Filter by:The images of patients with Pituitary adenoma were collected and analyzed based on the methods of radiomics.
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 pituitary gland is a small pea-sized gland that produces a variety of important hormones. Some children are born with a deficient production of two or more pituitary hormones. This rare and potentially severe disease is called congenital combined pituitary hormone deficiency (cCPHD). cCPHD can cause many different symptoms, some of which appear shortly after birth and others later in childhood. Symptoms that appear shortly after birth are e.g., development of very low blood sugar, disturbances in the salt balance, and severe dehydration, whereas symptoms that appear later in life are short stature, missing pubertal development, fatigue, and sensitiveness to cold. Fortunately, it is possible to replace the missing hormones. Currently, it is unknown how common cCPHD is. Therefore, the investigators wish to examine 1) how many children are diagnosed with cCPHD before the age of 18 years, 2) how many children are diagnosed with cCPHD at age <1 year, 1-8 years, 9-17 years, and 3) the patients' hormone deficiency characteristics and brain MRI scans. The investigators will identify the patients by searching for diagnosis codes used for pituitary disease and pituitary malformations in the Danish National Patient Registry and locally at the four hospitals approved for the treatment of cCPHD in children. Through the searches, the investigators expect to identify approximately 1500 patients. The investigators will then review the hospital files of all identified patients to exclude patients with only one hormone deficiency and patients with an acquired cause of the disease. The investigators aim to include all cCPHD patients in Denmark born in the period 1996 and 2020.
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.
To determine the outcomes of patients with different pituitary disorders whether they are managed medically, surgically or expectantly.
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.
Damage to the pituitary gland is a frequently overlooked but potentially important complication of traumatic brain injury (TBI). Disorders of the pituitary gland can cause dysfunction of the thyroid, adrenals, ovaries and testes. These disorders may occur immediately or several months after TBI, may delay recovery and may have a significant negative impact on quality of life. TBI is the leading cause of disability and major permanent functional impairment among adults under 45 years of age. Hormonal deficits may contribute to common symptoms experienced by TBI survivors such as fatigue, poor concentration, depression and low exercise capacity. However, the association between hormonal deficits and disability remains uncertain. The primary objective of this pilot study is to assess the feasibility of a larger study that will evaluate the impact of pituitary disorders on neurological disability and functional recovery. The results of this study will provide key findings in the impact of pituitary disorders following TBI, which is a mandatory step prior testing the effect of hormonal replacement therapy in this population in costly clinical trials. If no relationship between pituitary disorders and disability is observed, the investigators' findings will prevent unnecessary, time-consuming and costly hormonal screening and will discourage potentially harmful hormonal therapy.
Context: Pituitary adenoma is generally indolent, but an aggressive subtype called atypical adenoma has uncertain prognosis, and an unclear relationship between prognosis and morphology. Objective: This study investigated the prognostic factors of this tumor. Design: Retrospective analysis. Setting: University and associated hospitals.
The purpose of this study is to study the effects of aging and estrogen on the brain. Specifically, this study will examine how the hypothalamus signals the pituitary gland to secrete reproductive hormones and how that changes with aging.
