Investigating the value of fine needle aspiration cytology in thyroid cancer.

Background: Current guidance recommends the use of fine needle aspiration cytology (FNAC) as an essential investigation in patients presenting with a thyroid lump. Current literature suggests that the sensitivity of FNAC in thyroid nodules ranges between 80-90%. However, only very few studies have looked specifically at the sensitivity of FNAC in solely thyroid cancer patients.

Efficacy of perioperative thromboprophylactic agents in the maintenance of anastamotic patency and survival of rat microvascular free groin flaps.

Objectives: We sought to determine the thromboprophylactic effects of low-molecular-weight heparin (LMWH) and pentoxifylline.

Design: Randomized blinded study. Materials and methods Sixty Sprague-Dawley rats were assigned to 1 of 4 treatment groups: (1) control group (n = 15), (2) pentoxifylline group (n = 15), (3) LMWH group (n = 15), and (4) combined therapy group (n = 15).
