Background: Sexual maturation is closely linked to growth, suggesting common pathways between the reproductive development and the growth hormone/insulin-like growth factor-I (GH/IGF-I) axis. IGF-I bioavailability is regulated by Pregnancy associated plasma protein-A (PAPP-A), Pregnancy associated plasma protein-A2 (PAPP-A2) and Stanniocalcin 2 (STC2). A large genome-wide association study (GWAS) identified PAPP-A, PAPP-A2 and STC2 to represent loci strongly a...

Background: Many cross-sectional studies have demonstrated that serum testosterone concentration is an important biochemical predictor of bone mineral density in young males, but to our knowledge, no longitudinal studies have been carried out to support these cross-sectional data.Aims: to examine the associations between serum testosterone concentration at the age of 12 and the following gain in bone mineral density unti...

Objectives: -To determine children diagnosed with central congenital hypothyroidism (CCH) by a screening program using TSH and total T4 between May 2016 and January 2019.-To analyze the characteristics of the disease in these children.Material and Methods: During the time of the study, 14.743 newborns have been screened. Cut-off points are used for TSH ≥10MU/ml and T4 6 and 20 mg/dl as lower ...

Uncontrolled diabetes mellitus is a disease with a wide range of systemic complications. Eye complications may seriously threaten quality of life. Diabetic retinopathy is the most frequent diabetic ocular complication. However, diabetic capilaropathy is a little known condition of diabetic retinopathy. It is an acute optic disc edema and/or macular edema; due to an acute hyperglycaemia.Method: We present a case of a diabetic 14-years-old female with diab...

Background: Disorders of sex development (DSD) due to mutations in the NR5A1 (SF1) gene result in a highly variable phenotype.Objective: To report the clinical phenotype and the molecular/structural characteristics of the gene-protein product arising from three novel mutations of the NR5A1 (SF1) gene found in patients presenting with 46,XY DSD.Method: Phenotype determined from interrogation of clinical case notes. Interpre...

Patients who suffer from congenital hypopituitarism display a wide spectrum of phenotypes including pituitary hormone deficiencies and, in some cases, additional extrapituitary manifestations depending on the causative gene. A group of genes underlying hypopituitarism has been identified, yet several of them remain unknown. Here, we identified compound heterozygous variants in the TBC1D32 gene, c.1165_1166dupGT, p.(Gln390Phefs*32) and c.2151delA, p.(Lys717Asnfs*29) in...

Background: Type 1 Diabetes (T1D) is associated with increased fracture risk.Aim: Understand the association between glycaemic control and bone health in children with T1D.Method: Children (n, 32) with T1D and a median (range) age of 13.7 years (10.4,16.4), were recruited to study bone mineral content (TB & LS) and body composition by DXA. All data were corrected for size. Vitamin D, Bone alkaline phosphatase (BAP) and...

Background: Combine pituitary hormone deficiency (CPHD) may be caused by many factors. One – them is PROP1 gene mutation, that causes maldevelopment of GH, TSH, LH, FSH prolactin but not ACTH, producing cells (CPHD–PROP1).Objective and hypotheses: The details of possible differences between phenotypes of CPHD–PROP1 and CPHD of other reasons (CPHD–nonPROP1) are not clear to date. The aim of the study...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...

Background: Donohue syndrome (DS) is the most severe form of insulin-resistance due to autosomal recessive mutations in the insulin receptor gene. Typical features include pre-/postnatal growth impairment, hyperinsulinaemic hyperglycaemia with fasting hypoglycaemia, nephrocalcinosis, recurrent sepsis, little adipose tissue, soft tissue overgrowth, hirsutism, acanthosis nigricans and facial dysmorphism. However, additional comorbidities may be present, affecting prognosis.<...
