There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. 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.
General anesthesia may be non preferable in many patients undergoing Phakic IOL surgery, as most of the surgeries take 5-10 minutes at maximum.Traditionally, retrobulbar injections were performed deep into the orbit, but it is now accepted that peribulbar injections using shorter needles are safer. In the last few years, continuing concern over the rare but serious complications of sharp needle blocks has led to increasing interest in the use of sub-Tenon`s blocks utilizing a blunt cannula 1-5. Even with the use of blunt canulae sub-Tenon`s block, serious problems can still occur, especially in myopic patients with large axial length. In phakic IOL surgery,topical anesthesia has been used successfully for years. Topical anesthesia has several advantages over regional infiltrative techniques, the foremost of which is the abolition of any risk of inadvertent injury of the globe or orbital contents 6,7,8. It has a high rate of patient satisfaction, but still there are some patients that experience intraoperative discomfort. In this study we compared topical anesthesia alone with topical anesthesia plus intracameral lidocaine 1% in patients undergoing posterior chamber phakic intra ocular lens;Vision implantable collamer lens ( ICL/toric ICL) surgery.Intracameral anesthesia is a common adjunct to topical anesthesia in anterior segment surgery9. It probably provides sensory blockage of the iris and ciliary body and thereby relieves discomfort experienced during IOL placement. Intracameral lidocaine alone dilates the pupil well 10 and this is believed to be because of the direct action of lidocaine on the iris, which in turn causes muscle relaxation.
Following the findings of the clinical trials in drug development, this global non-interventional cohort field study will investigate rivaroxaban under clinical practice conditions in comparison with current standard of care for patients with acute venous thoromboembolism (VTE). The main goal is to analyze long-term safety in the use of rivaroxaban in the treatment of acute VTE in routine clinical practice.
The purpose of this clinical study is to test the hypothesis that market released Cardiac Resynchronization Therapy (CRT) devices which contain the AdaptivCRT® (aCRT) algorithm have a superior outcome compared to standard CRT devices in CRT indicated patients with normal atrio-ventricular (AV) conduction and left bundle branch block (LBBB).
The primary aim of this randomized multi-center trial is to investigate the efficacy of the radiotherapy regimens 5 x 4 Gy and 10 x 3 Gy with respect to the effect on motor function in patients with metastatic epidural spinal cord compression.

There is initial evidence that the choice of anesthesia can influence survival in the specific setting of coronary artery bypass grafting surgery (CABG). A recent international consensus conference included volatile agents among the few drugs/techniques/strategies that might reduce perioperative mortality in cardiac surgery and that should be further studied. Volatile anesthetics (desflurane, isoflurane and sevoflurane) have non-anesthetic pharmacological characteristics that confer cardiac protection when compared to Total IntraVenous Anesthesia (TIVA). Several randomized controlled studies were summarized in a meta-analysis that documented a reduction in perioperative cardiac troponin release and mortality in patients receiving volatile anesthetics when compared to patients receiving a TIVA. There are four published studies (Bignami et al. 2009) (De Hert et al. 2009) (Jackobsen et al. 2007) (Landoni et al. 2007) suggesting that these benefits can translate into a reduced mortality rate in patients receiving volatile agents. The level of evidence for these four studies is not high (one meta-regression, one underpowered randomized controlled study, one retrospective study and one meta-analysis of small randomized studies) and there is need for a large multicentre randomized controlled study to confirm these findings, as suggested by the international consensus conference on this topic published in 2011 (Landoni et al 2011). The purpose is to provide a large multicentre controlled randomized trial to demonstrate that volatile anesthetics can reduce 1 year mortality from 3% to 2% in patients undergoing CABG (either with or without cardiopulmonary bypass). The results of this study can support the use of volatile agents in all CABG procedures worldwide (more than 500.000 per year) with 2.500 lives saved per year (in the hypothesis that nowadays half the procedures are performed with a TIVA and that 1 year mortality can be reduced from 3% to 2% using volatile agents).
Research Problem: Bladder cancer is one of the major health concerns of the world. The present methods of diagnosis are: Ultra sound, Cystoscopy, CT scan and urine cytology. All these are stressful to the patients, particularly Cystoscopy which is commonly employed for the follow up of Bladder cancer patients. Research Significance: The present study will employ a new photodynamic diagnostic procedure to quantify a certain cancer specific biomarker called Porphyrin, which selectively binds on to the bladder cancer tissues. In this context the present technique offer viable, very easy and reliable table top instrumentation for diagnosis and continual monitoring of disease regression through urine. Research Objectives: - To quantify bladder cancer specific biomarkers such as Porphyrin using photodynamic diagnostic procedure - To find out whether this technique might be a new and easy tool for bladder cancer diagnosis only by urine. Research Methodology: The bladder cancer patients is required to swallow a chemical called ALA (5 Amino levulinic Acid hydrochloride), about 10mg/kg body weight which will play a role of biological indicator. ALA gets metabolized into certain types of porphyrins which selectively bind on to the tumor tissues (for a longer time than the normal tissues). 5ml of blood and one urine samples will be taken before using ALA. The patient must drink water then the urine will be collected after 4, 8 and 12 hours of taking ALA and the samples will be analyzed by photodynamic diagnostic procedure.
Ultra-wide field fluorescein angiography can detect the response of anti VGEF therapy such as Avastin on retinal ischemia in the setting of diabetic macular edema.
