Filter by:The purpose of this research is to find out if SSKI (Potassium Iodide) reduces vascularity (the number and concentration of blood vessels) and improves how well patients do after surgery for removal of their whole thyroid gland in Graves' disease (an autoimmune disease that is a common cause of hyperthyroidism).
Currently, both the American Thyroid Association and the European Thyroid Association recommend the use of Lugol Solution (LS) in the preparation of patients undergoing thyroidectomy for Graves' disease (GD), but their recommendations are based on a low level of evidence. This means that its use is not generalized among the different endocrine surgery units. Methods: Study population: 270 patients (135 patients in each arms) undergoing total thyroidectomy (TT) due to GD in Spanish hospitals, which perform a minimum of 100 thyroidectomies a year, at least 10 of them for GD. Variables: Preoperative variables - Demographic variables: birthdate, gender and ethnicity. - Drugs allergies. Allergy to iodine. - Personal history and usual treatment. - Aspects related to the GD: date of diagnosis, use of AT drugs and/or radioiodine, existence of ophthalmopathy, existence of cervical compression symptoms and indication of surgery. - Physical exploration: body mass index, pulse at rest and blood pressure and cervical palpation. - Laboratory tests: hematocrit, leukocytes, neutrophils, platelets, international normalized ratio(INR), creatinine, potassium, total calcium, albumin, total proteins, parathormone (PTH), 25-hydroxide-vitamin D, free T4 and / or free T3, TSH, thyroid stimulating immunoglobulin (TSI). - Classification of the anesthetic risk of ASA. - Cervical ultrasound: existence of thyroid nodules and volume of the thyroid. - Mobility of the vocal cords evaluated by laryngoscopy. - Compliance with assigned treatment: the patient assigned to the LS arm must have consumed at least 80% of the total dose indicated. Intraoperative variables - Surgical time. - Antibiotic prophylaxis - Intraoperative hemorrhage. - Thyroidectomy Difficulty Scale. - Loss of electromyographic signal during neural intraoperative monitorization. - Accidental parathyroidectomy. - Section or obvious lesion of the recurrent laryngeal nerve. - Trachea or esophagus perforation. - Weight of the gland. - Electrosurgical hemostasis system used during the intervention. - Maneuvers used to check hemostasis. - Hemostats used during the intervention. - Use of drainage. - Definitive surgical technique: TT, unilateral or bilateral subtotal thyroidectomy or hemithyroidectomy. Postoperative variables - Early complications: hypoparathyroidism, paralysis of the recurrent laryngeal nerve, postoperative hematoma, surgical site infection or death. - Debit for surgical drains. - Postoperative hospital long of stay. - Anatomopathological variables: histological diagnosis compatible with GD and existence of parathyroid glands in the surgical specimen. - Long-term complications: hypocalcemia and/or permanent vocal cord paralysis longer than 6 months
This study aims to develop a standardized universal imaging protocol for ICG-guided fluorescent total thyroidectomy, including quantitative evaluations of the fluorescent signal. Therefore, patients will undergo thyroid surgery (total thyroidectomy) with the use of ICG fluorescence.
This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.
Graves' orbitopathy (GO) is a characterized by orbital soft tissue inflammation and oedema associated with glycosaminoglycan deposition and fibrosis. The most frequent cause is Graves' disease. The classification is comprised based on the severity of orbital changes ranging from mild, moderate-to-severe GO and sight-threatening GO, which includes dysthyroid optic neuropathy (DON). Intravenous methylprednisolone (IVMP) pulse therapy is the first-line treatment in the active-phase of moderate-to-severe GO and DON. This therapy is more effective and better tolerated than oral glucocorticoids (GCs). The current recommendation of the European Group of Graves' Orbitopathy (EUGOGO) is that cumulative doses of IVMP should not exceed 8.0g in each treatment course, and pulses should not be given on consecutive or alternate days, except in the case of DON. According to EUGOGO recommendations patients with moderate-to-severe GO are treated with IVMP cumulative dose 4.5g during a 12-week period (for the first 6 weeks 0.5g IVMP per week, for the next 6 weeks 0.25g IVMP per week). According to EUGOGO recommendations patients with DON should receive 3.0g IVMP (1.0g/day for 3 consecutive days) as the basic treatment. This limitation in doses are due to the necessity of the prevention of severe side effects that are rare but may be fatal. One of the most severe adverse events is acute liver injury (ALI), in some cases irreversible and/or fatal. The estimated morbidity and mortality of ALI was found to be 1-4 % and 0.01-0.3%, respectively. Since 2000, there were 5 reported fatal cases. Mechanisms causing an IVMP-induced ALI remains incompletely elucidated. There are some possible hypotheses that may explain the occurrence of ALI. Firstly, GCs can lead to reactivation of autoimmune hepatitis: an immune "rebound phenomenon" following GCs withdrawal. The second mechanism of ALI is reactivation of viral hepatitis. Finally, there is well known direct toxic effect of GCs on hepatocytes, probably dose-dependent. This study was performed to evaluate the influence of two different, routinely used schemes of therapy with IVMP in patients with moderate-to-severe GO (first scheme) and DON (second scheme) on biochemical liver parameters. Patients included into the study were treated according to EUGOGO recommendations with routine doses of IVMP and routine scheme of administration for moderate-to-severe GO and DON. No additional treatment was performed during the study protocol.
