review ambiguity between visual aura in migraine and occipital lobe epilepsy.

RESUMO

OBJECTIVE@#To establish an improved mouse model of valproic acid (VPA)-induced autism that better mimics human autism.@*METHODS@#We established mouse models of autism in female C57 mice by intraperitoneal injection of sodium valproate either at a single dose (600 mg/kg) on day 12.5 after conception (conventional group) or in two doses of 300 mg/kg each on days 10 and 12 after conception (modified group), and the control mice were injected with saline only on day 12.5. The responses of the mice to VPA injection, the uterus, mortality rate, and abortion rate were compared among the 3 groups. The morphology and development of the offspring mice were assessed, and their behavioral ontogeny was evaluated using 3- chambered social test, social test, juvenil play test, and open field test.@*RESULTS@#The mortality and abortion rates were significantly lower in the modified model group than in the conventional group ( < 0.01). Compared with those in the control group, the offspring mice in both the conventional group and the modified group showed developmental disorders ( < 0.05). The mortality rate of the newborn mice was significantly lower in the modified group than in the conventional group with a rate of curvy tail of up to 100% ( < 0.001). The offspring mice in both the modified group and conventional group exhibited autism-like behavioral abnormalities, including social disorder and repetitive stereotyped behavior ( < 0.05).@*CONCLUSIONS@#The mouse model of autism established using the modified method better mimics human autism with reduced mortality and abortion rates of the pregnant mice and also decreased mortality rate of the newborn mice.

RESUMO

PURPOSE: Severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) to antiepileptic drug (AED), are rare, but result in significant morbidity and mortality. We investigated the major culprit drugs, clinical characteristics, and clinical course and outcomes of AED-induced SCARs using a nationwide registry in Korea. METHODS: A total of 161 patients with AED-induced SCARs from 28 referral hospitals were analyzed. The causative AEDs, clinical characteristics, organ involvements, details of treatment, and outcomes were evaluated. We compared the clinical and laboratory parameters between SJS/TEN and DRESS according to the leading causative drugs. We further determined risk factors for prolonged hospitalization in AED-induced SCARs. RESULTS: Carbamazepine and lamotrigine were the most common culprit drugs causing SCARs. Valproic acid and levetiracetam also emerged as the major causative agents. The disease duration and hospital stay in carbamazepine-induced SJS/TEN were shorter than those in other AEDs (P< 0.05, respectively). In younger patients, lamotrigine caused higher incidences of DRESS than other drugs (P= 0.045). Carbamazepine, the most common culprit drug for SCARs, was associated with a favorable outcome related with prolonged hospitalization in SJS (odds ratio, 0.12; 95% confidence interval, 0.02-0.63, P= 0.12), and thrombocytopenia was found to be a risk factor for prolonged hospitalization in DRESS. CONCLUSION: This was the first large-scale epidemiological study of AED-induced SCARs in Korea. Valproic acid and levetiracetam were the significant emerging AEDs causing SCARs in addition to the well-known offending AEDs such as carbamazepine and lamotrigine. Carbamazepine was associated with reduced hospitalization, but thrombocytopenia was a risk factor for prolonged hospitalization. Our results suggest that the clinical characteristics and clinical courses of AED-induced SCARs might vary according to the individual AEDs.

RESUMO

Antiepileptic drugs (AEDs) can induce severe cutaneous adverse reactions (SCARs) such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. We performed HLA genotyping and lymphocyte activation tests (LATs) for five AED-induced SCAR patients (three males and two females; aged 40–66 years old). Three patients were treated with carbamazepine (CBZ) for pain control, one was treated with phenytoin (PHT) for seizure prevention, and one was treated with valproic acid (VPA) for seizure prevention. One patient was diagnosed with CBZ-induced DRESS syndrome and the remaining patients were diagnosed with SJS. All patients recovered from SCARs after stopping suspicious drugs and supportive care. LATs were conducted to confirm the culprit drug responsible for inducing SCARs; and LAT results were positive for the suspected culprit drugs, in all except in one case. HLA-A,

