Considering current limitations in known treatment options and the significant disability associated with headache disorders, investigation of additional options is needed. Although occipital nerve blocks (ONBs) are currently being utilized frequently in specialty settings, the potential role of ONBs as an alternative to opioids for the management of acute headache episodes in primary and emergency care settings is not yet understood. ⋯ Interest in the use of ONBs in acute care settings is increasing. Current evidence supports that ONBs can be delivered safely in an outpatient setting by providers who have been trained in and have practiced this procedure. Although additional research is needed, current evidence supports that ONBs can be useful in treating acute headaches in an emergency care setting.

Emergency Department (ED) student-based research assistant programs have been shown to be effective in enrolling patients when the students receive university course credit or pay. However, the impact on research outcomes when university students act as volunteers in this role is relatively unknown. ⋯ Utilizing university student volunteers to facilitate research enrollment in the ED is effective and allows for the capture of a high percentage of potentially eligible patients into prospective clinical research studies.

While headache is a common emergency department chief complaint, cerebral venous sinus thrombosis (CVST) is an infrequently encountered cause of headache and is often not included in emergency physicians' differential diagnoses for headache. Our objective is to review the latest data on epidemiology, presenting symptoms, diagnosis, and treatment of CVST. ⋯ A 27-year-old female presented to our emergency department with headache, blurred vision, and vomiting a day after being diagnosed with acute otitis media. Computed tomography scan of the brain without contrast in the emergency department was suggestive of CVST. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although a rare cause of headache, CVST should be considered for a subset of patients presenting to the emergency department with the common complaint of headache. CVST is diagnosed by magnetic resonance venogram or computed tomography venogram of the brain. Anticoagulation with close monitoring in consultation with appropriate experts is a safe first-line therapy for CVST, even in patients with hemorrhage on initial imaging.

An elevated lipase typically confirms the diagnosis of pancreatitis. Elevated lipase may be associated with other disorders, typically with some influence on the pancreas. The differential is more limited than elevated amylase secondary to the mostly unique production of lipase in pancreatic acinar cells. Elevated lipase has been reported in patients with inflammatory bowel disease, but not previously reported in infectious colitis. ⋯ A 65-year-old woman presented to the emergency department with left lower quadrant abdominal pain radiating to her left flank worsening over 2 days. She denied epigastric pain. She had occasional nausea and occasional nonbilious and nonbloody emesis, and also reported diarrhea and weight loss over the preceding months. Laboratory values were largely unremarkable except for a grossly elevated lipase level. Computed tomography scan of her abdomen was performed and revealed findings consistent with infectious colitis, without signs of pancreatic inflammation or other findings associated with pancreatitis. She was admitted to the hospital and treated for infectious colitis with antibiotics and improved over 2 days, and was subsequently discharged for follow-up with her gastroenterologist. This is the first reported case of elevated lipase without pancreatitis associated with infectious colitis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be aware of other potential causes of elevated lipase and not assume that all cases of elevated lipase are associated with pancreatitis. This may possibly avoid unnecessary admission in situations that are not clearly pancreatitis.

The differential diagnosis of isolated oculomotor nerve paresis ranges from benign to potentially lethal pathologies. Intracranial tuberculosis (TB), as in the case of this patient, carries a high morbidity and mortality. Early diagnosis is crucial to improve patient outcomes. ⋯ We present the case of a 46-year-old man with a chief complaint of 5 days of diplopia. His examination was remarkable for right inferolateral exotropia and weakness of the right medial rectus. Due to the neurologic findings, we obtained a computed tomography brain scan, which revealed a ring-enhancing lesion within the central midbrain with vasogenic edema causing mass effect on the cerebral aqueduct. Further evaluation revealed tuberculosis (TB) as the underlying etiology. He was placed on steroids and a four-drug anti-TB regimen with resultant improvement of his symptoms. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Intracranial tuberculoma can present with an isolated oculomotor nerve paresis in the absence of pulmonary or systemic symptoms. This case emphasizes the importance of maintaining a broad differential when investigating isolated oculomotor nerve paresis.
