Background: Emotional disorders are serious complications in obese children. Dopamine is known to be one of the neurotransmitters, which is in charge of such conditions.Aim: To determine neuroendocrine and psychological status in obese children.Methods: We examined 296 children in the Endocrinological Department of University Hospital (Minsk); group 1 – 206 obese children (simple obesity: 14.35±2 years; BMI 30.8±2.5 ...

Background: Subclinical hypothyroidism (SH) is defined as normal tyrosine levels in the presence of TSH concentrations between 5 and 10 mU/ml. The impact of SH on IGF system and growth of infants remains unknown.Objective and hypotheses: To evaluate IGF1, IGFBP3 levels and growth velocity (GV) of infants with SH.Method: 98 children up to 36 months of age, recalled due to a TSH >5 mU/ml in the neonatal screening test, were divid...

Background: Turner syndrome (TS) patients typically exhibit short stature and gonadal dysgenesis with pubertal delay and infertility. Up to 30% of these girls will have spontaneous pubertal development, however only 2% achieve a spontaneous pregnancy. Biochemical markers reflecting the ovarian reserve in girls and adolescents with TS are therefore needed.Objective and hypotheses: Evaluation of the ovarian reserve in girls and adolescents with TS using se...

Background: Neurogenic diabetes insipidus (NDI) is extremely rare in the neonatal period. In most cases, it’s secondary to CNS injury. The clinical presentation in this group (particularly in preterm) is unspecific and a high degree of suspicion for the diagnosis is necessary.Objective and hypotheses: Diagnose NDI in a neonate with sodium and diuresis instability.Method: We present a case report.Results:...

Background: One of the crucial aspects of the management of disorders of sex development is the assessment of the risk of malignant transformation of a dysgenetic gonad.Objective and hypotheses: The PCR analysis of germ-cell risk factors as the presence of the TSPY gene may be helpful in decision making of an early gonadectomy.Results: We report a 46,Xdel(Y)p11.3 girl with gonadal dysgenesis, that was referred to the Depar...

Background: C-peptide secretion is the most accurate measurement of residual β-cell function in type 1 diabetes (T1D) and even residual levels seem to positively correlate with a lower probability of complications.Objective and hypotheses: Identify key determinants to the evolution of the β pancreatic cell function, measured by fasting C-peptide (FCP).Method: Prospective study of patients diagnosed with T1D, with evaluati...

Background: The primary source of dietary calcium is often cow’s milk. Previous studies show a reduced bone mineral density (BMD), measured by dual energy x-ray absorptiometry, in children with cow’s milk allergy (CMA). No studies using peripheral quantitative computed tomography (pQCT) to determine bone health have been carried out in subjects with CMA. Long-term effects of a milk elimination diet during infancy on bone health are unknown.<p c...

Background: Vitamin D supplementation is widely recommended to infants, but the optimal dose remains unclear. Vitamin D regulates calcium metabolism, and overdosing and high intake may result in hypercalcemia.Objective and hypotheses: We measured serum pH-adjusted ionized calcium (Ca-ion/pH 7.40) concentrations at 6 and 12 months and 25-hydroxyvitamin D (S-25-OHD) at 12 months in order to evaluate the risk of hypercalcemia during vitamin D3 su...

Background: Main concerns of Congenital Adrenal Hyperplasia Newborn Screening (CAH-NBS) are the high false-positive results (FPR) rate, low positive predictive value (PPV) and heterogeneity of confirmatory tests. Considering the CAH-NBS implementation in our country, our.Objectives: Objectives are to optimize the Neonatal 17OH-Progesterone (N17OHP) cutoffs and to evaluate the best serum confirmatory test.Methods: 473 983 newborns w...

Background: Kallmann syndrome (KS) is a rare clinical entity, characterized by the association of hipogonadotropic hypogonadism and hypo/anosmia, with an estimated prevalence of 1:8000 in males and 1:40 000 in females.Method: Retrospective study of cases of KS diagnosed in paediatric age. Genetic analysis was performed by PCR and DNA sequencing of KAL1, FGFR1, GNRHR, GNRH1, PROK2, PROKR2, KISS1R, TAC3, TACR3, and FGF8 genes.Results...
