Teleneurology via tablet technology: an effective low-cost method to increase healthcare accessibility.

Introduction: Telemedicine is a valuable tool to increase access to health care, especially for patients in rural areas who need to visit a specialist. In place of telemedicine robots, which are costly and complicated, hospitals have implemented successful telemedicine programs using lower-cost tablet technology; opting for tablet technology increases the organizational feasibility of a large-scale telemedicine program.

Methods: Vanderbilt University Medical Center (VUMC), in Nashville, Tennessee, USA, launched its teleneurology network program in 2014 to serve patients in surrounding community hospitals who needed a neurology consult.

Thrombolytic therapy for wake-up stroke: A systematic review and meta-analysis.

Background And Purpose: According to evidence-based clinical practice guidelines, patients presenting with disabling stroke symptoms should be treated with intravenous tissue plasminogen activator (IV tPA) within 4.5 h of time last known well. However, 25% of strokes are detected upon awakening (i.

IgG4-related disease: Association with a rare gene variant expressed in cytotoxic T cells.

Background: Family screening of a 48-year-old male with recently diagnosed IgG4-related disease (IgG4-RD) revealed unanticipated elevations in plasma IgG4 in his two healthy teenaged sons.

Methods: We performed gene sequencing, immune cell studies, HLA typing, and analyses of circulating cytotoxic CD4+ T lymphocytes and plasmablasts to seek clues to pathogenesis. DNA from a separate cohort of 99 patients with known IgG4-RD was also sequenced for the presence of genetic variants in a specific gene, FGFBP2.

Teleneurology service provided via tablet technology: 3-year outcomes and physician satisfaction.

Introduction: This study aimed to demonstrate that teleneurology consultations conducted via tablet technology are an efficient and cost-effective means of managing acute neurologic emergencies at community-based hospitals and that utilizing such technology yields high community physician satisfaction.

Method: During a 39-month period, Vanderbilt University Medical Center in Tennessee USA, provided teleneurology services to 10 community-based hospitals that lacked adequate neurology coverage. Hospitalists at one community-based hospital were not comfortable treating any patient with a neurologic symptom, resulting in 100% of those patients being transferred.

Implementation of an institution-wide acute stroke algorithm: Improving stroke quality metrics.

Background: In May 2012, an updated stroke algorithm was implemented at Vanderbilt University Medical Center. The current study objectives were to: (1) describe the process of implementing a new stroke algorithm and (2) compare pre- and post-algorithm quality improvement (QI) metrics, specificaly door to computed tomography time (DTCT), door to neurology time (DTN), and door to tPA administration time (DTT).

Methods: Our institutional stroke algorithm underwent extensive revision, with a focus on removing variability, streamlining care, and improving time delays.

Routine clinical evaluation of cerebrovascular reserve capacity using carbogen in patients with intracranial stenosis.

Background And Purpose: A promising method for identifying hemodynamic impairment that may serve as a biomarker for stroke risk in patients with intracranial stenosis is cerebrovascular reactivity (CVR) mapping using noninvasive MRI. Here, abilities to measure CVR safely in the clinic using hypercarbic hyperoxic (carbogen) gas challenges, which increase oxygen delivery to tissue, are investigated.

Methods: In sequence with structural and angiographic imaging, blood oxygenation level-dependent carbogen-induced CVR scans were performed in patients with symptomatic intracranial stenosis (n=92) and control (n=10) volunteers, with a subgroup of patients (n=57) undergoing cerebral blood flow-weighted pseudocontinuous arterial spin labeling CVR.

Vascular complications of fungal meningitis attributed to injections of contaminated methylprednisolone acetate.

Importance: Fungal meningitis due to injections of contaminated methylprednisolone acetate can present with vascular sequelae in immunocompetent individuals. This is particularly germane to neurologists because better recognition of the clinical characteristics of patients with fungal meningitis and ischemic stroke will provide more timely and efficient care.

Observations: In a case series, 3 patients presented to Vanderbilt University Medical Center in Nashville, Tennessee, with acute ischemic stroke and later received a diagnosis of fungal meningitis attributed to epidural injections of contaminated methylprednisolone.
