A 41-year-old male with PMH of uncontrolled DM was admitted for cellulitis of the left lower leg. He continued to worsen despite 5 days of outpatient therapy with clindamycin. Foot ulcer and blood cultures from hospital day 1 grew MSSA; MRI was not indicative of osteomyelitis or septic arthritis. Clindamycin was discontinued, and oxacillin 2 g every 4 h was initiated on day 5. On day 7, oxacillin was changed to ceftriaxone 2 g every 24 h for 4 weeks of outpatient therapy.
A 35-year-old female was admitted for fever with swelling and pain at the site of the peripherally inserted central catheter (PICC) in her left arm. She had a PMH of gastroparesis with multiple abdominal surgeries and was reliant on total parenteral nutrition. Blood cultures revealed MSSA, and her PICC was removed for 48 h before a new one was placed. She received ceftriaxone 1 g every 24 h on days 1–3. Ceftriaxone was switched to oxacillin 2 g every 6 h on day 4. She was changed back to ceftriaxone 2 g every 24 h on day 12, then discharged to a long-term acute care (LTAC) facility on day 23. She continued ceftriaxone at LTAC for 8 additional days.
