Unusual presentation of adverse reactions to cow's milk proteins.

Allergy to cow's milk most commonly give symptoms from the gastrointestinal tract, the skin or the respiratory tract. Here two patients are described, with symptoms not so common. One with cerebral symptoms and the other with enuresis. Infantile colic occurs more or less in about 20% of all infants. We have found that in about 1/3 of breastfed infants with infantile colic the symptoms disappeared when the mothers had a cow's milk free diet. We have also managed to analyse the content of the cow's milk protein beta-lactoglobulin in the human milk.
