Filter by:The effectiveness of antimicrobial prophylaxis (AMP) for prevention of surgical site infection (SSI) following thyroid and parathyroid surgery remains uncertain. Present prospective randomized control study (Ito-RCT1) assessed the effectiveness of AMP in clean neck surgery associated with thyroid and parathyroid disease.
This study is being conducted to identify altered genetic factors that may exist and influence endocrine cancers in unrelated MEN1 families with different cancers. A grading system will be developed for endocrine cancers, including pancreatic cancers, thymus gland cancers, parathyroid disease and MEN1 syndrome as low-risk and high-risk to improve screening and timing of surgery.
It is difficulty for the treatment of secondary hyperparathyroidism in the chronic kidney disease (CKD) patients who had not succeeded medical therapy and could not get parathyroidectomy. The investigators suppose that ultrasonic ablation may be a valuable alternative treatment that help control secondary hyperparathyroidism in CKD patients presenting with enlarged parathyroid gland(s) visible at ultrasonography.
Hyperparathyroidism (excessive production of parathyroid hormone (PTH) usually caused by a small growth called an adenoma in the parathyroid glands) is an increasingly significant medical and public health condition. Surgery is the only effective management for primary hyperparathyroidism. However; it is sometimes difficult to pinpoint the adenoma, in part because current methods of imaging often fail to identify the parathyroid adenoma in as many as 30% of patients. In reoperative parathyroidectomy for persistent or recurrent hyperparathyroidism, localization plays an even greater role. Unfortunately current multiple imaging methods fail to localize 10-15% these of tumors. SPECT/CT with the radiotracer 99mTc sestamibi has become the standard method for pinpointing the tumor. This, however, is a challenge because the parathyroid glands usually are located close to the thyroid and the radiotracer 99mTc sestamibi concentrates both in thyroid and parathyroid tissue. Hence there is a need for a tracer/imaging tool that concentrates in the parathyroid but not in the thyroid. A more sensitive and specific radiotracer/tracking agent would markedly improve the investigators ability to identify parathyroid tumors preoperatively, and thus offer more patients a minimally invasive parathyroidectomy. anti-3-[18F]FACBC is an amino acid based PET radiotracer which has shown utility in detecting a variety of tumors. In cell culture experiments, anti-3-[18F]FACBC has shown uptake in parathyroid cells greater than thyroid cells. Therefore, the investigators think that this radiotracer may be able to help us identify parathyroid adenomas better than 99mTc sestamibi. The primary aim of this study is to determine if anti-3-[18F]FACBC PET-CT demonstrates uptake within parathyroid adenomas. 12 patients with a diagnosis of primary hyperparathyroidism will undergo PET-CT using anti-3-[18F]FACBC in addition to the standard 99mTc sestamibi scanning and other imaging as clinically appropriate such as ultrasound, MRI, and/or contrast enhanced CT scanning. Since all these patients undergo surgery routinely, the investigators will then compare findings at surgery to those of the anti-3-[18F]FACBC PET-CT to determine if this radiotracer is worthy of further study in a more comprehensive experiment.
The purpose of this study is to analyze the findings of 30 surgeons and 30 nuclear radiologists of 61 individual thyroid scans. The goal is to determine if surgeons are more prone to making a definitive diagnosis based on a given scan than a nuclear radiologist. Accuracy of localization of the two groups will be analyzed. A secure website has been designed to which the physician will be able to login and view and rate the quality of each image and make a localizing diagnosis. Once they are finished, they will not be able to make any more changes, and their responses will be compared to the responses of their colleagues. The results will be analyzed to find if there is a significant variation in the ratings between the surgeons and the nuclear radiologists as to the quality, location, and number of parathyroid glands, if any, on the scans.
The goal of this study is to help better determine the complication rates for endocrine surgery across the nation for both benign and malignant disease. It is our hypothesis that the complication rates are low overall and that malignant disease results in a higher complication rate than benign disease. This study will do a database review from all University HealthSystem Consortium (UHC).
The intent for this study is to do a retrospective chart review of all patients who have undergone minimally invasive parathyroidectomy for primary hyperthyroidism. All data collected will be recorded under assigned identification numbers that will have no association with medical record or hospital numbers. Identifying characteristics will include age and sex. Anonymity will be upheld. The patient/family will not be contacted directly. All information will be obtained from the medical chart. Demographics, location, preoperative PTH levels and intraoperative Ex-Vivo gamma counts, co-morbid conditions, and the outcome based on the hospital notes will be obtained from patients' charts and will be transferred to a secure database. It is our hypothesis that there is a linear relationship between immediate preoperative parathyroid hormone (PTH) levels and Ex-Vivo gamma counts and the aim of this study is to better describe this relationship.
Postoperative pain and nausea may diminish a patient`s wellbeing, and may also delay rehabilitation, as well as increase the total cost of care and treatment. Opioids are effective drugs for treatment of pain, but with the disadvantage of side effects such as somnolence and nausea. The benefits of various types of non-opioid analgesic in reducing patients` postoperative need for opioids have been well-documented. One non-opioid prophylaxis documented for various surgery is short-term treatment with corticosteroids. The optimal dose of corticosteroids for peroperative nausea and pain prophylaxis is not well-documented. In our study we will attempt to determine whether the aforementioned benefits of corticosteroids are valid for a group of patients undergoing thyroid surgery. Hypothesis: Single-dose treatment with dexamethasone provides a better analgesic effect and/or reduced use of opioids than placebo in patients undergoing elective throid surgery. Higher dose of dexamethasone provide better and/or longer-lasting analgesic effects without influencing the side effect profile.