RESUMO

BACKGROUND@#Studies on the relationship between antiepileptic drug (AED) administration and clinical outcomes in patients with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) remain scarce. Levetiracetam (LEV) is an AED that is neuroprotective in various neurologic disorders. This study aimed to determine the impact of LEV on the outcome of MELAS.@*METHODS@#A retrospective, single-center study was performed based on a large cohort of patients with MELAS with a history of seizures (n = 102). Decisions on antiepileptic therapies were made empirically. Patients were followed up for 1 to 8 years (median, 4 years) and divided into 2 groups based on whether LEV was administered (LEV or non-LEV). The modified Rankin scale (mRS) scores and mortality risks were analyzed in all patients.@*RESULTS@#LEV, carbamazepine, benzodiazepines, topiramate, oxcarbazepine, valproate, and lamotrigine were administered in 48, 37, 18, 13, 11, 9, and 9 patients, singly or in combination, respectively. The mean mRS score of the LEV group (n = 48) was lower than that of the non-LEV group (n = 54; mean ± standard deviation, 2.79 ± 1.47 vs. 3.83 ± 1.93, P = 0.006) up to the end of the study. Nevertheless, there was no difference in the proportion of subjects without disability (mRS ranging 0-1) between the groups (P = 0.37). The multivariate regressions revealed that LEV treatment was associated with lower mRS scores (odds ratio 0.32, 95% confidence interval [CI] 0.15-0.68, P = 0.003) and mortality rates (hazard ratio 0.24, 95% CI 0.08-0.74, P = 0.013). There was a significant difference in the Kaplan-Meier survival curves between the groups (χ = 4.29, P = 0.04).@*CONCLUSIONS@#The LEV administration is associated with lower mortality in patients with MELAS in this retrospective study. Further laboratory research and prospective cohort studies are needed to confirm whether LEV has neuroprotective effects on patients with mitochondrial diseases.

RESUMO

Tyrosine phosphorylated proteins have been localized and identified in male reproductive tissues such as testis and capacitated/ acrosome reacted sperm except epididymis. The changes of such proteins are associated with decreased sperm quality of valproic acid treatment. This study aimed to investigate the presence and alterations of protein phosphorylation in epididymal epithelium and fluid of rats treated VPA. Sixteen adult male rats were divided into control and VPA-treated groups (n=8/ each). Treated rats were injected with VPA (500 mg/ kgBW, intraperitoneally) for 10 consecutive days. At the end of experiment, the monoclonal antiphosphotyrosine (clone 4G10) was used for immunohistochemistry to probe tyrosine phosphorylated proteins and also to examine the expression of such proteins using immuno-Western blotting in epididymal tissue and fluid. The result showed that positive reactivity of phosphorylated proteins was clearly observed in cytoplasmic principle cells, nuclei of apical & basal cells and sperm mass surrounded with epididymal fluids. The profiles of phosphorylated proteins in epididymal fluid were 182, 127, 80, 70, 57, 45, 34, and 31 kDas, respectively. Interestingly, VPA affected the changes of phosphorylated proteins and β actin in head, body, and tail epididymal fluids. We conclude that tyrosine phosphorylated proteins were detected in epididymal epithelium and fluid. The expressions of those proteins and actin were altered under VPA treating.


