Background: Hypothalamic-pituitary (HP) deficiencies are frequent in childhood brain tumor survivors (CBTS) after cranial radiation. There is currently no consensus on the most optimal way to screen for HP dysfunction regarding diagnostic tests or time interval. It is not known whether MRI changes in time in the HP-region or in brain volume are predictive of HP dysfunction.Aim: To quantify changes in the HP-region and in brain volume on MRI in CBTS after...

Background: The majority of children diagnosed with idiopathic isolated growth hormone deficiency (IIGHD) show a normal growth hormone (GH) secretion (assessed by GH stimulation tests) when retested at near adult height (NAH). It appears plausible that if normal stimulated GH secretion is observed in mid-puberty, continuing recombinant human GH (rhGH) treatment may only have a minor effect on NAH. The effect on NAH has never been investigated in a prospective ...
