Schmidt and Holmes 7 report that worse outcomes are associated with inpatient treatment among patients with diabetic foot ulcers and Charcot osteoarthropathy. Zhu et al 8 have summarized the STAGE principles of wound treatment for clinical practice in accordance with the well-known Wagner and University of Texas classification systems for diabetic foot ulcers. They suggest that their approach will improve therapeutic strategies in this area. Burusapat 9 has retrospectively analyzed the outcomes of perforator flaps for distal lower extremity wounds and proposed surgical guidelines. Finally, Zhu and Song 10 describe a rare case of recurrent lower extremity ulcer. And Christmas is approaching. Let us enjoy holidays with the current issue.
