Background: 46,XY DSD occurs as a result of testicular developmental disorders, defect in androgen synthesis or action. Nowadays, the diagnosis of DSD is quite costly and it takes a considerable amount of time due to lengthy hormonal and genetic analysis.Objective and hypotheses: The use of targeted next-generation sequencing of all known genes associated with 46 XY DSD for a fast molecular genetic diagnosis in patients in whom underlying defect of DSD w...

Introduction: CPHD is characterized by impaired production of GH and one or more other pituitary hormones. Genetic defects causing CPHD typically result in insufficient anterior pituitary gland development.Aim: The aim of the study is to determine the genetic etiologies that lead tocombined hormone deficiencies. Todetermine phenotype genotype relationship with or without extra-pituitary anomalies.<...

"Steroidogenic Factor-1" (SF-1); It is encoded by the NR5A1 gene in 9q 33.3 and regulates the transcription of genes involved in steroidogenesis. It is reported that 46 of the variants in this gene constitute 10-20% of XY sex development disorders (DSD). The patient admitted because of a swelling in the left groin at one month old. She was raised as female. Uterus was 12x2.5 mm in ultrasonography and the gonad in the inguinal region was evaluated as testis. She was P...

Introduction: Idiopathic short stature(ISS) refers to children who are short because there is no identifiable defect in the growth hormone (GH)/insulin-like growth factor(IGF) axis and no other endocrine or genetic disorders. The genetic etiology of ISS in children was investigated in this study using targeted next-generation sequencing(NGS).Method: Eighty patients with short stature of unknown etiology were included in ...

Introduction: In cases of disorder of sex development (DSD), the change between the gender assigned at birth and the individual's chosen gender identity can occur especially after puberty.Aim: was to determine the relationship between genetic sex, gender assigned at birth and gender identity, and the importance of molecular diagnosis.Method:154patients older than 14years of ag...

Background: Mucormycosis which is an invasive fungal disease and commonly seen in immunocompromised patients is very rare in the diabetic children.Case report: We present a case with type 1 diabetes with mucormycosis. A 14-year-old male patient was referred to our department due to polyuria, polydipsia, weight loss, headache, altered consciousness, fever, and rhinorrhea. After the diabetic ketoasidosis treatment, left facial paralysis, anisocoria, and pt...

Background: Puberty is a dynamic period of physical growth. Genetic factors, increasing prevalence of adiposity, environmental factors and the widespread presence of endocrine-disrupting chemicals are suspected to contribute to the trend of earlier pubertal onset.Method: The study group consists of 32 girls diagnosed with central puberty precocious. The eating habits and physical activity status were evaluated with a detailed questionnaire. Daily calorie...

Bardet-Biedl syndrome (BBS) is a rare and multisystemic disorder characterized by rod-cone dystrophy, post-axial polydactyly, learning difficulties, renal abnormalities, obesity and hypogonadism. The disorder is genetically heterogeneous. To date, 21 genes present on different chromosomes have been mapped. The most common genes are BBS1 (locus 11q13) and BBS10 (locus 12q21.2). We aimed to report two family with five affected children with typical clinical features of Bardet-Bi...

Introduction: Central Diabetes Insipitus (CDI) results from the inability to secrete ADH secreted by the neurohypophysis system to control water-electrolyte metabolism. In the etiology of CDI many congenital and acquired CNS tumors, infiltrative diseases,infections, autoimmune events, head trauma and idiopathic can be responsible. In this article, a child case with CDI due to intracranial occurence which is very rare in etiology is presented and the approach and follow up are ...

Background: Osteoporosis is very rare in childhood and main reasons are growth retardation, immobilisation, calcium and vitamin D deficiency, long term steroid therapy. There is no concensus about the treatment of children and adolescents with osteoporosis. Biphosphonates have been important in the treatment of osteoporosis.Objective and hypotheses: To evaluate the efficacy and safety of oral alendronate on bone mineral density (BMD) in children and adol...
