Hypertensive urgency is a clinical scenario that may be associated with herbal supplement use and that requires special consideration with regard to emergency department management. ⋯ A 49-year-old man presented to the emergency department with palpitations and severely elevated blood pressure without evidence of end organ dysfunction. Hypertension failed to be controlled with multiple doses of oral clonidine and intravenous labetalol. The patient later admitted to using an herbal supplement containing yohimbine, a selective ⍺2-adrenoreceptor antagonist specifically linked to cases of refractory hypertension. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Between 17-35% of the U.S. adult population may use herbal supplements on a sporadic or regular basis; pharmacologically active agents in herbal supplements may affect both a patient's presentation and response to treatment. Most patients do not mention over-the-counter and herbal products in their medication profile unless specifically asked, and therefore it is important for emergency physicians to be aware of the pharmacologic effects of herbal supplements in the evaluation and treatment of refractory severe hypertension.

Most pediatric patients with lymphoma do not have classic symptoms of fever, night sweats, and weight loss. Lymphoma can present as vague symptoms and may mimic common pediatric abdominal emergencies. In this case report, we present a child who presented with abdominal pain and who was initially misdiagnosed as having a surgical emergency. ⋯ An 11-year-old previously healthy male was referred to the pediatric emergency department after he presented to an outside hospital with 3 days of right lower quadrant pain and 1 episode of diarrhea. The initial concern was appendicitis. He had a computed tomography scan of the abdomen and pelvis that showed thickening of the bowel wall, peritoneal thickening, and a right pleural effusion. His laboratory assessments were only notable for a mildly elevated lactate dehydrogenase level of 506 units/L. He had a colonoscopy, and biopsy specimens obtained from the terminal ileum and cecum were negative. He developed worsening symptoms, and subsequently underwent laparoscopic biopsy procedures of the omentum and terminal ileum, which were consistent with Burkitt lymphoma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We discuss the important oncologic findings of pediatric lymphoma, including oncologic emergencies and important laboratory and imaging tests that providers should consider while in the emergency department. This case highlights how pediatric lymphoma can mimic common pediatric pathologies providers often encounter in the emergency department.

Vagally mediated atrioventricular block (AVB) may occur as a result of increased parasympathetic tone. This particular AVB is infrequently described in the literature, but its prevalence may be underestimated, as it may occur without recognition. ⋯ We present a case of vagally mediated AVB that was identified by serial electrocardiography of a patient who presented to the emergency department with vomiting. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Vagally mediated AVB must be differentiated from paroxysmal, bradycardia-dependent AVB, which may progress to persistent AVB and require pacemaker placement. In an asymptomatic patient with vagally mediated AVB, pacemaker placement is contraindicated. However, if symptoms are clearly attributable to vagally mediated AVB, pacemaker placement may be reasonable.

Acute ischemic stroke (AIS) in pediatric populations accounts for more than half of pediatric strokes and is associated with significant morbidity and mortality. Pediatric AIS can present with nonspecific symptoms or symptoms that mimic alternate pathology. ⋯ A 4-month-old female presented to the emergency department for fever, decreased oral intake, and "limp" appearance after antibiotic administration. She was febrile, tachypneic, and hypoxic. Her skin was mottled with 3-s capillary refill, her anterior fontanelle was tense, and she had mute Babinski reflex bilaterally but was moving all extremities. The patient was hyponatremic, thrombocytopenic, and tested positive for influenza A. A computed tomography scan of the brain revealed an acute infarction involving the right frontal, parietal, temporal, and occipital lobes in addition to hyperdensities concerning for thrombosed cortical veins. The patient was transferred for specialty evaluation and was discharged 2 weeks later on levetiracetam. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Pediatric AIS can present with nonspecific symptoms that mimic alternate pathology. A high level of suspicion is needed so as not to miss the diagnosis of pediatric AIS in the emergency department. A thorough neurologic assessment is warranted, and subtle abnormalities should be investigated further.
