Background: Iodine deficiency has multiple adverse effects in humans, termed iodine deficiency disorders, due to inadequate thyroid hormone production. Iodine deficiency during pregnancy and infancy may impair growth and neurodevelopment of the off-spring and increase infant mortality.Objectives: To evaluate effects of iodine supplementation in pregnant, lactating women and their infants at the East of Ukraine.Methods: Target group...

Aim: To evaluate the metabolic status in children with Turner syndrome (TS) depending on the Tanner stage (Pre-puberty and puberty).Methods: The total studied group consisted of 85 children with TS from 8 to 17 years, who were regularly followed-up in the University hospital (Minsk) and age matched 72 healthy controls. TS was diagnosed in patients with characteristic phenotypic signs according to the results of karyotypi...

Background: Septo-optic dysplasia (SOD) is characterized by two or more features of the triad: optic nerve (ON) hypoplasia, middle brain defects and pituitaty deficiencies. Pituitary Stalk Interruption Syndrome (PSIS) presents as a lack of a visible pituitary stalk and/ or no eutopic posterior lobe hypersignal in the shallow sella turcica. Both conditions usually result in hypopituitarism. The diagnosis is based on clinical signs and MRI findings; only small n...

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 ...

Objectives: To evaluate the prevalence and characteristics of thyroid diseases in children with Turner syndrome (TS).Methods: This is a retrospective study, analyzing clinical data from medical records of 167 patients with TS from 3 to 18 years, who were regularly followed-up in the University hospital (Minsk). Depending on the karyotype, 4 groups of patients were identified: the first group with karyotype 45,X (n</e...

Thyroid carcinoma in pediatric patients usually manifests as an asymptomatic neck mass, with a reported incidence of cervical lymphadenopathy that ranges from 35-83%.Multifocal involvement of the thyroid gland is a well-recognized feature of papillary carcinoma. The reported frequency is about 20%, with wide variations depending on the extent of the sampling and reporting by the pathologistA 12 year old boy presented with t...

Background: Many organs of human body are attacked by autoimmune processes and countless number of genes are involved in their pathogenesis. Diabetes mellitus type 1 (T1DM) attaching pancreas is a common autoimmune disease in childhood. Among autoimmune thyroid diseases (AITD) we can distinguish less frequent in children population- Graves’ disease (GD). Thyroid stimulating hormone receptor (TSHR) gene encodes membrane protein responsible for thyroid metabolism. Interfero...

Background: RARβ cooperates with Nur77 to in-vitro regulate HSD3B2 transcription. NUR77 expression parallels HSD3B2 expression with a much lower level in androgen-producing adrenocortical tissues (childhood virilizing adrenocortical tumours (VAT), fetal zone (FeZ) and zona reticularis, ZR). RARβ is down-regulated in starved, hyperandrogenic H295R cells. However, the mechanisms regulating this expression pattern and the relevance of RARβ to huma...

Background: To date at least 30 genes are known to be associated with idiopathic hypogonadotropic hypogonadism (IHH). Analysis of all these gene candidates by Sanger sequencing would be expensive, labour-intensive and time-consuming. Recent introduction of next-generation sequencing (NGS) enables simultaneous analysis of multiple gene targets making it an attractive approach in such conditions as IHHObjective and hypotheses: To study the spectrum of mole...

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) results from gain-of-function mutations in the AVPR2 gene coding for vasopressin receptor 2 (V2R). In contrast, nephrogenic diabetes insipidus (NDI) is caused by loss-of-function mutations in AVPR2. Here we describe and functionally characterize a novel mutation located in the seventh transmembrane domain of V2R. This mutation was identified in a boy suffering from water-induced hyponatrem...
