[Vitamin B12 deficiency due to abnormal eating habits].
Vitamin B12 deficiency is an uncommon disorder in a prosperous western country. In two children a nutritional vitamin B12 deficiency was observed. The first was a 2-year-old girl with neurodevelopmental regression and macrocytic anaemia, a result of a combination of a maternal vitamin B12 deficiency and inadequate feeding after birth. The second patient was a 14-year-old adipose girl with severe polyneuropathy and mild macrocytic anaemia as a result of a nutritional vitamin B12 deficiency. In her case the deficiency resulted from a bizarre feeding pattern. She turned out to be the victim of child abuse. It is concluded that even in a prosperous western country like the Netherlands vitamin B12 deficiency in children can develop as a result of an inadequate feeding pattern. It can lead not only to macrocytic anaemia but also to severe neurological abnormalities.
