Abstract
A 57-year-old male patient with gastric carcinoma underwent radical distal gastrectomy type II + Braun anastomosis, and received total parenteral nutrition for 10 days after surgery, followed by small amounts of semi-liquid nutrition for 3 days and liquid nutrition for 2 days. The patient developed refractory hypotension for more than 1 week in the early course of disease, and on Day 15 after surgery presented with characteristic signs of Wernicke's encephalopathy, including diplopia and mental confusion. The hypotension did not improve despite appropriate fluid replacement soon after admission. Treatment with moderate dose of thiamine for 3 months partly relieved ophthalmoplegia and confusion, but not Korsakoff syndrome. This extraordinary presentation with refractory hypotension and the unusual course of the disease encouraged us to present this case.

Abstract
Wernicke's encephalopathy is a syndrome characterized by ataxia, ophthalmoplegia, and confusion with thiamine deficiency. We reported on two Japanese brothers with a newly discovered recessively inherited syndrome similar to Wernicke's encephalopathy that developed in the second decade of life; this syndrome was manifested clinically as thiamine-responsive diplopia, ataxia and confusion without serum thiamine deficiency. The patients had complex partial seizure. The administration of high-dose thiamine improved these symptoms. MRI of the brain showed high-intensity signals in the bilateral medial thalamus and periaqueductal region on fluid-attenuated inversion recovery images; these signals were characteristic of findings in Wernicke's encephalopathy. There was no history of chronic alcoholism. The clinical and images features resembling Wernicke's encephalopathy in these patients suggested that the syndrome was caused by a genetic disorder of thiamine metabolism. Genomic analysis of SLC10A3 encoding human thiamine transporter 2 revealed that the patients were compound heterozygotes for the K44E and E320Q mutations. Gene-expression analyses of mammalian culture cells showed that intracellular thiamine uptake activities were decreased significantly. High expression of SLC19A3 RNA in the thalamus may explain the selective thalamic lesions on MRI. The identification of this syndrome proves insight into the thiamine metabolism associated with Wernicke's encephalopathy in humans.

Abstract
Selective cerebral vulnerability is a major consequence of Wernicke's encephalopathy (WE), in which focal areas of the brain exhibit symmetrical profound neuronal loss and accompanying gliosis, occurring most frequently in diencephalic regions such as the thalamus and the mammillary bodies. Many processes have been proposed to explain the selective cerebral vulnerability and the focal neuronal cell death in Wernicke's encephalopathy. There are several mechanisms which are common to the pathophysiology of encephalopathies caused by thiamine deficiency (TD). Recently, emphasis is being placed on deficit in mitochondrial oxidative metabolism, oxidative/nitrosative stress, and the release of proinflammatory cytokines such as IL-1β, IL-6, and tumor necrosis factor-α (TNF-α). Cyclooxygenase-2 (COX-2) plays major roles in regulating brain damage and inflammation. Here we present two fatal cases of non-alcohol associated WE. The immunohistochemical study revealed increased proinflammatory cytokine immunoreactivity in the neurons of the mammillary bodies and medial thalamus, and in the periaqueductal regions, compared with basal constitutive levels of expression in the frontal cortex. Positive (WE cases) and negative (immediate trauma deaths) case-controls were used to confirm the results. TD induced IL-1β proteins weakly, while moderate increase was observed for TNF-α and IL-6. Immunofluorescence analysis by confocal microscopy confirmed the staining results for immunoreactivity in WE brains. Further, the induction of proinflammatory cytokine protein expression levels was quantified by Western blot analysis.

Abstract
Morbid obesity is a curable systemic disease that can cause several complications, including hypertension, diabetes mellitus, and osteoarthritis. However, it is not easy to control solely by conservative management. Bariatric surgeries, such as sleeve gastrectomy and gastric banding, are recently developed treatments that are applied to patients with morbid obesity in Korea. However, gastric surgery can cause surgical or metabolic complications, such as thiamine deficiency, which can lead to Wernicke's encephalopathy. This metabolic complication presents with typical symptoms of confusion, ophthalmoplegia, nystagmus, and ataxia. In this case report, we present a case of Wernicke's encephalopathy, which developed slowly following sleeve gastrectomy in a patient with morbid obesity.

