A 69-year-old man presented to the emergency department with hematemesis, hypotension, tachycardia, and hypothermia. The emergency physician performed a bedside ultrasound of the chest, heart, and abdomen. The heart was unable to be visualized in the parasternal, apical, or subxiphoid windows, and free fluid and particulate matter were visualized in the chest and abdomen. ⋯ The presence of air in the pericardial sac results in nonvisualization of the heart on ultrasound. Fluid in the chest and abdomen may be visualized in the posterior upper abdominal windows. Although these ultrasound findings alone are not entirely specific for esophageal perforation, when coupled with a high index of suspicion due to the patient presentation, ultrasound can be one of the most portable, readily available, low-cost, and minimally invasive techniques to make the diagnosis of esophageal perforation.

In minor cases, contrast extravasation may cause pain, swelling, and localized erythema. However, in more severe cases, extensive tissue and skin necrosis, ulceration, and compartment syndrome may occur, often necessitating a surgical consultation. Hyaluronidase has been used successfully in the management of extravasated contrast media in several reports. ⋯ In a follow-up 4 hours later, marked improvement was observed. Sixteen hours after hyaluronidase treatment, the tissue had reverted to a near-normal state with no pain, erythema, swelling, or tenderness noted. Hyaluronidase successfully treated this extravasation of a large volume of iodinated contrast and appears to be a reasonable treatment option for more extensive subcutaneous contrast media extravasations.

A seminal vesicle cyst is a rare etiology of pelvic pain. However, its rarity may result in oversight or misinterpretation if the radiologist or emergency physician is unfamiliar with this entity. Seminal vesicle cysts may cause pelvic pain because of mass effect, infection, internal hemorrhage, or urinary and bladder obstruction. ⋯ Recognition of the imaging findings of seminal vesicle cysts is necessary to allow prompt, accurate diagnosis. Therefore, emergency physicians and radiologists interpreting examinations from the emergency department should be familiar with these imaging findings because seminal vesicle cysts may be the etiology of pelvic pain and the patient may benefit from urologic consultation and cyst aspiration or resection. The purposes of this article are to provide examples of pelvic pain caused by seminal vesicle cysts, illustrate the key imaging findings on computed tomography, and briefly review the literature.

Our objective was to identify demographic, clinical, and operational variables associated with discrepancy between point-of-care (POC) and central laboratory international normalized ratio (INR) results in emergency department (ED) patients with acute cerebrovascular disease. ⋯ In this retrospective study, oral anticoagulant use and increasing aPTT were significantly associated with POC INR discrepancy in ED patients with acute cerebrovascular disease. Point-of-care INR discrepancy incidence decreased over the study interval.

The aim of this study was to investigate the clinical characteristics of anaphylactic shock and the factors associated with anaphylactic shock in anaphylaxis. ⋯ Elderly anaphylactic patients with symptoms of cyanosis, syncope, and dizziness were at increased risk for the development of shock. Physicians in the ED have to be alert to the possibility of progression to shock in patients with anaphylaxis, and early recognition of anaphylactic shock is critical for adequate treatment.
