Characteristic features include deformity of the skull, maxilla causing craniofacial, dental abnormalities with skeletal changes and short stature. Growth hormone therapy has been attempted in a small group of patients with Pycnodysostosis to promote final adult height, however has not been show...

Background: The mechanisms responsible for inappropriate insulin release from β-cells in congenital hyperinsulinism in infancy (CHI) have largely focused upon defects in KATP channels. Little is known about insulin biogenesis, the profiles of insulin in insulin-containing secretory granules or whether the impact of KATP channel defects is the same in diffuse- and focal disease.Objective and hypotheses: To define the ultrastruct...
