Epithelial cell dynamics can be difficult to study in intact animals or tissues. Here we use the medusa form of the hydrozoan Clytia hemisphaerica, which is covered with a monolayer of epithelial cells, to test the efficacy of an orientation-independent differential interference contrast microscope for in vivo imaging of wound healing. Orientation-independent differential interference contrast provides an unprecedented resolution phase image of epithelial cells closing a wound in a live, nontransgenic animal model...

Debridement is essential for the optimal care of venous leg ulcers. Several debridement methods with different limitations may be deployed. Trichloroacetic acid (TCA) is used for several dermatological purposes. Its application as a chemical debridement method for leg ulcers has never been explored. We designed a prospective study to determine the role of 80% TCA solution as a chemical debridement method for leg ulcers, regarding efficacy and procedure-associated pain. Chronic venous leg ulcers were treated with 3 cycles of 80% TCA solution or curettage over 1 week...

OBJECTIVE: In clinical practice, split-thickness skin graft (STSG) transplantation remains the gold standard for covering large skin defects. Currently, there is no consensus on the optimal thickness of skin grafts. The purpose of our study was to compare the early healing processes of recipient and donor wounds after STSG transplantation using grafts of different thickness. METHOD: This prospective, randomised clinical trial included 84 patients that underwent STSG transplantation surgery for post-burn, post-traumatic or postoperative skin defects...

INTRODUCTION: Artificial skin has become the treatment of choice in extensive, full-thickness thermal injuries. The longest follow-up of the healing process in burn sites covered with the Integra Bilayer Matrix Wound Dressing onto the wound published to date was at around five years after application. In our case report, we describe the clinical and histological analysis of an extensive, full-thickness thermal injury 14 years on from treatment with the bilayer matrix wound dressing. CASE STUDY: A nine-year-old boy suffered a full-thickness skin loss over 85% of his body surface area following a fire accident...

INTRODUCTION: The evolution of medical practice is resulting in increasing subspecialisation, with head, face and neck (HFN) trauma in a civilian environment usually managed by a combination of surgical specialties working as a team. However, the full combination of HFN specialties commonly available in the NHS may not be available in future UK military-led operations, necessitating the identification of a group of skill sets that could be delivered by one or more deployed surgeons. METHOD: A systematic review was undertaken to identify those surgical procedures performed to treat acute military head, face, neck and eye trauma...

Acute traumatic or surgical wounds that cannot be primarily closed often cause substantial morbidity and mortality. This often leads to increased costs from higher material expenses, more involved nursing care, and longer hospital stays. Advancements in soft tissue expansion has made it a popular alternative to facilitate early closure without the need for more complicated plastic surgical procedures. Areas Covered: In this review, we briefly elaborate on the history and biomechanics of tissue expansion and provide comprehensive descriptions of traditional internal tissue expanders and a variety of contemporary external tissue expanders...

The Lando® dermal scaffold is a newly developed, tissue-engineered dermal scaffold material. This study sought to observe its vascularization in an acute full-thickness skin-defect porcine model. There were eight Tibetan pigs in this research. Six 5 × 5 cm full-thickness skin-defect wounds were prepared on the dorsal area of each pig, which were divided into two groups. The experimental group wounds were covered by Lando® dermal scaffolds, while the other received Vaseline gauzes as blank control. At day 3, 7, 14 and 21 after injury, the general condition of wounds was observed, and wound specimens were obtained for HE staining, Masson staining and the expression of CD31, α-SMA and VEGF, which were examined by immunohistochemistry...

Collective cell migration is a fundamental process during embryogenesis and its initial occurrence, called epiboly, is an excellent in vivo model to study the physical processes involved in collective cell movements that are key to understanding organ formation, cancer invasion, and wound healing. In zebrafish, epiboly starts with a cluster of cells at one pole of the spherical embryo. These cells are actively spreading in a continuous movement toward its other pole until they fully cover the yolk. Inspired by the physics of wetting, we determine the contact angle between the cells and the yolk during epiboly...

BACKGROUND: Traumatic skin tears often occur in patients with dystrophic skin. Closing them with adhesive skin closures is useful for patients with a healthy flap, but occasionally fails to cover the entire defect. We describe a simple technique to perform mini patch grafting on the remaining raw surface without damaging healthy skin. DISCUSSION: The skin flap is spread out and fixed with adhesive skin strips to minimize defects first. Small pieces of skin are obtained by trimming the edges of the skin flap with curved tip scissors...

Land plants produce specialized low-molecular-weight metabolites to adapt to various environmental stressors, such as ultraviolet radiation, pathogen infection, wounding, and animal feeding damage. Due to the large variety of stresses, plants produce various chemicals, particularly plant species-specific alkaloids, through specialized biosynthetic pathways. In this study, using a draft genome sequence and querying known biosynthetic cytochrome P450 (P450) enzyme-encoding genes, we characterized the P450 genes involved in benzylisoquinoline alkaloid (BIA) biosynthesis in California poppy (Eschscholzia californica), as P450s are key enzymes involved in the diversification of specialized metabolism...

Overview: Although the agreed-upon standard is circumferential pathology analysis of the interface between the resected specimen and the patient, there is currently no consensus on the optimal methodology to achieve this in head and neck cancer specimens. This is most commonly conducted by either sampling the wound bed after resection or obtaining samples from the specimen. Regardless of the technique, only a fraction of the area of interest can be sampled due to the labor-intensive nature of frozen sections...

Cultured epithelial autografts (CEA) with highly expanded mesh skin grafts were used for extensive adult burns covering more than 30% of the total body surface area. A prospective study on eight patients assessed subjective and objective findings up to a 12-month follow-up. The results of wound healing for over 1:6 mesh plus CEA, gap 1:6 mesh plus CEA, and 1:3 mesh were compared at 3, 6, and 12 months using extensibility, viscoelasticity, color, and transepidermal water loss by a generalized estimating equation (GEE) or generalized linear mixed model (GLMM)...

Aqueous gels formulated using hydrophilic polymers (hydrogels) along with those based on stimuli responsive polymers (in situ gelling or gel forming systems) continue to attract increasing interest for various eye health-related applications. They allow the incorporation of a variety of ophthalmic pharmaceuticals to achieve sustained and therapeutic levels of drugs and bioactives at target ocular sites. The integration of sophisticated drug delivery technologies such as nanotechnology-based, intelligent and environment responsive systems can extend current treatment duration to provide more clinically relevant time courses (weeks and months instead of hours and days) which will inevitably reduce dose frequency, increase patient compliance and improve clinical outcomes...

Introduction: Infections occurring in the wound as a consequence of the surgery represent the surgical field infections (SFI). Tibia diaphysis fractures are common due to its exposure to the external force. Clinical signs include: pain, swelling, lower leg deformity and skin changes. Tibia in the lower extremities has an eccentric position - from the front inner side it is covered only with the skin and from the back and the outer by muscle mass. The most common pathogens are: Staphylococcus aureus, Coagulase negative Staphylococcoc aureus or S...
