RESUMO
PURPOSE: A Cow's milk allergy (CMA) is one of common problems during first year of life. Though milk caused allergic problems, their parents didn't know it, and gave milk to their children. But the parents don't give milk to their children if they know it. Therefore it may cause problems of growth and development in children. The purpose of this study is to analyze those clinical features of milk allergy confirmed by oral provocation test. METHODS: We carried out the retrospective study on 21 patients who had been performed oral milk provocation test at Yonsei university children's allergic clinic. RESULTS: 9 out of 21cases (43%) showed positive milk oral provocation test. The most common clinical symptom & sign was urticaria, followed by respiratory symptoms and abdominal symptoms. The rate which past history and positive skin test corresponded to oral provocation test was very high (100%). CONCLUSION: The most valuable diagnosis of food allergy is oral provocation test. However, predictive value of allergy skin test and past history was very high in milk allergy.
