Parenteral nutrition is being used increasingly in the treatment of the critically ill patient but it causes complications and metabolic derangement. A patient receiving parenteral nutrition in whom protracted vomiting from intestinal obstruction led to the development of acute cardiovascular beriberi (Shoshin) with severe metabolic acidosis--probably lactic--is described. The acidosis was refractory to bicarbonate infusion and inotropic support but the administration of intravenous thiamine 100 mg resulted in a dramatic recovery. Biochemical confirmation of thiamine deficiency was obtained by the measurement of an elevated thiamine pyrophosphate level (24.4%). The patient received thiamine 2.4 mg weekly, a dose that proved insufficient. Thiamine deficiency should be considered when patients receiving parenteral nutrition develop metabolic acidosis with a wide anion gap, even if vitamin supplementation appears adequate.

Although the occurrence of Wernicke's encephalopathy (WE) in patients on dialysis is frequently alluded to, review of the literature reveals only 3 described cases. We describe 5 patients on dialysis who developed WE in the absence of alcoholism or other predisposing factors. The clinical diagnoses included uremic encephalopathy (2 patients), dysequilibrium syndrome (1), dialysis dementia (1), and brainstem hemorrhage (1). At postmortem examination, classic findings of WE were evident. The rarity of WE in patients on dialysis may in part be explained by studies indicating a genetic defect in transketolase activity. Patients on dialysis are also potentially at risk for thiamine deficiency because of anorexia, vomiting, and intravenous alimentation. Other factors altering thiamine requirements, such as glucose load or infections, may also contribute. Preventable and potentially curable, WE should be suspected in all patients on dialysis who have an unexplained neurological picture.

We reported a case of 4-year-old boy with multiple vitamin deficiencies, especially vitamin B1 deficiency. He had megaduodenum associated with membranous stenosis on upper jejunum. He showed recurrent vomiting at his infantile period, and recently intermittent neurological symptoms. When he was admitted to our hospital, he could not walk and showed masked face, absent deep tendon reflexes, horizontal and vertical nystagmus, proximally dominant muscle weakness and multiple vitamin deficiencies. Oral administration of small doses of vitamin B1 (20 mg/day) could make remarkable clinical improvements. At three weeks after the treatment he could walk and run. Before the admission he had febrile convulsions and showed transiently striatal low density on CT image. We concluded that his neurological symptoms were due to vitamin B1 deficiency associated with megaduodenum. When a patient with intestinal anomaly shows neurological symptoms, we should think of vitamin deficiency.

Propionic acidemia is often manifested during the neonatal period with vomiting, failure to thrive, lethargy, and hyperammonemic coma when catabolism is prolonged. Mild lactic acidosis frequently accompanies metabolic decompensation. We present two patients with propionic acidemia whose initial manifestation was complicated by severe lactic acidosis caused by thiamine deficiency, which resulted from an inadequate supply of, and an increased need for, thiamine during metabolic stress. To prevent acute thiamine deficiency, we propose early vitamin supplementation during treatment of any severe metabolic decompensation accompanied by insufficient food intake.

A 24-year-old woman with a large cell anaplastic CD 30-positive T-cell non-Hodgkin's lymphoma (NHL) developed downbeat nystagmus, anisocoria, and oscillopsia. Prior to overt cerebral invasion by NHL, she had a thiamine deficiency with very low thiamine concentrations in the CSF, probably caused by protracted vomiting and increased vitamin B1 consumption by intrathecal tumor cells. We believe that her neurologic symptoms were caused -- at least partly -- by thiamine deficiency, as she reacted well to thiamine supplementation at the beginning of treatment.

Wernicke's encephalopathy, a serious neurological disorder caused by thiamine deficiency, is most commonly found in chronic alcoholics. We present a typical case of Wernicke's encephalopathy in a non-alcoholic man. Our patient presented with altered mental status, slurred speech, fever, vomiting and headache of one-week duration. An infectious etiology of the symptoms was ruled out by spinal fluid cultures. The patient improved dramatically within 24 hours of administration of thiamine.

