Diagnóstico por imágenes de un síndrome de Wernicke Korsakoff con estigmas de Marchiafava-Bignami / maging diagnosis of Wernicke - Korsakoff syndrome with Marchiafava-Bignami stigmat

Las enfermedades de Marchiafava-Bignami y de Wernicke Korsakoff, se consideran complicaciones neuropsiquiátricas causadas por el consumo crónico de bebidas alcohólicas. Son encefalopatías poco frecuentes caracterizadas por una desmielinización y necrosis del cuerpo calloso, con la subsiguiente atrofia por daño en las partes bajas del cerebro (tálamo e hipotálamo). Se presenta un paciente masculino de 29 años, con antecedentes de alcoholismo, el cual acude a consulta de Oftalmología por presentar disminución de la visión del ojo derecho durante un año. Se le realizaron, tomografía simple y resonancia magnética con contraste endovenoso de cráneo, donde se observaron hallazgos radiológicos compatibles con el síndrome de Wernicke Korsakoff (ocasiona afectación de la memoria y el aprendizaje) con estigmas de Marchiafava-Bignami (enfermedad poco conocida). Es necesario el dominio de la epistemología de estas enfermedades, porque, a pesar del mal pronóstico en su forma aguda, se reportan casos con buena evolución, si se le realiza un diagnóstico y tratamiento oportunos.

Marchiafava-Bignami and Wernicke-Korsakoff diseases are considered neuropsychiatric complications caused by the chronic consumption of alcoholic beverages. They are rare encephalopathies characterized by demyelination and necrosis of the corpus callosum, with subsequent atrophy due to damage in the lower parts of the brain (thalamus and hypothalamus). We present a 29-year-old male patient with a history of alcoholism who went to the Ophthalmology consultation due to decreased vision in his right eye for a year. Simple tomography and magnetic resonance imaging with intravenous contrast of the skull were performed, observing radiological findings of Wernicke -Korsakoff syndrome (affect memory and learning) with Marchiafava-Bignami stigmata (little-known disease). Mastery of the epistemology of these diseases is necessary, because, despite the poor prognosis in its acute form, cases with good evolution are reported, if an opportune diagnosis and treatment is made.

Wernicke-Korsakoff Syndrome associated with hyperemesis gravidarum and fetal death: Case report and literature review / Síndrome de Wernicke-Korsakoff associado a hiperêmese gravídica e morte fetal: Relato de caso e revisão de literatura

We describe a clinical case of a pregnant patient with hyperemesis gravidarum who progressed to abortion, Wernicke's encephalopathy, and Korsakoff's psychosis, all related to thiamine deficiency. The patient presented symptoms of disorientation, nonspecific limb movements, and fever, initially treated with metronidazole and ceftriaxone for suspected infected abortion. Subsequently, the patient was diagnosed with retained and infected abortion, and thiamine replacement therapy was initiated with an intravenous loading dose of 900 mg/day. During hospitalization, the patient presented with tetraparesis, nystagmus, decreased level of consciousness, anterograde and retrograde amnesia, confabulation, and aphasia. Magnetic resonance imaging showed lesions in the pons, typical of Wernicke's encephalopathy. The patient was empirically treated with acyclovir and ampicillin and showed clinical improvement. The text also provides a brief narrative review of the literature on the topic.

Descrevemos um caso clínico de uma paciente grávida com hiperêmese gravídica que evoluiu para aborto, Encefalopatia de Wernicke e Psicose de Korsakoff, ambas relacionadas à deficiência de tiamina. A paciente apresentou sintomas de desorientação, movimentos inespecíficos dos membros e febre, sendo, inicialmente, tratada com metronidazol e ceftriaxona por suspeita de aborto infectado. Posteriormente, a paciente foi diagnosticada com aborto retido e infectado e iniciou-se a reposição de tiamina com dose endovenosa de ataque de 900 mg/dia. Durante o internamento, a paciente apresentou tetraparesia, nistagmo, rebaixamento do nível de consciência, amnésia anterógrada e retrógrada, confabulação e afasia. A ressonância magnética mostrou lesões na ponte, típicas da Encefalopatia de Wernicke. A paciente foi tratada com aciclovir e ampicilina empiricamente e apresentou melhoras no quadro clínico. O texto também faz uma breve revisão narrativa da literatura sobre o tema.

