Refractory ventricular fibrillation with cardiac arrest caused by occlusion of the left main coronary artery may rapidly become fatal. In this report, we describe the case of a 70-year-old male who presented to emergency department with chest pain. Electrocardiogram showed ST-segment elevation in leads aVR and aVL and ST-segment depression in leads v3, v4, v5, v6, 2, 3, and aVF. ⋯ Emergency coronary angiography showed almost total occlusion of the left main coronary artery. Percutaneous coronary intervention with a stent restored coronary perfusion. The patient was discharged on day 6 without serious sequelae or neurological deficits.

Cranial polyneuropathy is commonly caused by Lyme disease. We discuss the case of a man who presented with cranial nerve deficits causing dysphagia, dysphonia and facial weakness. ⋯ On review, this phenomenon is rarely reported, but has been observed with a number of herpes family viruses. In emergency department settings, clinical suspicion should be raised for VZV infection even in the absence of rash in patients that present with multiple cranial nerve palsies.

Cricothyrotomy may be necessary for airway management when a patient's airway cannot be maintained through standard techniques such as oral airway placement, blind insertion airway device, or endotracheal intubation. Wire-guided cricothyrotomy is one of many techniques used to perform a cricothyrotomy. Although there is some controversy over which cricothyrotomy technique is superior, there is no published data regarding long term retention rates. The purpose of this study is to determine whether ground based paramedics can be taught and are able to retain the skills necessary to successfully perform a wire-guided cricothyrotomy. ⋯ Paramedics can be taught and can retain the skills necessary to successfully perform a wire-guided cricothyrotomy on a simulator. Future research is necessary to determine if paramedics can successfully transfer these skills to real patients.

Dysnatremia is one of the most commonly encountered electrolyte disorders in the emergency department (ED). Few studies have reported the prevalence of dysnatremia in elderly patients without chronic kidney disease (CKD). We investigated the prevalence of dysnatremia in elderly patients without CKD in an emergency department in Japan. ⋯ In elderly patients, the prevalence of hyponatremia was higher in patients without CKD than in patients with CKD. Special attention should be paid to elderly patients without CKD in order to prevent severe hyponatremia.
