Introduction: SOFT-syndrome (#MIM 614783) is a rare condition characterized by short stature, onychodysplasia, facial dysmorphism and hypotrichosis caused by POC1A gene mutations. Moreover, severe insulin resistance (IR) and metabolic disorders may also accompany. Hereby, we report two-patients with SOFT-syndrome, who had severe short stature and IR, with a novel POC1A mutation.Case Report: Patient 1 (P1), a 16-month ol...

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...

Key words: Dysgerminoma, gonadoblastoma, virilizationIntroduction: Gonadoblastoma is a rare ovarian tumor composed of sex cord cells and primitive germ cells. Although it is frequently seen in patients with 46,XY gonadal dysgenesis, it is also rarely seen in patients with a 46,XX karyotype. Here, we report a girl with a 46,XX karyotype presenting due to an uncommon cause of virilization, which was caused by bilateral gon...

Introduction: Fanconi anemia (FA) is a genomic instability syndrome associated with congenital abnormalities. Structural anomalies of the central nervous system (CNS), particularly a small pituitary gland, have been published in a few case series. This has been thought to be the cause of the short stature (SS) observed in FA.Methods: A cross-sectional exploratory study was carried out in pediatric patients at the FA Span...
