Introduction: CHARGE syndrome is a multi-organ disorder; 67% have mutations in the chromodomain gene CHD 7. Endocrine abnormalities are increasingly recognized and we report our experience in a tertiary endocrine unit.Methods/Study design: Children with CHARGE syndrome attending endocrine clinic were identified and data collected retrospectively from medical notes.Results: 31 patients (13 females) were identified. Mean age was 10.5...

Introduction: We report the complexities in the management of two patients with functioning adrenocortical tumours (ACTs), presenting with features of androgen and cortisol excess, secondary to TP53 variants. Case report: Patient 1 presented with androgen excess (P1, TVs 2mls, penis 10 cm) aged 18 months. He was a known carrier of a maternally inherited TP53 variant. Adrenal androgens were elevated, with a DHEAS level of 86 umol/l (0.0-...

Background: Telemedicine use has increased rapidly during the COVID-19 pandemic, replacing many face-to-face (FTF) consultations. FTF consultations are associated with increased CO2 emissions (CO2em) from travel to clinics. This study evaluates the triple bottom line of children and young people’s (CYP) and parent or guardian experience of a new telemedicine service, estimated CO2em saving from reduced travel and cost saving to families.Methods: Dat...

Background: The choice of hydrocortisone (HC) formulation for children with adrenal insufficiency necessitates considerations for dose accuracy, palatability, and practicality in everyday life to optimise medicine adherence and health outcomes. Recently, several diverse new formulations have become available in the UK, but no information is available on real-life patient preferences for the different formulations.Objectives: Explore patient and parent ex...

Background: Children with hyperinsulinaemic hypoglycaemia (HH) are at a high risk of brain injury, while children with ketotic hypoglycaemia (KH) are believed to be neurologically normal. Hippocampus is known to be susceptible to hypoglycaemia, and is one of the key structures in the memory system. Our objective was to ascertain if children with HH sustain greater hippocampal injury and memory deficits in comparison to children with KH.Methods: Twenty on...

Introduction: Hyperinsulinaemic hypoglycemia (HH) represents the most common cause of hyperinsulinism in neonates, often termed as congenital hyperinsulinism of infancy (CHI). CHI is characterised by inappropriate raised insulin secretion from the pancreatic β-cells in relation to blood glucose concentration. Insulin suppresses NEFA and BOHB production. Neurological damage is a known risk associated with hyperinsulinaemic hypoglycaemia (HH).Aim: To ...

Introduction: Steroid 5-α reductase type 2 deficiency causes 46,XY disorder of sex development (DSD) and is an autosomal recessive disorder resulting from mutations in the SRD5A2 gene. SRD5A2 facilitates the conversion of testosterone to dihydrotestosterone (DHT), crucially required for masculinisation of external genitalia. Thus 46,XY individuals with SRD5A2 mutations present with varying severity of undermasculinisation.We descri...

Introduction: Measurement of the anterior pituitary hormone prolactin is often performed in patients with pituitary pathology. Mild hyperprolactinemia occurs in subjects with hypothalamic disorders and/or pituitary stalk dysfunction, and is also described in patients with isolated optic nerve hypoplasia (ONH), this is proposed to be due to decreased dopaminergic tone.Objective: To assess prolactin levels in patients with septo-optic dysplasia (SOD) (with...

Introduction: CHARGE syndrome is a complex multisystem disorder with characteristic congenital malformations. The spectrum of endocrine abnormalities associated with CHARGE syndrome is not well defined. We report the experience of our tertiary endocrine centre in the management of these patients.Methods/study design: Patients with CHARGE syndrome were identified from the endocrine clinic database and information was gathered retrospectively from medical ...

Background: Intra-uterine growth restriction (IUGR) is a known risk factor for the development of hyperinsulinaemic hypoglycaemia (HH). The phenotype of a large cohort of neonates who develop HH following IUGR has not been studied previously.Aim: To characterise the clinical aspects of a cohort of neonates with IUGR who developed HH.Methodology: Thirty-nine patients with IUGR (defined as birth weight <10th centile) who presente...
