[PMID: 38734278 DOI: 10.1016/j.ijpharm.2024.124205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 04/30/2024] [Accepted: 05/03/2024] [Indexed: 05/13/2024]
Abstract
The current wound healing process faces numerous challenges such as bacterial infection, inflammation and oxidative stress. However, wound dressings used to promote wound healing, are not well suited to meet the clinical needs. Hyaluronic acid (HA) not only has excellent water absorption and good biocompatibility but facilitates cell function and tissue regeneration. Dopamine, on the other hand, increases the overall viscosity of the hydrogel and possesses antioxidant property. Furthermore, chitosan exhibits outstanding performance in antimicrobial, anti-inflammatory and antioxidant activities. Basic fibroblast growth factor (bFGF) is conducive to cell proliferation and migration, vascular regeneration and wound healing. Hence, we designed an all-in-one hydrogel patch containing dopamine and chitosan framed by hyaluronic acid (HDC) with sprayed gelatin methacryloyl (GelMA) microspheres loaded with bFGF (HDC-bFGF). The hydrogel patch exhibits excellent adhesive, anti-inflammatory, antioxidant and antibacterial properties. In vitro experiments, the HDC-bFGF hydrogel patch not only showed significant inhibitory effect on RAW cell inflammation and Staphylococcus aureus (S. aureus) growth but also effectively scavenged free radicals, in addition to promoting the migration of 3 T3 cells. In the mice acute infected wound model, the HDC-bFGF hydrogel patch adhered to the wound surface greatly accelerated the healing process via its anti-inflammatory and antioxidant activities, bacterial inhibition and pro-vascularization effects. Therefore, the multifunctional HDC-bFGF hydrogel patch holds great promise for clinical application.

Abstract
A best evidence topic in general surgery was written according to a structured protocol, to address the question: in adult patients with perianal abscesses, should postoperative wound packing be undertaken considering the rates of pain experienced, wound healing and abscess recurrence? The literature search identified 159 papers on Ovid, Embase and Medline and 48 on PubMed. These were independently screened, and three articles were included in this review as these offered the best information to answer the question. One was a systematic review without meta-analysis, one was a randomised controlled trial and one was a multicentre observational study. Review of these articles led the authors to conclude that routine postoperative packing of perianal abscesses following incision and drainage is costly, associated with increased pain and confers no protection against recurrence of abscesses or formation of fistulae.

Abstract
Often, patients with rhino-maxillary mucormycosis present with osteomyelitis and necrosis affecting the involved bone. Therefore, curative treatment involves a combination of antifungal therapy and surgical removal of the necrotic bone. In this case report, a 50-year-old female presented with pain in the right side of her face and was diagnosed with rhino-maxillary mucormycosis involving the right maxillary sinus, posterior maxilla, orbital floor, and zygomatic bone. To address the condition, a total maxillectomy of the right maxilla was performed. The post-surgical defect was packed using cotton leno-weave fabric, impregnated with soft paraffin and containing 0.5% chlorhexidine acetate dressing, which was changed every 3rd day. After a six-month follow-up, satisfactory healing was observed. For, rehabilitation, a simple cast partial denture was used.

