Background: Thyrotoxicosis in neonates is a life-threatening condition that can be associated with lasting neurologic problems. Most cases are seen in neonates born to mothers with Graves’ disease in which thyroid stimulating immunoglobulin (TSI) is transferred to the foetus and results in hyperthyroidism. Hypothyroidism due to topical iodine use has been reported in neonates, but thyrotoxicosis has never been described in this age, while in adults is a known entity. We h...

Background: Cannabis use has been legalised in four states in USA. However, endocrine effects of marijuana use are largely unknown. Published experiments on animals have suggested that acute cannabis exposure may lead to suppressed thyroid function, but human studies are limited. Of interest, some studies have shown that cannabis has immunomodulatory effects.Objective and hypotheses: We carried out a cross sectional analysis of data by National Health an...

Background: Children with metabolic syndrome carry an increased risk for development of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) in adulthood. Patients with rare syndromic obesity, such as Bardet-Biedl syndrome (BBS), experience early-onset, severe obesity, which may convey an increased risk for developing obesity-related comorbidities and metabolic syndrome later in life. In clinical trials, treatment with the melanocortin-4 receptor a...

Background: The melanocortin-4 receptor (MC4R) pathway is a key regulator of energy balance and satiety. Variants in genes upstream of MC4R encoding leptin receptor (LEPR), proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1(PCSK1) and those involved in Bardet-Biedl syndrome (BBS) can impair MC4R pathway signaling. Clinically, these variants are characterized by hyperphagia (Pathologic insatiable hunger) and early-onset, severe obesity. E...

Background: Pre-pubertal gynecomastia is characterized by the presence of palpable breast tissue in boys in the absence of signs of sexual maturation. Gynecomastia is common in normal males in the neonatal period, at early puberty, and with increasing age and pre-pubertal gynecomastia is a rare condition and can be associated with excessive aromatase activity or oestrogen-producing adrenal or testicular tumours.Case Presentation: A 3-year-old presented w...

Introduction: Early initiation of diazoxide (DZX) treatment in neonates with HH can prevent permanent hypoglycaemic brain injury. The DZX standard therapeutic dose (STD) is 5 mg/kg/day, and rarely associated with adverse events. There are limited data for the effectiveness and safety of DZX low-dose (<5mg/kg/day) for the treatment of HH neonates.Aim: To assess efficacy and safety of low-dose DZX in HH newborns.<p ...

Introduction: Ectopic posterior pituitary (EPP) is a radiological diagnosis likely caused by a migration defect that occurs during pituitary development. We aim to describe the clinical characteristics and hormonal deficiencies seen in patients with EPP.Method: Longitudinal observational study performed in a single [HK1] [NM2] centre from 1993-2020. As per MRI findings, cases were divided into three cohorts 1) C1: EPP on...

Introduction: Post-prandial hyperinsulinaemic hypoglycaemia (PPHH) is a recognised complication of various gastric surgeries in children, but rarely reported after oesophageal atresia repair. We report two children diagnosed with PPHH post-oesophageal surgery and the challenges of their management.Case 1: A 2-year-old boy diagnosed with oesophageal atresia at birth, was surgically repaired requiring six oesophageal dilatations the first year of life. At ...

Objectives: Differentiated thyroid cancer (DTC) has shown increasing incidence in children and young people <19 years (CYP), and CYP present with more extensive disease than in adults and are at risk of long-term morbidity. A paucity of randomised controlled trials in the field has led to a lack of consensus on how these children should best be managed. These Children’s Cancer and Leukaemia Group and British Society for Paediatric Endocrinology and Diabetes commission...

Background: Hyperinsulinaemic hypoglycaemia (HH) is the most frequent cause of severe and persistent hypoglycaemia in infancy. Prompt recognition and successful management are critical to ensure prevention of hypoglycaemic brain injury and neurological sequelae. The incidence of HH varies from 1:50,000-1:2,500, and mutations in at least 12 different genes involved in β-cell insulin release have been described. Recently, the spectrum of genetic causes for HH has been exten...
