There are about 11256 clinical studies being (or have been) conducted in Egypt. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
In the stomach, the ghrelin-containing cells are more abundant in the fundus than in the pylorus originally termed X/A-like cells. These X/A-like cells account for approximately 20 % of the endocrine cell population in adult oxyntic glands. Ghrelin enhances the secretion of growth hormone, the stimulation of appetite and food intake, the modulation of gastric acid secretion & motility and the endocrine and exocrine pancreatic secretions.
Background: Dental lasers and electrosurgical devices have been introduced a long time ago. However, limited studies are available concerning their use in the second stage of implant surgery, with the conventional surgical technique being the standard of care. Aim of this study: To evaluate clinically and radiographically soft and hard tissue healing associated with the use of electrosurgical and laser devices and compare them with conventional surgical techniques during second-stage implant surgery. Plan of the study: A randomized controlled clinical trial. The sample size will include patients who have an implant already placed and ready for second stage surgery recruited from the patient pool at the outpatient clinics. Materials and Methods: Patients will be randomly allocated into the three groups. In Group (A) implant will be exposed using the conventional surgical exposure techniques with a tissue punch, the cover screw will be removed, and the healing abutment placed. In group (B) implant will be uncovered using a diode laser (940nm) in contact type with a continuous mode at a power of 1.5 watts, the laser tip will be used in a circular motion to create a small opening which will be increased till large enough to expose and remove the cover screw and place the healing abutments. In group (C) the monopolar electrosurgical device will be used in the same way as the laser tip with additional care avoiding contacting the implants during exposure. The outcome: will be soft tissue healing and crestal marginal bone loss around implants. Soft tissue healing will be assessed on the operative day, 2 weeks, and 4 weeks using Landry index. Crestal bone loss will be assessed using a standardized periapical x-ray at baseline and after 1 month with periapical x-ray.
Breast surgeries are common operative procedures that require appropriate postoperative analgesia.
The aim of this research is to evaluate the safety and efficacy of green tea in obese pediatrics with prediabetes versus the metformin therapy alone that is given to these patients. The primary outcome is to tackle the insulin resistance in these patients to prevent the deterioration of prediabetes to type 2 diabetes. The assessment of the effect on insulin resistance by using homeostatic model assessment for insulin resistance (HOMA-IR levels) as well as the effect on blood glucose levels and glycated hemoglobin. The other primary outcome is to observe the effect of the intervention on the lipid profile, leptin and adiponectin. The secondary outcome is to determine the effect of green tea on the oxidative and inflammatory markers and to evaluate its safety and efficacy. The study design is prospective parallel randomized open- label controlled interventional clinical trial that will be conducted in El-Demerdash hospital children's endocrinology unit. The patients who fit the inclusion criteria will be educated about the study protocol and will be required to sign a written informed consent. The inclusion criteria are: children whose age is between 10 to 18, whose HOMA-IR >2.5, BMI >= 95th percentile and have no sensitivity towards green tea and willing to sign informed consent. Patients who have causes of endogenous obesity will be excluded and those who have any other comorbid conditions. All patients fulfilling the inclusion criteria will be randomly assigned by simple randomization into either Group 1 (Control group): Consists of 45 patients who will receive their conventional therapy which is Metformin 500 mg film coated tablets (Glucophage). Group 2 (Interventional group): Consists of 45 patients who will receive Green Tea 300 mg (Green tea 300 mg film coated tablets Mepaco Egypt) thrice daily + Metformin 500 mg film coated tablets (Glucophage). At baseline the following parameters will be collected during patients' interview and from patients' files: Demographic data as age, sex, weight and height (BMI), family history, medical history, medication history. Thyroid functions (TSH/T3): to rule out any other endocrine causes of obesity. Cortisol levels (am and pm): to rule out any other endocrine causes of obesity. The following laboratory' measurements will be tested at baseline and at the end of study (4 months): Complete Blood Picture, fasting blood glucose and postprandial blood glucose, fasting plasma insulin, homeostatic model assessment for insulin resistance, homeostatic model assessment for β-cell function, lipid profile, leptin, adiponectin, malondialdehyde, liver functions, kidney functions, c-reactive protein, nuclear factor kappa beta. Patients will be educated about the side effects and/or adverse effects of green tea, where safety and tolerability will be monitored by reporting the incidence of any side effect and /or adverse effect such as liver problems, yellowing of the color of skin or white of the eyes or stomach pain. Participants will be followed up during the study period every 2 weeks through clinic visits and by phone in order to assure compliance as well as monitoring of incidence of any side/adverse effects and informing the patients who to handle it.
in our study, we will investigate the impact of adding dexmedetomidine to bupivacaine for the potency of the obturator nerve block and prevention of the postoperative pain associated with transurethral surgery in comparison of obturator nerve block with bupivacaine alone
The purpose of this randomized controlled clinical study was to evaluate the locator and TITACH attachments used for retaining mandibular 2-implant overdentures regarding retention , bite force and implant marginal bone loss after overdenture insertion
The purpose of this study is to compare the effect of Local Muscle Vibration versus Muscle energy technique on pain intensity, pain pressure threshold, functional disability, and innominate angle tilt in SIJD. This study will try to answer the following question: What is the effect of Local Muscle Vibration compared to Muscle energy technique on pain intensity, pain pressure threshold, functional disability, and innominate angle tilt in SIJD?
The goal of this clinical trial is comparing the efficacy of custom-made zirconia sheet versus Polytetrafluoroethylene as a non-resorbable barrier in maxillary alveolar ridge augmentation. The main question it aims to answer are: 1. Is custom made zirconia sheets are valuable as a non-resorbable membrane in guided bone regeneration? 2. Does it have any adverse effects on the surrounding tissue? 3. the accuracy of using two software in the designing of the zircon membrane? - Participants will be selected according to the inclusion criteria of the study, having a defect in the upper jaw that prevent rehabilitation of the jaw. - Participant will undergo a surgical procedure for placement of bone graft and the non-resorbable membrane. Researchers will compare between two groups which differ only in the used membrane. a group where the researchers will place custom made zirconia sheet versus a group where the researchers will place Polytetrafluoroethylene.