Encefalopatía de Wernicke como complicación de la hiperemesis gravídica / Wernicke's encephalopathy as complication of hyperemesis gravidarum

RESUMEN Introducción: La hiperemesis gravídica provoca complicaciones neurológicas potencialmente letales como la encefalopatía de Wernicke, enfermedad aguda debida a la deficiencia de vitamina B1 en el cerebro. Objetivo: Presentar un caso clínico inusual de encefalopatía de Wernicke, como complicación de la hiperemesis gravídica. Caso clínico: Paciente de 42 años de edad y gestación de 12,4 semanas que ingresó por hiperemesis gravídica y luego se trasladó a la unidad de cuidados intensivos. Se solicitó valoración por Neurología al referir mareos, visión borrosa e incoordinación de los movimientos. Al examen físico presentó somnolencia, bradipsiquia, desorientación en tiempo y espacio, nistagmo horizontal y rotatorio bilateral, y ataxia del tronco. La resonancia magnética mostró hiperintensidad de señales en el tálamo, alrededor del III ventrículo, en el fórnix, corteza y subcorteza cerebral. Se planteó una encefalopatía de Wernicke secundaria a hiperemesis gravídica. La paciente evolucionó de forma favorable con la administración de vitamina B1 y esteroides. Conclusiones: La asociación entre hiperemesis gravídica y encefalopatía de Wernicke es poco frecuente, pero de consecuencias graves. El diagnóstico y el tratamiento oportuno son fundamentales para la disminución del riesgo de secuelas.

ABSTRACT Introduction: Hyperemesis gravidarum causes potentially lethal neurological complications such as Wernicke's encephalopathy, an acute disease due to vitamin B1 deficiency in the brain. Objective: To present an unusual clinical case of Wernicke encephalopathy, as a complication of hyperemesis gravidarum. Clinical case: 42-year-old patient with a 12.4-week gestation who was admitted for hyperemesis gravidarum and later transferred to the intensive care unit. Neurology assessment was requested when referring to dizziness, blurred vision and incoordination of movements. On physical examination, she presented drowsiness, bradypsychia, disorientation in time and space, bilateral horizontal and rotatory nystagmus, and trunk ataxia. Magnetic resonance imaging showed hyperintensity of signals in the thalamus, around the third ventricle, in the fornix, cortex and cerebral subcortex. Wernicke encephalopathy secondary to hyperemesis gravidarum was considered. The patient evolved favorably with the administration of vitamin B1 and steroids. Conclusions: The association between hyperemesis gravidarum and Wernicke encephalopathy is rare, but with serious consequences. Prompt diagnosis and treatment are essential to reduce the risk of sequelae.

Síndrome de Wernicke-Korsakoff em paciente gestante de 18 anos / Wernicke-Korsakoff syndrome in an 18-year-old pregnant patient

A síndrome de Wernicke-Korsakoff é uma rara encefalopatia desencadeada pela deficiência de tiamina, uma vitamina do complexo B, que atua como importante cofator de enzimas responsáveis pela manutenção da homeostase da energia cerebral. Apresentamos o caso de uma paciente de 18 anos, gestante, com diagnóstico prévio de pancreatite aguda biliar, que evoluiu à hiperêmese gravídica e à Wernicke-Korsakoff. Objetivamos, com este trabalho, chamar a atenção para a importância do diagnóstico imediato dessa síndrome diante de seu potencial em causar danos cerebrais irreversíveis, caso não tratada precocemente.

Wernicke-Korsakoff syndrome is a rare encephalopathy triggered by deficiency of thiamine, a B-complex vitamin, which acts as an important cofactor of enzymes responsible for maintaining brain energy homeostasis. We present the case of an 18-year-old pregnant woman with previous diagnosis of acute biliary pancreatitis, who developed hyperemesis gravidarum and Wernicke-Korsakoff. With this work, we aim to draw attention to the importance of the immediate diagnosis of this syndrome in view of its potential to cause irreversible brain damage if not treated early.

Wernicke encephalopathy as a complication of hyperemesis gravidarum: case report / Encefalopatia de Wernicke como complicação de hiperêmese gravídica: relato de caso

Abstract Wernicke encephalopathy (WE) is an acute neurological disorder resulting from vitamin B1 deficiency, which is common in chronic alcoholism. We report a rare case of WE due to hyperemesis gravidarum in a 25-year-old pregnant patient at 13 weeks and 5 days of gestation. Initially, the disease manifested as weakness, mental confusion, anterograde amnesia, and visual and auditory hallucinations. The diagnosis was established after the detection of suggestive findings of WE in the thalamus by magnetic resonance imaging (MRI) and a rapid improvement in the patient's clinical status subsequent to treatment with thiamine. Hyperemesis is a rare cause of WE, which makes the reported case important in the literature and reinforces the need for attention in clinical practice to rare but important complications of this common condition (hyperemesis gravidarum).