Beri-Beri is caused by vitamin B1 (thiamine) deficiency. Thiamine is essential for carbohydrate metabolism and the generation of energy. Depending on age and calorie intake, 1-1.5mg/day are required with a 50% increase during pregnancy and lactation. Fever and increased muscular activity will also increase thiamine requirements (storage in muscles is limited, and reserves are quickly depleted). The sources of thiamine are meat, the outer layer of cereal grains and pulses, nuts, and leafy vegetables. The vitamin is lost during milling and processing and during excessive cooking. Beri-beri takes 2 forms: wet beri-beri which has a high output biventricular failure with edema associated with profound peripheral vasodilation and tachycardia (this also occurs in an acute fulminating form known as shoshin beri-beri) and dry beri-beri with symptoms of peripheral neuropathy with taxia, weakness, paraesthesia, and patchy sensory loss with areflexia. In this form, foot and/or wrist drop may occur. Thiamine deficiency can also produce Wernicke-Korsakoff psychosis characterized by vomiting, horizontal nystagmus, ophthalmoplegia, memory loss, and confabulation. Wet beri-beri is a medical emergency treated by intravenous administration of thiamine for several days. 38 patients (27 men and 11 women) were identified with beri-beri in urban Banjul in the Gambia. 14 had wet beri-beri, 11 a mixed presentation, and 13 dry beri-beri. Most of the patients were disabled for many months. Risk factors were pregnancy, alcohol consumption, fever, exercise, diabetes, and dysentery. 4 of the patients died (2 were in the last trimester of pregnancy). The staple diet in urban areas of the Gambia is imported, polished white rice in a groundnut- or oil-based sauce with fish and vegetables such as peppers, onions, and tomatoes. Meat is too expensive for the urban poor, and fruit and vegetable consumption is highly seasonal and income-dependent. There is little chance that this diet will be changed for the 46% of the population who live in urban areas. It is likely that a substantial proportion of the population has subclinical thiamine deficiency and are at risk of beri-beri. Since thiamine added to imported rice will be destroyed by traditional means of cooking, adding the vitamin to wheat flour may be an appropriate public health measure.

Complications of bariatric operations include the development of nutritional deficiencies. If protracted vomiting is added, severe vitamin depletion could arise such as thiamine deficiency, resulting in the development of Wernicke's encephalopathy (WE). This article describes the rapid onset of WE in a 6-week postoperative morbidly obese woman. Because the occurrence of micronutrient deficiencies is infrequent, although reports are increasing, symptoms may be misdiagnosed leading to possible irreversible effects on the central nervous system. The importance of a prompt diagnosis of this serious complication and of adequate therapy is emphasized.

The neurologic form of beriberi has been described in multiple case reports following bariatric surgery for morbid obesity. Thiamine deficiency occurs due to marked emesis and/or altered absorption secondary to the reconfiguration of the gastrointestinal tract to achieve the malabsorption needed to achieve weight loss. This case report illustrates the typical presentation of a patient after gastric bypass, and highlights the symptoms that bariatric surgeons must detect and reviews the treatment.

A 6-year-old dog, a 4-year-old dog and three 7-week-old puppies were diagnosed with thiamine deficiency caused by feeding sulphite treated meat. The 6-year-old dog presented with a history of inappetence, weight loss and vomiting that rapidly progressed to signs of multifocal intracranial disease including mental dullness, paresis, seizures, spontaneous nystagmus and strabismus. Thiamine pyrophosphate effect was elevated at 58% and magnetic resonance imaging revealed bilaterally symmetrical hyperintensity of the caudate nucleus and rostral colliculi. The dog recovered with thiamine supplementation. The 4-year-old dog and three 7-week-old puppies also presented with rapidly progressive multifocal central nervous system signs including ataxia, paresis, increased muscle tone, seizures, nystagmus and exophthalmos. The 4-year-old dog made a rapid recovery with thiamine supplementation. Euthanasia and necropsy of a puppy revealed malacia of multiple brainstem nuclei and oedema of the cerebral cortex. These findings were consistent with thiamine deficiency.
