Abstract

Purpose: This retrospective monocentric study aims to describe the characteristics of neurosurgical site infections (n-SSI) in neurooncological pediatric patients. The primary goal was to assess infection rates and identify common pathogens in this population.

Methods: We considered pediatric patients (0-18 years) who underwent neurosurgery for brain tumors at Meyer Children's Hospital in Florence between January 1, 2017, and December 31, 2021. Children with suspected/confirmed n-SSI were included. Data were retrospectively collected from patients' medical records, and covered tumor and surgery type, presence of foreign bodies, microbiological findings, and treatment. Infections were classified into categories according to literature. Statistical analysis was performed using GraphPad Prism. A p value of < 0.05 was considered significant.

Results: Of 352 children undergoing neurosurgery, 43 (12.22%) had suspected/confirmed n-SSI, with a confirmed infection rate of 4%. The most frequent n-SSI was postoperative meningitis (37.2%), followed by wound infections (25.6%). A foreign body was present in 74.4% of cases. The most prevalent pathogens were Staphylococcus aureus (40%) and coagulase-negative staphylococci (33%). Lumbar puncture (LP) performed before antibiotics significantly increased pathogen isolation (p = 0.01). Most patients (95.3%) had fever, and 53.5% had CSF leakage. Antibiotic therapy was administered in all cases, and 65.1% required therapy adjustment. No significant correlation was found between foreign body and clinical symptoms or microbiological positivity.

Conclusion: The study reveals a high rate of n-SSI, emphasizing the importance of early diagnostic measures like LP to improve microbiological diagnosis and optimize antimicrobial treatment. The most frequent pathogen was S. aureus; however, the absence of methicillin-resistant strains is notable. These findings highlight the role of a multidisciplinary approach in managing n-SSI and the potential for n-SSI to delay adjuvant cancer treatments.
