[Hemicrania and food allergy in children].

Ninety-two children affected by migraine were studied, of which 49 had positive skin tests to one or more foods. Forty of those who tested positive (87%) improved after following an elimination diet for 4-6 weeks and were positive for at least one challenge test for the same types of foods which resulted in positive skin tests. Thirty-one children were cured following the elimination diet and 9 improved. At two years, despite the reintroduction of the suspected food or foods 6 to 12 months after the start of the elimination diet, these results remained unchanged.
