Toxic nodular goiter

PURPOSE: This article aims to describe the presentation of Plummer disease and its evolution after radioiodine treatment and determine factors that may influence treatment efficacy. PATIENTS AND METHODS: The sample included retrospective medical records of 165 adult patients with toxic nodular goiter treated with radioiodine between 1997 and 2017, followed up at a single thyroid center. RESULTS: The efficacy of treatment with a single dose of radioiodine was higher than 90%...

BACKGROUND: Dermatomyositis is an inflammatory myopathies causing proximal muscle weakness accompanied by muscular inflammation and skin rash. Dermatomyositis patients have a higher incidence of malignancy as compared to the general population. CASE REPORT: A 52-year-old known female patient with a toxic multi-nodular goiter presented with insidious onset of itchy erythematous rash on her neck and bilateral hands and progressive muscle weakness of 4 months' duration...

BACKGROUND: The frequency of thyrotoxicosis may vary between countries and some laboratory test results may be used in etiology research. This study aimed to evaluate the prevalence of thyrotoxicosis diagnoses and laboratory test results. METHODS: 3246 patients with overt thyrotoxicosis were included in this study. Laboratory test results, epicrisis, thyroid ultrasonography, thyroid scintigraphy, and radioactive iodine uptake test reports of the patients were examined in the study...

BACKGROUND: Subclinical thyrotoxicosis (SCH) is characterized by normal serum thyroid hormone levels and low thyrotropin levels. The impact of this condition on the skeletal system may vary depending on its cause, yet the relationship is not fully comprehended in premenopausal women. Studies are scarce about its effects on bone health in our population. OBJECTIVES: This study aims to evaluate the bone mineral density (BMD) and bone turnover markers in premenopausal women with SCH and determine if any differences exist based on the condition's etiology...

OBJECTIVES: Cancer is the second most common cause of death worldwide. It is currently debated whether thyroid dysfunction is a modifiable cancer risk factor. Our aim was to evaluate the risk of cancer in patients with hyperthyroidism. METHODS: This is a register-based nationwide cohort study of individuals with a diagnosis of hyperthyroidism. Each hyperthyroid case was matched with four reference individuals according to age and sex. Using Fine and Gray competing risk regression models, we studied the association of hyperthyroidism and subsequent all-cause cancer diagnoses, adjusted for preexisting morbidity...

OBJECTIVE: To assess the bedside utility of spectral Doppler ultrasound (SDUS) in the initial evaluation of patients presenting with thyrotoxicosis. METHODS: This is a retrospective cross-sectional study of patients diagnosed with thyrotoxicosis at an academic outpatient endocrinology clinic from August 2019 to November 2022. The thyroid arteries' peak systolic velocities (PSV) were measured bilaterally using SDUS. PSV ≥40 cm/sec in at least a single thyroid artery was considered a reasonable cut-off for Graves' disease, and PSV of peri-nodular artery ≥ 25 cm/sec for toxic adenoma...

INTRODUCTION: Nontoxic nodular goiter is one of the most prevalent thyroid conditions worldwide. Thyroidectomy for large goiters has a relatively high risk of postoperative airway obstruction, with tracheomalacia being one of the potential complications. CASE REPORT: A 61-year-old woman complained of a lump in her neck for 45 years. The node is progressively enlarged, but she did not experience any breathing difficulty, hoarseness, or pain while swallowing...

BACKGROUND: Agranulocytosis is a rare but fatal side effect of antithyroid drugs (ATDs) with incidence reported at 0.1%-1%. Agranulocytosis is defined as a granulocyte count <500 cells/μL following the use of ATDs and is an absolute contraindication to the use of these drugs; in this case, radioactive iodine (RAI) or surgery are therapeutic options. CASE PRESENTATION: A 28-year-old female patient was on follow-up at our clinic after she presented with anterior neck swelling of 4 years...

Acromegaly is a rare disease, usually caused by a pituitary tumor. It typically exhibits slow evolution and can result in numerous complications. In the present case report, the patient presented with hyperthyroidism associated with ophthalmopathy and right nodular goiter. The laboratory tests revealed persistent high levels of phosphorus without an apparent cause. After ruling out common pathologies associated with this finding, a focus was placed on the clinical aspects associated with acromegaly, a rare cause of hyperphosphatemia...

Background: The main postoperative complications of thyroidectomy are hypoparathyroidism and recurrent laryngeal nerve (RLN) palsy. Methylene blue, which is a drug and dye, is safe and easy to get, and we can use it to avoid complications during thyroidectomy. Objectives: We aim to assess that we can spray Methylene blue to allow the identification of important structures intraoperative which are the parathyroid gland and recurrent laryngeal nerve. Also, to evaluate that this technique is safe, effective, technically feasible, and less dangerous than other techniques...

