Wound Healing Time Research Articles

Tetrahedral framework nucleic acids/hyaluronic acid-methacrylic anhydride hybrid hydrogel with antimicrobial and anti-inflammatory properties for infected wound healing.

Bacterial resistance and excessive inflammation are common issues that hinder wound healing. Antimicrobial peptides (AMPs) offer a promising and versatile antibacterial option compared to traditional antibiotics, with additional anti-inflammatory properties. However, the applications of AMPs are limited by their antimicrobial effects and stability against bacterial degradation. TFNAs are regarded as a promising drug delivery platform that could enhance the antibacterial properties and stability of nanodrugs. Therefore, in this study, a composite hydrogel (HAMA/t-GL13K) was prepared via the photocross-linking method, in which tFNAs carry GL13K. The hydrogel was injectable, biocompatible, and could be instantly photocured. It exhibited broad-spectrum antibacterial and anti-inflammatory properties by inhibiting the expression of inflammatory factors and scavenging ROS. Thereby, the hydrogel inhibited bacterial infection, shortened the wound healing time of skin defects in infected skin full-thickness defect wound models and reduced scarring. The constructed HAMA/tFNA-AMPs hydrogels exhibit the potential for clinical use in treating microbial infections and promoting wound healing.

Effects of aloe vera on burn injuries: A systematic review and meta-analysis of randomized controlled trials.

Burn injuries cause severe pain, infection risks, psychological distress, financial burdens, and mortality, necessitating effective care. Aloe vera, a traditional burn remedy, shows wound healing potential, but its analgesic effects and efficacy with varying burn severity are uncertain. This study aims to investigate aloe vera's impact on wound healing, pain management, and infection prevention in burn patients. A systematic search on PubMed, Embase, and CENTRAL was performed on 9th October 2023 for randomized controlled trials (RCTs). The risk of bias was examined using the Cochrane risk-of-bias tool (version 2), and the meta-analysis was carried out using a random-effects model. The primary outcome was wound healing time, with secondary outcomes examining pain severity and wound infection. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence for each outcome. Nine RCTs were included in the current study, of which six provided data on the primary outcome. Aloe vera significantly reduced mean wound healing time compared to other topicals [mean difference (MD) -3.76 days; 95% confidence interval (CI) -5.69 to -1.84]. Additionally, the meta-analysis of the secondary outcomes found no significant differences in pain reduction (MD -0.76 points; 95% CI -1.53 to 0.01) and wound infection risk (risk ratio 1.10; 95% CI 0.34 to 3.59) between aloe vera and control groups. In conclusion, aloe vera expedites wound healing in second-degree burn patients without increased infection risk compared to other antimicrobial agents. The analgesic effects on burn injuries remain uncertain.

Comparison of Ba-Hao burn ointment gauze and petrolatum gauze in split graft donor site healing: A randomized, prospective, and self-control study.

To assess patient comfort, wound healing, and scarring at the 6-month follow-up of split-skin graft donor sites treated with Ba-Hao burn ointment (BHBO) gauze, a compound preparation of traditional Chinese medicine since 1970s, compared with petrolatum gauze. Thirty patients admitted to the Department of Burns of the First Affiliated Hospital of Anhui Medical University between September 2021 and September 2022 participated in this randomized, prospective, self-control clinical study. After harvesting the split skin, donor sites were divided into two parts along the midline. BHBO gauze was applied to half of the donor wounds, and petrolatum gauze was applied to the other half. The wound healing time, pain scores on the postoperative Days 3, 6, and 9, and Vancouver Scar Scale (VSS) score at the 6-month follow-up were assessed. The wound healing time was significantly shorter in the BHBO group than in the control group (10.07 ± 1.48 days vs. 11.50 ± 1.74 days, p < 0.001). On postoperative Days 3 and 6, the pain scores quantified by visual analog scores were significantly lower in the BHBO group than in the control group (5.33 ± 1.54 and 4.17 ± 1.51, respectively vs. 7.57 ± 1.41 and 5.20 ± 1.47, respectively). The difference in the visual analog scale score on postoperative Day 9 between the groups was not significant (p > 0.05). Microbiological assessment revealed the absence of bacterial contamination in both groups. At the 6-month follow up, the VSS score was significantly lower in the BHBO group (6.67 ± 1.92) than in the control group (9.57 ± 1.55). BHBO resulted in faster donor-site healing, reduced postoperative pain, and improved scar quality at the 6-month follow-up than petrolatum gauze alone.

