The relationship between LH and thyroid volume in patients with PCOS.

Background: Thyroid volume (TV) has been found to be associated with age, anthropometry, smoking, iodine status and hyperinsulinemia. Hyperinsulinemia is frequent finding in patients with PCOS and has associations with TV. However, the TV has been evaluated only a few studies in patients with PCOS.

Serum S100B protein: a useful marker in obstructive sleep apnea syndrome.

Background And Purpose: We aimed to underline the importance of serum S100B protein as a useful biochemical marker in patients with obstructive sleep apnea syndrome (OSAS).

Material And Methods: Forty-three newly diagnosed patients with OSAS (median apnea-hypopnea index [AHI, events/ hour]: 37.5 [range 11.

Parathyroid adenoma screening efficacies of different imaging tools and factors affecting the success rates.

Purpose: We aimed to compare the efficacy of three different parathyroid adenoma screening tools--high-resolution ultrasonography (USG), technetium Tc 99m-methoxyisobutylisonitrile (MIBI) parathyroid scintigraphy, and magnetic resonance imaging (MRI)--and we evaluated the factors affecting the detection success rates.

Methods: Parathyroid imaging was evaluated by USG, double-phase 99mTc-MIBI parathyroid scintigraphy, and cervical MRI in patients with hyperparathyroidism (n=39).

Results: Among the 39 patients, USG, parathyroid scintigraphy, and MRI correctly identified 35 adenomas (89.

Modulation of the immune response to HBV vaccination by hemodialysis membranes.

Introduction: Seroconversion response to Hepatitis B virus (HBV) vaccination is limited in uremic patients because of impaired humoral and cellular immune activity. Recent studies show that high-flux (HF) hemodialysis (HD) membranes can improve T cell functions and decrease the proinflammatory cytokine activation more effectively than low-flux (LF) membranes. In regard to HF membranes may have immune modulator effects; we compared the antibody responses to hepatitis B vaccination between HF HD and LF HD membranes.
