Tissue repair is an essential process that reestablishes tissue integrity and regular function. Nevertheless, different therapeutic factors and clinical conditions may interfere in this process of periapical healing.The success of root canal treatment is affected by the correct choice of clinical protocol. These factors are dependent on the sanitization process (instrumentation, irrigating solution, irrigating strategies, and intracanal dressing) the apical limit of the root canal preparation and obturation, and the quality of the sealer. The challenges affecting the healing process of endodontically treated teeth include control of the inflammation of pulp or infectious processes and simultaneous neutralization of unpredictable provocations to the periapical tissue.

The aim of the study will be to compare the efficacy of daily plasma exchange (PLEX) versus alternate-day PLEX in achieving a favorable functional outcome in children with autoimmune encephalitis. The study population will be divided into two groups, the first group will perform PLEX on consecutive days and the second one will perform it every other day. Then, A Favorable functional outcome measure defined as modified Rankin Scale (mRS) score ≤ 2. The mRS will be assessed by a blinded assessor at the end of the sessions to determine which method has superior efficacy in treatment of autoimmune encephalitis.

The aim of the study will be to to evaluate whether therapeutic plasma exchange (TPE) reduces mortality in critically ill children with severe sepsis or septic shock compared to the standard care of sepsis alone. The study population will be divided into two groups, the first group will receive standard sepsis management plus therapeutic plasma exchange and the second one will receive the standard sepsis management alone . Then we will assess the effect of TPE on : Severity of organ dysfunction (pSOFA score) , duration of vasopressor support , length of PICU stay, time to hemodynamic stabilization , and on inflammatory and coagulation biomarkers

Several studies evaluated the benefit of a short-term external ureteral catheter (UC) compared to double-J (DJ) ureteral stent after flexible ureteroscopy (URS); the results were controversial. These studies had combined analyses of ureteral and renal stones with a high risk of selection bias. Studies comparing external UC and DJ stent after flexible URS for isolated renal stones are lacking. In the present study, the investigators will compare the outcomes of using a one-day external UC versus a DJ internal ureteral stent for ureteral drainage after retrograde flexible URS (retrograde intrarenal surgery "RIRS") for renal stones. The investigators aim to identify the best ureteral drainage method after RIRS regarding stone clearance, complications, and stent-related symptoms.

This a randomized clinical trial comparing True muscle transplantation surgery versus Augmented Semi hang back recession for treatment of large angle exotropia

Erectile dysfunction is a common condition that may result from vascular, neurological, hormonal, psychological, or medication-related factors. Platelet-rich plasma (PRP) and low-intensity extracorporeal shock wave therapy (Li-ESWT) are regenerative treatment approaches that may improve erectile function through mechanisms involving angiogenesis, tissue repair, and improvement of penile vascular function. This randomized prospective study will compare the efficacy and safety of PRP injection alone with combined PRP injection and Li-ESWT in men with erectile dysfunction. A total of 80 participants will be randomly assigned to two groups. One group will receive PRP injections alone, while the other group will receive PRP injections combined with Li-ESWT. Participants will be followed after treatment to assess changes in erectile function, erection hardness, penile blood flow, patient satisfaction, and treatment-related adverse events. The study hypothesis is that adding Li-ESWT to PRP therapy will result in greater improvement in erectile function than PRP therapy alone.

This prospective randomized controlled trial will compare two surgical methods for treating distal tibial metaphyseal-diaphyseal junction fractures in adolescents aged 10 to 16 years. Participants will be randomly assigned in a 1:1 ratio to receive either elastic stable intramedullary nailing supplemented by Kirschner wires or plate fixation. The study will compare fracture healing, radiological alignment, time to full weight-bearing, functional outcomes, and treatment-related complications. Participants will be followed at 2 weeks, 6 weeks, 3 months, and 6 months after surgery.

This randomized crossover clinical trial compares the passivity of fit of complete-arch mandibular implant-supported frameworks fabricated using three impression techniques: a non-calibrated splinted digital scan body system (IO-Connect), a Reverse Scan Body (RSB) digital impression technique, and a conventional splinted open-tray impression technique. Eight completely edentulous patients each receiving four mandibular implants will be included. Passivity of fit will be evaluated clinically using the Sheffield one-screw test and radiographically using intraoral periapical radiographs obtained with the parallel technique.

Clinical outcomes will include percentage of root coverage, clinical attachment level gain, gingival thickness, probing depth, width of keratinized tissue, post-operative pain, and patient aesthetic satisfaction.

Perioperative pain management in pediatric patients, especially for anorectal and penile surgeries, presents significant challenges for anesthetists. Complications associated with systemic analgesia, such as respiratory issues, cardiovascular problems, and neurological effects, can be avoided by using regional anesthesia. This study aims to evaluate the effectiveness of Ultrasound-Guided Sacral Multifidus Plane Block as a method for perioperative analgesia in high-risk pediatric patients undergoing anorectal and penile surgeries, to reduce the risks associated with systemic analgesia.

The gastric fundus regulates appetite through orexigenic ghrelin-mediated and anorexigenic visceroceptive pathways. Accordingly, endoscopic gastric fundal mucosal ablation (GFMA) may benefit patients with obesity. Ablation not only affects these mechanisms, but similar to what happens after mucosal ablation for other indications (e.g. ESD for tumor removal), it is expected to cause shrinking of the fundus and reduce gastric volume. Another potential target to achieve weight loss is gastric emptying. This is a critical step in digestion that has been found to be more rapid after prolonged exposure to a high-fat diet in both animal and human studies, with rapid emptying also being more common in young people with obesity in some studies. The bariatric endoscopic antral myotomy (BEAM) procedure has been shown to consistently delay gastric emptying without triggering symptoms of gastroparesis and to produce substantial weight loss. Both GFMA and BEAM procedures have the advantages of being minimally invasive, performed completely endoscopic and less costly than surgical alternatives or other known endoscopic techniques like intragastric balloon or endoscopic sleeve gastroplasty.
