Acute Blood Pressure Management in Neurocritically Ill Patients.

Pharmacotherapy 2019 Feb 7. Epub 2019 Feb 7.

University Hospitals Cleveland Medical Center, Cleveland, OH.

Optimal blood pressure management is controversial in neurocritically ill patients due to conflicting concerns of worsening ischemia with decreased blood pressure versus cerebral edema and increased intracranial pressure with elevated blood pressure. In addition, there is a lack of high-quality evidence regarding optimal blood pressure goals in patients with most of these conditions. This review summarizes guideline recommendations and examines the literature for blood pressure management in patients with ischemic stroke, intracerebral hemorrhage, aneurysmal subarachnoid hemorrhage, traumatic brain injury, and spinal cord injury.

MR Imaging for Assessing Injury Severity and Prognosis in Acute Traumatic Spinal Cord Injury.

Radiol Clin North Am 2019 Mar 17;57(2):319-339. Epub 2018 Nov 17.

Department of Neurological Surgery, University of California, San Francisco, 505 Parnassus Avenue, Room M779, San Francisco, CA 94143, USA; Brain and Spinal Injury Center, Zuckerberg San Francisco General Hospital, 1001 Potrero Avenue, San Francisco, CA 94110, USA.

T2-weighted (T2W) imaging is the most important sequence for detection of acute traumatic spinal cord pathology in clinical practice. Intramedullary hemorrhage on T2W imaging is associated with some component of irreversible injury and arguably the most robust MR imaging predictor of injury severity. The MR imaging appearance of the injured spinal cord in the early stages of injury is highly dynamic, and the time delay from injury to imaging must be considered in image interpretation. Read More

Microvascular endothelial cells engulf myelin debris and promote macrophage recruitment and fibrosis after neural injury.

Nat Neurosci 2019 Jan 21. Epub 2019 Jan 21.

Department of Biomedical Sciences, Florida State University College of Medicine, Tallahassee, FL, USA.

The clearance of damaged myelin sheaths is critical to ensure functional recovery from neural injury. Here we show a previously unidentified role for microvessels and their lining endothelial cells in engulfing myelin debris in spinal cord injury (SCI) and experimental autoimmune encephalomyelitis (EAE). We demonstrate that IgG opsonization of myelin debris is required for its effective engulfment by endothelial cells and that the autophagy-lysosome pathway is crucial for degradation of engulfed myelin debris.

Acute heat stress reduces biomarkers of endothelial activation but not macro- or microvascular dysfunction in cervical spinal cord injury.

Am J Physiol Heart Circ Physiol 2018 12 21. Epub 2018 Dec 21.

School of Health and Exercise Sciences, University of British Columbia - Okanagan.

Cardiovascular diseases (CVD) are highly prevalent in spinal cord injury (SCI) and peripheral vascular dysfunction might be a contributing factor. Recent evidence demonstrates that exposure to heat stress can improve vascular function and reduce the risk of CVD in uninjured populations. We therefore aimed to examine the extent of vascular dysfunction in spinal cord injury (SCI) and the acute effects of passive heating. Read More

Surgical Dissection of a Perimedullary Fistula of Conus Medullaris With Long-Term Follow-Up: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2018 Dec 19. Epub 2018 Dec 19.

Department of Neurologic Surgery, Mayo Clinic, Rochester, Minnesota.

Perimedullary fistulae of the spinal cord are rare vascular lesions that can present with different clinical patterns: hemorrhage, progressive myelopathy due to arterial steal and/or venous congestion, or symptoms due to compression of neural structures by engorged vessels. Treatment consists of surgical excision, endovascular embolization, or a combination of the two. If complete obliteration of the nidus exposes the patient to undue risk of permanent neurological deficits, incomplete obliteration with reduction of the vascular supply is a reasonable compromise to improve clinical symptomatology.

Semin Ultrasound CT MR 2018 Dec 19;39(6):551-569. Epub 2018 Oct 19.

Department of radiology, University of Miami Miller School of Medicine, Miami, FL.

Spinal emergencies and urgent conditions must be recognized early so that the diagnosis can be quickly confirmed and treatment can be instituted to possibly prevent permanent loss of function. The American College of Radiology provides guidelines for recognition of patients presenting with myelopathy or acute low back pain who require further evaluation for suspicion of more serious problems and contribute to appropriate imaging utilization. Spinal emergencies include spinal cord compression secondary to vertebral fracture or space occupying lesion, spinal infection or abscess, vascular or hematologic damage, severe disc herniation, and spinal stenosis.

