Case Reports
Top of Basilar Syndrome Presenting With Hyperekplexia Initially Diagnosed as a Convulsive Status Epilepticus.
Hyperekplexia is a rare neurologic disorder characterized by pronounced startle responses to tactile or acoustic stimuli and increase tone. Acquired hyperekplexia is usually seen in brainstem pathologies and when it develops acutely it can be easily misdiagnosed as a convulsive seizure. ⋯ A 38-year-old man presented with acute onset generalized brief involuntary jerky movements and a decreased level of consciousness. He was initially diagnosed with convulsive status epilepticus for which he received multiple antiseizure medications without any improvement. Further investigations revealed abnormal oculocephalic reflex response and that his movements were in fact hyperkeplexia caused by brainstem infarction with basilar artery thrombus secondary to right vertebral artery dissection. Emergent thrombectomy was performed and he was eventually discharged to a rehabilitation facility. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be aware of hyperekplexia and how to differentiate it from convulsive stats epilepticus because the pathology and the emergent treatment of these 2 serious conditions are different. An underlying acquired brainstem pathology (especially basilar artery thromboembolism) should be suspected in any patient with untypical convulsive like movements along with focal neurologic signs compatible with brain stem pathology even when computed tomography imaging is normal. © 2020 Elsevier Inc.

Eighty-eight percent of pediatric emergency department (ED) visits occur in general EDs. Exposure to critically ill children during emergency medicine (EM) training has not been well described. ⋯ Pediatric critical care exposure during EM training is very limited. These findings underscore the importance of monitoring trainees' case experience to inform program-specific curricula and to develop strategies to increase exposure and resident entrustment, as well as further research in this area.

Review Case Reports
Argyria, an Unexpected Case of Skin Discoloration From Colloidal Silver Salt Ingestion.
Argyria is a rare condition characterized by gray/blue dislocation of the skin caused by chronic exposure to silver salts. ⋯ We review the case of an 81-year-old man who presented to the emergency department after a motor vehicle accident, was incidentally found to have skin discoloration, and was ultimately diagnosed with argyria. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although most emergency physicians will not complete a toxicology fellowship, all emergency physicians are on the front line of toxicological presentations and should be able to recognize argyria and differentiate this condition from other causes of skin discoloration.

Kounis syndrome is a rare condition that is characterized by the coexistence of acute coronary syndrome and allergic reactions; however, its time course remains unclear. We report a case of anaphylactic shock with subsequent development of ST-segment elevation myocardial infarction. ⋯ A 47-year-old man with food allergies presented to the emergency department of our hospital with breathing difficulties after eating bread. He had a history of angina and underwent stent implantation 3 years earlier. On examination, he was lethargic, disoriented, and in shock. He had a rash on his face and anterior chest wall, as well as severe itching and sweating. Anaphylaxis was diagnosed and, 3 min after presentation, 0.5 mg epinephrine was injected intramuscularly into the right thigh. Electrocardiography, which was recorded 2 min after the administration of epinephrine, was normal; however, chest pain developed suddenly 18 min later. Repeat electrocardiography showed ST-segment elevations, and emergency coronary angiography revealed total occlusion of the left anterior descending coronary artery (i.e., the previous stenting site). Recanalization of the left anterior descending coronary artery was achieved after repeated thrombus aspiration with difficulty, followed by stent implantation inside of the stent under the support of intra-aortic balloon pumping. The clinical course was uneventful. He was discharged and advised to avoid eating wheat and carry an epinephrine self-injection kit for anaphylaxis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The present case highlights the importance of recognizing Kounis syndrome in the management of anaphylactic shock because treatment may be difficult, particularly in patients with type III Kounis syndrome.

McKesson's InterQual criteria are widely used in hospitals to determine if patients should be classified as observation or inpatient status, but the accuracy of the criteria is unknown. ⋯ In older adults with syncope, those who met InterQual criteria for inpatient status had longer LOS compared with those who did not; however, the accuracy of the criteria to predict length of stay over 2 days is poor, with a sensitivity of 60% and a specificity of 48%. Future research should identify criteria to improve LOS prediction.
