    In the field of tissue engineering and reconstruction, the development of efficient biomaterial is in high demand to achieve uncomplicated wound healing. Chronic wounds and excessive scarring are the major complications of tissue repair and, as this inadequate healing continues to increase, novel therapies and treatments for dysfunctional skin repair and reconstruction are important. This paper reviews the various aspects of the complications related to wound healing and focuses on chitosan because of its unique function in accelerating wound healing. The proliferation of keratinocytes is essential for wound closure, and adipose-derived stem cells play a significant role in wound healing. Thus, chitosan in combination with keratinocytes and adipose-derived stem cells may act as a vehicle for delivering cells, which would increase the proliferation of keratinocytes and help complete recovery from injuries.

    The treatment of carbuncles is early administration of antibiotics and surgery. The commonest surgical approaches are saucerization, and incision and drainage (I&D). Although these two techniques are vastly different, there is a lack of evidence to determine which one produces a better outcome. Three cases of carbuncles are presented to illustrate the contrasting surgical techniques and their results. Three consecutive patients who presented to this hospital with carbuncles were treated with either saucerization or I&D. They were followed up for 8 weeks to assess their outcome. One patient had saucerization while two other patients underwent I&D of their carbuncles. Saucerization produced the shortest length of hospital stay. I&D resulted in earlier wound healing. A randomized controlled is needed to determine the best surgical approach for the treatment of carbuncles.

    Introduction: High survival rates of dental implants were commonly reported even after 10 years of follow up. Nevertheless, complications and failure may occur and the implant would need to be removed. In recent years, the use of autogenous blood products in dental surgery has increased due to its ability to aid the healing of the soft and hard tissues. Clinical case: The case demonstrated the utilisation of concentrated growth factor (CGF) from the patient’s blood for healing following conservative removal of a failed dental implant. Subsequently, the patient showed satisfactory recovery without any infections and clinical complaints. Conclusion: This explantation procedure, together with the use of CGF, may prevent the normal bone resorption and accelerate soft tissue healing. As it is biological in nature having originated from the patient’s blood, it is more readily accepted by the tissues and the risk of infection is low.

    Nasal injury following nasal surgery is an adverse consequence, and prompt treatment should be initiated. Nasal packing, either non-absorbable or absorbable, are commonly used after nasal surgery to prevent bleeding and promote wound healing. In the current study, a novel gelatine sponge crosslinked with genipin was evaluated for suitability to be used as nasal packing and compared to one of the frequently used commercial nasal packing made up of polyurethane. Gelatine at 7% and 10% (w/v) concentration were crosslinked with varying concentrations of genipin, 0.5%, 0.25%, and 0.2% (v/v). The gelatine sponges were further characterised by its water uptake ability, biodegradation, water vapour transmission rate, porosity, contact angle, chemical composition, crosslinking degree, and mechanical properties. The gelatine sponges absorbed five times more water than their dry weight and were degraded within five days. The water vapour transmission rate of the gelatine sponges was 1187.7 ± 430.2 g/(m-2 day) for 7% gelatine and 779.4 ± 375.5 g/(m-2 day) for 10% gelatine. Crosslinking of gelatine with genipin resulted in lower porosity and did not affect the wettability of gelatine sponge (contact angle: 95.3 ± 12.1° for 7% gelatine and 88.4 ± 7.2° for 10% gelatine). In terms of biodegradability, the gelatine sponges took 24-48 h to degrade completely. Genipin crosslinking improved the degradation resistance and mechanical strength of gelatine sponge. The physical and chemical properties of the gelatine sponge, i.e. biodegradability and mechanical durability, support its potential as nasal packing.

    Epithelial-mesenchymal transition (EMT) is a critical process that occurs during the embryonic development, wound healing, organ fibrosis and the onset of malignancy. Emerging evidence suggests that the EMT is involved in the invasion and metastasis of cancers. The inflammatory reaction antecedent to fibrosis in the onset of oral submucous fibrosis (OSF) and the role of EMT in its malignant transformation indicates a hitherto unexplored involvement of EMT. This review focuses on the role of EMT markers which are regulators of the EMT mediated complex network of molecular mechanisms involved in the pathogenesis of OSF and OSCC. Further the gene enrichment analysis and pathway analysis supports the association of the upregulated and downregulated genes in various EMT regulating pathways.

