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 investigator will test the analgesic efficacy of paravertebral morphine as an adjuvant to local anesthetics for acute postoperative pain following breast surgery and renal surgery
finding surrogate to co to trace the effect of preload challenge would make the test more applicable without the need of advanced hemodynamic monitors,suggested that co2 gap can be used to detect FR after mini fluid challenge and fluid bolts .
In this study, the investigators will assess the efficacy of growth hormone co-stimulation to GnRH antagonist regimen in poor responders to COH for IVF.
The exact mechanism of impairment of autophagy in vitiligo has not yet been determined.
Dental model cast accuracy can be affected by many variables as tray material, impression material and time elapsed before pouring the impression. All these factors would affect the accuracy of the surgical guide Impression inversion with markers technique avoids the dimension changes that may happen from pouring of the dental model cast. Also it saves time as no need for optical scan of the model cast and for scan appliance even in cases of multiple restoration. Adding markers to impression tray ensures an accurate merge even if the patient has restored dentition that may cause scatter during the CT/CBCT scan. This study will is for Assessment of the Accuracy of Surgical Guide designed from Dental Model Optical Scan versus Impression Inversion with Markers techniques in Computer Guided Implantology.
Ultrasound as a technique is safe, readily available, quick and portable allowing more accuracy of different regional blocks and local infiltration. It allows imaging of the mouth, oropharynx, infrahyoid structures, larynx, vocal cords, and trachea. Recently, ultrasound has been shown to improve accuracy in ultrasound guided block with local anesthetic infiltration. The objective of our study is to compare the effect of pre-emptive trans-oral ultrasound guided peritonsillar infiltration versus trans-cutaneous ultrasound (US) guided peritonsillar infiltration with bupivacaine for post-tonsillectomy analgesia, on surgical field, and surgeon satisfaction(intra-operative reactionary bleeding). Materials and Methods: the patients will be admitted for tonsillectomy at ENT department of the Al- Azhar university hospitals. The patients' ages between 3 to 15 years. Patients will be divided into Cutaneous group: patients will be submitted to Trans-cutaneous ultrasound guided peritonsillar infiltration with bupivacaine, and Oral group: patients will be submitted to Trans-oral ultrasound guided peritonsillar infiltration with bupivacaine.
Does the level of statistic oxidation reduction potential (sORP) affects the choice of sperm source or sperm selection method used during ICSI.
The study will evaluate the effectiveness of Tacrolimus 0.03% ointment monotherapy in patients with vitiligo. Patients will be treated for 6 months and followed for 3 months after treatment. All types of vitiligo will be included.
After major open abdominal surgery, transient paralytic ileus usually follows. It has been suggested that stimulation of pain fibers, excessive sympathetic tone, and the release of inhibitory neurotransmitters from bowel wall associated with bowel manipulation and peritoneal irritation are responsible mechanisms. There have been concerns that early postoperative oral feeding would lead to vomiting with subsequent aspiration pneumonia, anastomotic leakage, and wound dehiscence.
Comparing patient satisfaction and retention of upper complete denture fabricated using two different denture base materials, the first fabricated using rapid prototyping method while the second is following conventional methods.
