Filter by:The objective of this observational study was to evaluate the effect of transverse and longitudinal sections on the measurement of thyroid nodule stiffness by shear wave elastography. The main questions it aims to answer are: (i) to compare the diagnostic efficacy of different section orientations of shear wave elastography for the diagnosis of benign and malignant thyroid nodules; (ii) to analyze the correlation between the two orientations of transverse and longitudinal sections of shear wave elastography; and (iii) to compare the reliability and consistency of the two orientations of transverse and longitudinal sections of shear wave elastography for the diagnosis of thyroid nodules. Participants will undergo routine ultrasound examination of the thyroid gland and shear wave elastography, and the measured modulus of elasticity of the nodules in both transverse and longitudinal sections will be recorded.
Ideally randomized controlled trials should be carried out to compare the cost-effectiveness between FNAC and watchful waiting but such studies are very difficult to conduct in practice because they require following up very large number of subjects for a long period of time. The aims are to determine the health-related quality of life (HRQOL) and HRQOL preference (utility) of patients undergoing watchful observation (no FNAC) and routine FNAC, and to determine the cost-effectiveness of two strategies in managing small incidental thyroid nodules for the Chinese population in Hong Kong.
One of the major side effects of surgery to remove the thyroid gland is transient (lasting for a short time) low calcium levels in the blood, or "hypocalcemia." Low calcium levels can cause symptoms such as numbness around the mouth, tingling or cramping in the hands and feet, severe muscle spasms, inability to breathe, or heart rhythm (heart beat) abnormalities. Severe symptoms are life threatening, so it is important to start the management of these symptoms in the hospital. Treating low calcium levels sometimes require patients to spend a few extra days in the hospital. The human body needs vitamin D to function and stay healthy. Vitamin D helps the body get the calcium needed to make strong bones and teeth. The purpose of this study is to determine if taking vitamin D before surgery to remove the thyroid gland affects whether or not you may have low calcium levels after your surgery and to test the hypothesis that those who are given the Vitamin D before surgery will have decreased hypocalcemia and a shortened hospital stay.
The study is an open, prospective multicenter study. According to the statistical sample size calculation 593 patients with thyroid nodules ≥ 5mm in size will be included in the study. Reference methods are cytology obtained by Fine needle aspiration biopsy (FNAB) or histology obtained by surgery. All patients will receive an B-mode and Duplex ultrasound examination of the thyroid gland, as well as Realtime Elastography of thyroid nodules. Results of B-mode and Duplex ultrasound are compared to Realtime Elastography to evaluate the additional value of Realtime Elastography in the diagnostic work up of thyroid nodules.
Define an ultrasound/elastography benignity criteria in strategy management of a patient population carries one or more thyroid nodules.
Systemic sclerosis (SSc) is a systemic disease that involves various organs such as the skin, kidneys, gastrointestinal tract and lungs. Dysfunction of the thyroid gland is prevalent in these patients and may be related to thyroid fibrosis or to thyroid autoimmune disease, i.e. hashimoto's thyroiditis. Thyroid nodules are prevalent in the general population, although some reports suggest they might be more frequent in patients with SSc. Hashimoto's thyroiditis, by itself, carries a higher risk for thyroid nodules and thyroid cancer. The aim of the study:To characterize sonographycally the thyroid gland of patients with SSc with and without Hashimoto's disease
Patients over the age of 18 with thyroid nodules scheduled for surgery will undergo EIS scan. Each node will be scanned and graded form 1-5 (1=benign, 5=malignant). Results will be compared with final histopathology.
Residents of certain villages in Kazakhstan were exposed during childhood to radioactive fallout from nuclear tests conducted at the Semipalatinsk Nuclear Test Site (SNTS) between 1949 and 1962. Radiation doses to the thyroid from external and internal (i.e., ingested) radiation sources deposited as fallout are of interest because they may be jointly and differentially associated with increased risk of thyroid disease in this population. Objectives: To collect information about factors influencing radiation dose to the thyroid gland in children of two ethnic groups who were exposed to radioactive fallout from nuclear tests at the SNTS between 1949 and 1962. The two groups are Kazakhs (historically nomadic herders) and Europeans (typically descendants of Russian and German farmers). Eligibility: Women 70 years of age and older who had children or provided care to children during the 1950s. Men age 70 and older who were engaged in farming and care of dairy animals at the time of the nuclear tests. Design: In focus group format, participants are interviewed to collect information on the following at the time of nuclear tests: - Dairy consumption; - Source, storage and availability of milk and milk products; - Time that children of different ages and ethnic groups spent indoors; - Building material of houses and schools; - Herding, grazing and supplemental feed of dairy animals.
Thyroidectomy is an operation that is commonly performed. After an operation a pressure dressing by Hypafix is usually used due to the belief that it will help to reduce complications such as post-operative bleeding or haematoma. However, the practice is uncomfortable to patients and makes it hard to detect early haematomas. We carried out a prospective randomised study to study the role of pressure dressing after thyroid surgery by evaluating the amount of fluids collected in the operative bed by ultrasonography compared with normal dressing.
