Filter by:This trial studies how well dynamic susceptibility contrast-magnetic resonance imaging (MRI) works in determining radiation necrosis and tumor progression in participants with cancer that has spread to the brain and are being treated with radiation therapy. Diagnostic procedures, such as dynamic susceptibility contrast-MRI, may improve the ability to determine indeterminate post-treatment changes seen on imaging after radiation therapy.
The purpose of the study is to assess the frequency and intensity of intramyocardial haemorrhage in patients with primary STEMI and different reperfusion strategies.
The study design is a multi-center, prospective, non-controlled, consecutive cohort postmarket clinical follow-up study to obtain survival and outcome data on the Allofit IT Shell in combination with Longevity Liners in primary total hip arthroplasty.
This is a multi-center, prospective, non-controlled post market surveillance study. The objectives of this study are to obtain survival and outcome data on the Allofit IT Shell in combination with the BIOLOX® delta Taper Liner when used in primary total hip arthroplasty.
The study is a multicenter, prospective, non-randomized, non-controlled consecutive cohort post-market clinical follow-up study.
proper disinfection of root canal system before obturation is a must for long term success of endodontic treatment, therefore a proper irrigant is mandatory, therefore investigators are studying the antibacterial effects of 4 different irrgating solutions in root canal treatment of patients diagnosed with necrotic pulps in their mandibular posterior teeth. patients will be recruited from outpatient clinic of the endodontic department in cairo university. endodontic treatment will be carried out as usual and samples from the infected root canals will be collected before and after preparation to be cultivated and analyzed at the laboratories of microbiology of faculty of medicine, cairo university
One of the most serious sequelae of femoral neck fractures (FNFs) is avascular necrosis (AVN) and nonunion, and this translates to a significant morbidity and mortality. This study was conducted to determine the relationship between the etiologies and management of FNFs in our institution and its relationship to the development of AVN or nonunion.
An observational study assessing the impact of anti-citrullinated antibody (ACPA) in rheumatoid arthritis (RA) participants who have received abatacept or tumour necrosis factor inhibitors (TNFi) from the Optimising Patient outcome in Australian rheumatoLogy (OPAL) registry
Trial is designed to allow revascularization and tissue engineering in necrotic teeth with peripical lesion in a single visit approach. different disinfection protocols is used to ensure that adequate disinfection of root canals is achieved to allow stem cells to differentiate and proliferate generating pulp like tissue and turning back tooth to live with periapical healing of resorbed bone.
This is a controlled, randomized, double-blind clinical study (researcher and research participant does not know which group they belong to), with the objective of evaluating clinical and radiographic performances of primary molar canal treatments with necrotic pulps using two obturator pulps. The CTZ paste (composed of chloramphenicol, tetracycline, zinc oxide and eugenol) and the ZOE paste (composed of zinc oxide and eugenol). The CTZ paste represents an alternative treatment that makes possible to treat canals of primary molars in a simplified way, without instrumentation of root canals. Studies with the CTZ pulp have demonstrated satisfactory clinical and radiographic results in addition to biocompatibility and good antimicrobial action. The zinc oxide and eugenol paste has been studied, presents good clinical and radiographic results, it is indicated by the American Academy of Paediatric Dentistry and requires mechanical chemical preparation of the root canals. Children of both sexes, frequenters of the paediatric dentistry clinic of the Federal University of Piaui who present lower deciduous molars with clinical history and / or radiographic evidences of pulp necrosis will participate in the study. The hypothesis of the study is that both pastes present similar clinical and radiographic results.
