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.
Investigators aim to evaluate the ocular penetration of topical tacrolimus 0.03% eye drops. Topical tacrolimus 0.03% will be instilled into the eyes of patients 15 minutes before cataract surgery. Aqueous samples will be collected at the time of cataract surgery and will be subjected to detection of presence and level of tacrolimus.
The study will evaluate the vital signs changes during 3 different dental procedures performed for the same patient by the same dentist. The patients will be selected randomly and should all be healthy adults. The aim is to look for any significant changes in the major vital signs (heart rate, respiratory rate, blood pressure, peripheral capillary oxygen saturation (SpO2) and body temperature) during specified dental procedures (scaling, simple restoration, and simple exodontia) and compare the changes between the 3 procedures.
The purpose of this study is to evaluate the thoracic skin to epidural space depth in children and define the ratio between the straight and inclined thoracic skin to epidural depth.
The efficacy and safety of different medications vary from one individual to another and from one ethnic group to another. Therefore, strong interest in the study of pharmacogenomic and pharmacoepidemiology has evolved recently. There are multiple examples of oncology drugs being more effective in certain ethnic population compared to other. For example, irinotecan combined with cisplatin was very effective drug in the management of small cell lung cancer in the Japanese patients while an identical study done in the US revealed no major benefit to this combination in American population
This study will have great impact and influence in the medical setting as the targeted model that will be derived from this study will be the pioneer in our region. This model will be beneficial in identifying risk factors and its association with the Arab women population. Furthermore, it will bring chemotherapy prevention once the risk factors and the model are established. Risk factors maybe different from those identified in western women by Gail and IBIS Models
Sickle cell disease (SCD) is the most common inherited blood disorder in Saudi Arabia . Its clinical severity is widely heterogeneous among patients who share the same genetic mutation . Severe frequent pain crisis, recurrent acute chest syndrome and stroke are features of severe SCD. Hydroxyurea is an effective treatment of SCD as it ameliorates the severity and frequency of pain crisis and acute chest syndrome and decreases mortality, however, it is less effective in the prevention and treatment of stroke and other end organ dysfunctions . The only readily available cure of SCD is by hematopoietic stem cell transplantation (HSCT) . Most children with SCD who are treated by HSCT receive myeloablative conditioning with excellent results. The application of reduced intensity (RIC) and non-myeloablative (NMA) conditioning regimens are reserved for patients older than 16 years of age because of the increased risks of morbidity and mortality after HSCT6. However, infertility and gonadal failure after myeloablative conditioning are important barriers to the willingness of patients and their families to undergo HSCT . The development of an effective RIC HSCT in SCD that might spare the fertility of SCD patients would have obvious merit. With the ultimate goal of expanding this curative therapy to SCD patients, we propose to investigate HSCT with a RIC conditioning regimen. We will carry out a pilot study of HSCT from HLA matched sibling donors using thymoglobulin/fludarabine/melphalan conditioning and sirolimus and mycophenolate mofetil (MMF) as GVHD prophylaxis in SCD patients with severe complications such as stroke and other severe complications. We hypothesize that HSCT from HLA matched sibling using thymoglobulin/fludarabine/melphalan conditioning in SCD will maintain a level of stable donor chimerism that is sufficient to cure SCD with minimal toxicity.
End-of life care is one of the principle components of cancer care. Measurement of the quality of care provided for end-of-life cancer patients is an important issue. Recently there has been an increased emphasis on measuring and monitoring the quality of cancer care for the purpose of improving clinical practice. Despite increasing attention paid to end-of-life care in recent years, many studies have described difficulties in the final phase of life, including problems with access to hospice, inadequate symptom management, care giving burdens, care mismatched with patient preferences, and inappropriate resource use. Measuring quality of life is an important issue for monitoring clinical practice and improving outcome. Although patient assessment is the best quality measure, it is impractical to measure the quality of end-of-life care because of the difficulties of accurate prognostication for end-of-life and many patients are too ill to provide assessments. In contrast, several recent studies developed quality indicators (QIs) of palliative and end-of-life care, which assess the quality from existing sources such as administrative data or medical chart data.
CT and MRI based measurements of the pediatric airway has changed the age-old cone shape concept of the pediatric airway and define airway shape as elliptical structure. The cone shape was based on the cadaveric measurements done by Bayeux in 1897 and described later by Eckenhoff in 1951. The present study is based on three-dimensional CT images of the airway column replicating the cylinders used by Bayeux for his cadaveric measurements. The purpose of this study was to determine the cone shape of the pediatric airway.
The aim of this study was to formulate a mucoadhesive gel of grapes seed extract (GSE) followed by short-term clinical study for the effectiveness of this gel onto the pocket depth (PD), plaque index (PI), gingival index (GI), and bleeding on probing (BOP) when applied in periodontal pockets as an adjunct treatment for chronic periodontitis.
A multi-centre, randomized, placebo controlled, trial. Participants at high-risk for vascular events from the network of INTER- CHF will be randomized to inactivated influenza vaccine or placebo and followed prospectively over three influenza seasons. 5,000 participants will be enrolled prior to influenza season, randomized to either influenza vaccine or saline placebo, either of which they will receive annually for three years and then followed over each of the influenza seasons.
