To evaluate the inflammatory activity in thyroid associated ophthalmopathy (TAO) by 99mTc-diethylene triamine pentaaceticacid (99mTc-DTPA) orbital single-photon emission computed tomography (SPECT)/CT.
 Methods: A total of 48 patients were enrolled from Xiangya Hospital of Central South University between October 2016 and March 2017. According to clinical active score (CAS), 93 eyes were divided into a TAO active group (n=72) and a TAO inactive group (n=21). All patients underwent 99mTc-DTPA orbital SPECT/CT examination, and the DTPA uptake in extraocular muscle belly was supposed to be positive...

Anaplastic thyroid cancer is an aggressive and highly lethal disease with poor outcomes and resistance to therapy. Despite multimodality treatment including radiation therapy and chemotherapy, response rates remain below 15% with a median time to progression of less than 3 months. Recent advances in radiotherapy delivery and gene-expression profiling may help guide patient selection for personalized therapy. The purpose of this study was to characterize the response to radiation in a panel of ATC cell lines and to test alternative radiotherapy fractionation schedules for overcoming radioresistance...

Graves´ disease is an autoimmune disorder, which is characterized by stimulatory antibodies targeting the human thyrotropin receptor (TSHR), resulting in hyperthyroidism and multiple organ damage. The disease can be modelled in mice using adenoviral immunizations with the extracellular A subunit of the TSHR, which induces a long-term stable disease state. TSHR binding cAMP-stimulatory antibodies, thyroid enlargement, elevated serum thyroxin levels, tachycardia, cardiac hypertrophy and orbitopathy are observed in these Ad-TSHR-immunized mice...

Autoantibodies to the thyrotropin hormone receptor (TSH-R) are directly responsible for the hyperthyroidism in Graves' disease and mediate orbital manifestations in Graves' orbitopathy (otherwise known as thyroid eye disease). These autoantibodies are heterogeneous in their function and collectively referred to as TRAbs. Measurement of TRAbs is clinically important for diagnosis of a variety of conditions and different commercial assays with high sensitivity and specificity are available for diagnostic purposes...

Thyroid autoimmunity is characterized by a large number of identified factors, and determining the relative importance of genetics and environment, for instance, can be difficult. In addition, the definition and progression of the individual diseases can also be challenging, and questions such as "when to begin treatment" or even "should treatment be begun" can be problematic. One approach to handling situations in which there are many factors is utilizing mathematical modeling. In a model, quantities that are clinically measurable are related through equations, based on known and inferred relationships between the systems involved...

PURPOSE: Thyroid autoimmunity affects approximately 5% of the population, and its investigation relies heavily on the use of autoantibodies. Thyroid stimulating hormone receptor (TSHR) autoantibodies (TRAb) play a central role in the evaluation of Graves disease (GD), Graves ophthalmopathy (GO) and pretibial myxedema (PTM). However, there is still controversy regarding overall TRAb assay diagnostic accuracy and their prognostic utility. METHODS: We reviewed and analyzed the literature reporting TRAb assays and their clinical utility...

PURPOSE: To critically review the published literature on orbital radiotherapy as a treatment modality for thyroid eye disease (TED). METHODS: A systematic review and analysis of the relevant published literature was performed. RESULTS: Thyroid eye disease is an autoimmune condition that is amenable to treatments that modulate the immune response, including orbital radiotherapy (ORT). Ideal candidates for ORT are patients in the early, active phase of TED with moderate to severe, or rapidly progressive, disease, including patients with significant motility deficits and compressive optic neuropathy...

Improvements in risk stratification have identified three distinct groups of patients with differentiated thyroid cancer. Those at highest risk who require intensive treatment, those at almost no risk who can safely be managed with a conservative approach and a remaining low risk group. This low risk group are at very low risk of death but are at risk of recurrence. Changes in international guidelines now consider such patients as potential candidates for management with thyroid lobectomy rather than total thyroidectomy and radioactive iodine...

The metastatic disease from thyroid cancer represents a complex clinical scenario, which mandates a case-based multi-disciplinary approach in tertiary referral centers. Direct localised treatments such as minimally invasive interventional radiology procedures can play a vital role in providing a timely palliative or curative treatment in accordance with the patients' clinical status. In this narrative review, we present the current status of interventional radiology treatments for the management of thyroid cancer distant metastases...

Thyroid function has an important role on body weight regulation. However, the impact of thyroid function on weight loss after bariatric surgery is still largely unknown. We evaluated the association between preoperative thyroid function and the excess weight loss 1 year after surgery, in 641 patients with morbid obesity who underwent bariatric surgery. Patients with a history of thyroid disease, treatment with thyroid hormone or antithyroid drugs and those with preoperative evaluation consistent with overt hypothyroidism or hyperthyroidism were excluded...

OBJECTIVE: Thyrotoxicosis is established risk factor for osteoporosis due to increased bone turnover. Glucocorticoids often administered for Graves' orbitopathy (GO) have additional negative effect on bone mineral density (BMD). Our aim was to examine the influence of thyroid hormones, TSH, TSH-receptor antibodies (TRAb) and glucocorticoid treatment on bone in women with Graves' thyrotoxicosis and Graves' orbitopathy (GO). SUBJECTS AND METHODS: Forty seven women with Graves' disease, mean age 55...

Some comorbidities, such as hypertension, are associated with higher von Willebrand factor (VWF) levels in the general population. No studies have been conducted to assess this association in patients with von Willebrand disease (VWD). Therefore, we studied this association in patients with type 1 (n = 333) and type 2 (n = 203) VWD from the 'WiN" study. VWF antigen (VWF:Ag) was higher in type 1 VWD patients with hypertension [difference: 0·23 iu/ml, 95% confidence interval (CI): 0·11-0·35], diabetes mellitus (0·11 iu/ml, 95% CI: -0·02 to 0·23), cancer (0·14 iu/ml, 95% CI: 0·03-0·25) and thyroid dysfunction (0·14 iu/ml, 95% CI: 0·03-0·26) than in patients without these comorbidities (all corrected for age, sex and blood group)...
