Filter by:To assess the benefit of using an additional nerve block during minimally invasive pituitary surgery, to improve pain management after surgery. The medication (Bupivacaine) or a placebo (saline) will be injected during surgery and patients will be asked about their level of pain at multiple time points in the first 24 hours following surgery. The aim is to improve patient outcomes and reduce the need for pain medication after surgery.
The primary purpose of this study is to compare the safety of routine telephone assessment versus in-person assessment during a two-year period for patients with non-functioning pituitary adenomas. Secondly, to compare the quality of pituitary care in persons having biochemical assessment once versus twice a year. Thirdly, to assess the rationale of repeated assessment of pituitary function and imaging in patients with small pituitary tumors (microadenomas).
In multiple previous studies that have explored the use of dexmedetomidine in transsphenoidal tumor resection surgery, dexmedetomidine showed many beneficial effects like reducing the requirement of analgesics and anesthetics, improving hemodynamic stability and decreasing the emergence time, extubation time and visual analog scale at emergence. Therefore, the investigators hypothesized that dexmedetomidine would decrease neuroendocrine stress response and improve the quality of postoperative recovery.
(1) Objective to establish an evaluation system for predicting the risk of epistaxis after endoscopic transsphenoidal pituitary surgery（ 2) Objective to determine the risk factors of epistaxis after endoscopic transsphenoidal pituitary adenoma surgery. Referring to domestic and foreign literature, combined with experts' opinions, the related risk factors that may cause postoperative nosebleed of pituitary adenoma are: 22 patients and surgical factors. 3) Objective to establish a risk prediction model of epistaxis after endoscopic transsphenoidal pituitary tumor resection. According to the occurrence of epistaxis, the patients in the modeling group were divided into epistaxis group and non epistaxis group. The risk factors of epistaxis were taken as the independent variable, and the occurrence of epistaxis was taken as the dependent variable. The variables with statistical significance in univariate analysis were included in the multivariate logistic regression model, and the risk prediction model of epistaxis after pituitary tumor resection was established by back LR method.(4) Objective to verify the risk prediction model of endoscopic transsphenoidal pituitary adenoma epistaxis. The validation model is used to validate the prediction model, and the Hosmer-Lemeshow degree is used to match the model. The area under the receiver operating characteristic curve (ROC) was used to evaluate the validity of the model.(5) Application of risk prediction model.
Prospective and randomized evaluate efficiency and safety of different treatment strategies for hypothalamus-invading pituitary adenomas (HIPA)
Perioperative pain relief during endoscopic transsphenoidal pituitary surgery is generally treated with opioids either morphine sulfate or fentanyl. This study will compare the traditional method of intravenous fentanyl to the bilateral infraorbital nerve block in adult patients scheduled for pituitary surgery by the transsphenoidal approach.
Background: Cushing s disease is caused by a pituitary gland tumor. Patients with Cushing s disease suffer obesity, diabetes, osteoporosis, weakness, and hypertension. The cure is surgery to remove the pituitary tumor. Currently, MRI is the best way to find these tumors. But not all tumors can be seen with an MRI. Researchers hope giving the hormone CRH before a PET scan can help make these tumors more visible. Objective: To test whether giving CRH before a PET scan will help find pituitary gland tumors that might be causing Cushing s disease. Eligibility: People ages 8 and older with Cushing s disease that is caused by a pituitary gland tumor that cannot be reliably seen on MRI Design: Participants will be screened with their medical history, a physical exam, an MRI, and blood tests. Participants will have at least one hospital visit. During their time in the hospital, they will have a physical exam and a neurological exam. They will have a PET scan of the brain. A thin plastic tube will be inserted into an arm vein. A small amount of radioactive sugar and CRH will be injected through the tube. Participants will lie in a darkened room for about an hour and be asked to urinate. Then they will lie inside the scanner for about 40 minutes. After the scan, they will be asked to urinate every 2-3 hours for the rest of the day. Blood will be drawn through a needle in the arm. Participants will have surgery to remove their tumor within 3 months after the scan. Participants will then continue regular follow-up in the clinic.
Headache is a very common main complaint of patients with GH pituitary tumor, which has seriously affected the normal work and life of patients. Although the current surgery and drugs have a certain effect on patients with headache, the overall effect is not satisfied. However, the use of COX-2 inhibitors, non-steroidal anti-inflammatory drugs and other analgesics are only effective for some patients with headaches, and long-term use has adverse reactions. Therefore, it is necessary to seek new treatments for postoperative headaches in patients with GH pituitary tumors. Transcranial magnetic stimulation (TMS) modulates the excitability of the underlying cerebral cortex by applying a rapidly changing magnetic field on the surface of the scalp. It is a relatively simple and safe method. It is currently approved for treating depression, migraine, obsessive-compulsive disorder, and Alzheimer's disease. Several small clinical studies have proven that rTMS can be used to prevent and treat Headache. Therefore, this study aims to observe the efficacy and safety of TMS in the treatment of postoperative headache in patients with GH pituitary tumors.
5-Aminolevulinic Acid (5-ALA) was approved by the FDA as an intraoperative optical imaging agent in patients with suspected high-grade gliomas (HGGs) in 2017. The investigators plan to administer 5-ALA to patients with pituitary tumors to demonstrate whether it can be used as an intraoperative optical imaging agent for this pathology. Overall, this pilot study will afford the overall opportunity to improve surgical management and advancement of the science of neurological and neuroendocrine disease.
This is a randomized, double-blind, placebo-controlled study to assess the safety, tolerability, efficacy, PK, and PD of the chimeric dopamine-somatostatin receptor agonist, TBR-760, in adult patients with NFPA over 52 weeks.
