Treatment with amiodarone is associated with changes in thyroid function tests, but also with thyroid dysfunction (amiodarone-induced hypothyroidism, AIH, and amiodarone-induced thyrotoxicosis, AIT). Both AIH and AIT may develop in apparently normal thyroid glands or in the presence of underlying thyroid abnormalities. AIH does not require amiodarone withdrawal, and is treated with levothyroxine replacement if overt, whereas subclinical forms may be followed without treatment. Two main types of AIT are recognized: type 1 AIT (AIT 1), a form of iodine-induced hyperthyroidism occurring in nodular goitres or latent Graves disease, and type 2 AIT (AIT 2), resulting from destructive thyroiditis in a normal thyroid gland...

BACKGROUND: Thyrotoxicosis is a common disease resulting from an excess of thyroid hormones, which affects many organ systems. The clinical symptoms and signs are relatively nonspecific and can vary depending on age, sex, comorbidities, and the duration and cause of the disease. Several symptom rating scales have been developed in an attempt to assess these symptoms objectively and have been applied to diagnosis or to evaluation of the response to treatment. The aim of this study was to assess the reliability and validity of the Korean version of the hyperthyroidism symptom scale (K-HSS)...

BACKGROUND: Thyroid-stimulating hormone receptor (TSHR) gene mutations play a critical role in thyroid cell proliferation and function. They are found in 20%-82% of hyperfunctioning nodules, hyperfunctioning follicular thyroid cancers (FTC), and papillary thyroid cancers (PTC). The diagnostic importance of TSHR mutation testing in fine needle aspiration (FNA) specimens remains unstudied. METHODS: To examine the association of TSHR mutations with the functional status and surgical outcomes of thyroid nodules, we evaluated 703 consecutive thyroid FNA samples with indeterminate cytology for TSHR mutations using next-generation sequencing...

Subclinical hypothyroidism (SCH) is characterized by mild elevation of thyroid stimulating hormone (TSH) (range 5-10 μIU/ml) and normal free triiodothyronine (FT3) and free thyroxine (FT4). The cognitive function impairment is well known in thyroid disorders such as hypothyroidism and hyperthyroidism, but little is known about deficits in brain functions in SCH subjects. Also, whether hormone-replacement treatment is necessary or not in SCH subjects is still debatable. In order to have an insight into the cognition of SCH subjects, intrinsic and extrinsic functional connectivity (FC) of the resting state networks (RSNs) was studied...

Background Monopolar radiofrequency ablation is currently deemed an exotic treatment option for benign thyroid nodules in many central European countries. The aim of this study was to prospectively evaluate safety and efficacy of this method in a large patient cohort following its introduction in Austria. Patients and methods Peri- and post-interventional complications were analyzed for 277 patients. Efficacy was determined for 300 and 154 nodules at, respectively, 3 and 12 months post-treatment. All treatments were performed with an internally-cooled 18G radiofrequency electrode using a free-hand, so-called "moving-shot" technique following subcutaneous and local perithyroidal anesthesia...

BACKGROUND: Autoimmune thyroid disease affects 1% of the general population, and autoimmune thyroid antibodies are noted in up to 15%. OBJECTIVE: We hypothesized systemic sclerosis (SSc) is associated with higher prevalence of antithyroglobulin (anti-Tg) and anti-thyroid peroxidase (anti-TPO) antibodies) to justify monitoring of thyroid function for earlier detection and treatment. METHODS: Waikato Hospital SSc clinic patients were prospectively tested for thyroid function tests and antithyroid antibodies (ATAs)...

Whereas in regions with sufficient iodide intake treatment of thyroid nodules with levothyroxine has been almost completely abandoned and is also not further recommended by guidelines, medical treatment may be still indicated in Germany as recently demonstrated by randomized, placebo-controlled LISA study.A major reason for this is mild iodide deficiency in patients with thyroid nodules. In LISA study a combined therapy of levothyroxine and iodide resulted in an at least 50 % reduction of nodular volume in 21,6 % of treated patient compared to in only 5,2 % of placebo-treated patients...

Immune check point inhibitors have revolutionized the treatment of metastatic malignancies. They are a promising area in oncology and more drugs are likely to be available in the coming years. Along with the promise of better response oncologically, there is an increased incidence of endocrinopathies related to autoimmunity. This case report illustrates the dramatic development of hypothyroidism in a patient with underlying subclinical hyperthyroidism. It also suggests the potential pretreatment predictors of endocrinopathies related to these immune check point inhibitors...

BACKGROUND: Graves' is disease an autoimmune disorder of the thyroid gland caused by circulating anti-thyroid receptor antibodies (TRAb) in the serum. TRAb mimics the action of thyroid stimulating hormone (TSH) and stimulates the thyroid hormone receptor (TSHR), which results in hyperthyroidism (overactive thyroid gland) and goiter. Methimazole (MMI) is used for hyperthyroidism treatment for patients with Graves' disease. METHODS: We have developed a model using a system of ordinary differential equations for hyperthyroidism treatment with MMI...

Type 2 diabetes mellitus (T2DM) and thyroid disorders (TD) are the two most common endocrine disorders in clinical practice. Unrecognized thyroid disorders may adversely affect the metabolic control and add more risk to an already predisposing type 2 diabetes mellitus. The objective of the study is to find out the percentage of hypothyroidism and hyperthyroidism in patients with type 2 diabetes mellitus and non diabetic subjects. This cross-sectional study was conducted in the department of Biochemistry and outpatient Department of Endocrinology, BIRDEM General Hospital, Dhaka, Bangladesh from July 2014 to June 2015...