Abstract
We report a 74-year-old man with Wernicke's encephalopathy (WE) whose only prior illness was peptic ulcer disease. Upper gastrointestinal endoscopy demonstrated gastric ulcer scars accompanied by marked deformity, without pathologic evidence of malignancy. WE due to peptic ulcer disease in previous reports was substantially associated with thiamine deficiency due to recurrent vomiting or surgical procedures. In our case, however, there was no history of vomiting or gastrointestinal surgery. Besides, we thoroughly ruled out other known clinical settings related to WE. There is the possibility that peptic ulcer disease itself provoked thiamine deficiency due to malabsorption.

Abstract
INTRODUCTION Wernicke's encephalopathy (WE) is an underdiagnosed condition, usually associated with alcoholism, and has a worse prognosis if there is a delay in diagnosis. A series of 8 non-alcoholic patients with WE is presented and an assessment is made on whether a delay in diagnosis leads to a worse prognosis. PATIENTS AND METHODS The clinical records of patients admitted to 2 university hospitals between 2004 and 2009 with the diagnosis of WE, excluding those with a history of alcoholism, were retrospectively reviewed. RESULTS The study included 4 men and 4 women aged 35-82 of whom 7 had a history of gastrointestinal pathology, and persistent vomiting was the precipitating factor in 7. Encephalopathy was the most frequent onset symptom (4). The classical triad was present in seven patients. Thiamine levels were low in 3/6 and normal in 3/6 cases. MRI was abnormal in seven patients, with high signal intensity in the diencephalon and mammillary bodies (7), periaqueductal grey matter (6), cortex (3) and cerebellum (1). Seven improved with thiamine. Sequelae were mild in 6, and severe in 2 after 6-12 months of follow-up. All patients with a diagnostic delay less than 18 days had mild sequelae. CONCLUSIONS Non-alcoholic WE frequently occurs after gastrointestinal disturbances that could result in lower thiamine absorption. Whereas thiamine levels can be normal in many cases, in almost all cases the MRI shows signal alterations in typical locations. A delay in the diagnosis, and therefore, in treatment leads to a worse prognosis.

Abstract
One of the sequelae of chronic alcohol abuse is malnutrition. Importantly, a deficiency in thiamine (vitamin B(1)) can result in the acute, potentially reversible neurological disorder Wernicke encephalopathy (WE). When WE is recognized, thiamine treatment can elicit a rapid clinical recovery. If WE is left untreated, however, patients can develop Korsakoff syndrome (KS), a severe neurological disorder characterized by anterograde amnesia. Alcohol-related brain damage (ARBD) describes the effects of chronic alcohol consumption on human brain structure and function in the absence of more discrete and well-characterized neurological concomitants of alcoholism such as WE and KS. Through knowledge of both the well-described changes in brain structure and function that are evident in alcohol-related disorders such as WE and KS and the clinical outcomes associated with these changes, researchers have begun to gain a better understanding of ARBD. This Review examines ARBD from the perspective of WE and KS, exploring the clinical presentations, postmortem brain pathology, in vivo MRI findings and potential molecular mechanisms associated with these conditions. An awareness of the consequences of chronic alcohol consumption on human behavior and brain structure can enable clinicians to improve detection and treatment of ARBD.

Abstract
BACKGROUND Although Wernicke encephalopathy (WE) is a preventable and treatable disease it still often remains undiagnosed during life. OBJECTIVES To create practical guidelines for diagnosis, management and prevention of the disease. METHODS We searched MEDLINE, EMBASE, LILACS, Cochrane Library. CONCLUSIONS AND RECOMMENDATIONS 1 The clinical diagnosis of WE should take into account the different presentations of clinical signs between alcoholics and non alcoholics (Recommendation Level C); although prevalence is higher in alcoholics, WE should be suspected in all clinical conditions which could lead to thiamine deficiency (good practice point - GPP). 2 The clinical diagnosis of WE in alcoholics requires two of the following four signs; (i) dietary deficiencies (ii) eye signs, (iii) cerebellar dysfunction, and (iv) either an altered mental state or mild memory impairment (Level B). 3 Total thiamine in blood sample should be measured immediately before its administration (GPP). 4 MRI should be used to support the diagnosis of acute WE both in alcoholics and non alcoholics (Level B). 5 Thiamine is indicated for the treatment of suspected or manifest WE. It should be given, before any carbohydrate, 200 mg thrice daily, preferably intravenously (Level C). 6 The overall safety of thiamine is very good (Level B). 7 After bariatric surgery we recommend follow-up of thiamine status for at least 6 months (Level B) and parenteral thiamine supplementation (GPP). 8 Parenteral thiamine should be given to all at-risk subjects admitted to the Emergency Room (GPP). 9 Patients dying from symptoms suggesting WE should have an autopsy (GPP).

