Key words: early puberty, mood change, GnRH analogueIntroduction-Aim: In cases with early puberty, neuroendocrine, physical, and psychological changes are considered to result in several mood disorders. The aim of this research was to assess the mental problems of pubertal girls with rapidly progressive puberty (RPP) with menarche before the 10 years of age. To the best of our knowledge, there is no similar prospective c...

Background: Thyroid cancer is a very rare malignancy of childhood. Approximately they account for 1.5% of all cancers before 15 years of age. In our country, this rate is %0.4 before 20 years of age.Aims and objectives: To analyses the clinical features and treatment results of children with thyroid malignancy in Turkey.Methods: In this multicentric and retrospective study the demographic and clinical characteristics of 124 childre...

Background: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population specific growth charts for TS.Objective and hypotheses: Considering national and ethnic differences, we undertook this multicentered collaborative study to construct growth charts and reference values for height, weight, and BMI from birth to adulthood for spontaneous growth of Turkish girls w...

Background: Adrenocortical carcinoma (ADCC) is a rare cancer in children and differs significantly in epidemiology, clinical characteristics, and biologic features from their counterparts in adults. Germline mutations of the TP53 tumor suppressor gene are associated with cancer predisposition in families with the Li-Fraumeni syndrome.Aim: To report a young girl with family a history of ADCC who presented with severe virilisation secondary to ADC...

Background: Adrenal insufficiency is an important and potentially life-threatening condition, and it is also known as a rare cause of hypercalcaemia.Objective and hypotheses: Resistant hypercalcemia may be associated with hypocortisolism.Method: A 18-day-old male infant was born at 36 weeks by emergency cesarean section for fetal distress and intrauterine growth retardation. He was referred to paediatric endocrinology because of th...

Objective: Glioblastoma 2 (encoded by GLI 2 gene), is an activating zinc-finger transcription factor, involved in the Sonic Hedgehog pathway and embryogenesis of diencephalon and distal extremities Heterozygous mutations of GLI2 gene cause a wide range of clinical phenotype known as holoprosencephaly and holoprosencephaly-like syndrome, pituitary insufficiency, mid-facial hypoplasia, and polydactyly. We, herein, report a novel heterozygous IV...

Background: Mutations in the 21-hydroxylase gene (CYP21A2) accounts for 90–95% of all congenital adrenal hyperplasia (CAH) cases. There is a strong relationship between genotype and disease severity.Objective: The aim of the study was to investigate the most frequent known mutations in CYP21A2 and to describe the genotype-phenotype correlation in Turkish children with CAH due to 21-hydroxylase deficiency.Methods: Based on clin...

Introduction: Central precocious puberty (CPP) is a condition characterized by early signs of sexual development. Mutations in the MKRN3 gene located on chromosome 15q11.2 are rare but are among the most common causes of familial precocious puberty. Early signs of puberty may occur due to the inability to produce this inhibitory protein normally or due to its malfunction resulting from mutations in the MKRN3 gene. Mutations in the MKRN3 gene follow autosomal d...

Objective: In patients with growth hormone deficiency (GHD), even in those with no major organic lesion, anterior pituitary height (APH) is reported decreased. Limitations in the evaluation of APH and changes according to pubertal status make its validity questionable. Recently, in a small scale study, pons ratio (PR) has been suggested as a more sensitive marker for evaluation of pituitary gland in GHD patients. The study aims to evaluate the validity of PR a...

Objectives: Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disorder characterized with isolated glucocorticoid deficiency. Melanocortin receptor 2 (MC2R) mediates the functions of adrenocorticotropic hormone (ACTH) in the adrenal cortex. MC2R accessory protein (MRAP), a transmembrane protein, involves in the trafficking of MC2R to the cell surface. Mutations in MC2R and MRAP genes cause FGD type 1 and 2. Herein, we ev...
