Thyroid cancers are divided into two main subgroups according to their embryonic origin: papillary cancer, the most common histologic type, seen in 75–80%, and medullary cancer, seen in 5–10% (sporadic or as a component of multiple endocrine syndrome). Because of the different phenotypic characteristics of these two cancers, it’s unusual for them to present simultaneously. Since 1980, only a few cases of simultaneous papillary and medullary thyroid cancer have b...

Vitamin D role is not only associated with mineral metabolism and bone health but also in globally important diseases such as obesity and metabolic syndrome. The aims of this study were to investigate: i) 25(OH) vitamin D levels in obese patients with and without metabolic syndrome and compare these with levels in healthy subjects, ii) the relationship between serum 25(OH) vitamin D levels and metabolic syndrome components such as body mass index, waist circumference, blood pr...

Introduction and Aim: In our study, the frequency of exocrine pancreatic insufficiency, and its relationship with the duration of diabetes and the level of glycemic control and other complications of diabetes were investigated in patients with diabetes mellitus.Materials and Methods: This paper was supported by Manisa Celal Bayar University Scientific Research Projects Coordination Unit, Project Number 2021-086. A total of 249 diabetic patients, 21 with ...

Introduction: Because of their anti-inflammatory effect, topical corticosteroids are widely used in dermatological diseases. Topical use is typically safe, but serious adverse effects induced by systemic absorption are occasionally reported. We report a patient who developed Cushing’s syndrome due to long-term misuse of topical bethametasone and clobetasol.Case Report: A 24-year-old man presented with rapid weight gain and purple strias in multiple ...

Introduction: Impaired fasting glucose (IFG) is defined as being present in those whose fasting blood glucose level is consistently elevated above normal, but is not high enough to be considered as having diabetes mellitus. Impaired glucose tolerance (IGT) is defined as being present in those whose second hour plasma glucose level is higher than normal, but is not high enough to be considered as having diabetes mellitus. Low serum 25-hydroxyvitamin D levels are associated with...

Introduction: Thyroid hormones play an important role in achieving and maintaining reproductive functions. Thyroid dysfunction affects the menstrual cycle and often leads to menstrual irregularity. We prospectively investigated untreated female patients presenting to our Endocrinology and Internal Medicine outpatient clinics.Material and methods: All the patients were of reproductive age and were newly diagnosed with thyroid dysfunction. After a detailed...

Rhabdomyolysis is a characterized by muscle necrosis and release of intracellular muscle constituents into the circulation. Most cases are associated with a predisposing factor such as high dose statin therapy, diabetes, old age, female gender, renal failure or hypothyroidism.An 80-year-old woman presented with severe and generalized muscle pain. Her medical history included hypertension, congestive heart failure, chronic atrial fibrillation and a thy...

Vitamin D is a lipid-soluble hormone found in certain foods and synthesized from precursors in the skin when exposed to ultraviolet light. Vitamin D plays a critical role in bone metabolism and many cellular and immunological processes; and low levels have been associated with several chronic and infectious diseases. Vitamin D status is assessed by measuring the concentration of serum 25-hydroxy vitamin D (25(OH) D). Vitamin D deficiency is reported to be common worldwide, but...

Osteoprotogerin (OPG) and the receptor activators of nuclear factor-kβ (RANK) and nuclear factor-kβ ligand (RANKL) play an important role in bone metabolism. RANKL binds to RANK, which is expressed by osteoclasts, whereas OPG acts as its decoy receptor, blocking the RANK–RANKL interaction.The aim of our study was to evaluate bone turnover parameters (serum calcium, phosphorus, alkaline phosphatase, parathormone, osteocalcine, 24-...

Background: Hashimoto’s thyroiditis is a chronic autoimmune thyroiditis. It is the most common cause of primary hypothyroidism in adolescent period, via autoimmune thyroid tissue destruction and affecting 2% of the population. In this study we want to investigate the role of the cytokines such as IL-2, IL-12, TNF-α and IFN-γ in the pathogenesis of the disease and the changes of cytokine levels with the L-thyroxine treatment....