Abstract
Background Most traditional wound dressings only partially meet the needs of wound healing because of their single function. Patients usually suffer from the increasing cost of treatment and pain resulting from the frequent changing of wound dressings. Herein, we have developed a mutifunctional cryogel to promote bacterial infected wound healing based on a biocompatible polysaccharide. Methods The multifunctional cryogel is made up of a compositive scaffold of chitosan (CS), gelatin (Gel) and tannic acid (TA) and in situ formed silver nanoparticles (Ag NPs). A liver bleeding rat model was used to evaluate the dynamic hemostasis performance of the various cryogels. In order to evaluate the antibacterial properties of the prepared cryogels, gram-positive bacterium Staphylococcus aureus (S. aureus) and gram-negative bacterium Escherichia coli (E. coli) were cultured with the cryogels for 12 h. Meanwhile, S. aureus was introduced to cause bacterial infection in vivo. After treatment for 2 days, the exudates from wound sites were dipped for bacterial colony culture. Subsequently, the anti-inflammatory effect of the various cryogels was evaluated by western blotting and enzyme-linked immunosorbent assay. Finally, full-thickness skin defect models on the back of SD rats were established to assess the wound healing performances of the cryogels. Results Due to its porous structure, the multifunctional cryogel showed fast liver hemostasis. The introduced Ag NPs endowed the cryogel with an antibacterial efficiency of >99.9% against both S. aureus and E. coli. Benefited from the polyphenol groups of TA, the cryogel could inhibit nuclear factor-κB nuclear translocation and down-regulate inflammatory cytokines for an anti-inflammatory effect. Meanwhile, excessive reactive oxygen species could also be scavenged effectively. Despite the presence of Ag NPs, the cryogel did not show cytotoxicity and hemolysis. Moreover, in vivo experiments demonstrated that the biocompatible cryogel displayed effective bacterial disinfection and accelerated wound healing. Conclusions The multifunctional cryogel, with fast hemostasis, antibacterial and anti-inflammation properties and the ability to promote cell proliferation could be widely applied as a wound dressing for bacterial infected wound healing.

Abstract
Thermal energy is an essential and useful resource to humans in modern society. However, a consequence of using heat carelessly is burns. Burn injuries have various causes, such as exposure to flame, radiation, electrical, and chemical sources. In this study, we reviewed the history of burn wound care while focusing on the basic principles of burn management. Through this review, we highlight the need for careful monitoring and customization when treating burn victims at each step of wound care, as their individual needs may differ. We also propose that future research should focus on nanotechnology-based skin grafts, as this is a promising area for further improvement in wound care.

Abstract
We conducted a thirty-four-month retrospective study in the Burns Center from June 2015 to 30 April 2018. A total of 1585 burn wound swabs were taken from 258 admitted patients, of both sex and average age from 2 to 84 years old. Out of the 1585 burn wound swabs, 79.12% were positive for bacterial growth. Gram-negative bacteria were the most common bacteria isolated from burn wound swabs (68.95%), followed by cocci gram positive (28.62%), which were represented mainly by Staphylococcus spp. and Enterococcus spp. species, and then other species such as candida spp. (2.41%). Staphylococcus aureus was found to be the most common isolate (of the 70 Staphylococcus aureus, 52 were methicillino-resistant MRSA) followed by Pseudomonas aeruginosa (n=58; 25.71%), Klebsiella pneumoniae (n=43; 20.15%), Acinetobacter baumannii (n=18; 18.70%), Proteus spp. (n=17; 7.91%), Escherichia coli (n=14; 5,75%), Enterobacter spp. (n=8; 3.22%), Candida spp. (n=6, 2.41%), Stenotrophomonas maltophilia (n=2; 1.73%), and lastly Enterococcus spp. and Citrobacter freundii (n=1; 1.73%). P. aeruginosa was the most frequent Gram-negative bacteria isolated (33.91%). Most of the species isolated were multidrug-resistant (MDR). Knowledge of the bacteria responsible for infectious complications and their antibiotic susceptibilities is a prerequisite for treating burn patients.

Abstract
This study sought to use a newly developed intracellular ATP delivery to enhance incisional wound healing to reduce surgical wound dehiscence and to explore possible mechanism for this effect. Thirty-five adult New Zealand white rabbits were used. Skin incisions were made on the back and closed. ATP-vesicles were mixed with a neutral cream for one side of the wounds while the neutral cream alone was used on the other side of the wounds. Laser speckle contrast imaging (LSCI), biomechanical, histological, and immunohistochemical analyses were performed 7 and 14 days after surgery, and macrophage culture was used to test the enhanced collagen production ability. Among them, 10 were used for wound perfusion study and 25 were used for wound biomechanical and histological/immunohistochemical studies. Wound tissue perfusion was reduced after surgery especially in early days. Wound tissue tensile strength, breaking stress, and elasticity were all much higher in the ATP-vesicle treated group than in the cream treated group at days 7 and 14. The healing was complemented by earlier macrophage accumulation, in situ proliferation, followed by direct collagen production. The results were further confirmed by human macrophage culture. It was concluded that intracellular ATP delivery enhanced healing strength of incisional wounds via multiple mechanisms.

