For example, diabetes increases the risk of infection-associated complications fivefold.14 Comorbidities and mechanisms of injury can determine the bacteriology of SSTIs (Table 3).5,15 For instance, Pseudomonas aeruginosa infections are associated with intravenous drug use and hot tub use, and patients with neutropenia more often develop infections caused by gram-negative bacteria, anaerobes, and fungi.

Plain radiography, ultrasonography, computed tomography, or magnetic resonance imaging may show soft tissue edema or fascial thickening, fluid collections, or soft tissue air. If present, consider sepsis, necrotizing infection, and lymphadenitis. 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).
