Background: Homozygous mutations in STAT5B result in GH insensitivity and immune dysfunction. Heterozygous dominant negative mutations have not been described.Aims and objectives: To characterize genomic STAT5B DNA in two families exhibiting short stature.Methods: Sanger sequencing of STAT5B from genomic DNA. Mutant STAT5B constructs were expressed in HEK293 cells.Results: ...

Background: To delineate testicular responses to gonadotropin replacement in young males with genetically proven CHH.Patients and Methods: In n=72 young males with CHH and at least one variant detected within twenty-four investigated known CHH genes, gonadotropin replacement with hCG and rFSH s.c. was performed over a mean of 2±1 years. Bi-testicular volumes and serum Inhibin B served as baseline parameters, ...

Males with Klinefelter syndrome (KS) have impaired gonadal function due to sex chromosome aneuploidy (47,XXY), ultimately resulting in testicular atrophy and hypergonadotropic azoospermia, thus infertility. At what time serum testosterone (T) concentrations decline in affected individuals, thereby indicating lifelong replacement, is not predictable. An early testosterone treatment provides potential benefits with respect to body composition, neuro-muscular function and final h...

Background: The length of patient survival after cancer treatment is increasing and in some cases does not differ from the average life span in healthy individuals.Objective and hypotheses: The aim of the study is evaluation of thyroid function after oncologic treatment in children.Method: A group of 158 patients aged 16–25 who underwent oncologic treatment in childhood and the control group −66 children and young adults...

Growth failure is common in radiotherapy-treated long-term survivors of pediatric brain tumors. The aim of this study was to assess the changes in growth patterns before and after brain tumor diagnosis, the final height, and the risk factors for compromised growth. The incidence and treatment practices of growth hormone deficiency were analyzed.Methods: A cohort of 73 long-term survivors of childhood brain tumor (median age 27.2 years) w...

Objective: To evaluate the level of 25 (OH) D – vitamin in obese adolescents living in the South of Russia.Materials and method: We examined 20 obese adolescents with varying degrees of severity, aged 15.5±0.3 years, ten girls and boys. The comparison group consisted of ten healthy adolescents matched for age and sex. Obesity was calculated by BMI. Level of 25-(OH) D – vitamin was studied in the laboratory by ELISA (nmol/l). Furthermore, t...

Clinical Case Description: Patient, 14 years 6 months old, complained of irregular menstrual cycle. On clinical examination, sexual development was Tanner 4, Me at 13 years old, the girl had 3 menses, with a last delay up to 8 months. Single terminal hairs along the white line of the abdomen, areola. The patient had epicanthus and narrowed eye slits of different sizes. She was operated on for congenital blepharophimosis in infancy. No one has similar problem...

Context: Off-label and unlicensed use is widespread in medical therapy of children. Since 2007 there is an EU regulation, which includes the need for a pediatric investigation plan (PIP) in the drug approval process. In 2018, hydrocortisone granules in capsules for opening (Alkindi®) became the first medicine to be approved for the treatment of adrenal insufficiency in children from birth.Methods: An anonymised onli...

Amiodarone induced hyperthyroidism is a known side effect of amiodarone treatment. In the pediatric population long-term amiodarone treatment is rarely indicated because of its severe side effects including thyroid function impairment and therefore treatment is restricted to therapy resistant arrhythmias. In the literature scarce data is available on management and therapy of amiodarone induced thyroid dysfunction at a young age. We present three adolescent patients developin...

In CAH due to 21-OH deficiency, phenotype-genotype correlation is known. However, the same genetic events may cause different clinical forms of the disease. A case of CAH associated with the P30L in the CYP21A2 gene in presented. The Caucasian girl was born normally and growing healthy till the age of 3.y., when her mother noticed pubic hair growth; at the age of 4 she had acne and an increasing sweating. At 6 y. of age, she was brought to paediatric endocrinologist f...
