    Frequent repositioning is important to prevent pressure ulcer (PU) development, by relieving pressure and recovering damages on skin areas induced by repetitive loading. Although repositioning is the gold standard to prevent PU, there is currently no strategy for determining tissue condition under preventive approaches. In this study, the peak reactive hyperemia (RH) trends and ultrasonographic (US) features are compared with the tissue condition under histopathological examination to determine the potential use of these features in determining the tissue condition noninvasively. Twenty-one male Sprague-Dawley rats (seven per group), with body weight of 385-485 g, were categorized into three groups and subjected to different recovery times, each with three repetitive loading cycles at skin tissues above of right trochanter area. The first, second, and third groups were subjected to short (3 minutes), moderate (10 minutes), and prolonged (40 minutes) recovery, respectively, while applying fixed loading time and pressure (10 minutes and 50 mmHg, respectively), to provide different degree of recovery and tissue conditions (tissue damage and tissue recovery). Peak RH was measured in the three cycles to determine RH trend (increasing, decreasing, and inconsistent). All rat tissues were evaluated using ultrasound at pre- and post-experiment and rated by two raters to categorize the severity of tissue changes (no, mild, moderate, and severe). The tissue condition was also evaluated using histopathological examination to distinguish between normal and abnormal tissues. Most of the samples with increasing RH trend is related to abnormal tissue (71%); while inconsistent RH trends is more related to normal tissue (82%). There is no relationship between the tissue conditions evaluated under ultrasonographic and histopathological examination. Peak RH trend over repetitive loading may serve as a new feature for determining the tissue condition that leading to pressure ulcer.

    Nair H, Venkateshwaran N, Seetharaman S S, Deng W, Uthaipaisanwong A, Galea E
    J Wound Care, 2021 Apr 01;30(Sup4):S42-S52.
    PMID: 33856929 DOI: 10.12968/jowc.2021.30.Sup4.S42
    OBJECTIVE: Management of chronic wounds remains one of the major challenges for health professionals and patients. An evidence-based decision is important to ensure that patients are receiving the best treatment proven to reduce healing time and improve outcomes, including economic benefits and patients' health-related quality of life (HRQoL). Due to recent restrictions because of the COVID-19 pandemic, including closure of wound care centres within hospitals and a drop in patient volume, chronic wound management needs simple-to-use dressings which are still effective and evidence-based solutions. This systematic review was conducted to identify the clinical evidence available on a sucrose octasulfate dressing (TLC-NOSF, UrgoStart dressing range, Laboratoires Urgo, France) to explore its efficacy in the management of chronic wounds, particularly lower limb ulcers, diabetic foot ulcers and pressure ulcers.

    METHOD: A literature search of PubMed, Cochrane Library and Google Scholar was conducted based on the PICO model (patient/population, intervention, comparison and outcomes) to retrieve publications of different levels of evidence in order to evaluate outcomes of the use of TLC-NOSF dressings.

    RESULTS: A total of 21 publications of different levels, ranging from double-blind randomised control trials to case reports, involving over 12,000 patients, were identified through PubMed, with a further eight publications through Google Scholar and two publications through Cochrane Library. A total of seven results were omitted due to the lack of relevance or repetition.

    CONCLUSION: All the evidence provided suggest that these dressings provide clinicians with an evidence-based option for the management of chronic wounds; that the TLC-NOSF dressings are beneficial in promoting the healing process, reducing healing times, enhancing patients' HRQoL, and in allowing a more cost-effective procedure.

    Wound healing is a complex process of recovering the forms and functions of injured tissues. The process is tightly regulated by multiple growth factors and cytokines released at the wound site. Any alterations that disrupt the healing processes would worsen the tissue damage and prolong repair process. Various conditions may contribute to impaired wound healing, including infections, underlying diseases and medications. Numerous studies on the potential of natural products with anti-inflammatory, antioxidant, antibacterial and pro-collagen synthesis properties as wound healing agents have been performed. Their medicinal properties can be contributed by the content of bioactive phytochemical constituents such as alkaloids, essential oils, flavonoids, tannins, saponins, and phenolic compounds in the natural products. This review highlights the in vitro, in vivo and clinical studies on wound healing promotions by the selected natural products and the mechanisms involved.