Abstract
Tropical ataxic neuropathy (TAN) and epidemic spastic paraparesis (konzo) are two neurological disorders associated with the consumption of cassava (Manihot esculenta) in several African countries. TAN is characterized by sensory polyneuropathy, sensory ataxia, bilateral optic atrophy and bilateral sensori-neural deafness. It occurs in elderly individuals subsisting on a monotonous cassava diet with minimal protein supplementation. Konzo is a syndrome of symmetrical spastic paraparesis with a predilection for children and young women and invariably associated with consumption of inadequately processed bitter cassava roots with minimal protein supplementation. Despite numerous epidemiological, clinical and biochemical studies aimed at elucidating the etiological mechanisms of these disorders, their etiologies remain unknown, and there is no known treatment. The diseases continue to be prevalent in endemic areas, causing significant disability and increased mortality. A fresh appraisal of the putative etiologic mechanisms proposed for these intriguing and enigmatic syndromes is presented in this paper. Evidences against a causal role for cyanide intoxication are discussed, and evidences implicating thiamine deficiency as a unifying etiological mechanism for these neurological syndromes are presented. It is concluded that urgent research is needed to evaluate thiamine status and implement a therapeutic trial of thiamine in these debilitating neurological disorders.

Abstract
Malabsorptive syndromes and micronutrient deficiencies represent well-known long-term complications of bariatric surgery. Wernicke's encephalopathy (WE), a neurologic manifestation of thiamine deficiency, has been classically associated with alcoholism or severe malnutrition, but rarely reported after bariatric surgery. Herein, we describe the case of a 27-year-old woman that developed WE 10 months after laparoscopic Roux-en-Y gastric bypass for morbid obesity that was initially misdiagnosed with a consequent retard in the appropriate treatment. Although only a few sporadic cases have been reported in the literature, all surgeons and physicians involved in the care of bariatric patients must be aware of this potentially serious complication.

Abstract
Background Beriberi occurs in Vientiane, Lao PDR, among breastfed infants. Clinical disease may be the tip of an iceberg with subclinical thiamin deficiency contributing to other illnesses. Thiamin treatment could improve outcome. Methodology/Principal Findings A cohort of 778 sick infants admitted during one year without clinical evidence of beriberi were studied prospectively and erythrocyte transketolase assays (ETK) performed. Biochemical thiamin deficiency was defined both in terms of the activation coefficient (α>31%) and basal ETK activity <0.59 micromoles/min/gHb. Of the 778 infants, median (range) age was 5 (0–12) months, 79.2% were breastfed, 5.1% had α>31% and 13.4 % basal ETK<0.59 micromoles/min/gHb. Infants ≥2 months old had a higher frequency of biochemical markers of thiamin deficiency. Mortality was 5.5% but, among infants ≥2 months old, mortality was higher in those with basal ETK<0.59 micromoles/min/gHb (3/47, 6.4%) than in those with basal ETK≥0.59 micromoles/min/gHb (1/146, 0.7%) (P = 0.045, relative risk = 9.32 (95%CI 0.99 to 87.5)). Multivariate regression analysis indicated that infant age ≥2 months and fewer maternal years of schooling were independently associated with infant basal ETK<0.59 micromoles/min/gHb. Conclusions/Significance Clinically unapparent thiamin deficiency is common among sick infants (≥2 months old) admitted to hospital in Vientiane. This may contribute to mortality and a low clinical threshold for providing thiamin to sick infants may be needed. Infantile beriberi, or clinical thiamin (vitamin B1) deficiency in infants, is a forgotten disease in Asia, where 100 years ago it was a major public health problem. Infants with this deficiency, commonly aged ∼ 2–3 months, present in cardiac failure but usually rapidly improve if given thiamin injections. It remains relatively common in Vientiane, Lao PDR (Laos), probably because of prolonged intra- and post-partum food avoidance behaviours. Clinical disease may be the tip of an iceberg with subclinical thiamin deficiency contributing to sickness in infants without overt clinical beriberi. We therefore recruited 778 sick infants admitted during one year at Mahosot Hospital, Vientiane, without clinical evidence of beriberi, and performed erythrocyte transketolase (ETK) assays. 13.4 % of infants had basal ETK<0.59 micromoles/min/gHb suggesting biochemical thiamin deficiency. Mortality was 5.5% but, among infants ≥2 months old, mortality was higher in those with basal ETK<0.59 micromoles/min/gHb (3/47, 6.4%) than in those with basal ETK≥0.59 micromoles/min/gHb (1/146, 0.7%) (P = 0.045, relative risk = 9.32 (95%CI 0.99 to 87.5)). We conclude that clinically unapparent thiamin deficiency is common among sick infants (≥2 months old) admitted to hospital in Vientiane. This may contribute to mortality and a low clinical threshold for providing thiamin to sick infants may be needed.

