A 55-years-old man with a history of alcoholism, hypertension and obesity was diagnosed of epidermoid carcinoma of the middle third portion of the esophagus. He was treated with two cycles of cytostatics with cisplatin and 5-fluorouracil. Due to his poor general health an inability to swallow solids and liquids, he received parenteral nutrition for 20 days using a commercial formula lacking in vitamins and minerals. During distal esophagectomy we observed a tendency to hypotension and severe metabolic acidosis that was unexplained by the hemodynamic profile and that persisted throughout the first 24 hours after surgery. Once these complications were corrected, he was weaned from mechanical ventilation and the following neurological signs were observed: temporal and spacial disorientation, aphasia, ophthalmoplegia with divergent strabismus and later conduction aphasia, amnesia and confabulation. Circulation was hyperdynamic, requiring inotropics and vasoconstrictors. Korsakoff syndrome secondary to Wernicke's encephalopathy was diagnosed, and the response to thiamine treatment was favorable. Beriberi can be found in hospitalized patients and the anesthesiologist may be involved in their perioperative care. Symptoms resolve easily with vitamin B1 treatment, which is ideally provided along with other hydrosoluble vitamins. Treatment should be prompt because delay leads to greater morbiomortality.

Wernicke's encephalopathy (WE) is a severe brain disorder, first described in 1881, and is caused by a nutritional deficiency of thiamine (vitamin B1) found mostly in patients suffering from chronic alcoholism. In addition, WE can also complicate bariatric surgery if adequate vitamin supplementation is not insured. Without immediate treatment, the prognosis is poor and the mortality rate is high. Most patients present with atypical neurological symptoms, which hampers rapid diagnosis. We present a 40-year-old woman who underwent gastroplasty combined with gastric banding for severe obesity. She experienced repetitive vomiting and her diet was without vitamin supplementation. After three months she developed convergent strabismus, apathy and urinary incontinence, which was diagnosed as WE and treated as such. Six months later her recovery was incomplete, still showing gait difficulties and nystagmus. We aim to show that adequate vitamin supplementation in patients undergoing gastroplasty is necessary, especially considering the risk of permanent neurological deficits.

Early recognition and diagnosis of Wernicke encephalopathy is pivotal for the prognosis of this medical emergency, especially in patients with liver failure which predisposes individuals to develop hepatic encephalopathy. For these patients, distinguishing between hepatic encephalopathy and Wernicke encephalopathy is a challenge in real-world clinical practice.A male patient with 21-year medical history of liver cirrhosis presented diarrhea and ascites. One month before this visit, he was noted to have poor appetite and progressive fatigue. After admission, although several major symptoms, including diarrhea, ascites, hyponatremia, and hypoproteinemia, were greatly improved through appropriate treatments, his laboratory indicators were not changed much. His appetite was not reversed at discharge. On the 5th day after discharge, the patient suddenly became reluctant to speak and did not remember the recent happenings. Simultaneously, unsteady gait and strabismus occurred. On the basis of clinical manifestations and brain magnetic resonance imaging scan results, the patient was diagnosed as Wernicke encephalopathy and these relative symptoms were resolved after intravenous vitamin B1.To our knowledge, this is the second case report of Wernicke encephalopathy developing in a critically ill cirrhotic patient without hepatocellular carcinoma or operative intervention. Wernicke encephalopathy may be underdiagnosed in these patients and this case raises physicians' awareness of its possible onset.

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.
