Filter by:New devices and techniques are coming into use everyday. Ultrasonic dissectors (UDs) are such new devices which is a practical alternative to the usage of scalpel and sutures. UD's cause overheating of neighboring tissues in an area of 1 to 3 millimeters. Due to the generated heat UDs might cause nerve injury. The investigators would like to see if usage of UDs during thyroidectomy poses a risk for superior laryngeal nerve injury compared to conventional thyroidectomy.
Background : The use of suction drains in thyroid surgery is common practice in order to avoid haematoma or seroma, as well as to identify promptly the onset of haemorrhaging that might compromise the patient's airway. The aim of this study to determine the effects of routine drainage compared to no drainage in thyroidectomy patients. Study Design : Total of 400 patients who undergoing total thyroidectomy or lobectomy for thyroidal disorders will be randomly allocated to be drained or not. Postoperative ultrasonographic (USG) neck examination will be performed for all patients on postoperative 24th hour by the same ultrasonologist each time. Postoperative pain, complications and hospital stay will be recorded. The statistical analysis will be performed and p<0,05 will be accepted as an important statistical value (SPSS 16.0 for Windows).
This single-blind prospective randomized study was designed to assess the efficacy and safety of the use of Surgicel® compared to the use of conventional surgical procedures (ligatures and bipolar electrocautery alone) to achieve hemostasis in thyroid surgery
The investigators will dose galectin 3 in plasma and water rinse of the needle aspiration biopsy in patients with thyroid nodules. The investigators aim to show that preoperative dosage of the galectin 3 could provide good diagnosis of malignant versus benign thyroid cancer.
The extent of thyroid resection in Graves' disease remains controversial. The aim of this study was to evaluate long-term results of bilateral subtotal thyroidectomy versus total thyroidectomy in patients with Graves' ophthalmopathy.
Injury to the external branch of the superior laryngeal nerve (EBSLN) during thyroidectomy results in lowered fundamental frequency of the voice and worsened voice performance in producing high-frequency sounds. It remains unclear if use of intraoperative nerve monitoring (IONM) can improve clinical outcome of thyroidectomy in terms of preserved individual voice performance. This study was designed to test that hypothesis.
Patients with hyperthyroidism and/or goiter are evaluated with blood samples and scintiscan before they are treated with radioiodine for their thyroid disease. Because the investigators do not get a histologically/final diagnosis the investigators want to make sure, that the patients treated do not have a thyroid cancer when treated. The investigators have found that thyroid cancer is not overlooked.
The hypothesis of the study is that among patients that do not develop overt hypothyroidism after hemithyroidectomy, weight gain is a clinical manifestation of a postoperatively lowered set point of thyroid function - even if the thyroid function is lowered within the laboratory reference range. The investigators refer to this hypothesized condition as individual subclinical hypothyroidism. Thyroid hormones are major regulators of mitochondrial function and subclinical hypothyroidism affects mitochondrial activity. The aim of the study is to examine if a lowered set point of thyroid function after hemithyroidectomy can be measured in the mitochondrial function, the body weight and the basal oxygen consumption.
Many school children in Ethiopia and their mothers are known to be iodine deficient. Prevalence in the Amhara region is around 29%. Micronutrient Initiative, a development organization based in Ottawa, plans to help iodize the salt by providing iodization machines and iodine to the salt producers in Lake Afdira where salt is produced and distributed to the population of Ethiopia. Although it is generally assumed that iodine is important for cognitive development, very few studies examining the effects of iodized salt have been conducted. Studies using a single dose of iodine capsules with children 6 to 12 years showed mixed outcomes with approximately 25% yielding positive outcomes for the intervention children. Sixty districts in Amhara will be randomly selected and randomly assigned so that half receive early delivery of iodized salt. Approximately 6200 mothers and their children 6-, 18-, or 60-months old will be recruited from 1-2 villages in each of the 60 districts, with the help of government-paid Health Extension Workers, for a 12-mo longitudinal study starting in May 2011, prior to the introduction of iodized salt. These same mothers and children will be visited 12 months later for repeated measures. Measures include nutritional status such as height and hemoglobin, along with iodine sufficiency (e.g., goitre, urinary iodine, thyroglobulin), and child development (Bayley Scales of Infant and Toddler Development III, Wechsler Preschool and Primary School Intelligence test for older children). Comparisons will be made within and between groups to determine whether iodized salt has an effect on children's mental development.
The main objective is to compare 12 month complication rates between a new surgical method for thyroidectomy (robot-assisted endoscopic thyroidectomy via a sub-clavical approach) and open thyroidectomy.
