Background: Gliomas are the most common subgroup of CNS tumours in children. Histologic grading is a means of predicting the biological behavior of these tumours and survival is strongly correlated with tumour gradation. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth.

Background: In a recent report we have identified multinodular goiter (MNG) as a condition with an increased risk for thyroid malignancy in children and adolescents.Objective and hypotheses: To report the prevalence and characterization of a prospectively and uniformly followed cohort of pediatric patients with MNG and to retrospectively analyze differences between benign and malignant MNG before surgery in order to identify malignancy predictors.<p ...
