Women with positive thyroid autoimmunity are considered at risk of developing hypothyroidism in pregnancy, so monitoring thyroid function is recommended.Objective: To assess the risk of gestational hypothyroidism in pregnant women with autoimmune thyroid disease and normal thyrotropin (TSH) at the beginning of pregnancy.Methods: Retrospective review of data from pregnant women attended between April 2016 and October 2019. Women wit...

Objectives: We studied whether the postoperative serum thyroglobulin (TG) basal levels before treatment with I131 (baseline TG) could be related with the response to treatment. We consider the excellent response as the absence of clinical, biochemical disease (undetectable TG and anti-thyroglobulin antibodies AcTG negative) and/or structural disease.Material and Methods: This is an observational study that includes 100 patients with differentiated thyroi...

Objective: To understand the factors associated with changes in thyroid nodule volume with previous benign citology.Material and Methods: This is a prospective single-center observational study. We included patients with a benign citology from March/2016 to May/2018 and ultrasound follow-up after 12–24 months. Initially we determined the nodule size (volume in ml), and its risk of malignancy was classified according to ATA 2015 criteria. Volume cha...

Objective: Incidentally discovered thyroid microcarcinomas (TMc) are tumors with a maximal diameter ≥1 cm, indetified during a detailed histopathology examination following a thyroidectomy performed for reasons not pertaining to malignancies of the thyroid gland.Methods: We included 1555 patients who underwent a total thyroidectomy for benign disease between January 2005 and December 2018. Patients with post-surgical pathology consistent with thyro...

Introduction: Hypothyroidism during pregnancy has been asociated with adverse maternal and neonatal outcomes. During pregnancy, maternal levothyroxine (LT4) dose requirements increase. The aim of this study is to determine the increase of LT4 doses during pregnancy in pregestational hypothyroid women.Methods: We included 76 hypothyroid pregnant women. We analyzed analytical and clinical characteristics of these patients, as well as the increase of LT4 re...
