Department of Emergency Medicine Faculty Papers

BACKGROUND: Accurate recognition of stroke symptoms by Emergency Medical Services (EMS) is necessary for timely care of acute stroke patients. We assessed the accuracy of stroke diagnosis by EMS in clinical practice in a major US city.

METHODS AND RESULTS: Philadelphia Fire Department data were merged with data from a single comprehensive stroke center to identify patients diagnosed with stroke or TIA from 9/2009 to 10/2012. Sensitivity and positive predictive value (PPV) were calculated. Multivariable logistic regression identified variables associated with correct EMS diagnosis. There were 709 total cases, with 400 having a discharge diagnosis of stroke or TIA. EMS …

Brain-derived neurotrophic factor (BDNF), a key player in regulating synaptic strength and learning, is dysregulated following traumatic brain injury (TBI), suggesting that stimulation of BDNF signaling pathways may facilitate functional recovery. This study investigates whether CN2097, a peptidomimetic ligand which targets the synaptic scaffold protein, postsynaptic density protein 95, to enhance downstream signaling of tropomyosin-related kinase B, a receptor for BDNF, can improve neurological function after TBI. Moderate to severe TBI elicits neuroinflammation and c-Jun-N-terminal kinase (JNK) activation, which is associated with memory deficits. Here we demonstrate that CN2097 significantly reduces the post-traumatic synthesis of proinflammatory mediators and inhibits the …

Self‑Resolving Prepontine Cyst, Muhammad Waqas, Inamullah Khan, Reehana Khawaja, Ayesha Quddusi, Ather Enam

Section of Neurosurgery

Background: Intracranial prepontine cysts are rare and include epidermoid cysts, arachnoid cysts, and neurenteric cysts. Symptomatic prepontine cysts may require surgical intervention. Reports of spontaneous resolution of cysts are rare.
Case description: We describe the case of a young gentleman who presented with headache and fever. Magnetic resonance imaging of the brain identified a prepontine lesion with features consistent with epidermoid cyst. During admission, the patient received symptomatic management in addition to empirical antibiotic therapy and dexamethasone. The patient improved symptomatically in the next 48 hours and was discharged. Follow-up imaging at 6 months and 1 year showed significant reduction …

Application Of Rns In Refractory Epilepsy: Targeting Insula., Hai Chen, Patricia Dugan, Derek J Chong, Anli Liu, Werner Doyle, Daniel Friedman

Neurology Faculty Publications

Although responsive neurostimulation (RNS) is approved for treatment of resistant focal epilepsy in adults, little is known about response to treatment of specific cortical targets. We describe the experience of RNS targeting the insular lobe. We identified patients who had RNS implantation with at least one electrode within the insula between April 2014 and October 2015. We performed a retrospective review of preoperative clinical features, imaging, electrocardiogram (EEG), intraoperative electrocorticography (ECoG), and postoperative seizure outcome. Eight patients with at least 6 months of postimplant follow-up were identified. Ictal localization was inconclusive with MRI or scalp EEG findings. Intracranial EEG monitoring …

Hemimegalencephaly With Intractable Epilepsy: A Case Report, Prem Chand, Muhammad Faraz Raghib, Muhammad Sohail Salat

Department of Paediatrics and Child Health

Isolated Hemimegalencephaly (iHME) is a rare form of congenital malformation of cortical development.It is characterized by enlargement of all or part of one cerebral hemisphere. It typically presents with intractable seizures, mental retardation, developmental delay, contralateral hemiparesis and hemianopia. The patient was a five and half month's old baby girl who presented first with focal seizures at 10th day of life. No other physical or behavioral abnormality was noted. However, Initial EEG showed excessive sharp EEG transients more over the right hemisphere, repeated EEG showed spikes, polyspikes, sharps and slow wave discharges predominately over right hemisphere. MRI brain showed asymmetric …

Brain Injury-Induced Synaptic Reorganization In Hilar Inhibitory Neurons Is Differentially Suppressed By Rapamycin, Corwin R. Butler, Jeffery A. Boychuk, Bret N. Smith

Physiology Faculty Publications

Following traumatic brain injury (TBI), treatment with rapamycin suppresses mammalian (mechanistic) target of rapamycin (mTOR) activity and specific components of hippocampal synaptic reorganization associated with altered cortical excitability and seizure susceptibility. Reemergence of seizures after cessation of rapamycin treatment suggests, however, an incomplete suppression of epileptogenesis. Hilar inhibitory interneurons regulate dentate granule cell (DGC) activity, and de novo synaptic input from both DGCs and CA3 pyramidal cells after TBI increases their excitability but effects of rapamycin treatment on the injury-induced plasticity of interneurons is only partially described. Using transgenic mice in which enhanced green fluorescent protein (eGFP) is expressed in …

A Clinical Practice Guideline For The Management Of Acute Spinal Cord Injury: Introduction, Rationale, And Scope, Michael G. Fehlings, Lindsay A. Tetreault, Jefferson R. Wilson, Brian K. Kwon, Anthony S. Burns, Allan R. Martin, Gregory Hawryluk, James S. Harrop

Department of Neurosurgery Faculty Papers

Acute spinal cord injury (SCI) is a traumatic event that results in disturbances to normal sensory, motor, or autonomic function and ultimately affects a patient’s physical, psychological, and social well-being. The management of patients with SCI has drastically evolved over the past century as a result of increasing knowledge on injury mechanisms, disease pathophysiology, and the role of surgery. There still, however, remain controversial areas surrounding available management strategies for the treatment of SCI, including the use of corticosteroids such as methylprednisolone sodium succinate, the optimal timing of surgical intervention, the type and timing of anticoagulation prophylaxis, the role of …

Neurological Disorder Burden In Faisalabad, Punjab-Pakistan:Data From The Major Tertiary Carecenters Of The City, Ghulam Hussain, Asif Shahzad, Haseeb Anwar, Shahid Mahmood Baig, Asghar Shabbir, Jose-Luis Gonzalez De Aaguilar

Pakistan Journal of Neurological Sciences (PJNS)

The burden of neurological disorders (NDs) in developing countries is 4-5%, compared to 10-11% in developed countries. This burden is rising in developing countries due to prolonged life expectancy, improved health facilities, easy access to diagnostic facilities, and a trend in urbanization. There is inadequate data about the epidemiology of major NDs in Pakistan and most available information are hospital-based estimations or physicians’ collected data.

The Rna-Binding Protein Hur Contributes To Neuroinflammation By Promoting C-C Chemokine Receptor 6 (Ccr6) Expression On Th17 Cells., Jing Chen, Jennifer L. Martindale, Carole Cramer, Myriam Gorospe, Ulus Atasoy, Paul D. Drew, Shiguang Yu

Department of Neurology Faculty Papers

In both multiple sclerosis and experimental autoimmune encephalomyelitis (EAE), the C-C chemokine receptor 6 (CCR6) is critical for pathogenic T helper 17 (Th17) cell migration to the central nervous system (CNS). Whereas many cytokines and their receptors are potently regulated via post-transcriptional mechanisms in response to various stimuli, how CCR6 expression is post-transcriptionally regulated in Th17 cells is unknown. Here, using RNA-binding protein HuR conditional knock-out (KO) and wild-type (WT) mice, we present evidence that HuR post-transcriptionally regulates CCR6 expression by binding to and stabilizing Ccr6 mRNA and by promoting CCR6 translation. We also found that HuR down-regulates several microRNA …
