Active clinical trials for "Thyroid Diseases"

Breast cancer and thyroid disorders are important health challenges commonly encountered in women. The relationship between both conditions still remains unknown. In this study, the frequency of thyroid diseases was investigated in breast cancer patients

Papillary cancer is a disease that spreads through lymphatic ways and its treatment is surgery. We performed prophylactic central dissection in addition to bilateral total thyroidectomy in patients with bethesda 5 and bethesda 6 biopsy results. We evaluated the pathology results retrospectively.

Thyroid cancer (TC) is the most common endocrine malignancy. The association between inflammation and cancer is well established but the association between thyroiditis (inflammation of thyroid gland) especially Hashimoto's thyroiditis (HT) and thyroid cancer remains controversial. Chronic inflammation leads to a repeated cycle of cellular damage and subsequent healing which contributes to inappropriate cell proliferation and subsequent neoplastic transformation. One of the most common forms of Thyroiditis is Hashimoto's thyroiditis which is a chronic autoimmune inflammatory disease affects almost 5% of the population and is more common in women. For the first time, Dailey and Lindsay reported in 1955 an increased association between Hashimoto's Thyroiditis (HT) and thyroid cancer. They reported 35 thyroid cancers in 278 patients with Hashimoto's Thyroiditis, a prevalence of 17.7% which they considered higher than the general population . Since then, various studies have been done, some studies have reported an increased risk of malignancy in Hashimoto's thyroiditis; others have failed to find an association. Most of the studies that have been done to identify the association between Hashimoto's thyroiditis and thyroid cancer are retrospective. The purpose of this pilot case-control study is to identify the association of Hashimoto's thyroiditis and thyroid cancer, to determine if the presence of Hashimoto's thyroiditis has any affect on the complication of thyroidectomy and prognostic factors of thyroid cancer.

The standard surgical treatment for highly differentiated papillary thyroid cancer > 10 mm according to recent national and international guidelines, is total thyroidectomy and central lymphnode clearance, and for patients with cytology indicating thyroid neoplasia of unclear malignant potential hemithyroidectomy on the side of the tumour. The study investigates if the sentinel lymphnode (SN) Reliably (with high sensitivity and specificity), can predict the pathological findings of the lymphnodes in the central compartment in patients with highly differentiated papillary thyroid cancer Is useful to aid in the final diagnosis and staging of thyroid neoplasias of unclear malignant potential, and could be used to select patients for further central lymphnode revision.

New haemostatic techniques have been developed with the advent of laparoscopic surgery. Among other things, ultrasound instruments have been used for the dissection, division and coagulation of vessels and other tissue. Previous studies in Thyroidectomy observed a clinically and economically significant reduction in operating time with no increase in the complication rate when the Harmonic device has been used. The aim of the present clinical trial is to evaluate potential advantages of a new Harmonic device (FOCUS), developed especially for Thyroid procedures, in the use of HS in thyroidectomies when compared with EC in terms of operative time, number of ligatures, QoL, blood loss, pain intensity at the surgical site, amount of drainage, and complications, including the incidence of RLN palsy and hypoparathyroidism.

This study was designed to evaluate the incidence of both, inherited and adquired thrombophilia, and thyroid autoinmunity in unknown infertility (UI), implantation failure (IF) and recurrent miscarriage (RM). To focus on these particular disorders and to rule out another potential confounding variables, 4 particular groups of women were created. Only young women (< 38 years old), patients whose previous preimplantation genetic screening (PGS) cycles displayed an acceptable rate of aneploidies, and women without organic uterine abnormality, autoimmune disease or endocrine disorder were included in the study.

Overt hyperthyroidism and hypothyroidism are associated with inverted hemodynamic changes.Regional blood flow disturbances (including intrathyroidal) were also reported in these thyroid disorders. The purpose of this study is to investigate the thyroid vascularity and blood flow by Color Flow Doppler Sonography in patients with subclinical thyroid dysfunction

Hashimoto Thyroiditis (HT) and Graves Disease (GD) are known to be caused by abnormal immune response against self cells and tissues. Epigenetics is a novel field of biology studying the mechanisms by which the environment interacts with the genotype to produce a variety of phenotypes through modifications to chromatin that do not directly alter the DNA sequence. A very limited number of epigenetic studies have been published in patients with HT and GD so far. Therefore, the purpose of this study is to analyze DNA methylation status in White Blood Cells (WBCs) within the promoter regions of genomic sites that have been previously identified as susceptibility loci or sites for autoimmune thyroid disease, such as the CD40L, FOXP3, CTLA4, PTPN22, IL2RA, FCRL3 and HLADRB1 genes.

Magnetic resonance imaging (MRI) is a diagnostic technique that takes pictures of organs of the body. It uses magnetic fields and radio waves that cannot be felt. Perfusion MRI uses faster imaging. It also includes a contrast material that is given by vein. This makes specific organs, blood vessels, or tumors easier to see. Diffusion MRI lets us measure the motion of water in the tumor. Perfusion and diffusion MRI give extra information which is not available with the regular MRI. A regular MRI only shows pictures of the tumor. Thyroid MRI scans are not part of the current standard of care. The purpose of this study is to see if new MRI methods can give us more information about the tumor.

This study will investigate the usefulness of an optical probe in the differentiation of thyroid cancer from normal thyroid tissue in a thyroidectomy specimen.