Objective: To compare the fistulectomy with mucosal advancement flap in treatment of perianal fistula in terms of mean hospital stay, frequency of anal incontinence and wound healing time. Study Design: Randomized Control Trial. Setting: Surgical OPD, DHQ and Allied Hospital, Faisalabad. Period: 1st March 2019 to 28 February 2020. Methods: Conducted on 120 (60 in each group) patients with fistula in ano presenting. Sampling technique was Non probability consecutive sampling. All the Patient age ranges from 20-55 years of either gender having perianal fistula which are low lying fistulas and with single external opening are included in study. Patients having perianal abscess, pilonidal sinus, Inflammatory bowel disease (Crohn’s disease, Ulcerative colitis) or with history of tuberculosis, HIV disease, Complex high lying fistulas with multiple external openings are excluded. Results: In our study, group A underwent fistulectomy while on group B we perform mucosal advancement flap. About 56.67%(n=34) in Group A and 50%(n=30) in Group B were between 20-40 years of age while 43.33%(n=26) in Group A and 50%(n=30) in Group B were between 41-55 years of age, mean+SD was calculated as 38.78+9.07 years and 40.12+8.89 years respectively. According to gender division 86.67%(n=52) in Group A and 78.33%(n=47) in Group B were male while 13.33%(n=8) in Group A and 21.67%(n=13) in Group B were females, mean hospital stay was calculated as 93.93+4.56 hours in Group A and 107.95+4.66 hours in Group B, p value was calculated as 0.0001 showing a significant difference between the two groups. Comparison of anal incontinence in both groups was done showing that 13.33% (n=8) in Group A and 23.33%(n=14) in Group B had anal incontinence, p value was calculated as 0.15. At one month postoperative follow-up only 4 patient (6.7%) in group A showed complete wound healing while in group B 28 patients out of 60(46.6%)showed complete wound healing, P value was calculated as 0.00167 showing a significant difference while there is no significant difference in incidence of early post-operative complications. Conclusion: We concluded that hospital stay was significantly decreased in cases with fistulectomy when compared with MAF while there was no significant difference regarding anal incontinence in both groups.

Comparison of negative pressure wound therapy against normal dressing after vascular surgeries for inguinal wounds: A systematic review and meta-analysis

BackgroundNegative Pressure Wound Therapy (NPWT) is a therapeutic technique of applying sub-atmospheric pressure to a wound to reduce inflammation, manage exudate, and promote the formation of granulation tissue. It aims to optimise the natural physiological processes of wound healing for more effective recovery, and NPWT has emerged as a promising alternative to traditional dressings. MethodsThe protocol followed in the study was prospectively registered. Appropriate search terms and Boolean operators were used to search electronic databases for relevant articles. Screening of articles was performed, and data extraction was done. The effect measure was chosen according to the nature of the variable, and the effect model was chosen as per heterogeneity. Forest plot was used to give visual feedback. ResultsThis study included 11 randomized controlled trials (13 publications) with a total of 1310 patients (1497 inguinal wounds). The NPWT group had lesser odds of developing surgical site infection (OR: 0.40; 95 % CI: 0.29–0.54; n = 1491; I2 = 20 %; p-value ≤0.00001) and lesser odds of needing surgical wound revision (OR: 0.48; 95 % CI: 0.26–0.91; n = 856; I2 = 0 %; p-value = 0.02) as compared to the normal dressing group. No significant difference was observed in duration of hospital stay, cost of care, wound healing time, or other complications. ConclusionNPWT application in inguinal wounds significantly reduces the surgical site infection and the need for wound revision in patients who have undergone vascular surgery.

Primary closure versus vertical rectus abdominis myocutaneous (VRAM) flap closure of perineal wound following abdominoperineal resection-a systematic review and meta-analysis.