Department of Radiology, National Cerebral and Cardiovascular Center, 5-7-1, Fujishiro-dai, Suita, Osaka, 565-8565, Japan.

Purpose: The reliability of assessment of the artery of Adamkiewicz before the aortic repair is highly dependent on the display of the continuity of this artery with the aorta, mainly around the vertebral pedicle, by computed tomography angiography (CTA). We hypothesized that the sharp filter kernel can improve visualization of this continuity of the vessel structure because of its edge enhancement and high-spatial resolution. This study was performed to compare the subjective and objective image quality of spinal CTA reconstructed with sharp and smooth filter kernels. Read More

Erythrophages do not develop when lumbar CSF and blood samples are mixed in vitro.

Fluids Barriers CNS 2018 Nov 5;15(1):31. Epub 2018 Nov 5.

MVZ Neurologie, Constance, Constance, Germany.

Background: Cerebrospinal fluid (CSF) analysis is a crucial method in the diagnostic process for suspected subarachnoid hemorrhage (SAH), especially when cerebral imaging is negative or inconclusive. CSF cytology (detection of erythrophages or siderophages) is used to determine whether a bloodstained CSF resembles a genuine SAH. Whether erythrophages may develop in vitro after a traumatic puncture in case of delayed CSF analysis is unclear. Read More

Zhen Ci Yan Jiu 2018 Oct;43(10):674-7

Graduate School of Heilongjiang University of Traditional Chinese Medicine, Harbin 150040.

Brain plasticity is referred to the ability of the brain to change in structure and functional activities from microscopic aspects (synapses) in individual neurons to larger-scale aspects such as cortical remapping, neuronal remodeling, etc. in response to injury. Acupuncture has a positive effect in the treatment of cerebral diseases, thus leading to an increasing research on its underlying mechanisms in regulating brain plasticity. Read More

A mini-open transspinous approach for resection of intramedullary spinal cavernous malformations.

J Clin Neurosci 2018 Dec 13;58:210-212. Epub 2018 Oct 13.

University of California San Francisco, Department of Neurological Surgery, San Francisco, CA, USA. Electronic address:

Background And Importance: Advances in minimally invasive (MIS) and mini-open surgical approaches have led to reductions in perioperative morbidity without compromising rates of resection of non-degenerative intradural spinal pathologies. Whether these approaches may be adapted for the surgical resection for intramedullary vascular malformations - such as cavernous malformations (CMs) - has yet to be reported. The authors describe a mini-open transspinous approach to resect a ruptured intramedullary CM of the conus medullaris. Read More

RUNX1-EVI1 induces dysplastic hematopoiesis and acute leukemia of the megakaryocytic lineage in mice.

Leuk Res 2018 Nov 26;74:14-20. Epub 2018 Sep 26.

Department of Hematology and Oncology, Dokkyo Medical University School of Medicine, Tochigi, Japan. Electronic address:

The RUNX1-EVI1 gene generated by the t(3;21) translocation encodes a chimeric transcription factor and is a causative gene in the development of de novo acute megakaryoblastic leukemia and leukemic transformation of hematopoietic stem cell tumors. Heterozygous RUNX1-EVI1 knock-in mice die in utero due to hemorrhage in the central nervous system and spinal cord and complete abolishment of definitive hematopoiesis in the fetal liver. On the other hand, the chimeric knock-in mouse develops acute megakaryoblastic leukemia. Read More

Engaging pain fibers after a spinal cord injury fosters hemorrhage and expands the area of secondary injury.

Exp Neurol 2019 Jan 27;311:115-124. Epub 2018 Sep 27.

Cellular and Behavioral Neuroscience, Department of Psychology, Texas A&M University, College Station, TX 77843, USA. Electronic address:

In humans, spinal cord injury (SCI) is often accompanied by additional tissue damage (polytrauma) that can engage pain (nociceptive) fibers. Prior work has shown that this nociceptive input can expand the area of tissue damage (secondary injury), undermine behavioral recovery, and enhance the development of chronic pain. Here, it is shown that nociceptive input given a day after a lower thoracic contusion injury in rats enhances the infiltration of red blood cells at the site of injury, producing an area of hemorrhage that expands secondary injury.
