Community associated methicillin resistant staphylococcal infections in a pediatric urology practice.
OBJECTIVE
Methicillin resistant Staphylococcus aureus is a virulent organism that has seen a rapid increase in prevalence. Community associated methicillin resistant S. aureus is discussed frequently in the infectious disease community. However, there has been little mention of this entity in the urological literature.


METHODS
We reviewed the records of patients presenting with skin/soft tissue infections or documented methicillin resistant S. aureus infection treated at an academic pediatric urology practice between October 2004 and August 2006.


RESULTS
A total of 12 patients were included (33% female, 67% male). Mean patient age was 49 months (range 8 to 202). Of the patients 11 (92%) presented with spontaneous infection and 1 (8%) presented with a wound infection. Abscess location was inguinal in 4 patients (33%), scrotal in 3 (25%), perineal in 2 (17%), perinephric in 2 (17%) and labial in 1 (8%). The most common presenting sign at referral was fluctuance (30%). While all patients eventually required surgical drainage, initial treatment by the primary care physician consisted of observation on oral antibiotics in 7 patients (58%). A total of 10 cultures (83%) revealed methicillin resistant S. aureus and 2 cultures (17%) were negative. Mean hospital stay was 5 days (range 0 to 16). Postoperatively, most patients (58%) were discharged home on oral trimethoprim-sulfamethoxazole. Mean followup was 4 months (range 0 to 15). Recurrence was seen in 3 patients at 1 to 15 months postoperatively (mean 6.3).


CONCLUSIONS
Methicillin resistant S. aureus is increasing in the community and will likely be seen more often in pediatric and adult urological practices. The regional differences among bacterial strains make a standardized approach to these cases difficult. However, increased awareness of this virulent organism is necessary to deliver prompt and successful treatment.
