Q. A 48-year-old woman presents to her physician’s office for painful oral ulcers for the past month. She has a history of acute myeloid leukemia (AML) that was treated with allogeneic hematopoietic stem cell transplantation (HSCT) and cyclosporine therapy. Her temperature is 98.4°F (36.8°C), heart rate is 90/min, respiratory rate is 14/minute, and blood pressure is 110/70 mm of Hg. Physical examination shows severe dry oral mucosa. A few white ulcers on the buccal mucosa and tongue, covered with whitish membranes are noted. The rest of the examination is normal. What is the next appropriate step in this patient’s management?
