The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score was introduced as a tool for distinguishing necrotizing fasciitis from other soft tissue infections. We retrospectively analyzed 11 patients with necrotizing fasciitis and 110 patients with severe cellulitis between 2005 and 2012 to validate the usefulness of the LRINEC score. T...

Background: Negative pressure wound therapy (NPWT) has been frequently used in the management of various wounds, including diabetic ulcers, pressure ulcers and post operative wounds.