Resumo A encefalopatia de Wernicke (EW) é uma condição neurológica aguda resultada da deficiência de vitamina B1, muito comum em etilistas crônicos. Relatamos um caso de EW secundário a um quadro de hiperêmese gravídica em uma gestante de 25 anos de idade e 13 semanas e 5 dias de idade gestacional. Inicialmente essa desordem se manifestou como fraqueza, confusão mental, amnésia anterógrada, e alucinações auditivas e visuais. O diagnóstico foi estabelecido depois da detecção de achados sugestivos de EW na ressonância nuclear magnética e da melhora do quadro clínico com reposição de tiamina. A hiperêmese gravídica não é uma causa comum de EW, o que faz com que o presente relato de caso tenha importância na literatura e reforça a necessidade de atenção na prática clínica para complicações raras mas importantes desse quadro tão comum (hiperêmese gravídica).

Coma irreversível em paciente portadora de esquizofrenia paranóide: encefalopatia de Wernicke após síndrome de realimentação: um relato de caso / Irreversible coma in a patient with paranoid schizophrenia: Wernicke encephalopathy after refeeding syndrome: a case report

Encefalopatia de Wernicke (EW) e síndrome de realimentação (SR) são duas condições frequentemente coexistentes, subdiagnosticadas e que podem implicar prognóstico reservado após sua instalação. Sua identificação precoce representa um desafio para os intensivistas, haja vista a falta de sensibilidade e especificidade das manifestações clínicas. Apresenta-se um relato de caso de uma paciente portadora de esquizofrenia paranoide, sem histórico de abuso de álcool, que desenvolveu quadro de coma irreversível após greve de fome, sendo feito diagnóstico tardio de EW associada a SR. Descreve-se a evolução clínica e neuropsiquiátrica com o intuito de enfatizar a necessidade crucial de alta suspeição diagnóstica, com reposição vitamínica imediata, vigilância de distúrbios eletrolíticos e progressão parcimoniosa do aporte nutricional. (AU)

Wernicke encephalopathy (WE) and refeeding syndrome (RFS) are two often coexisting, underdiagnosed conditions that may involve a poor prognosis after their onset. Early identification represents a challenge for intensivists, given the lack of sensitivity and specificity of clinical manifestations. We report a case of a patient with paranoid schizophrenia, without a history of alcohol abuse, who developed irreversible coma after a hunger strike, with a late diagnosis of WE associated with RFS. The clinical and neuropsychiatric outcomes are described herein in order to emphasize the crucial need for a high diagnostic suspicion, with immediate vitamin replacement, monitoring of electrolyte disorders, and gradual progression of nutritional support.

Encefalopatía de Wernicke en paciente no alcohólica. A propósito de un caso / Wernicke's encephalopathy in a non-alcoholic patient. About a case

RESUMEN La encefalopatía de Wernicke es un trastorno neurológico agudo y reversible debido a la deficiencia de tiamina. El alcoholismo crónico fue la causa principal en el pasado. Actualmente, existen muchas otras situaciones que favorecen esta afección: alimentación intravenosa prolongada, hiperémesis gravídica, anorexia nerviosa, enteritis regional, síndrome de malabsorción, hemodiálisis, diálisis peritoneal, cirugía abdominal y vómitos excesivos. Esta última causa fue precisamente la que llevó a la aparición de esta patología en una paciente de 31 años.Ella acude al Hospital Provincial de Cienfuegos con cuadro clínico de vómitos de más de un mes de duración, pérdida de peso y dolor abdominal, motivo por el cual fue intervenida quirúrgicamente donde se encontró plastrón yeyunal secundario a microperforación. Luego de su recuperación, se ingresa nuevamente 11 días después con cuadro de ataxia, desviación del ojo derecho hacia ángulo nasal por parálisis del VI par craneal y confusión mental. Se piensa prieramente en un Síndrome de Guillain Barré y, al realizarse una Resonancia Magnética Nuclear de cráneo, se prescribe la presencia de lesiones hipointensas relacionadas con la presencia de una Encefalopatía de Wernicke.