    The use of hybridisation strategy in biomaterials technology provides a powerful synergistic effect as a functional matrix. Silk fibroin (SF) has been widely used for drug delivery, and collagen (Col) resembles the extracellular matrix (ECM). This systematic review was performed to scrutinise the outcome of hybrid Col and SF for cutaneous wound healing. This paper reviewed the progress of related research based on in vitro and in vivo studies and the influence of the physicochemical properties of the hybrid in wound healing. The results indicated the positive outcome of hybridising Col and SF for cutaneous wound healing. The hybridisation of these biomaterials exhibits an excellent moisturising property, perfectly interconnected structure, excellent water absorption and retention capacity, an acceptable range of biodegradability, and synergistic effects in cell viability. The in vitro and in vivo studies clearly showed a promising outcome in the acceleration of cutaneous wound healing using an SF and Col hybrid scaffold. The review of this study can be used to design an appropriate hybrid scaffold for cutaneous wound healing. Therefore, this systematic review recapitulated that the hybridisation of Col and SF promoted rapid cutaneous healing through immediate wound closure and reepithelisation, with no sign of adverse events. This paper concludes on the need for further investigations of the hybrid SF and Col in the future to ensure that the hybrid biomaterials are well-suited for human skin.

    OBJECTIVE: The aim of this study is to investigate the efficacy of delivering low-level laser therapy (LLLT) in the management of dry socket at University Dental Hospital Sharjah.

    MATERIALS AND METHOD: Forty-five patients with dry socket were divided into two treatment groups. Group I dry socket patients (n = 30) received conventional treatment while group II patients (n = 15) were irradiated with LLLT at a setting of 200-mW, 6-J, continuous-wave mode using an R02 tipless handpiece (Fotona Er:YAG, Europe), on the buccal, lingual, and middle surfaces of the socket for 30 s from a delivery distance of 1 cm. Pain score and quantification of granulation tissue in the socket were recorded at 0, 4, and 7 days post-dry socket treatment.

    RESULTS: Results showed that the LLLT-irradiated group II sockets showed a much lower VAS pain score of 1-2 as early as day 4, and a richer amount of granulation tissue compared to the conventional treated group I socket. The amount and rate of granulation tissue formation in the dry socket are inversely proportional to the pain score showing significant clinical effectiveness of LLLT on promoting the healing of the dry socket, with improvement in symptoms (P = .001). Conventionally treated dry sockets take at least 7 days to match the effective healing of an LLLT-irradiated dry socket.

    CONCLUSION: LLLT irradiation influences biomodulation of dry socket healing by dampening inflammation, promoting vascularization, stimulating granulation, and controlling pain symptoms.

    CLINICAL RELEVANCE: LLLT may be an additional effective tool for managing dry sockets in general dental practice.

    The effects of topical application of Orthosiphon stamineus leaf extract on the rate of wound healing and histology of the healed wound were assessed. Four groups of adult male Sprague Dawley rats were experimentally wounded in the posterior neck area. A thin layer of blank placebo was applied topically to wounds of Group 1 rats. Wounds of experimental animals (Group 2 and 3) were dressed with placebo containing 5% and 10% O. stamineus extract, respectively. A thin layer of Intrasite gel® was applied topically to wounds of Group 4 animals as reference. Macroscopically, wounds dressed with placebo containing 5% (healed on day 14.50 ± 0.43) and 10% (healed on day 13.83 ± 0.21) O. stamineus extract each or Intrasite gel® (healed on day 13.13 ± 0.42) significantly accelerated the rate of wound healing compared to wounds dressed with blank placebo. Histological analysis of healed wounds confirmed the results. Wounds dressed with placebo containing 5%, 10% O.stamineus or Intrasite gel® showed markedly less scar width at wound enclosure and granulating tissue contained markedly more collagen, proliferating fibroblast with angiogenesis, and no inflammatory cells compared to wounds dressed with blank placebo. In conclusion, placebo containing 5% or 10% O. stamineus on extract-dressed wounds significantly accelerated the rate of wound healing in rats.

