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.
Long bone fractures are among the most traumatic patients seen in emergency departments. Using ultrasound to diagnose long bone fractures can reduce the risk of complications occurring During the primary and secondary survey. The diagnosis of long bone fractures is traditionally accomplished through plain radiographs taken at perpendicular angles to each other. Because of the resources required for radiographic capability, X-ray can be inaccessible in rural or remote areas, or in hospital during break time, In settings where a radiography technologist is not present on-site or in patient have conditions do for him limitations movement Using ultrasound machines to do patient examination can be performed earlier of assessment, and at the bedside, reducing diagnostic delays and time to initiation of management. Additional Advantages of Ultrasound include its simplicity, portability, repeatability, and its lack of ionizing radiation. Using ultrasound technology don't need equipment for lead protectors on health care providers, as well as the harmful effects to patients of ionizing radiation and safe to use with pregnant patients in the first and second trimester. However, this technique can be impractical because the training necessary for the use of this technology Diagnosis of long bone fractures in primary assessment can decrease risk of complications such as shock, bleeding, swelling, embolism compartment syndrome, vascular or neurological damage and patient's transposition related change shape and type of a fracture. that complications can lead to life-threatening conditions up to death specifically in geriatric and paediatric Patients
The aim of this study is to evaluate effects of clear aligners versus fixed appliances on occlusion after treatment of mild anterior crowding a T-scan study.
The present study will be directed to evaluate the effect of low-level laser therapy on root resorption during orthodontic intrusion of upper incisors.
Patients with orofacial pain lasting at least 3 months. The patients will be randomly assigned to one of the two groups according to the treatment method: group I (intraoral injection) and group II (transcutaneous injection) where each patient injected Botox at each trigger point according to the treatment group by the same operator. Patients will be examined by a blinded investigator at pre- and post-injections at the following intervals: during diagnosis, 1 week, 4, and 6 weeks post-injection. The patients will be assessed using a pain score measured on a 10-point visual analog scale (VAS). The secondary outcome assessed will be measuring the quality of life in an Oral Health Impact Profile questionnaire (OHIP-14).
Stroke is a highest reason of illness and death all over world. In 2017, stroke was the second greatest recurrent reason of mortality, after ischemic cardiac illness, and produced 6.2 million mortality all over world. The load of stroke does not only lie in the great mortality but the great morbidity also results in up to 50% of survivors being chronically disabled. Thus stroke is a disease of huge public health importance with economic and social consequences.
The present prospective clinical study will be undertaken for assessment of the effect of application of i-PRF on the rate of levelling and alignment, molar distalization& intrusion of anterior teeth in deep bite cases
Research question: Dose the use of oral zinc supplement improve the effects of botulinum toxins injection in patients with myofascial pain dysfunction syndrome? Statement of the problem: MPDS Patients treated with botulinum toxin A injection usually suffers from return of the symptoms which requires successive injections almost every (3-4M) Rationale for conducting the research: The concept of adding the zinc supplementation prior to BTXA injection is contributed to the fact that botulinum toxin is a zinc-dependent metalloprotease; therefore, every botulinum toxin molecule must be accompanied with a zinc molecule to effectively paralyze a muscle. However, commercially available BTXA preparations exclude zinc from their preparations, and BTX clinical efficiency and duration varies according to the zinc levels of the patient. Although the BTX effect could remain for several months, its zinc-dependent proteolytic activity befalls within hours of administration before the toxins are degraded in the tissues. Therefore, for achieving better results from BTX, the recipients should have adequate zinc levels at the time of administration. Therefore, oral zinc supplement intake prior to BTXA injection may enhance its clinical efficiency and duration. botulinum neurotoxins are the most potent toxins known. They bind to nerve cells, penetrate the cytosol and block neurotransmitter release. Comparison of their predicted amino acid sequences reveals a highly conserved segment that contains the HExxH zinc binding motif of metalloendo peptidases. The metal content of tetanus toxin was then measured and it was found that one atom of zinc is bound to the light chain of tetanus toxin. Zinc could be reversibly removed by incubation with heavy metal chelators. Zn2+ is coordinated by two histidines with no involvement in cysteines, suggesting that it plays a catalytic rather than a structural role. Bound Zn + was found to be essential for the tetanus toxin inhibition of neurotransmitter release in Aplysia neurons injected with the light chain. The intracellular activity of the toxin was blocked by phosphoramidon, a very specific inhibitor of zinc endopeptidases. Purified preparations of light chain showed a highly specific proteolytic activity against synaptobrevin, an integral membrane protein of small synaptic vesicles. The present findings indicate that tetanus toxin, and possibly also the botulinum neurotoxins, are metalloproteases and that they block neurotransmitter release via this protease activity. So The use of zinc supplementation prior to BTXA injection has been suggested by several previous studies to prolong its duration of action as well as improve its efficacy
The aim of this study is to compare the treatment results when treating Class II division 1 malocclusion using the Van Beek-Headgear Activator combination (vBHGA) appliance versus using the Andresen activator.
Assessment of maxillary canine retraction using self-ligating brackets system assisted with micro-osteoperforations: A prospective controlled clinical study
Aim of the work This study aims to evaluate the possible beneficial role of silymarin in attenuating both doxorubicin related cardiac and hepatic toxicities and paclitaxel associated peripheral neuropathy and improving cognitive impairment in patients with breast cancer. This study will be a randomized placebo controlled parallel study. The study will be performed in accordance with the ethical standards of Helsinki declaration in 1964 and its later amendments. Group one: (Placebo group; n=28) which will receive four cycles of AC regimen (doxorubicin and cyclophosphamide; each cycle was given every 21 day) followed by 12 cycles of paclitaxel (each cycle was given in a weekly basis) plus placebo tablets once daily. Group two: (Silymarin group; n=28) which will receive the same regimen plus silymarin 140mg once daily