Perianal wound healing and/or complications are common following abdominoperineal resection (APR). Although primary closure is commonly undertaken, myocutaneous flap closure such as vertical rectus abdominis myocutaneous flap (VRAM) is thought to improve wound healing process and outcome. A comprehensive meta-analysis was performed to compare outcomes of primary closure versus VRAM flap closure of perineal wound following APR. PubMed, MEDLINE, EMBASE, and Cochrane Central Registry of Controlled Trials were comprehensively searched until the 8th of August 2023. Included studies underwent meta-analysis to compare outcomes of primary closure versus VRAM flap closure of perineal wound following APR. The primary outcome of interest was perineal wound complications, and the secondary outcomes were abdominal wound complications, dehiscence, wound healing time, length of hospital stay, and mortality. Ten studies with 1141 patients were included. Overall, 853 patients underwent primary closure (74.8%) and 288 patients underwent VRAM (25.2%). Eight studies reported on perineal wound complications after APR: 38.2% (n = 263/688) in the primary closure group versus 32.8% (n = 80/244) in the VRAM group. Perineal complication rates were statistically significantly lower in the VRAM group versus primary closure ((M-H OR, 1.61; 95% CI 1.04-2.49; <p = 0.03). We highlight the advantage of VRAM flap closure over primary closure for perineal wounds following APR. However, tailoring operative strategy based on patient and disease factors remains important in optimising outcomes.

Potential of Curcumin in the Management of Skin Diseases.

Curcumin is a polyphenolic molecule derived from the rhizoma of Curcuma longa L. This compound has been used for centuries due to its anti-inflammatory, antioxidant, and antimicrobial properties. These make it ideal for preventing and treating skin inflammation, premature skin ageing, psoriasis, and acne. Additionally, it exhibits antiviral, antimutagenic, and antifungal effects. Curcumin provides protection against skin damage caused by prolonged exposure to UVB radiation. It reduces wound healing times and improves collagen deposition. Moreover, it increases fibroblast and vascular density in wounds. This review summarizes the available information on the therapeutic effect of curcumin in treating skin diseases. The results suggest that curcumin may be an inexpensive, well-tolerated, and effective agent for treating skin diseases. However, larger clinical trials are needed to confirm these observations due to limitations in its in vivo use, such as low bioavailability after oral administration and metabolism.

Laser hemorrhoidoplasty procedure versus harmonic scalpel hemorrhoidectomy: a comparative study for the treatment of grades III and IV hemorrhoids

Background Hemorrhoids are one of the most commonly presented diagnoses of colorectal diseases. This study aimed to evaluate and compare the outcomes of laser hemorrhoidoplasty (LHP) and harmonic scalpel hemorrhoidectomy (HSH) in the management of grades III and IV hemorrhoids, focusing on some postoperative complications. Patients and methods A randomized, controlled, clinical trial involving 34 patients with grades III and IV hemorrhoids was conducted at the General Surgery Department, Faculty of Medicine, Helwan University, from June 2022 to March 2023. Ethical considerations were adhered to, and patients provided informed consent. The groups underwent either LHP or HSH, and comprehensive patient information was collected, including demographics and preoperative assessments. Postoperative care and follow-up evaluations assessed outcomes such as pain, bleeding, discharge, wound healing, incontinence, recurrence, and stenosis. Results Demographic distribution was similar between the LHP and HSH groups, with comparable operative times. Postoperative bleeding did not significantly differ between groups. HSH was associated with more early discharge, longer wound healing times, and significantly higher postoperative pain levels up to the third week. No significant differences were observed in stenosis, incontinence, or recurrence between the two groups. Conclusion Both HSH and LHP techniques were found to be safe and effective for managing hemorrhoids. LHP demonstrated advantages, including lower postoperative pain levels, reduced seromucous discharge, and faster wound healing compared with HSH. These findings provide valuable insights for clinicians in optimizing patient care during the management of hemorrhoids.

Effect of CO2 fractional laser combined with recombinant human epidermal growth factor gel on skin barrier.

To evaluate the impact of CO2 fractional laser combined with recombinant human epidermal growth factor (rhEGF) gel on skin barrier in acne scar patients. In a retrospective analysis, we examined 105 acne scar patients admitted between July 2018 and August 2021. Of these, 51 received only CO2 fractional laser (control group), while 54 underwent a combination of CO2 fractional laser and rhEGF gel (observation group). We assessed treatment efficacy, symptom relief, skin barrier parameters, pre- and posttreatment inflammatory factors, adverse reactions, posttreatment quality of life, and patient satisfaction. The observation group exhibited a higher overall response rate, significantly shorter wound healing, scab formation, and scab detachment times. Additionally, this group showed increased stratum corneum water content, decreased pH, and transdermal water loss (TEWL), and reduced hypersensitive C-reactive protein and interleukin-6 expression posttreatment. Quality of life scores were higher, with fewer adverse reactions and greater treatment satisfaction. Combining CO2 fractional laser with rhEGF gel markedly improves acne scar treatment efficacy, enhances skin barrier function, reduces inflammation, and elevates quality of life. Its safety profile supports its broader clinical adoption.