    INTRODUCTION: Despite the various methods described in producing platelet-rich plasma (PRP), it is well established that this biological product in its many preparations have been proven to enhance wound healing. However, very little have been known about the efficacy of these methods hence there is a lack of evidence in the superiority of one method over another. Thus, a study was conducted to compare these different protocols to determine which produces the highest concentration of platelets.
    METHODS: Peripheral blood was obtained from 24 healthy volunteers. Four different protocols using similar 2 step centrifugation methods of preparing PRP were applied to an equal number of samples in this study. Platelet counts were performed on whole blood (without processing), PRP preparations and platelet-poor plasma (PPP).
    RESULTS: All protocols produced higher amounts of platelet concentrates in PRP preparations than plasma. However, centrifugation at 150g for 10 minutes followed by another at 450g at 10 minutes produces significantly higher amount of platelets concentration (p<0.05)
    CONCLUSION: Optimizing the protocols to produce PRP appears to be important in obtaining a maximal yield of platelet concentrate. Here the protocol described has shown to provide significant concentration yield over all others.

    INTRODUCTION: Surgery in patients with haemophilia B carries a high risk of excessive bleeding and requires adequate haemostatic control until wound healing. Nonacog beta pegol, a long-acting recombinant glycoPEGylated factor IX (FIX), was used in the perioperative management of patients undergoing major surgery.
    AIM: To evaluate the efficacy and safety of nonacog beta pegol in patients with haemophilia B who undergo major surgery.
    METHODS: This was an open-label, multicentre, non-controlled surgery trial aimed at assessing peri- and postoperative efficacy and safety of nonacog beta pegol in 13 previously treated patients with haemophilia B. All patients received a preoperative nonacog beta pegol bolus injection of 80 IU kg-1 . Postoperatively, the patients received fixed nonacog beta pegol doses of 40 IU kg-1 , repeated at the investigator's discretion. Safety assessments included monitoring of immunogenicity and adverse events.
    RESULTS: Intraoperative haemostatic effect was rated 'excellent' or 'good' in all 13 cases. Apart from the preoperative injection, none of the patients needed additional doses of nonacog beta pegol on the day of surgery. The median number of postoperative doses of nonacog beta pegol was 2.0 from days 1 to 6 and 1.5 from days 7 to 13. No unexpected intra- or postoperative complications were observed including deaths or thromboembolic events. No patients developed inhibitors.
    CONCLUSIONS: These results indicated that nonacog beta pegol was safe and effective in the perioperative setting, allowing major surgical interventions in patients with haemophilia B with minimal peri- and postoperative concentrate consumption and infrequent injections as reported with standard FIX products.

    The purpose of this study is to assess the effectiveness of C02 laser in relieving symptoms associated with Oral lichen planus (aLP) and lichenoid lesions (aLL) and the event of healing. Six patients were selected for this study with 13 sites treated. Each lesion was ablated with C02 laser and the wound allowed to heal undisturbed. Prior to treatment, 4 patients had both unprovoked and provoked pain and 2 patients rated for provoked pain only. After laser ablation, five out of six patients treated recorded no pain / 0 pain score. One month post-laser, the treated area was almost the same colour as the surrounding normal mucosa and soft in texture in all but one patient in which there was some fibrosis and residual plaque-like patch. Weconclude that the use of C02 laser in the treatment of aLP and aLL shows positive results in relieving symptoms associated with these lesions.

    The biocompatibility and similarity of hydroxyapatite (HA) to the mineral composition of the bone has made HA a potential candidate in bone tissue engineering (BTE). Over the past few decades, its application as bone graft in combination with stem cells has gained much importance. The use of bone marrow-derived mesenchymal stromal cells (MSCs) will enhance the rate and quality of defect repair. However, application of hydroxyapatite as a material to develop a 3-dimension scaffold or carrier to support MSCs in vitro is still in its infant stage. This review will discuss the source, manufacturing methods and advantages of using HA scaffolds in bone tissue engineering applications.

