Filter by:Intraoperative Neuromonitoring (IONM) was started to be used by surgeons to help prevent laryngeal nerve (RLN) damage during thyroid and parathyroid operations. IONM can be used to localize and identify RLN intraoperatively, to evaluate vocal function after thyroid resection, and to explain the mechanism of RLN injury. However, an important problem in the routine use of IONM is the effect of neuromuscular blocking agents (NMBAs). The use of NMBAs in general anesthesia is essential to provide clinically acceptable tracheal intubation conditions and to prevent laryngeal trauma. However, NMBAs may be the potential cause of a false-negative response during the IONM. Randolph et al. proposed short-acting 1-2 mg/kg succinylcholine for enough relaxation and the ease of electromyographic (EMG) endotracheal tube intubation during the IONM. However, succinylcholine, a depolarizing NMBA, is associated with various adverse effects such as cardiac arrhythmia, hyperkalemia, and malignant hyperthermia. Nondepolarizing NMBAs are widely used by most anesthesiologists due to their safe effects, but to the best our knowledge, there is no very short-acting nondepolarizing NMBA. This deficiency creates a problem because the dose and the time point of nerve stimulation are critical for a successful IONM. However, some studies have reported the feasibility of IONM following the administration of nondepolarizing NMBAs during a thyroid operation. Rocuronium is a short-acting and nondepolarizing NMBA type which is widely used for induction in general anesthesia. Although 0.6 mg/kg rocuronium is recommended for standard intubation dose, the ease of intubation can also be provided with 0.3 mg/kg rocuronium or 1.5 mg/kg succinylcholine. Therefore, the present study was designed to compare the effects of IONM with low and standard rocuronium doses in the induction of general anesthesia.
Researchers are trying to determine whether an exercise program reduces fatigue and improves physical activity in thyroid cancer patients.
This study utilizes a multi-institutional registry to describe the natural history of medullary thyroid cancer that has spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) in understanding disease management. The goal of this study is to learn about how medullary thyroid cancer develops and progresses.
The reason for this study is to see if the study drug selpercatinib is safe and more effective compared to a standard treatment in participants with rearranged during transfection (RET)-mutant medullary thyroid cancer (MTC) that cannot be removed by surgery or has spread to other parts of the body. Participants who are assigned to the standard treatment and discontinue due to progressive disease have the option to potentially crossover to selpercatinib.
Thyroid disorders are most commonly concomitant with prematurity and still remains a controversial topic. The incidence of a temporary form of hypothyroidism among preterm neonates is higher than in the general population. Transient prematurity hypothyroxinemia is defined as a temporary reduction in FT4 values without increase in TSH values. Currently, there is no consensus about normal thyrotropine (TSH) and free thyroxine (FT4) values in preterm infants. The aim of this study is to determine the volume of the thyroid gland in preterm infants born between 24 and 32 weeks of gestation inborn or admitted to the unit within 14 days from birth and compare it with the results of TSH and FT4 blood concentration. Besides, the objective of the study is to determine values of thyroid hormones in premature infants born before 33 wk gestation to help neonatologist to interpreter the thyroid hormone results
The study aimed to compare the efficacy and safety of papillary thyroid microcarcinoma (PTMC) treated with microwave ablation(MWA) and surgery resection (SR), and to explore the tumor characteristics suitable for each treatment methods (such as with and without capsular invasion). The investigators organized 18 hospitals to participate in this multicenter study. Patients meeting following indications will be included in this study: 1. Biopsy pathology proved PTMC, but not high-risk subtype; 2. solitary mPTC, without US-detected gross extrathyroid extension; 3. no evidence of metastasis; 4 willing to participate in this study and perform regular follow-up. Patients themselves decide to receive MWA or SR for mPTC after medical consultation. Baseline characteristic including age, gender, thyroid function et al. will be collected. The treatment protocols of MWA and SR were according to the Chinese and international guidelines. The primary outcomes were the disease progression, including local tumor recurrence, lymph node metastasis, and distant metastasis. The secondary outcomes include thyroid function, complication rate, blood loss et al. Investigators will follow up enrolled patients and collect and upload data according to the trial. Treatment outcomes of tumor with and without US-detected capsular invasion was analyzes as subgroups.
The purpose of this study is to determine Safety and Efficacy of Radioactive Iodine (RAI) Treatment of Metastatic and Advanced Differentiated Thyroid Cancers by Pretreatment With Apatinib for the Neoadjuvant Regimen
This phase II trial studies how well lenvatinib and pembrolizumab work in treating patients with anaplastic thyroid cancer that is stage IVB and has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable), or stage IVC that has spread to other places in the body (metastatic). Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Given lenvatinib and pembrolizumab may work better than giving either one alone in treating stage IVB or C anaplastic thyroid cancer.
Natural thyroid function changes during pregnancy. In up to tens of percent of pregnant women, these changes can lead to pathological fluctuations in hormone and antibody production. Although the effects on pregnancy and child development are well described, none has determined their influence on mother's emotional well-being and the quality of life. At present, universal thyroid screening in pregnancy in the Czech Republic is not covered by health insurance. The aim of the project is to change this situation by providing quality of life estimate for the cost-effectiveness model. This is a project of three specialized institutions aimed at mapping various aspects of the quality of life of pregnant women and describing the impact of thyroid disease on their lives. The project is a parallel study to a larger project Early screening for thyreopathy in pregnancy (CZ.03.2.63/0.0/0.0/15_039/0009643) supported by the European Fund Operational Programme Employment through the National screening centre. The data will be collected through online questionnaire from women enrolled in the Early screening for thyreopathy in pregnancy (CZ.03.2.63/0.0/0.0/15_039/0009643) who were screened for TSH, TPOAb and FT4.
Bone radioiodine (RAI) uptake without structural abnormality in thyroid cancer (TC) patients may be related to false positive or to microscopic foci of metastatic tissue. In such cases, outcome is reported to be excellent. Indeed, Robenshtok et al. reported a serie of patients with RAI-avid bone metastases of TC without structural abnormality on imaging studies who have more favorable long-term prognosis than those harbouring structurally visible bone metastases and do not undergo skeletal-related complications. The investigators report the case of Mrs D., who had been operated for a pathologic tumor stage 3: pT3(m) poorly differentiated TC at the age of 43. The first post-therapeutic whole body scan revealed 3 foci of bone uptake (right clavicle, L2, L3). The elevated level of thyroglobulin (157ng/mL) favoured the hypothesis of bone metastases despite the absence of any structural lesion on CT and MRI. She received 7 courses of radioiodine therapy. The right clavicle RAI uptake persisted, and subsequent CT disclosed an osteolytic lesion which was treated by radiofrequency and external beam radiation. Twenty-five years after the diagnosis, she has a persistent morphological disease with a 30x8mm progressive lesion on the right clavicle, for which surgery is planned. The aim of the present study is to describe the natural history and evolution of radioiodine avid bone metastases from thyroid cancer without structural abnormalities and to identify prognosis factors.
