Comprehensive Review Of Spinal Neurenteric Cysts With A Focus On Histopathological Findings., Woong Kee Baek, Stefan Lachkar, Joe Iwanaga, Rod J Oskouian, Marios Loukas, W Jerry Oakes, R Shane Tubbs
Articles, Abstracts, and Reports
Among the occult spinal dysraphisms, neurenteric cysts (NECs) are rare and are thought to arise due to a failure of the separation of the primitive endoderm and ectoderm. Patients experience various neurological symptoms depending on the location of the lesion. As the epithelial morphology of NECs share similarities with other intracranial and intraspinal cystic growths, the definitive diagnosis of NEC can be made after a histochemical analysis with endodermal markers. Complete resection is associated with the lowest disease recurrence rate.

Section of Neurosurgery
Background: Worldwide, traumatic brain injury (TBI) kills or hospitalises over 10 million people each year. Early intracranial bleeding is common after TBI, increasing the risk of death and disability. Tranexamic acid reduces blood loss in surgery and death due to bleeding in trauma patients with extra-cranial injury. Early administration of tranexamic acid in TBI patients might limit intracranial bleeding, reducing death and disability. The CRASH-3 trial aims to provide evidence on the effect of tranexamic acid on death and disability in TBI patients. We will randomly allocate about 13,000 TBI patients (approximately 10,000 within 3 hours of injury) to an …

Generating a comprehensive description of cortical networks requires a large-scale, systematic approach. To that end, we have begun a pipeline project using multipatch electrophysiology, supplemented with two-photon optogenetics, to characterize connectivity and synaptic signaling between classes of neurons in adult mouse primary visual cortex (V1) and human cortex. We focus on producing results detailed enough for the generation of computational models and enabling comparison with future studies. Here, we report our examination of intralaminar connectivity within each of several classes of excitatory neurons. We find that connections are sparse but present among all excitatory cell classes and layers we sampled, …

Articles, Abstracts, and Reports
The anterior communicating artery is one of the main components of the vascular network that delivers blood to the brain. Therefore, a good understanding of the normal anatomy and its variations is important to neurologists, neurosurgeons, and other health care providers dealing with the central nervous system. Here, we present a case of a median artery of the corpus callosum found in a cadaver, with consideration of cerebral hemodynamics implications.

Muscle spindles and Golgi tendon organs (GTOs) are two types of sensory receptors that respond to changes in length or tension of skeletal muscles. These mechanosensors have long been known to participate in both proprioception and stretch reflex. Here, we present recent findings implicating these organs in maintenance of spine alignment as well as in realignment of fractured bones. These discoveries have been made in several mouse lines lacking functional mechanosensors in part or completely. In both studies, the absence of functional spindles and GTOs produced a more severe phenotype than that of spindles alone. Interestingly, the spinal curve phenotype, …

Astrocyte Activation And The Calcineurin/Nfat Pathway In Cerebrovascular Disease, Susan D. Kraner, Christopher M. Norris
Sanders-Brown Center on Aging Faculty Publications
Calcineurin (CN) is a Ca2+/calmodulin-dependent protein phosphatase with high abundance in nervous tissue. Though enriched in neurons, CN can become strongly induced in subsets of activated astrocytes under different pathological conditions where it interacts extensively with the nuclear factor of activated T cells (NFATs). Recent work has shown that regions of small vessel damage are associated with the upregulation of a proteolized, highly active form of CN in nearby astrocytes, suggesting a link between the CN/NFAT pathway and chronic cerebrovascular disease. In this Mini Review article, we discuss CN/NFAT signaling properties in the context of vascular disease and …

Neurological Complications Of Immune Checkpoint Inhibitors: What Happens When You 'Take The Brakes Off' The Immune System., Marinos Dalakas
Department of Neurology Faculty Papers
Patients with advanced malignancies treated with immune checkpoint inhibitors are at increased risk for developing immune-related neurological complications. It is a phenomenon of immunological twist when immunotherapy against co-stimulatory molecules activates previously normal T cells to kill tumor cells but, in so doing, the T cells become unrestrained, triggering other autoimmune diseases for which conventional immunotherapy is needed. The most common autoimmune neurological diseases, usually occurring within 2-12 weeks after immune checkpoint inhibitor initiation, include: inflammatory myopathies, myasthenia gravis, acute and chronic demyelinating polyradiculoneuropathies, vasculitic neuropathies, isolated cranial neuropathies, aseptic meningitis, autoimmune encephalitis, multiple sclerosis and hypophysitis. The neurological events …

Large goiters are less common in the developing world due to the use of iodized salt. However, these are seen occasionally. Herein, we report a case of very large goiter identified in a cadaver. This case is also of interest due to the significant lateral displacement of the common carotid arteries (CCA) and the midline shift of the trachea. This case and the salient literature addressing this topic have been discussed.