    Kim JT, Sasidaran R
    Aesthetic Plast Surg, 2017 Dec;41(6):1362-1374.
    PMID: 28849246 DOI: 10.1007/s00266-017-0962-4
    INTRODUCTION: Autogenous grafting with lipoaspirate and dermo-fat grafting are popular techniques employed by plastic surgeons for correcting small volume facial defects and contour deformities. These techniques however present certain disadvantages. In this article, we present the use of the buccal fat pad graft as an alternative method of correcting such facial deformities.

    PATIENTS AND METHODS: Free buccal fat pad grafting was carried out in 15 patients in our institution. All were harvested using an intraoral approach. The buccal fat pad graft was used to correct periorbital contour depressions, nasal tip deformities, as a camouflage graft over exposed silicon nasal implants and as a filler in the depression deformity after mass excision.

    RESULTS: All 15 patients demonstrated good contour deformity correction without a significant graft resorption up to 3 years of follow-up. There were no donor site complications. The amount used ranged from 1 to 5 cc in volume as a spacer or barrier for the moderate-sized volume defect or depression, even though more than 5 cc of fat graft could be harvested if required.

    CONCLUSION: In conclusion, the buccal fat pad graft represents an easy, expedient and exceptional tool for the correction of contour deformities, volume replacement or for aesthetic augmentation.

    Subramaniam T, Fauzi MB, Lokanathan Y, Law JX
    Int J Mol Sci, 2021 Jun 17;22(12).
    PMID: 34204292 DOI: 10.3390/ijms22126486
    Skin injury is quite common, and the wound healing is a complex process involving many types of cells, the extracellular matrix, and soluble mediators. Cell differentiation, migration, and proliferation are essential in restoring the integrity of the injured tissue. Despite the advances in science and technology, we have yet to find the ideal dressing that can support the healing of cutaneous wounds effectively, particularly for difficult-to-heal chronic wounds such as diabetic foot ulcers, bed sores, and venous ulcers. Hence, there is a need to identify and incorporate new ideas and methods to design a more effective dressing that not only can expedite wound healing but also can reduce scarring. Calcium has been identified to influence the wound healing process. This review explores the functions and roles of calcium in skin regeneration and reconstruction during would healing. Furthermore, this review also investigates the possibility of incorporating calcium into scaffolds and examines how it modulates cutaneous wound healing. In summary, the preliminary findings are promising. However, some challenges remain to be addressed before calcium can be used for cutaneous wound healing in clinical settings.

  6. Full-thickness skin wound healing using autologous keratinocytes and dermal fibroblasts with fibrin: bilayered versus single-layered substitute
    Idrus RB, Rameli MA, Low KC, Law JX, Chua KH, Latiff MB, et al.
    Adv Skin Wound Care, 2014 Apr;27(4):171-80.
    PMID: 24637651 DOI: 10.1097/01.ASW.0000445199.26874.9d
    Split-skin grafting (SSG) is the gold standard treatment for full-thickness skin defects. For certain patients, however, an extensive skin lesion resulted in inadequacies of the donor site. Tissue engineering offers an alternative approach by using a very small portion of an individual's skin to harvest cells for propagation and biomaterials to support the cells for implantation. The objective of this study was to determine the effectiveness of autologous bilayered tissue-engineered skin (BTES) and single-layer tissue-engineered skin composed of only keratinocytes (SLTES-K) or fibroblasts (SLTES-F) as alternatives for full-thickness wound healing in a sheep model. Full-thickness skin biopsies were harvested from adult sheep. Isolated fibroblasts were cultured using medium Ham's F12: Dulbecco modified Eagle medium supplemented with 10% fetal bovine serum, whereas the keratinocytes were cultured using Define Keratinocytes Serum Free Medium. The BTES, SLTES-K, and SLTES-F were constructed using autologous fibrin as a biomaterial. Eight full-thickness wounds were created on the dorsum of the body of the sheep. On 4 wounds, polyvinyl chloride rings were used as chambers to prevent cell migration at the edge. The wounds were observed at days 7, 14, and 21. After 3 weeks of implantation, the sheep were euthanized and the skins were harvested. The excised tissues were fixed in formalin for histological examination via hematoxylin-eosin, Masson trichrome, and elastin van Gieson staining. The results showed that BTES, SLTES-K, and SLTES-F promote wound healing in nonchambered and chambered wounds, and BTES demonstrated the best healing potential. In conclusion, BTES proved to be an effective tissue-engineered construct that can promote the healing of full-thickness skin lesions. With the support of further clinical trials, this procedure could be an alternative to SSG for patients with partial- and full-thickness burns.

