The new techniques of molecular genetics are revolutionizing our clinical practice. This causes benefits in the diagnosis and prediction of diseases in patients, but also raises new ethical concerns that must be addressed. One of them is the susceptibility to cancer due to genetic risk. Children can be especially vulnerable in this area, as they do not freely decide the way forward. Regarding thyroid cancer, it is important to know which genetic syndromes are susceptible to ca...

Background: In 2020, the average glycaemic index of Type 1 diabetes (T1D) in Southeast Asia (SEA) countries were reported to be at around 83mmol/mol. In many low-middle-income countries (LMICs) in SEA, insufficient infrastructure, lack of universal health coverage and professional knowledge are factors that affect T1D outcomes that adversely affect mortality and morbidity. Action4diabetes (A4D) currently provides comprehensive partnership programmes with defin...

Background: Rare genetic diseases of obesity are often driven by gene variants in the melanocortin-4 receptor (MC4R) pathway. The MC4R agonist setmelanotide demonstrated significant reductions in body weight in patients ≥6 years old with various rare genetic diseases of obesity, including proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency and Bardet-Biedl syndrome (BBS). While these condit...

Introduction: Duplications of SOX3 at Xq27.1 are known to be associated with a spectrum of midline defects, isolated/multiple pituitary hormone deficiencies and learning difficulties. We report 5 cases of SOX3 duplication with hypopituitarism and differing presentations. 1)Male neonate presented with poor feeding and prolonged jaundice. Investigations revealed central hypothyroidism and inadequate cortisol response to Synacthen. Appropriate hormone replacemen...

Background: Pituitary adenomas secreting GH rarely present in childhood. We report the clinical features, management and outcome of the 5 cases referred to a tertiary Paediatric Endocrine/Neurosurgical service over a 20-year period.Patients: **4 Male:1 Female - all aged 15 years at referral. Tanner puberty stages G3-5; B3. Clinical follow-up data range 2 months – 8 years.Clinical features at presentation: Headache, n=...

Background: Disorders of sex development (DSD) are a group of rare conditions characterized by variable discordance between chromosomal, gonadal and phenotypic sex. An association between smallness-for-gestational age (SGA) and DSD is already recognised, but few studies have investigated this in detail.Aim of study: To evaluate the prevalence of SGA, among patients with DSD and to establish a correlation with the different types and causes of DSD.<p ...

Background: 46,XY DSD is a heterogeneous group of pathologies characterized by a wide spectrum of phenotypes and aetiologies. While advances in molecular genetics have permitted discovery of numerous genes implicated in testicular development, the diagnosis still remains uncertain for most patients with 46,XY DSD.Objective: To identify the aetiologies of 46,XY DSD in Algerian patients.Methods: We conducted a multicentre prospective...

Background: Consultations for infantile hypercalcaemia have increased at Sydney Children’s Hospital since guidelines for vitamin D3 supplementation during pregnancy were introduced in 2006. Recent nationwide shortages of low-calcium formula (LCF) suggest this problem may be widespread.Aim: To determine if infantile hypercalcaemia is occurring more commonly, identify potential aetiologies and clinical significance.Me...

Objective: Recent experimental data suggest that circulating serotonin interacts with bone metabolism, although this is less clear in humans. This study investigated whether serum serotonin interferes with bone metabolism in young women with anorexia nervosa (AN), a clinical model of energy deprivation.Methods: Serum serotonin, markers of bone turnover (osteocalcin (OC), procollagen type 1 N-terminal propeptide (PINP), type 1-C telopeptide breakdown prod...

Background: When a baby presents with atypical genitalia, the most important diagnosis to consider is 21-hydroxylase deficiency (21OHD, CAH, 46,XX). However, primary adrenal insufficiency (PAI) can also occur in 46,XY children with differences in sex development (DSD), although this is less common. Known causes of 46,XY DSD-PAI include high blocks in steroidogenesis (STAR, CYP11A1); steroidogenic enzyme defects (HSD3B2, CYP17A1</...
