C11-Sodium Acetate PET/CT Imaging Evaluation in Brain Glioma, Post Therapy Necrosis and Pseudo-progression...
GliomasThis study will investigate how well Carbon Acetate PET/CT imaging helps to correctly identify recurrent tumor versus post treatment effects (radionecrosis) in patients with previously treated high grade brain gliomas.

Effect of BM-MSCs in DCD Kidney Transplantation
Kidney TransplantationAcute Kidney Tubular NecrosisThis study is designed to determine the efficacy and safety of allogeneic bone marrow-derived mesenchymal stem cells in kidney transplantation from Chinese donation after citizen's death (DCD). A pair uremia patients receiving kidney grafts from a same donor are randomized into two groups: MSCs group and control group. Besides routine induction therapy (ATG or Basiliximab) and maintenance immunosuppressive drugs (low-dose Tacrolimus + MPA + prednisone), patients in MSCs group are administered MSCs treatment (1*10^6/kg). Allogeneic bone marrow-derived MSCs (1*10^6/kg) are given intravenously at day 0 (post renal reperfusion during surgery), day 7, day 14 and day 21. The renal allograft function, rejection, patient/graft survival and severe adverse events within 12 months post-transplant are monitored.

Antimicrobial Effect of Modified Antibiotic Nanofibers for Regenerative Endodontics Procedures
NecrosisPulpThe treatment for immature teeth with pulp necrosis can be carried out through apexification or regenerative endodontics procedures including platelet rich plasma (PRP), platelet rich fibrin (PRF) and injectable PRF, these techniques used alone or in combination. Revascularization therapy carries on more advantages than apexification, such as inducing root-end development and reinforcement. However, apical repair will not happen in the presence of inflamed and infected tissue.the aim of this study is to evaluate the antimicrobial effect of pre-synthesized novel antibiotic loaded electrospun nanofibers used in patients with immature necrotic teeth.
Antimicrobial Efficacy of Four Different Irrigation Protocols
Dental Pulp Necrosisproper disinfection of root canal system before obturation is a must for long term success of endodontic treatment, therefore a proper irrigant is mandatory, therefore investigators are studying the antibacterial effects of 4 different irrgating solutions in root canal treatment of patients diagnosed with necrotic pulps in their mandibular posterior teeth. patients will be recruited from outpatient clinic of the endodontic department in cairo university. endodontic treatment will be carried out as usual and samples from the infected root canals will be collected before and after preparation to be cultivated and analyzed at the laboratories of microbiology of faculty of medicine, cairo university
Effect of Neem and NaOCl on Postoperative Pain and Amount of Endotoxins
PainPostoperative Pain3 moreThe aim of this study is to compare the effect of Neem (azadirachta indica) and 2.5% sodium hypochlorite as root canal irrigants on the intensity of post-operative pain and the amount of endotoxins in necrotic teeth.
Perform Necrotic Cavity Lavage or Not After Debridement of Infected Pancreatic Necrosis
Pancreatitis,Acute NecrotizingPancreas NecrosisThe infected pancreatic necrosis (IPN) should be treated by debridement and drainage. In recent years, the results of clinical research show that minimally invasive debridement such as video-assisted (laparoscope, nephroscope, endoscopy, etc.) and total laparoscopic debridement can significantly improve the prognosis of IPN patients. After a long period of clinical practice, laparoscope-assisted debridement was selected as the main surgical method in our center. In many large-scale clinical studies, patients after surgery underwent necrotic cavity lavage (such as small omental sac lavage, retroperitoneal space lavage, peripancreatic lavage, etc.), but its necessity and clinical significance were not clearly stated in the guidelines. At present, the clinical research mainly focuses on the improvement of minimally invasive debridement, and less on the necessity of lavage. In the past, necrotic cavity lavage was performed in IPN patients, but long-term clinical observation showed that lavage may lead to spread of infection and increase the incidence of lower extremity venous thrombosis which is not accorded with ERAS(Enhanced Recovery After Surgery). Therefore, since 2012, our center has stopped necrotic cavity lavage for IPN patients after debridement. We retrospectively analyzed the therapeutic effect from February 2014 to August 2017 and found that even without necrotic cavity lavage, better therapeutic effect could be achieved. Meanwhile it can simplify the operation process and avoid infection spread. This treatment method provides a new idea. However, it is a retrospective study not a randomized controlled trials(RCT) which is low effectiveness of proof. Therefore, we design this RCT to verify the necessity of necrotic cavity lavage after laparoscope-assisted debridement for patients with infected pancreatic necrosis.