  9. The use of glycerol-preserved skin allograft in conjunction with reconstructive and flap surgery: seven years of experience
    Saad AZ, Halim AS, Khoo TL
    J Reconstr Microsurg, 2011 Feb;27(2):103-8.
    PMID: 20976667 DOI: 10.1055/s-0030-1268208
    Major reconstructive surgery may be extensive and prolonged, and it may cause edema and compromise the flap pedicle if closed under tension. Glycerol-preserved skin allograft (GPA) can provide a means for tension-free closure and temporary cover of the wound. Seven years of analysis on GPA used in conjunction with major reconstruction was undertaken to highlight its indications, results, and outcomes. Forty-seven patients were included, aged between 9 and 73 years. Majority of patients had reconstruction following tumor resection and trauma. The main indication for use of GPA was temporary, loose cover of the wound in 44% of cases; flap pedicle protection in 31% of cases; donor site wound cover in 10%; flap monitoring in one case; and management of flap-related complications in 6% of cases. Free flap reconstruction was performed in 72% of cases. In conclusion, GPA is a useful adjunct in reconstructive surgery. It can be used temporarily to allow tension-free wound closure, as well as to protect the flap pedicle until edema subsides and the pedicle becomes stable. This latter approach allows secondary wound closure and good esthetic outcome.

    PMID: 19024969
    The angiogenic potential of native skin (NS), keratinocytes single skin equivalent (SSE-K), fibroblasts single skin equivalent (SSE-F) and bilayered skin equivalent secreting angiogenic growth factors such as transforming growth factor beta1 (TGF-beta1), vascular endothelial growth factor (VEGF), keratinocyte growth factor (KGF) and basic fibroblast growth factor (bFGF) in the in vitro systems at 24, 48, 72 hours and 7 days was compared using Enzyme-Linked Immunosorbent Assay (ELISA). Bilayered skin equivalent exhibit highest release of growth factors within 24 hours to 7 days of culture compared to NS, SSE-K and SSE-F. This proved the potential of bilayered skin equivalent in producing and sustaining growth factors release to enhance angiogenesis, fibroblasts proliferation, matrix deposition, migration and growth of keratinocytes.

    Skin is the largest organ in human system and plays a vital role as a barrier against environment and pathogens. Skin regeneration is important in tissue engineering especially in cases of chronic wounds. With the tissue engineering technology, these skins equivalent have been use clinically to repair burns and wounds. Consented redundant skin samples were obtained from patients aged 9 to 65 years old. Skin samples were digested with dispase, thus separating the epidermis and the dermis layer. The epidermis layer was trypsinized and cultured in DKSFM in 6-well plate at 37 degrees C and 5% CO2. Once confluent, the culture were trypsinized and the cells were pooled. Cells were counted using haemacytometer. Doubling time and viability were calculated and analysed. From the result, we conclude that doubling time and viability of in vitro keratinocytes cultured in DKSFM media is not age dependant.

