Abstract
The classical form of thiamine deficiency in children is comprised of peripheral neuropathy, encephalopathy and high-output cardiac failure, predominantly right-sided. "Shoshin beriberi" cardiac failure has a different presentation, with vasoconstriction, hypotension and severe metabolic acidosis. A three-month breast-fed infant developed these features (biochemical tests confirmed the diagnosis). His mother, although non-symptomatic, had biochemical evidence of thiamine deficiency.
