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.
Laparoscopic cholecystectomy has been established as the treatment of choice for symptomatic gallstone disease. The main advantages of laparoscopic surgery are the cosmetic result, reduced postoperative pain, shorter hospital stay and rapid return to normal activity. Although reduced, however, pain is still substantial and constitutes the main clinical problem after laparoscopic cholecystectomy, especially for planned day case procedures. Recently, a new technique of laparoscopic cholecystectomy has been developed, in which all instruments are inserted through the same umbilical incision. The single incision laparoscopic surgery (SILS) technique for cholecystectomy has been proved to be feasible and safe by several studies. The purpose of the study is to compare postoperative pain and operating time, nausea, vomiting, tissue damage, pulmonary function, cosmetic result, quality of life between SILS and standard laparoscopic cholecystectomy.
This is a cross-sectional study including patients with permanent atrial fibrillation. Assessment will include: - clinic blood pressure measurements (mercury sphygmomanometer and automated oscillometric device) - 24-hour ambulatory blood pressure monitoring - determination of various serum markers and cardiac ultrasound. - evaluation of a 24h ambulatory blood pressure monitoring device (Microlife WatchBPO3) in terms of its diagnostic value for the detection of atrial fibrillation compared with the reference 24h Holter ECG
The purpose of this study is to compare the effects of a pulsed application of Levosimendan versus placebo on the composite end-point functional capacity and quality of life.
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.
Hypocalcemia is one of the most frequent complications of total thyroidectomy, a procedure used for benign as well as malignant conditions of the thyroid gland. Postoperative hypocalcemia is usually caused by hypoparathyroidism. Vitamin D is implicated in calcium metabolism as it increases intestinal calcium transport and regulates parathormone production. Aim of the present study is to evaluate preoperative vitamin D levels as a prognostic factor for postoperative hypocalcemia and hypoparathyroidism.
The Icatibant Outcome Survey (IOS) is a prospective, observational disease registry designed to document the routine clinical outcomes over time in participants with angioedema treated with Firazyr® (icatibant) and/or Cinryze® (C1 inhibitor [human]) in countries where it is currently approved. The data collected will be used to evaluate the safety of Firazyr (icatibant) and Cinryze (C1 inhibitor [human]) in routine clinical practice and as a data source for post-marketing investigations.
Hypocalcemia is the complication, after total thyroidectomy, that usually determines the length of hospital stay.Serum calcium levels is a quick and cost-effective practice to recognise hypocalcemia in the postoperative follow up. OBJECTIVE: The objective of this perspective study is to determine if consecutive postoperative serum calcium levels early after total thyroidectomy can be used to identify patients who are unlikely to develop significant hypocalcemia and can be safely discharged within 24 to 48 hours postoperative.
The aim of this study is to compare the effects of high-dose furosemide versus low-dose furosemide combined with low-dose dopamine on diuresis, renal function, electrolyte balance, and 60-day post-discharge outcomes in patients hospitalized with acute decompensated heart failure.
The trial randomise patients with asymptomatic carotid artery narrowing in whom prompt physical intervention is thought to be needed, but there there is still substantial uncertainty shared by patient and doctor about whether surgery or stenting is the more appropriate choice. The study is looking at immediate risks (within one month)and at long term benefits
Study Objectives: To collect and describe demographics, disease-management, and treatment outcomes of Myelodysplastic Syndromes (MDS) patients who are newly diagnosed and classified according to the World Health Organization (WHO) criteria. To perform observational studies concerning relevant scientific research questions in MDS using clinical data and biological samples, and to present relevant research outcomes in the fields of diagnosis and prognostication, health related quality of life issues, health economics, and risk stratification for newly developed classes of drugs. To disseminate results of the studies to all stakeholders involved.
