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: 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...

Objective: Vitamin D is an immune-modulator that may play a role in thyroid related autoimmunity. But the relation between Vitamin D and Graves’ disease (GD) is not well defined yet. The aim of this study was to investigate the association of 25-hydroxy-vitamin D (25[OH]D) levels and TSH receptor antibody (TRab) levels in GD.Design: A total of 429 GD patients were analyzed retrospectively. 122 of 429 patients had vitamin D levels were enrolled in th...

Langerhans cell histiocytosis (LCH) is a disease with monoclonal proliferation and infiltration of organs by Langerhans cell. LCH is commonly seen in the skeletal system and skin, but it may also involve paranchymal organs. Thyroid involvement in LCH is unusual, and coexistence of thyroid with lung involvement is seen very rare. Here we present a patient with LCH, who has thyroid and lung involvement.Case: A 26-old woman, who had LCH of the lung was refe...

Introduction: Hyperthyroidism is the condition that occurs due to excessive release of thyroid hormone by the thyroid gland. Anti-thyroid drugs are usually the first choice of the treatment but surgery and radioactive iodine can also be used in treatment of hyperthyroidism. Plasmapheresis is a rapid and effective treatment option in cases where immediate euthyroidism is needed to be obtained due to complications of thyrotoxicosis and major side effects of antithyroid drugs.</p...

Aim: To compare macular pigment optical density (MPOD) in diabetic and non-diabetic patients by using heterochromatic flicker photometry and to investigate the correlation of MPOD with glycosylated hemoglobin (HbA1C), serum lipid levels and vitamin D levels.Methods: Sixty-seven patients with 10/0 visual acuity were divided into group 1 (controls, n: 35) and group 2 (diabetics without retinopathy, n: 32). MPOD was measured with a heteroc...

Objective: Radioiodine (RAI), surgical and anti-thyroid drug therapy are the main options to treat Graves’ disease (GD). The aim of this study was to investigate theurapeutic options, their efficacy and adverse reactions of prophilthiouracil (PTU) and methimazole (MMI).Design: A total of 650 patients with GD were evaluated retrospectively. Treatments, adverse reactions, clinical and laboratory results were recorded. After 18 months of primary medica...

Aim: The aim of the present study was to evaluate the characteristic features of computerized tomography (CT) and magnetic resonance imaging (MRI) among functioning and non-functioning adrenal lesions.Materials and methods: We retrospectively reviewed the medical records of patients with adrenal mass. CT or MRI findings were available in 89 functioning and 148 non-functioning adrenal lesions (NFAL). Of the patients with functioning adrenal mass, 34 were ...