ABSTRACT Wernicke's encephalopathy is an acute and reversible neurological disorder due to thiamine deficiency. Chronic alcoholism was its cause in the past. Currently, there are many other conditions which favor this condition: prolonged intravenous feeding, hyperemesis gravidarum, anorexia nervosa, regional enteritis, malabsorption syndrome, hemodialysis, peritoneal dialysis, abdominal surgery and excessive vomiting. This last cause precisely led to the appearance of this pathology in a 31-year-old patient who went to the Provincial Hospital of Cienfuegos due to having repeated vomitings for more than a month, weight loss and abdominal pain, reason for which had a surgery where jejunal plastron secondary to microperforation was found.After recovery, she is admitted again 11 days later with ataxia, deviation of the right eye towards the nasal angle due to paralysis of the VI cranial nerve and mental confusion. Initially a Guillain Barré Syndrome is suspected but when performing a Skull Nuclear Magnetic Resonance, the presence of hypointense lesions leads to the diagnosis of Wernicke's Encephalopathy.

Cuidados de enfermagem a um paciente alcoolista portador da síndrome de Wernicke-Korsakoff: estudo de caso / Cuidados de enfermería a paciente alcohólico con síndrome de Wernicke-Korsakoff: presentación de um caso / Nursing care approach towards an alcoholic patient bearing the Wernicke-Korsakoff syndrome: case study

Introduction: Wernicke-Korsakoff Syndrome (WKS) is one of the most serious consequences of alcohol abuse. The cognitive impact of the pathology is derived from alcoholic neurotoxicity and thiamine deficiency, which can progress to stupor, coma and death. Objective: Performing a case study regarding an alcoholic patient bearing the WKS, and also designing a nursing care plan. Methods: It is a case study with a qualitative approach that assesses an alcoholic patient bearing the WKS. The study was performed at the Hospital Universitário Oswaldo Cruz (HUOC) in Recife, Brazil, over the period from February to March 2016. Results: We were able to identify 14 nursing diagnoses, as follows: chronic confusion/memory deficit/disturbed thought processes/ impaired verbal communication; impaired walking/risk of tumble down; self-care deficit; nutrition smaller than the needs/fatigue; excessive fluid volume/impaired tissue integrity; bleeding risk; impaired skin integrity; ineffective tissue perfusion. Conclusion: The nursing professionals have singular importance with regards to both the execution of health education actions as well as the alcoholics' treatment, thus preventing the complications of the disease

Encefalopatía de Wernicke secundario a hiperémesis gravídica: la importancia del diagnóstico temprano / Wernicke encephalopathy secondary to hyperemesis gravidarum: importance of early diagnosis

RESUMEN Introducción: La hiperémesis gravídica (HG) es una condición frecuente en el embarazo, que puede resultar en complicaciones potencialmente letales como la encefalopatía de Wernicke (EW), síndrome que al ser reconocido y tratado tardíamente puede traducirse en una alta morbi-mortalidad materna y fetal. Objetivo: Describir el primer caso de EW secundario a HG en Colombia y realizar una revisión de la literatura publicada sobre su diagnóstico y tratamiento. Materiales y métodos: Se describe un caso de EW secundario a HG en el que se brindó un manejo interdisciplinario. Se realizó una revisión de la literatura con los términos "encefalopatía de Wernicke", "hiperémesis gravídica" y "embarazo" incluyendo reportes de casos, series de casos, artículos de revisión, investigaciones originales o cartas al editor en inglés, español y francés, en donde se analizaron el método y tiempo del diagnóstico, pauta de tratamiento y estado funcional final. Resultados: Se incluyeron 69 publicaciones y se identificaron 89 casos. En 23 de ellos se presentó pérdida gestacional, sólo en el 12,4% de los casos se reportó el nivel de tiamina, de los cuales en el 90% se encontraba disminuido y de los casos en donde se reportó estado funcional final en el 5,9% la gestante falleció. Conclusión: La EW secundaria a HG es una complicación potencialmente letal. Debe sospecharse ante cualquier alteración neurológica e historia de emesis persistente. El diagnóstico y tratamiento oportuno interdisciplinario son fundamentales para disminuir el riesgo de secuelas que limitan la capacidad funcional con alto impacto en la calidad de vida.

