Pneumocephalus has been described as an unintended outcome after epidural injections. However, oculomotor palsy from pneumocephalus after epidural injection is very rare. ⋯ We report a case of pneumocephalus-induced sixth nerve palsies and diplopia in an 87-year-old woman after epidural steroid injection. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Pneumocephalus-induced oculomotor palsy is a rare complication after epidural injection, a commonly performed medical procedure. Knowledge of this presentation will help emergency physicians distinguish between this entity and other causes of neurologic deficits.

Diagnosis of acute poisoning in patients with altered mental status and absent history is a challenging diagnostic problem in clinical practice. ⋯ A prediction model with a derived risk score was developed with a high negative predictive value and may have potential in assessing risk of poisoning in altered mental status and may have value in a prehospital environment or at triage.

The assessment of capillary refill time (CRT) is a common physical examination technique. However, despite its importance and its widespread use, there is little standardization, which can lead to inaccurate assessments. ⋯ Results indicate that some physicians gave, on average, slower CRT estimates, whereas others gave, on average, faster CRT estimates. Objective approaches and innovations in assessment of capillary refill have the potential to increase the diagnostic accuracy of this important clinical examination finding.

Methylene blue is the first-line therapy for methemoglobinemia, but it can be intermittently unavailable due to production issues. For this clinical scenario, alternative treatment options need to be explored. Hyperbaric oxygenation (HBO) is conventionally applied as an adjunctive therapy during the systemic administration of methylene blue. Currently, little is known regarding the effects of HBO monotherapy in methemoglobinemia. We report a case of methemoglobinemia that was successfully treated with HBO monotherapy. ⋯ A 41-year-old man presented to the Emergency Department with dyspnea and dizziness subsequent to smoking in a garage filled with motor vehicle exhaust gas. There were no abnormal heart or lung sounds. While administering oxygen flowing at 15 L/min via a mask with a reservoir bag, blood tests revealed high methemoglobin (MetHb) levels at 59.6%. He was treated with HBO monotherapy, and sequential tests showed that the MetHb level decreased significantly to 34.0%, 12.8%, 6.2%, and eventually, 3.5%. He was discharged with stable vital signs the next day. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: HBO monotherapy is an effective alternative treatment for methemoglobinemia when methylene blue is not available.
