Prosthetic joint infection of the knee - arthroscopic biopsy identifies more and different organisms than aspiration alone.

Background: Prosthetic joint infection (PJI) causes significant morbidity and mortality following knee replacement surgery. Identifying causative organisms and antibiotic sensitivities is critical in increasing the chance of infection eradication. This study investigated whether biopsy alone was superior to aspiration alone for serological diagnosis in PJI following knee replacement.

Bilateral testicular torsion in a 36-week neonate.

A male neonate born after uncomplicated vaginal delivery at 36 weeks' gestation was noted to have large and firm testicles bilaterally on routine examination. A testicular ultrasound scan was subsequently organised that showed detailed appearances consistent with bilateral testicular torsion. This was thought to have taken place antenatally and as such was unfortunately not suitable for intervention.
