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.
This is an observational, longitudinal, single-center study. The study is divided in two phases: - FIRST PHASE (retrospective): registration of all patients affected by pituitary disorders followed at the Unit of Endocrinology of Azienda Ospedaliero-Universitaria of Modena - SECOND PHASE (prospective): enrollment of all patients affected by pituitary disorders who attend the Unit of Endocrinology of the Azienda Ospedaliero-Universitaria of Modena. An anonymized database will be created to collect the data of the patients. In particular, the data collected for each patient will include: personal data, data relating to pituitary pathology, symptoms at diagnosis, physical examination, radiological imaging, visual field data, data on surgical intervention, data on histological examination, biohumoral examinations, hormone tests, densitometric data, data on replacement therapies, medical therapies or other pharmacological therapies, data on comorbidities.
The purpose of this study to age-related differences to the response of a combined pituitary stimulation test with TRH, LHRH and ACTH.
Context. The relevance of hyponatremia has been acknowledged by guidelines from the United States of America (2013) and Europe (2014). However, treatment recommendations differ due to limited evidence. Objective. In hyponatremia following pituitary surgery - caused by the syndrome of inappropriate antidiuretic hormone (SIADH) secretion - the investigators compared fluid restriction with the pharmacological increase of water excretion by blocking the vasopressin 2 receptors with tolvaptan at a low and moderate dose. Design. Prospective observational study. Setting. Neurosurgical Department of a University hospital with more 200 pituitary procedures per year. Patients. Participants undergoing surgery for sellar lesions and developing a serum sodium below 135 mmol/L. The diagnosis of SIADH was established by eu- or hypervolemia (daily measurement of body weight and fluid balance daily), an inappropriately concentrated urine (specific gravity) and exclusion of a cortico- and thyreotropic insufficiency. Intervention. Participants were treated with fluid restriction (n=38) or tolvaptan at 3.75 (n=38) or 7.5 mg (n=48) orally. Main Outcome Measures. Treatment efficacy was assessed by the duration of hyponatremia, sodium nadir and length of hospitalization. Safety was established by an increment serum sodium below 10 mmol/L per day and exclusion of side effects.
The purpose of this study is to determine if nivolumab and ipilimumab are effective treatment for people with pituitary tumors have gotten worse after surgery and radiation.
Hyponatremia is defined as sodium below the normal range of 135-145. Symptomatically, it can cause patients to experience a wide range of symptoms including lethargy, headache, nausea, vomiting and in severe cases coma and even death. The goal of this study is to prospectively compare two approaches to the postoperative fluid management of patients undergoing transsphenoidal resection of a pituitary tumor or cyst to decrease the occurrence of postoperative delayed hyponatremia. One group will be placed on moderate fluid restriction and the other group will be placed on ad lib fluid intake.
This study is designed to measure forces applied using standard surgical instruments at the skull base during resection of skull base lesions. This data will be useful for optimizing an active canula robot for assisting in skull base surgery. We hypothesize that through measurement of forces generated during routine endoscopic skull base surgery we will be able to optimize the canulas of an active canula robot for skull base surgery.
