Review Case Reports
Recurrent Cardiogenic Shock Associated with Cannabis Use: Report of a Case and Review of the Literature.
The United States has recently undergone increases in the legalization and use of marijuana. There have been previous reports on the association of cannabis use and myocardial dysfunction, however, few on the association with acute stress cardiomyopathy and cardiogenic shock. ⋯ This is a case of a 58-year-old female with a history of inhaled cannabis use, no history of diabetes, and no known history of cardiac disease, that illustrates an association between cannabis use and the recurrent development of stress cardiomyopathy and cardiogenic shock. A review of medical records was performed from two hospitalizations and subsequent outpatient follow-up for similar presentations 6 years apart and review of literature regarding cannabis use and its association with cardiac dysfunction. In separate hospitalizations, the patient presented with clinical findings of cardiogenic shock, severe left ventricular dysfunction with morphologic features of stress cardiomyopathy, and normal coronary angiography. Laboratory results included elevated cardiac biomarkers and urine tetrahydrocannabinol levels > 300 ng/mL. The patient required intensive cardiovascular support, but recovered with normal cardiac function after each event. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: As use of cannabis becomes more prevalent, it will be important for physicians to recognize the potential association of cannabis use and acute myocardial dysfunction, and how early treatment may contribute to salutary outcomes.

Randomized Controlled Trial
Intranasal Sufentanil Versus Intravenous Morphine for Acute Pain in the Emergency Department: A Randomized Pilot Trial.
Patients in the United States frequently seek medical attention in the emergency department (ED) to address their pain. The intranasal (i.n.) route provides a safe, effective, and painless alternative method of drug administration. Sufentanil is an inexpensive synthetic opioid with a high therapeutic index and rapid onset of action, making it an attractive agent for management of acute pain in the ED. ⋯ The use of i.n. sufentanil at 0.7 μg/kg/dose resulted in rapid and safe analgesia with comparable efficacy to i.v. morphine for up to 30 min in patients who presented with acute pain in the ED.

In the midst of a nationwide opioid epidemic, focus has been placed on identifying and utilizing safe, effective opioid-free analgesic alternatives. Lower-extremity peripheral nerve blockades are common and often involve both motor and sensory anesthesia, resulting in leg weakness and ambulatory difficulty. The aim of this case report is to describe an ultrasound-guided peripheral nerve block technique (superficial cutaneous anesthesia in a lateral (leg) distribution within the emergency department ['SCALD-ED' block]) that provides motor-sparing, purely sensory anesthesia after a superficial injury to the lateral leg in patients presenting to the emergency department. ⋯ The LSCN is an identifiable target under ultrasound guidance, susceptible to localized, purely sensory blockade of pain from superficial cutaneous lateral leg injuries.

Case Reports
Uterine Artery Pseudoaneurysm: A Life-Threatening Cause of Vaginal Bleeding in the Emergency Department.
Vaginal bleeding is a common presenting complaint in the emergency department (ED); life-threatening hemorrhage is rare. Uterine artery pseudoaneurysm (UAP) is an uncommon but potentially life-threatening cause of vaginal bleeding that is most likely to present primarily to EDs, given its delayed postpartum or postoperative presentation. ⋯ A 25-year-old female gravida two, para one, who was 19 days post dilation and evacuation for an elective termination of a pregnancy at 20 weeks, presented to the ED with profuse vaginal bleeding. She was hypotensive and tachycardic at presentation, requiring resuscitation with 0.9% normal saline and transfusions of packed red blood cells. Transvaginal ultrasound completed in the ED demonstrated a pulsatile mass in the cervix with internal "ying-yang" flow on Doppler images, suggestive of a uterine artery pseudoaneurysm within the cervix. The patient underwent emergent uterine artery embolization with resolution of bleeding and improvement in her hemodynamic status. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: UAP is an uncommon cause of vaginal bleeding, but UAP rupture can be life-threatening. UAP is an important differential diagnosis for vaginal bleeding, particularly in the postpartum or postoperative setting. Delaying diagnosis may worsen bleeding in the setting of a ruptured UAP if treatment is pursued for alternative diagnosis; for example, treating retained products of conception with a dilation and curettage. Being aware of UAP and how to diagnose it will allow early proper treatment and more favorable patient outcomes.

One of the hardest decisions a medical student has to make is the choice of specialty. Many studies have explored what influences the choice of emergency medicine (EM) as a specialty. In this article, we elaborate on the most important incentives, including the diversity in patients' presentations, having a defined and flexible schedule, the plasticity in choosing and changing a practice location, and the acuity of care and trauma experience. ⋯ For instance, having to follow a different thought process than most other physicians, as well as the patients' quality and expectations. We also address some of the concerns regarding the specialty, specifically burnout, stress, and the fear associated with maintaining a career in EM. Finally, we provide students interested in EM with some resources that can provide them with further guidance to decide whether EM is the right choice for them.
