The detrimental effects of hyperoxia exposure have been well-described in patients admitted to intensive care units. However, data evaluating the effects of short-term, early hyperoxia exposure in patients intubated in the prehospital setting or emergency department (ED) have not been systematically reviewed. ⋯ There is a paucity of data that examined the effects of severe hyperoxia exposure in the acute, post-intubation phase of the prehospital and ED settings. Further research with standardized definitions is needed to provide more detailed guidance regarding early oxygen titration in intubated patients.

In response to the COVID-19 pandemic, San Francisco, California issued a shelter-in-place (SIP) order in March 2020, during which emergency physicians noted a drop in trauma cases, as well as a change in traditional mechanisms of trauma. ⋯ Understanding the changing epidemiology of TBI during the COVID-19 pandemic can aid in immediate and future disaster resource planning.

Review Case Reports
Spontaneous Pneumocephalus: A Case Report with a Literature Review.
Pneumocephalus is defined as gas in the intracranial space. Common causes include head trauma, surgery, and diagnostic/therapeutic procedures resulting from the direct disruption of the dura. Spontaneous or nontraumatic pneumocephalus is an uncommon condition, often caused by infection, either due to insidious disruption of the dura or gas-forming pathogens. ⋯ Herein, we report a rare case of spontaneous pneumocephalus associated with meningitis in a patient who received conservative treatment without surgical intervention. Blood culture revealed group A streptococcus. The pneumocephalus subsided gradually with antibiotic treatment, and no neurological deficits remained. A follow-up brain computed tomography scan showed the absence of pneumocephalus, but it showed progressive hydrocephalus. The patient was discharged on the 21st day of hospitalization. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous pneumocephalus associated with meningitis is rare. It should always raise the suspicion of meningitis and prompt suitable treatment. Emergency physicians should always be vigilant for this particular possibility on brain computed tomography.
