Encefalitis de Hashimoto. Presentación de un caso / Hashimoto Encephalitis. Case Report

INTRODUCCIÓN La Encefalitis de Hashimoto (EH) es una encefalopatía de naturaleza autoinmune, con buena respuesta al tratamiento con corticoides, títulos séricos elevados de anticuerpos antitiroideos y de curso subagudo con recaídas-remisiones. Es una enfermedad poco frecuente, con una presentación clínica variable y fisiopatología aún desconocida. PRESENTACIÓN DEL CASO: Paciente femenina de 76 años con antecedentes de hipotiroidismo primario. Ingresó con un síndrome confusional agudo. Al examen físico vigil, Glasgow 13/15, subfebril (37.8°C) desorientada temporoespacialmente, ecolalia, pupilas isocóricas y reactivas, sin focalidad neurológica. Signos meníngeos negativos. Laboratorio: Hipocalcemia leve (7.8mg/dl), hipopotasemia (K 3,2 mmol/l), PCR 221.9 mg/L. Test rápido para VIH negativo. TC de encéfalo sin alteraciones. Punción lumbar líquido cristal de roca, proteínas 1 g/l, glucosa 0.67 g/l, láctico 1.3, leucocitos 77 células/microL (100% mononucleares). Se interpretó inicialmente como Encefalitis de etiología viral y se le indicó aciclovir. Presentó sensorio alternante, excitación psicomotriz y convulsión tónica clónica generalizada. Debido a deterioro súbito del sensorio, se realizó intubación orotraqueal y se trasladó a Unidad de Terapia Intensiva (UTI). Permaneció bajo asistencia mecánica ventilatoria y con vasopresores. Laboratorio: VDRL, p24 y anticuerpos HIV negativos, TSH 27,82, T4 0,41. PCR de LCR: Virus herpes simple 1 y 2, citomegalovirus y JC negativos. Hemocultivos negativos. Ante sospecha clínica de Encefalitis de Hashimoto, se solicitaron anticuerpos antitiroideo peroxidasa (aTPO), antitiroglobulina (aTG) y Anticuerpos Anti-Receptor de TSH (TRABS), que resultaron positivos. Recibió tratamiento con levotiroxina endovenosa e hidrocortisona. Normaliza valores. Por fallo en el weaning, se realizó traqueostomía. Luego de 21 días de internación en Terapia Intensiva pasó a clínica con posterior alta hospitalaria. Discusión: La EH se puede considerar como diagnóstico, solo después de descartar otras causas. En el caso expuesto se llegó al diagnóstico luego de descartar otras causas posibles, con anticuerpos antitiroideos positivos en altas concentraciones y respuesta al tratamiento con corticoides. Conclusión: Se destaca la necesidad de ampliar el conocimiento de esta patología con el fin de disminuir el subdiagnóstico y promover un inicio precoz del tratamiento, mejorando así su progresión y calidad de vida de los pacientes.

INTRODUCTION: Hashimoto's Encephalitis (HE) is an autoimmune encephalopathy, with a good response to treatment with corticosteroids, high serum titers of antithyroid antibodies and a subacute course with relapses-remissions. It is a rare disease, with a variable clinical presentation and still unknown pathophysiology. CASE REPORT: A 76-year-old female patient with a history of primary hypothyroidism. She was admitted with acute confusional syndrome. On physical examination, she was awake, she was Glasgow 13/15, she was subfebrile (37.8°C), disoriented temporally, echolalia, isochoric and reactive pupils, without neurological focality. Negative meningeal signs. Laboratory: Mild hypocalcemia (7.8 mg/dl), hypokalemia (K 3.2 mmol/l), CRP 221.9 mg/L. Rapid test for HIV negative. Brain CT without alterations. Lumbar puncture rock crystal liquid, proteins 1 g/l, glucose 0.67 g/l, lactic acid 1.3, leukocytes 77 cells/microL (100% mononuclear). It was initially interpreted as Encephalitis of viral etiology and acyclovir was prescribed. He presented alternating sensory, psychomotor excitement, and generalized tonic-clonic seizure. Due to sudden deterioration of the sensorium, orotracheal intubation was performed and he was transferred to the Intensive Care Unit. He remained under mechanical ventilatory assistance and with vasopressors. Laboratory: VDRL, p24 and HIV antibodies negative, TSH 27.82, T4 0.41. CSF PCR: Herpes simplex virus 1 and 2, cytomegalovirus and JC negative. Negative blood cultures. Due to clinical suspicion of Hashimoto's Encephalitis, anti-thyroid peroxidase (aTPO), anti-thyroglobulin (aTG) antibodies and Anti-TSH Receptor Antibodies (TRABS) were requested, which were positive. She was treated with intravenous levothyroxine and hydrocortisone. Normalized values. Due to weaning failure, a tracheostomy was performed. After 21 days of hospitalization in the Intensive Care Unit, she was admitted to the clinic and subsequently discharged from the hospital. Discussion: HD can be considered as a diagnosis, only after ruling out other causes. In the case presented, the diagnosis was made after ruling out other possible causes, with positive antithyroid antibodies in high concentrations and response to treatment with corticosteroids. Conclusion: The need to expand knowledge of this pathology is highlighted in order to reduce underdiagnosis and promote early initiation of treatment, thus improving its progression and quality of life of patients.

