Filter by:In Patients with minor head injury measurement of protein S100 will be introduced to the emergency departement as another tool to rule out intracerebral bleeding.
This is a pilot study to test feasibility of collection, preparation and infusion of a baby's own (autologous) umbilical cord blood in the first 14 days after birth if the baby is born premature <35 weeks of gestation.
Postpartum haemorrhage (PPH) remains the major cause of maternal mortality in France. The most efficient treatment of severe PPH is sulprostone which is associated with cardiac complications. The objective of this study was to assess the efficacy and the safety of intrarectal misoprostol for curative postpartum haemorrhage treatment. We conducted a multicenter double blind randomized placebo control trial between June 2004 and December 2007, among consenting women with postpartum haemorrhage and failure to oxytocin treatment. Our main criteria of judgement was quantification of blood loss and the use of sulprostone between the two groups using either misoprostol intrarectal tablets (5X200mg ) or placebo in similar opaque introducer.
This study examines early antiepileptic treatment with valproic acid for acute cerebral hemorrhage against a placebo group immediately post event to evaluate the outcome of these patients regarding seizures and neurological outcome.
Up to 5% of patients with recurrent gastrointestinal (GI) bleeding remain undiagnosed by upper endoscopy and colonoscopy, the presumed source of bleeding in these patients being the small intestine. These patients fall under the category of "obscure gastrointestinal bleeding," and frequently require an extensive diagnostic work-up. Obscure gastrointestinal bleeding (OGIB) refers to bleeding undiagnosed by upper endoscopy and colonoscopy. In 40-70% of cases of OGIB, a bleeding lesion is localizable to the small bowel. In OGIB, capsule endoscopy (CE) has a diagnostic yield of 40-80%, and has demonstrated diagnostic superiority to push enteroscopy, barium studies, angiography, CT angiography, and routine abdominal CT scan. When CE is non-diagnostic, however, the subsequent diagnostic algorithm is not well-defined. There is currently no established role for cross-sectional imaging for this indication. CT enterography (CTE) combines the spatial and temporal resolution of CT with an orally administered neutral enteric contrast material that permits detailed visualization of the small bowel. Unlike other imaging modalities such as nuclear medicine techniques and catheter angiography, CT is less labor-intensive, more readily available, and provides precise anatomic localization. A novel OGIB-protocol available at Brigham and Women's Hospital for CTE utilizes a dual-phase, dual energy technique that obtains images at two time points to better identify active bleeding in the mesentery. We, the investigators, plan to prospectively study an algorithm that employs CTE and compare to capsule endoscopy to investigate the effectiveness of both modalities and to evaluate the potential role of CTE in OGIB. The goal of our study is to determine observationally the contribution of both CE and the new protocol for CTE to the evaluation and management of overt obscure GI bleeding and accordingly revise the clinical algorithm. We hypothesize that CTE will be as or more effective than CE at identifying culprit lesions in overt, obscure gastrointestinal bleeding.
The purpose of this study is to examine the impact of cranioplasty on cerebral hemodynamic and blood flow as prognostic factor in patients receiving decompressive craniectomy for Head injuries, Subarachnoid haemorrhage, intra-cerebral haemorrhage, cerebral dural sinus thrombosis, malignant middle cerebral artery stroke.
To demonstrate that the combined used of oxytocin and misoprostol prevent from post partum haemorrhage better than oxytocin alone, following vaginal birth at 36 to 42 weeks.
Previous studies showed that combination of endoscopic therapy with vasoconstrictor is better than either vasoconstrictor or endoscopic therapy alone in achieving the successful hemostatsis of acute variceal bleeding. The rationale of using vasoconstrictor is to enhance the efficacy of hemostasis by endoscopic therapy. Nowadays, endoscopic variceal ligation (EVL) has replaced endoscopic injection sclerotherapy (EIS) as the endoscopic treatment of choice in the arresting of acute esophageal variceal hemorrhage. EVL alone can achieve hemotasis up to 97% even in cases of active variceal hemorrhage. However, early rebleeding due to ligation-induced ulcer may be encountered. It appears that prevention of esophageal ulcers and bleeding by a proton pump inhibitor may be more logical than using a vasoconstrictor after cessation of bleeding by EVL.
In remote preconditioning, ischemia in one organ protects distant organs from ischemic insults. e.g. brief induced limb ischemia protects the brain from an otherwise more severe stroke. The objective of this study is to determine if remote ischemic preconditioning can be safely and effectively instituted in patients with subarachnoid hemorrhage, who are at high risk for developing disabling cerebral ischemia. The investigators will also preliminarily assess if there is evidence for neuroprotection. This will be a Phase 1b study. Additional objectives are: 1. to determine if remote ischemic preconditioning can be safely and effectively instituted in patients with subarachnoid hemorrhage, who are at high risk for developing disabling cerebral ischemia. 2. analogously to a dose-escalation study the investigators propose to study the safety and tolerability of increasing durations of limb ischemia until a target time of 10 minutes of limb ischemia has been reached.
Intrathoracic positive pressure may lead to a change hemodynamics, with repercussions for the intracranial compartment, thereby altering intracranial pressure (ICP) and cerebral perfusion pressure (CPP). This effect may become more intense when using high positive end expiratory pressure (PEEP) values. The aim of the present study was to measure the impact of different PEEP values on ICP, CPP and mean arterial pressure (MAP). MAP, whereas high PEEP values increase ICP, although without clinical relevance.
