Abstract Background Wound healing is a complex and dynamic process. Healing of acute and chronic wounds can be impaired by patient factors (that is, comorbidities) and/or wound factors (that is, infection). Regenerative medicine products, such as autologous/homologous platelet-rich plasma gel, may speed up the healing process. Autologous/homologous platelet-rich plasma is an advanced wound therapy used for hard-to-heal acute and chronic wounds. The cytokines and growth factors contained in platelet-rich plasma play a crucial role in the healing process. Case presentation A 61-year-old Caucasian male patient, suffering from mental retardation following meningitis, with a transplanted kidney due to prior renal impairment, and under immunosuppressant therapy, was submitted to aneurysmectomy of his proximal left forearm arteriovenous fistula. A few days later, the patient came to our attention with substantial blood loss from the surgical site. The wound presented no signs of healing, and after fistula reparation and considering persistent infection of the surgical site (by methicillin-resistant Staphylococcus aureus), surgeons decided for second-intention healing. To favor healing, 10 mL homologous platelet concentrate gel was sequentially applied. After each application, wound was covered with nonadherent antiseptic dressing. After only seven applications of homologous platelet concentrate gel, wound completely recovered and no amputation was necessary. Conclusions Topical application of homologous platelet-rich plasma gel in healing wound shows beneficial results in wound size reduction and induces granulation tissue formation. Platelet-rich plasma could be a safe and cost-effective treatment for managing the cutaneous wound healing process to shorten the recovery period and thereby improve patient quality of life.

Healing Wound

Chronic wounds occur when one wound healing process or a sequence of wound healing events are affected resulting in slow healing of the wound thereby placing the patient in deep pain. Various diseases and conditions can delay the process of wound healing. Wound healing can be classified into four main stages: hemostasis, inflammation, remodeling, and scar tissue formation with each phase overlapping one another. The skin is the largest organ in the body. It protects the entire external surface of the human body and is the primary site of interaction with the outside environment. There is therefore a need to fabricate an ideal dressing through scientific research and investigations. Hydrogels are a three-dimensional network of hydrophilic polymers that can swell in water and absorb copious amounts of water while maintaining their structure because of their chemical or physical crosslinking of individual polymer chains. A hydrogel must be composed of at least 10% water. Hydrogels possess the flexibility and water percentage which is remarkably like tissues. They are biocompatible and biodegradable which makes them ideal for dermal wound healing.

The wounds which fail to progress through a timely sequence of repair or that proceed through the wound healing process without restoring anatomic and functional integrity are referred as chronic non-healing wounds. This study was conducted on a 50-year old male patient with a painful non-healing ulcer on the medial malleolus of the left lower limb caused by the use of hot water bag during harsh winter in Srinagar. The size of the wound was 2x2 cm on assessing the wound profile. The wound was treated with the application of an ointment made with the combination of powder of Astragalus sarcocolla and Honey in equal amounts. The ointment was applied twice a day on the wound for 20 days. After 7 days of daily application, there was a considerable reduction in the size of wound and significant improvement in other symptoms like pain and tenderness. The ulcer was completely healed in a time period of 21 days. The present case reports that, the ointment prepared with Astragalus sarcocolla and Honey is a cost effective treatment for chronic non-healing wound.

Platelet-rich fibrin (PRF) is a recent platelet-based biomaterial, poised as an innovative regenerative strategy for the treatment of wounds from different etiologies. PRF is defined as a biodegradable scaffold containing elevated amounts of platelets and leukocytes having the capability to release high concentrations of bioactive structural proteins and acting as a temporal release healing hemoderivative. This study aimed to evaluate the performance of canine-origin PRF, obtained from blood of screened donors, as a regenerative biomaterial suitable for the treatment of critical wounds in felines. Four short-hair felines with naturally occurring wounds were enrolled in this study. Three of the wounds were considered infected. Each PRF treatment was the result of the grafting of newly produced PRFs at the recipient area. The PRF treatment was initially performed two to three times per week, followed by single weekly treatments. The study was finalized when complete wound closure was achieved. No topical antimicrobial/antiseptic treatment was applied. The present research demonstrated that xenogenic PRFs significantly induced healthy vascularized granulation tissue in lesions with soft tissue deficit, also prompting the epithelization at the injured site. No rejection, necrosis, or infection signs were recorded. Additionally, PRF-therapy was revealed to be a biological cost-effective treatment, accelerating the wound healing process.

