Varicella-zoster virus is typically encountered in the emergency department (ED) in two forms: varicella (chickenpox) in children and zoster (shingles) in older adults. Zoster is infrequently encountered in young, healthy adults, and neurological complications are extremely rare. ⋯ We describe a case of a previously healthy 36-year-old woman who presented to the ED with fever, nuchal rigidity, and headache 4 days after being diagnosed with herpes zoster and started on oral valacyclovir. Lumbar puncture confirmed herpes zoster meningitis. Despite initiation of antivirals within 48 h of symptom onset, progression to zoster meningitis occurred. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians must be aware that neurological complications of varicella zoster can develop despite initiation of oral antivirals. These patients must be identified in the ED, as admission for intravenous antivirals is indicated.

Prolonged emergency department (ED) wait times could potentially lead to increased morbidity and mortality. While previous work has demonstrated disparities in wait times associated with race, information about the relationship between experiencing homelessness and ED wait times is lacking. ⋯ Undomiciled patients experience longer ED wait times when compared with domiciled patients. This disparity is not explained by undomiciled patients seeking care in the ED for minor illness, because the disparity is more pronounced for urgent and emergent triage categories.

Central venous catheter (CVC) placement is commonly performed in the emergency department (ED), but traditional confirmation of placement includes chest radiograph. ⋯ POCUS can rapidly and reliably confirm CVC placement, as well as evaluate for postprocedural complications. Knowledge of this technique can assist emergency clinicians.

Acetazolamide is contraindicated in patients undergoing dialysis and should be used with caution in patients with chronic kidney disease (CKD). Here, we evaluate the effect of the concomitant use of aspirin by patient with CKD using acetazolamide. ⋯ A 63-year-old man with CKD and multimorbidity presented at our Emergency Department (ED) with general weakness and dyspnea for 4 days. Work-up at the ED revealed severe metabolic acidosis and hyperammonemia, which were initially considered signs of sepsis due to an elevated C-reactive protein level and pyuria. However, subsequent blood work indicated hyperchloremic acidosis with low lactate levels. After reviewing his medical history, we suspected the concomitant use of acetazolamide and aspirin as the etiology. Weakness, acidosis, and hyperammonemia were resolved after the patient discontinued acetazolamide. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Severe acidosis can be life threatening. Acetazolamide is known for causing mild metabolic acidosis, except in patients with severely impaired renal function. Here, we present a patient with mildly impaired renal function and concomitant aspirin use who developed severe metabolic acidosis and hyperammonemia after being prescribed acetazolamide. Regardless of the severity of the disease, patients with CKD should avoid taking acetazolamide concomitantly with aspirin.
