Review Case ReportsNutritional vitamin B12 deficiency in infancy: three case reports and a review of the literature.
Three cases of vitamin B12 deficiency that occurred during infancy are presented. These cases appeared to be the result of pre-existing maternal deficiency. ⋯ In all three cases the hematologic and neurologic abnormalities were corrected with vitamin B12 therapy. The literature is reviewed and discussed with respect to the mechanism of the infants' vitamin B12 deficiency and neurodevelopmental manifestations.
