Neonatal diabetes is characterised by hyperglycaemia in the first 6 months of life. Transient neonatal diabetes (TND) is differentiated from permanent neonatal diabetes by its remission in infancy/early childhood, with possible relapse during adolescence in 50% of the cases. Incidence of neonatal diabetes is thought to range from 1:90,000 to 1:160,000. A gene mutation affecting pancreatic beta cells synthesis/secretion of insulin is present in more than 80% of the cases. Overe...

Introduction: Over recent years, hyperinsulinaemic hypoglycaemia is being increasingly recognised in at-risk neonates; it is important to recognise and manage this promptly in view of the risk of hypoglycaemic brain injury.Aims: To recognise signs and symptoms of hypoglycaemia in neonates with hyperinsulinaemic hypoglycaemia.Methods: Neonates from the neonatal intensive care units ...

Introduction: Mammalian sex development is directly dependent on gonadal determination. Whole exome sequencing in patients with differences of sex development (DSD) allows the discovery of new factors involved in human sex development. One of these factors is NWD1 (NACHT and WD repeat domain containing 1) a cytosolic protein that seems to play a role in modulating androgen receptor signaling. We identified variants in the NWD1 gene in six und...

Background: Congenital adrenal hyperplasia (CAH) is a rare form of adrenal insufficiency characterized by impaired cortisol synthesis leading to excessive adrenal androgen production. Little is known regarding the effects of early and chronic androgen exposure in children with CAH, and whether this exposure may increase the risk of developing attention-deficit/hyperactivity disorder (ADHD) during childhood. The only study on the subject, based on a small sampl...

Objectives: To evaluate prognostic factors of the growth hormone (GH) treatment effectiveness in children with Turner syndrome (TS).Methods: Retrospective observational study was conducted for 62 patients with TS (32 girls (52%) with 45,X karyotype, 8 (13%) with mosaic variant 45,X/46,XX, and 22 patients (35%) with structural abnormalities of X chromosome). All patients were treated with GH at a dose of 0.33 ...

Prader Willi Syndrome (PWS) is a rare neuro-genetic disorder inherited as a result of lack of expression in 15q11-13 gene and 70% are paternally inherited. Characteristic features are dysmorphism, behavioural problems, infantile hypotonia, short stature, hypothalamic dysfunction, hyperphagia and morbid obesity. The long-term morbidity and mortality depend on hypothalamic dysfunction and obesity. While multidisciplinary care is essential, growth hormone (GH) is a recognized...

Introduction: The underlying genetic causes of congenital hypothyroidism with gland in-situ (CH GIS) and hyperthyrotropinemia (HT) remain largely a mystery. Thanks to NGS, genetic screening is now finding many novel variants. The challenge is to correctly identify which genes and which variants lead to CH and which cause only a transient HT.Objectives: Our objectives were to evaluate the presence of variants in 14 candid...

Background: Turner syndrome (TS) is caused by a total or partial loss of one X chromosome. Typical features include short stature and primary amenorrhoea. In addition, decreasing trabecular bone mineral density (BMD) and increasing cortical BMD during puberty has been reported at the radius. As chromosomal aberration remains a probable cause of bone changes in TS, we aimed to elucidate whether the karyotype differs among the tissues originating from the three ...

Introduction: Disorder of sex development (DSD) is a challenging condition confronting the patients, their relatives and the clinicians. It is more challenging when this disorder is associated with other extra-genital malformations. This makes their overall management more complex than if they just had DSD. Moreover, some of them have disturbed testicular function.Aim of the work: this work aimed at clinical review of 9 ...

Background: Bardet-Biedl syndrome (BBS) causes early-onset extreme obesity and hyperphagia that is hypothesized to arise from leptin receptor dysfunction. Setmelanotide, a melanocortin-4 receptor (MC4R) peptide agonist, has been shown to induce weight loss in individuals affected by other rare genetic obesity disorders resulting from leptin-melanocortin pathway dysfunction upstream of MC4R.Objective: Report preliminary data on body weight, hunger scores,...
