[Efficacy and Safety of Lorazepam Intravenously Administered in Subjects with Status Epilepticus or Repetitive Seizures].

We evaluated the efficacy and safety of lorazepam (LZP) 4 mg for adults (age, 16 years old or older) or 0.05mg/kg for children (age, 3 months to less than 16 years) as a slow intravenous injection in 26 Japanese patients with status epilepticus or repetitive seizures. The proportion of patients whose initial seizure stopped within 10 minutes and who continued seizure-free for at least 30 minutes after the completion of initial dose as the primary endpoint was 48.

Nationwide surveillance of bacterial respiratory pathogens conducted by the Surveillance Committee of Japanese Society of Chemotherapy, Japanese Association for Infectious Diseases, and Japanese Society for Clinical Microbiology in 2009: general view of the pathogens' antibacterial susceptibility.

For the purpose of nationwide surveillance of antimicrobial susceptibility of bacterial respiratory pathogens from patients in Japan, the Japanese Society of Chemotherapy (JSC) started a survey in 2006. From 2009, JSC continued the survey in collaboration with the Japanese Association for Infectious Diseases and the Japanese Society for Clinical Microbiology. The fourth-year survey was conducted during the period from January and April 2009 by the three societies.

Antimicrobial efficacies of several antibiotics against uterine cervicitis caused by Mycoplasma genitalium.

Mycoplasma genitalium has been shown to be one of the pathogens responsible for uterine cervicitis by many studies. However, there are no clinical recommendations for treating M. genitalium-positive uterine cervicitis.

Investigation of the clinical breakpoints of piperacillin-tazobactam against infections caused by Pseudomonas aeruginosa.

The pharmacokinetics-pharmacodynamics (PK-PD) breakpoint of piperacillin/tazobactam (PIPC/TAZ) for hospital-acquired pneumonia (HAP) and Pseudomonas aeruginosa-induced bacteremia is controversial, since the susceptibility of P. aeruginosa to PIPC/TAZ is known to be lower than that set by the Clinical Laboratory Standards Institute (CLSI), ≤64 mg/L. The association between MIC levels and bacterial eradication after various PIPC/TAZ treatments was investigated.

Nationwide surveillance of bacterial respiratory pathogens conducted by the Japanese Society of Chemotherapy in 2008: general view of the pathogens' antibacterial susceptibility.

For the purpose of nationwide surveillance of the antimicrobial susceptibility of bacterial respiratory pathogens collected from patients in Japan, the Japanese Society of Chemotherapy conducted a third year of nationwide surveillance during the period from January to April 2008. A total of 1,097 strains were collected from clinical specimens obtained from well-diagnosed adult patients with respiratory tract infections. Susceptibility testing was evaluable with 987 strains (189 Staphylococcus aureus, 211 Streptococcus pneumoniae, 6 Streptococcus pyogenes, 187 Haemophilus influenzae, 106 Moraxella catarrhalis, 126 Klebsiella pneumoniae, and 162 Pseudomonas aeruginosa).

[Antimicrobial activity of oral quinolones against clinical isolates of Bifidobacterium group and Clostridium difficile].

Administrations of antimicrobial agent influence human intestinal flora, and sometimes lead to cause Clostridium difficile colitis (CDC). It has been well known that antimicrobial agents, such as clindamycin (CLDM), ampicillin (ABPC) and cephems, frequently cause C. difficile colitis, however, recently some respiratory quinolones, such as garenoxacin (GRNX) and moxifloxacin (MFLX), have paid to attention.

[Clinical application of azithromycin extended-release (ER) formulation to treat female sexually transmitted infection].

The prevalence of female sexually transmitted infection (STI) in Japan is in the decreasing tendency after 2002, however it still actualizes as a social problem. Azithromycin, which is 15-member macrolide antimicrobial agent, has indication to treat the chlamydia STI in a single dose of 1 g. In April 2009, a single dose of 2 g of azithromycin extended release (ER) formulation, which is improved formulation by the viewpoint of pharmacokinetics-pharmacodynamics, was approved and has indications to treat not only chlamydial STI but also gonococcal STI.

[Antifungal susceptibility of Candida species isolated from patient with invasive fungal peritonitis and investigation on clinical breakpoints of itraconazole].

We investigated antifungal susceptibility of 96 Candida species strains (37 strains of Candida albicans, 30 of Candida glabrata, 16 of Candida tropicalis and 13 of Candida parapsilosis) isolated from patients with invasive fungal peritonitis. Antifungal activity showed micafungin (MCFG), voriconazole (VRCZ)>itraconazole (ITCZ)>fluconazole (FLCZ). Judged by clinical breakpoints of Clinical and Laboratory Standards Institute (CLSI), FLCZ-resistant C.
