There are about 4372 clinical studies being (or have been) conducted in Greece. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The primary aim for this trial is to assess whether the RFA aspirator device is safe and of clinical benefit in patients with primary or secondary malignant liver tumours
The purpose of the study is to assess whether spinal anesthesia is or not superior to the standard general anesthesia for fit patients undergoing laparoscopic cholecystectomy.
Langerhans-cell histiocytosis (LCH) is a rare disease with features of chronic inflammation and hypopituitarism, conditions associated with increased risk of cardiovascular diseases. Objective: To investigate glucose and lipid metabolism, insulin resistance, structural arterial and functional endothelial properties in patients with multisystem LCH in a prospective, observational study. Interventions:Cardiovascular risk factors: arterial blood pressure, lipid profile, mathematical indices of insulin resistance (IR), intima media thickness, brachial artery flow mediated dilatation, dynamic indices of IR, pituitary function and C-reactive protein will be estimated in patients with LCH and in a control group matched for gender, age, BMI and smoking habits.
To evaluate the correlation between endotracheal tube size and incidence of dysfunction of suction lumen of Hi-Lo Evac endotracheal tube in critically ill patients who required mechanical ventilation for more than 48 hours.
The purpose of this study is to compare the efficacy of two controlled ovarian stimulation protocols, the GnRH agonist protocol, widely known as the "long" protocol, and the flexible GnRH antagonist protocol, in terms of pregnancy rates and embryological data, in infertile patients receiving IVF treatment.
The purpose of this study is to compare pregnancy rates and the occurrence of OHSS in PCOS patients who were treated with GnRH agonist and GnRH antagonist protocols ovarian stimulation during an IVF cycle. Our hypothesis is that the GnRH antagonist protocol reduces the occurrence and severity of OHSS compared to the GnRH agonist protocol.
The purpose of the study is to assess whether combined intraoperative ERCP and CBD clearance with laparo-endoscopic rendez-vous during laparoscopic cholecystectomy (one stage approach) is or not superior to the standard practice of preoperative ERCP, sphincterotomy and CBD clearance followed by laparoscopic cholecystectomy (two stage approach) in patients with combined cholelithiasis and choledocholithiasis.
The ICGG Gaucher Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Gaucher disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Gaucher disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Gaucher medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Gaucher disease population. - To evaluate the long-term effectiveness of imiglucerase and of eliglustat. Gaucher Pregnancy Sub-registry: The primary objective of this Sub-registry is to track pregnancy outcomes, including complications and infant growth, in all women with Gaucher disease during pregnancy, regardless of whether they receive disease-specific therapy. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician.If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.
The researchers aim to investigate the outcome (overall survival) of mothers who are diagnosed and/or treated for cancer during pregnancy. Furthermore they want to test the hypothesis that children who were exposed to cancer or cancer treatment (cytotoxic drugs, radiation therapy, targeted therapy,...) develop normally (neurologic and cardiologic examination).
The purpose of this study is to determine if Hemopure® will enhance tissue preservation during Cardiopulmonary Bypass surgery.
