Background: We present a boy with classical adrenal hyperplasia (CAH) and constantly increased 17-OH-progesterone (17-OH-P) values despite multiple dose adjustments of hydrocortisone up to 18 mg/m2 body surface and addition of fludrocortisone. After puberty, therapy was changed from hydrocortisone to prednisone without improvement of the 17-OH-P values. Non-compliance was suspected as cause of the inadequately controlled CAH. Alternatively, an atypical steroid metab...

Background: Medullary thyroid cancer (MTC) in MEN 2A is caused by mutations in RET. Guidelines (2001/2009/2015) recommend prophylactic total thyroidectomy (TT) based on mutation specific risk levels (ATA 2015: high/moderate).Objective: The aim of this study was to analyse changes of age at TT, frequency of metastatic MTC (MMTC), and frequency of TT according to guidelines since introduction of RET testing in 1995....

Background: Hypoglycemia is the most common and most feared complication of insulin treated diabetes. Though mostly asymptomatic, nocturnal hypoglycemia can be fatal in rare cases: sudden nocturnal death is more frequent in diabetic patients than in others. It is postulated that hypoglycemia related QTc prolongation contributes to cardiac arrhythmia and can lead to dead in bed.Objective: To evaluate influence of nocturna...

Background: McCune–Albright syndrome (MAS) is a complex disorder characterized by the triad of fibrous dysplasia of multiple bones, café-au-lait skin macules and endocrinopathies.Objective and hypotheses: Long-term treatment of a boy with gigantism due to MAS.Method: Case report.Results: We present the clinical course of a now 14 years old boy with MAS and GH excess, clinical signs of precocious pub...

Background: Hypoglycaemia represents a common issue in diabetic children, and the achievement of good metabolic control together with the avoidance of hypoglycemia remains a tightrope walk. As hypoglycaemia is not always recognised, data about hypoglycemia frequency are limited.Aims: We previously reported about nocturnal hypoglycaemia in diabetic children. This study now focusses on the frequency and duration of hypoglycemia at daytime and risk factors ...

Background: Hypoglycaemia is the most common and threatening complication in diabetic children. Nocturnal hypoglycaemia is mostly unrecognised and asymptomatic, but recurrent mild hypoglycaemia at night can lead to hypoglycaemia unawareness and reduced performance at daytime.Aims: To evaluate frequency and duration of nocturnal hypoglycaemia in type 1 diabetic children and to identify risk factors for such events.Patients/methods: ...

Introduction: The envelope protein of Human Endogenous Retrovirus type W (HERV-W-Env) has been shown to be associated with type 1 diabetes (T1D) pathogenesis in adults patients. This protein is expressed in pancreas of T1D patients and it seems to correlate with macrophage infiltrations. In vitro and in vivo studies have demonstrated that HERV-W-Env inhibits insulin secretion and promotes hyperglycemia. Furthermore, HERV could be implicated in other auto-immune disorders. The ...

Objective: This feasibility study aimed to investigate the anabolic effect of insulin on metabolites captured in exhaled breath during acute diabetic ketoacidosis (DKA) for a better pathophysiological understanding.Research Design and Methods: Children and adolescents with type 1 diabetes (T1D) with DKA (n=5) and without DKA (n=7) and children with epilepsy without ketogenic diet (n=18) were re...

Background: Copeptin is a surrogate marker for arginine vasopressin (AVP) release in response to hyperosmolal stimuli such as diabetic ketoacidosis (DKA). We aimed to characterize the temporal course (kinetics) of serum osmolality and copeptin during rehydration and insulin therapy in children with type 1 diabetes (T1D) and DKA, and the relationship between both (dynamics).Methods: An observational multi-center study was...

Introduction: Since 2000 understanding of biology of sex development increased tremendously thanks to genetic research. This lead to new classification for persons with disorders/differences of sex development (DSD) based on genetics, and guidelines from the UK recommend revising medical care for persons with DSD by setting up interdisciplinary DSD teams. In Switzerland, persons with DSD asked for better care, stimulating the Swiss National Ethics Commission in 2012 to recomme...
