Coronavirus disease 2019 (COVID-19) is a disruptive pandemic that has continued to test the limits of health care system capacities. It is important to highlight the specific challenges facing US neurosurgery during these difficult circumstances. In the present study, we have described our neurosurgery department's unique experience during the COVID-19 pandemic. ⋯ By detailing our experience during the COVID-19 pandemic, we hope to have provided a detailed picture of the challenges facing neurosurgery within an academic medical center.

The appearance of the novel severe acute respiratory syndrome-coronavirus-2 (SARS-CoV‑2) poses challenges in ophthalmology particularly for eye banks. A valid risk assessment for the removal and processing of donor corneas is difficult due to the lack of data. The risk to infect transplant recipients with SARS-CoV‑2 still appears very unlikely due to the experience with severe acute respiratory syndrome -coronavirus(‑1) (SARS-CoV(‑1)) and Middle East respiratory syndrome-coronavirus (MERS-CoV); however, due to the occurrence of angiotensin-converting enzyme 2 (ACE2) receptors in the cornea an infection of this tissue with SARS-CoV‑2 cannot be completely excluded. Therefore, routine testing of the organ culture medium used for donor corneas for SARS-CoV‑2 prior to transplantation during the coronavirus disease 2019 (COVID‑19) pandemic should be considered.

To analyse the high-resolution computed tomography (HRCT) early imaging features and the changing trend of coronavirus disease 2019 (COVID-19) pneumonia. ⋯ The typical early CT features of COVID-19 pneumonia are ground-glass opacity, and located peripheral or subpleural location, and with supply pulmonary artery dilation. Reticulation was evident after the 2nd week and persisted in half of patients evaluated in 4 weeks after the onset. Long-term follow-up is required to determine whether the reticulation represents irreversible fibrosis.
