[Clinical guidelines «Precocious puberty»].

The precocious puberty is an urgent problem of pediatric endocrinology characterized by clinical and pathogenetic heterogeneity. The appearance of secondary sex characteristics before the age of 8 years in girls and 9 years in boys requires timely diagnosis and the appointment of pathogenetically justified treatment in order to achieve the target indicators of final growth and prevent social deprivation. The developed clinical guidelines are the main working tool of the practitioner.

[Clinical guidelines «Obesity in children»].

The developed clinical guidelines are the main working tool of the practitioner. They briefly and structurally present the main information about the epidemiology and modern classification of obesity, methods of its diagnosis and treatment based on the principles of evidence-based medicine.

High frequency of mutations in 'dyshormonogenesis genes' in severe congenital hypothyroidism.

Objective: Results of the screening of disease causative mutations in congenital hypothyroidism (CH) vary significantly, depending on the sequence strategy, patients' inclusion criteria and bioinformatics. The objective was to study the molecular basis of severe congenital hypothyroidism, using the next generation sequencing (NGS) and the recent guidelines for assessment of sequence variants.

Design: 243 patients with CH (TSH levels at neonatal screening or retesting greater than 90 mU/l) and 56 control subjects were included in the study.

[Significance of determination of antibodies to thyroid-stimulating hormone after discontinuation of antithyroid therapy for Graves disease in children].

Determination of thyroid-stimulating receptor antibodies (TSRA) a promising criterion for discontinuation of antithyroid drug therapy; however, such studies are extremely limited in childhood. The purpose of this investigation was to establish the prognostic value of TSRA on discontinuing antithyroid drug therapy in children with Craves' disease (CD). At the moment of therapy discontinuation, the level of TSRA was higher than the reference range in 15 of 31 children; there were very high values in 2 cases of hypothyroidism that preserved after discontinuation of antithyroid drug treatment.
