Background: Hypoparathyroidism is a rare disease characterized by inadequate parathyroid hormone (PTH), resulting in hypocalcemia and hyperphosphatemia. Hypoparathyroidism can be transient, inherited, or acquired, and is caused by inability to synthesize or secrete PTH, abnormal parathyroid gland development, destruction of parathyroid tissue, or peripheral resistance to PTH.Methods: Medical records from 20 children and adolescents diagnosed with hypopar...

Background: Seeking strict normoglycemia in type 1 diabetes mellitus increases the risk of hypoglycemia, exposing to hypoglycemia unawareness. Hypoglycemia unawareness (HU) is defined as the occurrence of hypoglycemic symptoms directly without autonomic symptoms. This study is designed to determine the incidence of HU in children and adolescents with continuous subcutaneous glucose monitoring system and to assess the effect of structured education to improve awareness.<p c...

Background: Papillary thyroid cancer (PTC) constitutes more than 90% of the thyroid cancer in children. PTC behaves differently in prepubertal children than in pubertal children and between children and adults. BRAF gene activating mutations lead to PTC by creating aberrant activation. The most common mutation is BRAFV600E.Objective and hypotheses: To evaluate clinicopathological characteristics of PTC patients with emphasis on the pubertal st...

Background: 45,X/46,XY mosaicism is associated with a broad spectrum of phenotypes, ranging from ambiguous genitalia at birth to patients with a completely male or female phenotype. Turner syndrome stigmata and associated anomalies could be found in these patients.Objective and hypotheses: To evaluate clinical presenting symptom and follow-up data of 30 patients with 45,X/46,XY karyotype.Method: Thirty patients with 45,X/46,XY mosa...

Background: The melanocortin-4-receptor gene (MC4R) is a key regulator of energy homeostasis, food intake, and body weight which has intensively been analysed in molecular genetic obesity research. MC4R dysfunction in humans causes hyperphagia, impaired satiety and obesity. Most patients are heterozygotes, with some reports of homozygotes and compound heterozygotes.Objective and hypotheses: A 2-year-old boy with progressive weight gain from infa...

Introduction: Turner Syndrome (TS) is known to be associated with a high risk of cardiac anomalies and cardiovascular diseases. Detailed cardiac evaluation at diagnosis and serial evaluation for dissection is warranted.Aim: This study aimed to evaluate TS patients for cardiac pathology using MRI.Methods: Clinical findings, karyotypes, echocardiogram results, cardiac MRI findings of 33 patients with TS were evaluated. Measurements o...

Background: Aromatase excess syndrome (AEXS) (OMIM 139300) is a rare condition characterized with gynecomastia in boys and macromastia in girls. Estrogen excess in boys can lead to prepubertal and pubertal gynecomastia, bone age progression and short adult stature. While most of girls are usually asymptomatic, there are few reported female patients with excessive breast growth, early puberty, menstrual irregularities, and short adult stature. Male and female children with AEXS...

Aim: Data on response to GH treatment in the very young children with GH deficiency is scarce. The aim of this study was to evaluate the growth response in such children in a national multicentre study and to analyse the factors affecting the growth response.Materials and methods: In this study, we retrospectively evaluated the files of GH deficiency patients who had started GH treatment between 0–3 years of age who were being followed in 14 differe...

Background: Hereditary hypophosphatemic rickets with hypercalciuria(HHRH; OMIM: 241530) is a rare autosomal recessive disorder,which is the result of loss-of-function mutations in the sodium-phosphate-cotransporter NPT2c.This disorder is characterized by renal phosphate(Pi) wasting,hypercalciuria,increased 1,25 (OH)2-D levels and decreased parathormone(PTH) levels.Here we report the clinical features of two siblings with HHRH,confirmed with molecula...

Introduction: Skeletal dysplasia is a heterogeneous group of disease, leading to abnormal enchondral ossification and typing of the disease is quite complex. C-type natriuretic peptide (CNP), one of the members of the natriuretic peptide family, has been implicated to play a role in bone development. CNP levels were high in some types of the skeletal dysplasia.Objective: The aim of this study is to evaluate the possibility of using CNP, as a marker for s...
