A Rare Case of Spontaneous Pseudo-Aneurysm Rupture of an Extra-Anatomical Axillo-Femoral Bypass Graft: A Case Report.
Sudden onset of chest wall bulging is a rare chief symptom in the emergency department (ED). However, it may represent life-threatening diseases, such as tumor bleeding, aneurysm rupture, or subcutaneous emphysema. ⋯ We present an 89-year-old woman who visited our ED with a chief symptom of abrupt bulging of the right chest wall accompanied with severe pain. The patient had a history of peripheral artery disease and 10-year post-extra-anatomical axillo-femoral bypass (AxFB) status. After several examinations, the patient was diagnosed as having spontaneous pseudo-aneurysm rupture of an extra-anatomical AxFB graft. Emergency endovascular intervention with stent insertion was performed immediately, and the patient was eventually discharged successfully. WHY SHOULD EMERGENCY PHYSICIANS BE AWARE OF THIS?: Although spontaneous pseudo-aneurysm rupture of an extra-anatomical AxFB graft is rare, the disease may consequently lead to a fatal outcome once misdiagnosed, and prompt intervention is warranted. Therefore, we should always consider the differential diagnosis of this disease in patients with a bulging chest wall and history of AxFB graft placement.

Ultrasound (US) is the preferred method of initial evaluation for appendicitis in pediatrics. However, limited accuracy of US for appendicitis is an obstacle to implementation of US-first protocols at facilities less experienced with US. ⋯ An US-first imaging protocol for appendicitis in children shows chronologic improvement in diagnostic accuracy. This may provide encouragement to facilities using computed tomography-based diagnostic protocols to implement US-first protocols to reduce childhood radiation exposure.

Intracardiac foreign bodies have been described in the literature, however, they are rare entities, particularly in pediatric patients. We present a case of a teenage boy diagnosed with perimyocarditis who was found to have an unexpected underlying etiology: an unknowingly swallowed sewing pin. ⋯ A 17-year-old boy presented to the Emergency Department with 3 days of chest pain suggestive of perimyocarditis, in the absence of prodromal symptoms or trauma. Electrocardiogram at the time of presentation demonstrated diffuse ST-segment elevation consistent with perimyocarditis. A chest radiograph was significant for a linear density in the anterior mid chest, concerning for foreign body. Chest computed tomography confirmed the presence of a 3.5-cm linear metallic foreign body within the right ventricle. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case demonstrates the need to consider alternative etiologies for perimyocarditis, especially in the absence of the typical prodromal symptoms. In addition, it highlights the potential devastating complications of foreign body ingestion and challenges the paradigm that ingested sharp linear foreign bodies < 5 cm in length rarely cause problems.

In the prehospital setting, the use of ambulance lights and sirens (L&S) has been found to result in minor decreases in transport times, but has not been studied in interfacility transportation. ⋯ The use of L&S during interfacility critical care transport was associated with a statistically significant time reduction in this urban, single-system retrospective analysis. Although the use of L&S was not associated with rush-hour transports, the greatest time reduction was associated with L&S transport during these hours.

Immune checkpoint inhibitors (ICIs) have a wide range of toxicities affecting potentially any organ system stemming from increased activity within the T-cell lineage similar to that observed in autoimmunity. ⋯ A 57-year-old man with metastatic papillary renal cell carcinoma treatment with combination ICI therapy presented with a history of rapidly progressive diplopia. Neurological examination revealed bilateral fatigable ptosis and asymmetrical ophthalmoplegia. His clinical findings were in keeping with an immune-mediated myasthenia gravis. He was immediately commenced on 1 mg/kg of intravenous methylprednisolone and pyridostigmine 60 mg 3 times a day. On day 2 of admission he was given 1 g/kg of intravenous immunoglobulins. He made a rapid and full clinical recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Immune-mediated myasthenia gravis is an important toxicity of ICIs. Early recognition and treatment of this presentation may reduce the significant morbidity and mortality associated with it.
