Sprayable biogenic Ag-collagen nanocomposites with potent antibacterial and antibiofilm activity for Acinetobacter baumannii infected wound healing under hyperglycemic condition

Owing to their susceptibility to infection by drug-resistant bacteria, refractory wounds pose a formidable risk to the well-being of patients with diabetes and other immune-compromised conditions, and their management poses significant economic distress to the healthcare system, particularly in low and middle-income countries. Therefore, deployable interventions for rapid and effective management of such wounds are needed. In the present study, we report the processing of sprayable biogenic Ag-collagen nanocomposites (Ag-Col NCs) with cogent antibacterial and healing activity in Acinetobacter baumannii infected wounds under hyperglycemic conditions. Silver nanoparticles (Ag NPs) has been synthesized by using the plant extract of Urginea indica (U. indica), which was further used for the processing of Ag-Col NCs. Synthesized NCs were found to have notable broad spectrum antibacterial activity against clinically significant strains (Acinetobacter baumannii, Staphylococcus aureus and Methicillin-resistant Staphylococcus aureus) and appreciable biocompatibility towards RAW 264.7 and 3 T3 mouse fibroblast cell lines. The sprayable NC system was found to promote the wound healing activity in mouse model (Balb/c) not only in normal but also in hyperglycemic conditions. Our experimental findings suggest the potential of the Ag-Col NC spray in chronic wound management and an exploitable option in both clinical and personalized settings.

Pecto-intercostal Fascial Plane Block: A Novel Technique for Analgesia in Patients with Sternal Dehiscence.

Sternal wound complications following sternotomy need a multidisciplinary approach in high-risk postoperative cardiac surgical patients. Poorly controlled pain during surgical management of such wounds increases cardiovascular stress and respiratory complications. Multimodal analgesia including intravenous opioids, non-opioid analgesics, and regional anesthesia techniques, like central neuraxial blocks and fascial plane blocks, have been described. Pecto-intercostal fascial plane block (PIFB), a novel technique, has been effectively used in patients undergoing cardiac surgery. Under ultrasound (US) guidance PIFB is performed with the aim of depositing local anesthetic between two superficial muscles, namely the pectoralis major muscle and the external intercostal muscle. The authors report a series of five cases where US-guided bilateral PIFB was used in patients undergoing sternal wound debridement. Patients had excellent analgesia intraoperatively as well as postoperatively for 24 hours with minimal requirement of supplemental analgesia. None of the patients experienced complications due to PIFB administration. The authors concluded that bilateral PIFB can be effectively used as an adjunct to multimodal analgesia with general anesthesia and as a sole anesthesia technique in selected cases of sternal wound debridement.

Local personalised treatment of long-term non-healing wounds

Introduction. A significant number of nosologies can result in long-term non-healing wounds that mostly have similar principles of local treatment. However, positive clinical outcomes are not always obtained in the management of such wounds. The authors have developed a personalized technology for local treatment of chronic wounds depending on their etiology. Aim. Was to investigate the effectiveness of the proposed methods and personalized approaches for local treatment of long-term nonhealing wounds. Materials and methods. Innovative methods of cleaning and stimulating regeneration of non-healing wounds have been developed in the study; their effectiveness was tested in 3 blocks of the study. The first block of the study included patients with long-term non-healing wounds of venous etiology, the second and third blocks included patients with long-term non-healing arterial and neurotrophic wounds, respectively. Each block involved two series of tests studying the developed methods of cryodestruction and stimulation of regeneration, respectively. In the 1st block, the 3rd series of tests was additionally conducted; it included patients with wounds larger than 20 cm2 in size. Results. The developed methods of cryodestruction accelerate the course of phase I of the wound process by 12% in patients with longterm non-healing wounds of venous etiology, by 27% in patients with critical ischemia of the lower extremities, by 70% in patients with neurotrophic etiology (p ≥ 0.05). The use of the proposed methods of stimulating regeneration significantly reduced the average area of wounds in the study blocks. The main components of treatment stimulating regeneration in long-term non-healing wounds have been identified considering wound etiology. Conclusion. The use of the developed algorithm for local personalized treatment of long-term non-healing wounds considering underlying disorders contributes to an earlier cleaning of the wound surface, elimination of inflammation and an increased activity of regeneration processes when compared with conventional approaches.

