There are about 11256 clinical studies being (or have been) conducted in Egypt. 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.

Spinal anesthesia is commonly used in cesarean section surgeries . The most important adverse effects of spinal anesthesia are hypotension and bradycardia caused by sympathetic blockade, with an incidence of about 55-100% . However, blocking the venous return by the gravid uterus increases the risk of hypotension. Spinal anesthesia-induced hypotension is commonly associated with uncomfortable symptoms, such as shivering , nausea and vomiting, in the mother. Prolonged maternal hypotension may lead to serious maternal adverse effects, such as cardiovascular collapse, loss of consciousness, apnea, and aspiration of gastric contents. In addition, uteroplacental blood flow decreases in cases of sustained hypotension and detrimental neonatal effects, such as fetal acidosis and fetal death, may occur. Preventing spinal anesthesia-induced hypotension during cesarean section is essential for the well-being of both the mother and neonate. Also, Shivering often happens after spinal anesthesia. Shivering is an unconscious and rhythmic movement involving several groups of muscles. The increase of muscle activity generates the elevation of oxygen consumption, lactic acidosis, and carbon dioxide production In recent years, researchers have focused on the effects of the Bezold-Jarisch reflex (BJR) . This reflex includes a triad of bradycardia, hypotension, and apnea. Researchers have suggested that serotonin and 5-hydroxytryptamine 3 (5-HT3) receptors play an important role in the occurrence of the BJR after spinal anesthesia . The 5-HT3 receptors are present in the heart, lung, and spine. Diminished venous return caused by spinal anesthesia stimulates the cardiac chemoreceptors, and parasympathetic activity increases, which results in bradycardia and hypotension . Studies have suggested that the use of 5-HT3 antagonists may attenuate spinal anesthesia-induced hypotension, thus inhibiting peripheral vasodilatation, alleviating the BJR, and increasing venous return to the heart . Ondansetron is a commonly used 5-HT3 receptor antagonist, and its peak plasma concentration occurs within 30 min following IV injection. Granisetron is a new 5-HT3 receptor antagonist, and the onset of action occurs 30 min following its IV administration [
The goal of this interventional randomized clinical trial is to evaluate the use of platelet rich fibrin in full pulpotomy in mature adult teeth. The main questions it aims to answer are: 1. Does the use of platelet rich fibrin in complete pulpotomy in mature permanent teeth will raise the success rate of full pulpotomy of adult teeth? 2. Does the use of cone beam computed tomography scans will be more effective in early detection of apical periodontitis than periapical radiographs? Participants will be asked to do the following: - Receive the pulpotomy treatment of their target tooth. - Record the pain score in the pain assessment chart. - Attend the follow-up visits. They'll receive a full pulpotomy treatment of their target tooth. Researchers will evaluate the usage of platelet rich fibrin in performing the pulpotomy procedure of adult teeth and if cone beam computed tomography scans will be more effective in early detection of apical periodontitis than periapical radiographs.
Distal tibial fracture management is difficult because of poor blood supply resulted from subcutaneous location. Therefore, the study aims to compare expert intramedullary nail (IMN) with poller screws to the distal tibial locked plate regarding operative and complications outcomes
Femur's neck injuries are frequently encountered fractures. They are usually due to high energy or low energy indirect trauma. Healing of these fractures is usually hindered due to "avascular necrosis (AVN)" or "non-union" of the Femur's head. This study looks forward to investigating the impact of capsulotomy and internal fixation in lowering the incidence of complications and improving the functional outcomes.
The aim of the study is to clinically and radiographically evaluate and compare two techniques to augment soft tissues: the conventional subepithelial connective tissue graft technique and a novel denuded interpositional pedicled rolled flap technique (DIPRF) These techniques will be used to augment edentulous ridges that are recommended for rehabilitation by an implant or a fixed restoration.
This study aims to evaluate and compare the quantity of the radiographic horizontal bone gain of severely deficient complete maxillary ridges reconstructed by bone block harvest from the iliac crest versus the calvarial bones
Introduction Cerebral palsy (CP) is a group of sensory, motor, and postural disorders caused by non-progressive brain injury in early development. It can manifest in various forms, including hemiplegia, which affects about 21% to 40% of CP cases. Upper extremity (UE) impairments in CP individuals are significant, impacting daily activities and quality of life. Objective This study aims to investigate the effects of pulley system exercises on improving upper limb function in children with hemiplegic CP. Methods Design: Randomized controlled double-blinded trial. Participants: 32 children aged 3-7 years with hemiplegic CP, divided into intervention and control groups. Intervention: The intervention group receives pulley system exercises plus standard care, while the control group receives standard physical therapy. Duration: Conducted between June 2024 and August 2024. Inclusion Criteria: Diagnosed with hemiplegic CP, aged 3-7 years, able to follow instructions, and with upper limb motor deficits. Exclusion Criteria: Additional neurological disorders, recent upper limb surgery, previous rehabilitation programs, severe medical conditions, or contraindications to physical activity. Assessment Tools: Assisting Hand Assessment (AHA), Bruininks-Oseretsky Test of Motor Proficiency (BOT-2), Quality Upper Extremity Skills Test (QUEST), and Lafayette Manual Muscle Tester. Timing: Baseline and after 3 months of intervention. Treatment Intervention Group: 45-60 minute sessions, three times a week, involving warm-up, pulley system exercises, and cool-down. Control Group: Standard care physical therapy, twice a week, 45-60 minute sessions. Statistical Analysis Methods: Descriptive statistics and Analysis of Covariance (ANCOVA) to analyze improvements in upper limb function. Significance Level: p < 0.05. Analysis: Intention-to-treat to handle missing data. This study aims to provide evidence on the effectiveness of pulley system exercises in enhancing upper limb function in children with hemiplegic CP, potentially improving their independence and quality of life.
