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.

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.

Polioencephalomalacia (PEM) in calves associated with excess sulfur intake / Polioencefalomalacia em bezerros associada à ingestão de alimento com excesso de enxofre

Polioencephalomalacia (PEM) is the morphological characterization for softening of brain gray matter, and excess sulfur intake is one of its main causes. This study describes an outbreak of this disease in 1-to-3-month-old calves in a farm located in Santa Catarina state, Brazil. The herd consisted of 27 Jersey male calves whose diet was composed of initial feed, ground whole corn, and mineral salt. From this herd, 10 animals became ill, showing signs of apathy, anorexia and blindness, evolving to generalized weakness and death. Necropsy was performed in three of these animals, which showed flattening of the cerebral convolutions in addition to softened, yellowish areas in the cerebral cortex. Histopathological examination revealed deep laminar necrosis associated with perineuronal and perivascular edema, as well as neurons with wrinkled, eosinophilic, or vacuolated cytoplasm. The following sulfur doses were observed: 8,010mg/kg in corn, 6,385mg/kg in initial feed, 1,060mg/kg in mineral salt and 2.3mg/L in water, reaching dose values far above the accepted, totaling a daily intake of approximately 6,533.5mg sulfur/animal/day. As differential diagnosis, lead was dosed in the kidneys and liver of the three calves, with negative results. Also, the calf that sickened last was treated with 20mg/kg thiamin and 0.2mg/kg dexamethasone (IM; QID) for three days and eventually recovered. According to anatomopathological findings, excess sulfur intake and therapeutic diagnosis, sulfur poisoning was suggested as the cause of PEM in these 1-to-3-month-old calves. Occurrence of PEM is rare in calves at such a young age.(AU)

A polioencefalomalacia (PEM) é a caracterização morfológica para o amolecimento da substância cinzenta encefálica, e uma de suas principais etiologias é a ingestão excessiva de enxofre. Este trabalho descreve um surto desta enfermidade em bezerros de um a três meses de idade em uma propriedade de Santa Catarina. O lote era composto por 27 bezerros machos da raça Jersey, com alimentação composta por ração inicial, milho inteiro triturado e sal mineral. Deste lote, 10 animais adoeceram, apresentando sinais de apatia, anorexia e cegueira, com evolução para fraqueza generalizada. Nove bezerros morreram e três foram submetidos a necropsia, que demonstraram achatamento das circunvoluções cerebrais além de áreas de amolecimento e coloração amarelada no córtex cerebral. Realizou-se exame histopatológico que evidenciou necrose laminar profunda associada a edema perineuronal e perivascular, além de neurônios com citoplasma enrugado, eosinofílico ou vacuolizado. A dosagem de enxofre resultou em 8010mg/Kg no milho, 6385mg/Kg na ração, 1060mg/Kg no sal mineral e 2,3mg/L na água, atingindo valores muito acima do tolerado, totalizando a ingestão diária de cerca de 6533,5mg de enxofre/animal/dia. Como diagnóstico diferencial realizou-se dosagem de chumbo de amostras de rim e fígado dos três bezerros com resultado negativo. Ainda, o último bovino a adoecer foi tratado com 20mg/Kg de tiamina e 0,2mg/Kg de dexametasona IM, QID, durante três dias e recuperou-se. De acordo com os achados anatomopatológicos e o excesso de enxofre na dieta, sugere-se que a intoxicação por enxofre seja a causa de PEM nestes bezerros de um a três meses de idade, sendo essa enfermidade rara em bovinos tão jovens.(AU)

Bilateral Hearing Loss in Wernicke Encephalopathy

Wernicke encephalopathy is a syndrome caused by thiamine deficiency whose three typical symptoms are ophthalomoplegia, ataxia, and confusion. There are also rare reports of bilateral hearing loss, which can be caused by damage to the bilateral inferior colliculus or thalamic lesions, or by energy failure of the cochlea. This case suggests that thiamine should be administered based on the possibility of Wernicke encephalopathy occurring in malnourished or alcoholic patients with sudden bilateral hearing loss.

Wernicke's Encephalopathy Onset during Diagnosis and Treatment of Peritoneal Mesothelioma:Report of One Case and Literature Review / 中国医学科学院学报

Wernicke's encephalopathy(WE),characterized by nystagmus and ophthalmoplegia,unsteadiness of stance and gait and mental-status changes,is an acute or subacute metabolic encephalopathy of the central nervous system resulting from Vitamin B1(VitB1)deficiency. A 29-year-old male patient was admitted to our hospital due to abdominal pain and fever. He remained chronically undernourished. He was complicated with WE at the late stage of diagnosis,mainly manifested as the convulsion of limbs,ataxia,and delirium. After treatment with VitB1,these neuropsychiatric symptoms were remarkably resolved. His primary disease was later pathologically confirmed as peritoneal mesothelioma.

