Relationships between neuroradiological and clinical features in apparently idiopathic hypopituitarism.

In this study, perinatal history, postnatal auxological and clinical evolution and endocrine features were retrospectively evaluated in 49 children, adolescents and young adults with apparently idiopathic hypopituitarism. They were divided into two groups according to magnetic resonance images: 32 patients with isolated pituitary hypoplasia (group A) and 17 with pituitary stalk interruption syndrome (group B). The aim of the study was to assess whether these neuroradiological pictures are associated with specific endocrine and clinical patterns.

Growth hormone deficient children treated from before two years old fail to catch-up completely within five years of therapy.

We retrospectively investigated growth response to therapy of 12 patients with idiopathic growth hormone deficiency (GHD), who received GH (0.6-0.7 IU/kg/week) in daily subcutaneous injections from before 2 years of age and for a period of 60 months, in order to ascertain whether very early treatment can enable GHD children to catch-up quickly and completely their initial height deficiency.
