Filter by:The purpose of this study is to discover the potential convenience and ease of using a Magnetic Resonance Imaging (MRI) technique, named Magnetic Resonance Fingerprinting (or MRF), to achieve high-quality images within a short scan time of 5 min for viewing the entire brain. This is an advanced quantitative assessment of brain tissues. This method is being applied with IVIM MRI to be able to tell the difference between a brain with radiation necrosis and a brain with tumor recurrence. Participants will consist of individuals who have received radiation therapy in the past and were diagnosed with radiation necrosis, individuals with recurrent tumors, and healthy individuals who have no brain diseases and have not had radiation treatment to the brain. Participants will undergo an MRI scan at a one-time research study visit; no extra tests or procedures will be required for this research study. The primary objectives of this study are: - To demonstrate the clinical feasibility of combining MRF with state-of-the-art parallel imaging techniques to achieve high-resolution quantitative imaging within a reasonable scan time of 5 min for whole brain coverage. - To apply the developed quantitative approach in combination with IVIM MRI for differentiation of tumor recurrence and radiation necrosis.
A total of 64 primary molars of 5-8 years old children will be randomly selected from Pediatric dental clinic at Faculty of Dentistry, Mansoura University. Children will have two bilateral carious primary molars indicated for pulpectomy ; One side will be treated in one visit and the other will be treated in two visits. Clinical and radiographic evaluation for 3 , 6, 12 months
A prospective, single-arm, intervention study of oral alendronate in adults with sickle cell disease and osteonecrosis
This is a post-marketing surveillance on MiniMAX Stem
The goal of this pilot, randomized, single-blind clinical trial is to estimate the effect size of a high and low mean arterial pressure (MAP)-target algorithm among cirrhosis patients hospitalized with acute kidney injury. The main aims to answer are: • Does an algorithm that has low (<80 mmHg) and high (≥80) MAP-targets lead to significant differences in mean arterial pressure? • Are there any serious adverse events (e.g., ischemia) in a high blood pressure algorithm as compared to a low blood pressure algorithm? • Are there any differences in the incidence of AKI reversal in the high v. low MAP-target groups? Participants will be: 1) Randomized to a clinical algorithm that will either target a low (<80 mmHg) or high (≥80 mmHg) MAP. 2) Depending on their group, investigators will titrate commonly used medications to a specific MAP target. Researchers will compare the high and low MAP-target groups to see if these algorithms lead to significant changes in MAP, if they have any impact on AKI reversal, and if there are any adverse events in the high MAP-target group.
clinically compare the intensity of post-operative pain and the amount of bacterial load reduction after using 20% Epigallocatechin-3-gallate solution during chemomechanical preparation, versus 2.5% NaOCl, in asymptomatic necrotic mandibular premolars treated in a single visit.
Avascular necrosis of the femoral head (AVN) is a progressive pathological process resulting from disruption of blood supply to the femoral head and elevation of intraosseous pressure. total hip arthroplasty is frequently the only durable option for pain relief and restoration of function. this is a single armed study to be done from July 2023 till January 2024, the total number of patients anticipated is 10, total joints treated around 20, The procedure includes core decompression with autologous bone marrow derived mononuclear cell injection inside the femoral head using local anesthesia ultrasound and fluoroscopy guided without drilling.
The objective of this retrospective enrollment/prospective follow-up consecutive series PMCF study is to collect data confirming safety, performance, and clinical benefits of the Longevity IT Oblique and Offset liners when used for primary or revision total hip arthroplasty (implants and instrumentation) at a minimum of 10-year follow-up.
This study aimed to investigate methods for promoting infection control, reducing tissue edema, and preventing excessive spread in diabetes foot ulcers in the necrosis stable stage. Additionally, it sought to explore potential indications for the use of aseptic wound care liquid dressings in these ulcers, with the goal of obtaining evidence-based medical data on their clinical efficacy. Participants will be assigned with a 1:1 ratio into intervention group and control group. Participants in the intervention group will be irrigated with sterile liquid dressing for each wound treatment on the basis of clinical standard treatment protocols for 2 weeks, until the end of the 2-week observation period. Participants in the control group will be irrigated with normal saline for each wound treatment for 2 weeks on the basis of the clinical standard diagnosis and treatment plan, until the end of the 2-week observation period.
The study is designed to assess the efficacy of vancomycin powder and dilute povidone-iodine lavage (VIP protocol) in reducing the PJI after primary Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA). We hypothesized that VIP protocol provides superior reduction of periprosthetic joint infection (PJI) rates after primary THA and TKA compared with diluted povidone-iodine (PI) protocol.