Abstract
BACKGROUND Infection caused by Actinomyces species is a rare cause of head and neck infection in children. This chronic cervicofacial infection can present with localized swelling, abscess formation, sinus drainage and can be complicated by osteomyelitis. METHODS Presented are 2 pediatric cases of secondary actinomycosis in the context of congenital lesions: 1 patient with a previously excised preauricular sinus and another with a persistent sublingual mass. A comprehensive literature search was conducted for reported cases of pediatric actinomycosis in the cervicofacial region. RESULTS Both cases presented were successfully treated with a combination of complete surgical excision of the lesions and prolonged antibiotic therapy. Thirty-four pediatric cases of cervicofacial actinomycosis are reviewed, 2 presented herein, and 32 from the published literature. There was equal gender distribution and the median age was 7.5 years. The most common site for infection was the submandibular area. Four (12%) of cases arose in pre-existing congenital lesions. Most patients were treated with penicillin-based antibiotics for a median duration of 6 months following surgical excision or debridement. CONCLUSIONS Actinomycosis is a rare infection of the cervicofacial region; secondary infections arising from congenital lesions of the head and neck are even more rare. A previously excised pre-auricular sinus and a sublingual dermoid cyst are not previously reported sites of infection. Actinomycosis should be suspected in chronically draining sinuses of the head and neck region and confirmed through anaerobic culture. Osteomyelitis is a potential complication and magnetic resonance (MR) imaging is warranted. Long-term antibiotic therapy with a penicillin-based antibiotic and surgical excision should be considered.

Abstract
OBJECTIVE To evaluate the effect of different dressing methods on the wound healing process after pilonidal sinus surgery. METHODS In this clinical trial, 60 patients undergoing pilonidal sinus surgery were randomly assigned to one of three groups. In the first group, hydrogel or alginate and hydrocolloid compounds were used as a standard occlusive dressing method. A modified dressing method was used for the second group, in which transparent hydrocolloid films were replaced by Vaseline gauze. The third group was treated using gauze swabs soaked in normal saline. The length and depth of the studied wounds were recorded once a week for a month. During dressing changes, patient pain was recorded using an 11-point numeric rating scale. The collected data were analyzed by descriptive and inferential statistical methods. RESULTS There was a significant reduction in wound length after 2 weeks in all three groups (P < .05), and the pain experienced by the first and second groups was significantly lower than the third group. However, the modified method used for the second group was associated with a lower cost. CONCLUSIONS Considering the beneficial results of using modern dressings for wound healing and reducing the severity of associated pain, providers may want to consider using modified wound dressings after pilonidal sinus surgery. Study authors recommend that providers receive training on how to use these products.

Abstract
Wound dressings are important materials for the successful recovery of skin trauma. Traditional wound dressings such as gauzes are not efficient in wound healing. Here we show that silk fibroin, spun from a wild silkworm Antheraea pernyi (A. pernyi) and rich in Arg-Gly-Asp (RGD) sequences, can be developed into a wound dressing after proper modification for improving the cell adhesion to accelerate the skin repair. Specifically, polydopamine (PDA) was coated on an A. pernyi silk fibroin (AF) film to form the PAF film to achieve enhanced cell adhesion and would healing. The PDA coating significantly increased the roughness and hydrophilicity of the AF film and thus its protein absorption capability. Furthermore, the PAF films promoted the adhesion and migration of mesenchymal stem cells (MSCs) in the in vitro wound healing assay. In vivo testing confirmed that wound covered with the PAF film was completely healed with the formation of the new skin and hair within 14 days post trauma. Histological examination indicated that, compared to the AF film and gauze control, the PAF film did not cause significant inflammation in the wound but promoted the epithelialization and well-organized collagen deposition in the dermis. This work indicates that AF films coated with PDA are promising wound dressings for skin tissue repair.

