Background: Congenital heart defects are found in 50% of girls with Turner syndrome (TS). The evaluation of cardiovascular system is an important element in the diagnostic work-up of TS and is of particular significance of cardiologic monitoring, safety aspects of rGH treatment and any pregnancy planning.Objective and hypotheses: Assess the cardiovascular system in TS girls with magnetic resonance imaging of the heart and aorta (CMR and angioMR).<p c...

Introduction: Pituitary gigantism is caused by a somatotroph pituitary tumor that occurs before epiphyseal closure and is associated with increased morbidity due to the systemic effects of chronic hormonal excess. It is an extremely rare disease, with an estimated incidence of 8 per million person-years. Therapeutic modalities for pituitary gigantism are the same as those for acromegaly and include surgery, medication and radiation. Medical treatment plays an ...

Introduction: Growth arrest-specific 6 (Gas6) is a vitamin K-dependent protein produced by several types of cells including adypocytes and regulates their homeostasis. Previous studies indicate that Gas6 signaling may be involved in the pathogenesis of obesity and its complications, including systemic inflammation and insulin resistance. However, little is known about the clinical significance of the Gas6 system in childhood obesity. The aim of the study was t...

Background: Thyroid nodules are quite common in the adult population (13%)but are relatively rarely diagnosed in childhood (0.2-5%).There is a significantly higher risk of malignancy of paediatric thyroid nodules than that in adult patients. The authors of this publication present the observations of the occurrence, diagnosis, and treatment of patients with thyroid nodules in the Department of Pediatric Endocrinology and Diabetology, Medical University...

Background: Gonadotropin-releasing hormone (GNRH) and its receptor (GNRHR) are central regulators of puberty. Loss-of-function mutations of the GNRH-GNRHR signaling pathway are associated with congenital hypogonadotropic hypogonadism, but no mutations were reported so far in patients with central precocious puberty (CPP). Animal data demonstrate the importance of microRNAs in pubertal timing regulation. Among others, miR200b regulates Gnrh1 gene expression in GnRH neu...

Objective: Early genital surgery has been the routine practice in virilized girls with severe forms of CAH for many years. During the last decade studies have shown genital surgery to have unsatisfactory effects on genital sensation and sexuality, and the current practice with early surgery has been questioned by patients and support groups as well as by clinicians and researchers. As surgery has been postponed in only few girls, published data on the effect of hydrocortisone ...

Background: Congenital hypogonadotropic hypogonadism (HH) is a rare but clinically and genetically heterogeneous disease characterized by an absent or incomplete puberty and infertility. The association of HH with hyposmia or anosmia is defined as Kallmann syndrome. Molecular genetic testing of HH is valuable, as it can prompt the treatment in adolescence.Objective and hypotheses: To identify causative variants in genes associated with HH in a cohort of ...

Background: Resistance to thyroid hormones (RTH) is a rare disease, characterized by reduced sensitivity of target tissues to thyroid hormones. Pathognomonically, thyroid hormones are moderately elevated, whereas TSH levels are inappropriately normal or elevated. Over 100 thyroid hormone receptor beta (THRB) mutations have been reported, which are found in around 85% of RTH cases. Hypercholesterolemia was not previously reported in RTH patients....

Introduction: The start of GH (rhGH) treatment in children with GH deficiency (GHD) causes a significant increase in bone turnover and increases height velocity. The increase in IGF1 concentrations during rhGH treatment is a marker of the efficiency of treatment. A significant increase in bone turnover during rhGH treatment results in an increased demand for vitamin D. It is important to determine proper supplementation doses of vitamin D in patients during catch-up growth.</p...

Background: Achondroplasia and hypochondroplasia are more frequent types of skeletal dysplasia. De novo mutations in the fibroblast growth factor receptor 3 (FGFR3) gene are the principal cause. More than 95% of the cases of achondroplasia result from a mutation G1138A (Gly380Arg). In hypochondroplasia we usually (50–70%) found the change C1620A y C1620G, N540K (Asn540Lys).Objective and hypotheses: We describe an skeletal dysplasia...
