The purpose of this study is to compare the effect of lumen-apposing metal stent (LAMS) and double pigtail plastic stents (DPPSs) on the drainage of pancreatic walled-off necrosis (WON), mainly to observe the efficacy and safety of LAMS for WON.
the investigator intended to study the effect of laser versus ultrasonic in activation of irrigation in post operative pain of patients have a symptomatic necrotic teeth
The primary objective is to assess if discontinuation of anti- tumor necrosis factor alpha (TNF) treatment in ulcerative colitis patients in sustained clinical remission, with the option to restart treatment in the case of relapse, is non-inferior to continued anti-TNF treatment. Secondary objectives are to assess the efficacy and safety of restarting anti-TNF treatment after a relapse
The aim of this prospective in vivo randomized clinical trial to evaluate influence of combination of calcium Hydroxide (CALCIPAST Paste, Poland) and chlorhexidine Gel 2% (Gluco-Chex 2%, Cerkamed, Poland) in comparison to calcium hydroxide paste (CALCIPAST Paste, Poland) as Intracanal Medication on post operative pain (incidence, degree, duration) and reduction of bacterial endotoxins (quantitative) after endodontic treatment in single rooted necrotic teeth. According to the inclusion criteria the patients enrolled in the study and allocated randomly into three groups either combination of calcium hydroxide paste intracanal medication with 2% chlorhexidine gel. (group A) or calcium hydroxide paste intracanal medication only (group B) or mechanical preparation without intracanal medications (group C) the endodontic treatment is done at two visits. The samples of endotoxin divided into three groups: after access (S1), after mechanical instrumentations (S2), after removal intracanal medication (S3), all samples taken by a sterile paper points introduced in the root canal for the working length for 60 seconds. firstly the patient's medical and dental history is taken. the patients assign on informed consent. and then anaesthetized and access cavity performed and root canal preparation is done by Revo-s system then irrigation and intracanal medication placement inside to canal. the patient's record the post operative pain in sheet with NRS after 4, 24, 48 hours and 2 weeks after first visit. the operator will recall the patient to check the records second visit After 2 weeks from application of ICM, rubber dam will be applied then removal of the temporary dressing, then a sterile paper point (S3) will be introduced into the canals after irrigation and removal of the remnants of the intracanal medicament with the saline solution. - Removal of the paper sample to determine the endotoxin concentration. - The canals will be obturated by single cone technique using gutta percha point tapered 0.4% (Gutta percha point, Revo-S MicroMega CO., LTD, France) corresponding to the final apical size of the file and the root canal sealer will be resin sealer (Adseal, META BIOMED CO., LTD, Korea). - Pain will be assessed by numerical pain rating scale (NRS) after 14 days from the first visit (at the day of the Obturation) before the beginning of Obturation.
To evaluate clinical efficacy and safety of a novel lumen-apposing FCSEMS for EUS-guided transenteric drainage of PFC or of biliary tree including GB
To evaluate the incidence and severity of postoperative pain after root canal therapy of necrotic teeth in one appointment versus two appointments using Protaper next instrument.
The investigators,according to the eligibility criteria,plane to choose 80 elderly anticipates who will undergo selective hip replacement surgery.This participants will be randomly divided into 2 groups:light anesthesia depth group(L Group) and deep anesthesia depth group (D Group).Before anesthesia induction,each participant will be given lumbar plexus and sciatic nerve block in order to control pain of interoperative and postoperative.During operation period,the L Group will be kept in light anesthesia depth(BIS:50-60),while the D group will be kept in deep anesthesia depth(BIS:35-45)--The BIS values in the range of 30-60 have been recommended in general anesthesia.After operation,a PCIA(patient controlled intravenous analgesia) analgesia pump will be given to each participant to control postoperative pain. The investigator will evaluate the mental state of participant with MMSE(mini-mental state examination) before surgery and review each participant with a CAM-CR for 3 days after surgery to assess the situation of postoperation delirium.intraoperative awareness,postoperative pain will also be investigated in postoperative days 1, 2, 3.
This study aims to assess the technical performance of Tc-99m tetrofosmin SPECT as compared to F-18 FDG PET for the differentiation of radiation necrosis from glioma relapse and to obtain estimates of diagnostic accuracy for Tc-99m tetrofosmin SPECT and F-18 FDG PET in an intra-individual comparison.
Comparing the postoperative flare ups and pain after adding the XP Endo Finisher to the final irrigation protocol on necrotic mandibular premolars.
