Corticosteroids and other immunosuppressants for immune-related adverse events and checkpoint inhibitor effectiveness in melanoma.

Background: Recent studies indicate an association between immunosuppression for immune-related adverse events (irAEs) and impaired survival in patients who received immune checkpoint inhibitors. Whether this is related to corticosteroids or second-line immunosuppressants is unknown. In the largest cohort thus far, we assessed the association of immunosuppressant type and dose with survival in melanoma patients with irAEs.

After insertion of a nasal oxygen catheter, a 65-year-old man developed severe subcutaneous emphysema of the face and neck. The catheter damaged the mucosa of the left inferior nasal concha. Oxygen was blown into the subcutis.