ABSTRACT Introduction: Hyperemesis gravidarum (HG) is a frequent condition in pregnancy, which can result in potentially lethal complications such as Wernicke encephalopathy (WE), a syndrome that can be translated into a high maternal and fetal morbidity and mortality if it is recognized and treated late. Objective: To describe the first case of WE due to HG in Colombia and to review the published literature about its diagnosis and treatment. Materials and methods: We describe a case of WE due to HG with an interdisciplinary approach. A review of the literature was performed with the terms "Wernicke's encephalopathy", "hyperemesis gravidarum" and "pregnancy" including case reports, case series, review articles, original investigations or letters to the editor in English, Spanish and French, where the method and time of the diagnosis, treatment regimen and sequelae were analyzed. Results: Sixty-nine publications were included and 89 cases were identified. In 23 of them had a gestational loss, only in 12.4% of the cases the thiamine level was reported, in which 90% was diminished and in the cases where the final functional status was reported in 5.9% of the pregnant woman died. Conclusion: WE due to HG is a potentially lethal complication. In any neurological disturbance and history of persistent emesis it should be suspected. Timely interdisciplinary diagnosis and treatment are essential to reduce the risk of sequelae that limit functional capacity with a high impact on quality of life.

Presentación del síndrome de Wernicke-Korsakoff secundario a encefalitis por citomegalovirus, a propósito de un caso / Wernicke-Korsakoff syndrome secondary to cytomegalovirus encephalitis: A case report

Resumen El citomegalovirus (CMV) es uno de los microorganismos oportunistas con mayor prevalencia en pacientes inmunocomprometidos, aunque su reactivación ha descendido después de la introducción de la terapia antirretroviral altamente activa (Highly Active Antiretroviral Therapy, HAART). En las coinfecciones, la encefalitis se ha reportado como una de las condiciones más frecuentes. Se presenta el caso de un paciente adulto joven con infección por virus de la inmunodeficiencia humana (HIV) que tuvo un rápido deterioro neurológico evidenciado en síntomas y signos clínicos clásicos del síndrome de Wernicke-Korsakoff y que no presentaba factores de riesgo para deficiencia de tiamina. En las imágenes de la resonancia magnética cerebral, se detectaron hallazgos típicos del síndrome, y se identificó citomegalovirus (CMV) en el líquido cefalorraquídeo. Con el tratamiento específico para el CMV, se logró el control de los síntomas, aunque hubo secuelas neurológicas que mejoraron. Este es uno de los pocos casos reportados a nivel mundial de síndrome de Wernicke secundario a encefalitis por citomegalovirus.

Abstract Cytomegalovirus (CMV) is one of the opportunistic microorganisms with the highest prevalence in immunocompromised patients. Reactivation has decreased after the introduction of highly active antiretroviral therapy (HAART). Encephalitis has been reported in the coinfection as one of the most frequent presentations. We present the case of a young adult patient with HIV infection and rapid neurological deterioration due to classic clinical symptoms and signs of the Wernicke-Korsakoff syndrome, with no risk factors for thiamine deficiency, with images by nuclear magnetic resonance typical of the syndrome, and identification of cytomegalovirus in cerebrospinal fluid. The specific treatment for CMV managed to control the symptoms with neurological sequelae in progression towards improvement. This is one of the few cases reported in the literature of Wernicke syndrome secondary to cytomegalovirus encephalitis.

Encefalopatía de Wernicke en gestante con hiperemesis gravídica grave / Wernicke's encephalopathy associated with gravidarum hypermesis

Resumen ANTECEDENTES: la encefalopatía de Wernicke se origina por el déficit de vitamina B1 y sus características sobresalientes son: triada de confusión, ataxia y oftalmoplejia. Cuando hay déficit de memoria o aprendizaje se denomina síndrome de Wernicke-Korsakoff. CASO CLÍNICO: se comunica el caso de una paciente en su primer embarazo, de 18 semanas de gestación, con varios ingresos al hospital por hiperemesis gravídica; acudió al servicio de Urgencias por un cuadro de pérdida progresiva de fuerza en las extremidades inferiores. A los cinco días del ingreso tuvo empeoramiento del estado general. A la exploración física se identificó nistagmus horizonto-rotatorio, bilateral, espontáneo, tetraparesia flácida de predominio proximal, con arreflexia global de predominio en EEII y pérdida de tono de los esfínteres. La paciente se encontraba confusa, desorientada y repetitiva en su discurso. Se inició tratamiento con tiamina parenteral, por sospecha de polineuropatía metabólica por déficit de tiamina; el nistagmus y el cuadro de confusión disminuyeron. Un mes más tarde se programó para tratamiento intensivo de rehabilitación. La evolución del embarazo trascurrió con normalidad y continuó en tratamiento con tiamina y antieméticos, con estabilidad y control del cuadro. CONCLUSIÓN: la encefalopatía de Wernicke es una padecimiento de frecuencia excepcional, pero de consecuencias muy graves; de ahí la importancia de tenerlo en mente en pacientes embarazadas susceptibles de padecerlo y poner en práctica las medidas de profilaxis adecuada que eviten su aparición y las secuelas.

