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.

Many different population groups throughout the world have thiamine deficiency and are at risk of developing severe neurological and cardiac disorders. Alcoholics are most at risk but other important clinical groups should be monitored carefully. The most severe, potentially fatal disease caused by thiamine deficiency is the neurological disorder Wernicke-Korsakoff syndrome. This can be difficult to diagnose and many cases remain undiagnosed. Treatment with thiamine generally results in a dramatic clinical improvement. Thiamine supplementation of stable food products like flour is an effective, simple and safe public health measure that can improve the thiamine status of all population groups.

OBJECTIVES: To estimate the incidence of Wernicke's encephalopathy (WE) and Korsakoff's psychosis (KP) before and after the introduction of thiamin enrichment of bread in Australia. DESIGN AND SUBJECTS: Inpatient records were examined in 17 major public general hospitals in greater Sydney for the 4 years 1993-96 (inclusive) with the International Classification of Diseases (ICD) 9 diagnoses 265.1 (WE), 291.1 and 294.0 (KP). Relevant clinical data were recorded on a specially designed form so that cases could be classified as confirmed or probable WE, confirmed or probable KP, confirmed or probable Wernicke-Korsakoff syndrome (WE + KP) or not WE or KP. The average number of cases of WE + KP was 38 acute (new) cases and 69 total (acute + chronic) cases per annum for all the hospitals combined. RESULTS: This study used the same methods as our earlier retrospective examination of Wernicke-Korsakoff cases in essentially the same hospitals for 1978-93. Records for 1993 were thus pulled twice and, while individual cases (using hospital index number) did not always coincide, the total numbers for 1993 were 69 and 70. For the 5 years after 1991 the number of acute cases of WE and KP in Sydney hospitals was 61% of the number for the 5 years before 1991 (P<0.01). There is, however, no continuing downward trend. CONCLUSIONS: These results are consistent with a 40% reduction of the incidence of acute WE and KP since bread has been enriched with thiamin. The disease complex has, however, not been eliminated. To achieve this, further public health action would be needed, such as addition of thiamin to beer.
