Febrile urinary tract infections (UTIs) include a spectrum of pathologies from uncomplicated pyelonephritis to urosepsis, including xanthogranulomatous pyelonephritis (XGP). Most febrile UTIs are treated with antibiotics alone, but studies indicate nearly 12% of cases of presumed simple pyelonephritis require emergent urologic intervention. How to identify these individuals, while limiting unnecessary advanced imaging and delays in diagnosis, challenges all emergency providers. We review the diagnosis and management of XGP, as well as the evidence regarding the role of renal ultrasound in the identification of complicated presentations of febrile UTIs. ⋯ We present a case of XGP, a complicated febrile UTI requiring immediate urologic intervention, diagnosed by point-of-care ultrasound. A 40-year-old female presented in severe sepsis and complaining of flank pain. Prompt bedside ultrasound demonstrated hydronephrosis, expediting definitive urologic treatment via percutaneous nephrostomy tube placement. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: With a mortality rate exceeding 40%, obstructed pyonephrosis requires prompt decompression. Given its exceptional sensitivity for identifying hydronephrosis and ability to detect abscesses and emphysematous changes, we advocate a point-of-care ultrasound-first approach to screen for cases of complicated febrile UTIs in order to expedite treatment and limit radiation in uncomplicated presentations.

Kawasaki disease (KD) is a multisystem vasculitic disease. Coronary artery aneurysms (CAAs) are the most important and life-threatening complication of KD. Various neurologic complications have been described to occur in 1-30% of patients with KD, but peripheral facial nerve palsy (FNP) is rare (0.9%). ⋯ We describe a 5-month-old male infant who presented to us with unilateral left infranuclear FNP in the convalescent phase (day 18 of illness) of incomplete KD. The initial diagnosis was not made during the first 10 days of illness (therapeutic window for immunoglobulin treatment) as he was suspected to have hand-mouth-foot disease. We believe that both the delay in diagnosis and treatment of an atypical presentation of KD, combined with the more severe vasculitis and inflammatory burden reported in these cases, contributed to the development of CAA in our patient. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the importance of considering KD diagnosis in children with prolonged unexplained fever, even with incomplete diagnostic features, as well as the need to be aware of unusual manifestations, such as FNP. Atypical cases like this may be at increased risk of CAA because of delayed diagnosis and a higher inflammatory burden; therefore, a more aggressive treatment approach may be necessary.

Emergency department (ED) treatment of hyperkalemia often involves shifting potassium into the intracellular space. There is uncertainty whether transcellular shifting causes insufficient potassium removal during hemodialysis, resulting in a subsequent need for further medical therapy or multiple sessions of hemodialysis. ⋯ Administration of transcellular shifting medications for hyperkalemia in the ED was not associated with either recurrent hyperkalemia after hemodialysis or the need for a second dialysis session within 24 h. Our findings address the uncertainty regarding transcellular potassium shifting before emergent dialysis and support safe ED administration of medications that shift potassium to the intracellular space.

A significant increase in false positive ST-elevation myocardial infarction (STEMI) electrocardiogram interpretations was noted after replacement of all of the City of San Diego's 110 monitor-defibrillator units with a new brand. These concerns were brought to the manufacturer and a revised interpretive algorithm was implemented. ⋯ This study shows that introducing a revised 12-lead interpretive algorithm resulted in a significant reduction in the number of false positive STEMI electrocardiogram interpretations in a large urban emergency medical services system. Rigorous testing and standardization of new interpretative software is recommended before introduction into a clinical setting to prevent issues resulting from inappropriate cardiac catheterization laboratory activations.

Mental health conditions account for 52.8 million (4.9-6.3%) emergency department (ED) visits in the United States. Psychotic conditions are responsible for approximately 10% of all mental health presentations. ⋯ UMC is a common etiology in patients presenting to the ED with a first episode of psychotic symptoms.