Abstract BACKGROUND: Wernicke's encephalopathy, caused by vitamin B1 deficiency, is characterised by the triad of confusion, ataxia and ophthalmoplegia. If memory or learning deficits appear simultaneously, it is known as Wernicke-Korsakoff syndrome. CLINICAL CASE: We present the case of a primigravida in her 18th week of pregnancy who had been suffering from hyperemesis gravidarum. She came to the emergency unit because of progressive loss of strength in her lower limbs. Five days after her admission, a deterioration of her general condition was observed. The examination revealed bilateral spontaneous horizontal-rotatory nystagmus, flaccid tetraparesis with proximal predominance, global areflexia predominantly in the lower limbs and loss of sphincters tone. The patient was confused, disoriented and repetitive in her speech. Parenteral vitamin B1 was initiated as a metabolic polineuropathy due to thiamine insufficiency was suspected. As a result the symptoms of nystagmus and confusion subsided. Intensive physical therapy was programmed in a rehabilitation unit 1 month later. Pregnancy developed normally and she continued with thiamine and antiemetic therapy. CONCLUSIONS: Wernicke's encephalopathy is an infrequent pathology, but its consequences may be really serious. This is the reason why it is paramount to take into account this entity in pregnant women liable to develop it and to carry out adequate prophylaxis to prevent its appearance and development of posterior sequels.

Psicosis de Korsakoff, a propósito de un caso interesante / Korsakoff's psychosis, about an interesting case

La psicosis de Korsakoff (PK) es una de las causas más frecuentes de amnesia. Se caracteriza por confusión mental, deterioro de la memoria reciente y confabulación. Se presenta el caso de un paciente masculino de 53 años de edad, fumador de un paquete al día, durante más de 35 años, bebedor de riesgo, con antecedentes de hipertensión arterial e hipercolesterolemia. Se diagnosticó como psicosis de Korsakoff debido al déficit de tiamina o vitamina B1. La psicosis de Korsakoff es un síndrome amnésico que puede presentarse precedido o no de encefalopatía de Wernicke (EW), por lo que se diagnostican menos casos de los que en realidad existen. Por ello, es un problema frecuentemente infradiagnosticado en los centros de salud lo que resulta interesante el conocimiento de esta patología (AU).

Korsakoff psychosis is one of the most frequent causes of amnesia. It is characterized by mental confusion, impairment of the recent memory and confabulation. It is presented the case of a male patient, aged 53 years, who smoked 1 packet of cigarettes a day during more than 35 years, risk drinker with antecedents of arterial hypertension and hypercholesterolemia. He was diagnosed as Korsakoff psychosis due to the thiamine or B1 vitamin deficit. Korsakoff psychosis is an amnesic syndrome that may be preceded or not by Wernicke encephalopathy, so there are diagnosed fewer cases than those truly existing. That is why it is a problem frequently underdiagnosed in health care institutions, making interesting this disease´s knowledge (AU).

Wernicke's encephalopathy with chorea: Neuroimaging findings / Encefalopatia de Wernick e Coreia: achados de neuroimagem

ABSTRACT We present a case report of motor and cognitive disorders in a 36-year-old woman with a history of twelve years of heavy alcohol abuse. The patient presented depressive symptoms over the course of one year after a loss in the family, evolving with ataxia, bradykinesia and choreiform movements. Progressive cognitive decline, sleep alterations and myalgia were also reported during the course of disease evolution. Physical examination revealed spastic paraparesis with fixed flexion of the hips and knees with important pain upon extension of these joints. Initial investigation suggested the diagnosis of thiamine deficiency by brain magnetic resonance imaging (MRI).

