A number of effective conservative therapeutic means are available for early management of affected children particularly when he is growing older. Despite the demonstrated efficacy of conservative therapy, compliance represents a major and daily challenge. Monitoring therapeutic compliance is thus an important task for physicians in charge of this disease. A better understanding of non-compliance causes is required to improve the follow-up of patients for whom treatment education must be a priority.
