Review Case Reports
Carotid Blowout Syndrome in the Emergency Department: A Case Report and Review of the Literature.
Carotid blowout syndrome (CBS) is an infrequent but dangerous oncologic emergency that must be recognized due to a mortality rate that approaches 40% and neurologic morbidity that approaches 60%. Patients present with a variety of symptoms ranging from asymptomatic to frank hemorrhage, and appropriate recognition and management may improve their outcomes. ⋯ A man in his late 60s with squamous cell carcinoma of the oropharynx presented to the emergency department (ED) with hemoptysis and several episodes of post-tussive emesis with large clots. He had been cancer free for multiple years after treatment with chemotherapy and radiation to the neck. Evaluation revealed a necrotic tumor on the posterior pharynx on bedside laryngoscopy and an external carotid pseudoaneurysm that was stented by interventional radiology. The patient experienced recurrent hemorrhage several months later and opted for palliative measures and expired of massive hemorrhage in the ED on a subsequent visit. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: CBS can be fatal, and early suspicion and recognition are key to ensure that a threatened or impending carotid blowout are appropriately managed. Once carotid blowout is suspected, early resuscitation and consultation with interventional radiology and vascular surgery is warranted.

Review Case Reports
A Prolonged QTc Interval Leads to the Diagnosis of Hyperthyroidism in an Adolescent Boy.
Syncope is a common cause of pediatric emergency department visits and carries a broad differential diagnosis, which includes a few rare but critical cardiac conditions. ⋯ We review the case of an adolescent boy who presented to the emergency department after a syncopal event. He was found to have a prolonged QTc interval on electrocardiogram (ECG), without personal or family history or known risk factors. He was screened for thyroid dysfunction on a second ED visit for presyncope and was subsequently diagnosed with hyperthyroidism. The patient was treated with methimazole for 2 weeks and a repeat ECG showed normalization of the QTc interval with a QTc reduction of more than 100 ms; routine thyroid studies showed correction of thyroid stimulating hormone and free thyroxine levels shortly thereafter. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case and review of the medical literature should raise awareness for the emergency physician to consider evaluation of thyroid function in pediatric patients with QT interval prolongation and vice versa, potentially averting dangerous dysrhythmias.

Fishhook injuries are an uncommon trauma, and removing a penetrating fishhook is a complicated maneuver, especially if the wound involves delicate anatomical structures like the ocular region. ⋯ Emergency physicians should be aware of all the possible approaches to fishhook penetrating injuries. If the fishhook does not involve the globe and an ophthalmologist is not available, the injury may be managed in the emergency department.

Left ventricular assist devices (LVADs) can be used as a bridging therapy for myocardial recovery or cardiac transplant, as well as a destination therapy for long-term support in patients with advanced heart failure. Patients with LVADs can present to the emergency department (ED) for acute deterioration and emergency physicians (EPs) must be equipped with the necessary knowledge and skill to treat this unique population. ⋯ Patients with LVADs have altered anatomy and physiology. Therefore, an understanding of key modifications to standard POCUS views is necessary so that EPs can use POCUS effectively in their evaluation of these patients.

Ureteral stones are a common diagnosis in the emergency department (ED) setting, often found with computed tomography (CT). The high frequency of phleboliths can confound ureteral stone diagnosis on CT imaging. ⋯ Phleboliths are a common finding on CT imaging. Radiological findings of rim sign and comet tail sign may help to differentiate phleboliths and ureteral stones; however, their low sensitivity and inconsistent presentation should prompt greater reliance on other signs of ureteral obstruction to aid in diagnosis of undifferentiated pelvic calcifications.
