[Hemorrhage caused by vitamin K deficiency in the post-natal period]. / L'emorragia da deficit di vitamina K in epoca post-neonatale.

The paper describes 8 cases of delayed haemorrhagic disease caused by vitamin K deficiency, occurring from 16 days to 3 months after birth and observed in 1982-87. All these infants were breast fed and had received no vitamin K prophylaxis. On the basis of these findings, the preventive role of vitamin K in breast fed infants is emphasised.
