Active clinical trials for "Rupture"

The objective of this study is to assess the benefits of endovascular technique in terms of efficacy and safety of Valiant Thoracic Stent Graft with the Captivia Delivery System in the treatment of thoracic aortic disease, in a cohort of patients representative of the population treated under real-life conditions of use in France for up to 5 years.

Incident rates of ACL rupture are greatest in 16-39 year olds at almost 1 in 1,000. Performance Based Investigations (PBIs) can be used to evaluate and select correct approaches to patient treatment, and biochemical, biomechanical and physiological biomarkers in other conditions are sensitive in distinguishing between disease state severities, type of injuries and responsiveness to treatment. Despite the measurement sensitivity of PBIs, these are not widely used possibly owing to their focus postoperatively where benefits are less worthwhile. This study aims to investigate novel biomarkers as performance based investigations (PBIs) to improve surgical and treatment strategies in anterior cruciate ligament (ACL) patients. The objectives are to identify whether biomarkers, collected before and after operations, can: 1) Assist the surgeon in decision making; 2) Lead to improved prognosis; 3) Be used to predict the outcomes of prognosis, and; 4) Correlate with disease signs/ smoking to help further understand ACL injuries.

Preterm Premature Rupture of Membranes (PPROM) is treated with an antibiotic, erythromycin or azithromycin, to prolong pregnancy. Erythromycin is taken for several days and can result in stomach upset in some patients, causing them to stop taking the medication. Therefore, azithromycin is often prescribed instead. Azithromycin is usually taken only once and stomach upset is not seen or greatly reduced. The goal of this study is to see if there is a difference between the antibiotic (azithromycin) compared to the antibiotic (erythromycin) in prolonging pregnancy in patients with Preterm Premature Rupture of Membranes (PPROM). The working hypothesis is that there is no difference in the clinical effectiveness between antibiotic regimens containing te macrolides azithromycin and erythromycin for prolonging latency in PPROM.

About 20 years ago synthetic ligaments were used in orthopaedics / traumatology for the repairing and replacement of injuries of the anterior cruciate ligament. After less than 10 years it appeared that a relatively important number of patients showed complications on the basis of synovitis. The situation of another group of patients on the other hand evolved favourably without complications. The study to focuses on this group of patients and attempts to determine how the replacement without problems ab initio, evolved in the time. It concerns a group of 57 patients who received an implantation in the UZ Ghent between November 85 and October 87 with the Stryker Dacron ligament and a group of 33 patients who received the Trevira ligament in the ASZ Aalst. The clinical result will be stipulated by means of standardized questionnaires and a clinical examination. The radiological result will be determined by the degree of integrity of the ligament that was implanted at the time. In this way the study could give an idea about the degree in which the technical success of the intervention correlates with the clinical success 20 years later.

Thirty patients scheduled to coronary angiography and IVUS in according to their treating physician decision will be enrolled in the study. The coronary angiography and IVUS will be done on according to regular clinical standards. As the study protocol, 40 cc of blood will be drawn from the patients after written informed consent. The laboratory tests will be processed for the above mentioned serum markers of unstable plaque. A multivariate correlation test will be done between the different serum markers and the plaque morphology by angiography and composition (virtual histology) by IVUS.

Our main hypothesis is to consider that the detection of biomarkers on admission combined with the length of the cervix would improve the prediction of the latency period in case of preterm premature rupture of membranes (pPROM). The primary purpose of the protocol is to assess the performance of these tests to predict a latency period <48 hours in case of pPROM.

Searching a dysfunction of corticotropic and thyrotropin axis during the acute phase ( ≤48h ) of a subarachnoid hemorrhage secondary to spontaneous rupture of cerebral aneurysm. Impact on the incidence of complications and recovery are evaluated at 1 month. Blood sample are made within 48 hours of the onset of bleeding with assay of total plasma cortisol, plasma ACTH at 8 am and thyroid hormones (T3, free T4 , and TSH). Dynamic test ACTH stimulation (test Synacthene) with renewal of serum cortisol to H + 1 (60min). Evaluation in the first 30 days of the incidence of rebleeding, hydrocephalus, of vasospasm, infection and epilepsy. GOS to 1 month.

A normative development concerning the mechanical resistance tests of the the femoral stems led to contraindicate, in September 2014, to implant Meije Duo ™ femoral stems size 1 or 2 in patients weighing more than 60 kg due to an assumed risk of femoral stem breakage. This contraindication is based on standardized mechanical tests which may have not taken into account the changes in patient weight that may occur after the intervention. To date, investigators have not been aware of any Meije Duo ™ size 1/2 brakeage in our patients implanted with this type of prosthesis regardless of their weights before 2014. However, it is possible that some of them have had a prostheses failure and consulted another hospital. In the absence of a clinical study on this problem, investigators decided to set up a health care assessment study collecting retrospective and prospective information from our patients.

First aim: PARIS study The main aim of the current study is to determine the association between abdominal aortic aneurysm (AAA) progression and the evolution of proteases and cytokines levels.To achieve this aim, we will prospectively collect blood, aortic tissue, patient data, and imaging data. Aortic tissue will only be obtained when patients undergo conventional open repair. The other biomaterials will be collected during regular patient follow-up visits, with a maximum frequency of once per year. Second aim: Pearl AAA biobank For future research purposes, a new biobanking infrastructure will be created to collect and store additional blood and urine samples in a biobank. This biobank will be embedded within the infrastructure of the 'Parelsnoer Institute' (PSI) and will be called Pearl AAA. The Pearl AAA will be established in the extension of the PARIS study

The objective of this prospective cohort study is to determine the prevalence of obstructive sleep apnoea (OSA) in patients with and without thoracic aortic aneurysm.
