Aortic dissection (AD) is a challenging diagnosis associated with severe mortality. However, acute AD is a rare clinical entity and can be overevaluated in the emergency department. D-dimer, both alone and in combination with the Aortic Dissection Detection Risk Score (ADD-RS), has been studied as a tool to evaluate for AD. ⋯ Neither D-dimer nor the ADD-RS alone provides adequate sensitivity to exclude acute AD. However, a negative D-dimer combined with an ADD-RS < 1 is likely sufficient to rule out AD. Even with these findings, physicians must place clinical judgment above laboratory testing or scoring systems when deciding whether to pursue a diagnosis of acute AD.

Background Hair-thread tourniquet syndrome (HTTS) is the constriction of an appendage or tissue by a hair thread, which can cause ischemia and necrosis of distal tissues. Depilatory agents have the potential to release the hair tourniquet without exposing the patient to the risks of surgery.

Seizures: A Rare Presentation of Autonomic Dysreflexia in a Young Adult with Complete Spinal Cord Injury.
Autonomic dysreflexia (AD) is a common complication for individuals with cervical or upper-mid thoracic spinal cord injury (SCI). It is a life-threatening emergency; however, it is rarely encountered by many emergency physicians, thus, ongoing awareness of the topic is necessary. ⋯ An 18-year-old man with cervical spinal cord injury presented to the Emergency Department with headache, nausea, elevated blood pressure, and seizures. He was treated with antiepileptics and transferred to the pediatric intensive care unit (PICU). The PICU care team recognized AD as the cause of the seizure, secondary to a clogged suprapubic catheter causing overdistension of his bladder. Once replaced, over 1 liter of urine drained from his bladder and his autonomic symptoms resolved. He became hypotensive and required fluid resuscitation, but no further seizures occurred. Why Should an Emergency Physician Be Aware of This? Although rare, AD can result in seizures, intracerebral hemorrhage, or even death if not recognized or treated appropriately. Emergency physicians should recognize headaches, facial flushing, and sweating as early symptoms of AD, along with acute elevation in blood pressure (noting that baseline blood pressure may be lower in individuals with SCI). Management involves evaluating and treating noxious stimuli below the level of neurologic injury. Symptom management alone, without resolution of the underlying issue, can add to morbidity and mortality.