Manifestaciones neurológicas en pacientes pediátricos con síndrome urémico hemolítico / Neurological manifestations in pediatric patients with hemolytic uremic syndrome

[RESUMEN]. El síndrome urémico hemolítico (SUH) es una entidad endémica en nuestro país y constituye la primera causa de insuficiencia renal aguda en la edad pediátrica y la segunda de insuficiencia renal crónica. Se define por la aparición simultánea de anemia hemolítica microangiopática, trombocitopenia y daño parenquimatoso renal. Las manifestaciones iniciales incluyen insuficiencia renal aguda, hipertensión arterial y sintomatología neurológica hasta en un 30% de los casos aproximadamente. Dentro de las manifestaciones del sistema nervioso central se encuentran las convulsiones, irritabilidad, letargo, encefalopatía y coma. (1,2) Realizamos un estudio descriptivo, retrospectivo a partir de la revisión de historias clínicas de 53 pacientes menores de 16 años de edad, con diagnóstico de SUH derivados al servicio de pediatría, tanto cuidados intermedios como UTIP del Hospital El Cruce en el periodo de tiempo de enero del 2010 hasta septiembre del 2023 con el objetivo de describir la tasa de afectación neurológica y evaluar secuelas a largo plazo. Conclusiones: De los 53 niños con diagnóstico de SUH, 14 presentaron manifestaciones a nivel del SNC, es decir un 26% del total. Las manifestaciones que prevalecieron fueron las convulsiones y el estatus convulsivo. 3 de 14 pacientes permanecieron con secuelas neurológicas, los 11 restantes presentaron recuperación completa (89%). Si bien la afectación neurológica es menos común que la afectación renal, sigue siendo una causa de mortalidad aguda y discapacidad a largo plazo entre los pacientes con SUH.

[ABSTRACT]. Hemolytic uremic syndrome is an endemic entity in our country which establishes the main cause of acute kidney failure in children. It also represents the second cause of chronic kidney failure. Its main clinical manifestations are microangiopathic hemolytic anemia, thrombocytopenia and kidney injury. Early clinical manifestations are characterized by hypertension, acute kidney failure and neurological involvement in up to 30% of children with HUS. Seizures, irritability, lethargy, encephalopathy, and coma are the most common central nervous system manifestations. (1,2) We identified 53 children under the age of 16, between January 2010 and September 2023 with a confirmed diagnosis of SUH at El Cruce hospital . Patients came from intermediate care or had PICU admission. Our objective was to describe the neurological involvement rate in HUS and long term sequels. Of the 53 patients with HUS, 14 had central nervous system manifestations, which represents 26% of children with the diagnosis. Most frequent manifestations included seizures and convulsive status. 3 of 14 patients remained with neurological sequels, the last 11 showed total recovery. Even though Neurological involvement is less common than renal injury, it still represents one of the causes of acute mortality and long term disability in patients with HUS.

INTRODUCTION: Cerebral small vessel disease is a leading cause of functional loss, disability, and cognitive impairment. OBJECTIVE: To determine the prevalence of small vessel disease and clinical characteristics associated with greater functional, cognitive and affective impairment in older adults with cerebrovascular disease attended at the Neurology Service of the Carlos Andrade Marín Hospital in the period 2020 - 2021. METHODOLOGY: Observational, analytical cross-sectional study with 80 patients over 65 years of age with previously diagnosed cerebrovascular disease. It was determined which patients had cerebral small vessel disease. The two groups of ischemic cerebrovascular disease with and without cerebral small vessel disease were compared. The degree of functional impairment was measured with the Barthel, Lawton and Brody scales. Cognitive impairment was measured with the Montreal Cognitive Assessment-Basic test, and affective state with the Yesavage scale. Odds ratio was used and a p value <0,05 was considered significant. Statistical Package for Social Sciences version 25 was used. RESULTS: Males represented 51,2%. Mean age was 76,2 years. Prevalence of cerebral small vessel disease (87,5%). Fazekas scale grade 1 (46,3%), Factors associated with cerebral small vessel disease: smoking [RR: 7,27; 95% CI: 1,69-31,3); chronic kidney disease [RR: 4,0; 95% CI: 1,01-15,7]. Moderate dependence [RR: 6,42; 95% CI: 1,02-40,3]. Factors associated with loss of function: severity of stroke. Factors associated with cognitive impairment: infarction with double territory. Factors associated with affective impairment: dual territory infarction and metabolic syndrome (p<0.05). CONCLUSION: Cerebral small vessel disease has a high prevalence among older adults with cerebrovascular disease and represented a considerable cognitive, functional and affective deterioration, in relation to patients without this disease.

