Clinical experience with surgical debridement and simultaneous meshed skin grafts in treating biofilm-associated infection: an exploratory retrospective pilot study.

Clinical experience with surgical debridement and simultaneous meshed skin grafts in treating biofilm-associated infection: an exploratory retrospective pilot study. J Plast Surg Hand Surg. 2019 Oct 01;:1-8 Authors: Namgoong S, Jung SY, Han SK, Kim AR, Dhong ES Abstract Current treatment guidelines for biofilm-associated infections (BAI) recommend repeated sharp/surgical debridement followed by treatment with antimicrobial agents until the wound becomes self-sustaining in terms of a positive wound-healing trajectory. However, complete removal of a biofilm is unlikely, and biofilms reform rapidly. We have treated BAI in patients with chronic diabetic ulcers using a meshed skin graft combined with negative pressure wound therapy (NPWT) immediately after surgical debridement, rather than waiting until the development of clean and healthy granulation tissue; the purpose of this exploratory study was to report the clinical results of this treatment strategy. This retrospective study included 75 patients with chronic diabetic ulcers who were treated for BAI by using surgical debridement, simultaneous meshed skin grafts, and NPWT. Healing time along with the percentage of complete wound closure within 12 weeks were evaluated; bacteria isolated from the wounds and their relation to the wound healing rate were investigated. All 75 wounds healed successfully, and the mean time for complete wound healing was 3.5 ± 1.8 weeks. In par...

In conclusion, there is solid evidence that obesity deregulates cellular mechanisms related to nutrient sensing. Altered Intercellular Communication It is accepted that aging impacts the organism at the cellular level, but also decreases the capacity of cells of an organism to interact. During aging, there is a decreased communication at the neuronal, neuroendocrine, and endocrine levels. Two of the most compelling examples of impaired communication are inflammaging and immunosenescence. The inflammaging phenotype results in elevated cytokines. These cytokines can accelerate and propagate the aging process. T...

Bioprinting directly onto the body seems a logical evolution of the state of the art in this part of the field, given the emerging ability to bioprint full thickness skin, or at least a living structure very close to that. It is interesting to consider how bioprinting in situ could be made to work for internal organs. We might envisage something akin to keyhole surgery with a machine-guided printing head. The easier initial applications might include printing a patch of tissue directly onto the heart, akin to the present development of heart patches that are grown outside the body and then transplanted. The Lygenesis appro...

Publication date: Available online 21 December 2018Source: The Journal of Foot and Ankle SurgeryAuthor(s): Tea Nguyen, Edgardo R. Rodriguez-CollazoAbstractThe purpose of this study was to demonstrate use of a distally based peroneus brevis muscle flap in high-risk patients with diabetes and peripheral vascular disease for limb salvage of nonhealing heel ulcerations. Seventeen patients were referred for a below-knee amputation because of nonhealing heel ulcerations and peripheral vascular disease. As a last resort, 17 distally based peroneus brevis muscle flaps were elevated in 17 patients with full-thickness heel ulceratio...

Hyalomatrix, Product nos. 651105, 651103, 651104, and 651301 Product Usage: Hyalomatrix is a bi-layered, sterile, flexible, and comfortable wound dressing that acts as an advanced wound care device. It is comprised of a non-woven pad entirely composed of HY AFF 11, a benzyl ester of hyaluronic acid, and a semipermeable silicone membrane, which controls water vapor loss, provides a flexible covering for the wound surface, and adds increased tear strength to the device. The HYAFFl 1 wound contact layer biodegradable matrix acts as a scaffold for cellular invasion and capillary growth. Hyalomatrix is indicated for the managem...

We report the application of a free vascularized medial femoral condyle flap to prevent the recurrence of pressure ulcer in a patient with diabetic foot syndrome. Our patient had type 2 diabetes and presented with pressure ulcers and osteomyelitis of metatarsal heads 2 and 3 after a great toe amputation. We chose to use a medial femoral condyle flap as a damper in the area of the metatarsal heads because of the relatively young age and good vascularity of our patient. We shaped the graft like a ski to distribute the pressure and prevent perforation of the plantar skin. Good results were achieved for wound healing, pain red...

AbstractSkin graft is a standard therapeutic technique in patients with deep ulcers, but managing donor site after grafting is very important. Although several modern dressings are available to enhance the comfort of donor site, using techniques that accelerate wound healing may enhance patient satisfaction. Low-level laser therapy (LLLT) has been used in several medical fields, including healing of diabetic, surgical, and pressure ulcers, but there is not any report of using this method for healing of donor site in burn patients. The protocols and informed consent were reviewed according to Medical Ethics Board of Shahid ...

CONCLUSIONS: Treatment for DFUs should start when a possible pre-ulcer is noticed. This prophylactic treatment may reduce development of more severe DFUs. Once a DFU has developed, care should be optimized for both the patient and the wound bed. While these treatment recommendations are focused solely on DFUs, they may be expanded for use in other foot/leg pressure ulcers. PMID: 29091034 [PubMed - as supplied by publisher]
