Cranial Nerve Six Palsy After Vaginal Delivery with Epidural Anesthesia: A Case Report.
This case report describes a 34-year-old woman who developed diplopia and strabismus 2 weeks after a vaginal delivery and epidural anesthesia. ⋯ A 34-year-old women presented to the emergency department (ED) with continued headache and new-onset diplopia after having undergone epidural anesthesia for a vaginal delivery 2 weeks prior. During that time, she underwent two blood patches, rested supine, drank additional fluids, and consumed caffeinated products for her spinal headache. When she developed double vision from a cranial nerve VI palsy, she returned to the ED. At that time, she had a third blood patch performed, and she was evaluated by a neurologist. The medical team felt the cranial nerve VI palsy was due to the downward pull of the brain and stretching of the nerve. Magnetic resonance imaging and neurosurgical closure of the dura were considered as the next steps in treatment; however, they were not performed after being declined by the patient. All symptoms were resolved over the next 3 weeks. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case illustrates the uncommon complication of a cranial nerve VI palsy from a persistent cerebrospinal fluid leak after a dural puncture. Emergency physicians must be aware that diplopia can be a rare presenting symptom after patients undergo a lumbar puncture. Furthermore, emergency physicians should be aware of the multiple treatment options available. Knowledge of the timeline of resolution of the diplopia is necessary to make shared decisions with our patients about escalating care.

Page kidney is a rare condition in which an external compression of the kidney as a result of a hematoma or mass causes renal ischemia and hypertension. In a patient with flank pain, elevated blood pressure, and recent trauma, this condition should be considered. Since this condition was first described in 1939, more than 100 case reports have surfaced. ⋯ We describe the case of a 26-year-old man who presented to the Emergency Department with flank pain, vomiting, and elevated blood pressure. A computed tomography scan of the abdomen and pelvis confirmed the presence of a perinephric hematoma, and the interventional radiology team was consulted to resolve the Page kidney. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Symptoms seen in Page kidney may be similar to other more common diagnoses encountered in the emergency department. It is important to maintain a high suspicion and order imaging studies as needed, especially in the setting of trauma, or a recent procedure in the vicinity of the renal parenchyma.

A cervical radiofrequency ablation is a procedure that can be performed to treat arthritis-related pain in the neck and upper back. There have been no large studies reporting complications after this procedure. We report a case of a 55-year-old woman with iatrogenic vertebral artery dissection of C3-C4 with segmental occlusion leading to a posterior fossa stroke and lateral medullary stroke after a high-grade cervical nerve ablation. ⋯ A 55-year-old woman presented to the Emergency Department with vomiting, neck pain, temperature changes, dizziness, and dysarthria after undergoing C2-C3, C4-C5 nerve ablation 30 min prior to arrival. The patient was found to have a vertebral artery dissection with posterior fossa and lateral medullary stroke. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Vertebral artery dissection and subsequent stroke should be considered with recent cervical facet joint injections, such as intra-articular facet joint injections, medial branch blocks, or medial branch radiofrequency nerve ablation. The case we report shows devastating outcomes that can result from what many consider a relatively simple procedure.

Although common in pediatric airway equipment, positive-pressure relief ("pop-off") valves are also present on some adult resuscitator bags. These valves are designed to decrease barotrauma but, in doing so, limit the airway pressure provided during manual bag-assisted ventilation. In critically ill adult patients with high airway pressures, these valves can be detrimental and result in hypoventilation and subsequent hypoxemia. ⋯ In the 7 days after an unannounced introduction of new resuscitator bags with pop-off valves in the emergency department, there were 3 adult patients for whom an open pop-off valve resulted in hypoventilation and hypoxemia. These cases involved both medical and traumatic pathologies. In each case, there was a delay in discovering the change to a resuscitator bag equipped with a pop-off valve. Once the emergency physicians noticed the pop-off valve and closed them, there was significant improvement in ventilation and oxygenation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Hand-operated resuscitator bags are an essential tool for airway management. These cases represent two main lessons: changing airway equipment without notifying staff is dangerous, and an open pop-off valve will result in inadequate ventilation when patients have high airway pressures, without the tactile feedback of difficult bagging. Emergency physicians should be aware of equipment changes and know to disable the pop-off valve on resuscitator bags if they find them in their departments.

Case Reports
Spontaneous Cerebrospinal Fluid Leak in a Patient with Asymptomatic Idiopathic Intracranial Hypertension.
Spontaneous cerebrospinal fluid (CSF) leaks occur when there is a tear in the dura mater. Spontaneous CSF leaks are rare, and often associated with conditions like intracranial hypertension, connective tissue disorders, or congenital defects in the dura mater. ⋯ The patient was a 66-year-old woman who presented to the Emergency Department with clear, positional nasal discharge from her left nostril for 1 week. She had a history of chronic headaches, which seemed to have been relieved around the time of onset of her rhinorrhea. Diagnostic imaging, including computed tomography and magnetic resonance imaging scans, confirmed the presence of a CSF leak and a left temporal meningoencephalocele. The patient subsequently underwent surgical repair of the leak and ventriculoperitoneal shunt placement, and was discharged home in stable condition. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Early detection of CSF leaks require a thorough history and physical examination, and is crucial in preventing potentially life-threatening complications such as meningitis and intracranial abscesses.