Encefalopatía de Hashimoto. Un diagnóstico por exclusión y revisión de la literatura a partir de un reporte de caso / Hashimoto Encephalopathy as Diagnosis by Exclusion Review of the Literature from a Case Report

La encefalopatía de Hashimoto es una entidad poco frecuente, con una amplia gama de manifestaciones neurológicas que incluyen déficits focales, alteraciones cognitivas, crisis convulsivas, trastorno del movimiento e incluso el coma. Con un curso de la enfermedad de subagudo a fluctuante. Afecta más a mujeres que a hombres, con edad de presentación alrededor de los 44 años, aunque se han reportado casos en la edad pediátrica. De etiología poco clara, se desarrolla en el contexto de la presencia de anticuerpos antitiroideos, independientemente de la función tiroidea. La presencia de estos anticuerpos, sumado a la exclusión de otras etiologías y la respuesta al manejo esteroide son claves para su diagnóstico. Presentamos un caso clínico de una mujer de 57 años de edad que evoluciona con psicosis, alteración del lenguaje, deterioro cognitivo, mioclonías y crisis convulsivas de 5 meses de evolución, quien se excluyó otras causas de demencia rápidamente progresiva con presencia de anticuerpos anti tiroglobulina de 83,6 UI/mL (V.R. < 100 UI/mL) normal y anti tiroperoxidasa en 217 UI/mL (V.R. < 100 UI/mL) elevado. Recibió valoración por el Servicio de Endocrinología, donde se detectó hipotiroidismo y se indicó manejo con levotiroxina sin mejoría del cuadro neurológico. Se indicó manejo esteroide con pulsos de metilprednisona a 500 mg/día por 5 días, con mejoría clínica y se concluyó por criterios de exclusión como una encefalopatía de Hashimoto(AU)

Hashimoto encephalopathy is a rare entity, with wide range of neurological manifestations including focal deficits, cognitive alterations, seizures, movement disorders, and even coma, with a subacute to fluctuating disease course. It affects more women than men, it has age of presentation around 44 years, although cases have been reported in the pediatric age. Its etiology is unclear, it develops in the presence of antithyroid antibodies, regardless of thyroid function. The presence of these antibodies, added to the exclusion of other etiologies and the response to steroid management are key to the diagnosis. We report a clinical case of a 57-year-old woman who evolved with psychosis, language impairment, cognitive impairment, myoclonus, and seizures of 5 month-duration. Other causes of rapidly progressive dementia with the presence of normal antithyroglobulin antibodies of 83.6 IU/mL (RV < 100 IU/mL) and elevated antithyroperoxidase 217 IU/mL (RV < 100 IU/mL) were excluded. She was evaluated in the Endocrinology Department that detected hypothyroidism and indicated management with levothyroxine with no improvement in the neurological condition. Steroid management with methylprednisone pulses at 500 mg/day for 5 days was indicated. Clinical improvement was observed and was concluded to be a Hashimoto encephalopathy by exclusion criteria(AU)

Hypophysitis an uncommon manifestation of IgG4-related disease: Case report

IgG4-related disease is a recently described disease that can involve various organs and systems. Single organ involvement is the exception to the rule, it is generally a multi-system entity. We present a 36-year-old woman, with no previous pathological history or autoimmune disease, with headache caused by cystic macroadenoma. A transsphenoidal resection was performed and pathology documented areas of fibrosis with a predominantly plasmolymphocytic infíltrate and positive IgG4 staining in more than 20 cells per high-power field, meeting diagnostic criteria for IgG4-related sclerosing disease. Involvement of other organs was ruled out, and the patient improved clinically after management.

La enfermedad relacionada con IgG4 es una entidad recientemente descrita, capaz de involucrar diversos órganos y sistemas. El compromiso de órganos aislados es la excepción a la regla, dado que generalmente se trata de una entidad multisistémica. Se presenta el caso de una mujer de 36 años, sin antecedentes patológicos previos, en quien como causa de cefalea se documenta un macroadenoma quístico llevado a resección transesfenoidal, cuyo resultado de patología documenta zonas de fibrosis con infiltrado de predominio plasmo-linfocitario y la tinción para IgG4 positiva en más de 20 células por campo de alto poder, lo que configura criterios diagnósticos para enfermedad esclerosante relacionada con IgG4; se descartó compromiso de otros órganos y hubo mejoría clínica posterior al manejo.

Permitted daily exposure from preclinical studies of Ginkgo biloba L. dry extract

Abstract Resolution 658/2022 of the Brazilian Regulatory Agency requires the determination of the permitted daily exposure (PDE) of pharmaceutical agents. Ginkgo biloba L. is used therapeutically to treat memory deficits and other brain diseases. However, published results indicate that more studies are needed to confirm the safety of Ginkgo biloba. This study aimed to evaluate the dry extract of Ginkgo biloba L. leaves PDE as an ingredient in an oral pharmaceutical product in preclinical studies using mice. Acute oral toxicity and repeated dose experiments were performed based on OECD guidelines, as well as genotoxicity tests. The results indicate that Ginkgo biloba L. has low acute toxicity, no liver toxicity, and does not alter blood glucose levels. No changes in weight gain were observed, but food intake decreased in males during the first week of treatment at the highest dose. Hematological parameters were not altered in males, whereas females presented lower leukocyte and lymphocyte counts and higher neutrophil counts at the highest dose. The lipid profile was not altered in males, whereas total cholesterol was increased in females. The estimated PDE was 0.1 mg/day and, when related to the maximum residual concentration, indicates that the cleaning process used is safe and does not require reassessment.

