Neonatal tuberculosis.

Abstract

SUMMARY A 3 year old girl with Down's syndrome became lethargic and withdrawn, and investigations showed a specific malabsorption of vitamin B12 without proteinuria. Megaloblastic anaemia due to specific malabsorption of vitamin B12 is usually associated with proteinuria. Urban et al reviewed the published reports in 1981 and found only six cases without proteinuria,l and Conway et al reported a further case with neuropathy but without proteinuria.2
