Background: In 2012, a phenomenon of early isolated gonadotropin-independent thelarche among contemporary girls was reported.Objective and hypotheses: We wanted to evaluate whether a contemporary isolated early pubarche also exists. One way of looking into this is by investigating the age of pubarche in a group of girls with premature pubarche (PP) over time. If some girls had earlier pubarche, then, we would expect a subgroup (i.e. those younger than 8 ...

Background: Thyroid nodules are less common in childhood but it has higher risk of malignancy. In this study, we aimed to evaluate children and adolescents with thyroid nodules, clinically, radiologically and histopathologically to determine etiologic distrubution.Method: Seventy-one patients (46 females) with the mean age of 10.41±5.03 (0.04–21) years with thyroid nodules were involved in this study. Patients were evaluated by their complaints...

Objectives: We aimed to evaluate the performance of lipid accumulation product (LAP) to predict non-alcoholic fatty liver disease (NAFLD) in obese children.Methods: Eighty obese chidren (39 girl) were included in this study (6–18 years). Height, weight, body mass index (BMI), waist circumference (WC), puberty stage, blood pressure (n=28), fasting glucose, fasting insulin, HOMA-IR, alanine aminotransferase (ALT), aspartate aminotransferase (...

Background: Vitamin D dependent type 1 rickets is a rare, autosomal-dominantly inherited disorder due to an inactivating mutation in CYP27B1 (25-OH vitamin D-1-α-hydroxylase) gene. It is characterized by early onset of rickets with hypocalcemia. We report a boy admitted with symptoms of hypocalcemia and who carried a novel mutation in CYP27B1 gene.Case: The patient was admitted with tetany at the age of 12 months. When he had his first convulsion, h...

Background: Corticosterone methyloxidase deficiency (CMOD) type 2 is an autosomal recessive disorder which presents with salt loss and failure to thrive in early childhood. We present three siblings with CMOD type 2 whose genetic analyses revealed a known c.1175T>C mutation (homozygous) and a novel c.788T>A mutation (homozygous) in CYP11B2 gene.Case 1: The patient was admitted with salt loss and failure to thrive at the age of 6 months; ...

Background: It is well-known that human GH (hGH) treatment increases growth rate in idiopathic short stature (ISS) in the short term which might predict the overall height gain. However,the fact that ISS might involve a heterogeneous group of individuals with individual benefits from hGH treatment makes the decision to treat or not to treat difficult.Objective and hypotheses: The aim of this study was to investigate retrospectively whether an IGF1 genera...

Background and objective: 21alpha-hydroxylase deficiency congenital adrenal hyperplasia (21OHD-CAH) is the most common etiology of inherited primary adrenal insufficiency (PAI) in children. Neonatal CAH screening is important for early diagnosis of salt-wasting 21OHD and other virilizing CAH (11beta-hydroxylase, 3beta-hydroxysteroid dehydrogenase deficiencies) and for avoiding mortality, especially in salt-wasting CAH. Neonatal CAH screening has become nationw...

Background: Pheochromocytomas and paragangliomas (PPGLs) are rare pediatric neuroendocrine tumors. Data on the diagnosis, treatment and follow-up of PPGL in children are limited and lack standardization. Furthermore, variations in access to diagnostic and therapeutic resources across centers contribute to inconsistencies in clinical management.Aim: To identify variations in the clinical management of paediatric PPGL with...
