Background: Two-stage revision arthroplasty remains the main surgical strategy for the treatment of prosthetic joint infections (PJI). Sonicate fluid culture has improved sensitivity compared to standard periprosthetic tissue culture, but its usefulness is questionable during the second stage of revision arthroplasty.

Material And Methods: Twenty-seven patients with prosthetic joint infection were investigated.

BACKGROUND Recent studies have shown that up to 25% of sepsis cases originate in the urinary tract. Urosepsis can be associated with cystitis, lower urinary tract infections (UTIs), and upper UTIs and is most commonly caused by gram-negative bacteria. This retrospective study from a urology center in southern Poland, was conducted between 2017 and 2020 and aimed to investigate the causes, microbiology laboratory findings, and management in 138 patients with UTIs and urosepsis.

Article Synopsis
  • The study investigated an outbreak of rifampicin-resistant ribotype 027 (RT 027) fecal isolates in a Polish hospital from late 2017 to early 2018 using multilocus variable tandem repeat analysis (MLVA).
  • Twenty-nine fecal isolates were analyzed, revealing that all strains contained specific toxin genes and had varying antibiotic resistance profiles, including significant resistance to imipenem (97%) and rifampicin (45%).
  • The findings indicated a transmission outbreak of multidrug-resistant RT 027, likely due to poor hygiene and spore presence in the hospital, highlighting the need for further research into the resistance mechanisms.

Article Synopsis
  • Researchers collected 116 environmental samples from a clinical hospital to study the presence of Clostridium species between 2017 and 2019.
  • They successfully isolated six strains of C. difficile and twelve strains of C. perfringens from these samples.
  • The study highlights that antibiotic-resistant Clostridium species were prevalent in the hospital environment, indicating the need for using specialized media like C diff Banana Broth™ for accurate detection.
