Billions of travelers pass through airports around the world every year. Airports are a relatively common location for sudden cardiac arrest when compared with other public venues. An increased incidence of cardiac arrest in airports may be due to the large volume of movement, the stress of travel, or adverse effects related to the physiological environment of airplanes. ⋯ Large numbers of people, a high density of public-access AEDs, and on-site emergency medical services (EMS) resources are probably the major reasons why cardiac arrest outcomes are so favorable at airports. The success of the chain of survival found at airports may imply that applying similar practices to other public venues will translate to improvements in cardiac arrest survival. Airports might, therefore, be one model of cardiac arrest preparedness that other public areas should emulate.

Lithium is considered a mood stabilizer for bipolar affective disorders, but it has a narrow therapeutic index of 0.6-1.2 mEq/L. This can easily result in toxic levels after minimal changes in renal function or individual patient's pharmacokinetics. Lithium toxicity can arise with levels as low as 1.5 mEq, and there are limited therapeutic options to treat these patients presenting to the emergency department (ED). ⋯ However, SPS has been associated with intestinal necrosis and may cause treatment limiting hypokalemia, and is therefore not commonly recommended in treatment algorithms for lithium toxicity. A newer cation exchange resin, sodium zirconium cyclosilicate (SZC), may provide a safer alternative to SPS while also aiding in the clearance of lithium. We present a patient case where a patient with symptomatic acute-on-chronic lithium toxicity had increased clearance of lithium after a dose of SZC.

Abdominal pain is a common presenting complaint to the Emergency Department (ED). Often, rare etiologies can be discovered in the work up of this common complaint. Here we present the case of an adolescent female who presented with abdominal pain and was found to have obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) or Herlyn-Werner-Wunderlich Syndrome. ⋯ MRI can also be useful to further delineate specific anatomy. It is important for the emergency physician to be aware of this entity as most patients don't present to care until acute, severe symptoms develop. This makes it more likely for them to seek care in the ED as opposed to the outpatient setting.