La encefalopatía de Hashimoto es una enfermedad rara reportada por primera vez en 1966 con una prevalencia de 2,1/1000 habitantes. Se presenta el caso de una mujer de 42 años, sin antecedentes médicos de importancia, quien inició un cuadro de manera súbita con alteración de conciencia, alucinaciones visuales y delusiones. En los exámenes de laboratorio se tuvo anticuerpos antiperoxidasa tiroidea mayor a 600 U/ml, tiroxina 0,93, hormona estimulante de la tiroides 1,60 U/ml, resonancia magnética con lesiones focales subcorticales bilaterales de aspecto desmielinizante inespecífico, electroencefalograma sin particularidades. Se realizó el diagnóstico de encefalopatía de Hashimoto y el cuadro remitió luego del tratamiento con corticoides. El artículo resalta la importancia de realizar una evaluación integral de los pacientes con sintomatología psiquiátrica atípica y ahondar en el diagnóstico de exclusión.

Hashimoto's encephalopathy is a rare disease, first reported in 1966, with a prevalence of 2.1 in 1000 inhabitants. We present the case of a 42- year- old woman, with no relevant medical history, who suddenly started having symptoms of altered consciousness, visual hallucinations and de-lusions. Laboratory tests showed anti- thyroperoxidase antibodies greater than 600 U/ml, thy-roxin 0.93 U/ml, and thyroid stimulating hormone 1.60 U/ml. Magnetic resonance imaging showed bilateral subcortical focal lesions with a nonspecific demyelinating appearance. The electroencephalogram was nonspecific. The diagnosis of Hashimoto encephalopathy was made, and symptoms remitted after treatment with steroids. This article highlights the importance of conducting a comprehensive evaluation of patients with atypical psychiatric symptoms and a thorough differential diagnosis.

Riesgos modificables relacionados a la hipertensión arterial / Modifiable risks related to hypertension arterial

La hipertensión arterial (HTA) es una de las causas de muertes a nivel mundial, esta enfermedad incrementa significativamente los riesgos de sufrir cardiopatías, encefalopatías, nefropatías y otras enfermedades. Su prevalencia está asociada a países de bajos y medianos ingresos, y se consideran factores de riesgos al estrés, alcoholismo, obesidad, tabaquismo, drogas, alimentación, genética, raza, y ciertas patologías como diabetes mellitus, algunas de ellas consideradas como factores de riesgo modificables y que pueden ser medidas de prevención y control en su tratamiento. Objetivo: Recopilar información sobre los transcriptores riesgos modificables relacionados a la hipertensión arterial. Materiales y Métodos: El estudio es del tipo descriptivo, La metodología es una revisión narrativa, con recopilación de literatura referente al tema y disponible en la web, se emplearon los descriptores: hipertensión, factores de riesgo. Resultados: Aporte de información relevante sobre los factores de riesgos modificables entre ellos el consumo de tabaco y alcohol, reducción de peso, alimentación, actividades físicas, reducción del consumo de sal, aumento del consumo de hortalizas y frutas, además de la disminución en el consumo de alimentos grasos, sales, y un control periódico de la tensión arterial, bajo la supervisión médica que son considerados para la prevención y control de la HTA, como métodos alternativos para control y prevención de esta enfermedad. Conclusiones: Los factores de riesgo modificables que predominan son el consumo de grasas, ausencia del control del índice de masa corporal y de la presión arterial, así como el consumo excesivo de sal y presencia de estrés. Los factores de riesgo no modificables que predisponen a hipertensión arterial prevalentemente son los antecedentes familiares de HTA y de obesidad. Se ha determinado que los cambios en el estilo de vida, así como una conducta sana para la prevención y control de riesgos que son modificables atenúan la prevalencia de la misma(AU)

Arterial hypertension (AHT) is one of the causes of death at the Worldwide, this disease significantly increases the risk of heart disease, encephalopathies, nephropathies and other diseases. Its prevalence is associated with countries of low and medium income, and are considered risk factors for stress, alcoholism, obesity, smoking, drugs, food, genetics, race, and certain pathologies such as diabetes mellitus, some of them considered as modifiable risk factors and that can be prevention and control measures in their treatment. Objective: Collect information on transcriptionists modifiable risks related to hypertension arterial. Materials and methods: The study is of the descriptive type, the methodology is a narrative review, with a compilation of literature on the subject and available on the web, used the descriptors: hypertension, risk factors. Results: Contribution of relevant information on modifiable risk factors, including the consumption of tobacco and alcohol, weight reduction, nutrition, physical activities, reduction of salt intake, increased consumption of vegetables and fruits, in addition to the decrease in the consumption of fatty foods, salts, and periodic control of blood pressure, under the medical supervision that are considered for the prevention and control of hypertension, such as alternative methods for control and prevention of this disease. Conclusions: The modifiable risk factors that predominate are the consumption of fats, absence of control of body mass index and blood pressure, as well as excessive consumption of salt and presence of stress. Non-modifiable risk factors that predispose to high blood pressure are predominantly a family history of hypertension and obesity. It has been determined that changes in lifestyle, as well as behavior healthy for the prevention and control of risks that are modifiable attenuate the prevalence ofthe same(AU)

Vitamin D3 mediates spatial memory improvement through nitric oxide mechanism in demyelinated hippocampus of rat