Treatment Of Wounds

The treatment of wounds is one challenging biomedical field due to delayed wound healing common in chronic wounds. Several factors delay wound healing, including microbial infections, malnutrition, underlying physiological conditions, etc. Most of the currently used wound dressing materials suffer from poor antimicrobial properties, poor biodegradability and biocompatibility, and weak mechanical performance. Plant extracts, such as Aloe vera, have attracted significant attention in wound management because of their interesting biological properties. Aloe vera is composed of essential constituents beneficial for the wound healing process, such as amino acids, vitamins C and E, and zinc. Aloe vera influences numerous factors that are involved in wound healing and stimulates accelerated healing. This review reports the therapeutic outcomes of aloe vera extract-loaded polymer-based scaffolds in wound management.

: Chronic wounds remain a significant public problem and the development of wound treatments has been a research focus for the past few decades. Despite advances in the products derived from endogenous substances involved in a wound healing process (e.g. growth factors, stem cells, and extracellular matrix), effective and safe wound therapeutics are still limited. There is an unmet need to develop new therapeutics. Various new pathways and targets have been identified and could become a molecular target in designing novel wound agents. Importantly, many existing drugs that target these newly identified pathways could be repositioned for wound therapy, which will facilitate fast translation of research findings to clinical applications. This review discusses the newly identified pathways/targets and their potential uses in the development of wound therapeutics. Some herbs and amphibian skins have been traditionally used for wound repairs and their active ingredients have been found to act in these new pathways. Hence, screening these natural products for novel wound therapeutics remains a viable approach. The outcomes of wound care using natural wound therapeutics could be improved if we can better understand their cellular and molecular mechanisms and fabricate them in appropriate formulations, such as using novel wound dressings and nano-engineered materials. Therefore, we also provide an update on the advances in the wound therapeutics from natural sources. Overall, this review offers new insights into novel wound therapeutics.

Despite the advances that have been achieved in developing wound dressings to date, wound healing still remains a challenge in the healthcare system. None of the wound dressings currently used clinically can mimic all the properties of normal and healthy skin. Electrospinning has gained remarkable attention in wound healing applications because of its excellent ability to form nanostructures similar to natural extracellular matrix (ECM). Electrospun dressing accelerates the wound healing process by transferring drugs or active agents to the wound site sooner. This review provides a concise overview of the recent developments in bioactive electrospun dressings, which are effective in treating acute and chronic wounds and can successfully heal the wound. We also discuss bioactive agents used to incorporate electrospun wound dressings to improve their therapeutic potential in wound healing. In addition, here we present commercial dressings loaded with bioactive agents with a comparison between their features and capabilities. Furthermore, we discuss challenges and promises and offer suggestions for future research on bioactive agent-loaded nanofiber membranes to guide future researchers in designing more effective dressing for wound healing and skin regeneration.

Chronic wounds are a major health problem that cause millions of dollars in expenses every year. Among all the treatments used, active wound treatments such as enzymatic treatments represent a cheaper and specific option with a fast growth category in the market. In particular, bacterial and plant proteases have been employed due to their homology to human proteases, which drive the normal wound healing process. However, the use of these proteases has demonstrated results with low reproducibility. Therefore, alternative sources of proteases such as snake venom have been proposed. Here, we performed a functional mining of proteases from rattlesnakes (Crotalus ornatus, C. molossus nigrescens, C. scutulatus, and C. atrox) due to their high protease predominance and similarity to native proteases. To characterize Crotalus spp. Proteases, we performed different protease assays to measure and confirm the presence of metalloproteases and serine proteases, such as the universal protease assay and zymography, using several substrates such as gelatin, casein, hemoglobin, L-TAME, fibrinogen, and fibrin. We found that all our venom extracts degraded casein, gelatin, L-TAME, fibrinogen, and fibrin, but not hemoglobin. Crotalus ornatus and C. m. nigrescens extracts were the most proteolytic venoms among the samples. Particularly, C. ornatus predominantly possessed low molecular weight proteases (P-I metalloproteases). Our results demonstrated the presence of metalloproteases capable of degrading gelatin (a collagen derivative) and fibrin clots, whereas serine proteases were capable of degrading fibrinogen-generating fibrin clots, mimicking thrombin activity. Moreover, we demonstrated that Crotalus spp. are a valuable source of proteases that can aid chronic wound-healing treatments.
