Background: Subacute thyroiditis (SAT) is a transient inflammatory, probably viral disease of the thyroid gland. It is clinically characterized by pain, fever, increased erythyrocyte sedimentation rate (ESR) or other markers of inflammation, transient thyrotoxicosis, and has a tendency to recur. In most cases, in addition to the clinical features, scintigraphy and ultrasound may support the diagnosis of SAT. However, in the present case, SAT with an atypical thyroid 99m</...

Objective: Thyroid dysfunctions have various effects on glucose and lipid metabolism. Adiponectin (ADP) is an adipokine decreased in obesity and insulin resistance. In this study, we aimed to investigate the role for ADP in thyroid dysfunction related changes in glucose and lipid metabolism.Methods: Newly diagnosed overt hypothyroid (n=20) and thyrotoxic (n=23) adult patients with a body mass index (BMI)<30 kg/m2 were include...

Glucagon-like peptide-1 (GLP-1) is an increatin hormon with various glucoregulatory effects, and exenatide is a GLP-1 receptor agonist used in the management of type 2 diabetes mellitus. C cell hypertrophy was seen in animals treated with GLP-1 receptor agonists, but the effects of GLP-1 agonists on C-cell proliferation or neoplasia in humans have not been documented formerly. The aim of this study was to evaluate the impact of exenatide on structural and functional features o...

Introduction: The aldosterone-to-renin ratio (A/R) is the most frequently used screening test for primary hyperaldosteronism (PH) and a confirmation test is recommended when it is high. We aimed to determine the frequency of PH in patients with high A/R and investigated possible clinical features that might help to prevent unnecesary confirmation tests.Method: Patients who underwent saline infusion test because of high A/R (>3.8) were retrospectively...

Introduction: Subacute thyroiditis is an iflammatory disease of the thyroid gland characterized by pain, tenderness and swelling in the neck. Less frequently, it may present with painless or silent thyroiditis that occurs spontaneously or in the postpartum period. In a few studies in the literature, urinary iodine was reported to be high in patients with postpartum thyroiditis, but it was not evaluated in patients with subacute thyroiditis. We aimed to evaluate urinary iodine ...

Introduction: In our country, some health institutions are allowed to constitute additional service buildings/centers in order to increase the accessibility to outpatient services and decrease the crowdiness in hospitals. We aimed to investigate the satisfaction of the patients evaluated in our endocrinology and metabolism diseases center-ENDOOTEM (Endocrinology-Nuclear Medicine-Diabetes-Obesity-Osteoporosis-Thyroid Diagnosis and TreatmentCenter)- which serves as a part of our...

Objective: To evaluate the relation of mean platelet volume (MPV) levels with serum paraoxonase-1 activity in diabetic patients with respect to obesity and diabetic complications.Methods: A total of 201 diabetic patients grouped with respect to obesity obese (n=89) and non-obese (n=112) and diabetic complications with (n=50) or without (n=150) microvascular complications and with (n=91) or without (n=...

Introduction: High level of Parathormone (PTH) impair bone health by increasing the risk of fracture. The aim is to determine the threshold value of PTH elevation to accompany deficiency or failure of Vit D. This may be an important parameter in assessing bone metabolism in clinical practice.Material and method: 931 patients who were referred to the endocrinology clinic were retrospectively studied and 880 patients diagnosed with Vit D deficiency include...

Aim: Hashimoto’s thyroiditis (HT) is the commonest autoimmune thyroid disease. Papillary thyroid cancer (PTC) is the most often thyroid cancer and its incidence is increasing yearly. It is not clear that HT is a predisposing factor for PTC. We studied PTC’s frequency among HT patients went to total thyroidectomy.Materials and methods: Five hundred and thirty four patients done total thyroidectomy by general surgery were evaluated retrospectivel...

Duplication of the guanine nucleotide-binding protein beta subunit 3 (GNB3) gene is associated with early-onset obesity in individuals with an unbalanced chromosome translocation. Additionally, a cytosine to thymine (C825T) polymorphism in GNB3 is associated with hypertension, obesity and metabolic syndrome; however, the mechanism of GNB3-related obesity is unknown. We created BAC-transgenic mice that carry an extra copy of the human risk-allele (T) ...
