[Neurofibromatosis type 1 complications in the pediatric age: follow-up of a hundred cases].

Unlabelled: Neurofibromatosis 1 (NF1) is a frequent genetic disease. Diagnostic criterias were established in 1988. The patients can exhibit various and unpredictable complications.
Objectives: To check the efficiency of a coordinated follow-up in specialized multidisciplinary centers providing a higher quality of management and to have a better knowledge of the complications including their true frequencies.
Population and Methods: We report a serie of 100 NF1 children who were followed-up during 4 years in a specialized center at the Tours University Hospital. Three hospital check-up at 2-5, 6-7, 14-15 years of age were performed as well as an annual physical examination.
Results: In our serie, the mean age was 7.8 years old with a sex ratio of 1. The mean age at diagnosis was 3.8 years old and the main diagnosis criteria were the café-au-lait spots and the family history for 80% of the patients. The optic nerve glioma has a low frequency of 5%. Learning disabilities clearly represent the most frequent complication (46% of the patients).
Conclusion: An early detection of these difficulties is a priority for the appropriate management of these children.