RESUMO Um relato de caso de transtornos motor e cognitivo em uma mulher de 36 anos, com história de doze anos de abuso de álcool. A paciente apresentou sintomas depressivos ao longo de um ano após uma perda na família, evoluindo com ataxia, bradicinesia e movimentos coreiformes. O declínio cognitivo progressivo, alterações do sono e mialgia também foram relatados durante o curso da evolução da doença. O exame físico demonstrou paraparesia espástica com flexão fixa dos quadris e joelhos com dor importante na extensão dessas articulações. A investigação inicial sugeriu o diagnóstico de deficiência de tiamina por ressonância magnética cerebral (MRI).

Presentación tardía de una encefalopatía de Wernicke tras gastrectomía por adenocarcinoma gástrico: a propósito de un caso / Late presentation of wernicke's encephalopathy after gastrectomy in a patient with gastric adenocarcinoma: case report

La encefalopatía de Wernicke es una emergencia neurológica caracterizada por la tríada clínica clásica de oftalmoplejia, ataxia y alteración del estado mental, que conlleva alta morbimortalidad. Se debe a un déficit de la vitamina B1 (tiamina), que en su forma activa desempeña un papel esencial en el metabolismo de neuronas de áreas específicas del cerebro. Aunque el alcoholismo es la causa más frecuente de este déficit, se han descrito numerosos agentes que pueden alterar la biodisponibilidad o el metabolismo de la tiamina (1), entre las que cabe destacar la cirugía del tracto gastrointestinal, sobre todo tras cirugía bariátrica. Por lo general el cuadro se produce entre las semanas cuatro y doce tras la resección, pero excepcionalmente se han descrito casos que ocurren de forma tardía (años). Presentamos el caso de un paciente intervenido de gastrectomía por un adenocarcinoma antropilórico que desarrolló una encefalopatía de Wernicke a los ocho años de la resección quirúrgica.

Wernicke encephalopathy is a neurological emergency characterized by classic clinical triad of ophthalmoplegia, ataxia and disturbance of mental status, which carries high morbidity and mortality. It is caused by a deficiency of vitamin B1 (thiamine), which plays an essential role in the metabolism of neurons in specific brain areas. While alcoholism is the most common cause of this syndrome, numerous etiologies have been described that alter the bioavailability or metabolism of thiamine (1), among which are included gastrointestinal tract surgery, mainly bariatric surgery. Usually the onset occurs between week 4 and 12 after resection, but some cases have been rarely described to occur late (years). We report the case of a patient who underwent gastrectomy for a gastric adenocarcinoma who developed Wernicke encephalopathy after 8 years of surgical resection.

Edgar Allan Poe and neurology / Edgar Allan Poe e a neurologia

Edgar Allan Poe was one of the most celebrated writers of all time. He published several masterpieces, some of which include references to neurological diseases. Poe suffered from recurrent depression, suggesting a bipolar disorder, as well as alcohol and drug abuse, which in fact led to his death from complications related to alcoholism. Various hypotheses were put forward, including Wernicke's encephalopathy.

Edgar Allan Poe foi um dos mais celebrados escritores do mundo. Ele publicou várias obras primas, algumas delas com referências a diversas doenças neurológicas. O autor apresentou quadro depressivo recorrente, sugestivo de distúrbio bipolar, com abuso de álcool e de drogas, e morreu devido a complicações do alcoolismo, com diferentes hipóteses, incluindo a encefalopatia de Wernicke.

Encefalopatía de Wernicke y polineuropatía asociada a déficit de complejo B después de una cirugía bariátrica / Wernicke´s encephalopathy and polyneuropathy associated with vitamin B complex deficiency after a bariatric surgery

La cirugía bariátrica es un tratamiento que garantiza una pérdida de peso sustancial y duradera, y beneficios tangibles respecto a condiciones médicas asociadas a la obesidad. El aumento del número de cirugías bariátricas ha llevado también a un aumento de las complicaciones relacionadas con ella, incluyendo la encefalopatía de Wernicke y la polineuropatía por deficiencia de vitaminas del complejo B. En este artículo se reporta un caso de encefalopatía de Wernicke siete semanas después de la cirugía, enfatizando en la importancia de reconocer el espectro de la sintomatología para hacer un diagnóstico temprano, que permita intervenir en la fase reversible de esta enfermedad potencialmente letal.

Bariatric surgery is a treatment that guarantees a substantial and lasting weight loss in addition to the tangible benefits relating to obesity-associated medical conditions. The increasing number of bariatric surgeries has revealed an increasing number of complications related to this procedure, including Wernicke´s encephalopathy and vitamin B deficiency polyneuropathies. Herein, a 7-week post-surgery case of Wernicke´s encephalopathy is presented that emphasizes the importance of an early recognition of these symptoms so as to initiate intervention during the reversible phase of these potentially lethal pathologies.

