Filter by:It has been shown that insulin might be involved in the pathogenesis of thyroid growth. Objective To evaluate the impact of IR and metformin use on the volume of benign thyroid nodules (TNs). Methods A randomized clinical trial to placebo (P) or MTF use. Previous fine needle aspiration confirming the diagnosis is necessary to inclusion. Patients will receive similar tablets of MTF and placebo and instruct to take 3 tablets/day of MTF (500mg/tablet). Thyroid volume, as TN volume, will be assess by ultrasound, both in the beginning, six months and one year after randomization, by the same researcher blinded regarding location group. Blood samples to measure: TSH, FT4, TPO-Ab, lipid profile, glucose and insulin were done after 8h fasting.
This clinical trial studies how well ultrasound elastography works in assessing the cancer status of potentially malignant thyroid nodules.
The investigation of thyroid nodules is limited by the fact that up to 49% of the fine needle aspirations (FNA) performed are of "indeterminate cytological signification". Moreover, no fully reliable molecular marker for thyroid cancer have been described. The goal of this project is to study the expression of a specific kind of protein convertase in benign and in malignant thyroid nodules to determine its potential as a biomarker.
Thyroid surgery has been developed as a new technique for zero scar in surgery by applying transoral endoscopic thyroidectomy with sublingual approach. The new technique is locating the surgery which pierced through floor of mouth, cause severe tissue damage, high complication, and conversion rates to open surgery and surgical difficulties due to limitation of movement. Nevertheless, each report is still including small number of patients. Recently, the transoral endoscopic thyroidectomy vestibular approach (TOETVA) has been proven feasible and safe in several overseas centers. Moreover, a successful TOETVA case was reported in local media in the late last year. Hence, this study is for evaluating the feasibility and safety of the TOETVA prospectively at a tertiary referral center in Hong Kong. The following are the procedure of the study: 1. Recruit patients from the clinic. 2. Patients will receive treatment within 3 months 3. Patients will have different assessments like Ultrasonography assessment, Fine needle biopsy, Direct laryngoscopy, and Cosmectic scoring in Pre-operation, post-operation 2 week, post 1 month, post 3 month, post 6 month and post 12 month. 4. Patients will be monitoring by the same team after the study.
Although it is now recognized that a variety of respiratory abnormalities, such as diaphragmatic dysfunction, can be present in primary hypothyroidism and reverse with adequate hormone treatment, the role of thyroid hormone replacement therapy on respiratory system in patients with the nonthyroidal illness syndrome (NTIS) remains to be clarified. The NTIS has been found to be an independent risk factor for prolonged (> 13 days) mechanical ventilation. It is unclear, however, whether the NTIS is only a biochemical prognostic marker or it actually contributes to the development and progression of respiratory failure. The aim of this study will be to assess respiratory muscle function after thyroid hormone substitution therapy in mechanically ventilated patients with the NTIS.
Diabetes Mellitus is the most common disorder seen. The impact of this disease on the quality of life, and on morbidity and mortality through the complications that affect the small and large vessels resulting in retinopathy, nephropathy, neuropathy, and ischemic heart disease has been emphasized by the findings of the national commission (USA) on diabetes . So, there was curiosity to understand and learn the association of this disorder with another common endocrine gland function that is thyroid gland . The association between these two disorders has long been recognized although the prevalence of thyroid dysfunction in diabetic population varies widely between studies. With insulin and thyroid hormone being intimately involved in cellular metabolism and thus excess or deficit of these hormones result in functional derangement of the other . Diabetic patients have higher prevalence of thyroid disorder when compared with the normal population. Diabetic women are more frequently affected than men and hypothyroidism is more common than thyrotoxicosis. As Hyperthyroidism impairs glycemic control in diabetic subjects, while hypothyroidism may increase susceptibility to hypoglycemia thus complicating diabetes management so Severe diabetic complications where noted in patients with sub- clinical hypothyroidism . Sub-clinical hypothyroidism is an independent risk factor for development of diabetic nephropathy.
The purpose of this study is to test the safety of durvalumab (MEDI4736) and tremelimumab in combination with radiation therapy and find out what effects, if any, this combination has on people, and whether it improves overall survival.
This pilot clinical trial studies how will metformin hydrochloride works in mitigating the side effects of radioactive iodine treatment in patients with differentiated thyroid cancer. Metformin hydrochloride may reduce the metabolic activity of cancer cell and of surrounding supportive tissues.
As many as 70-85% subjects diagnosed with a follicular lesion on biopsy and undergoing surgery will have benign lesions verified by histopathology after surgery. Currently there is no method of pre-operatively diagnosing benign follicular lesions, as a result these subjects will have had surgery for diagnosis of a benign lesion. The aim of this study is to see whether shear-wave elastography, a new ultrasound technology can help pre-operatively diagnose benign follicular lesions. If successful, a lot of patients will not need surgery for the diagnosis of a benign lesion. The main goal of this study will be to evaluate the diagnostic accuracy of a new ultrasound technology (shear-wave elastography - SWE) for the diagnosis of malignancy in follicular lesions. Participants who have been diagnosed with a follicular lesion on thyroid biopsy and are scheduled for thyroid surgery will be eligible to participate. All participants will undergo a detailed ultrasound examination prior to their surgery. The results of the ultrasound will be compared with histopathology after surgery to test the diagnostic accuracy of SWE.
Background: Medullary thyroid cancer (MTC) is a tumor of the thyroid gland. Surgery is the only current treatment to cure it. The drug pembrolizumab (MK-3475) is a new type of cancer therapy. It works by allowing the immune system to detect and kill tumor cells. Objective: To test how pembrolizumab affects people with MTC and if it can offer them clinical benefit. Eligibility: People ages 18 and older with MTC Patients who have recurrent or metastatic MTC, for whom surgery is not a curative option Patients with some imaging evidence of MTC Patients with minimal symptoms related to MTC Design: Participants will be screened with: - Medical history - Physical exam - Blood, urine, and heart tests - Computed tomography (CT) scan or magnetic resonance imaging (MRI): They lie in a machine that takes pictures of the body. - Bone scan Participants will be put in a group based on their treatment history: - Group 1 if they have had an immune stimulating cancer vaccine - Group 2 if they have had no vaccine Participants will receive the study drug as a 30-minute intravenous (IV) infusion every 3 weeks. Treatment will continue for up to 2 years as long as they tolerate it and their disease does not get worse. Participants will have physical exams and blood tests on the day of each infusion. They will have CT and bone scans every 3 months. Participants may save biopsies before treatment and after starting treatment. Participants will have a final visit 3-4 weeks after stopping treatment. This will include a physical exam and blood and heart tests. After this study, participants can join a long-term follow-up study.