Abstract Studies have revealed beneficial role of vitamin D3 in neuro-cognitive function. There is also supporting evidence on the involvement of nitric oxide (NO) in the neuro-protective action. However, its over production could contribute to brain disorders. In this study, demyelination was induced by ethidium bromide (EB) injection into the right side of the hippocampus area of male rats. Vitamin D3 was administered to rats for 7 and 28 days prior to behavioral experiments using Morris water maze (MWM). Travelled distance, time spent to reach the platform, and time spent in target zone, were considered for learning and spatial memory evaluation. Nitrite oxide (NO2-) concentration was measured as an indicator for nitric oxide production. The time spent to reach the platform and the travelled distance were decreased significantly by 28 days of vitamin D3 administration (compared to 7 days experiment). Time spent in target quadrant was significantly lowered by administered vitamin on day 28. Therefore, considering a number of studies that have shown the effect of vitamin D3 on cognition, these findings could support their potential effect. Besides, nitric oxide concentration significantly differed in 28 days of vitamin D3 treated group compared with the groups treated with EB or 7 days of vitamin D3.

Actitudes sexuales de acuerdo con el nivel de severidad del trauma craneoencefálico / Sexual attitudes according to the level of severity of the cranioencephalic trauma

El objetivo de esta investigación fue analizar la actitud hacia la sexualidad en pacientes con antecedentes de trauma craneoencefálico (TCE), de acuerdo al nivel de severidad presentado. Método: se llevó a cabo un estudio de tipo descriptivo en una muestra de 126 personas, con edades comprendidas entre los 18 y 49 años, con antecedente de trauma craneoencefálico leve, moderado y severo, a quienes se les aplicó la Escala de Actitudes hacia la Sexualidad Ampliada (ATSS) y una encuesta de actitudes hacia la sexualidad. Resultados: se encontró que la mayoría de los participantes manifestaron haber sufrido cambios en su sexualidad tras el TCE, caracterizados por la disminución de la frecuencia de las relaciones y el deseo sexual, sin embargo, evidencian una actitud positiva frente a la sexualidad. Conclusiones: si bien la sexualidad es considerada importante por los participantes del estudio, no se evidenció una conducta tendiente a la erotofilia. No se encontraron diferencias significativas respecto al nivel de severidad del trauma craneoencefálico

Introducción:el síndrome de Dravet, también conocido como epilepsia mioclónica grave de la infancia, corresponde a una encefalopatía epiléptica resistente a fármacos que inicia generalmente en el primer año de vida. Se caracteriza por crisis epilépticas que suelen tener múltiples desencadenantes; el más asociado es la presencia de episodios febriles previos. Se considera una enfermedad rara, debido a su baja incidencia y prevalencia. Presentación del caso: niño de 10 años de edad con un cuadro de epilepsia de origen estructural, asociada con un retraso en el neurodesarrollo y anomalías craneofaciales meno-res, con antecedente de cardiopatía congénita no corregida, colpocefalia y agenesia del cuerpo calloso. Debido a la persistencia de las crisis convulsivas y su consiguiente resistencia farmacológica, se le rea-lizó un exoma genético que evidenció una mutación del gen SCN9. Discusión: el síndrome de Dravet debe ser sospechado en todo paciente menor de un año que tenga crisis convulsivas a repetición asociadas con episodios febriles cuantificados. Aproximadamente, entre el 70 % y el 85 % de los pacientes con el diagnóstico de síndrome de Dravet presenta una mutación en el gen SCN1A, por lo que mutaciones en otros genes que codifican para canales de sodio, ubicados en el mismo cromosoma, como el SCN9A, podrían contribuir de forma multifactorial a dicha entidad

Introduction: Dravet syndrome, also known as severe myoclonic epilepsy in infancy, is a drug resistant epileptic encephalopathy that usually begins in the first year of life. It is characterized by the presence of epileptic seizures that usually have multiple triggers; the most currently associated is the presence of previous febrile episodes. It is considered as a rare disease due to its low incidence and prevalence. Case presentation: We reported the case of a ten-year-old boy with structural epilepsy associated with a neuro-developmental delay and minor craniofacial anomalies. He had a history of uncorrected congenital heart disease, colpocephaly, and agenesis of the corpus callosum. Due to the persistence of seizures secondary to drug resistance, it was decided to perform a genetic exome that evidenced a mutation of the SCN9A gene. Conclusions: Dravet syndrome should be suspected in all patients under one year of age who have recu-rrent seizures associated with fever that does not respond to medication and modifies its presentation. Approximately 70%−85% of the patients diagnosed with Dravet syndrome have a mutation in the SCN1A gene; therefore, mutations in other genes that encode sodium channels located on the same chromosome, such as SCN9A, could contribute in a multifactorial way.