Guía de práctica clínica para la detección temprana, diagnóstico y tratamiento de la fase aguda de intoxicación de pacientes con abuso o dependencia del alcohol Parte I: Tamización, detección temprana y factores de riesgo en pacientes con abuso o dependencia del alcohol / Clinical practice guide for early detection, diagnosis and treatment of the acute intoxication phase in patients with alcohol abuse or dependencepart i: screening, early detection and risk factors in patients with alcohol abuse or dependence

Introducción: El alcohol es la segunda sustancia psicotrópica más usada en el mundo y el tercer factor de riesgo para muerte prematura y discapacidad. Su uso nocivo es un problema de salud pública mundial, dado su impacto personal, laboral, familiar, económico y social. Hasta el 70 % de las personas en riesgo de tener problemas con el alcohol no se detectan en la práctica médica, lo que hace pensar que se requieren medidas de tamizaje específicas que permitan la detección temprana y lleven a un tratamiento oportuno.

Introduction: Worldwide, alcohol is the second most-used psychotropic substance and the third risk factor for early death and disability. Its noxious use is a world public health problem given its personal, labor, family, economic and social impact. 70 % of people under risk of having alcohol problems go undetected in medical practice, a fact that underlines the need for specific screening measures allowing early detection leading to timely treatment. This article presents evidence gathered by alcohol abuse and dependence screening as well as by risk factor identification and screening. It also presents evidence concerning withdrawal symptoms, delirium tremens and Wernicke’s encephalopathy in order to promote early detection and timely treatment. Methodology: Systematic revision of the evidence available together with an evaluation of pertinent guidelines found in literature so as to decide whether to adopt or adapt the existing recommendation for each question or to develop de novo recommendations. For de novo recommendations as well as those adapted, it was carried out an evidence synthesis, together with evidence tables and formulation of recommendations based on the evidence. Results: Evidence was found and recommendations were made for the pertinent screening and search of risk factors, in order to perform a diagnosis and carry out a timely management of alcohol abuse, dependence and ensuing complications: withdrawal syndrome, delirium tremens and Wernicke’s encephalopathy...

Encefalopatia de Wernicke em criança com doença de Crohn / Wernicke encephalopathy in a child with Crohn disease

OBJETIVO: Descrever um caso de encefalopatia de Wernicke associada à doença de Crohn na infância. DESCRIÇÃO DO CASO: Menino de cinco anos, com diagnóstico de doença de Crohn por colonoscopia com biópsia há um ano; desde então, fez uso de diversos medicamentos sem resultados terapêuticos. Evoluiu com pancreatite há três meses, quando foi iniciada nutrição parenteral. Apresentou subitamente sonolência, episódios de frases desconexas e alteração da movimentação ocular. O exame neurológico evidenciou nistagmo vertical para cima em todas as posições e nistagmo horizontal no desvio conjugado do olhar. A ressonância magnética do encéfalo mostrou alterações compatíveis com a encefalopatia de Wernicke, sendo instituído o tratamento com tiamina parenteral imediatamente, com reversão completa dos sintomas por volta do 30º dia de tratamento. COMENTÁRIOS: Embora seja uma entidade rara, deve-se suspeitar de encefalopatia de Wernicke frente à presença de fatores de risco, uma vez que o tratamento imediato evita as sequelas neurológicas.

OBJECTIVE: To report a case of Wernicke encephalopathy associated with Crohn disease in childhood. CASE DESCRIPTION: A five year-old boy with Crohn disease, diagnosed by colonoscopy and biopsy one year ago; he has been treated with many different medications without results. During the past year, the patient was diagnosed with pancreatites and has received parenteral nutrition since then. After three months, the child suddenly presented drowsiness, meaningless speech and ocular movement disturbance. Neurologic examination disclosed upbeat nystagmus in all positions and horizontal nystagmus during conjugate deviation of the eyes. Magnetic resonance showed abnormalities consistent with Wernicke encephalopathy. Parenteral thiamine has been administered soon after diagnosis and by the 30th day of treatment, recovery of symptoms was complete. COMMENTS: Despite being a rare entity, neurological symptoms associated to the presence of risk factors such as prolonged parenteral nutrition should suggest Wernicke encephalopathy. Immediate treatment is important to avoid neurological disabilities.
