Clinical trials

The goal of this clinical trial is to evaluate the optimal drug therapy of HCV in CKD Patients different stages with or without compensated cirrhosis. The main questions it aims to answer are: outcome measure 1: Efficacy of the treatment by the assessment of sustained virological response (SVR12) following 12 weeks after the last dose HCV RNA drop to undetectable levels. outcome measure 2: Safety of the treatment by comparing the biochemical parameters before and after treatment. If there is a comparison group: Researchers will compare biochemical parameters of the participants before and after treatment to see if there is any decline in the general health. Participants will be divided to two groups according to their kidney status depending on their GFR, Group 1: 25 CKD Patients with eGFR more than 30ml/min with HCV infection and will receive Sofosbuvir and Daclatasvir regimen for 12 weeks, Group 2: 25 CKD Patients with eGFR less than 30ml/min with HCV infection and will receive Paritaprevir, Ombitasvir, Ritonavir and Ribavirin for 12 weeks.

Major depressive disorder (MDD) is one of the most common psychiatric disorders with serious socioeconomic consequences on daily life and health care costs. Despite the advent of newer antidepressants that target monoamine pathways, nearly 50% of patients have no response to first-line antidepressant therapy. Thus, a combination of medications with different strategies at the beginning of treatment could provide further therapeutic benefits to MDD patients.

Endoscopic retrograde cholangiopancreatography (ERCP (, a key tool that is used in diagnosis and treatment of pancreato-biliary diseases. Post-ERCP pancreatitis (PEP) is the most common and serious complication that can occur following this procedure and can lead to significant morbidity and mortality. A variety of patient-related and procedure-related factors have been associated with higher rates of PEP.

This study compares two types of surgical guides used during immediate dental implant placement in the upper front teeth. One guide is a conventional static surgical guide, while the other is a modified SocketFit static surgical guide designed to improve stability after tooth extraction. The purpose of the study is to determine whether the SocketFit guide improves the accuracy of implant placement.The findings may help improve the precision and predictability of immediate dental implant treatment in the anterior esthetic zone.

This study will be a randomized controlled parallel study that will be conducted on 66 patients with active rheumatoid arthritis who will be diagnosed with RA according to American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR, 2010). The patients will be recruited from Outpatient Clinic of Rheumatology, Physical Medicine, Rheumatology and Rehabilitation Department, Tanta University Hospital, Tanta, Egypt. The study duration will be 3 months. The patients will be randomized into three groups: \- Group 1 (control group): will include 22 patients who will receive the conventional therapy for RA for 3 months. \- Group 2 (diosmin group): will include 22 patients who will receive the conventional therapy for RA plus 1000 mg diosmin once daily for 3 months. \- Group 3 (rebamipide group): will include 22 patients who will receive the conventional therapy for RA plus 100 mg rebamipide three times daily for 3 months.

This crossover clinical study aims to evaluate the influence of three different intraoral scanning techniques on the scanning accuracy and passive fit of mandibular implant-supported fixed detachable prostheses in completely edentulous patients. Each participant will undergo digital implant scanning using three methods: splinted scan bodies, horizontal non-calibrated scan bodies (IO Connect), and auxiliary geometric devices.

This randomized crossover clinical trial aims to evaluate the effect of different three-dimensional (3D) printing orientations and layer thicknesses on the trueness, dimensional accuracy, and patient satisfaction of maxillary complete dentures in completely edentulous patients. Each participant will receive two maxillary 3D-printed complete dentures fabricated using the same printing orientation (0°, 45°, or 90°) with two different layer thicknesses (50 μm and 100 μm) in a crossover sequence. The study will compare the influence of these printing parameters on denture accuracy and patient-reported outcomes to identify the optimal 3D printing settings for complete denture fabrication.

The aim of this study is to compare the analgesic efficacy and safety of ultrasound-guided midpoint transverse process block versus ultrasound-guided erector spinae plane block in patients suffering from thoracic herpes zoster pain.

The primary goal of this cross-sectional study is to assess risk factors/predictors for dysphagia in RA. The secondary goals include demonstrating whether flexible fiberoptic pharyngolaryngoscopy can detect joint-affection-induced dysphagia in patients with rheumatoid arthritis (RA) and whether both oropharyngeal and esophageal dysphagia are present among these patients. The main questions it aims to answer are * What are the predictors that are associated with dysphagia via flexible fiberoptic pharyngolaryngoscopy in rheumatoid arthritis patients? * Whether flexible fiberoptic pharyngolaryngoscopy can detect joint-affection-induced dysphagia in patients with RA? * Whether both oropharyngeal and esophageal dysphagia are present in patients with RA?

the goal of this study is to evaluate the efficency of different activation techniques in removal of intracanal medication using cone beam computed tomography analysis

To assess the effect of Febuxostat on clinical outcomes and biomarkers of oxidative stress and inflammation in patients with conservatively managed intracranial hemorrhage.

gastric functions especially gastric emptying is still debatable after anti reflux surgery in children. this study aims to predict the best procedure associated with good gastric emptying time and gastric functions following anti reflux procedure when compared two procedures, Nissen fundoplication vs Hil snow fundoplication in multicenter pediatric surgery tertiary hospitals.