Introdução: a síndrome de Dravet, também conhecida como epilepsia mioclônica grave da infância, corresponde a uma encefalopatia epiléptica resistente a medicamentos que geralmente se inicia no primeiro ano de vida. É caracterizada pela presença de crises epilépticas que costumam ter múltiplos detonantes, sendo que o mais associado atualmente é a presença de episódios febris prévios. É conside-rada uma doença rara devido à sua baixa incidência e prevalência. Apresentação do caso: é apresentado o caso de um menino de 10 anos de idade com quadro de epilepsia de origem estrutural, associada a atraso no desenvolvimento neurológico e pequenas anomalias craniofaciais; com histórico de cardio-patia congênita não corrigida, colpocefalia e agenesia do corpo caloso. Devido à persistência das crises epilépticas e consequente resistência farmacológica, optou-se pela realização de um exoma genético que apresenta uma mutação do gene SCN9. Discussão: a síndrome de Dravet deve ser suspeitada em todos os pacientes com menos de um ano de idade que apresentam convulsões repetidas associadas a episódios febris quantificados. Aproximadamente 70 a 85% dos pacientes com diagnóstico de síndrome de Dravet apresentam mutação no gene SCN1A, portanto mutações em outros genes que codificam canais de sódio, localizados no mesmo cromossomo, como o SCN9A, poderiam contribuir de forma multifatorial para essa entidade

Caracterização fenotípica das epilepsias geneticamente determinadas diagnosticadas pelo sequenciamento de nova geração / Phenotypic characterization of genetically determined epilepsies diagnosed by next-generation sequencing

Nos últimos anos, o emprego na prática clínica de painéis genéticos e do sequenciamento do exoma e do genoma permitiu o diagnóstico em pacientes sem uma etiologia definida, principalmente nas Encefalopatias Epilépticas e do Desenvolvimento (EEDs). A identificação das formas de epilepsia geneticamente determinadas permite caracterizar melhor sua história natural e orientar o tratamento, ao mesmo tempo em que propicia o aconselhamento genético. O objetivo do estudo foi descrever o fenótipo de indivíduos com epilepsia geneticamente determinada com variantes patogênicas ou provavelmente patogênicas, previamente identificadas pelo NGS. Foram incluídos pacientes até a idade de 18 anos, acompanhados por serviços de Neurologia Infantil e/ou de Genética Médica no estado do Rio de Janeiro, provenientes de hospitais públicos ou de clínicas privadas. O estudo, de natureza descritiva e transversal, foi realizado através da análise de uma amostra de conveniência. No período de abril de 2020 até dezembro de 2021, foram incluídos 75 pacientes, cujo diagnóstico etiológico foi relacionado a 53 genes diferentes. O tipo de sequenciamento de nova geração realizado foi exoma em 56 (74,6%) pacientes, painel genético em 18 (24%) e genoma em um (1,7%). Em relação ao padrão de herança dos 53 genes, 50 (67%) pacientes apresentavam variantes deletérias em genes de herança autossômica dominante (AD), dez (13%) em genes com herança autossômica recessiva (AR), 12 (16%) em genes com o padrão dominante ligado ao X (XD) e 3 (4%) em genes com herança recessiva ligada ao X (XR). O teste em trio foi realizado em 37 pacientes (49,3%) e 33 pacientes apresentaram variantes de novo. O tipo de variante mais frequente foi a missense, seguida pelas variantes frameshift, variantes em regiões de sítio de splicing, deleções in-frame e variantes nonsense. A média de idade do diagnóstico da epilepsia foi de 18 meses, variando entre o primeiro dia de vida até 12 anos. Diagnóstico de EED foi estabelecido em 97,3% pacientes (N=73), na média de idade de 3 anos e 1 mês, e 36 pacientes apresentam uma síndrome epiléptica específica, sendo as mais comuns as Síndromes de West e de Lennox-Gastaut. O padrão de herança de maior frequência no grupo estudado foi AD. Os genes mais frequentes encontrados na nossa amostra foram: genes com herança AD: SCN8A (8%), STXBP1 (8%), KCNQ2 (6,6%), KCNT1 (4%); ligada ao XD: CDKL5 (4%); PCDH19 (4%); e AR: RARS2 (2,6%). O maior número de pacientes está associado a genes que sintetizam canais iônicos voltagem-dependentes (N=19/25,3%) e os genes mais frequentes foram, sucessivamente: SCN8A, KCNQ2, KCNT1, KCNA2. Na nossa amostra, somente dois pacientes conseguiram realizar o exame pelo SUS. O tempo médio de espera para realização do NGS foi de 8 meses. O conhecimento e a interpretação dos resultados dos testes genéticos moleculares têm evoluído de maneira substancial. Disponibilizar o NGS de forma universal para pacientes com suspeita de epilepsia de origem genética, permitirá o diagnóstico de um maior número de pacientes, a identificação de casos atípicos e a adequação terapêutica.