Abstract
AIM Regulated negative pressure-assisted wound therapy is a fundamental, nonpharmaceutical technology for acute and chronically infected wounds, yet bacterial clearance and biofilm buildup remain a challenge for healing. Regulated irrigation combined with negative pressure (RI-NPT) is emerging as an alternative therapeutic strategy for reducing bacterial load. Here, we analyzed RI-NPT hydrokinetics and efficacy of bacterial load reduction in wounds. MATERIALS & METHODS Escherichia coli were loaded with gold nanoparticles, quantified by flame atomic absorption spectroscopy. Computed tomography (CT) imaging tracked bacterial distribution over time in a low-flow rat wound model. Bacterial load was quantified using a novel CT ruler. RESULT Flame atomic absorption spectroscopy showed loading of 1.7 × 103 ± 0.2 gold nanoparticles/cell. CT tracking revealed that while regulated negative pressure-assisted wound therapy reduced bacterial load to a limited extent (5%), RI-NPT significantly increased bacterial outflow and clearance (by 45%). CONCLUSION This nanotechnology-based approach demonstrates that RI-NPT is essential for reducing bacterial load and, thus, for promoting wound healing.

Abstract
Background Surgical wounds healing by secondary intention (SWHSI) are often difficult and costly to treat. There is a dearth of clinical and research information regarding SWHSI. The aim of this survey was to estimate the prevalence of SWHSI and to characterise the aetiology, duration and management of these wounds. Methods Anonymised data were collected from patients with SWHSI receiving treatment in primary, secondary and community settings. Over a two weeks period, data were collected on the patients, their SWHSI, clinical and treatment details. Results Data were collected from 187 patients with a median age of 58.0 (95% CI = 55 to 61) years. The prevalence of SWHSI was 0.41 (95% CI = 0.35 to 0.47) per 1000 population. More patients with SWHSI were being treated in community (109/187, 58.3%) than in secondary (56/187, 29.9%) care settings. Most patients (164/187, 87.7%) had one SWHSI and the median duration of wounds was 28.0 (95% CI = 21 to 35) days. The most common surgical specialities associated with SWHSI were colorectal (80/187, 42.8%), plastics (24/187, 12.8%) and vascular (22/187, 11.8%) surgery. Nearly half of SWHSI were planned to heal by secondary intention (90/187, 48.1%) and 77/187 (41.2%) were wounds that had dehisced. Dressings were the most common single treatment for SWHSI, received by 169/181 (93.4%) patients. Eleven (6.1%) patients were receiving negative pressure wound therapy. Conclusions This survey provides a previously unknown insight into the occurrence, duration, treatment and types of surgery that lead to SWHSI. This information will be of value to patients, health care providers and researchers. Surgical wounds healing by secondary intention (SWHSI) are a common problem with a prevalence of 0.41 per 1000 population. Approximately 50% of SWHSI are planned. The surgical specialities most commonly associated with SWHSI were colorectal, plastics and vascular surgery. The median duration of SWHSI at the time of the survey was 28.0 (95% CI = 21 to 35) days. Negative pressure wound therapy was used in 6.1% of SWHSI at the time of this survey.

Abstract
Wound dressings play an important role in a patient's recovery from health problems, as unattended wounds could lead to serious complications such as infections or, ultimately, even death. Therefore, wound dressings since ancient times have been continuously developed, starting from simple dressings from natural materials for covering wounds to modern dressings with functionalized materials to aid in the wound healing process and enhance tissue repair. However, understanding the nature of a wound and the subsequent healing process is vital information upon which dressings can be tailored to ensure a patient's recovery. To date, much progress has been made through the use of nanomedicine in wound healing due to the ability of such materials to mimic the natural dimensions of tissue. This review provides an overview of recent studies on the physiology of wound healing and various wound dressing materials made of nanofibers fabricated using the electrospinning technique.

