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.
Intraocular pressure (IOP) is maintained by a balance between aqueous production and outflow with an imbalance leading to elevated eye pressure. Very high levels of IOP will subject retinal cells to mechanical stress. In addition to mechanical injury, IOP elevation can impair ocular blood flow reducing perfusion pressure to retinal neurons. Long-term vascular and mechanical stresses can produce further injury at the optic nerve. Elevated intraocular pressure (IOP) or ocular hypertension (OHT) is the only well-established modifiable risk factor for primary open-angle glaucoma (POAG), the most common form of glaucoma. Glaucoma is a class of optic neuropathy. It is main leading cause of blindness. Glaucoma is classified on the basis of anatomic features as open angle (where the anterior chamber angle of the eye remains open) and angle-closure (with closure of the anterior chamber angle). Glaucoma is considered primary if the eye has no preexisting disease. Secondary forms of glaucoma are caused by various ocular or systemic diseases such as pigment dispersion syndrome and ocular trauma. It seems reasonable to consider that a longer duration of diabetes mellitus (DM) with a prolonged insult to the retina and optic nerve via vascular, glial, and neuronal factors would be associated with a higher risk of OAG.
Breast cancer is the most common cancer of women. Surgery for early breast cancer includes axillary lymph nodes staging. Axillary surgery may lead to intractable complications like permanent arm swelling. Axillary sentinel lymph node biopsy (SLNB) has been introduced to minimize the incidence of these complications. Several methods are routinely used for identification of the sentinel node during operation. Some of these methods necessitate facilities that are not universally available; specially in countries with limited resources. In its simplest form, SLNB using the methylene blue dye technique has an identification rate of 88-94%. If the sentinel node can not be identified, full axillary dissection may be required and the risk of arm swelling is increased. The objective of this study is to maximize the identification rate of the sentinel node thus avoiding the need for extensive axillary surgery. The investigators assumed that preoperative tattooing of the suspicious lymph node during ultrasonographical imaging may help the surgeon in localizing the sentinel lymph node. In this study, the sonographer will perform preoperative tattooing of the suspicious node. The surgeon will perform SLNB by the methylene blue dye. The sensitivity of ultrasonographical tattooing relative to SLNB will be calculated. The study will determine if the tattooing technique may localize additional nodes that are missed by the methylene blue.
The investigators hypothesize that low energy shock wave therapy (LESW) might induce damage to the tumor tissues of non-muscle invasive bladder cancer (NMIBC), so they could be ablated and detached from the surface. The patients who are suffering from NMIBC will be randomly allocated into two groups: The first group (control group): 25 patients will be exposed to sham treatment before transurethral resection of bladder tumor (TURBT) without using LESW therapy. The second group (LESW group): 25 patients will be exposed to LESW therapy before TURBT. The apoptotic effect of LESW will be studied via histopathological examination and molecular studies of the resected bladder tissues. The patients will receive intravesical chemotherapy or BCG immunotherapy and they will be followed up at outpatient clinic for two years by MRI, outpatient cystoscopy and cytology to identify the recurrence and progression rate of NMIBC.
the investigatots hypothesized that by injection a larger volume and higher concentration of local anesthetic in lumbar erector spinae plane block could result in successful anesthesia in patient undergoing lower limb vascular surgery. ultrasound-guided lumbar erector spinae plane block in patient undergoing lower limb vascular surgery with higher concentration of local anesthetic to asses it is efficacy as a sole anesthetic technique, it is safety and efficacy in maintaining intraoperative hemodynamics, intra and postoperative pain control .
The aim of the study is to evaluate the ability of ulna length to predict accurate protective lung tidal volume in Egyptian people in reference to their standing height.
OS is an important pathogenetic mechanism for the development of T2DM and its complications. Oxidative stress is an imbalance of the generation of free radicals or known as reactive oxygen species (ROS) and reactive nitrogen species [RNS]) and their neutralization by the antioxidant mechanisms. Increased levels of ROS and RNS lead to damage of lipids, proteins, and DNA, ultimately causing the destruction of the islet cells of pancreas through apoptosis . Elliptical trainer device is a relatively new modality of exercise and is advertised to be superior to a treadmill because of the low joint impact and the more reasonable costs of an elliptical trainer compared to a treadmill . Additional quantative research is needed to further evaluate the effectiveness of elliptical trainers and the physiological and perceptual responses to the machine Electroacupuncture (EA) is a treatment form of traditional acupuncture in which small electrical currents are passed through needles inserted into the subject's skin using EA stimulator. It seems to have more acceptable results and effects on many important clinical applications and medical research sets .
To encourage the application the recommended positions of the World Health Organization during normal childbirth and its effect on maternal and labor outcomes
Using a smart phone while adopting a poor posture can cause various physical problems. The neck and shoulders are particularly vulnerable to pain due to smart phone use, with the muscles showing a high level of muscle fatigue, resulting in exhaustion and pain, Therefore, determining the durable time to use the smart phone will protect us from abnormal posture and protect our muscle and ligaments. Furthermore avoid the incorrect position of use smartphone position.
The study is a Diagnostic accuracy study that determining the accuracy of assessing the gingival biotype and some other anatomic parameters,including (crown width / crown length ratio, attached gingival width, labial bone thickness and papilla volume) by different methods :1- probe transparency, 2-transgingival probing, 3-cone beam computed tomography, 4-intraoral digital scanning, 5-extraoral digital scanning
