Milk intolerance in infancy.

Allergy to cows' milk-protein is an occasional cause ofpersistent diarrhoea (Clein, 1954; Collins-Williams, 1954; Kane, 1957; Bachman and Dees, 1957a, b; Davies, 1958), but in the absence of other overt signs of allergy, may easily be overlooked. The management of milk intolerance often involves the use of synthetic feeds, which in themselves may produce a fulminating illness (Wilson and Clayton, 1962); hence the necessity for vitamin and amino acid supplements stressed by these workers and by Mann, Wilson, and Clayton (1965) and Clayton, Arthur, and Francis (1966). This paper describes four cases of milk-protein intolerance. Problems encountered with diagnosis and with the use of synthetic feeds are discussed.
