Dynamic features of brain edema in rat models of traumatic brain injury.

Neuroreport 2019 Apr 8. Epub 2019 Apr 8.

Department of Radiology, Chongqing Seventh People's Hospital, Chongqing, China.

We explored the dynamic features of brain edema after traumatic brain injury (TBI) using healthy adult male Wistar rats. After inducing moderate brain injuries in the rats, we divided them randomly among seven groups on the basis of the time elapsed between TBI and examination: 1, 6, 12, 24, 48, 72, and 168 h. All rats were scanned using diffusion-weighted imaging (DWI) to observe tissue changes in the contusion penumbra (CP) after TBI. Read More

Astrocyte-selective AAV gene therapy through the endogenous GFAP promoter results in robust transduction in the rat spinal cord following injury.

Gene Ther 2019 Apr 8. Epub 2019 Apr 8.

Centre for Brain Research, University of Auckland, Auckland, New Zealand.

Adeno-associated viral (AAV) vectors are a promising system for transgene delivery into the central nervous system (CNS) based on their safety profile and long-term gene expression. Gene delivery to the CNS has largely been neuron centric but advances in AAV technology are facilitating the development of approaches to enable transduction of glial cells. Considering the role of astrocytes in the on-going secondary damage in spinal cord injury (SCI), an AAV vector that targets astrocytes could show benefit as a potential treatment. Read More

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

The Diffuse and Severe Traumatic Subarachnoid Hemorrhage Being Hard to Distinguish to Aneurysmal Subarachnoid Hemorrhage.

J Craniofac Surg 2019 Jan;30(1):196-199

Department of Neurosurgery, Tobu Hospital, Yokohama, Japan.

Background: In primary intracerebral hemorrhage, several studies showed that contrast extravasation (CEV) is reported to be an indicator of delayed hematoma expansion, emergent hematoma removal and poor prognosis. On the contrary in head trauma, few researches validated the effectiveness of CEV because of other influences such as subarachnoid hemorrhage (SAH), contusion or brain swelling. The authors experienced a patient showing diffuse SAH caused by traumatic mechanism with acute subdural hematoma (ASDH). Read More

Changes in Posttraumatic Brain Edema in Craniectomy-Selective Brain Hypothermia Model Are Associated With Modulation of Aquaporin-4 Level.

Front Neurol 2018 2;9:799. Epub 2018 Oct 2.

Department of Neurosurgery, Faculty of Medicine, Saarland University Medical Center, Saarland University, Homburg, Germany.

Both hypothermia and decompressive craniectomy have been considered as a treatment for traumatic brain injury. In previous experiments we established a murine model of decompressive craniectomy and we presented attenuated edema formation due to focal brain cooling. Since edema development is regulated via function of water channel proteins, our hypothesis was that the effects of decompressive craniectomy and of hypothermia are associated with a change in aquaporin-4 (AQP4) concentration.

Increases in Microvascular Perfusion and Tissue Oxygenation via Vasodilatation After Anodal Transcranial Direct Current Stimulation in the Healthy and Traumatized Mouse Brain.

Adv Exp Med Biol 2018 ;1072:27-31

Department of Neurosurgery, University of New Mexico School of Medicine, Albuquerque, NM, USA.

Traumatic brain injury (TBI), causing neurological deficit in 70% of survivors, still lacks a clinically proven effective therapy. Transcranial direct current stimulation (tDCS) has emerged as a promising electroceutical therapeutic intervention possibly suitable for TBI; however, due to limited animal studies the mechanisms and optimal parameters are unknown. Using a mouse model of TBI we evaluated the acute effects of the anodal tDCS on cerebral blood flow (CBF) and tissue oxygenation, and assessed its efficacy in long-term neurologic recovery.

Sulfonylurea Receptor 1, Transient Receptor Potential Cation Channel Subfamily M Member 4, and KIR6.2:Role in Hemorrhagic Progression of Contusion.

J Neurotrauma 2019 Apr 4;36(7):1060-1079. Epub 2018 Oct 4.

