Filter by:Physiological changes necessitate the use of pregnancy-specific reference ranges for TSH and FT4 to diagnose thyroid dysfunction during pregnancy. Although many centers use fixed upper limits for TSH of 2.5 or 3.0 mU/L, this may lead to overdiagnosis or even overtreatment. The new guidelines of the American Thyroid Association have considerably changed recommendations regarding thyroid function reference ranges in pregnancy accordingly. Any hospital or physician that is still using the 2.5 or 3.0 mU/l cut-off for TSH during pregnancy should evaluate their own lab-specific cut-offs. The investigator's objective is to establish a rational reference range of serum TSH for diagnosis of subclinical hypothyroidism in the first and second trimester of pregnant women in west Black Sea region in Turkey.
This study evaluates the combination of lenvatinib with denosumab in bone-predominant metastatic Radioiodine Refractory Differentiated Thyroid Carcinomas. All patients will receive this combination of treatments.
The feasibility and effectiveness of Reversed Tracking Method for the identification and protection of extralaryngeal nerve branches in thyroid surgery were analyzed. Evidence-based medical evidence was used to evaluate the importance of EBSLN recognition and protection in thyroid surgery.
Background: Most patients with thyroid cancer have a long life expectancy, and it has been assumed among health professionals that therefore the quality of life (QOL) is good. Some European studies have shown that the quality of life among thyroid cancers is worse than the general population, and almost as low as other cancer diagnoses, with a worse prognosis and a more burdening treatment. Aim: To examine prospectively the quality of life in participants undergoing diagnostic thyroid surgery and participants undergoing surgery for certain thyroid cancer. By examining both groups we wish to find answers if quality of life is affected, and if so - mostly affected by the diagnosis or the surgery itself. Methods: Participants enroll the study after informed consent, and quality of life will be assessed using quality of life questionnaires EORTC QLQ C30, EORTC THY 47 and EORTC FA12 before surgery, and 6 and 12 months after surgery. This study will form two main groups of participants; with and without thyroid cancer.
This is an observational study of voice outcomes in participants following thyroidectomy or another head and neck surgery that does not involve risk to the larynx other than risks incurred due to intubation alone. These comparative (non-thyroidectomy) surgeries would not be expected to interfere with the primary nerves involved with voice production, so they would help to better understand the effect of intubation alone on voice outcomes.
The purpose of this study is to evaluate a new diagnostic imaging test, positron emission tomography (PET), with a different radioactive form of iodine called iodine-124. This form is able to accurately measure the amount of radioactive iodine uptake in the cancer. If the new test determines sufficient radioiodine uptake in the cancer, treatment will continue as usual. However, if the new test shows only low radioiodine uptake, a decision may be made that the benefit from radioiodine therapy is insufficient and that another form of therapy is preferred.
The prevalence of thyroid cancer has increased in recent decades. Patients with thyroid cancer need to choose between Thyrogen® injection and Eltroxin® withdrawal before radioiodine therapy or scan. This is a prospective, observational study, aiming to observe the difference of metabolic profiles between patients choose Thyrogen® injection and Eltroxin® withdrawal.
Patients in our department endoscopic thyroidectomy were randomly divided into high position and low position established operating space group established operating space group. The thyroid size, patient BMI, operation time, and intraoperative blood loss were compared between the two groups.
Prospective randomized open phase III non-inferiority trial in cT1bT2N0 papillary thyroid carcinoma comparing: total thyroidectomy alone (experimental group) versus total thyroidectomy + Prophylactic Neck Dissection PND (reference group). Pre-registered patients will be randomized before surgery for tumors with class-6 cytology (Bethesda) or in the operating room after confirmation of malignancy by frozen section analysis for tumors with class-5 cytology.
In recent years, the application of intraoperative recurrent laryngeal nerve monitoring in thyroid surgery has greatly reduced the complications of recurrent laryngeal nerve injury. The use of intraoperative neurological monitoring requires the reduction of the dose of neuromuscular blockade, which often leads to muscle tremors during the application of electrical energy, which affects the fine separation around the muscles. This study explored the effect of local application of lidocaine on reducing muscle tremor during surgery and its optimal dose.
