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.

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.

Mutación en el gen SCN9Aasociado con el síndrome de Dravet: presentación de un caso pediátrico / Mutation in the SCN9A Gene Associated with Dravet Syndrome: A Pediatric Case Report / Mutação no gene SCN9A associada à síndrome de Dravet: relato de um caso pediátrico

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

Imaging features of 10 patients with toxic encephalopathy caused by diquat / 中华劳动卫生职业病杂志

Objective: To explore the CT and MRI imaging findings of diquat toxic encephalopathy. Methods: CT and MRI imaging features of 10 patients with diquat poisoning encephalopathy who had been clinically diagnosed were retrospectively reviewed. Results: CT was performed in all 10 patients, and MRI was performed in 8 patients. In 10 patients, 7 had positive signs on CT, and 8 patients with MRI examination had abnormal changes in the images. The main CT findings were symmetrical hypodensity in bilateral cerebellar hemisphere, brainstem, thalamus and basal ganglia, and swelling of brain tissue. The main MRI findings were symmetrical lesions and brain edema in the deep nuclei of cerebellar hemisphere, brainstem, thalamus and basal ganglia, low signal on T1WI, high signal on T2WI and T2-FLAIR, and cytotoxic edema on diffusion weighted imaging (DWI) . On review after treatment, both CT and MRI showed resorption of the lesion, which narrowed in size. Conclusion: The imaging findings of diquat poisoning encephalopathy are characteristic and the location of the lesion is characteristic, and CT and MRI have a certain diagnostic value in diquat poisoning encephalopathy, which is important for clinical 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.

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)

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.

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.

Encefalopatia reversível induzida por contraste após embolização com espiras por epistaxe / Reversible contrast-induced encephalopathy after coil embolization of epistaxis

RESUMO Uma mulher com 37 anos de idade, gestante de 35 semanas, foi admitida em um hospital local em razão de epistaxe grave, que resultou em choque e em necessidade de realização de cesárea emergencial. Após falha do tamponamento para controlar a hemorragia, decidiu-se por tratamento angiográfico. Após o procedimento, ela foi admitida à unidade de terapia intensiva neurocrítica, encontrando-se confusa e agitada, com necessidade de sedação e intubação orotraqueal. Na unidade de terapia intensiva, as investigações incluíram exames de ressonância magnética, punção lombar com painel viral, eletroencefalograma, testes para autoimunidade e avaliações hidroeletrolítica e metabólica. O exame de ressonância magnética mostrou área puntiforme restrita na corona radiata esquerda nas sequências de imagens pesadas em difusão, além de leve edema cortical posterior (sem restrição à difusão), e o eletroencefalograma mostrou atividade lenta difusa moderada, atividade frontoparietal lenta e escassos componentes paroxísticos associados no hemisfério esquerdo. Outros exames não mostraram alterações relevantes. Por causa da relação temporal e da história clínica, assim como imagens de ressonância magnética, formulou-se o diagnóstico de encefalopatia induzida por contraste. A sedação foi retirada após 2 dias na unidade de terapia intensiva, e a paciente foi extubada, verificando-se completa recuperação neurológica dentro das 24 horas seguintes.

ABSTRACT A 37-year-old woman (35 weeks pregnant) was admitted to a local hospital due to severe epistaxis resulting in shock and the need for emergency cesarean section. After failure to tamponade the bleeding, angiographic treatment was provided. After the procedure, she was admitted to the neurocritical intensive care unit and was confused and agitated, requiring sedation and endotracheal intubation. In the intensive care unit, diagnostic investigations included brain magnetic resonance imaging, lumbar puncture with viral panel, electroencephalogram, tests for autoimmunity, and hydroelectrolytic and metabolic evaluations. Magnetic resonance imaging showed a puntiform restricted diffusion area on the left corona radiata on diffusion weighted imaging and mild cortical posterior edema (without restricted diffusion), and an electroencephalogram showed moderate diffuse slow activity and fronto-temporal slow activity of the left hemisphere with associated scarce paroxysmal components. The other exams did not show any relevant alterations. Due to the temporal relationship, the clinical history and the magnetic resonance imaging results, a diagnosis of contrast-induced encephalopathy was made. After 2 days in the intensive care unit, sedation was withdrawn, the patient was extubated, and total neurological recovery was verified within the next 24 hours.