Abstract
Management of chronic wounds in the outpatient setting is quite challenging. The extensive co-morbid medical problems of the chronically ill patient along with the complexities of the wound bed and its biochemical environment has led to a plethora of patients with poor wound healing. This ever increasing population is a challenge for the wound care practitioner and cost to the health care system and patient. Increased wound chronicity has promulgated the use of advanced wound care products, including Living Skin Substitutes (LSS), in an attempt to obtain wound closure, and ultimately both physiological and functional healing.(1-3) In the outpatient setting, it is evident that the efficacy of the LSS varies widely depending on the patient type with some patients responding quite favorably while others who do not achieve healing despite repeated applications of LSS. This case series demonstrates that a systematic method of wound bed preparation prior to the application of LSS improved healing outcomes. The entire wound bed preparation protocol included autolytic, non-selective, and sharp-selective debridement, if deemed appropriate, followed by the weekly application of a pure native collagen. The wound bed preparation protocol was completed prior to LSS application. This case series presents evidence supporting the application of a 100% native collagen dressing to wound bed prior to the final step of LSS utilization.

Abstract
The objective of this study was to assess acceptability (based on pain at removal), efficacy and tolerance of an absorbent and cohesive rope(UrgoClean Rope, Laboratoires Urgo) in the local management of deep cavity wounds. This study was a prospective, multicentre (13), non comparative clinical study. Patients presenting with an acute or chronic non-infected cavity wound were followed up for four weeks and assessed weekly with a physical examination, in addition to volumetric,planimetric and photographic evaluations. Pain at removal was the primary criterion, assessed on a Visual Analogic Scale. The percentage of the wound surface area reduction and volumetric reduction were considered as secondary efficacy criteria. Forty three patients were included in this study. After one week of treatment dressing removal was painless and continued to be so throughout the period of the trial(four weeks). Median surface area at baseline was 7.74 cm2 and was reduced by 54.5% at week 4 (relative area reduction). Median wound volumetric value was noted 12 ml at baseline and was reduced by 72.7% by the end of treatment. The cohesiveness of the new rope was considered very good by health professionals. No residue was observed on the wound bed during the dressing change with the new rope. There were no adverse events related to the tested rope, during this trial.Pain-free removal associated with good efficacy and tolerance were observed with this new cohesive rope in the healing process of deep cavity wounds and could represent a therapeutic alternative to the usual ropes used in such indications.

Abstract
The authors present a case of a surgical wound that was inappropriately packed to the extent that a significant and major deterioration occurred in the expected healing by secondary intention. This is intended to alert surgeons to the fact that careful supervision is required of such seemingly simple and straightforward tasks as the topical treatment of open wounds by inexperienced caregivers.

Abstract
The variety of wound types has resulted in a wide range of wound dressings with new products frequently introduced to target different aspects of the wound healing process. The ideal dressing should achieve rapid healing at reasonable cost with minimal inconvenience to the patient. This article offers a review of the common wound management dressings and emerging technologies for achieving improved wound healing. It also reviews many of the dressings and novel polymers used for the delivery of drugs to acute, chronic and other types of wound. These include hydrocolloids, alginates, hydrogels, polyurethane, collagen, chitosan, pectin and hyaluronic acid. There is also a brief section on the use of biological polymers as tissue engineered scaffolds and skin grafts. Pharmacological agents such as antibiotics, vitamins, minerals, growth factors and other wound healing accelerators that take active part in the healing process are discussed. Direct delivery of these agents to the wound site is desirable, particularly when systemic delivery could cause organ damage due to toxicological concerns associated with the preferred agents. This review concerns the requirement for formulations with improved properties for effective and accurate delivery of the required therapeutic agents. General formulation approaches towards achieving optimum physical properties and controlled delivery characteristics for an active wound healing dosage form are also considered briefly.
