Background In patients with lower limbs wounds from vasculitis reconstructive surgery with skin grafts can be considered, but this treatment likely fails because of the position, width, and depth of the lesion(s). In these patients a new therapeutic prospect is the use of a dermal matrix that stimulates the production of endogenous collagen before repair with skin graft autografting. Integra® i...

METHODS: Immunocompromised nude-mice underwent external beam irradiation of the scalp. Five weeks later, mice either received seven deferoxamine treatments (1mg in 100ul) or saline subcutaneously to the irradiated area every other day. Laser Doppler analysis (LDA) was recorded prior to irradiation, following irradiation, and 24 hours following each treatment. Human fat grafts were then injected...

Osteomyelitis of the calcaneus is a difficult problem to manage. Patients affected by osteomyelitis of the calcaneus often have a below-the-knee amputation because of their comorbidity. In this article, we present seven cases of heel ulcerations with chronic osteomyelitis treated with Integra(®) Dermal Regeneration Template, skin graft and negative pressure wound therapy after partial tangentia...

Dermatofibrosarcoma protuberans (DFSP) is a rare disease of dermal fibroblastic origin that accounts for less than 5% of all soft tissue sarcomas in adults. DFSP grows slowly and is an asymptomatic lesion at the initial diagnosis. Herein, we report a case of multiple pedunculated nodules as a variant of DFSP. A 47-year-old man presented with a 7-month history of multiple well-circumscribed, fir...

The reconstruction of lower third of the leg is one of the most challenging problems for plastic and reconstructive surgeons and current approaches are still disappointing. We show an easy option to obtain a coverage of traumatic pretibial defects with good aesthetic and functional results: the association of negative pressure wound therapy, acellular dermal matrix, and skin graft. The choice o...

We present a case of scalp reconstruction using Integra and split skin grafting after extensive excision of melanoma in a previously irradiated field. Radical resection of malignancy and application of Integra, a dermal substitute, was performed. Following histological confirmation of complete excision, a split-thickness skin graft (SSG) was applied. After 14 months the patient remains fully he...

objective: objective: dermal papilla and hair epithelial stem cells regulate hair formation and growth cycle. damage to or losing of these cells can cause hair loss. although several studies have claimed to reconstitute hairs using rodent cells in animal model, a stable human hair follicle reconstitution protocol needs more studies. here in this study we evaluated hair induction through injecti...
