Background: Childhood is a dynamic process with continuous growth and development. Growth charts are essential for the assessment of children’s health status. Standards previously established in children aged 6–18 years, according to percentile curves are used in Turkey.Objective and hypotheses: To determine the effect of different environmental factors on growth of children with the same genetic origin. We investigated the parameters of growth...

Background: Hypothyroidism is frequently associated with muscular disorders and sometimes with moderately elevated levels of muscle enzymes. On the other hand, neuromuscular manifestations are rarely the only symptoms/signs present. Kocher–Debré–Semelaigne syndrome is a myopathy of hypothyroidism in childhood characterized by muscular hypertrophy. Rhabdomyolysis due to hypothyroidism is very rare. A very high creatinine kinase level in the range seen with inflam...

Background: Boys with 21-hydroxylase deficiency (21-OHD) develop testicular adrenal rest tumors (TARTs) at a high percentage. TARTs may lead to testicular structure damage and infertility. Treatment consists of increasing the glucocorticoid dose to suppress ACTH or surgery when necessary.Objective and hypotheses: We present an adolescent with TART who was treated by testicular sparing surgery at the age of 11.Method: A 13 -year-old...

Background: Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterized by susceptibility to tumours including haemangioblastomas of retina and central nervous system, renal cell carcinoma and phaeochromocytomas. The disease is caused by mutations in the VHL tumour suppressor gene.Objective and hypotheses: We present an adolescent with VHL disease confirmed by genetic analysis which revealed the mutation p. A149P (PCC>GCC), which ...

Background: Intrathyroidal ectopic thymus (IET), a benign lesion due to aberrant thymic migration during embryogenesis, is often discovered incidentally. Most of the reports in the literature describe individual cases or small series. We aimed to present the ultrasound (US) features, diagnostic methods, and follow-up of IET in children and adolescents.Methods: We searched our database of patients under 18 years old with ...

The aim of this study was to investigate the clinical and laboratory features of patients who received recombinant human growth hormone (rhGH) treatment and to investigate the factors that determine the response to rhGH treatment. The clinical features of children treated at least one year with rhGH were retrospectively analyzed. Patients were grouped according to diagnosis; isolated GH deficiency (IGHD), multiple pituitary hormone deficiency (MPHD), Turner s...

Background: Assessment of beta-cell function in type 1 diabetes (T1D) has important implications in both clinical and research settings. Studies are limited by the lack of adjustments demonstrating the extent to which puberty influences C-peptide levels. The aim of this study was to evaluate the influence of pubertal stage as well as age and body mass index (BMI) on multiple C-peptide measures at T1D diagnosis.Methods: T...

Objective: The aim of this study was to evaluate demographic characteristics; clinical, laboratory, imaging features; and response to treatment of boys who were followed up and treated with the diagnosis of central precocious puberty (CPP) in Turkiye.Materials and Methods: The study was planned as a multicenter, retrospective study. Cases with a diagnosis of CPP, whose follow-up data were available were included. Patient...

Increased glycemic variability is an important risk factor in terms of complications independent of HbA1c. The aim of this study was; to investigate the relationship between continuous glucose monitoring system (CGMS) indices and clinical data, to investigate DNA damage in patients with diabetes and to evaluate the effect of glycemic variability on DNA damage. Fifty patients with T1DM, aged under 18 years old, who were followed up at least one year in Pediatric Endocrinology D...

Background: Thalassemia major is a hemoglobin disorder characterized by regular transfusion requirement. Despite the regular transfusions and advanced iron chelation protocols, endocrine complications have been reported as the frequent morbidities of the disease.Objective and hypotheses: The aim of the study was to i) investigate the prevalence of endocrine complications, ii) to examine the relationship between endocrine complications and metabolic param...