El objetivo fue evaluar la encefalitis asociada a la gripe y destacar diferentes manifestaciones neurológicas y cambios de neuroimagenología. El estudio incluyó a 13 pacientes. Los síntomas neurológicos ocurrieron tras los síntomas típicos de la gripe. Los cambios de neuroimagenología incluyen alteraciones de señal de la sustancia blanca cortical y subcortical, edema localizado o generalizado y lesiones multifocales simétricas bilaterales en el tálamo y la médula del cerebelo. Las opciones terapéuticas incluyen metilprednisolona en inyección intravenosa, inmunoglobulina intravenosa, plasmaféresis y oseltamivir. Es fundamental considerar la encefalitis asociada a la gripe en pacientes con convulsiones, la encefalopatía con hallazgos radiológicos compatibles, e iniciar el tratamiento lo antes posible

Influenza is mostly associated with the respiratory tract system, especially in the winter season. Various neurological complications could occur due to influenza infection. Pediatric patients who had severe neurological manifestations due to influenza infection from September 2018 to February 2019 were evaluated for clinical characteristics, neuroimaging studies, treatment, and outcome. We aimed to assess Influenza-associated encephalitis in children, emphasize different neurological manifestations and neuroimaging changes. Thirteen patients were included in the study. Neurological symptoms occurred after flu-like symptoms. Neuroimaging changes of influenza-associated encephalitis/encephalopathy include cortical and subcortical white matter signal alterations, localized or generalized edema, and bilateral symmetrical multifocal lesions on the thalamus and cerebellar medulla. Pulse methylprednisolone, intravenous immunoglobulin, plasma exchange, and oseltamivir are the therapy choices. It is essential to consider influenza-associated encephalitis in patients with seizures, encephalopathy with supporting radiological findings, especially during the influenza season and starting treatment as fast as possible for better outcomes.

Prosper Menière: the man who located vertigo in the inner ear / Prosper Menière: o homem que localizou a vertigem na orelha interna

ABSTRACT Since the Greek Aellus Galenum (129 AD - c.200/c.216), vertigo was considered a problem attributed to a cerebral disorder, diagnosed as the manifestation of apoplectiform cerebral congestion. In the mid-19th century, the Frenchman Prosper Menière changed this concept by placing the origin of this symptom in the inner ear. The main objective of this historical note is to highlight who Menière was, his work, and some aspects of the disease that bears his name.

RESUMO Desde o grego Aellus Galenum (129 d.C. - c.200/c.216), a vertigem era considerada um problema atribuído a um distúrbio cerebral, diagnosticado como a manifestação de uma 'congestão cerebral apoplectiforme'. Em meados do século 19, o francês Prosper Menière mudou esse conceito, colocando a origem desse sintoma na orelha interna. O principal objetivo desta nota histórica é ressaltar quem foi Menière, seu trabalho e alguns aspectos da doença que leva seu nome.

El cannabidiol y sus indicaciones en psiquiatría / Cannabidiol and its indications in psychiatry / Canabidiol e suas indicações em psiquiatria

Esta revisión abarca la historia, el origen, la síntesis biológica del cannabidiol (CBD), su interacción con el sistema de cannabinoides endógenos, las presentaciones para uso clínico, su farmacocinética, tolerabilidad y la evidencia actual de los usos en psiquiatría. Además del origen de su nombre y las precisiones de la taxonomía botánica de la cannabis, es de interés conocer a partir de estudios de polen fósil la cronología y ruta que siguió ancestralmente hasta la llegada a Europa y cómo allí se inició su estudio con la idea de introducirla en la farmacopea del momento y como modelo de estudio de trastornos cerebrales como las psicosis. Jacques Joseph Moreau de Tours (1804-1884), psiquiatra francés, la usó en forma de hachís y propició el consumo experimental por intelectuales de la época. Basado en la presunción de que intelectuales e individuos con una educación eran sujetos de estudio que podían proveer relatos más detallados y floridos de las experiencias vividas bajo sus efectos, Moreau de Tours concibió por primera vez que los efectos de la cannabis eran un paradigma experimental para el estudio de las psicosis. Luego experimentó su uso terapéutico con resultados negativos. En el caso del CBD, extraído de la cannabis, la psiquiatría contemporánea podría vislumbrar resultados más promisorios a través de la investigación clínica en diferentes indicaciones

This review covers the history, origin, and biological synthesis of Cannabidiol (CBD), together with its interaction with the endogenous cannabinoid system, its options for clinical use, its pharmacokinetics, its tolerability, and current evidence for indications in psychiatry. In addition to the origin of its name and the details of the botanical taxonomy of cannabis, it is a matter of interest to review fossil pollen studies to help us trace the chronology and route that it followed until it got to be known in Europe, and how was included in the pharmacological studies of the time, with the aim to use it as a model for studying brain disorders such as psychoses. French psychiatrist Jacques Joseph Moreau de Tours (1804-1884) used it in the form of hashish and encouraged its experimental consumption by intellectuals and famous artists of the time, who were then asked to provide detailed descriptions of their experiences under the effects of cannabis. Moreau de Tours was the first to conceive that the effects of cannabis were an experimental paradigm for the study of psychoses. He went on to experiment its therapeutic use with negative results. In the case of CBD, extracted from cannabis, contemporary psychiatry could foresee more promising results in its therapeutic effects through clinical research in different indications.

