Background: Maturity Onset Diabetes of the Young (MODY) constitutes a genetically and clinically heterogeneous type of Monogenic Diabetes (MD). It is characterized by early onset, autosomal dominant inheritance and a defect in β cell insulin secretion. To date 14 different MODY subtypes have been reported each one with a distinct genetic aetiology. However four are the most common subtypes, namely MODY 1 (HNF4A), MODY2 (GCK), MODY3 (HNF1A), MODY...

Introduction: The hypothalamic melanocortin-4 receptor (MC4R) pathway plays a vital role in energy balance. Genetic defects in the MC4R pathway may result in severe early onset obesity.Objective: The TEMPO registry (NCT03479437) aims to identify and enroll approximately 1000 participants with rare genetic forms of obesity that are potentially related to key genes, upstream or downstream, of the MC4R. In addition, the TEMPO registry will evaluate the burd...

Background: GnRH analogue and subsequent oestradiol treatments are indicated to alleviate gender dysphoriain adolescent male to female young people (MtF; transgirls). Side effects include impairments in gonadal histology that may cause infertility or biological sterility. Current guidelines encourage professionals to address potential infertility risk and fertility preservation options with transgender youth and their families before starting these treatments.<p class="abs...

Prior to menopause, it is known that women have a lower risk of cardiovascular disease (CVD) and coronary heart disease compared to age-matched men; it is reported that women have around half the CVD risk and almost a 10-year delay in first myocardial infarction event compared to men. Sex differences in serum lipids could contribute to CVD risk through driving atherosclerosis, the buildup of lipids in the sub-endothelial intimal layer of medium-sized to large arteries. We hypo...

Background: Craniopharyngioma is a non-malignant embryonic tumour in the pituitary-hypothalamic area, associated with hypothalamic obesity. Dysfunctional parasympathetic nervous system activity has been proposed as one mechanism underlying alterations in energy metabolism. Arterial spin labelling (ASL) is a non-invasive MRI technique that quantifies brain tissue perfusion as a proxy for functional activity. Here, we measure cerebral perfusion in patients with ...

Background: Craniopharyngioma is a non-malignant, embryological brain tumour in the sellar and parasellar region. Hypothalamic damage is common and accompanied by development of obesity in at least 50% of cases. Mechanisms underlying hypothalamic obesity in craniopharyngioma patients however remain unclear and treatment options are invasive and limited. This feasibility study included a novel application of functional neuroimaging, an established method in obe...

Introduction: Recombinant Growth Hormone (GH) has changed the lives of many patients with Prader-Willi Syndrome (PWS). GH treatment has beneficial effects on body composition, physical performance, cognition, psychomotor development, respiratory function and quality of life of patients with PWS. Due to the narrow therapeutic range, GH treatment is subject to strict limits. Clinicians measure serum immunoreactive Insulin-like Growth Factor 1 ('total IGF-I&#...

Background: The management of MEN1 in CYP<19 years is challenging due to its rarity, and diverse presentations of its component tumours to several adult and paediatric medical and surgical specialists. There is little high quality evidence for treatment recommendations.Aim: To ensure age- and tumour-specific paediatric and adult teams are involved in co-ordinated discussions to improve high quality care and hence survival and reduce long term morbidi...

Background: Transient Generalized Glucocorticoid Hypersensitivity (TGGH) is a rare disorder characterized by increased tissue sensitivity to glucocorticoids and compensatory hypoactivation of the hypothalamic–pituitary–adrenal (HPA) axis. The condition itself and the underlying molecular mechanisms have not been fully elucidated.Objective and hypotheses: To present the clinical manifestations, endocrinologic evaluation and molecular studies in ...

Background: Diabetic ketoacidosis (DKA), a frequent complication of type 1 diabetes (T1D), is characterized by hyperosmolar hypovolemia. The response of water-regulating hormones to DKA treatment in children is not well known. While arginine vasopressin (AVP) is thought to respond to changes in osmolality, aldosterone and atrial natriuretic peptide (ANP) are expected to respond to volume changes (dehydration and overhydration, respectively). The objective of t...