Abstract
The purpose of this study was to determine whether meeting historical criteria for unsuspected Wernicke's encephalopathy (WE), largely under-diagnosed in vivo, explains why some alcoholics have severe neuropsychological deficits, whereas others, with a similar drinking history, exhibit preserved performance. Demographic, clinical, alcohol related, and neuropsychological measures were collected in 56 abstinent alcoholics and 38 non-alcohol-dependent volunteers. Alcoholics were classified using the clinical criteria established by Caine et al (1997) and validated in their neuropathological study of alcoholic cases. Our alcoholics who met a single criterion were considered 'at risk for WE' and those with two or more criteria with 'signs of WE'. Whole blood thiamine was also measured in 22 of the comparison group and 28 alcoholics. Of the alcoholics examined, 27% met no criteria, 57% were at risk for WE, and 16% had signs of WE. Neuropsychological performance of the alcoholic subgroups was graded, with those meeting zero criteria not differing from controls, those meeting one criterion presenting mild-to-moderate deficits on some of the functional domains, and those meeting two or more criteria having the most severe deficits on each of the domains examined. Thiamine levels were selectively related to memory performance in the alcoholics. Preclinical signs of WE can be diagnosed in vivo, enabling the identification of ostensibly 'uncomplicated' alcoholics who are at risk for neuropsychological complications. The graded effects in neuropsychological performance suggest that the presence of signs of WE explains, at least partially, the heterogeneity of alcoholism-related cognitive and motor deficits.

Abstract
Wernicke's encephalopathy is a rare cause of maternal death. It is a difficult diagnosis to make but prevention and treatment is straightforward. Severe thiamine deficiency causes Wernicke-Korsakoff syndrome. Correct diagnosis and treatment with thiamine will decrease the case fatality rate.

Abstract
The purpose of this pictorial essay is to present the computed tomography (CT) and magnetic resonance imaging (MRI) findings of Wernicke's encephalopathy, a rare, severe, acute neurological syndrome due to thiamine (vitamin B1) deficiency, associated with high morbidity and mortality. The classical clinical triad, which includes ocular signs, altered consciousness and ataxia, can be found in only one-third of patients. Although chronic alcoholic patients are the most commonly affected, Wernicke's encephalopathy may complicate malnutrition conditions in nonalcoholic patients, in whom it is greatly underestimated. CT and above all MRI of the brain play a fundamental role in diagnosing the condition and ruling out other diseases. MRI is the most sensitive technique and is required in all patients with a clinical suspicion of Wernicke's encephalopathy. Medial thalami, mamillary bodies, tegmentum, periaqueductal region, and tectal plate are typical sites of abnormal MRI signal. The dorsal medulla, red nuclei, cranial nerve nuclei, cerebellum, corpus callosum, frontal and parietal cerebral cortex are less common sites of involvement although they are more frequently affected in nonalcoholic patients. Paramagnetic contrast material may help to identify lesions not otherwise visible.

Abstract
OBJECTIVE Our aim was to review the emergent neuroimaging findings of alcohol-related CNS nontraumatic disorders. Alcohol (ethanol) promotes inflammatory processes, increases DNA damage, and creates oxidative stress. In addition, the accompanying thiamine deficiency may lead to Wernicke encephalopathy. Associated changes in serum osmolarity may lead to acute demyelination. CONCLUSION Alcohol-related encephalopathies can be life-threatening conditions but can be prevented or treated, if recognized.

