[Graves's disease in children and adolescent: study of seven cases].
BACKGROUND
In spite of its rarity in the paediatric age, Graves' disease constitutes the principal aetiology of hyperthyroidism in child.


OBJECTIVE
Our goal is to analyze the clinical and evolutive particularities of Graves's disease in children.


METHODS
We studied retrospectively seven cases of Graves' disease in children enrolled in the pediatrics department of Sousse during ten years period (1993-2002).


RESULTS
There were six girls and one boy (sex - ratio = 0.16) aged 4.5 to 16 years (mean age: nine years and one month). The diagnosis has been established clinically on the presence of classic symptoms of the illness associated to the biological and radiological findings. As part of research of possible associations with this illness, we observed solely in a case, in addition of Graves's disease, the coexistence of Down syndrome and coeliac disease, rarely described. Among the HLA antigens predisposing the Graves's disease, we only found HLA B8 antigen in a patient. The evolution under antithyroid drug treatment (ATD) has been marked by fast disappearance of functional signs in all patients. However, biological and clinical euthyroidism was more difficult to achieve. The treatment has been stopped in only one patient after 40 months period.


CONCLUSIONS
Graves' disease is usually easy to recognize but difficult to treat. Radical treatments (thyroidectomy or radioactive iodine therapy) are indicated in second intention after having tempted ATD beforehand.
