Predictive factors for success of radioactive iodine treatment in graves’ disease

Quitalo Ana , Henriques Francisca , Franco Sara , Barbosa David , Manuel Costa Maria , Carlos Cordeiro Maria , Raimundo Luisa

Objectives: Correction of 131I dose for thyroid gland size is one of the methods used to determine radioactive iodine (RAI) activity for patients with Graves’ disease (GD), but the predictive factors for its clinical outcome are still unclear. This study aimed to investigate which factors influence its success in a real-world cohort.Methods: Observational and retrospective study of RAI treatments in a terciary referral center in Almada, Portugal, ca...

Efficacy of radioactive iodine treatment in graves’ disease using a calculated 131i dose in a portuguese cohort

Henriques Francisca , Quitalo Ana , Franco Sara , Barbosa David , Manuel Costa Maria , Carlos Cordeiro Maria , Raimundo Luisa

Objective: To evaluate the success of administration of 131Iodine adjusted for thyroid gland size in the treatment of hyperthyroidism in Graves’ disease.Methods: All patients with Gravés hyperthyroidism who underwent therapeutic administration of 131I in a referral center in Portugal, from 2014 to 2022 were selected. Values of estimated thyroid gland size, administrated doses of 131I and 24h radioactive iodine u...

Efficacy of intrathyroidal dexamethasone injection in steroid-dependent subacute thyroiditis – preliminary report of dlisat study

Stasiak Magdalena , Rosińska Magdalena , Berkan-Dudzińska Zuzanna , Zygmunt Arkadiusz , Lewinski Andrzej

Objectives: Steroid-dependent subacute thyroiditis (SAT) is a challenging clinical problem. Long-term treatment and high cumulative doses of systemic steroids are associated with high risk of steroid-related complications. The DLISAT study aims to evaluate the efficacy and safety od intrathyroidal dexamethasone injections in chosen groups of patients, comparing the outcomes with standard oral steroid therapy. This paper presents the preliminary results focusing on two patients...

J-131 therapy in patients with autonomously functioning thyroid nodules and normal FT4 blood level

Lacic Miodrag

Objective: The purpose of this study was to evaluate the results of radionuclide therapy with iodine-131 (I-131) in patients (pts) with autonomously functioning thyroid nodules (AFTNs) and a normal thyroid hormone (FT4) blood level.Methods: In this study 131 cytological benign AFTNs in 116 pts (100 female and 16 male) with normal FT4 level have been treated with a fixed I-131 doses (370 MBq). Clinical exam, ultrasonography with color Doppler (US), fine n...

Proficiency in performing radiofrequency ablation procedure for non-functioning benign thyroid nodules: a qualitative rather than quantitative matter

Chytiris Spyridon , Teliti Marsida , Croce Laura , Coperchini Francesca , Grillini Beatrice , Cerutti Matteo , Fonte Rodolfo , Magri Flavia , Rotondi Mario

Objective: Radiofrequency ablation (RFA) is an emerging non-surgical treatment for benign thyroid nodules (BTN). Despite its proven safety profile, data on the learning curve (LC) required to achieve proficiency are still lacking.Materials and methods: The first 179 RFA procedures performed by a single operator in patients with non-functioning BTN were retrospectively analyzed. Six-month nodule volume reduction rate (VRR) ≥ 50% was regarded as refl...

Laser thermal ablation for benign thyroid nodules: a single polish centre experience

Domagała Bartosz , Kamińska Magdalena , Kieć-Klimczak Małgorzata , Motyka Marcin , Sokołowski Grzegorz , Trofimiuk-Muldner Malgorzata , Hubalewska-Dydejczyk Alicja

Introduction: Percutaneous laser thermal ablation is a minimally invasive method of shrinking benign thyroid tumors (also used in selected cases of papillary thyroid cancer or primary hyperparathyroidism). Pressure symptoms and a cosmetic defect are main indications for this procedure.Aim: The aim of the study was to present the results of percutaneous laser thermal ablation for benign thyroid nodules performed in a single Polish center.<p class="abs...

Safety and efficacy of ultrasound-guided thrombin injection for pseudoaneurysms arising after ultrasound-guided biopsy of thyroid nodules

Ham Taehyuk , Ye Lee Ji , Kim Ji-Hoon , Jeon Younghoon , Sung Choi Kyu

Purpose: Iatrogenic pseudoaneurysm is a rare but potentially fatal complication of thyroid biopsy. However, the standard management strategy for thyroid pseudoaneurysm is not established. In this study, we aimed to evaluate the incidence, imaging features, clinical manifestations of pseudoaneurysms occurring after thyroid biopsy and to evaluate the efficacy and safety of US-guided percutaneous thrombin injection for pseudoaneurysm.Materials and Results: ...

Prevalence and ultrasonography features of thyroglossal duct cyst in adults according to radioactive iodine ablation

Lee Yoojin

Objectives: This study aimed to assess the prevalence and US features of TGDCs in adults on ultrasonography (US), and to assess whether the prevalence or size of TGDCs increases after RIA.Methods: A total of 2820 patients underwent thyroid or neck US examination between July and December 2018. Among them, 54 patients were excluded owing to young age (<19 years; n = 52) and a history of radiation ther¬apy to the neck (n = 2). Ev...