Esta revisão cobre a história, origem, síntese biológica do canabidiol (CBD), sua interação com o sistema canabinoide endógeno, apresentações para uso clínico, sua farmacocinética, tolerabilidade e evidências atuais de uso em psiquiatria. Além da origem do seu nome e dos detalhes da taxonomia botânica da cannabis, é interessante saber pelos estudos do pólen fóssil a cronologia e o percurso que ele percorreu ancestralmente até chegar à Europa e como começou seu estudo com a ideia lá para introduzi-lo na farmacopeia do momento e como um modelo para estudar distúrbios cerebrais como as psicoses. Jacques Joseph Moreau de Tours (1804-1884), psiquiatra francês, utilizou-o na forma de haxixe e estimulou o consumo experimental pelos intelectuais da época. Com base na suposição de que intelectuais e indivíduos educados eram sujeitos de estudo que poderiam fornecer relatos mais detalhados e floreados de experiências sob sua influência, Moreau de Tours primeiro concebeu que os efeitos da cannabis eram um paradigma experimental para o estudo das psicoses. Ele então experimentou seu uso terapêutico com resultados negativos. No caso do CBD, extraído da cannabis, a psiquiatria contemporânea poderia ver resultados mais promissores por meio de pesquisas clínicas em diferentes indicações.

A propósito de complicaciones infrecuentes de enfermedades comunes. Síndrome de Ekiri / About Infrequent complications of common diseases: Ekiri Syndrome

Resumen La infección por enterobacterias desencadena usualmente síntomas gastrointestinales caracterizados por vómito, diarrea y dolor abdominal, de severidad y curso variable. El compromiso extraintestinal esta descrito, inclusive sin las manifestaciones gastrointestinales clásicas lo que favorece diagnósticos y tratamientos tardíos pudiendo llegar a ser incapacitantes y letales. El síndrome de Ekiri, también denominado síndrome de encefalopatía letal tóxico, se caracteriza por una disfunción aguda del sistema nervioso central secundaria a infección por enterobacterias las cuales favorecen el desarrollo de microtrombos a nivel cerebral con inflamación mediada por el factor de necrosis tumoral α e IL- 1β y disfunción de la barrera hematoencefálica con una alta tasa de mortalidad. Dentro de nuestro conocimiento, presentamos el primer caso reportado en Colombia sobre el síndrome de Ekiri.

Abstract Gastrointestinal infection usually manifests with nausea, vomit and abdominal pain, all of them wit course and variable severity. Extrainstestinal compromise is described, even without gastrointestinal symptoms, what causes a delay on diagnosis and treatment, worsening the prognosis. Ekiri syndrome, also known as lethal toxic encephalopathy is characterized by an acute neurological dysfunction secondary to enterobacterial infection which favor thrombi development and local inflammation mediated by tumor necrosis factor alpha and IL-1β with blood brain barrier dysfunction and high mortality. As we know, we present the first Ekiri syndrome case reported in Colombia.

Síndrome de Susac: reporte del primer caso en Honduras / Susac Syndrome: Report of the first case in Honduras

El síndrome de Susac es una entidad rara, descrito como una tríada clínica de encefalopatía, sordera neurosensorial y trastorno visual por oclusión de ramas de arteria retiniana, aunque no siempre se presenta como tríada, se carac- teriza por evolución prolongada y no necesariamente secuencial ni correlacionada con la presentación clínica, que es variable, por lo que el diagnóstico puede ser tardío e influenciar el pronóstico. Es más frecuente en mujeres. La patogénesis se considera como una enfermedad microangiopática autoinmune a nivel cerebral, retiniana y coclear. Descripción del caso clínico: Se presenta caso de paciente masculino de 36 años, con cuadro de cefalea, cambios conductuales, déficit motor y sensitivo de hemicuerpo derecho, seguido por alteraciones visuales y disminución de per- cepción auditiva. Se realiza diagnóstico con imagen de resonancia magnética cerebral con lesiones redondeadas hiperintensas en cuerpo calloso y regiones cortico-subcorticales; audiometría con sordera neurosensorial; y angiografía con fluoresceína de retina con obstrucción de arteria retiniana, confirmando este último recur- so el diagnóstico de síndrome de Susac. Conclusiones: Esta es una enfermedad probablemente subdiagnosticada que debe ser contemplada en el diagnóstico diferencial de enfermedades vas- culares cerebrales o desmielinizantes e implica importantes com- plicaciones y secuela sobre el paciente, el diagnóstico temprano influencia el pronóstico, por lo que debe establecerse tratamiento agresivo y temprano a fin de minimizar daños...(AU)
