Filter by:To conduct a retrospective multicenter cohort study to define benchmark values for best achievable outcomes following transsphenoidal resection of pituitary adenomas.
(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.
Oxytocin (OT) is a hypothalamic peptide that enters the peripheral circulation via the posterior pituitary gland. OT plays a key role in regulating appetite, psychopathology, prosocial behavior and sexual function. Hypopituitarism is associated with increased obesity, increased psychopathology, sexual and prosocial dysfunction despite appropriate hormone replacement. A few studies suggest the existence of a possible OT deficient state in hypopituitarism. In animal models, corticorelin hormone (CRH) has shown to increase OT release. This study is designed to evaluate oxytocin values after administration of CRH in adults (healthy volunteers and patients with hypopituitarism). The investigators hypothesize that OT response will be blunted following CRH in patients with hypopituitarism compared to healthy controls.

A few studies suggest the existence of a possible OT deficient state in hypopituitarism. In animal models, glucagon-like peptide 1 (GLP1) has shown to increase OT release. This study is designed to evaluate OT values after administration of GLP1 in adults (healthy volunteers and patients with hypopituitarism). The investigators hypothesize that OT response will be blunted following GLP1 receptor agonist (GLP1-RA) in patients with hypopituitarism compared to healthy controls.
The primary aim of the study is to describe the effect of a single oral dose of semaglutide 7 mg on growth hormone secretion.
Prospective and randomized evaluate efficiency and safety of different treatment strategies for hypothalamus-invading pituitary adenomas (HIPA)
This trial is to determine the effect of Tranexamic Acid (TXA) on blood loss during endoscopic pituitary surgery. The hypothesis of this study is that TXA will reduce blood loss during surgery compared to a placebo. To answer this hypothesis, the investigators are conducting a randomized controlled trial in which half of participants will receive TXA and half will receive placebo (saline) in a double blind fashion.
This study evaluates the structural parameters, by spectral domain optical coherence tomography (OCT), retinal vessel density, using OCT angiography, and visual acuity in patients that received endoscopic endonasal approach for the removal of an intra-suprasellar pituitary adenoma compressing the optic nerve.
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.
The aim of the project is to compare the effect of different extent of resection of the posterior part of the septum on the postoperative nasal functions.
