We consider UGFNAB to be superior to PGFNAB for obtaining adequate material especially for small-sized nodules, as well as providing more accurate cytologic evaluation. Indeed, the difference between the costs of two procedures might be acceptable.

Serum RBP4 is not a predictive factor in NAFLD irrespective of ALT. Low adiponectin, elevated resistin, and leptin were significantly associated with necroinflammation.

Our results suggest that the early administration of NAC may have a protective effect in the rat experimental testicular T/D models.

IntroductionLevothyroxine (LT4) therapy has been used for the treatment of euthyroid nodular goiter, but there are controversial results about its usefulness. We aimed to evaluate the possible role of benign nodules’ cytological characteristics in response to LT4 therapy.Material and methodsIn total, 93 patients with 128 nodules were included in the study; 74 of the nodules were treated with LT4 (group 1), and 54 of them had no medication (group 2). The subgroups consisted of adenomatous nodules, colloid nodules and cystic nodules.ResultsIn group 1, mean thyroid volume and mean nodule volume were reduced significantly (p = 0.002 and p = 0.022, respectively) with low-normal level thyrotropin (TSH) suppression (between 0.3 mIU/ml and 1.0 mIU/ml), while there were no significant changes in group 2. When we evaluated changes of the initial and last nodule volumes in cytological subgroups, only colloid nodules in group 1 had significant reduction (p = 0.040) and the others had no significant changes. By omitting the colloid nodules, when the other nodules were revaluated, there were no significant changes in either group.ConclusionsOn the basis of these results, obtained from a large sample of Anatolian patients, it is possible that LT4 therapy leads to significant reductions of both thyroid volume and nodule size in colloid nodules, but not in other kinds of benign nodules.
