The theme of this year’s meeting is Variety and Variation in Paediatric Endocrinology. Join us in Vienna to explore the diversity we encounter in our discipline and the care that we have to exercise when using the term “normality”. Whilst gaining an update on the latest treatments, clinical best practice and cutting edge research in the field of paediatric endocrinology.

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a regulator of IGF-1 availability, causes postnatal growth failure in humans and mice, at least in part through dysregulation of bone size and density. The present study aimed to determine the effects of Pappa2 gene deletion and the response to recombinant murine IGF-1 (rmIGF-1) on femur microstructure and composition. Hydroxyapatite-related crystallography and ionic substitutions were analyzed by X-ray p...
