Admission rates of ED patients with transient ischemic attack have increased since 2000
This study is conducted in 6 New Jersey EDs with annual ED visits from 25000 to 65000. Consecutive patients seen by ED physicians between January 1, 2000, and December 31, 2010, were included. We identified TIA visits using the International Classification of Diseases, Ninth Revision, code. We analyzed the admission rates for TIA testing for significant differences using the Student t test and calculated 95% confidence intervals.Results: Of the 2622659 visits in the database, 8216 (0.3%) were for TIA. Females comprised 57%. There was a statistically significant increase in the annual admission rates for TIA patients from 2...

Simultaneous thrombosis of 2 vascular territories: is thrombolytic therapy a better option?
We have read with great interest the article by Akyuz and colleagues in the American Journal of Emergency Medicine and congratulate them for their observation. Their case exemplifies the concurrent occurrence of ST-segment elevation myocardial infarction (STEMI) and posterior circulation stroke that was eventually managed with thrombolytic therapy. Simultaneous thrombosis of 2 distant vascular territories is a rare and complicated clinical scenario. In these instances, there is usually an underlying cause linking both thrombotic events rather than being a mere coincidence. We have previously described the myocardial infarc...

Isolated basilar artery dissection—a rare cause of stroke in young adult
Syncope accounts for approximately 1% to 2% of emergency department visits each year and up to 6% of hospital admissions . The causes of syncope are numerous, from common benign disorders to life-threatening processes including transient ischemic attack and even stroke. Although cervicocerebral artery dissection is an uncommon etiology in ischemic stroke, it is the second leading cause in patients younger than 45 years, and most of them predominantly involved the extracranial artery . Dissections of intracranial arteries are increasingly being recognized with advanced imaging study; however, isolated basilar artery dissect...

Troponin rise and poor outcome in patients with acute atrial fibrillation: rationale and criteria of selection of patients
The role of new onset atrial fibrillation (AF) as a marker of thromboembolic risk has been demonstrated in the setting of acute myocardial infarction . Thus, someone might inquire the role of acute AF in patients with abnormal troponin not fulfilling criteria of acute myocardial infarction and might question if the minor reported range of troponin I (cTn-I) values in the study population of Conti et al (from 0.15 to 7.0 ng/mL) may not be linked with a secondary ischemic mechanism, likely an imbalance between demand and supply . However, the independent predictive value of abnormal troponin for a composite of stroke, acute ...

Lung transplant of extrahospitalary donor after cardiac death
The objective of this study is to describe the results of lung transplantation of after cardiac death program, specifically the section regarding lung extraction donation. Twenty potential lung donors were obtained during the study. Most patients were male (19 cases), with a mean age of 42 years (36.5-49.5 years). A total of 33 lungs were donated (18 right and 15 left lungs). Most extractions were multiorganic (19 cases). One liver, 19 kidneys, 2 pancreas, and 19 corneas were obtained from these donors; bone tissue was obtained from all donors. The transplantation was bipulmonary in 13 cases and unipulmonary in 7. Thirty d...

Factors associated with use of emergency medical services in patients with acute stroke
Abstract: Purposes: The aim of this study was to investigate the factors associated with use of emergency medical services (EMS) in patients with acute stroke.Methods: Prospective data on consecutive patients with acute stroke who presented to the emergency department of a university medical center from January 1, 2010, to July 31, 2011, were analyzed. Patients were excluded if they had an unknown residence, had onset of stroke at a nursing home or hospital, or were transferred from another hospital. Variables for all patients with stroke and ischemic stroke who did and did not use EMS were compared.Results: In total, 1344...

Abnormal troponin level as short-term predictor of poor outcome in acute atrial fibrillation
Abstract: Background: The link between minor troponin (cardiac troponin I [cTnI]) elevations and atrial fibrillation (AF) is still debated.Methods: A total of 948 patients with AF lasting less than 48 hours participated in the study and were required to undergo 1-month and 12-month follow-up. The exclusion criteria were represented by younger than 18 years, the presence of hemodynamic instability, or severe comorbidity. Primary end point was the composite of ischemic vascular events inclusive of stroke, acute coronary syndrome, revascularization, and death.Results: In the short term, 4 patients (5%) of 78 with abnormal cTn...

Subconjunctival hemorrhage in a patient on dabigatran (Pradaxa)
Dabigatran is a direct thrombin inhibitor that has gained increasing popularity for prevention of thromboembolic events such as stroke, pulmonary embolism, and myocardial ischemia. Because of the increasing use of this drug, emergency department (ED) physicians are going to be evaluating patients taking this medication. It is important to understand the potential for ocular bleeding complications associated with this class of anticoagulant. Traditionally, patients have been placed on vitamin K antagonists to decrease the risk of thromboembolism. In the RE-LY and RE-COVER studies, dabigatran showed non-inferiority to coumad...
