Introduction: Duplications of the SOX3 gene at Xq27.1 are known to be associated with a spectrum of forebrain midline defects, isolated or multiple pituitary hormone deficiencies, spina bifida and sometimes learning difficulties. We report three cases of SOX3 duplication with hypopituitarism and differing presentations.Case reports: 1) A male infant presented in neonatal period with poor feeding, prolonged jaundice, central hypothyroidism and inadequate ...

Background: Central diabetes insipidus (CDI) presents with various underlying diagnoses in children.Objective: To determine causes of CDI and long-term outcome in children and adolescents from a Tertiary Paediatric Endocrinology unit providing Regional Paediatric Neurosurgery and head trauma services.Methods: The clinic database was searched to identify patients with CDI managed between 1993 and 2019. Relevant clinical information ...

Introduction: Thyrotoxicosis, the commonest cause of which is Graves’ disease, is rare in childhood and adolescence.We report a consecutive series of patients referred to a single tertiary paediatric endocrine centre over 5 years.Methods: Retrospective case note and database review of patients referred 01/2013–02/2018.Results: 27 patients (21F) with Graves’ disease in 21, and Hashitoxicosis in 6. During the same peri...

Background and ObjectiveData on the epidemiology, effects of dopamine agonists and long term outcome of prolactinoma in children and adolescents have been gradually accumulating but are still scarce. We conducted a systematic review and meta-analysis of published literature (1994 – 2019) to study the epidemiology of prolactinoma in patients < 20 years old, and determine the management strategies adopted.Methods: Relevant ...

Introduction: Addison’s disease (AD) is a rare endocrine disorder in children, characterized by insufficient production of cortisol and aldosterone due to adrenal gland dysfunction. While electrolyte imbalances, including hyponatremia, hyperkalaemia, can occur in AD, severe hyponatremia is an unusual and challenging complication in children. We present a case of severe hyponatremia in a teenager diagnosed with AD.Case report...

Background: Mutations in the insulin receptor (INSR) gene are rare and cause a spectrum of severe insulin resistance syndromes including Donohue syndrome, Rabson Mendenhall syndrome, and Type A Insulin Resistance Syndrome (IRS). We describe a young female with a heterozygous INSR mutation, who presented with antibody positive diabetes mellitus (DM) and subsequently developed features of Type A IRS.Case Report: A 12 year old Jamaican gir...

Introduction: Pituitary inflammation (Hypophysitis) is rare in paediatric population and usually results in pituitary enlargement and hypopituitarism. Hypophysitis can be either primary (most commonly lymphocytic, granulomatous or xanthomatous disease) or secondary (consequent to systemic diseases, immunotherapy or alternative sella-based pathologies). We describe the clinical presentation and management of apparent primary lymphocytic hypophysitis in an adolescent girl. Case ...

Objective: To describe the clinical presentation, management and treatment outcomes of prolactinomas diagnosed in childhood and adolescence in a consecutive series.Design and Methods: A retrospective review of medical records of patients with prolactinoma less than 20 years at diagnosis, referred to a tertiary paediatric endocrine service between 1996 and 2018.Results: Twenty-three patients (14 females) were identified; median age ...
