Signal peptide-CUB-EGF domain-containing protein 1 (SCUBE1) levels in patients with overt and subclinical hyperthyroidism: effects of treatment.

Background And Objectives: Signal peptide-CUB-EGF domain-containing protein 1 (SCUBE1) has been shown to increase in parallel with platelet activation in acute ischaemic and thrombotic diseases. There has been no study evaluating SCUBE1 levels in patients with overt hyperthyroidism (OHyper) and subclinical hyperthyroidism (SHyper), conditions which are known to show impairment of both endothelial and platelet function. This study sought to evaluate SCUBE1 concentrations in patients with SHyper and OHyper, and assessed the effects of antithyroid drug (ATD) therapy on circulating SCUBE1 levels.

Prevalence of gestational diabetes mellitus and associated risk factors in Turkish women: the Trabzon GDM Study.

Introduction: The aim of this study was to investigate the prevalence of gestational diabetes mellitus (GDM) in Turkish pregnant women in the Trabzon Region and further to identify population-specific risk factors for GDM.

Update on idiopathic hirsutism: diagnosis and treatment.

Idiopathic hirsutism (IH) is defined as hirsutism in conjunction with normal ovulatory function and normal serum androgen levels. The pathogenesis of IH is still not clear. Increased peripheral 5alpha-reductase enzyme activity and abnormalities of androgen receptor gene polymorphisms have been postulated to explain the pathogenesis of this disorder.

Current prevalence of goiter determined by ultrasonography and associated risk factors in a formerly iodine-deficient area of Turkey.

The aim of this study was to determine the prevalence of goiter and related risk factors in an adult population in a formerly iodine-deficient area of Turkey. In this cross-sectional study, we enrolled 2,500 subjects (1,270 women and 1,230 men, aged over 20 years) by multistage sampling. Blood and urine specimens were collected for the assessment of thyroid function.

Investigation of serum bisphenol A, vitamin D, and parathyroid hormone levels in patients with obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS) is a common health problem, and associated with obesity, metabolic syndrome (MetS), and diabetes. Growing evidence shows that 25-hydroxyvitamin-D3 (25-OH-D) insufficiency and high parathyroid hormone (PTH) levels may be correlated to glucose intolerance, MetS, obesity, and cardiovascular abnormalities similar to OSAS. Bisphenol A (BPA) is an endocrine disruptor agent which exerts a wide variety of metabolic effects.

BACKGROUND. Ganglioneuromas (GNs) are neural crest cell-derived tumors and rarely occur in the adrenal gland. They are usually asymptomatic and hormonally silent.

Left ventricular synchronicity is impaired in patients with active acromegaly.

Acromegaly is associated with a variety of cardiovascular disturbances such as left ventricular hypertrophy, diastolic cardiac dysfunction, and hypertension. Left ventricular (LV) dyssynchrony means the impairment of synchronicity and is defined as the loss of the simultaneous peak contraction of corresponding cardiac segments. The objective of this study was to investigate whether acromegalic patients have left ventricular dyssynchrony.

The assessment of left ventricular systolic asynchrony in patients with primary hyperparathyroidism.

Objectives: Primary hyperparathyroidism (PHP) is associated with a variety of cardiovascular disturbances such as left ventricular (LV) hypertrophy, diastolic cardiac dysfunction, and hypertension. LV asynchrony is defined as the loss of the simultaneous peak contraction of corresponding cardiac segments. The objective of this study was to assess systolic asynchrony in patients with overt hyperparthyroidism.

Thyroid disorders and hypercoagulability.

Various abnormalities of coagulation and fibrinolysis, ranging from subclinical laboratory abnormalities to clinically significant disorders of hemostasis, but rarely major hemorrhage or thromboembolism, may occur in patients with thyroid diseases. This review discusses the relationships between thyroid dysfunction and the coagulation/fibrinolytic system. According to the recent literature, most of the coagulation/fibrinolytic abnormalities associated with thyroid dysfunction are the consequences of direct effects of thyroid hormones on the synthesis of various hemostatic parameters.

Intra-left ventricular systolic asynchrony in patients with overt hyperthyroidism.

Hyperthyroidism causes a variety of adverse effects on the cardiovascular system. Left ventricular (LV) asynchrony is defined as loss of the simultaneous peak contraction of corresponding cardiac segments. The aim of this study was to assess systolic asynchrony in patients with overt hyperthyroidism.

Blood coagulation, fibrinolysis and lipid profile in patients with prolactinoma.

Objective: Although the strong association between hyperprolactinaemia and platelet aggregation is well recognized, there are no studies on changes in coagulation and fibrinolytic status in patients with prolactinoma. To our knowledge, tissue plasminogen activator inhibitor-1 (PAI-1), plasma tissue factor pathway inhibitor (TFPI) and thrombin-activatable fibrinolysis inhibitor (TAFI) levels in these patients have not been investigated. Therefore, the main purpose of this study was to evaluate the markers of endogenous coagulation/fibrinolysis, including TFPI and TAFI, and to investigate the relationships between prolactin (PRL) and these haemostatic parameters and serum lipid profile in patients with prolactinoma.

Increased thrombin-activatable fibrinolysis inhibitor and decreased tissue factor pathway inhibitor in patients with hyperthyroidism.

Various abnormalities of coagulation-fibrinolytic system have been reported in patients with thyroid dysfunction. Several studies indicate that coagulation and fibrinolytic system is disturbed in the patients with hyperthyroidism. The levels of plasma thrombin-activatable fibrinolysis inhibitor (TAFI) antigen and tissue factor pathway inhibitor (TFPI) have been very rarely investigated in patients with hyperthyroidism.

Primary thyroid paraganglioma presenting with double thyroid nodule: a case report.

Paragangliomas (PGs) are exceptionally rare tumors. Only 24 cases have previously been reported. Both preoperative and postoperative differential diagnosis is very difficult.

A novel indicator of widespread endothelial damage and ischemia in diabetic patients: ischemia-modified albumin.

Ischemia-modified albumin (IMA) is a novel marker of tissue ischemia. Nowadays, IMA is accepted as a marker of oxidative stress. In this study, we aimed at establishing an association between IMA and hyperglycemia, blood pressure, lipid parameters, microvascular complications, hsCRP, and microalbuminuria in type 2 diabetes patients without overt macrovascular disease and acute ischemia.