Abstract
BACKGROUND Thiamine deficiency has been associated with poorer clinical outcomes. Early recognition of thiamine deficiency is difficult in critically ill patients because clinical signs are nonspecific. OBJECTIVE We determined the prevalence of and identified risk factors associated with low blood thiamine concentrations upon admission of children to a pediatric intensive care unit and evaluated this condition as a predictor of clinical outcomes. DESIGN A prospective cohort study was conducted in 202 children who had whole-blood thiamin concentrations assessed by HPLC upon admission to the intensive care unit. The following independent variables for thiamine deficiency were analyzed: age, sex, nutritional status, clinical severity scores upon admission (ie, the revised Pediatric Index of Mortality and Pediatric Logistic Organ Dysfunction score), systemic inflammatory response measured by C-reactive protein serum concentrations, severe sepsis or septic shock, heart failure, and cardiac surgery. The dependent variables in the outcome analyses were mortality, length of stay, and time on mechanical ventilation. RESULTS Low blood thiamine concentrations upon admission were detected in 57 patients (28.2%) and were shown to be independently associated with C-reactive protein concentrations >20 mg/dL (odds ratio: 2.17; 95% CI: 1.13, 4.17; P = 0.02) but not with malnutrition. No significant association was shown between low blood thiamine concentrations upon admission and outcome variables. CONCLUSIONS The incidence of low blood thiamine concentrations upon admission was high. Of the risk factors examined, only the magnitude of the systemic inflammatory response showed an independent association with this event. The association between thiamine deficiency upon admission and prognosis requires further investigation.

Abstract
A 16-year-old girl was admitted to the emergency department because of acute changes in mental state such as paranoid and nihilistic delusions, confabulations, and distortions of body schema perception. Her history was compatible with anorexia nervosa in that she had lost more than 17 kg in weight over one and a half years. Her body mass index was 14. She was diagnosed with Wernicke Korsakoff's syndrome and was given intravenous thiamine at 250 mg/day. Response was dramatic for nystagmus and gait incoordination but not for other symptoms. After dosage was increased to 750 mg/day all symptoms including psychosis improved. With her increase in food consumption, secondary deterioration was observed and diagnosed as refeeding syndrome. After proper replacements she was completely normal in the 9th month, and her weight was 55 kg. This patient was interesting for the presenting symptoms (psychosis), and improvement by high doses of thiamine replacement, and also for refeeding syndrome during this period.

Abstract
OBJECTIVE To report a case of Wernicke encephalopathy in the early stage after surgery. METHODS A nonalcoholic female patient with hepatitis B-related cirrhosis and hypersplenism underwent splenectomy in a local hospital. No surgical complications occurred and the patient recovered well. However, on the eighth postoperative day she developed psychiatric and neurological disturbance without an obvious cause. She was then admitted to our hospital. Brain magnetic resonance imaging (MRI) with FLAIR T2 showed symmetric high-signal intensities in the periaqueductal area of the midbrain, which were consistent with Wernicke encephalopathy. She was thus given intramuscular thiamine immediately. RESULTS After the administration of thiamine, the patient's confused mental state resolved within 3 d, and her dystaxia gradually improved over the next 5 d. The brain MRI with FLAIR T2 was re-examined one month after the episode, and showed nearly complete resolution of the previously abnormal signal intensities in the periaqueductal area of the midbrain. CONCLUSION Physicians should be aware of the possibility of acute Wernicke encephalopathy, especially in patients with liver dysfunction.

Abstract
OBJETIVO: Transtornos por uso de substâncias são prevalentes em setores de emergência gerais e psiquiátricos, atingindo taxas de 28% das ocorrências em prontos-socorros gerais. Todavia, profissionais dos setores de emergência identificam menos que 50% dos casos de problemas relacionados ao álcool. Este artigo visa fornecer base fundamentada em evidências para o tratamento específico a pacientes que preencham os critérios diagnósticos de transtornos por uso de substâncias e que se apresentam ao pronto-socorro em quadros de intoxicação ou abstinência. MÉTODO: Uma revisão sobre o tema foi realizada na base de dados Medline, usando-se os descritores "intoxicação aguda", "abstinência", "álcool", "cocaína", "cannabis", "opioides", "inalantes" e "manejo", tendo o inglês como idioma. RESULTADOS E CONCLUSÃO: O cuidado de pessoas com transtornos por uso de substâncias deve conter: avaliação completa (médica geral e psiquiátrica), tratamento dos quadros diagnosticados (abstinência, intoxicação e quadros clínicos que caracterizem uma emergência), sensibilização do paciente para realizar tratamento, se for necessário, e elaboração de encaminhamento.

