Background: Oxidative stress and adipocytokines are associated with obesity.Objective and hypotheses: To investigate the association of adipocytokines with markers of pro- and anti-oxidation at baseline and their change and correlations during acute aerobic exercise in normal weight and obese pre- and early-pubertal boys.Method: Fifty healthy pre- and early-pubertal, normal weight and obese boys, underwent a baseline blood sampling...

Background: The ability to respond to stress constitutes a defensive protective mechanism; both inadequate and excessive responses may be detrimental.Objective and hypotheses: To investigate the effect of increased body weight on the hormonal response to stress in children. Scheduled surgical procedures include two stressful parts, a psychological one (anticipation of operation) and a biological one (surgical stress per se) and were chosen as a study mod...

Background: Nonimmune neonatal goitrous hypothyroidism is a rare cause of neck mass and stridor. Retropharyngeal extension, described in 7% of cases of goitre spreading outside the thyroid bed, represents a diagnostic dilemma that requires a systematic multimodality imaging approach combined with hormonal and genetic analysis. We report the case of a one-week-old baby who presented with stridor and respiratory distress, without palpable neonatal goitre and whose biochemical pr...

Key words: girls, small for gestational age, thelarche, pubarche, menarche.Background: Small for gestational age (SGA) babies are more prone to have an earlier onset of pubertal development and menarche. We conducted a study comparing the first menarche of small for gestational age (SGA) to appropriate for gestational age (AGA) girl newborns.Objective: The objective of the study is...

Background: Central precocious puberty (CPP) due to premature activation of GnRH secretion results in early epiphyseal fusion and to a significant compromise in the achieved final adult height as well as psychological consequences. So far only a limited number of genetic determinants have been associated with the pathogenesis in children with CPP. In this original research, rare sequence variants in MKRN3, DLK1, KISS1, and KISS1R genes were i...

Background: More than >90% of cases of congenital adrenal hyperplasia (CAH) are caused by 21-hydroxylase deficiency, steroid 11β-hydroxylase deficiency accounts for 5–8% of cases.Objective and hypotheses: To seek evidence on the prevalence of CYP11B1 mutations in prepubertal girls, adolescents and adult females with clinical signs of hyperandrogenemia.Method: The study included 31 girls with premature adrenar...

Background: Congenital Adrenal Hyperplasia (CAH) is an autosomal recessive disorder with more than 90% of cases caused by defects in the steroid-21 hydroxylase (CYP21A2) gene. Such defects are the main cause of 21-hydroxylase enzyme deficiency that affects the biosynthesis of cortisol and aldosterone. The CYP21A2 gene is part of the RCCX module, which is located on chromosome 6p21.3, in the major histocompatibility complex (MHC) class III reg...

Background: Maternal obesity is known to have many detrimental effects on pregnancy. Bariatric surgery represents the most efficient therapy for severe obesity. Although it is known to positively impact many pregnancy outcomes, bariatric surgery can disturb fetal growth due to nutritional deficiencies.Objective: We aim to examine the repercussions of bariatric techniques on fetal growth, and to evaluate the risk of deliv...

Bariatric surgery represents the most efficient therapy for severe obesity. Although it is known to positively impact many pregnancy outcomes, bariatric surgery can disturb fetal growth due to nutritional deficienci...

Keywords: Preterm newborn, Small for gestational age, Thyroid hormones, Thyroid-stimulating hormone, Thyroid dysfunctions, Thyroid function tests.Background: A common cause of neurodevelopmental impairment in children is congenital hypothyroidism, but can be preventable with adequate screening and proper management. Preterm newborns are more likely to have thyroid dysfunction, with small for gestational age (SGA) being a...
