Aim: Hashimoto’s thyroiditis (HT) is an autoimmune disease in which a breakdown of immune tolerance is caused by interplay of a variety of immunologic, genetic, and environmental factors. Mean platelet volume (MPV) is the measure of platelet size. MPV possibly is a simple way to estimate platelet activity. Activated platelets play an important role in the pathogenesis of vascular disease especially coronary heart diseases. Larger platelets are metabolically and enzymatica...

Introduction and objective: Platelets play an important role in the development of thrombotic events. Increase of mean platelet volume (MPV) may indicate pre-thrombotic conditions as a new cardiovascular marker. Larger platelets have been reported to be metabolically more active than smaller ones. Our aim of present study is to evaluate MPV levels in patients with papillary thyroid cancer.Materials and methods: Forty-seven patients with newly diagnosis m...

Background and aim: C-reactive protein (CRP) is a sensitive marker for systemic inflammation. In this study we aimed to investigate the relationship between high-sensitivity C-reactive protein (hs-CRP) levels and BMI, body fat mass and fat distribution in healthy subjects.Subjects and methods: A total 117 healthy subjects aged with 20–68 yr [normal weight (BMI 18.5–25.0 kg/m2, n:35), overweight (BMI: 25–30 kg/m2</sup...

Background and aim: Carotid intima-media thickness (IMT), as assessed by B-mode ultrasound, is a commonly used clinical marker that reflects systemic burden of atherosclerosis and value of IMT at or above 1 mm at any age is associated with a significantly increased risk of myocardial infarction. On the basis of such findings, we aimed to clarify the relationship between carotid intima-media thickness and anthropometric and metabolic parameters in virtually healthy subjects.</p...

Background and aim: It was known that NT-proBNP levels increased in cardiac failure. But, NT-proBNP levels in different thyroid status still unclear. We aimed to evaluate serum NT-proBNP levels in both of hyperthyroid and hypothyroid patients without cardiac insufficiency.Subjects and methods: Thirty nine patients with hyperthyroidism (43.0±16.5 yr), 25 patients with hypothyroidism (35.4±13.9 yr) and 34 ages matched euthyroid subjects (41.4&#17...

Background and aim: Somatostatin analogues such as octreotide acetate were used in acromegalic patients as primary or secondary treatment. In this study we aimed to report completely disappearing of adenoma and clinical cure in 3 acromegalic cases that rejected surgical treatment.Case1: E.A (62 years old, female) She reported enlargement of his hands, deepening of his voice and increases in shoe size. MRI revealed a macro adenoma which was spread to cave...

Background and aim: Hyperprolactinemia may associate with insulin resistance. This fact has been determined by many studies with methods which show insulin sensitivity. In this study we aimed to search insulin resistance with golden standard euglycemic hyperinsulinemic clamp technique on hyperprolactinemic patients.Subjects and methods: This study was performed in Endocrinology Department of Dicle University. Sixteen patients with microprolactinoma (mean...

Diabetes mellitus (DM) includes a group of carbohydrate metabolism disorders that is characterized by hyperglycemia and leads long-term macro- and microvascular complications. Also siblings of type 2 diabetic patients have increased relative risk of micro and macrovasculer outcome of DM even though their plasma glucose levels in normal range. Genetically determined hyperinsulinemia, insulin resistance and associated dyslipidemia have crucial role in the processes of vascular a...

Hyperinsulinism has been shown to trigger sympathetic activity experimentally, however the clinical and epidemiologic data on the association of heart rate with hyperinsulinism and insulin resistance. This study was investigated the relationship between insulin resistance and exercise test parameters in unselected consecutive middle aged asymptomatic patients with type II diabetes.Ninety asymptomatic type II diabetics between the ages 36 and 60 without a...

Background: Phthalates are currently used in medical devices, adhesives as plasticizers. Masculine reproductive toxicity is the greatest concern associated with exposure, known as the “phthalate syndrome”. The European Chemicals Agency has recognized di-butyl-phthalate (DBP, CAS 84-74-2) as an endocrine disruptor with deleterious effects on reproductive hormones, with an estimated human intake of 0.84-5.22 μg/kg/day. Effects reported include the disruption of Se...
