Surgical debridement, maggot therapy, negative pressure wound therapy, and silver foam dressing revive hope for patients with diabetic foot ulcer: A case report

Abstract

Introduction and importance Diabetic foot ulcers (DFUs), as one of the most debilitating complications of diabetes, can lead to amputation. Treatment and management of d DFUs are among the most critical challenges for the patients and their families. Case presentation The present case report is of a 63-year-old man with a 5-year history of uncontrolled type 2 diabetes who has had DFU for the past three years on three sites of the left external ankle in the form of two deep circular ulcers with sizes of 6 × 4 cm and 6 × 8 cm, the sole as a superficial ulcer with a size of 6 × 3 cm, and the left heel as a deep skin groove. Moreover, the left hallux was completely gangrenous. The patient's ulcers were infected with Staphylococcus aureus and multidrug-resistant Pseudomonas aeruginosa . The patient was transferred to our wound management team. DFU was treated and managed using a combination of surgical debridement, maggot therapy, the Negative Pressure Wound Therapy (NPWT), and silver foam dressing. After three months and ten days, the patient's ulcers completely healed, and he was discharged from our service with the excellent and stable condition. Clinical discussion DFUs are caused by various pathological mechanisms, the monotherapy strategy would lead to a very low level of recovery. Therefore, DFU management requires multimodal care and interdisciplinary treatment. Conclusion Based on the present case report study's clinical results, wound-care teams can use the combination therapy applied in this case report to treat refractory DFU.

Targeting Nrf2-Mediated Oxidative Stress Response in Traumatic Brain Injury: Therapeutic Perspectives of Phytochemicals

“…At present, the therapeutic strategies for TBI include hyperbaric oxygen therapy (HBOT), hyperventilation and hypertonic therapy, noninvasive brain stimulation, drug therapy, and biological therapy [ 27 ]. Most importantly, the combinational use of novel biological reagents (genes and stem cells) and pharmacological intervention preparations can decrease the complications and mortality of TBI [ 28 ].…”

Glucose and MMP-9 dual-responsive hydrogel with temperature sensitive self-adaptive shape and controlled drug release accelerates diabetic wound healing

“…Consequently, MMP-9 is regarded as a novel target for the treatment of chronic diabetic wounds [ 15 ]. In addition, another factor that affects the healing of diabetic wounds is the irregular shape of wounds after removing the necrotic tissues; traditional clinical dressings give rise to a higher risk of infection due to their quite unfitting shape of the irregular wounds [ [16] , [17] , [18] , [19] ]. Overall, it is necessary to develop a wound dressing that fully adapts to the wound shape as well as regulates the level of MMP-9 and glucose, thereby accelerating the healing of chronic diabetic wounds.…”
