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.

Wernicke's encephalopathy misdiagnosed as schizophrenia： a case report / 四川精神卫生

This article presents a case report of Wernicke's encephalopathy misdiagnosed as schizophrenia. The patient was hospitalized and diagnosed with schizophrenia at a local psychiatric hospital over a month ago. Twelve days ago， the patient gradually developed symptoms such as salivation， difficulty in eating， trembling hands， unsteady walking， glossoptosis and so on. The above symptoms were interpreted as drug-induced adverse reactions and managed accordingly， whereas the patient showed a poor response to treatment， and began to experience intermittent consciousness disorder. After referral to our hospital， findings were diagnostic for Wernicke's encephalopathy and peripheral polyneuropathy. Due to the progression of the disease， the family members abandoned further treatment and requested discharge from the hospital， and the patient died outside the hospital. This case report aims to improve the prognosis of Wernicke's encephalopathy in patients with mental disorder by raising the awareness of the disease and enhancing the early prevention.

Vestibular dysfunction in Wernicke encephalopathy / 中华神经科杂志

Objective:To analyze the abnormal vestibular function of Wernicke encephalopathy (WE) and to explore its diagnostic value.Methods:WE patients who visited the Vertigo Center of the Second Affiliated Hospital of Zhengzhou University from January 2018 to January 2021 were retrospectively collected. All patients were evaluated by clinical neurology. Before treatment, all patients completed video head impulse test (vHIT) and video nystagmusgraphy (VNG) in addition to cranial magnetic resonance and serum thiamine level examination.Results:All 12 patients had a history of eating defects, including 8 cases of alcoholism. All 12 patients had walking instability, 7 cases had dizziness and 8 cases had oscillopsia. Six cases had ophthalmoplegia. All 12 cases showed positive gaze nystagmus. The pathological saccades of bilateral horizontal semicircular canals were found in 12 patients by vHIT before treatment, but there was only 1 patient showing abnormality in vertical semicircular canals, the difference being statistically significant ( P<0.05). All patients could detect bilateral, horizontal, gaze-evoked nystagmus, including 3 cases with vertical nystagmus, 1 case with abnormal saccade test, 3 cases with abnormal smooth tracking test and 1 case with abnormal optokinetic test. There were abnormalities in the caloric test, including 6 cases of bilateral dysfunction and 2 cases of unilateral dysfunction. Conclusions:WE patients may have abnormal vHIT and bilateral, horizontal, gaze-evoked nystagmus, which is similar to the special abnormal signs of simultaneous damage of both peripheral and central vestibular dysfunction.Vestibular function test is valuable for diagnosis of WE, and it is suitable for patients with a history of nutritional disorders who have dizziness or walking instability and suspected WE.

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.

Gastrointestinal Beriberi as a prodrome of non-alcoholic Wernicke’s encephalopathy: a study of an emerging nutritional deficiency disorder from Kashmir, India

Background: Gastrointestinal manifestations of thiamine deficiency have not been well described in literature. Authors aimed to study the symptoms of gastrointestinal beriberi in a cohort of patients of non-alcoholic Wernicke’s encephalopathy and review the relevant literature.Methods: In a retrospective analysis, case records of 52 patients diagnosed with non-alcoholic Wernicke’s encephalopathy were analyzed for the nature of gastrointestinal symptoms, their duration, severity and associated findings, investigations and response to treatment. The available literature on gastrointestinal symptoms in thiamine deficiency disorders and gastrointestinal beriberi was reviewed.Results: Gastrointestinal symptoms were found in 46 of the 52 patients. The most common gastrointestinal symptom in our patients was recurrent vomiting in 42 patients. Eight patients had water brash. Ten patients had epigastric pain and 10 patients had anorexia. Based on the nature and severity of symptoms, patients were evaluated for their symptoms using endoscopy, ultrasonography, amylase and lactate levels, and routine laboratory studies and the results were normal in the majority of patients.  Gastrointestinal symptoms settled in all the patients after receiving intravenous thiamine. On reviewing the literature multiple studies were found to have reported prominent gastrointestinal symptoms in patients of Wernickes encephalopathy and other thiamine deficiency related disorders. However, the definition of gastrointestinal beriberi is not clearly stated.Conclusions: Gastrointestinal symptoms were prominent prodromal manifestations in our cohort of Wernicke’s encephalopathy and have also been amply reported in literature. Presence of gastrointestinal symptoms in individuals predisposed to thiamine deficiency without alternative explanation should be enough to label a patient as gastrointestinal beriberi. The study highlights the importance of recognizing gastrointestinal beriberi as a distinct syndrome that may precede the development of Wernicke’s encephalopathy.

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.

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

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.

Wernicke’s encephalopathy: a case report

Wernicke’s encephalopathy (WE) is an acute neuropsychiatric condition that occurs due to reversiblebiochemical lesions caused by depletion of intracellular Thiamine (Vitamin B1). WE is characterized bythe triad of ophthalmoplegia, ataxia, and confusion. However only 10 % of patients present with all threefeatures and other symptoms may also be present. It is commonly regarded as a condition occurring due tomalnourishment due to alcohol use but a variety of other diseases can also lead to it. It is present in thegeneral population with a prevalence of around 2%. We present herewith a case of a 72 years old lady thatpresented with WE

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.

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.
