Aim: The primary objective of this study was to evaluate the structural and functional cardiac parameters with MRI in patients with primary hyperparathyroidism (pHPT) before and after successful surgery.Method: In this prospective study 16 patients with pHPT were included. Detailed cardiac magnetic resonance imaging (MRI) examinations were performed preoperatively and at six months post-surgery. Following parameters were measured: Left ventricle ejection...

Introduction: Generously supported by IPSEN)-->Acromegaly increases cancer risk. We aimed to determine the prevalence and the predictors of tumors in acromegalic patients treated at our department.Design: We retrospectively evaluated 142 acromegalic patients (75 females (mean age 52.1±10.4 years and 67 males (mean age 49.4±12.7 years)) treated at university center, endocrinology outpatient clinic betw...

Background: Primary hyperparathyroidism (PHPT) is associated with various musculoskeletal complaints. It is difficult to evaluate muscle strength as it is hard to extract objective data due to lack of definite methods for measurement.Objective: To assess the differences between PHPT patients and healthy controls regarding maximum foot force and plantar pressure distribution by using platform pressure measuring system [Footscan (RSscan)].<p class="abs...

Introduction: 3-Iodothyronamine (T1AM) is a novel endogenous relative of thyroid hormone able to interact with specific G protein-coupled receptors, known as trace amine-associated receptors (TAAR). Metabolic, endocrine and cardiac effects of exogenous T1AM have been reported.Methods: We synthesized radiolabelled T1AM, [125I]-T1AM, and explored its distribution in different mouse organs after injection in the tail vein. The specificity of [<su...

Objective: Different methods are used to identify individuals with insulin resistance. The gold standard is the euglycemic-hyperinsulinemic clamp. However, in clinical practice, clamp is not preferred because it is cumbersome, the HOMA-IR index is used more often. The Trigliserid-glucose (TyG) index is a new and practical way to identify individuals with insulin resistance (IR). When compared to HOMA-IR, this index has been shown to be more reliable in determining insulin resi...

Nivolumab is the first programmed death 1 (PD-1) immune checkpoint inhibitor. It is approved for use in advanced melanoma and squamous non small cell lung cancer (NSCLC). PD-1 immune checkpoint inhibitors can cause autoimmune disease of endocrine glands, including the thyroid. Here, we present a case of thyroiditis after nivolumab therapy.A 61 year-old female patient with NSCLC was consulted to endocrinology department for abnormal thyroid function test ...

Background and aim: Incidentally discovered adrenal masses (adrenal incidentalomas (AI)), generally 1 cm or more in diameter, are mostly benign and asymptomatic and are often considered as nonfunctional tumors. The aim of this study was to perform the imaging characteristics, endocrinologic screening and histologic diagnoses of adrenal incidentaloma cases encountered in our institute.Methods: This retrospective evaluation of patients with AI includes 543...

Objective: Gestational diabetes mellitus (GDM) is the consequence of increased insulin resistance during pregnancy in predisposed individuals who already have impaired insulin secretion due to beta-cell dysfunction as in maturity onset diabetes of young (MODY) cases. Here we aimed to document the association between MODY subtypes and GDM to understand the pathogenesis of GD.Design: Matched, case-control study.Method: Ninety-three p...

Background: Endocrine-related adverse effects of immune check-point inhibitors (ICIs) have been identified in growing number of cancer patients.Case presentation: A 49-year-old male with laryngeal cancer applied to ouroutpatient clinic with weakness, loss of appetite, weight loss, nausea and vomiting for the last three weeks. He was diagnosed with T3N1M0 laryngeal squamous cell cancer seven months before this admission and was given concurrent cisplatin ...

Posaconazole is a member of triazole antifungal family. It is frequently used prophylaxis and treatment in invasive fungal infections. Among the azole group antifungals, ketoconazole is well known to affect steroidogenesis through cytochrome P450 enzymes, however, posaconazole-induced adrenal insufficiency has been reported in only two cases in the literature. Here, we present our case of adrenal insufficiency induced by posaconazole.A 54-year-old male a...
