Background: Variety of defective thyroid hormone biosynthesis accounts for 15% of congenital hypothyroidism. Children with IYD gene (formerly DEHALI) mutation, which encodes thyroidal enzyme iodotyrosine deiodinase, cannot recycle iodine in thyroid gland. This results in urinary loss of iodine and hypothyroidism. The condition may be missed by neonatal screening programs.Case description: A male baby was born of non-cons...

Background: Hyperinsulinism represents a group of clinically, genetically and morphologically heterogeneous disorders characterised by β-cell dysfunction in glucose homeostasis leading to excessive insulin secretion with profound and recurrent hypoglycaemia. In most countries it occurs in approximately 1/25,000 to 1/50,000 births. Mutations in at least 14 genes have been reported to cause congenital hyperinsulinism. In nearly half of the cases, cause rema...

Background: Delta-Like Homologue 1 (DLK1) is a gene encoding a transmembrane protein, which may also be secreted into the circulation. DLK1 levels are known to rise in maternal serum during late gestation and our genetic studies in the mouse have shown that this DLK1 arises from the conceptus. However, the cell population that secretes DLK1 into the maternal circulation has not been identified. Since DLK1 has been shown to be differentially expressed in intrauterine growth res...

Background: Current guidelines for girls with gonadal dysgenesis due to Turner Syndrome (TS) recommend initiating estrogen therapy at 11-12 years of age, using 'natural' 17-β estradiol. However, there is scant evidence regarding the optimal modality of induction, particularly concerning whether oral or transdermal routes are more effective or acceptable.Aim: To retrospectively evaluate differences in puber...

Background: Mulibrey nanism (MUL) is a monogenic growth disorder with typical craniofacial features, perimyocardial heart disease, infertility and predisposition to tumors. MUL is caused by mutations in the TRIM37 gene encoding TRIM37 protein possessing E3 ubiquitin-ligase activity.Objective and hypotheses: MUL patients have pre- and postnatal growth failure with an average birth length SDS of -3.1 and birth weight SDS o...

Background: Obesity has in males been associated with reduced testosterone levels during and after puberty. However, the onset and progress of puberty into fertility in obese boys remain inadequately evaluated.Objective and hypotheses: We aimed to study testicular function at the end of pubertal development (15–24 years) in males with severe childhood-onset obesity (height-adjusted relative weight exceeding 160% before the age of 7 years).<p cla...

Background: In mammals, maternal glucocorticoids are transmitted through breast milk, particularly under stressful circumstances. In humans, it is unclear whether milk cortisol levels are dependent on stressful perinatal circumstances, such as preterm birth.Objective and hypotheses: Our aim was to compare cortisol concentrations in breast milk of mothers of very preterm infants (GA <32 weeks) to breast milk cortisol concentrations of mothers of full-...

Background: Insulin pumps are widely used in the treatment of type 1 diabetes mellitus (T1D) in children because of numbers of advantages in compare with multiple daily insulin injections (MDI). However, the long-term efficacy of continuous subcutaneous insulin infusion therapy (CSII) in achieving and maintaining of diabet stability is still not resolved.Purpose: Determine the feffectiveness-related factors of glycemic c...

Background: Growth hormone (GH) deficiency in children, confirmed by stimulation diagnostic tests, in some cases is accompanied by low effectiveness of somatropin replacement therapy, which may be associated with rare genetic syndromes.Aim: To study the growth effects of GH therapy in treating a patient with Floating-Harbor SyndromeMethods: A GH deficiency was diagnosed in a patien...

Background: Introital stenosis in CAH girls could occur due to poor estrogenisation of vaginal tissue. It is unknown whether CAH genital skin is equally capable of responding to estrogens and androgens, depending on form and degree of external virilisation.Objective and hypotheses: To determine the levels of oestrogen α (ERa) and androgen receptors (AR) immunoreactivity in genital tissues of girls with CAH.Method: Surgical was...
