Active clinical trials for "Goiter"

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.

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.

Observational study with non-inferiority, prospective, randomized (1: 1) and open-label medical device. The study has 2 treatment groups (HEMOPATCH® versus standard hemostasis).

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.

Regular thyroid diagnostics versus augmented thyroid work-up with additional I-124 PET/US fusion for metabolic-sonographic nodule allocation in patients with benign thyroid diseases

Study Design Multinodular Goiter (MNG) patients requiring surgery were referred to the Endocrine Surgery Unit. Indirect laryngoscopy was routinely performed preoperatively to assess normal motility in vocal folds (VF). Ultrasounds (US) study was performed the month previous to surgery to evaluate thyroid volume. Eligible patients met the following criteria: to have MNG, age between 18 and 80 and consent to be included in the study. Exclusion criteria included previous neck surgery, vocal fold impairment, permanent or transitory NSAID or analgesic treatment, coagulation disorders and any cognitive impairment. Eligible patients were proposed to enter a randomized study with 2 arms in which we compared the use of two harmonic scalpel devices: ACE14S and Harmonic Focus (Ethicon Endo-Surgery, Cincinnati, OH, USA). The main endpoint was operative time. Secondary endpoints were total and relative (%) time of use of the device along thyroidectomy, recurrent laryngeal nerve (RLN) injury and hypocalcaemia (both persistent or temporary), number of ligatures, length of skin incision, postoperative pain according to a visual scale of pain, QOL after thyroidectomy (EuroQOL) and budget impact analysis. All patients were operated on by 2 surgeons, one senior (responsible for the Endocrine Surgery Unit) and one junior under supervision. Randomization Randomization was performed the same day of surgery at the OR by using a closed envelope. Patients were randomized to Group I (ACE14S) or Group II (HF) and allocated in a 1:1 proportion; they reminded blinded until the end of the study about the device used. The haemostasis device was communicated to the surgeon previous to start surgery. Medical staff of the Endocrine Surgery Unit collected clinical data. Surgical Technique Total thyroidectomy (TT), defined as total bilateral extracapsular lobectomy 9, was performed using HF or ACE14S for vessel division. Monopolar and bipolar forceps for cutting and coagulation were routinely used. Ties were used under surgeon's criteria according to size of the vessels and/or the need to obtain haemostasis in the vicinity of the RLN when bipolar forceps were not considered safe enough.

The aim of the study is to investigate the influence benign non-toxic goitre and the surgical treatment hereof on the voice function before and 6 months following surgery.

In the last decades, thyroid cancer incidence has continuously increased all over the world, almost exclusively due to a sharp rise in the incidence of the papillary histologic subtype, which has the highest incidence of multifocality. Furthermore, Black Sea and Eastern European regions are both endemic and known to have been under the influence of Chernobyl nuclear explosion. Although overscreening might have a role in certain parts of the world, the predictors of malignancy such as family history, genetical disorders, previous radiation exposure, low iodine intake, diabetes and obesity, should also be taken into consideration in determining the extent of surgery.

Thyroid disorders are one of the most common endocrine problems in children and adolescents. Diagnostic considerations can be approached from the perspective of the goiter.A goiter, or thyromegaly, is an enlargement of the thyroid gland.Persons with enlarged thyroids can have normal function of the gland (euthyroidism), thyroid deficiency (hypothyroidism), or overproduction of the hormones (hyperthyroidism).