Hypertension is common side effect of Cushing Syndrome (CS): in patients with endogenous CS and those treated with glucocorticosteroids (GCs). The impact of the intravenous GCs therapy on blood pressure (BP) remains unclear. According to the European Group On Graves' Orbitopathy (EUGOGO), patients with active, severely symptomatic and sight-threatening Graves' orbitopathy (GO) should be treated with high dose intravenous methylprednisolone (IVMP) pulses. There are, however, reports of fatal side effects that may be associated with this therapy (e.g.: pulmonary embolism, myocardial infarction, severe cerebrovascular events, acute liver damage and sudden death). For this reason, the cumulative dose of IVMP should not exceed 8 g within each treatment course, and pulses should not be given on consecutive or alternate days, except for the case of dysthyroid optic neuropathy. A consensus on the monitoring of patients during and after IVMP pulse administration is not yet established. What is more, there is lack of paper regarding pattern of blood pressure at various time points during and after ivGCs administration. Thus, the investigators decided to evaluate acute changes of N-terminal pro-brain natriuretic peptide (NT-proBNP) as a marker of hemodynamic stress and to monitor BP before, during and after IVMP pulse administration. All of patients were treated routinely according to EUGOGO recommendations with standard doses of methylprednisolone with standard recommended schedule. Inclusion criterion for the therapy was according to EUGOGO guidelines active, moderate-to-severe and active GO (12 pulses of IVMP 6x0.5g followed by 6x0.25g every week).
The alterations of coagulation and fibrinolysis parameters have been described in patients with endogenous Cushing's syndrome (CS) and those treated with glucocorticosteroids (GCs). The change in hemostatic process is associated with an increased risk of venous thromboembolic events (VTE) and pulmonary embolism (PE). Anticoagulation prophylaxis reduces thromboembolic complications in endogenous and exogenous hypercortisolism. The impact of the intravenous GCs therapy on hypercoagulability, however, remains unclear and perplexing. According to the European Group On Graves' Orbitopathy (EUGOGO), patients with active, severely symptomatic and sight-threatening Graves' orbitopathy (GO) should be treated with high dose intravenous methylprednisolone (IVMP) pulses. There are, however, reports of fatal side effects that may be associated with this therapy (e.g.: PE, myocardial infarction, severe cerebrovascular events, acute liver damage and sudden death). For this reason, the cumulative dose of IVMP should not exceed 8 g within each treatment course, and pulses should not be given on consecutive or alternate days, except for the case of dysthyroid optic neuropathy. Nevertheless, even smaller cumulative therapy may be associated with fatal cardiovascular complications. Hence the aim of our study was to evaluate the effects of IVMP therapy on hemostatic process in patients with GO. All of patients were treated according to EUGOGO recommendations with standard doses of methylprednisolone with standard recommended schedule. Inclusion criterion for the therapy was according to EUGOGO guidelines moderate-to-severe and active GO (12 pulses of IVMP 6x0.5g followed by 6x0.25g every week).
The study is aimed at assessing IGF-1R-Abs in patients with Graves' disease, with or without GO, compared with healthy subjects and patients with autoimmune thyroiditis in a cross-sectional investigation.
Graves' disease (GD) is an autoimmune thyroid disorder caused by stimulating auto-antibodies to the thyrotrophin (TSH) receptor on thyroid follicular cells. It is the most common cause of hyperthyroidism and approximately 3% of women and 0.5% of men develop GD in their lifetime. RAI has been shown to be a cost-effective and safe therapy in patients with GD but with some disadvantages. In addition, despite its proven efficacy and safety, many patients do not wish to undergo RAI because of radiation fear and prefer to either continue ATDs or have surgery. High-intensity focused ultrasound (HIFU) is a non-invasive procedure that involves the application of a high-energy focused beam for thermal tissue ablation within a targeted zone. Similar to the principle of RAI (i.e. using ionizing radiation to ablate thyroid parenchyma and cause GD remission), we postulated that the heat energy generated from HIFU could also be used to ablate the thyroid parenchyma and cause GD remission. The idea of using heat energy to ablate thyroid parenchyma minimally invasively was recently reported using radiofrequency ablation but to our knowledge, we are one of the first (if not the first) group to propose using HIFU energy to ablate thyroid parenchyma as a definitive treatment for relapsed GD. Having obtained ethical approval, a pilot study was conducted to examine the efficacy and safety of HIFU as a treatment for relapsed GD. In the pilot study, all patients underwent a safe and successful HIFU ablation for relapsed GD. Based on the results of the pilot study, we hypothesize that a single HIFU treatment to the thyroid gland may be as effective as our standard outpatient fixed-dose of RAI (370MBq) in causing remission of GD at 6-month. If our hypothesis turns out to be true, HIFU could become a treatment option for patients who are indicated for RAI but do not wish to have it because of one reason or another. HIFU appears to induce a faster disease remission and lessen the need of deferring pregnancy and radiation precautions because of the absence of radioactivity.
The study is a single-center prospective cohort study of clinical application of continuously monitored data by wearable activity trackers in the patients with thyrotoxicosis. The purpose of the study is to evaluate the association between parameters of pulse rate, activity, and sleep from wearable activity trackers and the thyrotoxic status along with the treatment.
