Filter by:The aim of this prospective study is to evaluate presence and quantity of nano-sized particles and interindividual differences in their distribution and elemental composition in human nasal mucosa obtained by mucotomy in patients diagnosed with chronic hypertrophic rhinosinusitis and to compare the obtained results with control specimen obtained from stillborn children.
Pulmonary Embolism (PE) is a frequent and severe disease with an annual incidence of about 75000 cases in France and a short-term mortality rate of about 10%. Death is usually related to an acute right ventricular (RV) failure due to the increase in right ventricular afterload. Treatment of PE with RV failure consists in fluid expansion and thrombolysis in case of shock. However several studies suggest that fluid expansion may worsen acute RV failure by increasing RV dilatation and ischemia and left ventricular compression by RV dilatation. Thus, current guidelines regarding PE treatment remain unclear about the use of fluid expansion. In a preliminary study published by our group, we showed that diuretic treatment in the setting of PE with RV dilatation is safe and is associated with an increase in urine output, a decrease in heart rate and an increase in SpO2 in normotensive patients with oliguria. This may be related to the decrease of ventricular interdependence and enhancement of both LV and RV function. The main objective of the study is to evaluate the 24-hours clinical benefit of furosemide in patients referred for acute PE with RV dilatation compared to placebo. The combination of urine output and sPESI clinical parameters reflects hemodynamic status. It is relevant as it indicates the disappearance of pre-shock symptoms and is therefore associated with a lower event risk. Thus, it allows early discharge of the patients from the intensive care unit.
The purpose of this study is to determine the effectiveness of RXI-109 in reducing the recurrence of hypertrophic scar formation following elective revision of a pre-existing hypertrophic scar.
The presence of Left ventricular hypertrophy (LVH) confers high cardiovascular risk in hypertensive patients. LVH remains highly prevalent even when blood pressure (BP) is controlled. There is increasing evidence that a major non-haemodynamic contributor to LVH is oxidative stress. Allopurinol is known to markedly reduce oxidative stress. This pragmatic randomised double blind placebo controlled trial will examine whether allopurinol (300 mg bd) regresses LV mass as assessed by cardiac magnetic resonance (CMR) in 66 patients with treated hypertension but who have persisting LVH. Endothelial and vascular function will also be assessed via flow mediated dilatation (FMD) and pulse wave analysis respectively (PWA) and plasma biomarkers of oxidative stress will be measured. The treatment (allopurinol or placebo) will last 12 months.
Assessment of wall thickness in hypertrophic cardiomyopathy (HCM) is of diagnostic and prognostic importance given its known association with sudden cardiac death. However, data regarding comparison of imaging modalities for this key measurement is lacking. This study seeks to compare assessment of maximum wall thickness between clinically indicated echocardiography (with and without contrast) and clinically indicated cardiac magnetic resonance imaging.
Thickening of the heart muscle (left ventricle) known medically as Left Ventricular Hypertrophy (LVH) is very common in patients with heart disease. This increases risk of cerebrovascular/cardiovascular event. LVH is asymptomatic and managed by the use of medication to control blood pressure, however LVH may be seen in normotensive patients where factors such as obesity and insulin resistance are present. Insulin resistance is a condition where although the body produces insulin it is unable to utilize it effectively. Metformin, a drug used to treat diabetes, can reduce insulin resistance and cause weight loss, it may therefore improve LVH. This study will investigate the ability of metformin to reduce LVH in patients with heart disease, this may be a novel way forward in the risk reduction of cerebrovascular/cardiovascular events. Participants will be identified throughout NHS Tayside, those eligible will be randomly allocated to either metformin or a dummy medication (placebo) and will receive one year of treatment. At the beginning of the study, the thickness of the heart muscle will be measured by ultrasound scan and cardiac Magnetic Resonance Imaging (cMRI). We will also perform non-invasive tests to measure blood vessel function. These tests will be repeated after one year. At the end of the study, we will investigate the difference between placebo treatment and metformin treatment. This study is funded by the British Heart Foundation.
The purpose of this study is to determine the prevalence in Belgium of Fabry disease in patients with unexplained hypertrophic cardiomyopathy measured by echocardiography and to determine in Fabry patients which was the most frequently initial symptom. Actually the early diagnosis is important because a treatment exists that can prevent future complications.
The aim of this study is to compare two different techniques (portal vein embolization and radiofrequency assisted liver partition with portal vein ligation) for increasing liver volume prior to major liver resection.
Postoperative pain following tonsillectomy or adeno-tonsillectomy in children is severe and sometimes last for days. Sufentanil is used by epidural route for postoperative analgesia in children. There are few reports about its use for postoperative analgesia by continuous intravenous infusion. Its complications include , hypoxia, sedation, pruritus ,nausea and/or vomiting. The investigators design this protocol to test efficacy of analgesia of three different rates of continuous intravenous sufentanil infusion for postoperative pain management following coblation tonsillectomy or adeno-tonsillectomy in children. The investigators also compare incidence rate of complications for three groups.
