Background: Chromosome analysis is always indicated in disorders of sex development (DSD), but the need for karyotyping in gender dysphoria (GD) is less clear.Aims and objectives: We therefore aimed to review the place of routine chromosome analysis in the management of GD in children and adolescents.Patients and methods: Five hundred and twenty children and adolescents with GD have been referred at the time of reporting to the two...

Introduction: Severe generalised recessive dystrophic epidermolysis bullosa (RDEB) is a rare disorder resulting from loss of function mutations in the type VII collagen gene (COL7A1). Although RDEB is characterised by severe trauma induced skin blistering and erosions, it is a multisystem disorder with low bone mass as one of the many complications.Objectives: We sought to describe the prevalence of low bone mass, vertebral fractures and scolios...

Introduction: Cushing’s syndrome is a rare and life-threatening paediatric disease, the diagnosis of which can be challenging given its heterogeneous clinical presentation and the investigation results which are frequently inconclusive.Aim: To assess the reliability of the tests used for screening and for establishing the aetiology of Cushing’s syndrome.Design: We conducted a retrospective study analyzing cases of Cushing...

Introduction: Most adolescents with GID have no overt functional or phenotypic abnormalities to explain their presentation. Currently all female to male (FtM) persons undergo detailed evaluation of adrenal function. This study aimed to determine whether subtle abnormalities of adrenal were present and what the appropriate investigation schedule should be.Methods: Over the past 4 years, 55 biological females aged mean age 16.54 years (13.46–18.37) we...

Background: Glucagon (GST) is used as an alternative to insulin (ITT) to diagnose GH deficiency (GHD) and adrenal insufficiency (ACTHd). However the peak cortisol response to diagnose adrenal insufficiency varies (550, and 500 nmol/l), has been extrapolated from adults undergoing intraoperative stress and not fully validated.Aim: To determine the peak cortisol ‘cut off’ level which most accurately predicts clinically significant adrenal insuffi...

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 ...

Glial cells missing B (GCMB), which is the mammalian homologue of the Drosophila GCM gene, encodes a 506 amino acid parathyroid-specific transcription factor that contains: a DNA-binding domain (residues 21–174); a predicted nuclear localization signal (residues 176–193); an inhibitory domain (residues 258–347); and two transactivation domains (residues 174–263, and residues 428–506). To date only two different GCMB m...

Aim: We describe the natural history, treatment, and clinical outcomes of Multiple Endocrine Neoplasia type 2B (MEN2B) caused by the M918T RET pathogenic variant.Methods: Retrospective case notes review of all young people <18 years presenting to a quaternary paediatric endocrinology referral centre in the UK between 2005-2023 who have MEN2B caused by the M918T pathogenic variant in the RET proto-oncogene.<p clas...

Background: Adrenal cortical carcinoma (ACC) in children is a rare and aggressive disease. Further characterisation of the presenting features and biochemical markers are needed to support earlier diagnosis. Refractory hypertension related to high cortisol concentrations at presentation, and post-operative decrease in cortisol can be challenging to manage. Focus on endocrine management has not been previously described.Case Series: 34 patients (age 2 wee...

Introduction: Hyperparathyroidism (HPT) in children is rare with limited outcome measures post surgery.Methods: Retrospective case review of 26 (14M) children (<16 years) who underwent parathyroidectomies (PTx) between 1978 and 2011.Results: Twenty-six children (14M, 12F) included six neonates with neonatal severe HPT (NSHPT) and 20 older children with HPT (13 sporadic, 7 familial).All NSHPT neonates were...