Treatment with Wound Edges Marsupialization of Simple Anal Fistula: A Randomized Controlled Trial

Introduction: Simple anal fistula can be treated with fistulectomy or fistulotomy. Wound edges marsupialization is a part of treatment. Objectives: To find out the outcomes of the treatment with marsupialization. Methods: Sixty consecutive patients with simple anal fistula were included in this prospective randomized controlled trial study where 30 patients treated with fistulotomy were included group A &amp; 30 patients treated with fistulotomy and marsupialization were included in group B. The primary outcome variable was wound healing time while secondary outcome variables were operating time, postoperative wound size, postoperative pain using visual analogue scale (VAS), post-operative bleeding, wound infection, anal incontinence, recurrence and patient satisfaction. Results: Thirty patients were randomized to group A and 30 to group B. The operating times were significantly different between two groups (21.00±6.35 minutes vs. 28.20±6.57 minutes, P=0.0001) and Postoperative wounds were larger in group A than group B (2.07±0.90 cm2 vs 1.03±0.87 cm2). Bleeding occurred less frequently in group B than group A (10% vs 53.33%, P=0.0003) and wound discharge was observed for a significantly longer duration in group A than group B (4.10±1.8 weeks vs. 2.05±1.71 weeks, P&lt;0.0001). Postoperative wounds in group B healed earlier than group A wounds (3.85±1.19 weeks vs 6.55±1.3 weeks, P&lt;0.0001). VAS scores for postoperative pain on the first postoperative day was (4.05±1.47 vs. 5.15±1.32, P=0.0035) for the two groups. Conclusion: Marsupialization after fistulectomy significantly reduces the healing time, the risk of post-operative bleeding and size of the wound without increasing postoperative anal incontinence, recurrence and sepsis.

Surgical treatment of Paraphimosis in dogs: 4 Cases

Aim: The aim of this study was to evaluate the use of surgical methods concerning the severity of persistent paraphimosis and describe the surgical techniques. Materials and Methods: The study material consisted of 4 dogs with paraphimosis. Based on anamnesis and clinical examination, 3 dogs were diagnosed with idiopathic permanent and one dog with traumatic paraphimosis. According to diagnoses and findings, patients underwent preputial advancement, partial penile amputation, phallopexy, and total penile amputation. Results: Recurrence of disease 1 week following surgery was recorded as postoperative complication in the first patient with preputial advancement. Intermittent bleeding in the surgical field in the second patient undergoing partial penile amputation continued for 3 days. No complications were observed as a result of the preputial advancement and phallopexy procedures performed for the treatment of the third case. The surgical wound healing time was recorded as one week in the second and third cases. In the fourth case, intermittent bleeding persisted for 12 days postoperatively and mild dermatitis was noted at the surgical site. According to the information received from the patient owners on the 30th day after the surgery, it was noted that there was no recurrence of the disease and no complications were encountered. Conclusion: According to the results of our study preputial advancement surgery technique alone was unsuccessful when the length of the prolapsed penis from the prepuce was 1,5 cm or more in patients with permanent paraphimosis. In addition, in cases where the disorder of the penile shaft and urethra allows, partial penile amputation should be preferred to total penile amputation.

The effects of a synthetic epidermis spray on secondary intention wound healing in adult horses.

To evaluate secondary intention wound healing in the horse's limbs when treated with the synthetic epidermis spray (Novacika®, Cohesive S.A.S, France) or with a standard bandaging technique. Six Standardbred mares were included in the study. Four 2.5 x 2.5 cm full-thickness skin wounds were created on each thoracic limb. Two wounds were located on the dorsoproximal aspect of the cannon bone and the other two at the dorsoproximal aspect of the fetlock. Six hours after creation, wounds were randomly treated with synthetic epidermis spray or standard bandaging. The wounds were assessed every 4 days by gross visual assessment and using a 3D imaging camera. Analysis was performed with a 3D imaging application. Out of 46 wounds, 22 showed exuberant granulation tissue and were part of the standard bandaging group. Whether the wounds were treated with synthetic epidermis spray or standard bandaging, the time for healing was the same. The synthetic epidermis spray studied in this model has allowed healing without the production of exuberant granulation tissue but did not reduce the median wound healing time compared to a standard bandaging technique. The synthetic epidermis spray is potentially an interesting alternative for the management of secondary intention wound healing of superficial and non-infected distal limb wounds in adult horses on economical and practical aspects. However, all statistical inference (p-values especially) must be interpreted with caution, given the size of the sample.

