Filter by:The purpose of this research study is to determine the utility of educational materials designed to inform patients of their pituitary condition, in an effort to assist the patients, families, and staff deal with pituitary tumours and related conditions in the best way possible. We have developed a website, informational videos, and a brochure for pituitary tumour patients and their families. The primary outcome measures will be 1) the level of knowledge that patients have of their condition before and after reviewing the materials provided; and 2) ease of use and user satisfaction of the materials. We hypothesize that our informative multimedia educational package will not only improve the health literacy and self-efficacy of patients and their families, but will also improve quality of care.
There are no available medical treatment options for patients with non-functioning pituitary adenomas (NFPA) or with resistant prolactinomas to dopamine agonists (DA) who are not cured by surgery. The study of the receptors by quantitative mRNA expression levels and immunohistochemistry analysis might end with a better understanding of these tumors. Besides that, it will be assessed the in vitro and in vivo responses to pasireotide (for NFPA and prolactinomas) and cabergoline (for NFPA). These responses will be compared with the receptor expressions which may be a tool as a predicting element of the response to these compounds.
This project is the first comprehensive prospective study of clinically non-functioning pituitary adenomas (CNFAs). Two groups of subjects will be studied: Group I will consist of 100 patients with clinically non-functioning (CNF) pituitary lesions who are asymptomatic and do not require surgery; Group II will consist of 250 patients who have pituitary lesions that are symptomatic and require surgery. Patients will be followed with a series of endocrine laboratory testing, physical examinations, testing of quality of life and neurocognitive function before and serially over time either during non-surgical management or after surgery and in some patients before and after radiotherapy (RT). Data on pituitary magnetic resonance imaging (MRI) studies and visual field testing being done over time during follow up as part of clinical care will be collected.
Pituitary adenomas is a very common disease, but the cause and genetics hasn't been identified. The investigators are going to use genome-wide association study to identify genes that may be related to pituitary adenomas.
Pituitary adenomas can cause compression of optic nerves and chiasm, which will lead to damage of vision. This study aims to evaluate the predictive factors for recovery of vision in patients with pituitary adenomas following trans-sphenoidal surgery.
The major purpose of this study is to evaluate the changes of multiple organs in patients with growth hormone-secreting pituitary tumors before and after surgery. Plasma, DNA samples and pituitary tumor tissues will be kept for further analysis.
Characterization of receptors present in non-functioning pituitary macroadenomas by Reverse Transcriptase- Polymerase Chain Reaction (RT-PCR) would assist with targeted medical therapy based on the information obtained by immunohistochemistry and RT-PCR.
The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity in patients harboring pituitary mass lesions of all types.
The purpose of the study is to determine genetic links among blood-relatives and between spouses of patients with pituitary tumors.
The purpose of this study is to determine if topical steroids treatment for different skin diseases suppress the adrenal cortisol production.