Association of Systemic or Intravitreal Antivascular Endothelial Growth Factor (Anti-VEGF) and Impaired Wound Healing in Pediatric Patients: Collagen to the Rescue.

Bevacizumab is a humanized monoclonal antibody to vascular endothelial growth factor (VEGF) that has been used as a systemic chemotherapy treatment of various malignancies in adults since 2000. It has been used for pediatric patients over the last decade. In addition, bevacizumab is used for neonatal intravitreal administration for retinopathy of prematurity, a major complication of preterm birth, characterized by incomplete and abnormal vascularization of the retina that can lead to retinal detachment and blindness without treatment. The objective of this multiple case series is to report impaired wound healing seen in 3 adolescents and 1 premature neonate receiving bevacizumab and to propose collagen-based dermal template as a choice for the management of such wounds. The 3 adolescents were undergoing treatment of malignancies and developed wound healing complication within weeks of receiving anti-VEGF. The premature neonate experienced an extravasation and had a slow wound healing trajectory after receiving intravitreal administration of bevacizumab for retinopathy of prematurity. All wounds achieved closure following topical treatment with a collagen dermal template. Use of bevacizumab is increasing in the pediatric population. Clinicians should be aware of compromised wound healing and higher likelihood of wound dehiscence after bevacizumab administration. We recommend waiting for at least 4 to 6 weeks between anti-VEGF administration (either systemic or vitreous) and elective surgical procedures, consistent with adult literature recommendations. If patient has an existing wound, we assert that bevacizumab should not be administered until that wound is healed. If wound healing is stalled, we recommend dermal template as a safe and effective accelerator of wound healing.

A Comparative Study between Indigenous Low Cost Negative Pressure Wound Therapy with Added Local Oxygen versus Conventional Negative Pressure Wound Therapy.

Introduction:The incidence of compound fractures and severe soft tissue loss has increased manifolds due to high speed traffics. Negative Pressure Wound Therapy (NPWT) is a treatment modality for managing soft tissue aspect of such injuries. It reduces the need of flap coverage. However, many patients from developing countries cannot afford a conventional NPWT. We developed an indigenous low cost NPWT for our patients and supplemented it with Topical Pressurised Oxygen Therapy (TPOT). We conducted this study to compare its treatment outcome with the use of conventional NPWT.Materials and Methods:The study was conducted from 2018 to 2020 at a tertiary care teaching hospital. A total of 86 patients were treated with NPWT and their results were assessed for various parameters like reduction in wound size, discharge, infection, etc. We included patients with acute traumatic wounds as well as chronic infected wounds, and placed them in three treatment groups to receive either conventional NPWT, Indigenous NPWT and lastly NPWT with supplement TPOT.Results:We observed a significant reduction of wound size, discharge and infection control in all three groups. The efficacy of indigenous NPWT is at par with conventional NPWT. Only six patients who had several comorbidities required flap coverage while in another four patients we could not achieve desired result due to technical limitations.Conclusion:Indigenous NPWT with added TPOT is a very potent and cost effective method to control infection and rapid management of severe trauma seen in orthopaedic practice. It also decreases the dependency on plastic surgeons for management of such wounds.

