Filter by:The purpose of this study is to determine the safety and effectiveness of 2 different doses of modified-release recombinant human thyroid stimulating hormone (MRrhTSH) when administered with radioiodine in patients with multinodular goiter, a condition that involves the enlargement of the thyroid gland. We will also evaluate the safety and effectiveness of radioiodine therapy alone in these patients. The goal of the treatment is to determine if there was a reduction in the size of the goiter and to study if goiter symptoms have improved after 6 months and after 36 months.
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.
Primary objective: - To evaluate change in total volume of all nodules. Secondary objectives: - To evaluate change in goiter volume after a 12-months treatment, number of nodules and echogenicity of nodules.
The study aims at clarifying (in a randomized, double-blinded design): 1. Whether stimulation with 0.1 mg rhTSH 24, 48 or 72 hours before induction of a 131I-tracer dosis increases the 131I uptake in patients with atoxic multinodular goitre and to study which time interval is the most optimal (Part I) 2. Whether patients suffering from atoxic multinodular goitre obtains a corresponding goitre reduction compared with a control group when stimulating with 0.1 mg rh TSH 24, 48 or 72 hours before 131I therapy and when reducing the thyroid radiation dose to 50 Gy (Part II) The two studies will be carried out successively on the same patient population. The 131I uptake will be carried out first followed by the I therapy itself. The patients are compared with a placebo-treated control group going through the same course of treatment, but the 131I dosis will be 100 Gy (standard treatment). After the 131I therapy, all patients are followed during one year with a regular ultrasound scan of the thyroid gland and control of the metabolic status. The patient satisfaction is monitored by the use of a visual-analogue-scale.
To date, there have been no comprehensive studies on swallowing function in patients undergoing surgery for multinodular goiter. We hypothesize that 1. Multinodular goiter has significant effect on swallowing function in symptomatic and asymptomatic patients, which can be demonstrated by a standardized questionnaire and a formal swallowing evaluation and 2. Surgery will improve swallowing function as measured post-operatively by these same parameters. Patients with multinodular goiter will be asked to fill out a validated survey (SWAL-QOL) on swallowing function in addition to undergoing a formal swallowing evaluation before and after surgery for multinodular goiter (subtotal thyroidectomy) and compared to patients undergoing total thyroidectomy for follicular cancer and less extensive thyroid surgery for other benign processes (lobectomy or lobectomy plus isthmusectomy).
The trials in this protocol deals with the effect of pretreatment with rhTSH on radioiodine treatment of thyroid size and function, in patients with nontoxic and toxic nodular goiter. It is an introduction of a novel principle, based on prospective, randomized double blind investigations. Attached to this, we investigate the acute effects of rhTSH on thyroid size (measured by ultrasonography), both in healthy individuals and in patients with nontoxic nodular goiter. Thus, the investigations are divided into 4 categories listed below: 1. Prospective randomized double blind study of pretreatment with 0.3 mg recombinant human TSH for the effect of radioiodine in nontoxic multinodular goiter. 2. Prospective randomized double blind study of the pretreatment with 0.3 mg recombinant human TSH for the effect of radioiodine on thyroid size and function in patients with a very large (>100 ml) nontoxic or toxic goiter. 3. Does administration of 0.9 mg recombinant human TSH affect thyroid function and volume in healthy individuals? A randomized double-blind cross-over trial. 4. Does administration of 0.3 mg recombinant human TSH affect thyroid function and volume in healthy individuals and in patients with multinodular non-toxic goiter? A randomized double-blind cross-over trial. As a final note we investigate, in a pilot-study; 5. The influence of rhTSH on thyroid radioiodine uptake in patients with hyperthyroidism treated with continuous block-replacement therapy.
