Background: Monogenic defects are among the significant causes of early-onset non-syndromic severe obesity in childhood. Identifying the genetic cause of obesity can guide for treatment. The aim of our study is to investigate the clinical and biochemical features of patients with early-onset severe obesity and evaluate the underlying molecular diagnosis.Materials and Methods: A total of 39 patients (M/F: 22/17) with non-...

Aim: 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a lipokine secreted from brown adipose tissue, and it is shown to have positive effects on dyslipidemia. Acute exercise have been shown to lead to an increase in its secretion. It was aimed to investigate the relation of 12,13-diHOME with obesity, exercise and dyslipidemia for the first time in the adolescent age group.Methods: This is a prospective study includ...

Background/Aim: Gender identity disorder (GID) is a condition, which is characterized by incongruence between experienced gender and the natal-sex, which also causes deterioration of functionality. After psychiatric evaluations, medical treatment for adolescents with GID consists of 3 phases. First phase is the suppression of puberty with GnRH-analogues, which may be considered to be supporting the diagnostic process. In the second phase, cross-sex steroid hor...

Background: Osteoporosis-pseudoglioma syndrome (OPPG), rare autosomal recessive entity, is characterized by juvenile osteoporosis, bone deformities, neuromotor retardation, and congenital blindness. This syndrome is due to the loss-of-function mutation in LRP5 (Low-density lipoprotein receptor-related protein 5). Here report four cases from three families, with confirmed molecular diagnosis who showed improvement of osteoporosis improved with biphosphonate therapy.<p class...

Introduction: Rate of weight gain during early childhood may have an effect on timing of puberty in girls. Biological mechanisms underlying this condition are not fully understood. Studies examining this association in boys report contradictory results. Our aim was to examine the effects of growth rate during the first years of life on the onset of puberty both in girls and boys.Description of methods: 159 children aged between 6 and 9 years who were att...

Background: Gonads containing adrenal rests may enlarge in response to chronic overstimulation by ACTH in diseases with ACTH hypersecretion such as poorly controlled congenital adrenal hyperplasia (CAH), Addison’s disease and Nelson’s syndrome. Testicular adrenal rest tumors (TART) are present in childhood in CAH patients and frequency in adults may be up to 50–95%. Ovarian adrenal rest tumors (ART) are less frequently detected. TART is decribed less in patients...

Background: Although thyroid nodules are rare in children compared to adults, the risk of malignacy is higher. Thyroid fine-needle aspiration (FNA) is a reliable diagnostic method used in the prediction of malignancy in the evaluation of thyroid nodules together with clinical and ultrasonographic findings.Objective and hypotheses: To compare clinical, ultrasonographic, cytological and histopathological findings in patients who underwent FNA.<p class=...

Introduction: Growth hormone (GH) treatment is used to accelerate growth in patients with Turner syndrome (TS). During treatment, evaluation of IGF-1 is strongly recommended for efficacy and safety. Some patients, despite optimum GH doses, have persistent high IGF-1 levels. In this study, we aimed to evaluate the relationship between IGF-1 levels, IGF1R and growth responses of TS patients on GH treatment.Method: 54 patie...

Background: Type 1 diabetes (T1D) is characterized by chronic hyperglycemia and microvascular complications like retinopathy, nephropathy, and neuropathy in long term. Nailfold video capillaroscopy (NVC) is a non-invasive method used to examine the microcirculation in the skin. In this study, we aimed to evaluate the microvascular structure in T1D with NVC, observe capillaroscopic alterations, and reveal the relationship of capillaroscopic abnormalities with g...

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...
