Thiamine deficiency may present four classic clinical forms: peripheral polyneuropathy, anorexia and muscular weakness (dry beriberi); high output heart failure with signs of congestion (wet beriberi); beriberi associated with shock (Shoshin beriberi) and Wernicke's encephalopathy. In this report we describe a picture that is suggestive of severe pulmonary hypertension and cor pulmonale, with j...

The idea that disease may result from the lack of an essential nutrient is now well established. The pioneer work in this field concerned those disorders that seemed to be related in some way to diet. In this category belongs the disease beriberi which is of widespread occurrence in the Far East among people whose staple food is white rice. In his monograph, Vedder (1913) championed the idea th...

INTRODUCTION We describe a case of rapidly progressive and severely debilitating polyneuropathy in a patient with confirmed hypovitaminosis B1, consistent with dry beriberi. Crucially, this is a treatable condition, although sometimes with incomplete recovery, but it is probably under-recognized yet increasingly common given increasing levels of alcohol abuse in the western world. CASE PRESEN...

Bariatric surgery is an effective strategy for achieving substantial weight loss, prolonging survival, and improving the comorbidities associated with obesity. Nutritional deficiency a commonly recognized post-procedural complication. Here, we present case of patient paresthesia, lower extremity weakness, altered mental status one year following Roux-en-Y gastric bypass, who was found to have m...

THIAMIN (vitamin B1) is a water-soluble vitamin involved in glucose metabolism. Its deficiency affects the cardiovascular (wet beriberi) and nervous (dry beriberi) systems, and in industrialized countries, it is commonly linked to chronic alcoholism. Wernicke encephalopathy (WE), a metabolic encephalopathy due to thiamine depletion, is clinically characterized by at least two among four feature...

Cardiovascular beriberi presents as either the fulminant (Shoshin beriberi) or chronic form. Shoshin beriberi is a rare disease that may lead to a fatal outcome if the patient does not receive appropriate treatment. In the present report, we describe the case of a 66-year-old man presenting with leg edema and dyspnea at rest. Clinical presentations were nonalcoholic Shoshin beriberi and lactate...

BACKGROUND The epidemic growth of morbid obesity has led to an increase in the number of bariatric interventions. During the distribution process of bariatric surgical interventions, the risk for severe nutritious complications such as bariatric beriberi can rise. METHODS By means of systematic literature review, epidemiological data, clinical characteristics and diagnostic as well as therape...
