Background: Estrogen is an essential regulator of bone maturation, growth plate fusion, and cessation of longitudinal growth. Aromatase inhibitors (AI) block the conversion of androgens to estrogens, and can be used to delay bone maturation in males.Objective and hypotheses: We sought to determine whether the blockage of estrogen biosynthesis due to the use of the AI Anastrazole increases the Predicted Adult Height (PAH) in boys with short stature.<p...

Aim: To examine offspring of patients with simple obesity. To ascertain, if there are some disturbances in the carbohydrate or lipid metabolism or unknown type 2 diabetes in these subjects.Method and subjects: Examined were 132 families, 108 families with obesity, and 24 families without obesity, the control group. 14 additional were excluded because of ascertained at the time of examination unknown type 2 diabetes in the parents. In all of the offspring...

Introduction: Short stature is one of the most common reasons for children presenting to an endocrinologist. In normal conditions, growth hormone (GH) stimulates the IGF-1 production in hepatocytes via the STAT5 signaling pathway. Approximately 40% of children diagnosed with idiopathic short stature (ISS), i.e. with normal GH secretion, have a reduced IGF-1 level for unknown reasons. Recently, it has been described that there are certain factors that reduce IG...

Introduction: Noonan syndrome (NS) is relatively common genetic disorder caused by mutations in the PTPN11 (50%), SOS1 (10-13%), and RAF1 (3-17%) genes responsible for disturbances in the activation of the RAS/MAPK signaling pathway. NS is characterized by facial dysmorphic features (90%), congenital cardiac disturbances and short stature (<3c) - the average final adult height is 162.5 cm for male and 153 cm for female. In some, but not all of the NS patien...

Background: Hypopituitarism is characterized by deficiency of one or more anterior pituitary hormones. POU1F1 mutations are the second most frequent known cause of combined pituitary hormone deficiency (CPHD). Patients are typically deficient in GH, TSH, and prolactin, although two unrelated cases were reported with isolated GH deficiency (IGHD). To date, all POU1F1 mutations have been reported for the predominantly expressed alpha isoform, which is a transcr...

Background: NSIAD is a rare genetic cause of hyponatremia, due to activating mutations in AVPR2 gene, encoding the Arginine Vasopressin Receptor Type 2, and located on Xq28. Of the fewer than 30 reported cases, most have been managed with fluid restriction and urea.Objective and hypotheses: Illustration of the presentation of a family with this genetic abnormality and approach to management.Method: The clinical, biochemical and gen...

Background and Objectives: Enlargement and cystic changes in ovaries of patients with longstanding overt hypothyroidism has been observed in numerous case reports. But there is limited data about the effect of subclinical hypothyroidism (SH) on ovarian volume and ovarian cyst formation. We evaluated the relationship between serum thyroid stimulating hormone (TSH) level and ovarian volume and sonographic appearance in prepubertal girls with SH.<p class="abs...

Objectives: To evaluate the effect of combined treatment with GnRH analogue (GnRHa) and recombinant human GH (rhGH) on the linear growth in mid/late pubertal girls at great bone ages with central precocious puberty (CPP) or early and fast puberty (EFP). To investigate the relation between C-type natriuretic peptide (CNP) signaling pathway and GH’s effect on linear growth in these girls. Methods 22 girls were diagnosed as CPP or EFP, whose bone ages were older than 11.5 ye...

Introduction: Few studies have been published comparing the liquid and tablet formulations of L-T4 in pediatric patients, with a short follow-up period. Both formulations seemed to produce a rapid normalization of thyroid fuction with a tendency of a greater TSH inhibition in children taking the L-T4 liquid drops. The aim of our study is to compare the long-term effectiveness and saftey of both liquid and tablet L-T4 therapy in CH patients up to 3 years old via a multicenter s...

Background: Childhood critical period for onset/continuity of obesity with development of significant clinical and metabolic changes, impairing health in adulthood. Metabolic syndrome on rise both in adult and pediatric obese Indian population. Development of impaired glucose tolerance and progress to insulin resistance and other metabolic alterations like hypertension, dyslipidemia, Non alcoholic fatty liver disease are important.Aim: Evaluate insulin r...
