Background: There is some evidence suggesting an interaction between renin-angiotensin-aldosterone system and parathyroid hormone (PTH). Decreased aldosterone levels after parathyroidectomy have been reported in patients with primary hyperparathyroidism (PHPT). Recently, most of the diagnosed patients with PHPT are mild or asymptomatic. Our aim was to investigate plasma aldosterone and renin concentrations in patients with asymptomatic PHPT.Methods: Thir...

Thyroid lymphomas are very rare diseases of the thyroid.We present three patients with thyroid lymphoma administered our department last year. Two of the patients presented with rapidly enlarging neck mass with pressure symptoms, and the other was diagnosed during the evaluation of a thyroid nodule. Two patients had the Hashimoto’s thyroiditis diagnosis. All the patients underwent surgery, since no exact diagnosis could be established with fine feed...

Dipeptidyl peptidase 4 (DPP-4) is thought to play a role in the pathophysiology of metabolic and inflammatory diseases. Increased ADA activity has been suggested to induce insulin resistance and inflammation. We investigated DPP-4 and ADA activities, serum nitric oxide (NO) level and nitric oxide synthase (NOS) activity which are the oxidative stress parameters in patients with PCOS. Fifty two women with PCOS and 41 healthy women were included in this study. Serum ADA activity...
