NCT07099404
Assess the uptake of rubidium-82 in parathyroid adenomas.
NCT07043010
Primary hyperparathyroidism is usually cured by removing the single over-active parathyroid adenoma. During surgery, however, surgeons often see a thin rim of normal parathyroid tissue that still "glows" under a near-infrared parathyroid tissue sensor (PTS). It is unclear whether keeping this tissue in place helps preserve hormone function or whether it leaves behind cells that could become over-active again. The WHITE CAP study will compare two common surgical choices: Preservation strategy - the surgeon removes only the adenoma and leaves the glowing rim of normal tissue untouched. En-bloc strategy - the surgeon removes the adenoma together with the glowing rim; if too little parathyroid tissue remains, a small fragment is transplanted into the forearm muscle. About 120 adult patients who have a single parathyroid adenoma will be randomly assigned (like tossing a coin) to one of the two strategies. All operations will use the same FDA-cleared PTS camera that shows the glands in real time without dye or radiation. The main question is whether preserving the normal rim lowers the rate of temporary low blood-calcium (numbness, tingling) during the first two days after surgery. The study will also check long-term results-blood calcium and parathyroid hormone (PTH) levels, symptoms, and any return of the disease-over two years. The PTS imaging itself is painless and adds only a few minutes to the operation. Risks are the same as for standard parathyroid surgery, and participants can withdraw at any time without affecting their usual care.
NCT06913296
Identifying the parathyroids is compulsory for success of parathyroidectomy for parathyroid adenoma. Near-infrared autofluorescence devices have been proposed as useful intraoperative tools for the identification of parathyroid glands. The aim of the present study is to evaluate the correlation of PTeye autofluorescence device with biochemical data of parathyroid adenoma patients.
NCT04085913
The question proposed by this study, is one of patient outcomes. Does intraoperative injection of Exparel decrease postoperative use of opioid pain medications in patients undergoing thyroid and parathyroid surgery? The trial seeks to assess the effect that Exparel has on postoperative pain control.
NCT03027557
The only known cure for primary hyperparathyroidism is surgical removal of one or more parathyroid glands. Some patients however, do not fulfill criteria for surgery or do not want to undergo a procedure due to fear of the associated risks. Therefore a medical alternative is warranted. This study aims to evaluate the effects of Denosumab alone, and in combination with Cinacalcet, as a medical treatment for patients suffering from primary hyperparathyroidism, with mild osteoporosis. To the best of our knowledge no previously reported randomized controlled trial has investigated the use of denosumab in primary hyperparathyroidism. 60 patients will be enrolled in three different treatment-groups: 20 receiving both Denosumab and Cinacalcet, 20 Denosumab and placebo and 20 placebo and placebo. Patients included do not meet the criteria for, or have no wish for a surgical procedure. By combining the two drugs, this study could possibly contribute to the discovery of a realistic medical alternative to surgery. It is expected that the therapy will be able to both control s-calcium and s-intact parathyroid hormone (iPTH), and simultaneously enhance bone-structure. The therapy thus has the potential of preventing fractures and possibly other long-term effects of primary hyperparathyroidism such as formation of kidney stones, and coronary calcification. Another objective of this project is to investigate whether the combined therapy can facilitate an actual reset of the Calcium-sensing receptor, and thereby de facto cure the disease.
NCT03469310
This research is being done to better understand and test if the investigators can minimize narcotic medication for controlling pain after thyroid or parathyroid surgery. This research will be performed at Doctors Hospital At Renaissance in the investigators clinic and the perioperative area. Participants will be randomly chosen to receive one of two options for pain management that the investigators are already using in the care of patients after surgery. One option includes a narcotic medication and one option includes a non-narcotic and a narcotic as needed. Participants will be asked to complete a form about the level of pain and how much pain medication was needed after surgery in the hospital and while at home. Participants will not have to do any additional visits to participate in this study. The investigators will obtain the research materials at the same time as the usual care visits around the participants' surgery.
NCT04570033
We assessed sensitivity of 18F-FCH PET/CT in preoperative localisation of hyperfunctioning parathyroid tissue in patients with primary hyperparathyroidism (PHPT).