Las proteínas tirosina fosforiladas han sido localizadas e identificadas en tejidos reproductores masculinos tales como testículos y espermatozoides, capacitados a nivel acrosómico, excepto en el epidídimo. Los cambios de estas proteínas están asociadas con una disminución de la calidad del esperma en el tratamiento con ácido valproico (AVP). Este estudio tuvo como objetivo investigar la presencia y las alteraciones de la fosforilación de proteínas en el epitelio epididimal y en el fluido espermático de ratas tratadas con AVP. Dieciséis ratas macho adultas se dividieron en dos grupos: control y tratadas con AVP (n = 8 / cada uno). A las ratas tratadas se les inyectó AVP por vía intraperitoneal (500 mg / kg de peso corporal) durante 10 días consecutivos. Al final del experimento, se realizó inmunohistoquímica con la anti-fosfotirosina monoclonal (clon 4G10) para sondear las proteínas tirosina fosforiladas y también para examinar la expresión de tales proteínas usando inmunotransferencia Western, en tejido y fluido epididimarios. El resultado mostró reactividad positiva de proteínas fosforiladas en células citoplásmicas principales, en los núcleos de las células apicales y basales y en la masa de esperma rodeada por fluidos epididimarios. Los perfiles de proteínas fosforiladas en el fluido epididimal fueron 182, 127, 80, 70, 57, 45, 34 y 31 kDas, respectivamente. El AVP provocó cambios en las proteínas fosforiladas y en la β actina de los fluidos epididimarios de cabeza, cuerpo y cola del epidídimo. Concluimos que las proteínas tirosina fosforiladas se detectaron en el epitelio y el fluido epididimarios. Las expresiones de esas proteínas y de la β actina se alteraron bajo tratamiento con AVP.

RESUMO

El ácido valproico es una droga ampliamente usada desde su autorización por la FDA y a la fecha es usada en esquemas de monoterapia o combinada con otros anticonvulsivantes para diferentes tipos de crisis. El ácido valproico muestra ventajas sobre otros anticonvulsivantes por mostrar menores efectos adversos, así como una menor frecuencia de disfunción cognitiva y efectos del sistema nervioso central, lo que permite estar más alerta; dentro de sus efectos adversos están las náuseas, vómitos y temblores. Los efectos tóxicos pueden ser dependientes de dosis o idiosincrásicos. De las idiosincrasias se describe la alopecia, aplasia medular, hepatotoxicidad inmunomediada y pancreatitis. Los casos reportados de pancreatitis asociados a ácido valproico son pocos y en general la mayoría son leves y autolimitados. Reportamos un caso de pancreatitis con efusión pleural izquierda, trombosis venosa portal y esplénica con subsecuente pseudoquiste pancreático


Valproic acid is a widely used drug since its authorization by the FDA and to date it is used in monotherapy schemes or combined with other anticonvulsants for different types of seizures. Valproic acid shows advantages over other anticonvulsants because it shows less adverse effects, as well as a lower frequency of cognitive dysfunction and central nervous system effects, which allows to be more alert; Nausea, vomiting and tremors are among its adverse effects. The toxic effects can be dose dependent or idiosyncratic. Alopecia, medullar aplasia, immune-mediated hepatotoxicity and pancreatitis are described in the idiosyncrasies. The reported cases of pancreatitis associated with valproic acid are few and in general most are mild and self-limiting. We report a case of pancreatitis with left pleural effusion, portal vein thrombosis and splenic with subsequent pancreatic pseudocyst.

RESUMO

Although Momordica charantia (MC) has preventive effects on tissue injuries, antioxidant capacity and protective effect of MC pulp and peel (MCP) on valproic acid (VPA)-testicular damage have never been reported. Fresh MCPs were aqueous extracted and determined for antioxidant capacity and momordicine I level by HPLC. Male rats were divided into 5 groups (control, VPA (500 mg/kgBW), MCP20/40/ or 80 mg/kgBW+VPA). In 30 experimental days, animals were pretreated with different doses of MCPs for 20 days before VPA injection for 10 consecutive days. Sperm concentration, testosterone hormone, and testicular histology of all groups were investigated. Expressions of testicular tyrosine phosphorylated and steroidogenic acute regulatory (StAR) proteins were examined by Western blot. Results showed that MCP contains TPC (39.24±0.65 ug/mg garlic acid), antioxidant capacities (FRAP=33.08±0.21 ug/ mg ascorbic acid equivalent, IC50 of DPPH=389.8±3.20 ug/ml), and momordicine I (404.9 mg/g MCP). Sperm concentration in MCP80+VPA group was increased as compared to VPA group. Testosterone level in MCP treated groups was significantly increased. MCP protected testicular damage and could prevent the decrease of StAR and a 50-kDa phosphorylated protein expression in VPAtreated testis. In conclusion, MCP has antioxidant activities and can prevent male reproductive toxicity in VPA-induced rats.


