Active clinical trials for "Thyroid Diseases"

The influence of thyroid autoantibodies on thyroid function in pregnancy after fertility treatment is not well known. The objectives of the present study are: To monitor the course of thyroid function during pregnancy and to compare between women with and without thyroid autoantibodies. Compare pregnancy outcome between women with and without thyroid antibodies

The aim of this study was to evaluate the usefulness of photoacoustic imaging in thyroid nodules. In addition, we would like to confirm the relationship between the results of photoacoustic imaging and histopathologic findings when thyroid nodules were diagnosed as thyroid cancer.

Nowadays, 5-step modified Cormack-Lehane scoring (MCL) system is frequently used in the observation of laryngeal structures by direct laryngoscopy. Upper airways with flexible fiberoptic laryngoscopy are routinely evaluated in patients who are predicted to be difficult intubation, who have undergone head or neck surgery previously and who require vocal cords to be evaluated preoperatively. During this examination patients are awake; so the upper airway and the muscles in the base of the mouth have normal tonus and airway reflexes are active. When general anesthesia is applied to the same patients during direct laryngoscopy, the laryngeal view may not be as clear as awake flexible fiberoptic laryngoscopy, since a tonus loss occurs in the muscles after general anesthesia. The aim of the study is to investigate the relationship between preoperative awake flexible fiberoptic laryngoscopy performed by ear- nose- throat (ENT) physicians in patients undergoing total thyroidectomy, and the MCL score during direct laryngoscopy after general anesthesia in the same patients. Thus, investigators would like to determine the reliability of airway evaluation with preoperative awake flexible fiberoptic laryngoscopy in predicting intubation conditions during tracheal intubation under general anesthesia.

The incidence of Thyroid Cancer (TC) has increased over the last thirty years, in France and worldwide. This increase is mainly due to good prognosis microPapillary TC (mPTC). Sixty percent of diagnosed cancers are considered as over-diagnosed, leading to an over-treatment of these cases. The increase of diagnosis of mPTC and its treatment inevitably leads to an increase of medical resources consumption and corresponding costs. The primary aim of this study is to estimate the cost related to different care management pathway of TC patient during a lifetime period using a multi-state Markov model. This is a retrospective, observational population based cohort study, using data from a cohort study of TC patients implemented by the ONCOMIP network which initially aimed to perform an audit of clinical practices for the management of TC, and from database of the French social health insurance of Midi-Pyrenees region to calculate observed costs of TC management during 24 months.

The purpose of this study is to evaluate the psychological status of Thyroid Related Eye Disease.

Thyroidectomy is one of the commonest elective surgeries in surgical practice nowadays. It is associated with wide range of complications, from unnoticed events up to lifelong problems and even life-threatening complications. The most troublesome are bleeding, nerve injury and hypocalcemia. The current study was conducted to report the incidence and predictive factors for perioperative complications, aiming to point out preventive measures.

In this study, the investigators look at the genetic expressional alteration which influenced on the early lateral neck node metastasis in thyroid papillary microcarcinoma.

This will be a population based study looking at the prevalence of thyroid disorders in Malaysia (including hypo- and hyperthyroidism, subclinical hypo- or hyperthyroidism) and its association with different ethnicity and iodine status. The study will also look at genetic susceptibility for autoimmune thyroid disorders in the Malaysian population General hypotheses: The prevalence of thyroid disorders in Malaysia is 10% for hypothyroidism and 2% for hyperthyroidism Hypo- and hyperthyroidism is associated with iodine status in our population There are different susceptibility gene for autoimmune thyroid disorder in different ethnicity in our population

This protocol will evaluate microRNA biomarkers in blood and fine-needle aspirate biopsies (FNAB) of thyroid nodules. MicroRNA profiles will be determined and evaluated for their utility in pre-operative diagnosis, in particular to distinguish benign from malignant throid neoplasms. Post-surgical fresh-frozen thyroid cancer tissue will be assessed for somatic mutations, mRNA, and microRNA expression patterns. FFPE tissue will be used to obtain H&E and unstained slides to specific biomarker results using immunohistochemistry.

This study will investigate the usefulness of an optical probe in the differentiation of thyroid cancer from normal thyroid tissue in a thyroidectomy specimen. This is the next step in the research that this team has conducted through our prior Institutional Review Board (IRB)H-28135, in which the investigators successfully demonstrated that use of the optical probe readings on thyroid specimens ex vivo could successfully discriminate benign from malignant disease. The Elastic Scattering Spectroscopy (ESS) probe has also been IRB approved and a clinical trial conducted in vivo at Boston University/Boston Medical Center by Dr. Satish Singh and Dr. Irving Bigio. The investigators intend to now bring this project to the clinical setting of thyroid disease. The optical real-time readings will be compared to the histological analysis from the same area. Subjects already undergoing thyroid biopsy for thyroid disease including thyroid nodules, thyroid cancer and thyroid goiter with nodules will be eligible to participate. During the already scheduled thyroid procedure using a fine needle aspiration biopsy needle, optical readings will be taken from the thyroid gland and these same areas will then be analyzed in the usual standard fashion. The reading will then be correlated with the histological results. In addition, if lymph nodes are biopsied as part of the evaluation they will also be tested prior to histological standard processing. All specimens and data will be de-identified once data collection and analysis is complete. Our goal is to use optical real-time readings to improve the differential diagnosis of benign from malignant thyroid nodules and avoid surgery for the purpose of diagnosis alone.
