Akın Kağızmanlı Gözde , Kırbıyık Özgür , Abacı Ayhan , Böber Ece , Yiş Uluç , Demir Korcan

Background: Resistance to thyroid hormone alpha (RTH-α) is characterized by varying degrees of symptoms and findings related to hypothyroidism. However, diagnosis is difficult since thyroid-stimulating hormone (TSH) levels are normal. Free triiodothyronine (fT3) and free thyroxine (fT4) levels can also be normal, but normo- or macrocytic anemia is generally present in the reported cases. L-thyroxine can alleviate some symptoms; however, there is limited ...

Background: The inactivating mutations of CYP24A1 (OMIM*126065) were first identified in idiopathic infantile hypercalcemia (IH) and named IH-type1 (IH1). However, biallelic mutations were later associated with hypercalcemia at various ages. In our study, we aimed to present the clinical and laboratory findings of our patients who presented with hypercalcemia and were found to have a mutation in CYP24A1.Methods and Resul...

Introduction: There is a complex and multifaceted relationship between antiepileptic drugs (AEDs) and the neuroendocrine system. Thyroid hormone (TH) sensitivity reflects thyroid homeostasis more comprehensively than serum hormone levels. It is clear whether TH sensitivity is associated with the use of AEDs. In this study, the evaluation of thyroid hormone sensitivity is aimed in euthyroid cases treated with antiepileptic drug therapy. In this study, the evalu...

Background: The etiology of infantile colic is unknown. Its timing overlaps with that of minipuberty. To the best of our knowledge, the relationship between these entities has not been investigated. In this study, we aimed to assess the relationship between minipuberty and infantile colic by measuring the levels of sex steroids in saliva among infants with and without infantile colic.Methods: Saliva samples were collecte...

A Rare and Treatable Cause of Prepubertal Gynecomastia: Large Cell Calcifying Sertoli Cell Tumor

Kağızmanlı Akın , Besci Özge , Yüksek Acinikli Kübra , Şeker Gül , Yaşar Elif , Öztürk Yeşim , Demir Korcan , Böber Ece , Abacı Gözde Ayhan

Introduction: Gynecomastia is common in boys at early-mid puberty, while prepubertal gynecomastia is a rare condition. Sertoli cell tumors (SCTs) account for 2% of prepubertal testicular tumors. Most of the SCTs in prepubertal boys, which are generally bilateral and diffuse, are in the content of Peutz-Jeghers Syndrome (PJS) or other familial syndromes (Carney complex). Large cell calcifying Sertoli cell tumor (LCCSCT) is a variant of SCT and is seen in PJS. I...

Introduction: Aromatase inhibitors (AIs) are increasingly used in children and adolescents to augment adult height. Given the potential risks of these drugs in women with breast cancer, detailed cardiovascular examinations in adolescents using these treatments are needed to ensure their safety in the pediatric group. The aim of this study was to investigate the effects AIs on cardiac morphology, functions and their relation to several metabolic parameters in a...
