Abstract
Pathogenic bacterial infections of skin wounds have caused a significant threat to clinical treatment and human life safety. Here, we develop a bactericidal hydrogel dressing consisting of a polyacrylamide (PAM) hydrogel framework with in situ surface-deposition of iron-dopped polydopamine (FePDA). The prepared hydrogel dressing (FePDA-PAM) has a compact surface, good tensile strength, and excellent elastic recovery ability. The introduction of Fe3+ ions improve the photothermal therapy (PTT) efficiency of the PDA and endow the hydrogel dressing with chemodynamic therapy (CDT) properties. In vitro experiments show that the antibacterial effect of FePDA-PAM hydrogel on Staphylococcus aureus reach nearly 100% under the combined action of H2O2 and 808 nm near-infrared (NIR) laser, indicating an excellent combined antibacterial property of PTT and CDT. Furthermore, the FePDA-PAM + H2O2 + NIR treatment group in the in vivo antibacterial experiments displays lowest relative wound area and optimal wound healing within 5 days of treatment, thereby indicating the intensive skin wound disinfection. To summarize, the FePDA-PAM hydrogel has simple preparation and good biosafety. It may serve as a potential wound dressing for the combined PTT/CDT dual-mode antibacterial therapy.

Abstract
Skin regeneration is a quite complex process. Epidermal differentiation alone takes about 30 days and is highly regulated. Wounds, especially chronic wounds, affect 2% to 3% of the elderly population and comprise a heterogeneous group of diseases. The prevailing reasons to develop skin wounds include venous and/or arterial circulatory disorders, diabetes, or constant pressure to the skin (decubitus). The hallmarks of modern wound treatment include debridement of dead tissue, disinfection, wound dressings that keep the wound moist but still allow air exchange, and compression bandages. Despite all these efforts there is still a huge treatment resistance and wounds will not heal. This calls for new and more efficient treatment options in combination with novel biocompatible skin scaffolds. Cold atmospheric pressure plasma (CAP) is such an innovative addition to the treatment armamentarium. In one CAP application, antimicrobial effects, wound acidification, enhanced microcirculations and cell stimulation can be achieved. It is evident that CAP treatment, in combination with novel bioengineered, biocompatible and biodegradable electrospun scaffolds, has the potential of fostering wound healing by promoting remodeling and epithelialization along such temporarily applied skin replacement scaffolds.

Abstract
The treatment of patients with chronic wounds is a multiprofessional challenge. Based on a comprehensive diagnosis and integrated into a causal treatment concept, patients should always be treated with a modern wound therapy. This wound therapy should try to take into account many different factors such as the wound healing phases, infection status, exudate levels, but also individual patient wishes. Especially in the case of chronic wounds of the lower extremities and edema, compression therapy is also very important for therapy and recurrence prophylaxis. In addition, the pain, which is usually very distressing, should be recorded and adequately treated or avoided. Modern moist wound therapy can then support the healing of patients with chronic wounds, reduce complications and thus improve their quality of life.

Abstract
BACKGROUND Cold atmospheric plasma (CAP, i.e. ionized air) is an innovating promising tool in reducing bacteria. OBJECTIVE We conducted the first clinical trial with the novel PlasmaDerm® VU-2010 device to assess safety and, as secondary endpoints, efficacy and applicability of 45 s/cm(2) cold atmospheric plasma as add-on therapy against chronic venous leg ulcers. METHODS From April 2011 to April 2012, 14 patients were randomized to receive standardized modern wound care (n = 7) or plasma in addition to standard care (n = 7) 3× per week for 8 weeks. The ulcer size was determined weekly (Visitrak® , photodocumentation). Bacterial load (bacterial swabs, contact agar plates) and pain during and between treatments (visual analogue scales) were assessed. Patients and doctors rated the applicability of plasma (questionnaires). RESULTS The plasma treatment was safe with 2 SAEs and 77 AEs approximately equally distributed among both groups (P = 0.77 and P = 1.0, Fisher's exact test). Two AEs probably related to plasma. Plasma treatment resulted in a significant reduction in lesional bacterial load (P = 0.04, Wilcoxon signed-rank test). A more than 50% ulcer size reduction was noted in 5/7 and 4/7 patients in the standard and plasma groups, respectively, and a greater size reduction occurred in the plasma group (plasma -5.3 cm(2) , standard: -3.4 cm(2) ) (non-significant, P = 0.42, log-rank test). The only ulcer that closed after 7 weeks received plasma. Patients in the plasma group quoted less pain compared to the control group. The plasma applicability was not rated inferior to standard wound care (P = 0.94, Wilcoxon-Mann-Whitney test). Physicians would recommend (P = 0.06, Wilcoxon-Mann-Whitney test) or repeat (P = 0.08, Wilcoxon-Mann-Whitney test) plasma treatment by trend. CONCLUSION Cold atmospheric plasma displays favourable antibacterial effects. We demonstrated that plasma treatment with the PlasmaDerm® VU-2010 device is safe and effective in patients with chronic venous leg ulcers. Thus, larger controlled trials and the development of devices with larger application surfaces are warranted.

