Start date: June 7, 2018
Phase:
Study type: Observational [Patient Registry]

Background: The exit strategy after ureteroscopy for stone treatment remains a topic for discussion. Current EAU guidelines on urolithiasis state that postoperative stenting is indicated in patients at increased risk of postoperative complications. Stenting is not considered necessary in all other cases, and after uncomplicated procedures. Objective: To analyse the postoperative ureteral stenting strategy in clinical practice looking at the indication, type of stents used and the duration of stenting after ureteroscopy for stone treatment. Furthermore, the investigators will examine in what setting the stents are being removed postoperatively. Study design: This study is a prospective, observational, international, multicentre registry study executed by uCARE. Study population: All patients >18 years with a ureter or renal stone who are planned for ureteroscopic treatment by semi-rigid and/or flexible ureteroscopy are eligible for this study.

NCT ID: NCT03555045 Recruiting - Clinical trials for Horizontal Strabismus With High AC/A Ratio

The Effect of Slanted Recession of Horizontal Muscle on Horizontal Strabismus With Abnormal Accommodative Convergence /Accommodation Ratio (AC/A)

Start date: February 1, 2017
Phase: Phase 2/Phase 3
Study type: Interventional

Different methods was tried to treat high AC/A strabismus cases;such as prescription of bifocal glasses in esotropia,recession of horizontal muscles with posterior fixation sutures,more recession than needed for far deviation(augmented recession),recession and pulley fixation and slant recession. Different results was reported for any type of above methods. In recent studies,slanted recession was applied for high AC/A in esotropic cases and success rate of 67% was reported.but there was no unanimity for procedure of choice. Since slant recession method is simpler and has low side effect than the other methods,therefore in this study the investigators want to peruse the outcome of this method on high AC/A horizontal strabismus.

NCT ID: NCT03551834 Recruiting - Glaucoma Clinical Trials

Ahmed Glaucoma Valve Implantation; Graft-Free Short Tunnel Small Flap Versus Scleral Patch Graft

Start date: January 20, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

Glaucoma implants have been used for refractory glaucoma and are gaining popularity as a primary procedure in selected patients. In order to prevent tube erosion, a biologic material such as pericardium, cornea, and sclera is used as coverage over the tube. Despite this preventive measures, patch graft thinning and silicon tube exposure are still a serious complications and may occur in 1%-7% of eyes after glaucoma implantation. In this study we used a novel technique named short tunnel small flap (STSF) by tunneling the sclera without using any biological material . efficacy and safety of this technique is comparing with conventional scleral patch graft. This randomized clinical trial, was performed at the Glaucoma Clinic of Labbafinejad Medical Center, Tehran, IRAN from September 2015 to January 2017 . The study was approved by the ethics committee at the Ophthalmic Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran and followed the tenets of the Declaration of Helsinki. After explaining all therapeutic options and their side effects, the written consent form was obtained from all patient. 80 eyes of 80 patients with refractory glaucoma underwent AGV implantation by short tunnel small flap technique (group1) or scleral patch graft (group2) randomly. Primary outcome measure is Intraocular pressure(IOP) and Tube exposure, and secondary outcome measure is success rate that is defined as intraocular pressure (IOP) > 5 mmHg, ≤ 21 mmHg, and IOP reduction ≥ 20% from baseline at two consecutive visits after three months, no reoperation for glaucoma. Outcome measures are compared at 1, 3 , 6 and 12 months postoperatively.

All patients were undergone phacoemulsification surgery at Torfeh Eye Hospital between September 2015 and January 2017. To evaluate the prophylactic effect of ketorolac tromethamine topical eye drop, all cases were asked to apply it one day before the s:surgery in each 8 hours and continue it for 4 weeks after the surgery. Controls were not received placebo. All study population were examined using Snellen visual acuity chart, enhanced depth imaging optical coherence tomography (EDI-OCT). All patients were followed at 6, 12 and 24 weeks after the cataract surgery.

