Aim: Gonadotropin-releasing hormone analogues (GnRHa) are widely used in the treatment of idiopathic central precocious puberty (ICPP) cases due to premature maturation of the hypothalamus-pituitary-gonad axis. The effect of GnRHa therapy on body weight and fat distribution is controversial in the literature. We aimed to examine the anthropometric measurements and body composition analysis of the girls with ICPP and to investigate the effect of related factors...

Introduction: Osteogenesis imperfecta (OI) is a disease related to collagen synthesis or fuctions. Collagen is found in many areas of the cardiovascular system. Endotelial dysfunction can be detected at an early stage before the symptoms become evident by non-invasive radiologic methods such as flow-mediated dilatation (FMD), carotid intima-media thickness (CIMT), and ventricular functions measurements, which may serve as indicators of endothelial dysfunction....

Introduction: Rate of weight gain during early childhood may have an effect on timing of puberty in girls. Biological mechanisms underlying this condition are not fully understood. Studies examining this association in boys report contradictory results. Our aim was to examine the effects of growth rate during the first years of life on the onset of puberty both in girls and boys.Description of methods: 159 children aged between 6 and 9 years who were att...

Background: Gonads containing adrenal rests may enlarge in response to chronic overstimulation by ACTH in diseases with ACTH hypersecretion such as poorly controlled congenital adrenal hyperplasia (CAH), Addison’s disease and Nelson’s syndrome. Testicular adrenal rest tumors (TART) are present in childhood in CAH patients and frequency in adults may be up to 50–95%. Ovarian adrenal rest tumors (ART) are less frequently detected. TART is decribed less in patients...

Background: Nonclassical congenital adrenal hyperplasia (NCAH), which is generally presented with symptoms of androgen excess, is inherited autosomal recessive due to different kind of mutations in the CYP21A2. Recently, high frequency of copy number variations at CYP21A2 gene and predisposition of heterozygous duplicated CYP21A2 for de novo gene aberrations has been reported.Objective and hypotheses: To evaluate clini...

Pseudohypoparathyroidism (PHP) is a disorder of hormone resistance characterized by end-organ resistance to the actions of parathyroid hormone (PTH). The resistance primarily occurs in the renal proximal tubule, thus leading to hypocalcemia, hyperphosphatemia, and elevated serum PTH. Indicating the resistance in this tissue, patients with PHP show blunted phosphate excretion in response to exogenously administered PTH. In PHP type I, the patients additionally demonstrate blunt...

Endochondral bone formation regulates bone growth both during embryonic development and after birth. Several different autocrine/paracrine or hormonal mechanisms govern the regulation of endochondral bone formation. Among those is the pathway involving stimulatory G protein, which primarily mediates the actions of parathyroid hormone-related peptide (PTHrP) in the growth plate. PTHrP is synthesized in the perichondrial cells and chondrocytes at the end of bones. In the growing...

Background: Turner syndrome is one of the most common chromosomal disorders and is seen in 1:2500 female live births. The disease manifests with various clinical features and can be classified according to karyotype as monosomy, mosaicism, numeric, and structural abnormalities.Objective and hypotheses: Patients with Turner syndrome have complicated with various manifestations congenital or acquired. In this study we aimed to emphasise the importance of a...

Background: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population specific growth charts for TS.Objective and hypotheses: Considering national and ethnic differences, we undertook this multicentered collaborative study to construct growth charts and reference values for height, weight, and BMI from birth to adulthood for spontaneous growth of Turkish girls w...

Background: Turner syndrome (TS) can manifest with various clinical features depending on the karyotype and the genetic background of affected subjects.Objective and hypotheses: The aim of this study was to evaluate growth parameters from birth to adulthood in girls with TS in a cross-sectional study.Method: A total of 842 patients, with an age of diagnosis ranging from birth to 18 years followed-up between 1984 and 2014, from 35 d...
