Objective: Fetuin-A has many different functions due to its ability to bind to different toll-like receptors in different tissues. Working in different groups will contribute to our understanding of the pathophysiology of Fetuin-A. In this study, we aimed to evaluate Fetuin-A levels in obese adolescents and the relationship between Fetuin-A and anthropometric data, insulin levels and high sensitivity CRP(HSCRP). Material and Meth...

Introduction: Policystic ovarian syndrome (PCOS); is an endocrinopathy characterised by overlap of hyperandrogenism and hyperinsulinism and chronic anovulation. Etiopathogenesis is still not clearly defined. Fetuin-A is aserum glycoprotein. It is shown to play regulatory functions in many inflammatory processes. We aim to define the relationship of fetuin-A levels with hyperandrogenism and hyperinsulinism in PCOS patients and study the role in pathophysiology....

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...
