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.
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
DTI and auditory tractography can be incorporated into the diagnostic toolkit for patients who are scheduled to undergo cochlear implantation and whose standard assessments have been unable to determine the functional integrity of the auditory pathway. These techniques aid in decision-making processes regarding potential outcomes, determining the optimal side for implantation, providing counseling regarding the possibility of limited benefits from surgery, and considering alternative forms of rehabilitation. The investigators including patients with varying degrees of hearing loss, as well as patients with normal radiological findings who are scheduled for cochlear implantation. The ultimate goal is to create a comprehensive map across the entire hearing spectrum and validate the findings of this study..
The aim of the present study is to compare between general anesthesia versus sedation with dexmedetomidine and ketamine with local infilteration at the catheter insertion site in pediatric patients undergoing transcutaneous closure of atrial septal defect on hemodynamic changes.
This study aimed To investigate the effects of different doses of Intraoperative intravenous lidocaine infusion on intraoperative opioid consumption, perioperative pain control and incidence of postoperative chronic pain.
Background In practice, however, not all anaemic patients undergo appropriate diagnostic tests for the detection of iron deficiency anemia (IDA), and a significant portion of patients with IDA do not receive endoscopic evaluations. Accordingly, this study aimed to detect the prevalence of significant endoscopic (upper and lower endoscopy) and pathological findings in patients presenting with unexplained iron deficiency anaemia. Methods One hundred twenty-four patients with confirmed IDA with no obvious cause who visited the Internal Medicine Clinic were randomly selected. Patients with active bleeding, pregnant or lactating females, or those with contraindications to sedation were excluded. Upper and lower endoscopy were held in the endoscopy unit of Specialized Medical Hospital and tissue biopsy from significant endoscopic findings was sent for histopathological examination.
This study aims to evaluate the possible nephroprotective effect of nicorandil in patients with type 2 diabetes mellitus .
The aim of this study is to clinically and radiographically evaluate the dimensional changes of hard tissue after using Partially Demineralized Dentin Block versus Xenograft in the esthetic zone. The main question: In patients with unrestorable teeth, will the use of partially demineralized Dentin Block be more effective than Xenograft in preserving vertical and horizontal ridge dimensions? After enrollment, a thorough preoperative assessment, including history taking, clinical, and radiographic examinations, will be conducted. Initial therapy includes periodontal treatment (phase 1 therapy) followed by random assignment to one of two treatment groups: ridge preservation using Partially Demineralized Dentin Block or Xenograft. Both groups will undergo atraumatic extraction. For the test group, an autogenous partially demineralized dentin graft will be prepared, involving tooth cleaning, grinding, and partial demineralization with the Tooth Transformer device, followed by Leukocyte-Platelet Rich Fibrin (L-PRF) membrane and liquid fibrinogen preparation. The L-PRF membranes will be cut, mixed with dentin particles, and combined with liquid fibrinogen to form a compact graft. The block will be placed inside the socket and covered by an L-PRF membrane and secured with a cross-suture. In the control group, Xenograft will be used, and the socket filled with deproteinized bovine bone mineral, covered with a collagen membrane, and secured with a cross-suture. After a healing period of 6 months, at the time of implant placement, a biopsy will be taken using a trephine bur.
Red blood cell (RBC) transfusion is a common therapeutic approach, and almost 85 million packed red blood cells (pRBCs) are transfused annually worldwide.Transfusion efficacy largely depends on the patient's general health, but the composition of transfused pRBCs also can have an impact.
This study is designed to assess the impact of injecting sodium hyaluronic acid versus a chitosan-hyaluronate hybrid gel into the upper compartment of the temporomandibular joint (TMJ) as a treatment for anterior disc displacement without reduction. The study will include patients diagnosed with Stage III or IV TMJ internal derangement (anterior disc displacement without reduction), as classified by Wilkes, with diagnoses confirmed through clinical symptoms and MRI evaluations. Participants will be randomly divided into two groups, both undergoing TMJ arthroscopy. In the first group, 2 ml of chitosan-hyaluronic acid hybrid gel will be injected into the affected joints, whereas in the second group, 2 ml of hyaluronic acid (HA) will be administered. The study will compare and analyze outcomes in both groups, focusing on pain during TMJ function, clicking sounds, the extent of maximum mouth opening, and maximum lateral jaw movement.
Thoracic surgeons have developed a thoracoscopic procedure which is less intrusive method allows complete evacuation and washing of the debris from the pleural cavity. This approach may also have the benefit of less invasive maneuver, a shorter hospital stay and a decreased rate of postoperative complications. The aim of this study is to evaluate the advantages and disadvantages of the video-assisted thoracoscopic surgery (VATS) approach in comparison with thoracotomy in management of empyema in pediatric patients.