Appropriate antibiotics in dog bite injuries: an audit study

Background: Dog bite injuries are a common presentation to Accident and Emergency. In the United Kingdom ~250,000 people attend emergency units each year as a result of dog wounds. Currently, there is a lack of consistency in the approach and management of such wounds across plastic surgery units in the United Kingdom. Method: A retrospective review of medical record of patients who were admitted under the care of the Plastic Surgery Department at University Hospital North Midlands NHS Foundation Trust with dog-bite wounds between January and December 2018. Results: Of the 69 patients that were included in the study, 14 (20%) of them had been prescribed antibiotics that were ineffective and against antimicrobial guidelines. Following liaison with the antimicrobial governance team and input from NICE guidelines, the trust’s MicroGuide Antibiotic Prescribing Guidelines App was updated. A reaudit from November 2019 to February 2020 showed that there was 100% compliance with guidance. Conclusion: Updating the University Hospital of North Midlands NHS Trust’s MicroGuide antibiotic prescribing guidelines for the treatment of dog-bite injuries resulted in 100% of patients being treated with the correct antibiotic. Given the polymicrobial nature of animal-bite wounds, and the high levels of resistance demonstrated by organisms commonly found in such injuries, this increased compliance with guidelines helps minimize patient suffering, morbidity, length of stay, and disability, while reducing costs incurred. The intervention should be implemented within other units within the United Kingdom who similarly lack clear, detailed guidelines, in order to maximize treatment continuity and patient outcomes nationwide.

Evaluation of Effect of Katupila Arka in Post-Operative Fistulotomy wound Management: A Case Report

Introduction: Securinega leucopyrus Muell. is known as Humari in India, Katupila in Sri Lanka and Spinous fluggea in English. It is a desert climatic plant used topically in paste form for healing of acute, chronic and non-healing wounds as a folklore practice in Sri Lanka. The aim of this study is to evaluate the role of Katupila Arka in the management of post-operative wound of fistulotomy. Methodology: It is a case report of a 42 years old male patient who presented with the chief complains of swelling around the anal region associated with pain and pus discharge. On examination, it was diagnosed as subcutaneous low-level fistula. Hence, he was treated by fistulotomy under local anesthesia. The wound was dressed with Katupila Arka twice daily for 1 week and once daily for a period of 14 days. Result: Complete healing of the post-operative wound was observed in 3 weeks period without any complications. Discussion: Post-operative fistulotomy wound is a contaminated wound and is more prone to get further contamination by feces, which may lead to secondary infections or delayed wound healing. So, management of such wounds is a challenging task. In the present case, Katupila Arka has shown promising results in successful management of the post fistulotomy wound with ease and devoid of any complications. Further clinical study is needed to evaluate the effectiveness in larger sample. How to cite this article:Sweta KM, AJ Shetty, Ramesh PB.

Chronic wounds: the challenges of appropriate management.

The immense burden imposed by chronic wounds-those persisting over 6 weeks despite active intervention-on patients and health services is well recognised. There are various reasons for why a wound fails to progress towards closure, and clinicians must investigate the underlying cause of wound chronicity, as this information guides the management of such wounds. The TIME framework (T=tissue; I=infection/inflammation; M=moisture balance; E=wound edges) is a useful tool for practitioners to systematically undertake wound assessment and product selection. This article discusses chronic wound management based on the TIME framework, examining the aspects to be considered when managing chronic wounds. It also describes the process of dressing selection for overcoming the various barriers to wound healing, specifically discussing the AQUACEL family of dressings.

Nano crystalline silver: a breakthrough in treating diabetic foot ulcers

India harbours world’s largest population of diabetic patients thus earning an infamous designation of ‘diabetic capital of the world’. Apart from various metabolic aberrations that are bound to happen in a patient with uncontrolled hyperglycemia, foot ulcers are one of the serious complications that may become limb and life threatening, if not addressed properly. Surgical debridement along with appropriate antibiotics, remain as the mainstay of management of such wounds. Conventional dressing methods involving povidone-iodine and other antiseptic agents have offered limited scope of effective wound healing owing to their inherent toxicity towards fibroblasts. In the present scenario where a large chunk of population crosses over to the list of newly diagnosed diabetics every year, nano crystalline silver has come as a breakthrough in effective management and early healing of diabetic foot ulcers through its effective antimicrobial action and limited toxicity for the host tissue.

