Urinary neopterin levels in patients with thyroid cancer.

Increased urinary neopterin concentrations have been described in many cancers. We aimed to evaluate the urinary neopterin levels in thyroid cancer. Sixty-nine patients with thyroid cancer, 76 patients with benign thyroid pathology and 33 healthy subjects were evaluated.

"Is there any association between insulin resistance and thyroid cancer? : A case control study".

Insulin stimulates proliferation of thyroid cells in culture. The presence of insulin resistance (IR) is associated with larger thyroid gland volume and an increased prevalence of thyroid nodules. The aim of this study was to investigate the presence of any possible association between IR and thyroid cancer.

Effect of cabergoline on insulin sensitivity, inflammation, and carotid intima media thickness in patients with prolactinoma.

The aim of this study was to evaluate the effect of Cabergoline on insulin sensitivity, inflammatory markers, and carotid intima media thickness in prolactinoma patients. Twenty-one female, newly diagnosed patients with prolactinoma were included in the study. None of the patients were treated previously.

The relationship between aortic stiffness and left ventricular function in patients with Cushing's disease: aortic stiffness in Cushing's disease.

We aimed to investigate the aortic function and to evaluate the relationship between aortic stiffness and systolic and diastolic functions of the left ventricle in patients with Cushing's disease (CD). Fourteen women and one man with newly diagnosed CD, and 17 control cases were enrolled in this study. All subjects underwent echocardiography and systolic and diastolic aortic measurements were noted from M-mode aortic root.

Coexistent familial nonmultiple endocrine neoplasia medullary thyroid carcinoma and papillary thyroid carcinoma associated with RET polymorphism.

Familial nonmultiple endocrine neoplasia medullary thyroid cancer accounts for 10% to 15% of hereditary medullary thyroid carcinoma and is characterized by lack of accompanying endocrine or nonendocrine diseases. Simultaneous occurrence of medullary and papillary thyroid carcinoma in the same patient is rare and known as collision tumor. Here, the authors present familial nonmultiple endocrine neoplasia medullary thyroid cancer in 4 sisters, all having RET proto-oncogene polymorphism in exon 15 at codon 904 and 2 having additional polymorphism in exon 13 at codon 769.
