Wound, pressure ulcer, and burn guidelines – 3: Guidelines for the diagnosis and treatment of diabetic ulcers and gangrene, second edition

Abstract The Japanese Dermatological Association aimed to prepare a second edition of guidelines for the management of diabetic ulcer/gangrene with emphasis on the diagnosis and treatment of skin symptoms. This new edition serves as a tool to improve the quality of the diagnosis and treatment in each patient and, further, to improve the level of care for such skin conditions. All sections have been updated by collecting documents published since the publication of the first edition. In the antibacterial drug treatment for bacterial infection of ulcers, oral administration was added after consideration. In the treatment of antibacterial drugs for bacterial infection of ulcers, not only infusion but also oral administration was mentioned. In addition, clinical questions (CQs) for imaging tests for diagnosing ischemia of the limbs were newly created. The titles of some CQs were changed to conform to the actual clinical setting.