    PMID: 16149736
    The effect of supplementing 200 mg/kg body weight palm vitamin E (PVE) and 200 mg/kg body weight alpha-tocopherol (alpha-Toc) on the healing of wounds in streptozotocin-induced diabetic rats was evaluated. The antioxidant potencies of these two preparations of vitamin E were also evaluated by determining the antioxidant enzyme activities, namely, glutathione peroxidase (GPx) and superoxide dismutase (SOD), and malondialdehyde (MDA) levels in the healing of dermal wounds. Healing was evaluated by measuring wound contractions and protein contents in the healing wounds. Cellular redistribution and collagen deposition were assessed morphologically using cross-sections of paraffin-embedded day-10 wounds stained according to the Van Gieson method. GPx and SOD activities as well as MDA levels were determined in homogenates of day-10 dermal wounds. Results showed that PVE had a greater potency to enhance wound repair and induce the increase in free radical-scavenging enzyme activities than alpha-Toc. Both PVE and alpha-Toc, however, were potent antioxidants and significantly reduced the lipid peroxidation levels in the wounds as measured by the reduction in MDA levels.

    PMID: 26042509 DOI: 10.17305/bjbms.2015.39
    The wound-healing potential of Phaleria macrocarpa was evaluated by monitoring the levels of inflammatory mediators, collagen, and antioxidant enzymes. Experimentally, two-centimeter-wide full-thickness-deep skin excision wounds were created on the posterior neck area of the rats. The wounds were topically treated with gum acacia as a vehicle in the control group, intrasite gel in the reference group, and 100 and 200 mg/mL P. macrocarpa ‎fruit extract in the treatment group. Granulation tissues were excised on the 15th day and were further processed for histological and biochemical analyzes. Wound healing was evaluated by measuring the contractions and protein contents of the wounds. Cellular redistribution and collagen deposition were assessed morphologically using Masson's trichrome stain. Superoxide dismutase (SOD) and catalase (CAT) activities, along with malondialdehyde (MDA) level were determined in skin tissue homogenates of the dermal wounds. Serum levels of transforming growth factor beta 1 (TGF-β1) and tumor necrosis factor alpha (TNF-α) were evaluated in all the animals. A significant decrease in wound area was caused by a significant increase in TGF-β1 level in the treated groups. Decrease in TNF-α level and increase in the collagen formation were also observed in the treated groups. Topical treatment with P. macrocarpa fruit extract increased the SOD and CAT activities in the healing wounds, thereby significantly increasing MDA level. The topical treatment with P. macrocarpa fruit extract showed significant healing effect on excision wounds and demonstrated an important role in the inflammation process by increasing antioxidant enzyme activities, thereby accelerating the wound healing process and reducing tissue injury.

  16. Fulltext A preliminary study comparing the use of allogenic chondrogenic pre-differentiated and undifferentiated mesenchymal stem cells for the repair of full thickness articular cartilage defects in rabbits
    Dashtdar H, Rothan HA, Tay T, Ahmad RE, Ali R, Tay LX, et al.
    J Orthop Res, 2011 Sep;29(9):1336-42.
    PMID: 21445989 DOI: 10.1002/jor.21413
    Chondrogenic differentiated mesenchymal stem cells (CMSCs) have been shown to produce superior chondrogenic expression markers in vitro. However, the use of these cells in vivo has not been fully explored. In this study, in vivo assessment of cartilage repair potential between allogenic-derived chondrogenic pre-differentiated mesenchymal stem cells and undifferentiated MSCs (MSCs) were compared. Bilateral full thickness cartilage defects were created on the medial femoral condyles of 12 rabbits (n = 12). Rabbits were divided into two groups. In one group, the defects in the right knees were repaired using alginate encapsulated MSCs while in the second group, CMSCs were used. The animals were sacrificed and the repaired and control knees were assessed at 3 and 6 months after implantation. Quantitative analysis was performed by measuring the Glycosaminoglycans (GAGs)/total protein content. The mean Brittberg score was higher in the transplanted knees as compared to the untreated knee at 6 months (p  0.05). This study demonstrates that the use of either MSC or CMSC produced superior healing when compared to cartilage defects that were untreated. However, both cells produced comparable treatment outcomes.

