A 35-year-old female with PMH of invasive breast carcinoma with reported tenderness around her chemotherapy port for 1 week was admitted for Gram-positive BSI. The chemotherapy port was removed on day 2 and cultured MSSA. Vancomycin was discontinued in favor of oxacillin 2 g every 4 h until day 5, when oxacillin was discontinued, and she was discharged on 2 weeks of ceftriaxone 2 g every 24 h.
A 55-year-old male was admitted with severe pain secondary to a fall with a PMH for HTN and advanced alcoholic cirrhosis. Blood cultures on day 1 were positive for MSSA. Oxacillin 2 g every 4 h was given on days 3–12. The patient achieved MC but failed to achieve CC (WBCs did not normalize within 7 days). On discharge (day 12), he was switched from oxacillin to ceftriaxone 2 g every 24 h. The patient died from liver disease complications 7 days after discharge.
