Filter by:Pleuropulmonary blastoma (PPB) is a rare malignant neoplasm of the lung presenting in early childhood. Type I PPB is a purely cystic lesion, Type II is a partially cystic, partially solid tumor, Type III is a completely solid tumor. Treatment of children with PPB is at the discretion of the treating institution. This study builds off of the 2009 study and will also seek to enroll individuals with DICER1-associated conditions, some of whom may present only with the DICER1 gene mutation, which will help the Registry understand how these tumors and conditions develop, their clinical course and the most effective treatments.
Endoscopic endonasal transsphenoidal surgery is a procedure for the treatment of pituitary macroadenomas that cause visual impairment through optic chiasm compression. The aim of this retrospective study is to describe visual outcome after this procedure.
A multicenter, phase 3, long-term extension trial of TransCon hGH administered once-weekly in children with growth hormone deficiency (GHD) who previously participated in a phase 3 TransCon hGH trial. Approximately 300 children (males and females) with GHD will be included. All study participants will receive TransCon hGH. This is a global trial that will be conducted in, but not limited to, the United States, Poland, Bulgaria, Ukraine, Armenia, Russia and Australia.
Growth hormone secreting pituitary adenomas(GHomas) produce excessive GH, stimulating excessive insulin like growth factor 1(IGF-1) synthesis in the liver, thus causing multiple systemic complications. The life expectancy of patients with untreated GHomas is shortened by ten years. The treatment goal of GHomas is to shrink the tumor volume and normalize GH and IGF-1. Under current treatment, only 50-70% of patients get remission. Rosiglitazone is a widely used oral antidiabetic medicine. The investigator's preliminary data showed that rosiglitazone decreased the synthesis of GH and IGF-1 in rat pituitary tumor cells GH3 and hepatocytes respectively. The investigator plan to investigate the efficacy of rosiglitazone in the treatment of patients with GHomas who have not been alleviated by other therapies.
A 26 week trial of TransCon hGH, a long-acting growth hormone product, administered once-a-week. Approximately 150 children (males and females) with growth hormone deficiency (GHD) will be included. All study participants will receive TransCon hGH. This is a global trial that will be conducted in, but not limited to, the United States, Canada, Australia, and New Zealand.
Pituitary adenoma can be difficult to cure with approximately a third of patients in contemporary series' undergoing incomplete resection. Over the last decade or so a handful of groups have described the use intraoperative ultrasound to improve resection. Although limited, these proof-of-concept studies suggest intraoperative ultrasound is a safe and effective technological adjunct to transsphenoidal surgery for pituitary adenoma. In this prospective development study 30 adult patients will undergo transsphenoidal surgery for pituitary adenoma with prototype intraoperative ultrasound devices. The primary outcomes will be technical feasibility and device safety. The secondary outcomes will be complete versus incomplete radiological resection, endocrinological remission, the occurrence of postoperative complications, operating time, and length of stay.
Clinically nonfunctioning pituitary adenoma remains the only pituitary tumor subtype for which no effective medical therapy is available or recommended. We will evaluate the use of cabergoline in a clinical trial, in order to define the efficacy of this treatment in nonfunctioning pituitary adenoma.
Several studies have been reported that heart rate is known to be associated with prognosis in chronic diseases and acute diseases. For example, a decrease in heart rate following myocardial infarction may lead to a higher mortality rate. It is also known to predict heart failure, diabetic neuropathy, and even depression. The combined pituitary function test artificially induces hypoglycemia to observe the secretion of pituitary hormone. The degree of change in heart rate during hypoglycemia can predict the adequacy of the test, and heart rate can be changed according to the characteristic of the tumor. Also, the prognosis can be predicted based on this. In our study, we used a licensed device approved by KFDA (Korea Food and Drug Administration) to measure heart rate variability in patients with pituitary adenoma.
The purpose of this study is to determine the effects on the heart of injecting local anaesthetic into the nose prior to surgery on the pituitary gland?
Transnasal transsphenoidal (TNTS) resection of pituitary tumors involves wide fluctuation in hemodynamic parameter and causes hypertension and tachycardia due to intense noxious stimuli during various stages of surgery. None of routinely used anesthetic agents effectively blunts the undesirable hemodynamic responses, and therefore usually there is a need to use increased doses of anesthetic agents. Dexmedetomidine (DEX) an α-2 adrenergic receptor agonist, because its sympatholytic and antinociceptive properties may ensure optimal intraoperative hemodynamic stability during critical moments of surgical manipulation. In addition, DEX reduced the anesthetic requirement with rapid recovery at the end of surgery. The main aim of the study was to evaluate the effect of DEX on perioperative hemodynamics, anesthetic requirements
