Background: Van Wyk–Grumbach syndrome (VWGS) is characterized by breast development, uterine bleeding and multi-cystic ovaries in the presence of long-lasting primary hypothyroidism.Objective and hypotheses: The pathophysiology of VWGS involves a complex mechanism, which is at least partly mediated by the direct action of TSH and FSH receptors.Method: We present a girl with Down syndrome having typical feature...

Introduction: Hyperinsulinemic hypoglycemia is one of the most common causes of severe and persistent hypoglycemia in neonates and children. Early diagnosis and appropriate treatment prevent brain damage due to recurrent hypoglycemia. Genetic examination often can guide the treatment. The most common affected genes are the ABCC8 and KCNJ11 genes, which encode the SUR1 and Kir6.2 KATP channels, respectively. Here, a neonate with a novel variant in AB...

The stimulants that the mother is exposed during pregnancy may affect the baby in the future. Electromagnetic field exposure is an important external stimulus that we are subject to. In addition to the interaction of the earth and the sun with the magnetic field of man; nowadays the intensive use of electrical appliances, computers, mobile phones and internet, how electromagnetic field exposure may affect future generations will only occur in the continuation of our generation...

Background: Prohormone convertase is an enzyme that converts many biologically inactive prohormones into biologically active peptides. Its deficiency is characterized by deficiency of variable levels in all the hormone systems. In relation to this, postprandial hypoglycemia has been reported but, a case of prohormone convertase deficiency presenting with a diagnosis Type 2 diabetes mellitus has not been previously reported.Case p...

Introduction: Noonan Syndrome (NS) is a heterogeneous group of diseases with a genetic etiology affecting the RAS/MAPK signaling pathway known as RASopathy. Genes known to cause NS are PTPN11, KRAS, SOS1, RAF1, BRAF, SHOC2 and RIT1. There are sufficient studies indicating that recombinant growth hormone (rhGH) therapy can be given without increasing risk of developing cancer in NS cases with PTPN11 mutations from different centers. In this study, it was aimed ...

Introduction: Vitamin D-dependent rickets type 2A (VDDR2A) is a rare autosomal recessive disease that caused by mutations in the vitamin D receptor (VDR) gene. Hypocalcemia, high alkaline phosphatase, secondary hyperparathyroidism, high 1.25-OH vitamin D (1.25-OHD) levels despite normal 25-OH vitamin D (25-OHD) levels are diagnostic. The clinical signs are rickets, short stature, recurrent lung infections and total/subtotal alopecia. Here, we present a case of...

Introduction: Gonadotropin releasing hormone analogs(GnRHa) have been used safely for many years in the treatment of central precocious puberty(CPP).Although rare; pain, swelling, erythema at the injection site are known local side effects in patients receiving GnRHa treatment and are temporary.Sterile abscess(SA) development is also one of the rare local side effects.We presented three cases of treatment failure due to the development of SA after GnRHa therap...

Background: Graves' disease is a rare autoimmune disorder in children. Its incidence is 0.1/100,000 person-years in young children and 3/100,000 person-years in adolescents. It is related to the production of TSH-stimulating autoantibodies occurring on a particular genetic predisposition. The particularity of Graves' disease in children is the risk of relapse after medical treatment, which is more frequent than in adults with a frequency of around 30...

Objective: The incidence of congenital hypothyroidism (CH) has increased worldwide. Lowering cut-off in screening programs has led to an increase in the rate of transient CH. We aimed to evaluate the rates of permanent and transient CH in cases referred from the screening program and to investigate the clinical and laboratory factors to predict the transient CH.Methods: 109 cases referred from the screening program to ou...

Introduction: IMAGE Syndrome (#614732) is an autosomal dominant inherited syndrome as a result of CDKN1C mutation characterized by the association of intrauterine growth retardation, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies. Here, long-term follow-up of a case with clinical IMAGE syndrome, no genetic mutation was detected, will be presented.Case: A three-month-old baby boy was brought wi...