1 Department of Neurosurgery, University of Maryland School of Medicine, Baltimore, Maryland.

In severe traumatic brain injury (TBI), contusions often are worsened by contusion expansion or hemorrhagic progression of contusion (HPC), which may double the original contusion volume and worsen outcome. In humans and rodents with contusion-TBI, sulfonylurea receptor 1 (SUR1) is upregulated in microvessels and astrocytes, and in rodent models, blockade of SUR1 with glibenclamide reduces HPC. SUR1 does not function by itself, but must co-assemble with either KIR6. Read More

Stretchable Transparent Electrode Arrays for Simultaneous Electrical and Optical Interrogation of Neural Circuits in Vivo.

Nano Lett 2018 05 9;18(5):2903-2911. Epub 2018 Apr 9.

School of Life Sciences , Tsinghua University , Beijing 100084 , China.

Recent developments of transparent electrode arrays provide a unique capability for simultaneous optical and electrical interrogation of neural circuits in the brain. However, none of these electrode arrays possess the stretchability highly desired for interfacing with mechanically active neural systems, such as the brain under injury, the spinal cord, and the peripheral nervous system (PNS). Here, we report a stretchable transparent electrode array from carbon nanotube (CNT) web-like thin films that retains excellent electrochemical performance and broad-band optical transparency under stretching and is highly durable under cyclic stretching deformation.

Fatal Road Traffic Vehicle Collisions With Pedestrian Victims: Forensic Postmortem Computed Tomography and Autopsy Correlation.

Am J Forensic Med Pathol 2018 Jun;39(2):130-140

From the Department of Forensic Medicine and Imaging, Institute of Forensic Medicine, University of Zurich, Zurich, Switzerland.

Fatal car-to-pedestrian collisions regularly appear in the forensic pathologist's routine, particularly in places of extended urbanization. Postmortem computed tomography has gained an exceptional role to supplement autopsy worldwide, giving information that is supplementary or complimentary to conventional autopsy. In this retrospective study, a total number of 320 findings in a series of 21 pedestrians fatally hit by cars and trucks of both postmortem computed tomography and autopsy were correlated. Read More

Human brain trauma severity is associated with lectin complement pathway activation.

J Cereb Blood Flow Metab 2018 02 9:271678X18758881. Epub 2018 Feb 9.

1 IRCCS-Istituto di Ricerche Farmacologiche Mario Negri, Milano, Italy.

We explored the involvement of the lectin pathway of complement in post-traumatic brain injury (TBI) pathophysiology in humans. Brain samples were obtained from 28 patients who had undergone therapeutic contusion removal, within 12 h (early) or from >12 h until five days (late) from injury, and from five non-TBI patients. Imaging analysis indicated that lectin pathway initiator molecules (MBL, ficolin-1, ficolin-2 and ficolin-3), the key enzymes MASP-2 and MASP-3, and the downstream complement components (C3 fragments and TCC) were present inside and outside brain vessels in all contusions.

Conventional Computed Tomography and Magnetic Resonance in Brain Concussion.

Neuroimaging Clin N Am 2018 Feb 27;28(1):15-29. Epub 2017 Oct 27.

Diagnostic and Interventional Imaging Department, El Bosque University, Hospital Universitario Fundacion Santa Fe de Bogota, Calle 119 # 7 - 75, Bogota DC 110111, Colombia.

Conventional neuroimaging is still the mainstay in the assessment of the acute, follow-up, and chronic settings of concussion and mild traumatic brain injury (mTBI). Computed tomography (CT) is preferred for the initial assessment of acute mTBI, repeat evaluation in acute mTBI with neurologic deterioration, and cautious use in children with mTBI. Clinical rules have been developed to identify pediatric and adult patients with mTBI who can safely forego CT. Read More

Minimizing Retraction by Pia-Arachnoidal 10-0 Sutures in Intrasulcal Dissection.

Oper Neurosurg (Hagerstown) 2018 Jul;15(1):10-14

Department of Neurosurgery, University of Wisconsin-Madison, Madison, Wisconsin.

Background: In contemporary microneurosurgery reducing retraction-induced injury to the brain is essential. Self-retaining retractor systems are commonly used to improve visualization and decrease the repetitive microtrauma, but sometimes self-retaining retractor systems can be cumbersome and the force applied can cause focal ischemia or contusions. This may increase the morbidity and mortality. Read More
