Prader-Willi syndrome (PWS), a multisystem disorder, results of the absence of expression of paternal genes from chromosome 15q11.2-q13; it occurs with the prevalence of 1/10000-1/30000 in different populations. In real clinical practice PWS still remains a challenge for doctors, especially in resource-limited settings. We describe clinical course in 10 pediatric PWS patients (3M; 7F) aged 7,4±3,3 years (1,7÷12,3), all have microdeletion of paternally inherited 15q11....

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...

Background: Hormone-secreting pituitary adenomas in children and adolescents are rare.Methods: We report clinical course, management and outcome of 6 cases diagnoses in 2013-2019.Results: Patients (3M, 3F), aged 9,5 – 16,5 years at referral. In them, 3 ACTH-secreting adenomas (ACTHA) and 3 prolactinomas (PROLA) were recognized. The family history for endocrine tumors was negat...

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...

Turner syndrome (TS) is characterized by partly or completely missing of an X chromosome and variability of clinical signs. We present tree Caucasian mosaic TS girls with unusual clinical course and discuss some literature.Case 1: A girl referred first to paediatric endocrinologist at the age of 8.5 y. for metabolic problems (an excessive weight gain, acanthosis nigricans, impaired glucose tolerance, hyperinsulinemia). The height was not a concern (Media...

Background: Children with rare genetic disorders may have different endocrine problemsObjective and hypotheses: To present 4 paediatric patients (3 M, 1 F) aged 4.3 – 16.9 y.o. (mean age 11±5.5 years) with different genetic syndromes: Pallister-Hall, Holt-Oram, Ellis–van Creveld and Marshall.Method: Retrospective study.Results: Mean age of diagnosis was 5.3±2.7 y.o. All children had growth...

Background: Mixed gonadal dysgenesis (MGD) is a DSD with variations of 45,X/46,XY caryotype and different phenotype.Objective and hypotheses: To describe the features of six patients (three raised as boys and three as girls).Method: The mean patients’ age at the time of the report is 11.7±4.0 years old. Molecular diagnosis was made in utero and confirmed after birth in two boys (for maternal age and because one mother had...