In recent years, the use in clinical practice of genetic panels, exome and genome sequencing has allowed the diagnosis in patients without a defined etiology, mainly in epileptic and developmental encephalopathies (EED). The identification of genetically determined forms of epilepsy makes it possible to better characterize its natural history, guide treatment and provide genetic counseling. The aim of the study was to describe the phenotype of individuals with genetically determined epilepsy with pathogenic or probably pathogenic variants, previously identified by NGS. Patients up to the age of 18 years, followed by Child Neurology and/or Medical Genetics services in the State of Rio de Janeiro, from Public Hospitals or private clinics were included. The study was descriptive and transversal, through the analysis of a convenience sample. From April 2020 to December 2021, 75 patients were included, whose etiological diagnosis was related to 53 different genes. The type of next-generation sequencing performed was exome in 56 (74.6%) patients, genetic panel in 18 (24%) and 1 (1.7%) performed the genome. Regarding the inheritance pattern of the 53 genes, 50 (67%) patients had deleterious variants in genes of autosomal dominant inheritance (AD), 10 (13%) in genes with autosomal recessive inheritance (AR), 12 (16%) with dominant pattern X-linked (XD) and 3 (4%) with X-linked recessive inheritance (XR). Trio testing was performed in 37 patients (49.3%) and 33 patients have de novo variants. The most frequent type of variant was missense, followed by frameshift variants, variants in splicing site regions, in- frame and nonsense variants. The mean age of epilepsy diagnosis was 18 months, ranging from the first day of life to 12 years. Diagnosis of DEE was established in 97.3% patients (N=73), with a mean age of 3 years and 1 month and 36 patients presented a specific epileptic syndrome, the most common being West syndrome and Lennox- Gastaut. The most frequent inheritance pattern in the studied group was AD. The most frequent genes found in our sample were: genes with AD inheritance: SCN8A (8%), STXBP1 (8%), KCNQ2 (6.6%), KCNT1 (4%); XD-linked: CDKL5 (4%); PCDH19 (4%); and AR: RARS2 (2.6%). The largest number of patients is associated with genes that synthesize voltage-gated ion channels (N=19/25.3%) and the most frequent genes were successively: SCN8A, KCNQ2, KCNT1, KCNA2. In our sample, only 2 patients were able to perform the exam through the SUS. The mean waiting time for performing the NGS was 8 months. Knowledge and interpretation of molecular genetic test results have evolved substantially. Making NGS universally available in patients suspected of having epilepsy of genetic origin, will allow the diagnosis of a greater number of patients, identification of atypical cases and therapeutic adequacy.

El 85.29% (58) de los pacientes presentó Hipertensión Arterial, 39.71% (27) Diabetes Mellitus, 29.41% (20) Enfermedad Cerebrovascu- lar previa. Fallecieron 38 (55.88%) pacientes y 15 (22.06%) presentaron dependencia 90 días después del inicio de la patología. Pacientes con puntuación NIHSS mayor o igual a 16 tienen mayor riesgo relativo (R.R.) de mortalidad (R.R.: 1.91) y discapacidad (R.R.:2.74) que los pacientes que presentaron puntuación NIHSS inferior a 16. Conclusiones: Entre mayor sea el déficit neurológico al inicio de la patología, mayor es la probabilidad de fallecer o quedar con grado de discapacidad elevado...(AU)

Absceso cerebral por Nocardia sp. En un paciente inmunocompetente en el Perú: reporte de caso / Brain abscess due to Nocardia sp. In an immunocompetent patient in Peru: a case report

RESUMEN La nocardiosis cerebral es una entidad rara que ha sido reportada principalmente en inmunosuprimidos, y en la actualidad no se dispone de guías clínicas que recomienden un tratamiento de primera línea. Presentamos el caso de un adulto mayor, inmunocompetente, con cuadro de encefalopatía y hemiparesia izquierda, asociado a lesiones compatibles con absceso cerebral múltiple y sugerente de etiología infecciosa. Recibió, inicialmente, tratamiento para la tuberculosis, absceso bacteriano y toxoplasmosis, sin respuesta clínica favorable. Se inició un tratamiento empírico para la nocardiosis con meropenem y trimetoprim/sulfametoxazol, y se logró mejoría clínica e imagenológica. La ocurrencia de eventos adversos obliga el uso temporal de medicamentos alternativos. Se resaltan algunos criterios a considerar para incluir la nocardiosis en el diagnóstico diferencial en los casos de absceso cerebral múltiple y se mencionan los métodos diagnósticos de laboratorio y los fármacos para iniciar un tratamiento empírico.

ABSTRACT Cerebral nocardia infections is a rare entity, which has been mainly reported in immunosuppressed patients. Currently, there are no clinical guidelines for first-line treatment. Our case refers to an older immunocompetent adult, with encephalopathy and left hemiparesis, associated with lesions compatible with multiple brain abscess and suggestive of infectious etiology. He initially received treatment for tuberculosis, bacterial abscess, and toxoplasmosis, without a favorable clinical response. An empirical treatment for nocardiosis started, by using meropenem and trimethoprim / sulfamethoxazole, and clinical and imaging improvement was achieved. The occurrence of adverse events forces the temporary use of alternative medications. We highlight some criteria for including nocardiosis in the differential diagnosis in cases of multiple brain abscess and mention laboratory diagnostic methods and drugs to initiate empirical treatment.

Factores asociados a la mortalidad en pacientes cirróticos / Factors associated with mortality in cirrhotic patients

Introducción: La cirrosis hepática representa en Perú el 9,1 por ciento de las causas de mortalidad. Existe poca evidencia sobre la influencia de variables epidemiológicas y clínicas en la mortalidad de pacientes con cirrosis hepática en Latinoamérica, en especial en países en vías de desarrollo, como Perú. Objetivo: Identificar los factores asociados a la mortalidad en pacientes cirróticos. Métodos: Estudio trasversal en pacientes cirróticos atendidos en el Hospital Cayetano Heredia, de Piura, Perú, en el año 2017. La variable dependiente fue la mortalidad hospitalaria y las variables independientes fueron las características epidemiológicas, clínicas y de laboratorio. Se utilizó la prueba exacta de Fisher y la prueba de t para estimar los factores asociados a la mortalidad. Resultados: De 52 pacientes, la frecuencia de mortalidad debido a cirrosis fue de 35,4 por ciento. Tener ascitis moderada (p = 0,004), grado de encefalopatía (p = 0,001), leucocitosis (p = 0,004), enfermedad descompensada según índice de Child Pugh (p = 0,023), índice de Meld entre 30-39 puntos (p < 0,001) y niveles de creatinina (p = 0,009) resultaron asociados a una mayor frecuencia de mortalidad. Conclusión: La presencia de ascitis moderada, grado de encefalopatía, leucocitosis, enfermedad descompensada según índice de Child Pugh, índice de Meld entre 30-39 y los niveles de creatinina, están asociados a la mortalidad en pacientes cirróticos(AU)

