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.
All patients will undergo in vitro fertilization. Serum 25 (OH) D samples will be collected within1 week before oocyte retrieval. Whole blood specimens will be collected in serum separator tubes using acceptable medical techniques to avoid hemolysis. Ultrasound guided fresh embryo transfer will be performed on day 5 after fertilization. clinical pregnancy will be confirmed by observation of intrauterine sac visible on ultrasound performed 4-5 weeks after embryo transfer.
Beta Thalassemia is a major public health problem in Mediterranean countries.In Egypt, it is considered as the most common chronic hemolytic anemia.one of the major complications in this inherited disorder is iron overload which lead to oxidative stress and tissue damage. Regarding toxic effect of iron overload on liver, hepatomegaly is one of the most findings that resulting from hemosiderosis, extra medullary hematopoiesis, transmitted hepatitis B and C and cirrhosis. A lot of studies have been carried out recently to study the beneficial role of metformin in non-diabetic patients of different disorders as non-alcoholic fatty liver disease (NAFLD).Among several studies, it's demonstrated that metformin significantly improved insulin resistance, aminotransferase levels and liver morphology. The role of metformin in these studies is mainly thought to be antioxidant and anti-inflammatory effects. However, the role of Metformin on hepatic function in different populations with the same mechanism of liver injury should be further investigated. This clinical trial will be carried out on 60 patients with beta thalassemia major receiving regular blood transfusion and iron chelating therapy, either HCV positive or negative patients. They will be randomly distributed into either control group (group 1, n=30) receiving blood transfusion and taking iron chelating therapy or treatment group (group 2, n=30) receiving blood transfusion and taking iron chelating therapy along with metformin tablets (500 mg/twice daily) for 6 months.
The aim of this study is to determine the effect of administering antenatal steroids in term fetuses on the blood flow in the fetal pulmonary artery, and to correlate these findings with clinical data obtained after birth documenting respiratory disorders.
The purpose of this study is to assess the effectiveness of hysteroscopic tubal application of Iso Amyl-2-cyanoacrylate in occluding uterine tubes of infertile women with hydrosalpinx, which would make it an easy approach for occluding tubes with hydrosalpinx prior to IVF.
Investigators aim to investigate the effect of elimination of blastocoelic fluid by creating a large hole in the zona pellucida at the cellular junction of the trophectoderm cells located far away from the inner cell mass with a laser pulse before vitrification.
Ischemic stroke accounts for the majority of stroke cases and constitutes a major cause of death and disability in industrial world. Inflammation has been reported to constitute a major component of ischemic stroke pathology. The brain responds to ischemic injury with an acute andprolonged inflammatory process. Few studies have investigated the relationship between acute biomarkers of inflammation and functional outcome following stroke
Platelet-rich Plasma Use as Prophylactic of Post-operative Low Back Pain Following gynecological surgery.
Aim of the work is to compare the results of femtosecond assisted LASIK and small incision lenticule extraction (SMILE) as regards safety, efficacy and predictability. As a secondary outcomes , the investigators will compare the results of both techniques on corneal biomechanics, dry eye measures, corneal asphericity and higher order aberration.
Both patient and staff safety are of major importance during the procedure of fibreoptic bronchoscopy. Patient safety depends partly on adequate disinfection of instruments and accessories used as well as careful monitoring during the procedure.
Ultrasound guidance has been established as an effective and safe method during insertion of internal jugular vein catheter.. Needle visualization during advancement toward the vein has a great impact on both safety and success of the procedure. Clinicians have adopted variable techniques to increase needle visualization including changing needle- probe relation (in-plane vs. out-of-plane), or using specific ultrasound needles The angle between the inserting needle and the probe lying on patient skin affects both the distance to the vein and the length of the needle part travelling through the us beam
