We present two cases of imported Zika fever to Japan, in travellers returning from French Polynesia, where an outbreak due to Zika virus (ZIKV) is ongoing since week 41 of 2013. This report serves to raise awareness among healthcare professionals, that the differential diagnosis of febrile and subfebrile patients with rash should include ZIKV infection,(More)
After 70 years with no confirmed autochthonous cases of dengue fever in Japan, 19 cases were reported during August-September 2014. Dengue virus serotype 1 was detected in 18 patients. Phylogenetic analysis of the envelope protein genome sequence from 3 patients revealed 100% identity with the strain from the first patient (2014) in Japan.
We report a case of multidrug-resistant (MDR) Acinetobactor baumannii isolates obtained from a traveler returned from Brunei. Whole-genome sequencing analysis revealed that the isolates harbored blaOxA-23 and armA. The minimum inhibitory concentrations of antibiotics against the strain were as follows: imipenem, 32 μg/ml; meropenem, 32 μg/ml; ciprofloxacin,(More)
BACKGROUND Patients with acute myeloid leukemia who are treated with conventional chemotherapy still have a substantial risk of relapse; the prognostic factors and optimal treatments after relapse have not been fully established. We, therefore, retrospectively analyzed data from patients with acute myeloid leukemia who had achieved first complete remission(More)
In July 2014, a Japanese traveller returning from Thailand was investigated for fever, headache, rash and conjunctivitis. Zika virus RNA was detected in his urine sample by real-time reverse transcription polymerase chain reaction. Serological tests showed cross reactivity of IgM against the dengue virus. Zika fever could be misdiagnosed or missed and(More)
Vincristine-adriamycin-dexamethasone (VAD) regimen with intermittent high-dose dexamethasone (HD) has been used as primary chemotherapy for multiple myeloma (MM) patients who are candidates for high-dose therapy or present with renal failure. However, dexamethasone increases the risk of infection in MM patients. We retrospectively evaluated treatment(More)
Data on community-associated extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (CA-ESBLEC) infections in Japan are scarce. We compared the clinical and microbiological epidemiology of CA-ESBLEC infections with that of healthcare-associated-ESBLEC infections among 76 patients with ESBLEC infections. We identified a high prevalence (26%) of(More)
Recently, an association between granulomatous mastitis and local infection with Corynebacterium (C.) kroppenstedtii has been suggested. We herein report two cases of granulomatous mastitis resulting from C. kroppenstedtii infection in nulliparous young women with hyperprolactinemia. Both cases involved nulliparous patients with drug-induced(More)
A 59-year-old man was referred to our hospital due to nephrotic syndrome with IgM paraproteinemia. Physical examination demonstrated marked hepatomegaly and anasarca. Serum M-protein was 0.94 g/dl and urinary analysis detected the presence of Bence Jones protein. Bone marrow plasma cell count was 11.2%. Histological examination demonstrated AL-type amyloid(More)
This study aimed to describe the epidemiology of bacteraemic urinary tract infections (UTIs), especially those that were community-acquired (i.e., with no discernible healthcare-associated exposure) and caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBLPE). We also evaluated and compared empirical antimicrobial treatments(More)