Abstract
Chronic wounds remain a major challenge in modern medicine and represent a significant health care burden. Several treatments have been suggested, but without a full understanding of the exact mechanism by which chronic wound occurs. Numerous studies have shown that mesenchymal stem cells/multipotent mesenchymal stromal cells (MSCs) may have therapeutic potential in healing cutaneous chronic wounds through various mechanisms. So far, a series of hypotheses have been proposed, but a holistic image of them is lacking. This review provides a systematic analysis of recent research in animal models and preclinical or clinic trails to evaluate the potential role of MSCs in chronic cutaneous wound healing. Most important, we highlight how mesenchymal stem cells could potentially revolutionize our approach to treating cutaneous chronic wounds. Special attention should be focused on ongoing research regarding the challenges in using and prospects of MSCs in clinical settings.

Abstract
CASE REPORT We report on a 36-year old patient with a chronic leg ulcer at the right malleolus lateralis which persists since nine month and causes distinct pain. Furthermore telengiectatic erythema in terms of a naevus flammeus could be found at the right leg and foot as well as genital and gluteal. By birth the right leg of the patient was longer than the other one. In spite of initiation of several therapies the ulcer was refractory to different therapies. The clinical diagnosis of a chronic venous insufficiency of the right leg was clearly proven by apparative diagnostic. In consequence of all findings we diagnosed a Klippel-Trenaunnay syndrome consisting of the typical trias of naevus flammeus, hemihypertrophie of bone and soft tissue as well as angiodysplasies with a distinct chronic venous insufficiency. CONCLUSION The presented case describes a patient with a Klippel-Trenaunnay syndrome as a seldom cause of a chronic leg ulcer. Although it is a very rare cause for a chronic wound it should be known by physicians to be considered in the differential diagnosis process.

Abstract
BACKGROUND Octenisept, containing 0.1 % octenidine/2 % phenoxyethanol, is a widely used antiseptic in modern wound management. It is considered to have a very low allergenic potential. Thus far, neither allergic nor irritant contact dermatitis to the product has been described. PATIENTS AND METHODS Chronic wounds in 251 patients were treated with Octenisept; 11 developed signs of contact dermatitis. The symptoms improved after discontinuation of the antiseptic. Eight of these patients were patch tested to the antiseptic and its components. RESULTS The eight patients all showed a positive reaction to the product. In at least three cases a reaction to the components cocamidopropyl betaine and phenoxyethanol was found, but not to octenidine dihydrochloride. CONCLUSIONS In this cohort, more than three percent of the treated patients developed a contact dermatitis to the antiseptic. However, the differentiation between allergic and irritant contact dermatitis towards the ingredients of the antiseptic remains problematic.

Abstract
Although the positive effects of negative pressure-therapy in wound-healing has been well known for several decades, the first paper on the now widely used vacuum systems was published ten years ago. Since then vacuum-therapy has been widely used in patients with"hard-to-heal" wounds, including dermatologic patients. Although there is still a lack of relevant comparative prospective controlled clinical trials, vacuum-therapy seems to accelerate the healing process in chronic wounds in both the granulation and epithelialization phases. Therefore, following debridement, vacuum-therapy can be considered as the therapy of choice for many patients with chronic wounds.

Abstract
Obtaining stable, durable, and functional wound closure of a diabetic foot wound or open pedal amputation through plastic surgical techniques is essential to limit the potential for repeated ulceration, infection, and "supra-pedal" amputation. Myriad conservative and surgical techniques can be used to obtain wound closure. The authors discuss their approach and present operative pearls for their most commonly employed plastic surgical techniques to provide adequate soft tissue coverage of diabetic foot wounds. Emphasis is placed on the techniques necessary to perform these procedures and the surgical thought process involved in closing diabetic foot wounds.