A pesar que la Momordica charantia (MC) tiene efectos preventivos sobre las lesiones en los tejidos, capacidad antioxidante y un efecto protector de la pulpa y la cáscara de MC (CMC) sobre el ácido valproico (AVP), aún no se ha informado efectos sobre el daño testicular. Las CMC frescas fueron extraídas de forma acuosa y se determinó la capacidad antioxidante y el nivel de Momordicina I por HPLC. Las ratas machos se dividieron en 5 grupos: control, AVP (500 mg/kg de peso corporal), CMC20 / 40 / u 80 mg/kg de peso corporal + AVP . En 30 días experimentales, los animales fueron pretratados con diferentes dosis de CMC durante 20 días antes de la inyección de AVP durante 10 días consecutivos. Se investigó la concentración de espermatozoides, la hormona testosterona y la histología testicular de todos los grupos. Las expresiones de proteínas reguladoras agudas (StAR) fosforiladas con tirosina y esteroidogénicas testiculares se examinaron mediante inmunotransferencia de tipo Western. Los resultados mostraron que CMC contiene TPC (39.24 ± 0.65 ug / mg de ácido de ajo), capacidades antioxidantes (FRAP = 33.08 ± 0.21 ug / mg de ácido ascórbico equivalente, IC50 de DPPH = 389.8 ± 3.20 ug / ml) y momordicina I (404.9 mg) / g CMC). La concentración de esperma en el grupo MCP80 + AVP aumentó en comparación con el grupo AVP. El nivel de testosterona en los grupos tratados con CMC aumentó significativamente. La CMC protegió el daño testicular y pudo prevenir la disminución de StAR y una expresión de proteína fosforilada de 50 kDa en los testículos tratados con AVP. En conclusión, la CMC tiene efectos antioxidantes y puede prevenir la toxicidad reproductiva en ratas machos inducidas por VPA.

RESUMO

Introducción. Las crisis convulsivas son la urgencia neurológica más frecuente en pediatría, llegando a ser una urgencia vital, sobre todo cuando se presentan status convulsivos que ameritan vigilancia en unidad de cuidados intensivos pediátricos (UCIP). Materiales y métodos. La población de estudio fue un total de 60 pacientes menores de 18 años hospitalizados en UCIP en un hospital ubicado en Cartagena-Colombia. La data resultante se le calculó estadísticos univariados de tendencia central y proporciones, como tablas de frecuencia univariada y bivariadas. Resultados. Se obtuvo una población de 60 pacientes en edad pediátrica, con edad promedio de 3.85 años, teniendo antecedente de epilepsia el 64.81% y el 23,33% parálisis cerebral, la comorbilidad con mayor frecuencia fue la infección meníngea con un 25.71%. Los pacientes con antecedentes de epilepsia el medicamento más utilizado ambulatoriamente fue el ácido valproico con 48.33%, seguidamente de levetiracetam 26.67% y carbamazepina 13.33%. Dentro de la población estudiada el 83.33% presento status convulsivos, siendo la crisis tónico clónica generalizada el tipo de crisis más frecuentemente descrita con un porcentaje del 88%, los medicamentos anticonvulsivantes más utilizados para yugular crisis, se encontró el midazolam con un 98.33%. El 95% salió vivo de la institución y un 5% falleció. Conclusiones. Las principales causas de status epiléptico se encuentran la lesión cerebral aguda, convulsiones febriles atípicas, epilepsia y enfermedades degenerativas, lo que concuerda con lo descrito en la literatura, los medicamentos anticonvulsivantes más utilizados en UCIP son el midazolam en primera estancia y el ácido valproico en segunda estancia.


