Case Reports
Lev's Syndrome: A rare case of progressive cardiac conduction disorder presenting to the emergency department.
Lev's Syndrome is a rare, progressive cardiac conduction defect (PCCD) due to myocardial fibrosis first described by Maurice Lev in 1964. This condition, proposed to start in the fourth decade of life, involves a sclerotic fibro-fatty degeneration of the Bundle of His and Purkinje fibers, which Lev proposed caused increasing AV delay with age. With the prevalence of electrocardiogram (ECG) use in the emergency department (ED) for cardiac- and non-cardiac complaints, dysrhythmias can be incidentally found and confuse diagnosis and disposition. ⋯ Cardiology was consulted. Serial ECGs demonstrated an evolving conduction block arrhythmia consistent with Lev's Syndrome. Here we describe a case of symptomatic bradycardia found to be consistent with Lev's Syndrome.

We generated a novel scoring system to improve the test characteristics of D-dimer in patients with suspected PE (pulmonary emboli). Electronic Medical Record data were retrospectively reviewed on Emergency Department (ED) patients 18 years or older for whom a D-dimer and imaging were ordered between June 4, 2012 and March 30, 2016. Symptoms (dyspnea, unilateral leg swelling, hemoptysis), age, vital signs, medical history (cancer, recent surgery, medications, history of deep vein thrombosis or PE, COPD, smoking), laboratory values (quantitative D-dimer, platelets, and mean platelet volume (MPV)), and imaging results (CT, VQ) were collected. ⋯ Specificity improved (38% to 59%) without compromising sensitivity (94% to 96%). Use of the DAGMAR Score would have reduced CT scans from 2253 to 1556 and lead to fewer false negative results. By considering factors that affect D-dimer and also PE, we improved specificity without compromising sensitivity.

Case Reports
Traumatic coronary artery dissection leading to ventricular tachycardia: A case report.
Traumatic coronary artery dissection is an unusual injury following trauma. It is potentially life threatening and requires prompt recognition on presentation. We present a case report of a 42-year-old male who presented with ventricular tachycardia following a high-speed motorcycle collision that was found to have a coronary artery dissection. The patient had multiple complications, highlighting the importance of early recognition of this disease process.

Nephrolithiasis is a common pathology encountered in the primary care and emergency department (ED) setting. In 2009 alone, there were over one million ED visits related to nephrolithiasis Higa et al. (2017) [1]. ⋯ There are very few case reports documenting distal urethral stone removal in the ED. Here we present a case of distal urethral stone impaction and the removal of this stone by ED providers, leading to expedited care and prevention of consultation and possible admission.
