QuantiFERON-TB gold in-tube has been used for screening latent tuberculosis infection in newly employed health care workers in Japan. There have been a few studies concerning quality control. We retrospectively analysed QuantiFERON-TB gold in-tube results in a hospital in Japan. Interferon-γ values in three blood collection tubes for QuantiFERON-TB gold in-tube were analysed in association with the positivity rate. The data set consisted of health care workers aged 20-29 years during the 7 years between 2010 and 2016...

In this research, we analyzed the main sequence types (ST) and ST complexes of human- and chicken-derived isolates of Campylobacter jejuni in Japan by using multilocus sequence typing (MLST). We also analyzed lipooligosaccharide biosynthesis locus classes (LOS locus classes) and the numbers of isolates carrying genes coding resistance factors against various antibiotics, and observed their relationships. ST-21 complex was the main ST complex in isolates from humans (n = 38) and chickens (n = 25). None of the isolates showed resistance to imipenem, chloramphenicol, or erythromycin...

BACKGROUND: The immunoglobulin (Ig) G avidity index (AI) is useful to detect primary cytomegalovirus (CMV) infection. However, because IgG matures with time, this index is not useful to detect a primary infection, unless measured at an appropriate time. OBJECTIVES: We aimed to clarify the difference between using IgG AI and IgM positivity according to the stage of pregnancy to identify congenital CMV infection risk. STUDY DESIGN: We collected the serum samples from 1115 pregnant women who underwent maternal screening for primary infection (n = 956) and were referred to our hospital because of CMV IgM positivity (n = 155) or had abnormal fetal ultrasonography findings (n = 4)...

INTRODUCTION: Pharmacokinetic of vancomycin in very low birth weight neonates showed big variety, and limited data were available due to very minor population. These facts make it difficult to adjust its optimal initial dosage. Therefore, this study was to develop optimal dosing regimen of vancomycin in very low birth weight neonates. METHODS: Between 2010 and 2015, low birth weight neonates (≤1500 g) were included in a population pharmacokinetics analysis. Based on the pharmacokinetic parameters we estimated, we simulated individual blood concentrations of vancomycin and evaluated the probability of its pharmacokinetics/pharmacodynamics (PK/PD) target attainment, such as 24-h area under the concentration-time curve (AUC24)/MIC (≥400) and blood trough concentration (10-20 μg/mL), as primary measure for several dosing regimens by Monte Carlo simulation method...

We report a rare case of intracranial hypertension following high dose cytosine arabinoside (HiDAC) in a 20-year-old man, with precursor B-cell acute lymphoblastic leukemia (ALL). A five drug induction protocol for ALL was initiated; post induction consolidation was with HiDAC (3 g/m(2) IV every 12 h on days 1, 3 and 5). Post consolidation, cytogenetic remission was attained and he received an intensification and maintenance regimen for ALL, for a period of approximately 24 months. Four months following the completion of his treatment, the patient relapsed within the central nervous system (CNS)...

This study was to evaluate the loading does of daptomycin, a novel lipopeptide antibacterial active against Gram-positive pathogens, on clinical efficiency. We divided patients received daptomycin therapy into 2 groups. One of two groups comprised patients received the loading dose of daptomycin on day 1 (group 1) and the other group received normal dosage (4-6 mg/kg/day) (group 2). Inflammatory markers were assessed at least 3 days before daptomycin therapy started as their baseline, and 2 weeks from daptomycin therapy started for the evaluation of clinical efficacy...

The number of patients with acute cystitis caused by extended spectrum β lactamase (ESBL)-producing Escherichia coli (E. coli) is increasing gradually. Although it is reported that ESBL-producing E. coli are sensitive to faropenem (FRPM), there are few clinical studies on the efficiency of FRPM against acute cystitis caused by the bacteria. Therefore, we retrospectively reviewed the medical charts of patients with acute cystitis caused by ESBL-producing E. coli who were treated with the oral antimicrobial agent faropenem (FRPM) in our institution from June 2011 to May 2015...

Mycobacterium fortuitum is a rapidly growing mycobacterium (RGM) that is an uncommon cause of healthcare-associated infections. The most common infections caused by M. fortuitum include skin, soft tissue, and catheter-related infections. Although occasionally cultured from sputum samples, M. fortuitum is a rare cause of pulmonary disease. We report a case of M. fortuitum empyema associated with an infected pleural catheter and review M. fortuitum pulmonary infections.

Pyomyositis is classified into two main types: tropical and non-tropical. Non-tropical pyomyositis occurs among various immunocompromised patients, and Staphylococcus aureus has been reported as the most common pathogen. Pyomyositis caused by Streptococcus pneumoniae is uncommon, and has not been previously reported after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Here, we report a unique case with pyomyositis caused by S. pneumoniae in the bilateral erector spinae muscles 34 months after allo-HSCT...