    The traditional use of papaya to treat many diseases, especially skin conditions and its prohibition for consumption during pregnancy has prompted us to determine whether papaya extracts both from green and ripe fruits improve wound healing and also produce foetal toxicity. Aqueous extracts of green papaya epicarp (GPE) and ripe papaya epicarp (RPE) were applied on induced wounds on mice. GPE treatment induced complete healing in shorter periods (13 days) than that required while using RPE (17 days), sterile water (18 days) and Solcoseryl ointment (21 days). Extracts were administered orally (1 mg/g body weight/day) to pregnant mice from day 10 and onwards after conception. 3 (n=7) mice and 1 (n=6) mice given RPE and misoprostol, an abortive drug, respectively experienced embryonic resorption while this effect was observed in none of the mice given GPE (n=5) and water (n=5). The average body weight of live pups delivered by mice given GPE (1.12+/-0.04 g) was significantly lower than those delivered by mice given water (1.38+/-0.02 g). In SDS-PAGE, proteins were distributed in three bands (Mr range approximately 8-29 kDa). Band intensity at Mr approximately 28-29 kDa was higher in GPE than in RPE. In contrast, band intensity at low Mr (approximately 8 kDa) was found to be higher in RPE than in GPE. Notably, the band corresponding to Mr approximately 23-25 kDa was absent in RPE. These differences in composition may have contributed to the different wound healing and abortive effects of green and ripe papaya.

    Sensate, durable heel pad reconstruction is challenging. The present study assessed the functional outcomes after heel pad reconstruction using various flap techniques at our institution. From June 2011 to June 2016 (5-year period), 7 consecutive patients underwent heel pad reconstruction for various etiologies, with 3 microvascular free flaps (42.9%; 2 musculocutaneous flaps [66.7%] and 1 contralateral medial plantar flap [33.3%]) and 4 local pedicle flaps (57.1%; 3 instep medial plantar artery flaps [75.0%] and 1 distally based reverse sural flap [25.0%]). The patient records and demographic data were reviewed, and surgically related information was obtained and analyzed. The subjective components of the American Orthopaedic Foot and Ankle Society hindfoot clinical ratings scale were used to evaluate the pain and functional outcomes. Sensation was assessed using Semmes-Weinstein monofilaments, and ulcer recurrence was recorded. The mean age of the patients was 41.7 (range 11 to 70) years, the mean defect size was 59 (range 12 to 270) cm2, and the mean follow-up duration was 22 (range 15 to 43) months. Complete flap survival was achieved without significant complications in all 7 patients. Patients treated with the sensate medial plantar artery flap recorded the highest mean American Orthopaedic Foot and Ankle Society score of 57.3 (maximum score of 60) and experienced a return of deep sensation at 6 (range 6 to 24) months and protective sensation at 1 year. This was followed by the reverse sural flap and the musculocutaneous flap. No recurrent heel ulceration was observed in our series of patients. In conclusion, the sensate medial plantar flap is a satisfactory method for coverage of small- to moderate-size heel defects.

    Open fracture Gustilo-Anderson grade IIIC is associated with higher risk of infection and problems with soft tissue coverage. Various methods have been used for soft tissue coverage in open fractures with large skin defect. We report a case of a patient who had grade IIIC open fracture of the tibia with posterior tibial artery injury. The patient underwent external fixation and reduction. Because of potential compartment syndrome after vascular repair, fasciotomy of the posterior compartment was performed. This wound, however, became infected and because of further debridement, gave rise to a large skin defect. A tissue engineered skin construct, MyDermTM was employed to cover this large defect. Complete wound closure was achieved 35 days postimplantation. The patient then underwent plating of the tibia for nonunion with no adverse effect to the grafted site. The tibia eventually healed 5 months postplating, and the cosmetic appearance of the newly formed skin was satisfactory.
