: A 34-year-old man with 22q11.2 deletion syndrome (DiGeorge syndrome) concurrently suffered from myopathy and eosinophilic pneumonia shortly after receiving daptomycin (DAP) for right-sided infective endocarditis. The simultaneous occurrence of these phenomena in relation to DAP therapy has not been previously well described. An allergic reaction was suspected as a possible etiology of these DAP-related complications. This case highlights the need for close observation in order to detect both m...

An 81-year-old Japanese male with primary Sjogren syndrome (pSS) developed a low-grade fever and productive cough which were refractory to antibiotic therapy. Based on the high level of eosinophils observed in his bronchial alveolar lavage, he was diagnosed with chronic eosinophilic pneumonia (CEP) and successfully treated by oral prednisolone. Interstitial lung diseases associated with pSS (pSS-ILDs) usually present as nonspecific interstitial pneumonia or usual interstitial pneumonia; therefor...

Abstract A 53-year-old man with a past medical history of total arch replacement surgery and severe aortic regurgitation presented with a 1-month history of persistent general malaise, anorexia, body weight loss and night sweats. His recent history included gingival hyperplasia for 6 years, gingivitis after tooth extraction 3 years before, prolonged inflammatory status for 4 months, fundal hemorrhage and leg tenderness for 2 months. A pathogen was detected from blood culture, but conventional mi...

A 69-year-old man with diabetes mellitus was diagnosed with a prostate abscess. Although the pathogen was fluoroquinolone-resistant Escherichia coli and the oral administration of trimethoprim-sulfamethoxazole was initiated, the infection recurred after three months. The antibiotic therapy was subsequently changed to intravenous fosfomycin, and the patient's condition promptly improved. Four weeks of fosfomycin therapy was successfully continued without any adverse events. In the era of antibiot...

A 64-year-old man suffering polyarthralgia and bone pain was referred to our hospital. Renal dysfunction, hypophosphatemia and increased levels of bone alkaline phosphatase were found. The patientʼs serum creatinine level had gradually increased after the initiation of adefovir dipivoxil administration for hepatitis B. In agreement with multifocal uptakes of bone scintigraphy, iliac bone biopsy revealed an abnormal increase in osteoid tissues. Reducing the dose of adefovir and initiating the adm...

: 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 ...

: We describe a rare case of recurrent Stenotrophomonas maltophilia bacteremia in a previously healthy 45-year-old man. The infection was caused by osteomyelitis at the site of an iliac crest bone graft harvest. A genetic analysis using enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) revealed that the blood isolates and pathogens obtained from the surgical wound were identical. Initial treatment with levofloxacin and cefozopran was ineffective, but the patien...

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...
