Carotid blowout syndrome (CBS) is an uncommon but potentially life-threatening condition characterized by the spontaneous or traumatic rupture of the carotid artery in the neck. Oftentimes, CBS is due a loss of structural arterial integrity from local radiotherapy or surgical procedures. A vast majority of patients who develop CBS also have a previous diagnosis of head and neck cancer. ⋯ Proper wound packing and an ultrasound of the neck for a proper diagnosis may have prevented the need for surgical intervention in this case. Although CBS is not common, complications can lead to death as seen in this case. Timely recognition and proper interventions are critical for preventing potentially fatal outcomes in those with CBS.

Naphazoline, a nonspecific alpha-adrenoceptor stimulant, is a potent vasoconstrictor used in nasal sprays, eye drops, and over-the-counter antiseptics. Naphazoline intoxication increases afterload by constricting the peripheral arteries, which can lead to complications including multiple organ failure. Although phentolamine, a nonselective alpha-adrenoceptor antagonist, and nicardipine, a calcium channel blocker, are used for the treatment of naphazoline intoxication, no established administration protocols currently exist. ⋯ At 10 h after treatment initiation, the nicardipine dose peaked at 9 mg/h (1.9 μg/kg/min). Treatment was discontinued 8 h later, and the patient was discharged on the fourth day without sequelae. In conclusion, the use of a minimally invasive cardiac output monitoring system to track vascular resistance can effectively guide the dosing of phentolamine or nicardipine in the treatment of naphazoline intoxication.

Case Reports
Tattoo-induced allergic contact dermatitis presents diagnostic challenge as a cellulitis mimic.
Allergic contact dermatitis (ACD) is a prevalent condition associated with numerous potential allergen exposures. Tattoo ink is variable and may contain allergens that can be overlooked in patient education and diagnosis. We present a 27-year-old female with ACD following a new tattoo. ⋯ Consequently, the appropriate care was delayed by a month, resulting in significant morbidity. This case demonstrates the potential for ACD to present similarly to cellulitis in an ED setting and the need for clinical vigilance in diagnosis of ACD. It also highlights the importance of detailed patient education on potential allergen sources particularly in the context of tattooing, which is performed with unregulated and variable ink products.

Spontaneous Coronary Artery Dissection (SCAD) is a significant cause of acute coronary syndrome. SCAD frequently affects young women, often without cardiovascular risk factors. ⋯ Based on clinical context, treatment is divided into conservative methods and revascularization with either percutaneous coronary intervention or bypass grafting. This case report describes a 26-year-old female with a preceding diagnosis of myopericarditis who presented to the ED with inferior STEMI and was subsequently diagnosed with a spontaneous right coronary artery dissection.
