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: WAGR syndrome was first described in 1964 by Miller et al. And is characterized by Wilms tumor, aniridia, genitourinary anomalies, and developmental delay. Endocrine/metabolic problems (obesity, dyslipidemia, hypertension, short stature), especially obesity, are seen in more than 70% of cases with WAGR syndrome. Here, we aimed to present a case with WAGR syndrome for endocrine evaluation.Case: A 12...

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...

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...

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...

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 ...

Background: Thalassemia major is a hemoglobin disorder characterized by regular transfusion requirement. Despite the regular transfusions and advanced iron chelation protocols, endocrine complications have been reported as the frequent morbidities of the disease.Objective and hypotheses: The aim of the study was to i) investigate the prevalence of endocrine complications, ii) to examine the relationship between endocrine complications and metabolic param...

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...
