Filter by:This study aims to investigate the analgesic efficacy of Intermediate Cervical Plexus Block combined with GA using two bupivacaine concentrations in patients undergoing neck surgeries (total thyroidectomy or total laryngectomy)
The purpose of this study to learn more about the use of redifferentiating medications as a standard treatment for radioactive iodine/RAI-refractory thyroid cancer. This study is a registry study.
The purpose of this clinical trial is to investigate the accuracy of applying three-dimensional ultrasound on thyroid gland patients when determining a gland volume. The method will be compared to conventional b-mode ultrasound where three axis measurements (length, width, and depth) are evaluated in the ellipsoid model. The three dimensional (3D) method is utilizing optical tracking connected to the ultrasound image to form cross-sectional imaging. Patients enrolled in the study are set for complete thyroidectomies enabling a true volume of the gland by water displacement after excision. The aim is to find if this 3D method is more accurate in volume estimation than the ellipsoid model.
An unanticipated difficult laryngoscopy is associated with serious airway-related complications. The investigators developed a deep learning-based model that predicts a difficult laryngoscopy (Cormack-Lehane grade 3-4) from a cervical spine lateral X-ray using data from 14,135 patients undergoing thyroid surgery. This model showed excellent predictive performance, which was higher than that of other deep learning architectures. In this study, the investigators prospectively validate the model for predicting a difficult laryngoscopy and compare predictive power with clinical airway evaluation.
This is an open label, single center, phase 2 trial of adjuvant pembrolizumab after external beam radiation to the primary tumor in patients with stage IVB (disease localized to the neck) ATC. This drug trial will estimate the median progression-free survival (PFS) (from the start of adjuvant pembrolizumab until locoregional progression, development of distant metastatic disease, or death) in stage IVB ATC patients with gross disease, treated with external beam radiation (+/- concomitant chemotherapy) followed by adjuvant pembrolizumab. Patients will be patients enrolled from cohort 1 and 2 (cohort 1: ≥51 Gy; cohort 2: ≤50 Gy).
The purpose of this study is to explore whether percutaneous laser ablation (PLA) is a safe and effective alternative to removing papillary thyroid microcarcinoma (PTMC) with surgery.
The purpose of this research study is to see if the amount of vitamin D in ones blood makes it more or less likely to develop thyroid gland toxicity when being treated with immunotherapy that blocks the activity of proteins called programed death-1(PD-1) or programmed death ligand-1 (PD-L1). Immunotherapy is treatment that makes changes to the immune system to try to fight cancer. Immunotherapy treatments that block the activity of important parts of the immune system called PD-1 and PD-L1 are used to standardly treat many different types of cancer and can cause thyroid toxicity in certain people. In this study the treatment for your cancer is not research treatment but standard of care determined by your oncologist. Blood will be drawn before starting treatment to determine the amount of Vitamin D and also to assess thyroid function. Also questionnaires will be completed before starting treatment and while on treatment to assess symptoms you are experiencing.
The medical information delivered to the patient before any surgery constitutes an essential and compulsory step during the initial management of the operated patient. There are different reasons for the quantity and quality of medical information retained by the patient. An internet platform with personalized and secure access has been developed. This platform contains, among other things, an explanatory video of thyroid surgery and allows the patient to have access to information on surgical management at any time. The investigators believe that unlimited access for the duration of the study to this platform could reduce the preoperative anxiety level of patients.
In the outpatient clinic based population setting, the investigators want to reappraise the accuracy of the new model of multi-factorial ultrasound diagnosis with the conventional fine-needle aspiration cytology.
Full intellectual capabilities are achieved only if crucial nutrients are present during development. Iodine deficiency is the most common cause of preventable brain harm in infants. Because of its critical need during pregnancy, several countries implemented programs of iodine supplementation in preconception and pregnancy. In 2013, the prevalence of iodine deficiency in Portugal has led health authorities to issue a recommendation for iodine supplementation. This study aims to evaluate the impact of iodine supplementation on maternal and fetal iodine status and thyroid function, obstetric outcomes, quality of breast milk and child psychomotor development. It also intends to evaluate whether the time of iodine supplementation initiation influences all the above-mentioned parameters. The novelty and relevance of this study reside on the number of women/child and on the extent of health parameters that will be evaluated. The information collected will contribute to the detailed characterization of thyroid hormone homeostasis throughout pregnancy and its relationship with iodine supplementation (including time of initiation). The data will provide evidence on whether this iodine supplementation strategy impacted on iodine sufficiency of the mother and the newborns, or if it needs re-evaluation.