NCT ID: NCT03541109 Not yet recruiting - Clinical trials for Acute Coronary Syndrome

A Polypill for Secondary Prevention of Ischemic Heart Disease

Start date: August 2018
Phase: Phase 3
Study type: Interventional

Cardiovascular diseases (CVD) are the leading cause of mortality and morbidity worldwide. The most important aspect of CVD secondary prevention is adherence to guideline-indicated pharmacological therapy which globally remains low. In previous studies, a Polypill containing fixed dose combination of essential drugs have improved patient adherence to these drugs. The effect of such a strategy on pharmacological therapy uptake, cost-effectiveness, and CVD recurrence in our setting will be assessed in this study. Participants hospitalized in three referral hospitals in Isfahan, Iran because of an acute coronary syndrome (ACS) or revascularization procedure (PCI or CABG) will be randomized to either receiving Polypill or four components of Polypill separately. Patient recruitment will be carried out at the time of patient discharge from the hospitals.

Start date: May 30, 2018
Phase: N/A
Study type: Interventional

Metabolic syndrome is a public health challenge that includes a range of conditions including abdominal obesity, dyslipidemia, hyperglycemia, and hypertension. The syndrome is associated with an increase in the risk of Cardiovascular disease and death. Curcumin is a very active compound obtained from turmeric root. Curcumin has antioxidant and anti-inflammatory effects, and is also involved in the regulation of several signaling pathways. Since curcumin powder has low bioavailability, fast metabolism and low absorption, nanomicielle curcumin will be used in this study. Therefore, this study is planned to determine the effects of supplementation of nanomicielle curcumin on oxidative stress, systemic inflammation, adiponectin in serum and NF-kB in peripheral blood mononuclear cells in patients with metabolic syndrome.

NCT ID: NCT03499886 Recruiting - Procedural Sedation Clinical Trials

Low-Dose Intravenous Ketamine Bolus Versus Conventional Technique

Start date: January 17, 2017
Phase: Phase 2/Phase 3
Study type: Interventional

Abstract Background: Ketamine has been introduced as one of the most common drugs, administered to sedate children for different painful procedures in the emergency department (ED) but administration in higher dosage causes some severe complications. Thus, the aim of this study was to evaluate the effect of low-dose intravenous ketamine bolus versus conventional injection for reduction of upper and lower extremity fractures in children. Materials and Methods: In this randomized clinical trial, 198 participants with upper and lower extremity fractures were enrolled. The participants were divided randomly into two groups. In the intervention group, ketamine 1% was administered rapidly at a dose of 0.5 mg / kg (within 5 seconds), and in the control group, ketamine 1.5 mg / kg was slowly injected for 30 to 60 seconds. Then outcomes such as sedation depth and complications were measured for every two minutes and satisfaction of participants and physicians were recorded. Results: Results showed that the successful sedation rate in the low dose ketamine group was significantly lower, as compared to the control group (7% vs 100%) (p<0.001). Moreover, In terms of duration of drug effect and of recovery, the low dose ketamine group were significantly lower compared with the group receiving higher dosage of ketamine (p<0.05). Furthermore, the sedation depth based on Wisconsin Sedation Scale was significantly higher, in the low dose ketamine group compared to the other group. By evaluating different complications, we found that the rate of neurological (20.4 % vs 5%) and physiological (10.2% vs 2%) complications in the control group was significantly higher compared to the group receiving low-dose ketamine (p<0.05).

NCT ID: NCT03488836 Recruiting - Clinical trials for Endodontically Treated Teeth

Evaluation the Post Operative Pain of Endodontic Treated Molar Tooth With Race and Reciprocal Systems Among Bandarabbas Patients in 2017

Start date: May 2, 2018
Phase: Phase 2/Phase 3
Study type: Interventional

extrusion of infected dentin into the periapical tissue has been suggested as a major source of pain after endodontic treatment. Although debris extrusion is an inevitable finding even when instrumentation is limited to the confines of the canal, different armamentarium seem to be associated with different amounts of debris extrusion. Studies on the effect of various rotary files on post-endodontic pain are very few and have yielded conflicting results with some favoring full-sequence and others leaning towards reciprocal rotary systems. This study aims at assessing the intensity of post-endodontic pain following two different rotary systems, Reciproc and race. Methods: in this single-blind, parallel-grouped randomized clinical trial a total of 150 otherwise healthy patients aged between 20 to 50 years old with a pulpal status of irreversible pulpitis for one tooth in the upper or lower molar region were analyzed. A clinician performed the endodontic treatment in two groups, a group instrumented using race and a third group with instrumentation performed using Reciproc rotary systems.