Abstract
Delirium is defined as a disturbance of consciousness with cognitive changes or perceptual disturbances, which has developed over a short period of time, and is caused by a medical condition or a postsurgical state. Although historically dismissed as an inconvenient and transient problem, recent studies have reported that delirium is associated with more complications, increased length of hospital stay, and higher mortality. Although delirium is a prevalent condition after cardiothoracic surgery and in the intensive care unit (ICU), the condition appears to be largely underdiagnosed. Several detection tools have been developed for routine monitoring of delirium by nonpsychiatric personnel in the ICU, such as the Confusion Assessment Method for the Intensive Care Unit and the Intensive Care Delirium Screening Checklist. Management includes treatment of underlying disorders, nonpharmacological measures and symptomatic drug therapy. There is a need for well-designed randomized, double-blind, placebo-controlled trials on drug treatment.

Abstract
A 75-year-old man with diabetic nephropathy treated with hemodialysis visited to a medical office because of slight fever, and received intravenous glucose infusion without any vitamins. Thereafter, he noticed gait disturbance and began to tell inconsistent stories. He was admitted to our hospital due to aggravation of these symptoms. On admission, he was disoriented and not able to sit by himself because of severe truncal ataxia without weakness. He had also gaze direction nystagmus. Based on clinical features, we considered him as having Wernicke's encephalopathy (WE) and treated him with 100 mg thiamine per day. The thiamine supply diminished these symptoms soon. Plasma thiamine level prior to the administration was 7 ng/ml, which confirmed the diagnosis. MRI did not disclose any abnormalities frequently seen in WE. WE is a life-threatening disease, and 'early detection, early cure' is important for recovering without sequelae. The thiamine deficiency is often seen in dialysis patients because of dietary restrictions as well as its loss during dialysis. This case gives us the caution; when hemodialysis patients present acute/subacute gait disturbance and/ or abnormal mental state, we should consider WE. Furthermore, high-risk patients, such as elderly patients under hemodialysis may need some supplement including thiamine even at preclinical stage.

Abstract
AIM To report on two children with encephalopathy caused by dietary thiamine deficiency due to newly developing nutritional problems in contemporary Japan. SUBJECTS A 1-year-old boy who had consumed 1l of isotonic drinks per day for 4 months after an episode of diarrhea, and presented with ocular movement disorder, dystonia, and unconsciousness. The other subject was an 11-month-old boy who suffered from vomiting and somnolence; he and his mother had atopic dermatitis, and he had been on a low-allergen diet that strictly restricted intake of eggs, dairy products, meat, and fish since his early infancy. RESULTS Both patients showed decreased blood thiamine levels and magnetic resonance imaging revealed striatal and thalamic lesions. Thiamine administration yielded prompt improvement of symptoms, but cavitiform lesions in the bilateral putamen persisted in the first patient, accompanied by residual generalized dystonia. Marked elevation of blood/cerebrospinal lactate levels and severe hyponatremia were present in this patient. CONCLUSION Thiamine-deficient encephalopathy in Japanese children due to excessive intake of sports drink or overstrict diet therapy for atopic dermatitis has been increasingly reported during the last decade, but is still not broadly recognized. These children may visit hospitals due to persistent vomiting as a symptom of thiamine deficiency, but glucose infusion without thiamine supplementation can aggravate their condition. Knowledge of these facts in medical and public settings is necessary to correct the erroneous impression that nutritional options given to ill children are necessarily beneficial for health, and promote awareness that they can be harmful when consumed in excess.

Abstract
Nearly two thirds of American adults are either overweight or obese. Accordingly, bariatric surgery experienced explosive growth during the past decade. Current estimates place the worldwide volume of bariatric procedures at greater than 300,000 cases annually. Micronutrient deficiencies are well-described following bariatric surgery, and they may present with devastating and sometimes irreversible neurologic manifestations. Clinical symptoms range from peripheral neuropathy to encephalopathy, and are most commonly caused by thiamine, copper, and B(12) deficiencies.