V advancement eversion flap for fingertip injury: Preventing ischemia and hook-nail deformity

IntroductionTraumatic fingertip amputation is the most common type of upper extremity injuries. The V-Y advancement flap is a reliable method for reconstructing fingertip defects, but it is associated with complications such as hook-nail deformity and suture site ischemia. Here, we describe our modifications to V-Y advancement flap technique, termed as “V advancement eversion flap” and review the outcomes of this procedure in 21 patients with fingertip amputation. MethodsThis was a retrospective review of 21 consecutive patients with fingertip injury who were treated surgically using the V advancement eversion flap technique at a single trauma center between 2006 and 2019. We analyzed the age, injury location and mechanism, Allen classification, injury geometry, and objective and subjective clinical outcomes. ResultsTwenty-three fingertip amputations with defect sizes greater than 1.0 cm2 from the tip to lunula were included in this study. The mean age of the patients was 43.6 years (range, 24–65 years). The average follow-up period was 20 months (range, 12–37 months). The average wound healing time (apparent epithelization) was 29.4 days (range, 14-41 days). At the final follow-up, all flaps had healed uneventfully without noticeable hook-nail deformity. In the static two-point discrimination test, the mean value was 4.61 mm in the injured finger. Patient ratings of the outcomes were “excellent” in 18 and “good” in 5 cases. ConclusionThe V advancement eversion flap technique, when properly designed and executed in fingertip amputation cases, can minimize morbidity and result in successful wound healing without flap necrosis and hook-nail deformity.

Wound infection and healing in minimally invasive plate osteosynthesis compared with intramedullary nail for distal tibial fractures: A meta-analysis.

To systematically explore the effects of minimally invasive plate osteosynthesis (MIPO) versus intramedullary nail (IMN) on wound infection and wound healing in patients with distal tibia fractures. A computerised search of PubMed, Web of Science, Cochrane Library, Embase, Wanfang, China Biomedical Literature Database (CBM) and China National Knowledge Infrastructure databases was performed, from their inception to October 2023, to identify relevant studies on the application of MIPO and IMN in patients with distal tibial fractures. The quality of the included literature was evaluated by two researchers based on inclusion and exclusion criteria, and basic information of the literature was collected, with wound infection, postoperative complications and wound healing time as the main indicators for analysis. Stata 17.0 software was applied for analysis. Overall, 23 papers and 2099 patients were included, including 1026 patients in the MIPO group and 1073 patients in the IMN group. The results revealed, when compared with IMN treatment, patients with distal tibia fractures who underwent MIPO treatment had a lower incidence of postoperative complications (OR = 0.33, 95% CI: 0.25-0.42, p < 0.001) and a shorter wound healing time (SMD = -1.00, 95% CI: -1.51 to -0.49, p < 0.001), but the incidence of postoperative wound infection was higher (OR = 2.01, 95% CI: 1.35-3.01, p = 0.001). Both MIPO and IMN are excellent treatments for distal tibia fractures. MIPO is effective in reducing the incidence of complications as well as shortening the time of wound healing time but increases the risk of wound infection. In clinical practice, surgeons can make individual choices based on the patient's wishes and proficiency in both techniques.

Effects of loose combined cutting seton surgery on wound healing and pain in patients with high anal fistula: A meta-analysis.