Thiamine Deficiency in a Child with Short Bowel Syndrome and Review / 대한소아소화기영양학회지

Thiamine (vitamin B₁) is a water-soluble vitamin that is not endogenously synthesized in humans. It is absorbed by the small intestine, where it is activated. Its active form acts as a coenzyme in many energy pathways. We report a rare case of thiamine deficiency in a 3.5-year old boy with short bowel syndrome secondary to extensive bowel resection due to necrotizing enterocolitis during his neonatal age. The patient was parenteral nutrition-dependent since birth and had suffered from recurrent central catheter-related bloodstream infections. He developed confusion with disorientation and unsteady gait as well as profound strabismus due to bilateral paresis of the abductor muscle. Based on these and a very low thiamine level he was diagnosed and treated for Wernicke encephalopathy due to incomplete thiamine acquisition despite adequate administration. He fully recovered after thiamine administration. After 1999 eight more cases have been reported in the PubMed mostly of iatrogenic origin.

Wernicke's encephalopathy in a patient with non-Hodgkin's lymphoma post-Autologous HSCT

SUMMARY Wernick's Encephalopathy (WE) is an acute neuropsychiatric syndrome caused by thiamine deficiency post hematopoietic stem cell transplant (HSCT). WE is associated with high mortality and morbidity rates, but due to its rare occurrence, it is rarely considered in patients submitted to this procedure. Considering that, the manuscript reports the clinical characteristics and the possible factors that predisposed the occurrence of WE in a patient with non-Hodgkin's lymphoma post-Autologous HSCT. We conclude that WE should be considered in patients submitted to autologous HSCT associated with prolonged use of TPN and malnutrition.

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.

Four Cases of Wernicke's Encephalopathy Following Hematopoietic Stem Cell Transplantation / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To make through introduction of Wernicke's encephalopathy (WE) following hematopoietic stem cell transplantation (HSCT) in terms of clinical characteristics, diagnostic process and treatment.</p><p><b>METHODS</b>The clinical charactaristics, diagnostic and therapeutic process and prognostic follow-up in 4 patients diagnosed of WE following HSCT between January 2016 to January 2017 at Department of Hematology, Chinese Aerospace Center Hospital were retrospectively analyzed.</p><p><b>RESULTS</b>Four patients included 2 ALL and 2 AML, and 3 males and 1 female, their age ranged from 8 to 20 years old. 4 patients accouted for about 3% of all petients who received HSCT at that time. Typical triad syndrome consisting of ocular motility disorders, ataxia, global confusion was seen in only 1 patient. However, confusion and heterophthongia as onset of this complication were seen in all patients. Cerebral computed tomograph scan was universally unremarkable and useless. Cerebral MRI scan disclosed that typical involvement including thalamus, fourth ventricle, third ventricle, middle cerebral aqueduct was seen in 3, while untypical site including mamillary body was in the remaining 1 patient. All received vitamin B supplement therapy by intramuscular injection at a dose of 100 mg each day. Initial response was observed at 2, unknown, 3, 4 days after treatment and all obtained complete remission within 2 weeks without any event of relapse after median follow-up period of 8 (7-12) months.</p><p><b>CONCLUSION</b>Any recipient of HSCT with clinical signs or symptoms of central nervous system should receive vitamin B supplementary therapy immediately to decrease risk of mortality of WE even if the diagnosis of WE is uncertain.</p>

Four Cases of Wernicke's Encephalopathy with Impaired Horizontal Vestibular Ocular Reflexes / 대한평형의학회지

Wernicke's encephalopathy (WE) is a neurological disorder induced by a dietary vitamin B1 (thiamine) deficiency which is characterized by encephalopathy, gait ataxia, and variant ocular motor dysfunction. In addition to these classical signs of WE, a loss of the horizontal vestibulo-ocular reflex (VOR) is being reported as the major underdiagnosed symptoms in WE. In this retrospective single center study, we report four cases of WE initially presented with impaired horizontal VOR in addition to the classical clinical presentations, and imaging and neurotological laboratory findings were described.

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 Encephalopathy Associated with Acute Wet Beriberi

Wernicke encephalopathy is usually accompanied with peripheral neuropathy, known as dry beriberi. In contrast, wet beriberi presenting as cardiovascular symptoms rarely occurs. The acute type of wet beriberi can be fatal, if untreated quickly. It is reported that the cerebellar vermis has a role of the coordination and control of cardiovascular and autonomic reflex activities. We report a 58-year-old man showing acute wet beriberi in Wernicke encephalopathy with cerebellar vermis lesion.

Hypothermia Presenting in Wernicke Encephalopathy: A Case Report

Wernicke encephalopathy (WE) is a neurologic disorder characterized by clinical symptoms, such as nystagmus, ataxia, and mental confusion. Hypothermia in patients with WE is a rare complication, and its pathogenic mechanism and therapy are yet to be ascertained. Herein, we presented a case of a 61-year-old man who was diagnosed with WE 3 months earlier. We investigated the cause of hypothermia (35.0℃) that occurred after an enema (bowel emptying). Brain magnetic resonance imaging revealed mammillary body and hypothalamus atrophy. In the autonomic function test, the sympathetic skin response (SSR) test did not evoke SSR latencies on both hands. In addition, abnormal orthostatic hypotension was observed. Laxative and stool softener medication were administered, and his diet was modified, which led to an improvement in constipation after 2 weeks. Moreover, there was no recurrence of hypothermic episode. This is the first reported case of late-onset hypothermia secondary to WE.

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).