Abstract
Introduction Wernicke's encephalopathy is an acute, potentially fatal, neuropsychiatric syndrome resulting from thiamine deficiency. The disorder is still greatly under-diagnosed, and failure to promptly identify and adequately treat the condition can lead to death or to the chronic form of the encephalopathy - Korsakoff's syndrome. Wernicke's encephalopathy has traditionally been associated with alcoholism but, in recent years, there has been an increase in the number of clinical settings in which the disorder is observed. Case presentation We report the case of a 45-year-old Caucasian woman who arrived at the emergency room presenting signs of marked malnutrition and mental confusion, ataxic gait and ophthalmoplegia. Main laboratory test findings included low serum magnesium and megaloblastic anemia. Brain magnetic resonance imaging revealed increased T2 signal in the supratentorial paraventricular region, the medial regions of the thalamus and the central and periaqueductal midbrain. The diagnosis of Wernicke's encephalopathy was made at once and immediate reposition of thiamine and magnesium was started. The patient had a long history of recurrent thoughts of being overweight, severe self-imposed diet restrictions and self-induced vomiting. She had also been drinking gin on a daily basis for the last eight years. One day after admittance the acute global confusional state resolved, but she presented severe memory deficits and confabulation. After six months of outpatient follow-up, memory deficits remained unaltered. Conclusion In this case, self-imposed long-lasting nutritional deprivation is thought to be the main cause of thiamine deficiency and subsequent encephalopathy, but adjunct factors, such as magnesium depletion and chronic alcohol misuse, might have played an important role, especially in the development of Korsakoff's syndrome. The co-morbidity between eating disorders and substance abuse disorders has emerged as a significant health issue for women, and the subgroup of patients with anorexia nervosa who also misuse alcohol is probably at a particular risk of developing Wernicke-Korsakoff syndrome. The present case report highlights this relevant issue.

Abstract
PURPOSE With their prolonged survival and malnutrition, cancer patients, and especially gastrointestinal (GI) tract cancer patients, can develop Wernicke's encephalopathy (WE). The aim of this study is to remind physicians of the importance of WE and prompt management in patients with GI tract cancer. MATERIALS AND METHODS This study is a retrospective review of 2 cases of WE in advanced gastric cancer (AGC) patients, and we review the literature for cases of GI tract cancer related to WE. RESULTS A 48-year-old female with AGC presented dizziness and diplopia for 5 days and a 20 kg weight loss. Neurologic exam showed nystagmus and gaze disturbance. Her symptoms improved after daily parenteral injection of thiamine 100 mg for 17 days. A 58-year-old female with AGC presented with sudden disorientation, confusion and 15 kg weight loss. Neurologic exam showed gaze limitation and mild ataxia. Despite daily parenteral injection of thiamine 100 mg for 4 days, she died 5 days after the onset of neurologic symptoms. Combining the cases noted in the literature review with our 2 cases, the 7 gastric cancer cases and 2 colorectal cancer cases related to WE showed similar clinical characteristics; 1) a history of long-period malnutrition and weight loss, 2) relatively typical neurologic signs and symptoms and 3) specific magnetic resonance image findings. Except for 2 patients who had irreversible neurologic symptoms, the other 7 patients were improved with prompt thiamine treatment. CONCLUSION It is important to consider WE in GI tract cancer patients with acute neurologic symptoms and who are in a state of malnutrition. Thiamine should be given as soon as possible when WE is suspected.

Abstract
Resting-state functional MRI (fMRI) is now providing further understanding of neuropsychiatric illnesses. However, its practical applicability in the clinical realms is still questionable. Here we report three consecutive followed-up resting-state fMRI data in a single case with Wernicke encephalopathy before and after high-dose thiamine replacement therapy ranging over 20 months. We measured the mammillothalamic functional connectivity strength between the first ROI (mammillary body) and a voxel which showed the highest co-activation among voxels within the anterior thalamus (the second ROI) to enhance the specificity of the functional connectivity data. We found that the time-series changes in the mammillothalamic functional connectivity generally paralleled to the changes in delayed verbal and nonverbal recall memory scores in the left and right hemisphere, respectively. Among these, the left-side connectivity and delayed verbal recall score seemed to be related to the overall clinical status change. Modified directed transfer function (dDTF) analysis also identified significant information flows with mammillary-to-thalamic direction except at the acute illness state. Our findings, though preliminary in nature, suggest the practical applicability of resting-state fMRI to trace an effect of thiamine replacement therapy on the memory tract function in Wernicke encephalopathy at single-patient level.
