Filter by:Six patients with diagnosed bone loss of the hip who have consented to minimally invasive repair will be approached to participate in the study. Participants will have the liquid portion of bone marrow collected using the Zimmer Biomet Biocue system, which is the standard system used by physicians at The Ohio State University, and the novel Marrow Cellutions system™. Bone marrow liquid will be collected from the surgical hip using the Zimmer Biomet Biocue system, and the Marrow Cellutions system™ will be used to collect bone marrow liquid from the non-surgical hip. Following collection, the bone marrow liquid will be processed using the respective systems to concentrate the cells and molecules found in the bone marrow liquid. As part of the standard of care for this arthroscopic procedure, concentrated bone marrow liquid processed using the Zimmer Biomet Biocue system will be delivered to the surgical site as an adjunct to promote healing. Concentrated bone marrow liquid prepared with the Zimmer Biomet Biocue system is given as part of the standard of care for patients undergoing minimally invasive treatment for bone loss of the hip; therefore, the target population for this study are individuals between the ages of 18-50 years with confirmed bone loss of the hip who have consented to minimally invasive repair. In addition to the concentrated bone marrow liquid prepared using the Zimmer Biomet Biocue system, patients will also have bone marrow liquid collected from the non-surgical hip using the Marrow Cellutions™ system. Only concentrated bone marrow liquid produced with the Zimmer Biomet Biocue system will be given to the patient. All concentrated bone marrow liquid produced with the Marrow Cellutions™ system will be sent to the laboratory for analysis. Additionally, white blood cells will be concentrated into an autologous protein solution (APS) using the Zimmer Biomet Plasmax system from blood collected using a routine blood draw. All protein solution produced will be sent to the laboratory for analysis. No protein solution will be given to the patient. As the bone marrow liquid collection using the Marrow Cellutions™ system and the blood draw to produce protein solution using the Zimmer Biomet Plasmax system are being performed for research,
Regenerative endodontic procedures are intended to replace damaged tooth structures, including dentine and root structures, in addition to cells of the pulp-dentine complex. This treatment modality have been tested on immature necrotic teeth because they are anticipated to have a greater chance of pulp tissue regeneration. However, it has been recently suggested for treating fully formed mature necrotic permanent teeth with closed apices since the conventional root canal treatment yielded many drawbacks. A number of studies have evaluated the regeneration outcomes of using blood clot as a scaffold. However, there are limited studies in the literature on using other scaffolds such as platelet-rich fibrin (PRF). This clinical study will evaluate clinically and radiographically the effectiveness of PRF versus induced bleeding in treating mature necrotic teeth. Fifty patients with necrotic mature teeth with periapical lesions will be invited to participate in this study. Teeth will be treated using calcium hydroxide as intracanal medicament then using PRF (n=25) and blood clot (n=25) as scaffold. All teeth will be sealed coronally using NeoMTA Plus™. Treated teeth will be assessed clinically and radiographically using 2D periapical radiographs. The reported clinical and radiographic outcomes will be compared using SPSS.
Acute pancreatitis is one of the most common gastrointestinal disorders requiring hospitalization worldwide. Pancreatic fluid collections can occur as a consequence of acute and chronic pancreatitis and can result in significant morbidity and mortality, including significant abdominal pain, gastric outlet obstruction, biliary obstruction, organ failure, persistent unwellness, infection and sepsis. Symptomatic pancreatic fluid collections require treatment, and endoscopic drainage is considered standard of care. The aim of this study is to evaluate the treatment outcomes in patients undergoing standard of care, endoscopic treatment of pancreatic fluid collections.
The goal of this randomized clinical trial is to compare immediate placement of an overlay after root canal treatment with delayed placement of the overlay leaving the tooth one week in infra occlusion. The main question it aims to answer are: type of study: clinical trial participant population/health conditions: patients more that 18 years old who need a root canal treatment in posterior teeth with antagonist teeth. question 1: postoperative pain after 6 hours question 2: postoperative pain after 12 hours question 3: postoperative pain after 24 hours question 4: postoperative pain after 48 hours question 4: postoperative pain after 72 hours If there is a comparison group: Researchers will compare immediate overlay placement and delayed (1 week) overlay placement after root canal treatment to see if there is more pain in one group than in the other.
The goal of this randomized clinical trial is to find the most effective Bioceramic-based apexification procedures in children with immature necrotic maxillary incisors. The main questions they aims to answer are: - What is the best Bioceramic apexification technique regarding the post-operative pain and the periapical healing ? - What is the best Bioceramic apexification technique regarding the bioceramics extrusion and the required time ? Participants will under gone Bioceramic apexification procedures which root canal preparing, disinfecting, filling, and restoring. Then, the patient will asked to come to follow-up appointments for clinical and radiological evaluations If there is a comparison group: Researchers will compare Bioceramic Putty Apical Plugs, Single Cone Gutta-percha with Bioceramic Sealer, and Combination of Bioceramic putty and sealer technique to find the best effective technique.
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.
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 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.
This is a post-marketing surveillance on Medacta Shoulder System
During the performance of oncoplastic surgery and skin-sparing or skin-nipple mastectomy there is a significant loss in the perfusion of the cutaneous envelope of the breast, which can produce areas of vascular suffering of the skin that sometimes cause necrosis of the same. Skin necrosis is the most important adverse event in oncoplastic and reconstructive surgery of the breast, since it causes delays in adjuvant treatments to surgery, worsening of the cosmetic result, and, on occasions, loss of the implant and reconstruction. Indocyanine color green (ICG) angiography has been proposed as a diagnostic alternative to determine the vascular perfusion of the skin envelope of the breast during surgery, which would allow the removal of tissue at risk of necrosis to avoid this complication during the postoperative period. However, the scientific literature does not currently allow an adequate assessment of this diagnostic procedure due to the absence of prospective studies that have evaluated its sensitivity, specificity, and predictive values. The objective of this prospective study is to evaluate ICG angiography of skin flaps of the breast and the surgeon's decision in women with breast cancer or at high risk for breast cancer undergoing oncoplastic surgery or mastectomy with the help of skin or skin-nipple. Based on the results of this study, the sensitivity, specificity, and predictive values of this technique for the prediction of adverse events during the postoperative period will be established.
