CNS small vessel disease: A clinical review.

CNS small vessel disease (CSVD) causes 25% of strokes and contributes to 45% of dementia cases. Prevalence increases with age, affecting about 5% of people aged 50 years to almost 100% of people older than 90 years. Known causes and risk factors include age, hypertension, branch atheromatous disease, cerebral amyloid angiopathy, radiation exposure, immune-mediated vasculitides, certain infections, and several genetic diseases.

Adult Intestinal Botulism: A Rare Presentation in an Immunocompromised Patient With Short Bowel Syndrome.

The cholinergic heat-labile neurotoxin produced by species is primarily responsible for the clinical manifestations of botulism. The classic phenotypic presentation of botulism consists of subacute descending flaccid paralysis with intact sensory function. Traditionally, it is classified into 3 main forms (foodborne, wound-related, and infantile) on the basis of primary site of toxin entry into the human nervous system.

Reducing Door-to-Reperfusion Time for Mechanical Thrombectomy With a Multitiered Notification System for Acute Ischemic Stroke.

Objective: To reduce door-to-angiographic reperfusion (DTR) time to 120 minutes for patients presenting with acute ischemic stroke attributed to anterior circulation large-vessel occlusion amenable to endovascular mechanical thrombectomy.

Patients And Methods: Patients treated with mechanical thrombectomy before (April 10, 2015, through April 11, 2016) and after (April 12, 2016, through May 10, 2017) implementation of a multitiered notification system were studied. Lean process mapping was used to assess inefficiencies with multidisciplinary triage.

The Clinical Dilemma of Anticoagulation Use in Patients with Cerebral Amyloid Angiopathy and Atrial Fibrillation.

Purpose Of Review: This review highlights current management of patients with concomitant cerebral amyloid angiopathy (CAA) and atrial fibrillation (AF). We review quantifying risk of ischemic and hemorrhagic stroke as well as treatments to minimize future risk.

Recent Findings: Ischemic stroke risk in AF can be quantified by CHADS-VASc and assessing left atrial echocardiographic characteristics.

Brachiocephalic Arterial Occlusive Disease Presenting as Limb-Shaking Transient Ischemic Attacks.

Limb-shaking transient ischemic attacks (LSTIAs) are a phenomenon that occurs due to transient hypoperfusion to a cerebral motor territory with a chronically outstripped autoregulatory vascular reserve. First described in 1962 by Miller Fisher, the pathogenesis and the global understanding of this presentation have undergone a significant advancement throughout the years. Typically, patients will present with this syndrome of transient hypoperfusion in the context of extracranial carotid intrinsic vessel stenosis or by intracranial vascular stenosis to select motor pathways.
