Clin Exp Pediatr. 2025;68(9):700-711.   Published online August 26, 2025
Question: What pharmacological strategies can limit ischemia-reperfusion injury in pediatric patients with testicular torsion?
Finding: In a rat model of testicular torsion, linezolid reduced oxidative stress, inflammation, and tissue injury via the Toll-like receptor 4/mitogen-activated protein kinase/nuclear factor kappa beta pathway.
Meaning: Linezolid may offer a pharmacological approach to attenuate testicular damage in pediatric patients with testicular torsion, warranting further clinical investigation.
Evolving treatment strategies for invasive Streptococcus pyogenes in children in the postpandemic era
Laura Buricchi, Giuseppe Indolfi, Marco Renni, Elisabetta Venturini, Luisa Galli, Elena Chiappini
Background: Streptococcus pyogenes (group A Streptococcus [GAS]) is a common cause of bacterial pharyngitis and skin infections in children that can lead to severe and invasive GAS (iGAS) infections. The sudden acute respiratory syndrome coronavirus 2 pandemic coincided with an increase in iGAS cases, with emerging serotypes and risk factors like age, reduced postpandemic immunity, and viral coinfections. The treatment...
