INTRODUCTION: In the treatment of Gustilo Type 3B open tibial fractures, it is important to perform soft tissue reconstruction and bone reconstruction simultaneously. Gastrocnemius muscle and soleus muscle flaps are generally used as rotational flaps for the tibia. The distal third of the tibia can often not be covered with the gastrocnemius muscle and soleus muscle flaps. Treatment distal to the distal third of the tibia is difficult because fewer flap options are available. In the present report, we describe our experience with a Gustilo Type 3B open tibial fracture treated by gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure...

BACKGROUND: Bone-exposed wounds with intact or defected periosteum are difficult to heal. To provide relevant experimental evidence for guidance of clinical therapy, we established a rabbit model to compare the efficacies of negative pressure wound therapy (NPWT) and conventional guaze dressing therapy on the healing of cranial bone-exposed wounds. METHODS: Full-thickness excisional circular wounds of 2.0 cm in diameter with exposed bones covered with or without periosteum were created at the parietal regions in 88 rabbits that were further randomly divided into the following treatment groups: periosteum-intact wounds treated with conventional vaseline gauze dressings (P + Control group), periosteum-intact wounds treated with NPWT (P + NPWT group), periosteum-lacking wounds treated with conventional vaseline gauze dressings (P-Control group), and periosteum-lacking wounds treated with NPWT (P-NPWT group)...

OBJECTIVE: Strict blackout discipline is extremely important for all military units. To be able to effectively determine wound characteristics and perform the necessary interventions at nighttime, vision and light restrictions can be mitigated through the use of tactical night vision goggles (NVGs). The lamp of the classical laryngoscope (CL) can be seen with the naked eye; infrared light, on the other hand, cannot be perceived without the use of NVGs. The aim of the study is to evaluate the safety of endotracheal intubation (ETI) procedures in the dark under tactically safe conditions with modified laryngoscope (ML) model...

Artificial skin has achieved considerable therapeutic results in clinical practice. However, artificial skin treatments for wounds in diabetic patients with impeded blood flow or with large wounds might be prolonged. Cell-based therapies have appeared as a new technique for the treatment of diabetic ulcers, and cell-sheet engineering has improved the efficacy of cell transplantation. A number of reports have suggested that adipose-derived stem cells (ASCs), a type of mesenchymal stromal cell (MSC), exhibit therapeutic potential due to their relative abundance in adipose tissue and their accessibility for collection when compared to MSCs from other tissues...

There are several artificial dermis commonly use to cover the wound and promote healing. The major goal of wound management is fast and scarless healing. However, there is no ideal skin substitute, that is effective to accelerate wound healing without scar formation. Artificial dermis substitute also has some drawbacks, such as high cost, insufficient available period and donor pathogen infection. To overcome these problems, we developed duck's feet collagen (DFC) sponge as artificial dermal substitutes for the treatment of full-thickness skin defects...

Hydrogels have emerged as a highly interdisciplinary topic as they play a significant role for a vast number of applications. They have been studied extensively as materials for contact lenses, wound dressing and as filler material in soft-tissue augmentation, in which classical polymer backbones such as hydroxyethylmethacrylate (HEMA) are typically employed. More recently, polysaccharides have received attention, particularly in the fields of regenerative medicine and tissue engineering, as ideal candidate materials for artificial extracellular matrices (ECM)...

Enamel is the covering tissue of teeth, made of regularly arranged hydroxyapatite crystals deposited on an organic matrix composed of 90% amelogenin that is completely degraded at the end of the enamel formation process. Amelogenin has a biomineralizing activity, forming nanoparticles or nanoribbons that guide hydroxyapatite deposit, and regenerative functions in bone and vascular tissue and in wound healing. Biotechnological products containing amelogenin seem to facilitate these processes. Here, we describe the production of human amelogenin in plants by transient transformation of Nicotiana benthamiana with constructs carrying synthetic genes with optimized human or plant codons...

PurposeTo describe the use of an acellular dermal allograft (AlloDerm) for patients with insufficient conjunctiva during evisceration and implantation surgery.Patients and methodsThe medical records of six patients with insufficient conjunctiva during evisceration surgery were reviewed. It was not possible to close the Tenon's capsule and conjunctiva without wound tension in these patients, so AlloDerm was placed over the sclera, and the edges were sutured with adjacent conjunctiva without tension. The size of the bare AlloDerm graft was measured in all patients...

OBJECTIVE: Facial keloids commonly occur in young patients. Multiple keloid masses often converge into a large lesion on the face, representing a significant obstacle to keloid mass excision and reconstruction. We describe a new surgical method that excises the keloid mass and resurfaces the wound by saving the keloid skin as a skin flap during facial keloid treatment. METHODS: Forty-five patients with facial keloids were treated in our department between January 2013 and January 2016...

In response to injury, epithelial cells migrate and proliferate to cover denuded mucosal surfaces and repair the barrier defect. This process is orchestrated by dynamic crosstalk between immune cells and the epithelium; however, the mechanisms involved remain incompletely understood. Here, we report that IL-10 was rapidly induced following intestinal mucosal injury and was required for optimal intestinal mucosal wound closure. Conditional deletion of IL-10 specifically in CD11c-expressing cells in vivo implicated macrophages as a critical innate immune contributor to IL-10-induced wound closure...

According to the latest report from the World Health Organization, an estimated 265,000 deaths still occur every year as a direct result of burn injuries. A widespread range of these deaths induced by burn wound happens in low- and middle-income countries, where survivors face a lifetime of morbidity. Most of the deaths occur due to infections when a high percentage of the external regions of the body area is affected. Microbial nutrient availability, skin barrier disruption, and vascular supply destruction in burn injuries as well as systemic immunosuppression are important parameters that cause burns to be susceptible to infections...

Diabetic foot ulcers may result in loss of an extremity and may even lead to mortality. The use of comprehensive foot care programs which include early screening and evaluation of problems, foot care education, preventive therapy and referral to specialists has been shown to reduce amputation rates by 49-85 [percent]. A 51-year-old woman with Type 2 diabetes under surveillance for nine months was referred from the emergency department. She presented with an entirely inflamed right foot with ulcer covering two-thirds proximal of the foot for 30 days' duration...

IPF is a specific form of chronic fibrosing interstitial pneumonia of unknown cause, characterized by progressive worsening in lung function and an unfavorable prognosis. Current concepts on IPF pathogenesis are based on a dysregulated wound healing response, leading to an over production of extracellular matrix. Based on recent research however, several other mechanisms are now proposed as potential targets for novel therapeutic strategies. Areas covered: This review analyzes the current investigational strategies targeting extracellular matrix deposition, tyrosine-kinase antagonism, immune and autoimmune response, and cell-based therapy...

Tuberculosis (TB) continues to be a prevalent disease worldwide; an estimated one third of the world's population is infected and 2015 data from the World Health Organization show 10 million people had an active infection. Although TB often is cited as a disease that most commonly occurs in underdeveloped countries, the evolution of drug-resistant forms of TB and infection sensitivity of immunocompromised individuals have made this disease a focal point for indus- trialized countries as well. When TB is spread, it commonly affects the lungs, but it can infect any organ of the body...
