Filter by:Transcranial Doppler ultrasonography is usually used in the evaluation and management of patients with brain injury. This noninvasive method measures local blood flow velocity and direction in the proximal portions of large intracranial arteries. The operator requires a short training and experience to perform. The third ventricle diameter measurement by transcranial duplex flow sonography was performed in healthy volunteers . This studies show similar results in those obtained with the MRI or Computer Tomography (CT). Currently the third ventricle diameter measurements by transcranial Doppler ultrasonography was not validated for neuro-intensive care unit patients. The investigators propose to used recent ultrasound system to validate the third ventricle diameter measurements in comparison with the standard method (CT).
Verticalization was reported to improve the level of arousal and awareness in patients with severe acquired brain injury (ABI) and to be safe in ICU. The investigators evaluated the effectiveness of a very early stepping verticalization protocol on the functional and neurological outcome of patients affected by disorder of consciousness due to ABI. Consecutive patients with Vegetative State or Minimally Conscious State were enrolled in ICU on the third day after an ABI. They were randomized to undergo conventional physiotherapy alone or associated to fifteen 30-minute sessions of verticalization, using a tilt table with robotic stepping device. Once stabilized, patients were transferred to a Neurorehabilitation unit for an individualized treatment. Outcome measures were assessed on the third day from the injury (T0), at ICU discharge (T1) and at Rehab discharge (T2).
Mild traumatic brain injury (mTBI) is a very common reason for presentation to pediatric emergency departments. So as not to overlook the risk of complications, which occur at a rate of 0-7%, measures such as cranial computed tomography (CCT-scan) and/or short inpatient observation are prescribed. Ultimately, the majority of these measures could be avoided and a large Australian cohort shows that the risk of brain tumors is 2.44 times higher for children who had a CCT-scan (3.24 for age 1-4 years). Assay of a sensitive biomarker in blood, such as the S100B protein, has the potential to reduce the number of these unnecessary measures.
Extremely low birth weight (ELBW), birth weight less than or equal to 1000 g, infants are at high risk for developing brain injury in the first week of life. Intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL) are the most common injuries in this group of infants. Their incidence is inversely proportional to gestational age (GA) and birth weight (BW). These lesions are associated with neurodevelopmental delay, poor cognitive performance, visual and hearing impairment, epilepsy, and cerebral palsy; and instability of systemic hemodynamics during transition from intra- to extra-uterine life and during the early neonatal period is believed to be at their genesis. While the incidence of ultrasound- diagnosed cystic PVL has decreased dramatically over the last 2 decades, diffuse PVL detected by magnetic resonance imaging (MRI) is still prevalent in survivors of neonatal intensive care. Moreover, PVL, even when non-cystic, is associated with decreased cortical complexity and brain volume and eventual neurocognitive impairment. Currently, clinicians lack the tools to detect changes in cerebral perfusion prior to irreversible injury. Unfortunately, the incidence of brain injury in ELBW infants has remained relatively stable. Once translated to the bedside, the goal of this research is to develop a monitoring system that will allow researchers to identify infants most at risk for IVH and PVL and in the future, intervention studies will be initiated to use the changes in cerebral perfusion to direct hemodynamic management. The purpose of this study is to first understand the physiology of brain injury and then to eventually impact the outcomes in this high-risk group of infants by assessing the ability of the diastolic closing margin (DCM), a non-invasive estimate of brain perfusion pressure, to predict hemorrhagic and ischemic brain injury in ELBW infants. The information collected for this study will help develop algorithms or monitoring plans that will maintain the appropriate brain perfusion pressure and thereby, prevent severe brain injury.
The multi-center study evaluates BrainPulse recordings from subjects with a suspected or confirmed concussion to improve a concussion detection algorithm. Subjects may also consent for a 5 additional follow-ups over a 21-day period to compare the progression of change in their BrainPulse recordings.
The goal of this project will be to demonstrate that Synaptive Medical's Diffusion Tensor Imaging(DTI) product functionality used in pre-operative planning and intraoperative surgical navigation, improves clinical outcomes corresponding to a reduction in neurological and neuropsychological deficits in pediatric brain tumor surgery.
We will determine the incidence and magnitude of cerebral desaturation in TBI. Adult patients (18 years and older) admitted to the Surgical/Trauma Intensive Care Unit (ICU) at the Health Sciences Center with a severe TBI will have cerebral oximetry monitoring instituted within 12 hours of admission and continuing for 72 hours after placement. Decreases in regional cerebral oxygenation will be correlated with ICU hemodynamic parameters including mean arterial pressure, intracranial pressure, and arterial oxygen and carbon dioxide tension.
The GASPAR trial is a pragmatic, parallel-arms, single-center, non-blinded, superiority randomized control trial in neurorehabilitation. The main objective is to test whether a 4 weeks gait rehabilitation program that uses augmented reality is superior to a conventional treadmill training program of equivalent intensity. Baseline assessments precede allocation, which consists in blocking randomization (2:1 ratio) with stratification according to the disease etiology. Post-intervention assessments serve to compare the short-term efficacy of the intervention between the two groups. Three months after discharge, follow-up assessments take place to detect potential long-term effects.
The investigators aim to retrospectively map the delays in the acute care of traumatic brain injury patients necessitating emergent craniotomies.
This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/
