A study amongst schoolboys in villages around Hyderabad, India, showed that almost all the boys had riboflavin deficiency, 61% had pyridoxine deficiency, and 9.4% had thiamin deficiency as judged by enzymic tests.<\/jats:p><jats:p>2. The prevalence of angular stomatitis was 41.3% and that of glossitis was 18.2%. Biochemical deficiency of riboflavin and pyridoxine was marginally higher in children with angular stomatitis with or without associated glossitis, than in children without oral lesions.<\/jats:p><jats:p>3. Treatment with B-complex vitamins (containing 4 mg riboflavin and 10 mg pyridoxine) daily for 1 month produced significant reduction in the prevalence of glossitis but had no effect on angular stomatitis. The latter responded to topical application of gentian violet.<\/jats:p><jats:p>4. Small but significant changes in erythrocyte enzymes occurred over the period of 1 month even without vitamin supplements.<\/jats:p><jats:p>5. Results suggest that while glossitis is a relatively early manifestation of riboflavin or pyridoxine deficiency or both, angular stomatitis has a more complex aetiology perhaps associated with infection.<\/jats:p>","DOI":"10.1079\/bjn19790058","type":"journal-article","created":{"date-parts":[[2005,9,17]],"date-time":"2005-09-17T04:07:20Z","timestamp":1126930040000},"page":"431-441","source":"Crossref","is-referenced-by-count":38,"title":["Relationship between biochemical and clinical indices of B-vitamin deficiency.
