Massive Bleeding From Inferior Mesenteric Vein With Hypovolemic Shock: A Rare Complication of Acute Pancreatitis.
Acute pancreatitis may cause massive intra-abdominal bleeding as vascular complications caused by the erosion of a major pancreatic or peripancreatic vessel. In terms of treatment, the differentiation between arterial bleeding and venous bleeding using abdominal computed tomography (CT) angiography is important. In addition, hypovolemic shock caused by bleeding from the inferior mesenteric vein (IMV) in acute pancreatitis has not been reported. ⋯ A 58-year-old man presented to our emergency department with complaints of abdominal pain of 10 hours' duration. The pain had an abrupt onset and started with alcohol consumption. After performing initial laboratory tests and an abdominal CT scan, he was diagnosed with acute pancreatitis. However, he complained of severe abdominal pain and was drowsy 2 h later. Follow-up CT angiography revealed acute necrotizing pancreatitis with massive hemoperitoneum and hypovolemic shock. We also found active bleeding from the IMV. We did not consider emergency catheter angiography with embolization; instead, exploratory laparotomy and hematoma evacuation with IMV ligation was performed. He was discharged without complications 14 days later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Massive bleeding from the IMV accompanied by shock bowel syndrome is a rare complication of acute pancreatitis that can be confused with arterial bleeding. Emergency physicians should consider this diagnosis in acute pancreatitis as a possible cause of hypovolemic shock and anatomic course of the IMV and prevent fulminant shock by administering appropriate treatment.

A troponin assay is commonly sent for patients presenting to emergency departments (EDs) with supraventricular tachycardia (SVT). Multiple studies suggest that elevated troponin levels do not predict coronary artery disease in these patients. Patients with elevated troponins are more likely to have additional cardiac testing, which can lead to increased health care costs and unnecessary invasive procedures. ⋯ Patients with a positive troponin result had significantly more admissions, cardiology consults, and longer hospital stays. These patients did not have an increased prevalence of MACE.

Observational Study
Opioid Prescribing: Where Should Academic Emergency Departments Focus Their Efforts?
Opioid prescriptions from the emergency department (ED) are being heavily scrutinized. This has resulted in prescribing guidelines and laws. ⋯ EM providers prescribe short courses of opiates regardless of postgraduate year. Patients returning to the ED received fewer pills on subsequent visits. Non-EM providers prescribe larger numbers of pills per prescription. This information will help focus future operational efforts and educational efforts to comply with guidelines and laws.

Although use of the superficial cervical plexus block (SCPB) by anesthesia for perioperative indications is well described, there is a paucity of research on use of SCPB in the emergency department (ED). ⋯ While limited by the fact that this was a nonrandomized observational experience with no control group, our findings suggest that SCBP may be safe and have potential for efficacy, and warrants further evaluation in a randomized controlled trial.

Case Reports
Man with a Swollen Eye: Nonspecific Orbital Inflammation in an Adult in the Emergency Department.
Nonspecific orbital inflammation (NSOI) is a rare idiopathic ocular pathology characterized by unilateral, painful orbital swelling without identifiable infectious or systemic disorders, which can be complicated by optic nerve compromise. ⋯ A 50-year-old man presented to the Emergency Department with recurring, progressive painless left eye swelling, decreased visual acuity, and binocular diplopia in the absence of trauma, infection, or known malignancy. His physical examination was notable for left-sided decreased visual acuity, an afferent pupillary defect, severe left eye proptosis and chemosis, and restricted extraocular movements; his dilatated funduscopic examination was notable for ipsilateral retinal folds within the macula, concerning for a disruption between the sclera and the retina. Ocular examination of the right eye was unremarkable. Laboratory data were unrevealing. Gadolinium-enhanced magnetic resonance imaging showed marked thickening of the left extraocular muscles associated with proptosis, dense inflammatory infiltration of the orbital fat, and characteristics consistent with perineuritis. The patient was diagnosed with NSOI with optic neuritis and admitted for systemic steroid therapy; he was discharged on hospital day 2 after receiving high-dose intravenous (i.v.) methylprednisolone with significant improvement. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: NSOI is a rare and idiopathic ocular emergency, with clinical mimicry resembling a broad spectrum of systemic diseases such as malignancy, autoimmune diseases, endocrine disorders, and infection. Initial work-up for new-onset ocular proptosis should include comprehensive laboratory testing and gadolinium-enhanced magnetic resonance imaging. Timely evaluation by an ophthalmologist is crucial to assess for optic nerve involvement. Signs of optic nerve compromise include decreased visual acuity, afferent pupillary defect, or decreased color saturation. Patients with optic nerve compromise require admission for aggressive anti-inflammatory therapy with i.v. steroids in an attempt to reduce risk of long-term visual sequelae. Our case demonstrates a severe presentation of this disorder and exhibits remarkable visual recovery after 48 h of systemic i.v. steroid treatment.
