In clinical practice, skin defects occur frequently due to various kinds of acute and chronic diseases. The standard treatment for these wounds is autografting, which usually results in complications such as scar formation and new wounds at donor sites. The advent of dermal substitutes has provided a novel method for wound repair, and rapid angiogenesis of the dermal substitutes is crucial for the graft to take. At present, many strategies have been developed to improve the process of vascularisation, some of which have shown promising potentials, but they could be very far from clinical applications. Most recently, negative-pressure wound therapy (NPWT) has been used extensively in clinical practice for wound care and management. It has been reported that NPWT reduces the time required for vascular ingrowth into the dermal substitute and improves graft take, indicating great potentials for wound repair. This article presents a comprehensive overview of the combined use of NPWT and dermal substitutes for tissue repair and regeneration. Relative concerns and prospects are also discussed.

Deep intermediate burns of the hand are a challenge for both the functional and aesthetic result. In this study we compare the efficacy of early selective enzymatic escarolysis followed by the application of stromal vascular fraction (SVF) extracted from autologous adipose tissue on a dermal substitute scaffold (DS) versus reconstruction by partial thickness skin grafts (PTSG). We enrolled all patients admitted to our referral Burn Center from September 2020 to January 2022 with deep intermediate burns of the hands: clinical data were collected, then the first group of 4 patients were treated with PTSG surgical reconstruction, and the second group of 7 patients with DS+SVF.

Dermal substitutes offer a valuable tool in soft-tissue reconstruction, reducing the need for donor site tissue and its associated complications. However, conventional approaches often require multiple surgeries. This study aimed to compare the effectiveness of a single-stage procedure combining dermal substitute and skin grafting with hyperbaric oxygen (HBO) therapy to the standard multistage protocol.

Urethrovaginal fistulas are rare complications often arising from urethrovaginal injuries commonly due to obstetrical trauma, urethral surgeries, pelvic fractures, or neoplastic treatments. Here, we present a unique case involving a 23-year-old female patient with a large urethrovaginal fistula and complete anterior vaginal wall sloughing following prolonged obstructed labor. Nine months post-cesarean, she reported urine leakage via the vagina upon catheter removal, which intensified in an erect posture.

This study presents the development of thiol-maleimide/thiol-thiol double self-crosslinking hyaluronic acid-based (HA) hydrogels for use as dermal fillers. Hyaluronic acid with varying degrees of maleimide substitution (10%, 20%, and 30%) was synthesized and characterized, and HA hydrogels were fabricated using two molecular weights of four-arm polyethylene glycol (PEG10K/20K)-thiol as crosslinkers. The six resulting HA hydrogels demonstrated solid-like behavior with distinct physical and rheological properties.

Deep dermal and full-thickness burns often result in scar sequelae such as contractures, hypertrophy, pain and itching following split-thickness skin grafting. Dermal substitutes are currently employed alongside split-thickness skin grafting to enhance clinical outcomes, though their indications remain a subject of ongoing debate. This systematic review aims to clarify the indications for the application of dermal substitutes in burn patients, in both acute and reconstructive settings.