A meta-analysis was conducted to evaluate the effects of loose combined cutting seton surgery on wound healing and pain in patients with high anal fistula, aiming to provide evidence-based medical evidence for surgical method selection for these patients. A comprehensive computerized search of PubMed, Cochrane Library, EMBASE, Wanfang and China National Knowledge Infrastructure databases was conducted to collect all relevant studies published up to November 2023, evaluating the effects of loose combined cutting seton surgery in treating patients with high anal fistulas. Two researchers independently screened, extracted data, and assessed the quality of the identified studies. RevMan 5.4 software was employed for data analysis. Overall, 16 articles were included, comprising 1124 patients, with 567 undergoing loose combined cutting seton surgery and 557 undergoing simple cutting seton surgery. The analysis revealed patients undergoing loose combined cutting seton surgery had a higher rate of postoperative wound healing (97.44% vs. 81.69%, odds ratio [OR]: 7.49, 95% confidence interval [CI]: 4.29-13.10, p < 0.00001), shorter wound healing time (standardized mean differences [SMD]: -1.48, 95% CI: -1.89 to -1.08, p < 0.00001), lower postoperative wound pain scores (SMD: -2.51, 95% CI: -3.51 to -1.51, p < 0.00001), and a lower rate of postoperative complications (3.43% vs. 20.83%, OR: 0.13, 95% CI: 0.05-0.31, p < 0.00001). The current evidence suggests that compared to simple cutting seton surgery, loose combined cutting seton surgery in treating high anal fistulas can promote postoperative wound healing, shorten wound healing time, alleviate pain, and reduce the incidence of postoperative complications, making it a worthy clinical practice for widespread application.

Efficacy of hydrosurgical eschar excision following MEEK microskin grafting in patients with massive burns: A retrospective study of a single center

IntroductionOne of the most common traumatic injuries, burn injuries lead to at least 180,000 deaths each year worldwide. Massive burns result in severe tissue loss and increase the rate of infection. Eschar excision with skin grafting is the gold standard of treatments for massive burns. Retaining dermis tissue is the key to ensuring the survival of skin grafts and rapidly closing exposed tissues. Traditional eschar excision with Humby or Weck knife controls the depth of excision until the dermis, but ensuring the accuracy of excision is challenging. Hydrosurgery minimizes damage to uninjured tissues during the removal of necrotic tissues. A foot pedal is used to adjust debridement depth for precise debridement. To figure out the clinical advantages and risks of using hydrosurgery in treating massive burns, this study has been conducted. MethodForty-two patients with massive burns and total body surface area (TBSA) of > 30% were treated at the First Affiliated Hospital of Anhui Medical University from May 2020 to January 2023. They underwent hydrosurgical eschar excision with MEEK microskin graft (n = 23) or tangential excision with MEEK microskin graft (n = 19). ResultNo statistically significant differences (p > 0.05) in the following demographics were found between the two groups: age, weight, TBSA, deep-partial-thickness burn, gender, inhalation injury, shock, excision area, and MEEK ratio. By contrast, statistically significant differences in per unit area of operation time, per unit area of operation spending, hospitalization cost, hospitalization duration, wound-healing time, skin graft survival, and scar quality were found between hydrosurgical excision group with MEEK microskin graft and conventional excision group with MEEK microskin graft. ConclusionThe hydrosurgical excision system showed better clinical effects for patients with massive burns.

Effect of quality nursing intervention on wound healing in patients with burns: A meta-analysis.

This meta-analysis aimed to explore the effects of quality nursing intervention on wound healing in patients with burns. A computerised search was conducted for randomised controlled trials (RCTs) on the effect of quality nursing intervention on wound healing in patients with burns in the PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases from the date of database inception to November 2023. Two researchers independently screened the literature, extracted data and performed quality assessment based on the inclusion and exclusion criteria. Stata 17.0 software was used for the data analysis. Twenty-nine RCTs involving 2637 patients with burns were included. The meta-analysis revealed that compared with conventional nursing, the implementation of quality nursing intervention in patients with burns significantly shortened the wound healing time (standardised mean difference [SMD] = -2.93, 95% confidence interval [CI]: -3.44 to -2.42, p < 0.001). The incidence of wound infections (odds ratio [OR] = 0.14, 95% CI: 0.07-0.27, p < 0.001) and complications (OR = 0.16, 95% CI: 0.11-0.23, p < 0.001) was also reduced significantly. This meta-analysis shows that applying quality nursing interventions in patients with burns can significantly shorten the wound healing time and reduce the incidence of wound infection and complications, thus promoting early patient recovery.

