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...

Background: Paediatric thyrotoxicosis is both rarer and more severe than in adulthood, rendering management difficult, and often unsatisfactory.Objective: To review outcome in a geographically defined area between 1989 and 2013; hence to develop an algorithm for improved clinical care.Method: Retrospective case note review plus questionnaire to family doctor requesting update. Graves’ disease (GD) was defined as positive TSH-R...

Objective: This project aims to evaluate the effect of two isotopically labelled internal standards on the quantification of 17OHP by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) as an orthogonal technique.Methods: Three LC-MS/MS and one GC-MS/MS laboratories, spanning four countries worldwide, who routinely measure serum17OHP, compared two internal ...

Background: Hypoglycaemia due to congenital hyperinsulinism (CHI) usually presents early (E-CHI) in the neonatal period, but late presentation (age >1 month) (L-CHI) also occurs. Adverse neurodevelopment is well recognised in both early and late CHI, but differences between both groups are not known.Objective and hypotheses: We examined a cohort of children with E-CHI and L-CHI to test neurodevelopmental outcomes in mid-childhood.<p class="abstex...

Background/hypothesis: Congenital hyperinsulinism in infancy (CHI) mainly arises from mutations in ATP-sensitive potassium channel genes. However, the expression pattern of defects can be markedly diverse. In diffuse CHI (CHI-D) all islet cells express gene defects, whereas patients with focal CHI (CHI-F) only express defects in a localised region of islet cells due to loss of a maternally-imprinted locus. Here, we examined the properties of a novel population of CHI islet cel...

Background & Aims: Children with acute lymphoblastic leukemia (ALL) frequently receive high doses dexamethasone during treatment, which may induce acute side effects. The aims of the current study were to determine the influence of a five-day dexamethasone course on changes in leptin, fat mass, body mass index (BMI), hunger, sleep and fatigue and to explore the associations between these changes.Methods: Pediatric AL...

Background: Congenital adrenal hyperplasia (CAH) and long-term glucocorticoid treatment may be associated with an increased risk of developing cardiometabolic sequelae such as abnormal glucose homeostasis, hyperlipidaemia, hypertension, cardiovascular (CV) disease, obesity and osteoporosis.Objectives: To study the current practice amongst expert centres for assessing cardiometabolic outcomes in adult patients with 21-hyd...

Background: Virtual environments have proved to be successful for educational purposes in different fields. Multimedia applications might be used to consolidate and internalize informations and behavioral strategies in type 1 diabetic children.Aim: In the last years our Diabetology Division and the Department of Informatics co-created many multimedia applications (edutainments, virtual environments, role serious games, electronic diary smartphone apps, a...

GH deficiency (GHD) associated hypoglycaemia in infancy is an indication for GH treatment, although it is described in GHD1in older children. At that time, GH is prescribed in GHD for short stature. Here, two children are described in whom hypoglycaemia is the main reason to treat with GH. Patient one had hypoglycaemic seizures due to GHD in infancy. GH treatment was stopped with 5.5 y for reassessment. Growth rate diminished and hypoglycaemias occurred. Treatment of GH was re...

Background: A case of hypopituitarism usually related to hypothyroidism and hypoadrenalism. The unexpected effect of somatropin treatment is reported presented with clinical signs.Method and results: A 4-year-old adynamic boy in a wheel chair with normal height (105 cm, −0.7 SDS) but low weight (13 kg) and reduced TSH and thyroid hormones was transferred for further endocrine evaluation. Born after twin pregnancy in 35 weeks (2780 g, 49 cm, and 34 ...
