Biapenem (L-627) was evaluated for its safety and efficacy in 27 children with various bacterial infections. L-627 was effective in cases with osteomyelitis due to Staphylococcus aureus, pneumonia and purulent meningitis due to penicillin-resistant Streptococcus pneumoniae, and urinary tract infections due to Enterococcus faecalis, Escherichia coli, or Pseudomonas aeruginosa. However, L-627 failed to produce good responses in 2 of 7 cases of Haemophilus influenzae infections. Pharmacokinetic parameters of 30-minutes infusion of 12 mg/kg were as follows: Cmax 29-46 micrograms/ml, T 1/2 0.68-0.94 hr. Adverse reactions were minimal. These data suggest that L-627 is safe in children, and is valuable especially for treatment of infections in immunocompromised hosts and infections due to multiply resistant bacteria.

Objective: is usually found in urogenital tract infections and is associated with several extra-genitourinary infections, including septic arthritis, bacteremia, and meningitis. Here, we report a rare case of induced bloodstream infection with thoracic inflammation in a surgical patient.
Methods: A 56-year-old male who underwent surgery for multiple pelvic and rib fractures developed fever, pleural effusion, and wound exudation despite receiving prophylactic anti-infection treatment with cefotiam.

Background: Tropheryma whipplei pneumonia is an infrequent medical condition. The clinical symptoms associated with this disease are nonspecific, often resulting in misdiagnosis or missed diagnosis. Therefore, sharing and summarizing the experiences in the diagnosis and treatment of this disease can deepen global understanding and awareness of it.

Article Synopsis
- The report discusses a case of an elderly male patient with multiple health issues who developed a rare condition called bacteremia associated with a particular strain of bacteria, ST81.
- He initially presented with a sudden fever, prompting diagnostic tests that confirmed the bacteremia.
- After treatment with a combination of antibiotics (vancomycin and biapenem), the patient recovered and was discharged, highlighting the importance of monitoring such infections in high-risk patients.

Department of Infectious Diseases, Okayama University Hospital.
Article Synopsis
- The study investigates carbapenemase-producing Enterobacterales (CPE) at Okayama University Hospital over 5 years (2013-2018), revealing a variety of CPE isolates with different phenotypic and genetic characteristics.
- Eight CPE isolates were identified, mainly carrying blaIMP-1 and blaIMP-6 genes, with significant diversity in bacterial species and carbapenem susceptibility patterns.
- The findings highlight the importance of continuous genetic surveillance and customized infection control measures to combat the spread of CPE.

Article Synopsis
- Biapenem has been approved for treating complicated urinary tract infections in India, but its effectiveness against ESBL-producing Enterobacterales and Pseudomonas aeruginosa in vitro has not been previously studied.
- The study assessed the susceptibility of various isolates to biapenem using broth microdilution and identified resistance genes through multiplex PCR.
- Results showed biapenem's in-vitro activity is comparable to meropenem against resistant E. coli, K. pneumoniae, and P. aeruginosa, with a recommended testing concentration of 10 μg for accurate results.
