Takayasu’s Arteritis – An Unusual Cause of Stroke in a Young Patient

We describe the case of a 28-year-old-male with no significant medical history who presented with right-sided hemiparesis, bruits over the carotid and subclavian arteries and an elevated erythrocyte sedimentation rate. Imaging studies revealed a middle cerebral artery thrombus and inflammatory changes of the carotid and subclavian arteries and aorta. The diagnosis of Takayasu’s arteritis was made and the patient was started on steroids and immunomodulators with good clinical response.

The Impact of Cardiac Contractility on Cerebral Blood Flow in Ischemia

In cerebral regions affected by ischemia, intrinsic vascular autoregulation is often lost. Blood flow delivery depends upon cardiac function and may be influenced by neuro-endocrine mediated myocardial suppression. Our objective is to evaluate the relation between ejection fraction (EF) and transcranial doppler (TCD) peak systolic velocities (PSV) in patients with cerebral ischemic events.

Contagious Weakness in an Elderly Couple with Neurologic Emergencies

We present an unusual neurologic emergency in an elderly male patient. Given his presentation and risk factors, we presumed the initial symptoms to be secondary to a cerebrovascular accident. As the case evolved, however, it became apparent that a more unusual pathology was present. This case report showcases a rare condition masquerading as a common neurologic emergency.

Lidocaine Toxicity Misinterpreted as a Stroke

For more than 50 years lidocaine has been used to treat ventricular arrhythmias. Neurologic dysfunction, manifested as a stroke, occurred acutely in an 87-year-old woman after she had been administered repeated doses of lidocaine, a lidocaine infusion, then an intravenous amiodarone infusion for ventricular tachycardia. This was ultimately diagnosed as lidocaine toxicity with a serum lidocaine level of 7.9 mg/L (1.5–6.0 mg/L). We discuss lidocaine toxicity and risk factors leading to its development, which include particularly hepatic dysfunction, cardiac dysfunction, advanced age and other drug administration.

Acute Ischemic Stroke in a Pediatric Patient

Acute ischemic stroke in a pediatric patient is a complex disease with a variety of etiologies that differ from adults. Though rare, they are a real phenomenon with potentially devastating consequences. Some treating institutions are using anti-thrombotic drug therapy with unclear benefits. Available literature, which is limited to case reports and retrospective reviews of databases, clouds this topic with both positive and negative outcomes. Emergency department management should focus on stabilization and resuscitation with immediate involvement of a pediatric neurologist and intensivist. The decision to use anti-thrombotic drug therapy, including anti-platelet drugs and thrombolytics, should be in consult with the specialists involved until randomized controlled trials determine their safety and efficacy in the pediatric population.

Our Philosophy

Emergency Medicine is a specialty which closely reflects societal challenges and consequences of public policy decisions. The emergency department specifically deals with social injustice, health and economic disparities, violence, substance abuse, and disaster preparedness and response. This journal focuses on how emergency care affects the health of the community and population, and conversely, how these societal challenges affect the composition of the patient population who seek care in the emergency department. The development of better systems to provide emergency care, including technology solutions, is critical to enhancing population health.
