Refractory proctocolitis in the exclusively breast-fed infants.

The arm of this review was to help general pediatricians and primary care physicians in diagnosing and managing cow's milk protein allergy in exclusively breast-fed infants. Allergic proctocolitis is a cause of rectal bleeding in exclusively breast-fed infants aged from 1 to 6 months.It is due to cow's milk protein transferred via breast milk. Diagnosis is based on clinical features and recovery after dietetic therapy. Rectal bleeding generally resolves within 72-96 hours of cow's milk protein maternal avoidance. Most infants tolerate cow's milk by their first birthday.