A Meta-Analysis of the Outcomes of Split-Thickness Skin Graft on Diabetic Leg and Foot Ulcers.

Diabetic lower limb ulcers are a serious complication to diabetes that could lead to amputation and death. Split-thickness skin graft (STSG) has been proposed by some authors to treat noninfected diabetic wounds, mainly those found in the leg and on the dorsum of the foot. No quantitative evidence synthesis over this technique has been reported in the literature. The study is a meta-analysis on the effectiveness of STSG in treating diabetic leg and foot ulcers. Electronic databases were searched from inception. No limitation was imposed on study design. Eleven studies comprising 757 patients with 759 foot/leg ulcers were included. After a mean period of 2 years, 85.5% (95% confidence interval [CI] = 0.766-0.925) of ulcers were healed over a mean time of 5.35 ± 2.25 weeks, with a recurrence rate of 4.2% (95% CI = 0.009-0.096), an infection rate of 4.4% (95% CI = 0.013-0.092), and a regrafting rate of 12.1% (95% CI = 0.053-0.212). Infection was the only reported donor site morbidity with a frequency of 1.74% (95% CI = 0.001-0.048). These weighted values are found to be noticeably superior to those reported in the literature following standard conventional care. The results of the review make STSG the ideal method to treat noninfected recurrent or recalcitrant ulcers of the leg and dorsal foot. Furthermore, the authors argue that STSG should be used more frequently in the management of such wounds. The findings should encourage future prospective investigations.

The reality of routine practice: a pooled data analysis on chronic wounds treated with TLC-NOSF wound dressings.

A number of randomised controlled trials (RCT) have compared control groups with TLC-NOSF dressings (UrgoStart) on chronic wounds. Our aim was to determine whether the clinical trials' results translate into routine management of such wounds, by pooling the data from real-life observational studies. Observational studies, conducted in France and Germany, evaluating current practices in patients suffering from non-selected chronic wounds treated with a TLC-NOSF dressing were identified. Demographic data, baseline description of wounds and description of their evolution during treatment were extracted and combined. We used two main indicators of clinical outcomes to measure the impact of the TLC-NOSF dressing on this population: time to wound closure and time to 50% reduction of the Pressure Ulcer Scale for Healing (PUSH) score. In total, data from 10,220 patients were included, with 7903 leg ulcers (LUs), 1306 diabetic foot ulcers (DFUs) and 1011 pressure ulcers (PUs). The overall closure rate was 30.8 % [95 % confidence interval (CI): 29.9-31.7 %]. While the country, patient age, and number of wounds were identified as independent prognosis factors of healing, the most significant were wound duration and baseline area. The delay in initiating TLC-NOSF dressings treatment was also found to be significant. Overall the average time to complete closure was 112.5 days [95%CI: 105.8-119.3] for LUs, 98.1 days [95 %CI: 88.8-107.5] for DFUs and 119.5 days [95%CI: 94.6-144.3] for PUs. Based on a subgroup analysis of the French cohort, time to closure is substantially shorter for wounds treated with the TLC-NOSF dressing as a first-line intervention compared with those where it has been prescribed as a second-line intervention. Compared with available data on time to complete closure of chronic wounds managed by 'standard' care, the data from this pooled data analysis showed healing time is reduced, which is consistent with the results of RCTs on TLC-NOSF. That these data are in agreement with those from the RCTs is testimony to their generalisability and important for routine practice. This indicates that using TLC-NOSF dressings in routine wound management can reduce the healing time of LUs, DFUs and PUs. These data also suggest that the earlier the decision to use this dressing, the shorter the time to closure, whatever the severity and the nature of these chronic wounds.

Facial dog attack injuries.

The exposed position of the face makes it vulnerable to dog bite injuries. This fact combined with the short stature of children makes them a high-risk group for such attacks. In contrast to wounds inflicted by assaults and accidents, dog bite wounds are deep puncture type wounds compounded by the presence of pathologic bacteria from the saliva of the attacking dog. This, combined with the presence of crushed, devitalized tissue makes these wounds highly susceptible to infection. Key to successful management of such wounds are meticulous cleansing of the wound, careful debridement, primary repair, appropriate antibiotic therapy, and rabies and tetanus immunization where indicated. This review presents an overview of the epidemiology, presentation, management of such emergencies, and the recent advances in the care of such patients.

