Filter by:This is a retrospective observational study to investigate the clinical, analytical and neuroimaging data generated during routine clinical management of intracerebral hemorrhage. The study will review the data from about 500 patients attended during the last ten years in the Neurology Department of Hospital Parc Taulí de Sabadell. The aim is to measure the size of the lesion in neuroimage (TC and MRI), the edema, the alterations in diffusion weighted images and to correlate this data with clinical parameters and analytical measurements. With this approach investigators plan to investigate the incidence of hematoma growth, the role of perilesional edema and diffusion changes, and the relation between neuroimaging findings and clinical outcome. The study also try to establish significant correlations between clinical and analytical data, the clinical outcome and and the magnitude of changes in neuroimaging.
it was planned to investigate the treatment effect of levonorgestrel releasing intrauterine device in patient with isthmocele who were suffering from postmenstrual spotting bleeding and who had no desire for fertility.
Bleeding remains the leading cause of death in combat, and the literature suggests that tourniquetable hemorrhage is the second leading cause of preventable death, behind non- tourniquetable hemorrhage. Currently, most Western armed forces recommend the use of the tactical tourniquet in combat for the management of tourniquetable hemorrhage. The SOFTT® tourniquet (Tactical Medical Solutions, Anderson) is the tactical tourniquet currently in use by the French armed forces. As the contract will soon come to an end, the question of its renewal arises. The purpose of this study is to compare 4 commercially available tactical tourniquets in healthy volunteers. The hypothesis of the research is that one of the 4 tourniquets compared is faster to set up than the others.
As technology advances, vitrectomy cutters are smaller and cut rates have become faster. In this prospective study, the vitrectomy efficiency and safety between 5,000 cuts per minute with 10,000 cuts per minute are compared
Intracranial pressure is usually measured by invasive methods requiring an intracranial sensor. There is no non-invasive monitoring method recognized as a gold standard. Tympanometry would make it feasible to evaluate intracranial pressure through sensitive and specific changes in the energy absorbance of the middle ear. It could represent a non-invasive method of monitoring intracranial pressure. This is a prospective monocentric longitudinal study. All adult patients in intensive care for head trauma, intracranial hypertension, or after cranial surgery and requiring invasive monitoring of ICP will be included after their non-opposition has been collected. In a group of 10 controls, multifrequency tympanometry will be performed in the standing position, in the 0° supine position and in the Tredelenburg position at -17°.
The primary objective of this trial is to provide preliminary safety data of minimally invasive endoscopic surgery using the Axonpen™ system for spontaneous intracerebral hemorrhage (ICH). The effectiveness of the Axonpen™ system in early hematoma removal and the surgical impact on subject's functional recovery will also be evaluated. The Axonpen™ system, consisting of a neuroendoscope (Axonpen) and a monitor (Axonmonitor), is cleared by FDA and indicated for the illumination and visualization of intracranial tissue and fluids and the controlled aspiration of tissue and/or fluid during surgery of the ventricular system or cerebrum.
Intravitreal injections (IVI) are the mainstay of treatment modality in many ophthalmologic diseases including neovascular age-related macular degeneration (AMD), diabetic retinopathy and retinal vascular occlusions. Patients endure monthly IVI for several years. Although standardized topical anesthesia protocols are being carried out, many still suffer from pain during and after the procedure. Previous studies at the investigators clinic have demonstrated that alpha-agonist eye drops and cool eye compresses can be successfully used in order to reduce pain levels when administered prior to IVI. In the current research, the investigators wish to study whether cooled anesthetic eye drops and antiseptics can be utilized as well to reduce the pain and subconjunctival hemorrhage caused by bevacizumab IVI.
The rationale of this study in UGIB patients is to assess whether the prediction of mortality and morbidity using AIMS65 score improves when used in combination with RDW in the emergency department setting.
Transient focal neurological episode (TFNE) is the most frequent presenting symptom of convexity subarachnoid haemorrhage (cSAH) in elderly patients with non-traumatic cSAH with suspected, possible or probable cerebral amyloid angiopathy (CAA). The aim of our study was to analyse in detail clinical and MRI characteristics in these patients. Methods: We performed a retrospective study analysing baseline, acute clinical symptom (TFNE and headache), and MRI characteristics (acute cSAH and chronic CAA features) of consecutive elderly (≥55 years) patients, recruited and registered in the stroke database, between june 2008 and october 2020 of two centres (Nîmes and Montpellier University Hospital, France), presenting with cSAH with suspected, possible, or probable CAA.
Capsule Endoscopy (CE) is a safe, patient friendly and easy procedure performed for the evaluation of gastrointestinal tract unable to be explored via conventional endoscopy. The most common indication to perform SBCE is represented by Suspected Small Bowel Bleeding (SSBB). According to the widest meta-analysis available in literature, SBCE shows a diagnostic yield in SSBB of about 60%, and angiodysplasias are the most relevant findings, accounting for 50% of patients undergoing SBCE for SSBB. Accordingly, it represents the first line examination in SSBB investigation for determining the source of bleeding, if primary endoscopy results negative. Despite its high clinical feasibility, the evaluation of CE-video-captures is one of the main drawbacks since it is time consuming and requests the reader to concentrate to not miss any lesion. In order to reduce reading time, several software have been developed with the aim to cut similar images and select relevant images. For example, automated fast reading software have demonstrated to significantly reduce reading time without impacting the miss rate in pathological conditions affecting diffusely the mucosa (as IBD lesions do). Not the same assumption can be taken for isolated lesions since several studies reported an unacceptable miss rate for such a detection modality. New advancements such as artificial intelligence made their appearance in recent years. Deep convolutional neural networks (CNNs) have demonstrated to recognize specific images among a large variety up to exceed human performance in visual tasks. A Deep Learning model has been recently validated in the field of Small Bowel CE by Ding et al. According to their data collected on 5000 patients, the CNN-based auxiliary model identify abnormalities with 99.88% sensitivity in the per patient analysis and 99.90% sensitivity in the per-lesion analysis. With this perspective, it is believable that AI applied to SBCE can significantly shorten the reading time and support physicians to detect available lesions without losing significant lesions, further improving the diagnostic yield of the procedure.