Injectable nanoparticle-crosslinked xyloglucan/ε-poly-l-lysine composite hydrogel with hemostatic, antimicrobial, and angiogenic properties for infected wound healing

Skin wounds are susceptible to infection, leading to severe inflammatory reactions that can progress to chronic wounds, ultimately causing significant physical and mental distress to the patient. In this study, we propose an injectable composite hydrogel achieved through one-pot gelation of oxidized xyloglucan (OXG), cationic polyamide ε-Poly-l-lysine (EPL), and surface amino-rich silicon nanoparticles (SiNPs). OXG exhibits commendable anti-inflammatory properties and provides crosslinking sites. SiNPs serve as mechanically reinforced crosslinkers, facilitating the construction of a dynamic Schiff base network. SiNPs significantly reduced the gelation time to 3 s and tripled the storage modulus of the hydrogels. Additionally, the combination of EPL and SiNPs demonstrated synergistic antimicrobial activity against both S. aureus and E. coli. Notably, the hydrogel effectively halted liver bleeding within 30 s. The hydrogel demonstrated outstanding shear-thinning and self-healing properties, crucial considerations for the design of injectable hydrogels. Furthermore, its efficacy was evaluated as a wound dressing in a mouse model with S. aureus infection. The results indicated that, compared to commercial products, the hydrogel exhibited a shorter wound healing time, decreased inflammation, thinner epithelium, increased hair follicles, enhanced neovascularization, and more substantial collagen deposition. These findings strongly suggest the promising potential of the proposed hydrogel as an effective wound dressing for the treatment of infected wounds.

Comparison Between Conservative and Operative Management of Diabetic Foot Having Bone Involvement

Objective: To compare the efficacy of conservative and operative management of diabetic foot having bone involvement. Study Design: Quasi-experimental study. Place and Duration of study: Combined Military Hospital, Rawalpindi Pakistan, from May to Dec 2022. Methodology: The study included all the patients with neuropathic diabetic foot ulcers worsened by bone involvement/osteomyelitis. All the included patients were divided randomly into two equal groups, A and B (Conservative and Operative Management Groups, respectively). They were followed up for the study period to assess the healing of the wound. All the participants of the study were given antibiotics. Outcome measures were the proportion of patients achieving primary wound healing, hospitalization time, and wound healing time. Results: In our study, we included 302 patients, amongst which 206(68.20%) were male subjects and 96(31.80%) were female subjects. The mean age was 33.89±7.57 years. The proportion of patients achieving primary wound healing in the Conservative Management-Group was 121(80.13%), and in the Operative Management-Group, it was 132(87.42%) (p=0.086). However, the difference between the duration of hospitalization and the time of wound healing was statistically insignificant (p-values of 0.199 and 0.538, respectively). Conclusion: Conservative management with antibiotics alone may be a good alternative to operative management, avoiding surgical complications and costs.

Clinical Study of Rh-bFGF Combined With Collagen Sponge in the Treatment of Maxillofacial Deep Ⅱ Degree Burn.

To observe the clinical effect of recombinant human alkaline fibroblast growth factor (rh-bFGF) combined with collagen sponge in the treatment of maxillofacial deepⅡ degree burn. From January 2019 to January 2022, 96 patients with maxillofacial deep Ⅱ degree burns were randomly divided into a control group (N=48) and an observation group (N=48). The observation group was treated with rh-bFGF and collagen sponge after debridement, whereas the control group was treated with silver sulfadiazine ointment after debridement. The healing rate and healing time of the wounds were observed, interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-10, epidermal growth factor (EGF), endothelial growth factor growth factor (VEGF), and metalloproteinase tissue inhibitor 1 (TIMP-1) were measured. Vancouver Scar Scale (VSS) was used to evaluate the local scar at 6 months after wound healing in both groups. On the 10th, 14th, and 21st day of treatment, the wound healing rate in the observation group was higher than that in the control group (P<0.05), the wound healing time in the observation group was lower than that in the control group (P<0.05), and on the 14th day of treatment, the levels of TNF-α and IL-6 in the observation group were lower than those in the control group (P<0.05). The levels of IL-10 in the observation group were higher than those in the control group (P<0.05). The levels of EGF, VEGF, and TIMP-1 in the observation group were higher than those in the control group (P<0.05), and the scores of VSS in the observation group were lower than those in the control group (P<0.05). Rh-bFGF combined with collagen sponge can decrease the levels of TNF-α and IL-6 and increase the levels of IL-10, which can control the inflammation effectively, at the same time, it can increase the level of EGF, VEGF, and TIMP-1, promote wound healing, and reduce scar hyperplasia. The treatment protocol is simple, safe, effective, and suitable for clinical application.
