Methicillin-resistant Staphylococcus aureus infections in 2 pediatric outpatients

Area of Science:

• Pediatrics
• Infectious Diseases
• Medical Microbiology

Background:

• Methicillin-resistant Staphylococcus aureus (MRSA) is a growing concern in pediatric populations.
• Early identification and appropriate treatment are crucial for managing MRSA infections.

Observation:

• Two pediatric cases of unsuspected MRSA infections are presented: an infant with cervical adenitis and a young child with a deep toe infection.
• Both patients initially received outpatient oral cephalosporin therapy but showed no improvement.

Findings:

• Both children required hospitalization and surgical drainage for their infections.
• Cultures obtained during surgery confirmed MRSA in both cases.
• Neither patient had identifiable risk factors typically associated with MRSA acquisition.

Implications:

• These cases suggest that MRSA should be considered in pediatric patients with presumed staphylococcal infections who do not respond to standard oral cephalosporin treatment.
• Clinicians should maintain a high index of suspicion for MRSA in pediatric patients, even in the absence of typical risk factors.
• Prompt diagnosis and surgical intervention are critical for successful outcomes in severe pediatric MRSA cases.
