RESUMEN
We herein report a case of persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia that was successfully treated with combination therapy consisting of high-dose daptomycin (DAP, 10 mg/kg) and rifampicin. The patient's condition was complicated with multiple infectious foci, including an iliopsoas abscess and epidural abscess, as well as discitis and spondylitis at the cervical, thoracic and lumbar levels. Monotherapy treatments with vancomycin, linezolid and usual-dose DAP were all ineffective. It has been shown that usual-dose DAP administration may result in the emergence of a resistant strain and treatment failure. We would like to emphasize the importance of high-dose DAP therapy for MRSA bacteremia, a condition with a potentially high mortality rate.

We herein describe a case of Wuchereria bancrofti infection in a previously healthy 37-year-old Nepalese man. The patient presented with a history of milky urine with subsequent acute urinary retention lasting for a few days. The presence of microfilariae was confirmed on both peripheral blood and urine smears obtained at midnight. He was conservatively treated with diethylcarbamazine combined with doxycycline. Filariasis was previously endemic in southern parts of Japan, although it has been eradicated. Clinicians should remember filariasis as a potential etiology of urinary retention, especially in cases that may be associated with imported infectious disease.
