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.
Polycythemia vera (PV), a hematological neoplasm characterized by excessive erythropoiesis due to Janus kinase 2 (JAK2)- activating mutations. On the other hand, patients with secondary polycythemia (SP), a disorder mostly caused by an increased red cell mass due to chronic hypoxia (i.e, pulmonary disorders and smoking) and erythropoietin-producing tumors (such as leiomyoma, hemangiomas, renal cysts and various carcinomas), are phenotypically slightly different and are usually considered to have significantly better outcomes. Red blood cell distribution width (RDW) reflects the heterogeneity of red blood cell sizes (anisocytosis) and is routinely reported as a part of complete blood count by automated instruments in hematology laboratories.
In around 90% of the patients with MPNs, an acquired mutation that promotes JAK/STAT signaling is identified [3, 4]. The JAK/STAT pathway transduces signals from cytokines including erythropoietin, thrombopoietin, and granulocyte colony-stimulating factor.24 A point mutation that activates JAK2, JAK2V617F, is present in around 95% of patients with PV and 40% to 60% of patients with ET and MF
The hypothesis of the study will be that the ratio of femoral vein diameter to femoral artery diameter will have correlation with fluid status in pediatrics.
Obstructive sleep apnea (OSA) is a serious and often underreported condition, despite its highly prevalent distribution. Medical teams play an integral role in screening and managing patients with a high risk of developing OSA.
Postoperative pain is an important problem, especially for day case surgeries. It has negative effects on patient's hemodynamics and can cause delayed ambulation resulting in prolonged duration of hospital stay and poor patient satisfaction. Multiple analgesic strategies have been proposed including NSAID, opioids, epidural analgesia. Each of them has its limitations. In this study the investigators will compare between the effect of preemptive use of paracetamol plus tramadol versus preemptive intravenous fentanyl in controlling postoperative pain
A within-subject cross-over study is done on eight completely edentulous patients to compare two different complete removable dentures. Group I: Heat cured Conventional complete dentures designed based on the neutral zone concept; Group II: CAD-CAM neutral zone complete dentures designed based on the neutral zone concept. Occlusal analysis is done by the T-Scan device, and evaluation of muscle activity is conducted by electromyography at insertion time, two weeks after insertion time, and one month after insertion time.
The study suggests that if the investigators used customized healing abutments synthesized from PEEK may have a favorable effect on peri-implant soft tissues regarding decreased plaque accumulation and healing stimulation compared to the customized conventional titanium healing abutments.
Nausea and vomiting are some of the most common complaints of patients after any anesthesia, which is often associated with postop-erative pain. The double-blind clinical trial study aimed to compare the prophylactic effect of dexamethasone and dexmedetomidine and their combination in reducing postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy.
Ulcerative colitis (UC) is one of the most common types of chronic and non-specific inflammatory bowel diseases (IBD). It is characterized by cytokine-induced continuous and diffuse inflammatory infiltrations into the rectum's mucosa and extends proximally to the colon. Patients with UC predominantly have bloody diarrhea, abdominal pain, fecal urgency, and tenesmus, which extremely alters their quality of life. Although the precise pathological mechanism of UC remains unclear, several studies have been outlined many factors that could involve in the pathogenesis of UC, including, but not limited to, initiation of the inflammatory response, disruption of oxidant/antioxidant status, dysregulation of the immune response, alteration of gut microbiota, and delaying epithelial barrier healing. Loss of intestinal barrier function and dysregulated immune response are the key events during colitis development
Inhalation injury is a composite of multiple insults including: supraglottic thermal injury, subglottic airway and alveolar poisoning, and systemic poisoning from absorbed small molecule toxins. These contaminant insults independently affect each of the pulmonary functions as well as having a direct effect on systemic physiology. Further, anatomic characteristics can predispose patients to inhalation injury. For example, an infant will develop airway obstructions much faster than an adult due to reduced airway diameter. Understanding the contributions of each of these pathologies to the patient's disease is critical to managing inhalation injury.
