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.
The aimof this study is to observe the effect of intraoperative magnesium infusion on peri-operative pain and postoperative cognitive functions in adult patients after elective pelvi-abdominal surgeries.
Two different Fluoride varnish systems(Fluoride varnish containing Chlorhexidine and Cetylpyridinium Chloride (CPC) and conventional fluoride) will be applied to high caries risk patients to assess their clinical effects on plaque accumulation and plaque bacterial count .
Stress perfusion CMR has recently considered as one of the methods of choice for establishing the diagnosis of CAD based on its high diagnostic accuracy, lack of ionizing radiation as well as its ability to simultaneously assess the cardiac function, myocardial perfusion, and viability, however, there are some concerns on its suitability for assessment of myocardial perfusion in patients after coronary artery bypass graft surgery who suffer from recurrent angina. The study of hemodynamic forces offers a promising tool for further understanding of the interplay between the myocardium and blood as well as the mechanisms of cardiac filling. This work represents a retrospective follow up study of CMR data, available on CMR-database, from 112 patients with previous coronary artery bypass grafting (CABG) performed around 10 years before the initial CMR examination. The study subjects underwent stress CMR testing; using both stressors; dobutamine and adenosine (done on two separate occasions). Injection of gadolinium contrast medium for late gadolinium enhancement was done with adenosine stress testing for late gadolinium enhancement (LGE). Offline analysis of these data will be done with the use of dedicated software for assessment for myocardial ischemia together with quantitative measurements of the hemodynamic forces with the help of dedicated software (QStrain version 1.3.0.79; Medis, Leiden, the Netherlands).
Since abnormal keratinocyte (KC) proliferation and differentiation as well as defective E cadherin expression were reported in vitiligo lesions, the investigators set to study the potential efficacy of combining Retinoids, which are known to improve KC proliferation and differentiation and increase the expression of adhesion molecules, with narrowband UVB in the treatment of vitiligo.
Descriptive observational cross sectional study Outpatient at faculty of dentistry Cairo university pediatric dentistry department clinic with midline diastema and fully erupted canines will be examined and assess type of frenal attachment to see if correlation present or not

The method of transcatheter aortic valve implantation (TAVI) introduced in 2002 by Alain Cribier et al. has offered new prospects for patients with severe aortic stenosis and multiple comorbidities, who are at high operative risk(1). The PARTNER series of randomized controlled trials has firmly established the role of TAVI with the balloon-expandable Edwards Sapien valve in patients with severe symptomatic aortic stenosis (AS) at prohibitive risk of surgery (PARTNER IA), high risk for surgery (PARTNER IB), and intermediate risk for surgery (PARTNER 2).(2) Also PARTNER 3 and Evolut Low Risk trial strongly suggest that TAVI is not only a suitable alternative and may be superior to surgical aortic valve replacement ( SAVR) in low-risk patients.(2) The accurate determination of the size of the implant is dependent on pre-procedural imaging. Annular measurements are important in the TAVI as inaccurate estimation can lead to complications e.g paravalvular leakage .(3) Transthoracic echocardiography (TTE), transoesophageal echocardiography (TOE), multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) have been extensively studied with respect to pre-procedural aortic annular sizing.(3). However, even with some of the evidence returning a discrepancy in annular measurements between techniques, the literature to date does not clarify whether TOE undersizes inappropriately or appropriately with respect to MDCT.(3) In a recent study, 29.5% of patients would have been deemed ineligible for TAVI because of overestimation of annular measurements by MDCT, a figure reduced to 1.3% with the use of TOE (4) In a recent small retrospective study, TOE, MDCT and MRI all performed comparatively well with device sizing. (5) Balloon aortic valvuloplasty (BAV) dilatation before TAVI is considered a mandatory procedural step in the early years of TAVR. BAV is used to confirm annular sizing and to enhance trans-catheter heart valve (THV) deliverability.(6) However till now there is no comparison of annular measurement by 2D transesophgeal echocardiography with balloon sizing.
The treatment of uterine niche ranges from clinical management with expectant or pharmacological treatment, surgical treatment. Approaches for repair include Laparotomy, laparoscopy , hysteroscopy , vaginal. The decision to treat takes into consideration the size of the defect, presence of symptoms, secondary infertility and plans of pregnancy. All of the approaches have its merits and debates. There is ongoing debate regarding the best surgical approach to managing this condition. To date no randomized controlled trials have been published to settle this debate. Our study aim is to to evaluate which surgical approach is a preferable option, this study will be conducted to compare the Laparoscopic and transvaginal approaches in several regards, including, operation time, blood loss, perioperative complications, hospital stay length, postoperative increase in residual myometrial thickness during follow-up , clinical efficacy(percentage of patients who subject improvement of symptoms)
Pregnant women at 32-36 weeks gestational age with sure gestational dating (based in both last menstrual period and dating ultrasound) and otherwise normal singleton pregnancy will be recruited. Ultrasonographic estimation of gestational age using combined transcerebellar diameter and placental thickness will be compared to the actual estimated gestational age.
This study investigate the effect of pre-operative ultrasound guided stellate ganglion block with local anesthetic on the frequency of neuropathic pain syndromes in the first 6-month post cancer breast surgeries with axillary dissection.
