Within each of the categories the percent of readings in which reviewers correctly reported if an induration was absent or present was . Magnetic resonance imaging is highly sensitive (100%) for necrotizing fasciitis; specificity is lower (86%).24 Extensive involvement of the deep intermuscular fascia, fascial thickening (more than 3 mm), and partial or complete absence of signal enhancement of the thickened fasciae on postgadolinium images suggest necrotizing fasciitis.25 Adding ultrasonography to clinical examination in children and adolescents with clinically suspected SSTI increases the accuracy of diagnosing the extent and depth of infection (sensitivity = 77.6% vs. 43.7%; specificity = 61.3% vs. 42.0%, respectively).26, The management of SSTIs is determined primarily by their severity and location, and by the patient's comorbidities (Figure 5).

Thank you, {{form.email}}, for signing up. Common simple SSTIs include cellulitis, erysipelas, impetigo, ecthyma, folliculitis, furuncles, carbuncles, abscesses, and trauma-related infections6 (Figures 1 through 3).

that involve specific sites (e.g., face, hands, genitalia); and that occur in children and older adults or in those who have significant comorbid illness or immunosuppression.32 In uncomplicated cellulitis, five days of treatment is as effective as 10 days.33 In a randomized controlled trial of 200 children with uncomplicated SSTIs primarily caused by MRSA, clindamycin and cephalexin (Keflex) were equally effective.34, Inpatient treatment is necessary for patients who have uncontrolled infection despite adequate outpatient antimicrobial therapy or who cannot tolerate oral antibiotics (Figure 6).
