Introducion: Autoimmune thyroid diseases (AITDs): Hashimoto's thyroiditis (HT) and Graves’ disease (GD) are common chronic autoimmune endocrine disorders in children. The mechanisms leading to the development of these diseases remain unknown, however scientific reports indicate that in addition to environmental factors, genetic background plays an important role. In our previous studies, we showed that some polymorphisms of the genes for IL2RA, FAIM...

Background: The period of 0–6 month of life is a short window for postnatal testicular maturation and the diagnostic of reproductive disorders.Objective: To evaluate the functional condition of the hypothalamo-pitutary-gonadal axis in 1–3 months boys with cryptorchidism.Method: 51 boys ages 1–3 months with cryptorchidism were examined: group 1–30 boys with unilateral inguinal retention testes and group 2–21...

Background: The prevalence of congenital adrenal hyperplasia (CAH) in European countries is reported as 1:10–15 000. It depends on the quality of its diagnostics and efficacy of neonatal screening (NS). In Ukraine the NS was started in 2012.Objective and hypotheses: This is the first study of CAH epidemiology in children 0–18-year-old in Ukraine.Method: In 2013 it was created a database (DB) of Ukrainian children with CAH...

Background: Turner syndrome (TS) is the most well-known and common chromosomal disorder accompanied by delayed growth. According to the Ukrainian national register (UNR) of children with dwarfism the growth retardation is common for all girls with TS.Objective and hypotheses: The aim of the study was to determine the growth parameters of TS girls different age and karyotype, before GH treatment.Method: According to the UNR it was p...

Background: Turner syndrome (TS) is one of the most common genetic disorders associated with abnormalities of chromosome X that occurs in different populations with a frequency of 25–210 per 100 000 female live births.Objective and hypotheses:: The aim of this study was to investigate the prevalence of TS in ukrainian children, as well as frequency variations of karyotype and age of primary diagnosis of TS.Method: We analysed ...

Background: Hypothalamic hamartomas (HH) are rare non-progressive brain tumor malformations that occur early during brain development. Most of the cases are sporadic and nonsyndromic. Variation in size and location of the hamartoma within the hypothalamic region is not always associated with the severity of the clinical presentation. A wide range of symptoms could occur - from nonsymptomatic to severely affected cases that include seizures (mostly gelastic), behavioral difficu...

Background: Polycystic ovary syndrome (PCOS) is associated with metabolic abnormalities and increased insulin resistance (IR), which is closely associated with abdominal obesity and hyperandrogenism in adults. Some studies indicate that hyperandrogenism influences insulin resistance development in PCOS patients. Data on PCOS association with risks of metabolic disorders in adolescence are scars.Objectives: In this study we aimed to investigate androgen p...

Disorders/differences in sex development (DSD) are defined as congenital conditions in which development of chromosomal, gonadal or anatomical sex is atypical. 46,XY DSD include defects in androgen synthesis or action or complete (CGD)/partial (PGD) gonadal dysgenesis. The aim of this study was to characterize the molecular genetic diagnosis of individuals with 46,XY DSD followed at Garrahan Pediatric Hospital.Medical records of 140 patients (P) followed...

Sex chromosome disorders, including sex chromosome mosaicism, result in a large clinical spectrum. There is scarce information about the histological pattern of these gonads.Aim: to characterize the histology and cell markers pattern in gonads of patients with chromosomal mosaicism.Gonadal biopsies from thirteen patients with chromosomal mosaicism, including chromosome Y were studied. Six were rearing as male and s...

Introduction: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the Fas apoptotic inhibitory molecule 2 (FAIM2) gene, the high-affinity alpha subunit (CD25) of the interleukin-2 receptor (IL-2RA) gene, the cytotoxic T cell antigen 4 (CTLA-4) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective: To estimate...
