Introduction: Subclinical hypothyroidism (SH) is reported up to 20% of obese population and thyroid hormone replacement in these individuals are controversial. In this study, we aimed to determine the effect of thyroid hormones on basal metabolic rate (BMR) in obesity and, thyroid hormone replacement on BMH and weight in obese patients with SH.Method: The study was conducted in 31 obese children (15 of them had subclinical hypothyroidism) admitted to our...

Introduction: Hypophosphatemic rickets is usually due to genetic causes but in rare cases it can develop secondary to MAS, Fanconi syndrome, or oncogenic causes. Oncogenic osteomalacia, also called Tumor-Induced Osteomalacia (TIO), is a rare acquired paraneoplastic syndrome that develops as a result of excessive phosphate loss from renal tubules by FGF23 released from tumour tissue. In addition to the clinical features of rickets, gait disturbances, growth ret...

Introduction: Although the majority of the cases with obesity have a multifactorial etiology, rare monogenic forms of obesity exist. Several genetic disorders have been described that lead to early onset monogenic obesity. Leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), proprotein converting protein subtilisin / kexin-type 1 (PCSK1) and proopiomelanocortin (POMC) are the genetic mutations that have been most frequently shown to cause mono...

Introduction: Kisspeptin is a neuropeptide, encoded by the KISS1 gene, which acts upstream of gonadotropin-releasing hormone (GnRH) neurons and also has a critical role for maturation and function of the reproductive axis. Inactivating mutations of its receptor (KISS1R) cause normosmic isolated hypogonadotropic hypogonadism (IHH). In this report, we aim to present three siblings who have IHH due to novel compound heterozygous KISS1R mutation.Cas...

Introduction: Antithyroid Drugs (ATD) are generally preferred at the onset of treatment with no consensus on the duration of ATD (propylthiouracil, methymasole) treatment Graves disease in children.Objective: Examining the effectiveness of ATD treatment on children and adolescents and determining the risk factors of remission and relapse.Method: A total of 45 cases with ages varying between 1–18 years diagnosed with Graves dis...

Background: P450 oxidoreductase (POR) deficiency is the newest form of congenital adrenal hyperplasia first described in 2004. POR is a protein that transfers electrons from NADPH to all 50 microsomal forms of cytochrome P450. Mutations that cause POR deficiency result in partial deficiency of the enzymes 21-hydroxylase and 17α-hydroxylase. Remarkable clinical features of the POR deficiency are genital ambiguity in both sexes, glucocorticoid deficiency and Antley-Bixler s...

Background: The most prominent clinical feature in patients with Turner syndrome (TS) is short stature.Objective and hypotheses: To assess the effect of GH and pubertal induction therapy on height gain in patients with TS.Method: 58 TS patients with a mean age of 18.9±7.2 years were documented retrospectively. Clinical findings, karyotype, impact of baseline age, dosage, baseline bone age, duration of the GH and pubertal induc...

Background: Screen (TV, tablet, smartphones, internet, video games, PC etc.) addiction is a growing problem in child health. The effect on insulin-glucose metabolism is not well known yet.Objective and hypotheses: To investigate the insulin resistance in screen addicted children.Method: We studied 108 children and adolescents aged 13.72±1.95 years (range 11–17 years). Participants were divided into three groups according ...

Background: There exists no gold standard for adjustment of treatment in congenital adrenal hyperplasia. Clinicians try to avoid over-and undertreatment by considering various indicators. We aimed to investigate the sampling times of 17-hydroxyprogesterone (17-OHP) and the use of sex hormone-binding globulin (SHBG) as a monitoring parameter, the association of which was not studied with clinical features. Materials and Methods: This cross-sectional study inclu...

Background: Various studies, mostly conducted in adults, evaluated the hormonal axis in primary empty sella (PES), and reported different forms of pituitary deficiencies. We report our 10-year experience of pediatric cases with PES, investigating the pituitary function, associated impairments, and responses to treatments.Materials and Methods: We reviewed 10,560 cranial and 325 pituitary magnetic resonance imagings (MRIs) performed in ou...