Role of stem cells in the management of chronic wounds

Chronic wounds continue to be a major challenge for the medical profession, and plastic surgeons are frequently called in to help in the management of such wounds. Apart from the obvious morbidity to the patient, these problem wounds can be a major drain on the already scarce hospital resources. Sometimes, these chronic wounds can be more taxing than the underlying disease itself. Although many newer methods are available to handle such situations, the role of stem cells in the management of such wounds is an exciting area that needs to be explored further. A review of literature has been done regarding the role of stem cells in the management of chronic wounds. The abnormal pathology in such wounds is discussed and the possible role of stem cells for optimal healing in such cases would be detailed.

Symptoms Associated with Malignant Wounds: A Prospective Case Series

A significant proportion of cancer patients develop malignant wounds. Malignant wounds are generally nonhealable and are managed with palliative methods. Palliative wound care encompasses the pain and symptom management of such wounds. Sixty-seven of 472 cancer patients from a prospective sequential case series of palliative medicine consultations demonstrated malignant wounds at the time of referral and were studied to determine the most common symptoms and anatomic sites associated with malignant wounds. Data were collected from patients' own reports of up to three wound-related symptoms. Overall, 67.7% of malignant wounds were associated with at least one of the following eight symptoms: pain, mass effect, esthetic distress, exudation, odor, pruritus, bleeding, and crusting; 21.9% of wounds were associated with two or more symptoms; and 11.5% of wounds were associated with three symptoms. The symptom point prevalence was 31.3% for pain, 23.9% for mass effect, 19.4% for esthetic distress, 17.9% for exudation, 11.9% for odor, 6% for pruritus, 6% for bleeding, and 1.5% for crusting. Breast cancer patients had the highest prevalence of malignant wounds (47.1%). The anterior chest wall and breast was the site of 31.2% of wounds. The perineum and genitalia presented with the highest ratio of symptoms per wound (2.2). The results of this study reflect that malignant wounds are associated with a significant symptomatic burden, and reinforces the need for thorough clinical assessment and evaluation of symptoms. Further research is required to define the optimal methods of pain and symptom management for malignant wounds.

Non-surgical and drug treatments

Despite great strides in technological innovations and the emergence of a wide range of treatments for wounds, non-healing wounds continue to perplex and challenge doctors. Various non-surgical approaches have been...

Regeneration of full layer necrosis of the skull following high voltage electrical injury

Scalp and skull necrosis often follow high voltage electrical injury to the head. Classically reconstruction of the scalp and skull is performed after sequestration of the necrotic bone. The relatively frequent complication of epidural infection, however, detracts from this approach. As an alternative we have attempted to induce regeneration of devitalized bone by covering it with a vascular tissue flap. A typical patient is described in this report with results which indicate that at least partial regeneration of the necrotic tissue can occur, thus one-stage management of such wounds is possible.

Severe shear injury to the buttocks and perineum.

1. Shear Injuries to the perineum and buttocks are thought to constitute another serious result of vehicular accidents, and two illustrative cases are described. 2. In view of the severe trauma which usually precipitates these lacerations, multiple other injuries are often found which may demand urgent attention. 3. Despite the presence of an intact rectum, fæcal diversion is considered to be mandatory In the management of such wounds to assist in nursing, and to reduce the risk of continuing severe infection. 4. Timely skin grafting helps greatly in expediting the healing of the enormous soft tissue defects, the skin being best applied to the open wound. 5. Both illustrative cases had points of additional interest In so far as one patient developed recurrent thyrotoxicosis after injury (thus providing an unusual cause of persistent pyrexia), while the other sustained multiple injuries and developed high-output renal failure.
