Background: C1q/tumor necrosis factor-related proteins (CTRPs) are the recently recognized members of the adipokine family, secreted from adipose tissue. Some types of CTRPs, including CTRP-13, play an important role in energy metabolism in humans. Also, CTRP-13 was found as an anorexigenic factor in experimental studies.Objective: We aimed to investigate serum CTRP-13 levels in obese and healthy children, as well as the...

Background: Resistance to thyroid hormone alpha (RTH-α) is characterized by varying degrees of symptoms and findings related to hypothyroidism. However, diagnosis is difficult since thyroid-stimulating hormone (TSH) levels are normal. Free triiodothyronine (fT3) and free thyroxine (fT4) levels can also be normal, but normo- or macrocytic anemia is generally present in the reported cases. L-thyroxine can alleviate some symptoms; however, there is limited ...

Background: The etiology of infantile colic is unknown. Its timing overlaps with that of minipuberty. To the best of our knowledge, the relationship between these entities has not been investigated. In this study, we aimed to assess the relationship between minipuberty and infantile colic by measuring the levels of sex steroids in saliva among infants with and without infantile colic.Methods: Saliva samples were collecte...

Introduction: Gynecomastia is common in boys at early-mid puberty, while prepubertal gynecomastia is a rare condition. Sertoli cell tumors (SCTs) account for 2% of prepubertal testicular tumors. Most of the SCTs in prepubertal boys, which are generally bilateral and diffuse, are in the content of Peutz-Jeghers Syndrome (PJS) or other familial syndromes (Carney complex). Large cell calcifying Sertoli cell tumor (LCCSCT) is a variant of SCT and is seen in PJS. I...

Background: Recently, T3 receptor alpha (TRα) mutations have been identified in a number of patients with varying degrees of growth impairment, delayed development, constipation, increases in serum T3 and decreases in T4 and rT3.Objective: To determine the spectrum of clinical and functional consequences of novel TRα mutations.Method: Clinical assessment and biochemical, imaging...

Background: No large study comparing efficiency of prednisolone, alendronate and pamidronate has been conducted so far in children with hypercalcemia due to vitamin D intoxication.Objective and hypotheses: To perform a multicentre, retrospective study assessing clinical characteristics and treatment results.Method: A standard questionnaire was uploaded to an online national database system (www.favorsci.org) to collect data of chil...

Introduction: Aromatase inhibitors (AIs) are increasingly used in children and adolescents to augment adult height. Given the potential risks of these drugs in women with breast cancer, detailed cardiovascular examinations in adolescents using these treatments are needed to ensure their safety in the pediatric group. The aim of this study was to investigate the effects AIs on cardiac morphology, functions and their relation to several metabolic parameters in a...

Purpose: The aim of the present study was to determine the efficiency of three different predictive models [Bayley-Pinneau (BP), Roche-Wainer-Thissen (RWT), and Tanner-Whitehouse 2 (TW2)] by comparing their predictions with near-adult height (NAH) data of girls who received gonadotropin-releasing hormone agonist (GnRHa) therapy.Methods: Clinical findings were retrospectively analyzed. Bone age (BA) was determined by thre...

Background: Osteonecrosis (ON) is bone death caused by inadequate blood supply resulting in demineralization and trabecular thinning and, subsequently, mechanical failure. Although the pathophysiology of ON is not fully understood, the use of high-dose glucocorticoid (GC) is one of the triggers. Furthermore, its optimal management remains uncertain. The use of bisphosphonates (BP) for the treatment of ON has been reported, however, data on outcomes are limited...

Introduction: Homozygous leptin (LEP) and leptin receptor (LEPR) mutations lead to childhood-onset obesity due to deficient leptin signaling. The specific aims of this work are to explore genotype/phenotype correlations in a national multicenter cohort of 18 subjects with leptin (LEP) and leptin receptor (LEPR) deficiency, report on the long-term clinical follow-up of these rare cases, and systematically review all patients with pathogenic <e...
