Objectives: We describe 5 pedigrees with a novel phenotype including GHD associated with primary ovarian insufficiency (POI) and investigate the underlying molecular basis.Patients and Methods: 6 Turkish patients (5F, 1M) born to 5 consanguineous pedigrees with severe GHD were identified. All females had POI; the male had normal puberty. All had severe postnatal growth retardation (height -4.4 to -8.9 SDS at presentation...

Gender uncertainty is stressful condition for children and their families. Gender assignment in children with disorder of sex development (DSD) is considered as a medical emergency. Influencing factors to consider when debating gender assignment include medical diagnosis, external genital appearance, potential of fertility and sexual, therapeutic and/or surgical intervention options, views and desires of patients and families, situation of social-cultural factors, the psycholo...

Background: 3β-hydroxysteroid dehydrogenase (3βHSD) deficiency is a rare form of congenital adrenal hyperplasia (CAH) and caused by loss of function mutations in the HSD3B2 gene. In classic form, affected patients have salt wasting early in infancy and may have ambiguous genitalia in both sexes. Herein we report a nonvirilized female patient with classic form of 3βHSD deficiency due to homozygous S218P mutation in the HSD3B2 gene and classic phenylketonuria....

Introduction: Monogenic obesity refers to a group of rare, early-onset forms of obesity and accounts for about 7% of patients with severe pediatric obesity. Recent reports demonstrate the emerging role of Src-homology-2 (SH2) B adaptor protein 1 (Sh2b1), an important component in the leptin-melanocortin pathway, as a key regulator of leptin and insulin signaling, with possible roles in the pathogenesis of obesity and diabetes. SH2B1 deletions are found to be a...

Introduction: It is thought that long-term growth hormone (GH) treatment may impair hepatic glucose production and insulin-dependent glucose utilization, and therefore it is attributed that GH may adversely affect glucose metabolism.Objective: In our study, we aimed to examine the effects of GH treatment on insulin sensitivity and glucose metabolism in patients with GH deficiency after 1-year of treatment.<p class="a...

Introduction: The frequency of solid and hematological malignancies has been reported to be higher in children with Turner syndrome than in the general population. Mycosis fungoides (MF) represent the most common type of cutaneous T-cell lymphoma, which is a low-grade lymphoproliferative disease. To the best of our knowledge, the coexistence of Turner syndrome and MF has not yet been reported. Here, we report a girl with Turner syndrome and MF.<p class="ab...

Introduction: Fulminant type 1 diabetes (FT1D) occurs because of a sudden and almost total destruction of pancreatic β-cells, triggered by a viral infection. FT1DM may cause diabetic ketoacidosis (DKA) and even sudden death. Thus prompt diagnosis is vital.Case Report: Antibiotic treatment was started for a 4-year-old female patient because of a fever and cough. On the second day of treatment, she was admitted with r...

Background: Osteonecrosis (ON) is bone death caused by inadequate blood supply resulting in demineralization and trabecular thinning and, subsequently, mechanical failure. Although the pathophysiology of ON is not fully understood, the use of high-dose glucocorticoid (GC) is one of the triggers. Furthermore, its optimal management remains uncertain. The use of bisphosphonates (BP) for the treatment of ON has been reported, however, data on outcomes are limited...

Background: Thyroid cancers are rare in childhood. ATA guideline (Pediatric section) has been applied in daily practice since 2015. It is very significant to accurately predict the risk in the management of differentiated thyroid cancer(DTC). For this purpose, we shared our single center-20-year-experience about the follow-up features and management of childhood and adolescent thyroid cancer. We aimed to evaluate the dynamic risk stratification (DRS) and the o...

Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...
