[Rapid acquired tolerance to cow's milk by oral route in a case of severe childhood food allergy].

An attempt to desensitize to cow's milk a 5 year-old girl who had been forced to follow a strict egg and milk-free diet with concomitant impossibility of attendance at school, posed major practical problems. In a hospital environment, under cover of treatment with Nalcron and Solemedrol, the re-introduction of milk was started with 10(-10) ml of milk. After a severe episode on the 1st day, the child was able to take 100 ml on the 10th day and thereafter. Today, the child continues with Nalcron treatment, but she no longer has a diet and she leads a normal lifestyle.