Introduction. Seizures are the most frequent neurological urgency in pediatrics, becoming a vital urgency, especially when there are convulsive states that merit surveillance in a pediatric intensive care unit (PICU). Materials and methods. The study population was a total of 60 patients under the age of 18 hospitalized in PICU in a hospital located in Cartagena-Colombia. The resulting data were calculated univariate statistics of central tendency and proportions, such as univariate and bivariate frequency tables. Results. A population of 60 pediatric patients with a mean age of 3.85 years was obtained, having a history of epilepsy in 64.81% and 23.33% in cerebral palsy. The most common comorbidity was meningeal infection with 25.71%. Patients with a history of epilepsy, the most widely used outpatient medication was valproic acid with 48.33%, followed by levetiracetam 26.67% and carbamazepine 13.33%. Within the study population, 83.33% presented convulsive status, with the generalized clonic tonic crisis being the most frequently described type of crisis with a percentage of 88%, the most used anticonvulsant drugs for jugular crisis, midazolam was found with 98.33%. 95% left the institution alive and 5% died. Conclusions. The main causes of epileptic status are acute brain injury, atypical febrile seizures, epilepsy and degenerative diseases, which is consistent with what has been described in the literature, the most used anticonvulsant medications in PICU are midazolam in the first stay and valproic acid In second stay.

RESUMO

Palatal myoclonus (PM) is a rare disease that may induce dysphagia. Since dysphagia related to PM is unique and is characterized by myoclonic movements of the involved muscles, specific treatments are needed for rehabilitation. However, no study has investigated the treatment effectiveness for this condition. Therefore, the aim of this case report was to describe the benefit of combining behavioral treatment with valproic acid administration in patients with dysphagia triggered by PM. The two cases were treated with combined treatment. The outcomes evaluated by videofluoroscopic swallowing studies before and after the treatment showed significant decreases in myoclonic movements and improved swallowing function. We conclude that the combined treatment was effective against dysphagia related to PM.

RESUMO

BACKGROUND: Chronic inflammation can lower the seizure threshold and have influence on epileptogenesis. The components of red ginseng (RG) have anti-inflammatory effects. The abundance of peripherally derived immune cells in resected epileptic tissue suggests that the immune system is a potential target for anti-epileptogenic therapies. The present study used continuous electroencephalography (EEG) to evaluate the therapeutic efficacy of RG in intrahippocampal kainic acid (IHKA) animal model of temporal lobe epilepsy.METHODS: Prolonged status epilepticus (SE) was induced in 7-week-old C57BL/6J mice via stereotaxic injection of kainic acid (KA, 150 nL; 1 mg/mL) into the right CA3/dorsal hippocampus. The animals were implanted electrodes and monitored for spontaneous seizures. Following the IHKA injections, one group received treatments of RG (250 mg/kg/day) for 4 weeks (RG group, n=7) while another group received valproic acid (VPA, 30 mg/kg/day) (VPA group, n=7). Laboratory findings and pathological results were assessed at D29 and continuous (24 h/week) EEG monitoring was used to evaluate high-voltage sharp waves on D7, D14, D21, and D28.RESULTS: At D29, there were no differences between the groups in liver function test but RG group had higher blood urea nitrogen levels. Immunohistochemistry analyses revealed that RG reduced the infiltration of immune cells into the brain and EEG analyses showed that it had anticonvulsant effects.CONCLUSION: Repeated treatments with RG after IHKA-induced SE decreased immune cell infiltration into the brain and resulted in a marked decrease in electrographic seizures. RG had anticonvulsant effects that were similar to those of VPA without serious side effects.