The dearth of effective treatments for Alzheimer’s disease (AD) is one of the largest public health issues worldwide, costing hundreds of billions of dollars per year. From a therapeutic standpoint, research efforts to date have met with strikingly little clinical success. One major issue is that trials begin after substantial pathological change has occurred, and it is increasingly clear that the most effective treatment regimens will need to be administered earlier in the disease process. In order to identify individuals within the long preclinical phase of AD who are likely to progress to dementia, improvements are required in biomarker development. …

Articles, Abstracts, and Reports
The dural venous sinuses are venous channels in the cranium that drain blood and cerebrospinal fluid circulating from the brain into the vascular system via the internal jugular veins. The transverse sinus is a dural venous sinus present in the posterior aspect of the cranium. We report an unusual variant of this sinus with the presence of a fenestration at its proximal segment. We will review and discuss the background and the potential clinical relevance of this anatomical variation.

Role Of Palliative Csf Diversion In Patients With Intracranial Metastatic Disease And Symptomatic Hydrocephalus, Farhan A. Mirza, Muhammad Shahzad Shamim
Section of Neurosurgery
Hydrocephalus, unless treated, is one of the terminal manifestations of intracranial metastatic disease. Single lesions causing obstructive hydrocephalus are amenable to surgical resection, but in the setting of multiple lesions and communicating hydrocephalus from leptomeningeal disease, the approach to treatment is much less defined. The use of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunting (VPS) has been described, but data is limited. In this review, we summarize the sparse data available in literature describing the use of CSF diversion for patients with metastatic disease presenting with hydrocephalus and neurological decline.

Articles, Abstracts, and Reports
Numerous types of inhibitory neurons sculpt the performance of human neocortical circuits, with each type exhibiting a constellation of subcellular phenotypic features in support of its specialized functions. Axonal myelination has been absent among the characteristics used to distinguish inhibitory neuron types; in fact, very little is known about myelinated inhibitory axons in human neocortex. Here, using array tomography to analyze samples of neurosurgically excised human neocortex, we show that inhibitory myelinated axons originate predominantly from parvalbumin-containing interneurons. Compared to myelinated excitatory axons, they have higher neurofilament and lower microtubule content, shorter nodes of Ranvier, and more myelin basic protein …

Behavioral Challenges In Childhood Epilepsy, Tipu Sultan
Pakistan Journal of Neurological Sciences (PJNS)
Behavioral problems among children with epilepsy is one of the most common problem. Severity of the problem ranges from 16% to 77% as compared to 9% in the general pediatric population. Such a huge variation in the results reflects probable difference in the methodology. Structured interviews that include parents, children and clinician’s reports have identified a higher rate of behavioral problems when compared to self-report instruments. Higher rates are reported in clinical samples recruited from tertiary care medical centers, where they have a lot of referrals from the peripheral small units. Most researchers agree that children with epilepsy have three …

Low-grade gliomas (LGG) encompass a heterogeneous group of tumors that are clinically, histologically and molecularly diverse. Treatment decisions for patients with LGG are directed toward improving upon the natural history while limiting treatment-associated toxiceffects. Recent evidence has documented a utility for adjuvant chemotherapy with procarbazine, CCNU (lomustine), and vincristine (PCV) or temozolomide (TMZ). We sought to determine the comparative utility of PCV and TMZ for patients with LGG, particularly in context of molecular subtype. A literature search of PubMed was conducted to identify studies reporting patient response to PCV, TMZ, or a combination of chemotherapy and radiation therapy (RT). Eligibility …

Devic’s disease or syndrome also known as Neuromyelitis optica (NMO) which is a demyelinating central nervous system (immune-mediated) ailment that predominantly targets the optic nerves and spinal cord. NMO-IgG seropositivity & longitudinally extensive spinal-cord lesions typically represents the Devic’s disease & differentiates it from Multiple Sclerosis (MS).Treatment for NMO is based upon its presentation such as for acute phase(steroids, IVIG etc), prevention of relapse (steroid sparing immunosuppression etc) and symptom based therapy (e.g spasticity etc). Here, we present a case of NMO in a young female (26 years old), married patient who presented to us with total vision loss, urinary …