INTRODUCTION: Thyroid surgery has increased in the pediatric population. One of the main issues following this surgery is the presence of a neck scar, which has been reported to have an impact on quality of life. Transoral endoscopic thyroidectomy is used in adult patients with good results, but there are few reports on the use of this technique in pediatrics. CLINICAL CASE: 17-year-old female patient diagnosed with toxic nodular goiter. As a result of the patient's refusal to undergo conventional surgery due to the scar, transoral endoscopic lobectomy was carried out...

This document provides the new EANM guideline on radioiodine therapy of benign thyroid disease. Its aim is to guide nuclear medicine physicians, endocrinologists, and practitioners in the selection of patients for radioiodine therapy. Its recommendations on patients' preparation, empiric and dosimetric therapeutic approaches, applied radioiodine activity, radiation protection requirements, and patients follow-up after administration of radioiodine therapy are extensively discussed.

Objective  The objective of this study was to assess our local experience with 99m Technitium thyroid uptake (TcTU) in thyrotoxicosis by examining mean and range of TcTU in both euthyroid patients and thyrotoxic patients. We also wanted to see how well TcTU performed as a substitute for radioiodine thyroid uptake in thyrotoxicosis. Methods  The medical records of thyrotoxic patients were reviewed retrospectively. Inclusion criteria were: (1) thyrotoxicosis was proven biochemically, (2) the patient underwent TcTU at the time of thyrotoxicosis diagnosis, (3) at least 6 months of follow-up, and (4) the final diagnosis was documented...

PURPOSE: Autonomously functioning thyroid nodules (AFTNs) are treated with iodine-131 (I-131) therapy, which increases the risk of permanent hypothyroidism; however, the risk can be reduced by separately estimating the accumulated activity for the AFTN and extranodular thyroid tissue (ETT). METHODS: A quantitative I-123 single-photon emission computed tomography (SPECT)/CT (5 mCi) was performed in one patient with unilateral AFTN and T3 thyrotoxicosis. The I-123 concentrations measured at 24 h were 12...

The authors describe thyroidectomy in a patient with multinodular toxic goiter stage V, severe thyrotoxicosis complicated by thyro-cardiac disease, strangulation syndrome and severe comorbidities. Nodular euthyroid goiter was first diagnosed in 1992, and resection of the right thyroid lobe was performed. Progressive enlargement of thyroid gland and thyrotoxicosis occurred after coronavirus infection in February, 2020. Along with progression of thyrotoxicosis and strangulation of cervical organs, the patient suffered from portal vein thrombosis, pulmonary embolism...

OBJECTIVE: This study aimed to evaluate the differences between the types of thyroidectomy surgeries and surgical treatment approaches according to thyroid pathology results, in Turkiye's two non-endemic regions. METHODS: Two different centers of the country, which differ in many respects and are non-endemic for thyroidal diseases were included in the study. Data on patients from both sexes, who underwent thyroidectomy in the western (1st center) and the eastern (2nd center) regions between 2011 and 2017 have been reviewed...

OBJECTIVE: A relationship between thyroid and non-organ-specific autoimmunity could be relevant for Graves' orbitopathy (GO), which affects connective tissue. We investigated the association between GO and anti-nuclear antibodies (ANAs). METHODS: Retrospective investigation was conducted in 265 patients with Graves' disease (GD), 158 with and 107 without GO. Primary outcome was: prevalence of ANAs in GO vs no-GO. Secondary outcomes were: (1) relationship between ANAs and GO features; (2) prevalence of ANAs in GD compared with non-autoimmune hyperthyroidism [(78 patients with toxic nodular goiter (TNG)]; (3) distribution of ANA patterns...

BACKGROUND: The coexistence of primary hyperparathyroidism (PHPT) and giant toxic nodular goiter is very rare. Moreover, PHPT could be easily overlooked because hyperthyroidism may also lead to hypercalcemia. A 99mTc-MIBI scan of the parathyroid glands is often negative when they are concomitant. CASE PRESENTATION: Here, we report a rare case of the coexistence of giant toxic nodular goiter and PHPT that had been ignored for many years but was successfully treated with an ultrasound-guided parathyroid adenoma microwave ablation (MWA)...

BACKGROUND: Nowadays, the Republic of Belarus belongs to the countries with sufficient iodine supply, which made it possible to reduce the incidence of non-toxic goiter and congenital hypothyroidism. However, even a slight change in iodine consumption influences the pattern of thyroid diseases. In addition to iodine deficiency, other environmental conditions, as well as genetic factors, play a significant role in the etiology of thyroid diseases. AIM: To analyze the dynamics of the main epidemiological indicators of benign thyroid diseases from 2009 to 2019 in the adult population of the Republic of Belarus, using the data of official state statistics...