    Platelet Rich Fibrin (PRF) is a natural autologous fibrin matrix and is an effective biomaterial product. The application of PRF in oral surgery is not limited to tissue regeneration, but it has been utilized in several minor and major oral surgical procedures. Numerous studies have proven that either alone or in combination with bone graft, PRF acts as bone and soft tissue regeneration and it is able to stimulate physiological wound healing. This case report will introduce the utilization of PRF combined with autogenous bone graft in restoring four walls dental socket defect due to post-surgical extraction complication and plan for implant placement in the future. It acts in the form of a resorbable membrane and stem cell connector to the bone. After 3 months post-surgery review, there was no signs of infection or tissue rejection and the harvested bone was still viable. The PRF is comparable to commercially available membrane in the market, where clinical results can be predicted and possibility of reduction in post-surgical complications is achieved. This is due to 1) its compatibility with bone graft materials notably autogenous type, 2) induced neovascularisation and 3) reduction in inflammatory reaction. Our team is confident that the result of PRF at the edentulous region for rehabilitation purposes is beneficial and cost-effective to our patients.

    This study was conducted to evaluate the effect of argan oil with the exposure of low frequency electromagnetic field (EMF) on open wound healing in mice. Eighteen male mice (20-40 g) were divided into three groups: phosphate buffer saline (PBS) as negative control, solcoseryl gel as positive control, and argan oil with the exposure of low frequency EMF, 1.2 mT (treatment group). Full thickness wounds (4 mm diameter) were induced on the shaved dorsal of the mouse. All mice were sacrificed on day 12 after the final treatment. Macroscopic observation, wound contraction rate, histopathology analysis and total protein content were examined in this study. Results showed that wounds treated with argan oil and exposed to low frequency EMF has a significant increase in wound contraction rate (p < 0.05) and total protein content (p < 0.05). Moreover, histopathological analysis on the wound tissues displayed complete re-epithelization with thick and dense collagen fibers in the argan oil with low frequency EMF exposure treated group. In conclusion, topical treatment of argan oil with low frequency EMF exposure yield a better healing progress and showed the ability to accelerate wound healing

    Initial wound care idioms were designed around a moist dressing in presumed better wound healing. As wound care advances, innovations of dressings were formed. In the Guru-UKM Method (GUM), we combined two well-established dressings producing a synergistic effect in burn wound management. Patients with deep partial thickness burns were selected for the GUM. From the time of admission, they receive 2 cycles of paraffin tulle dressings once every two days to allow demarcation, then are reassessed for suitability of the GUM technique. We discuss 7 different burn cases that presented to our Burn Unit from January 2014 – June 2015.All dressings should create a suitable moist environment for healing, yet should be a painless dressing to help the patient return to normal function as soon as possible. In burn wounds, a suitable dressing ideally also biochemically debrides fibrin and softens hardened eschar and slough, without necessitating the patient to undergo general anaesthesia and surgical debridement. The Guru-UKM Method is a combination dressing technique that facilitates optimal burn wound management.

    OBJECTIVE: Maggot debridement therapy (MDT) has seen a resurgence in recent years in the treatment of hard-to-heal wounds, as a result of rising antibiotic resistance. The sterilised larvae of Lucilia cuprina have been used in MDT in Malaysia since 2003, with encouraging results for the treatment of hard-to-heal diabetic wounds. We report a case series of 30 patients selected from our clinic by convenient sampling with diabetic lower limb ulcers treated with MDT. The average age of patients receiving MDT was >50 years. Of the 30 patients in the study, nine were female and 21 were male. All patients had underlying diabetes, two patients had leg ulcers and 28 patients had diabetic foot ulcers. Sterilised Lucilia cuprina larvae were applied via a standard method of 10 maggots per square centimetre and dressed with sterile gauze. The study endpoint was defined as ≤5% coverage with slough or necrotic tissue following three successive applications of MDT. In this study, maximum debridement of wounds was achieved in 96.6% (29 patients) of our patients, with ≤5% coverage with slough or necrotic tissue, in addition to a reduction in wound-related pain, as assessed by a visual analogue scale. No adverse events were reported. The findings of this study support the use of MDT as a safe, efficacious, and cost-effective method of managing diabetic wounds.