Introduction: Liver cirrhosis represents 9,1 percent of causes of mortality in Peru. There is little evidence on the influence of epidemiological and clinical variables on the mortality of patients with liver cirrhosis in Latin America, especially in developing countries such as Peru. Objective: To identify the factors associated with mortality in cirrhotic patients. Methods: Cross-sectional study in cirrhotic patients treated at the Cayetano Heredia Hospital in Piura, Peru, year 2017. The dependent variable was hospital mortality and the independent variables were epidemiological, clinical and laboratory characteristics. Fisher's exact test and the T test were used to estimate the factors associated with mortality. Results: Of 52 patients, the frequency of mortality due to cirrhosis was 35,4 percent. Have moderate ascites (p = 0,004), degree of encephalopathy (p = 0,001), leukocytosis (p = 0,004), decompensated disease according to the Child Pugh index (p = 0,023), Meld index between 30-39 points (p < 0,001) and creatinine levels (p = 0,009) were associated with a higher frequency of mortality. Conclusion: The presence of moderate ascites, degree of encephalopathy, leukocytosis, decompensated disease according to the Child Pugh index, Meld index between 30-39, creatinine levels are associated with mortality in cirrhotic patients(AU)

Encefalopatía subaguda en una paciente con policondritis recidivante: caso clínico / Subacute encephalopathy associated with relapsing polychondritis: report of one case

Relapsing polychondritis (RP) is a rare multisystemic autoimmune disorder characterized by the inflammation and destruction of cartilages, with preference for auricular, nasal and laryngotracheal cartilages. RP may also affect proteoglycan-rich structures, such as, blood vessels, eyes, kidneys, and heart. The central nervous system (CNS) is involved in less than 3% of patients. We report a 32-year-old female with RP associated with a progressive subacute encephalopathy characterized by behavioral disturbances, auditory and visual hallucinations. The EEG showed generalized slow activity and a mononuclear pleocytosis with increased protein was found in the cerebrospinal fluid. The brain magnetic resonance imaging showed multiple supra and infratentorial nodular inflammatory lesions. After initiating treatment with corticosteroids and cyclophosphamide, a significant improvement in chondritis and neurological status was observed.

Características clínicas y tomográficas de pacientes con enfermedad cerebrovascular isquémica / Clinical and tomographic characteristics of patients with ischemic cerebrovascular disease

Introducción: El método clínico por sí solo no es definitivo para diagnosticar una enfermedad cerebrovascular, por lo que es importante el uso de medios de diagnóstico imagenológicos como la tomografía axial computarizada, que permite investigar los aspectos morfológicos y funcionales del cerebro. Objetivo: Describir las características clínicas y tomográficas de pacientes con infarto cerebral. Métodos: Se efectuó un estudio descriptivo y transversal de 269 pacientes con infarto cerebral, atendidos en el Hospital Provincial Docente Clinicoquirúrgico Saturnino Lora Torres de Santiago de Cuba, desde enero hasta diciembre de 2019. Resultados: Predominaron el sexo masculino (54,6 %), el grupo etario de 70-79 años, las afectaciones motoras (76,5 %), la alteración de la conciencia (51,3 %) y el trastorno del lenguaje (50,5 %). En 38 pacientes los resultados de la tomografía fueron negativos antes de las 24 horas de evolución y 64,0 % se consideraron mejorados con secuelas. Conclusiones: La tomografía antes de las 24 horas demuestra una baja positividad y los hallazgos evolucionan con el tiempo, aunque es posible reconocer varios signos precoces de ictus agudo en menos de 4-6 horas.

Introduction: The clinical method by itself is not definitive to diagnose a cerebrovascular disease, reason why the use of imaging diagnostic means, as the computerized axial tomography is important, as it allows to investigate the morphological and functional aspects of the brain. Objective: To describe the clinical and tomographic characteristics of patients with complete stroke. Methods: A descriptive and cross-sectional study of 269 patients with complete stroke, assisted in Saturnino Lora Torres Teaching Clinical Surgical Provincial Hospital was carried out in Santiago de Cuba, from January to December, 2019. Results: There was a prevalence of the male sex (54.6 %), 70-79 age group, motor disorders (76.5 %), alteration of the conscience (51.3 %) and language disorder (50.5 %). In 38 patients the results of the tomography were negative before the 24 hours of clinical course and 64.0 % were better with aftereffects of the disease. Conclusions: Tomography before the 24 hours demonstrates a low positivity and findings have a favorable clinical course as time goes by, although it is possible to recognize several early signs of acute ictus in less than 4-6 hours.
