Objective: IGF-1 receptor mutations (IGF1RM) are a rare abnormality; however, affected patients exhibit severe postnatal growth retardations without catch-up growth. Although several cases of IGF1RM have been described, a comprehensive retrospective analysis of the potential benefit of rhGH treatment is still missing. The aim of this study was therefore to investigate baseline auxology, response to rhGH therapy and potential metabolic effects in patients with IGF1RM in compari...

Background: Dominant mutations in ABCC8 can cause congenital hyperinsulinism (CHI), which is characterised by unregulated insulin secretion.Objective and hypotheses: To understand the molecular basis of medically unresponsive CHI due to dominant ABCC8 mutations.Method: We investigated ten patients with diazoxide unresponsive CHI who required a near total pancreatectomy. DNA sequencing revealed seven dominant heter...

Background: Management of people with T1DM on intensive insulin therapy (IIT) uses algorithms based on the meal carbohydrate (CHO) content (MCC) to calculate prandial insulin dose. Typically, these calculations do not consider the meal content of fat or protein.Objective: To determine if the postprandial blood glucose (BG) response to varying fat content is dose dependent when standard insulin bolus is given based on MCC.Methods: R...

Background: Nicotinamide nucleotide transhydrogenase (NNT) gene mutations have been recently shown to cause familial glucocorticoid deficiency (FGD), by decreasing reactive oxygen species (ROS) detoxification in adrenocortical cells. Affected infants present within the first few months with isolated glucocorticoid deficiency.Objective and Hypotheses: To study the genetic etiology of four cases presenting uniquely with neonatal addisonian crisis (both min...

Background: Endocrine disruptors (ED) can alter endocrine function. ED have become a part of everyday life and are found among phytoestrogens, active ingredients in pharmaceuticals, and additives or contaminants in food, personal care products, cosmetics, plastics and textiles.Objective: To describe cases of children with signs of early puberty who are exposed to ED.Method: Observational study of patients affected of premature pube...
