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.
Parkinson's disease is the second most common neurodegenerative disease affecting about 1-3% of population above 60 years. Recently, non-motor symptoms are getting more attention in PD management. The pattern of PD onset and clinical course differ from one population to another. Many studies have been conducted to determine the clinical profile of PD in populations worldwide. However, no similar studies have been conducted in Egypt. Therefore, the investigators will conduct a nation-wide, collaborative, cross sectional study to determine the pattern of Parkinson's disease onset, clinical course, and non-motor symptoms among Egyptian population.
This study is designed as a prospective study, with the primary endpoint being changes in pulmonary hemodynamic parameters after ELVR in patients with severe emphysema. Secondary endpoints will be changes in lung function parameters, exercise capacity, and QoL.
Culture media used to support development of zygotes to the blastocyst stage is based on two basic philosophies: a single step medium "let-the-embryo-choose" or a sequential medium "back-to-nature". For single step media, there are two types of protocol can be used for the culture of human preimplantation embryos: 1. Interrupted single medium culture, in which the medium is renewed on the Day 3 of embryo culture 2. Uninterrupted single embryo culture, in which the same single medium is used throughout the 5-6 days of culture with no replenishment or replacement on Day 3. Investigators aim to compare the blastocyst development and clinical outcome between the two types of protocols of a single medium (with or without renewal on Day 3)
Development of pulmonary hypertension (PH) in chronic lung diseases has both functional and prognostic implications . PH in Lung diseases is usually mild to moderate with preserved cardiac output, and evolves slowly alongside the progression of lung disease and hypoxemia . However, a minority of patients develop severe PH with elevations in pulmonary artery pressure that have been described as ''out of proportion'' to the underlying disease . The aim of this study is to compare the characteristics and outcomes of consecutive patients with PH-due to lung diseases diagnosed at our specialist referral center over a 1-year period.
The study will recruit 150 patients with HCV related HCC ,after HCC treatment the patients will undergo treatment with different regimens of DAAs.
In this study, the investigators will study spinal anesthesia for laparoscopic cholecystectomy in comparison to general anesthesia (GA) regarding patient satisfaction as a primary variable, intraoperative complications, postoperative analgesic requirements, postoperative nausea and vomiting, patient hospital stay (secondary variables).
- Measuring the incidence and prevalence of PAH in Egyptian patients with different types of MCD - Determination of survival & the risk factors of mortality.
Two hundred and thirty women with expected poor ovarian response undergoing IVF/ICSI will be randomly divided into 2 equal groups using computer generated random numbers. Group 1 will receive DHEA 25 mg (DHEA 25mg, Natrol , USA) t.d.s for 12 weeks before starting IVF/ICSI cycle in addition to Growth hormone (GH; Somatotropin, Sedico, Egypt) 4 IU on day 6 of human menopausal gonadotropin (hMG) stimulation in a daily dose of 2.5 mg subcutaneous (sc) until the day of human chorionic gonadotropin (hCG) triggering Group 2 will receive an oral placebo t.d.s. daily for 12 weeks before ICSI in addition to a sc placebo similar to GH daily from day 6 of stimulation until the day of hCG trigger.
the study aims to evaluate the role of airway ultrasound as a new evolving modality in assessment and management of airway in surgical patients
Trans vaginal ultrasound with a partially full bladder will be done at gestational age earlier than 10 weeks to assess the site of intrauterine gestational sac to the endometrial cavity and the distance between the implantation site and the internal cervical os . Doppler assessment of the retrochorionic blood flow at the area behind the maximum chorionic tissue to detect resistance index.
