A wound refers to the epithelial loss, accompanied by loss of muscle fibers collagen, nerves and bone instigated by surgery, trauma, frictions or by heat. Process of wound healing is a compounded activity of recovering the functional integrity of the damaged tissues. This process is mediated by various cytokines and growth factors usually liberated at the wound site. A plethora of herbal and synthetic drugs, as well as photodynamic therapy, is available to facilitate the process of wound healing. Generally, the systems used for the management of wounds tend to act through covering the ruptured site, reduce pain, inflammation, and prevent the invasion and growth of microorganisms. The available systems are, though, enough to meet these requirements, but the involvement of nanotechnology can ameliorate the performance of these protective coverings. In recent years, nano-based formulations have gained immense popularity among researchers for the wound healing process due to the enhanced benefits they offer over the conventional preparations. Hereupon, this review aims to cover the entire roadmap of wound healing, beginning from the molecular factors involved in the process, the various synthetic and herbal agents, and combination therapy available for the treatment and the current nano-based systems available for delivery through the topical route for wound healing.

Despite the evolution in modern surgery and in pharmaceutical industry, purulent pathology of the hand is occupying a leading position for many years among all diseases with which patients are admitted to hospitals. Over the years, medical care for such patients has been improving. A high social and economic significance of this problem makes surgeons to continue searches of new directions not only in surgical techniques, but also in postoperative wound management to improve outcomes in patients with purulent diseases of the hand.The purpose of this work is to assess results of care of patients with purulent finger and hand diseases treated with laser light necrectomy and photodynamic therapy. A comparative analysis of wound process dynamics and treatment outcomes in 198 patients with hand purulent diseases who had been admitted to Moscow City Hospital No. 4 was made by the authors. All patients were divided into four groups depending on the curative modality. In Group 1 (n = 53), a wound was sutured after surgery, and a drainage-lavage system (DLS) was installed; in Group 2 (n = 50), a wound was not sutured because of contraindications to suturing; in Group 3 (n = 46), patients had laser necrectomy after which a wound was sutured and DLS was installed; in Group 4 (n = 49), a wound was not sutured because of contraindications like in Group 2, but it was treated with antiseptic dressings and photodynamic therapy at an early postoperative period. Various aspects of the effectiveness of laser techniques have been analyzed: dynamics of wound healing, changes in wound defect size, level of pain syndrome assessed by VAS, changes in clinical blood tests, changes in wound exudate cytological picture as well as changes in wound microflora. Acceleration of wound healing was noted in all patients who were treated with laser light what, consequently, shortened their inpatient stay. Laser light also changed cytological and microbiological patterns of wound exudate, as evidenced by the decrease of wound detritus and by the decrease of microbial content in the wound. In patients, who were treated with laser light, less pain syndrome was registered immediately after laser technique application.The obtained findings demonstrate a positive effect of laser necrectomy with DLS at wound process as well. Photodynamic therapy significantly improved results in patients with open wound management on the hand and fingers. Laser techniques have good perspectives in purulent surgery of the hand.

Background: Antibiotic resistance and impaired wound healing are major concerns in S. aureus superficial skin infections, and new therapies are needed. Antimicrobial photodynamic therapy (aPDT) is a new therapeutic approach for infections, but it also improves healing in many wound models.Objective: To compare the antimicrobial activity and the effects on wound healing of aPDT based on Methylene Blue (MB-aPDT) with mupirocin treatment, either alone or in combination, in superficial skin wounds of S. aureus-infected mice. Additionally, to evaluate the clinical, microbiological, and cosmetic effects on wound healing.Materials and Methods: A superficial skin infection model of S. aureus was established in SKH-1 mice. Infected wounds were treated with MB-aPDT, MB-aPDT with a daily topical mupirocin or only with mupirocin. No treatment was carried out in control animals. Daily clinical and microbiological examinations were performed until complete clinical wound healing. Histopathological studies and statistical analysis were performed at the end of the study.Results: MB-aPDT treatment induced the best wound healing compared to mupirocin alone or to mupirocin plus MB-aPDT. Superficial contraction at 24 h and a greater reduction in size at 48 h, quicker detachment of the crust, less scaling, and absence of scars were observed. Histopathological studies correlated with clinical and gross findings. By contrast, mupirocin showed the highest logaritmic reduction of S. aureus.Conclusions: MB-aPDT and mupirocin treatments are effective in a murine superficial skin infection model of S. aureus. One session of MB-aPDT was the best option for clinical wound healing and cosmetic results. The addition of mupirocin to MB-aPDT treatment improved antimicrobial activity; however, it did not enhance wound healing. No synergistic antibacterial effects were detected.
