The incidence of thyroid cancer has been greatly increasing. Several studies aimed to investigate biomarkers for prediction of thyroid cancer. Some of these studies have suggested that thyroid autoantibodies (TAb) could be used as predictors of thyroid cancer risk, but the correlation between TAb and PTC is still a matter of debate. The aim of this study is to evaluate thyroid autoimmunity and TAbs in patients with PTC and benign multinodular goiter (MNG) to investigate if TAbs and autoimmune thyroid disease (ATD) could predict thyroid malignancy...

BACKGROUND AND PURPOSE: Although core needle biopsy was introduced as a diagnostic alternative to fine-needle aspiration, the utility and safety of core needle biopsy for thyroid nodules in a large population has yet to be studied comprehensively. We evaluate core needle biopsy yields on a large-scale basis to investigate its potential in the preliminary diagnosis of thyroid nodules. MATERIALS AND METHODS: Between March 2005 and December 2013, 2448 initially detected thyroid nodules from 2120 consecutive patients who underwent core needle biopsy were retrospectively evaluated...

The brominated flame retardant TBECH is used as an additive to delay ignition and inhibit fires in construction materials and consumer goods. Trends in human exposure are not clear, although humans may be exposed to TBECH via indoor dust and air. In birds and fish there is some evidence of disruption in endocrine and reproductive parameters due to TBECH. In vitro studies indicate that TBECH is an androgen receptor agonist. In this study rats were exposed to 0, 10, 50, 250, 1250 or 5000mg/kg technical TBECH for 28days in diet, corresponding to 0, 0...

Thyroid carcinomas are the most common endocrine malignancy. Inconclusive results for the analysis of malignancies are an issue in the diagnosis of thyroid carcinomas; 20% of thyroid cancer diagnoses are indeterminate or suspicious, resulting in a surgical procedure without immediate need. The use of Raman spectroscopy may help improve the diagnosis of thyroid carcinoma. In this study, 30 thyroid samples, including normal thyroid, goiter and thyroid cancer, were analyzed by confocal Raman spectroscopy. Principal component analysis (PCA), linear discriminant analysis (LDA) with cross validation and binary logistic regression (BLR) analysis were applied to discriminate among tissues...

Accumulating evidence suggests that long noncoding RNAs (lncRNAs) play an important role in oncogenesis and tumor progression. However, our knowledge of lncRNAs in thyroid cancer is still limited. To explore the crucial lncRNAs involved in oncogenesis of papillary thyroid cancer (PTC), we acquired data of differentially expressed lncRNAs between PTC tissues and paired adjacent noncancerous thyroid tissues through lncRNA microarray. In the microarray data, we observed that a newly identified lncRNA, HIT000218960, was significantly upregulated in PTC tissues and associated with a well-known oncogene, high mobility group AT-hook 2 (HMGA2) gene...

BACKGROUND AND OBJECTIVES: Surgical complications delay adjuvant therapy in oncology patients. Current literature remains unclear regarding resident effect on postoperative outcomes, with inappropriate coverage possibly endangering patients in spite of attending oversight. We assessed resident postgraduate year (PGY) effect on 30-day overall morbidity in cancer patients undergoing major intra-abdominal and non-abdominal surgery. METHODS: Patients undergoing non-emergent major intra- and extra-abdominal operations from 2005-2012 were queried using the American College of Surgeons' National Surgical Quality Improvement Program...

CD40, a tumor necrosis factor receptor, is a major immune-modulating susceptibility gene for Graves' disease (GD) as well as for a variety of other autoimmune diseases. Its broad association with autoimmunity underscores its paramount role in the development of a normal adaptive immune response, primarily in coordinating effective antigen presentation. The molecular pathways by which CD40 activation in the thyroid induces GD are unknown. In this study, we investigated whether NF-κB, a ubiquitious family of transcription factors, mediates the downstream effects of thyroid-specific CD40 activation...

We report a case of a mediastinal mass indenting the left lateral tracheal wall of a 35-year-old male who presented with weight loss, cough and breathlessness. Flow volume loop and thyroid function tests were normal and thyroid peroxidase antibodies were negative. Technetium scintigraphy and positron emission tomography both showed no uptake. Endobronchial ultrasound-guided fine needle aspiration confirmed ectopic mediastinal thyroid tissue. Mediastinal ectopic thyroid tissue is very rare. Most patients are asymptomatic and euthyroid with positive signals on scintigraphy...
