Venous leg ulcers can lead to debilitation and a decrease in quality of life and can require costly treatments. Compression therapy remains the foundation of conservative treatment. However, some ulcers become indolent, chronic, and unresolved for years, even with adherence to standard of care. Here, the authors describe the case of a 56-year-old male patient with a recalcitrant recurrent distal leg ulcer. The ulcer was treated initially with debridement and compression therapy, respectively, and then subsequently with hyaluronic acid sodium salt 0...

Metformin is a biguanide widely prescribed as an antidiabetic drug for type 2 diabetes mellitus patients. The purpose of this study was to observe the effects of the new metformin derivative, HL156A, on human oral cancer cell and to investigate its possible mechanisms. It was observed that HL156A significantly decreased FaDu and YD-10B cell viability and colony formation in a dose dependent manner. HL156A also markedly reduced wound closure and migration of FaDu and YD-10B cells. We observed that HL156A decreased mitochondrial membrane potential and induced ROS levels and apoptotic cells with caspase-3 and -9 activation...

Conditioned medium (CM) is a new treatment modality in regenerative medicine and has shown a successful outcome in wound healing. We recently introduced extracellular matrix/stromal vascular fraction gel (ECM/SVF-gel), an adipose-derived stem cell and adipose native extracellular matrix-enriched product for cytotherapy. This study aimed to evaluate the effect of CM from ECM/SVF-gel (Gel-CM) on wound healing compared with the conventional CM from adipose tissue (Adi-CM) and stem cell (SVF-CM). In vitro wound healing effect of three CMs on keratinocytes and fibroblasts was evaluated in terms of proliferation property, migratory property, and extracellular matrix production...

Both early and advanced stage laryngeal cancers are treated with organ-preserving strategies including radiation alone or concurrent chemoradiotherapy. While organ-preserving modalities have proven effective in eradicating cancer while also preserving laryngeal function, there remains a proportion of cases where residual or recurrent cancer prevails, or conversely, where radiotherapy renders a larynx dysfunctional. In these circumstances, salvage total laryngectomy is often the surgical treatment. The effects of radiotherapy to the neck, amplified by chemotherapy, can create an inhospitable surgical environment, making the salvage laryngectomy an operation fraught with the potential for major complications such as the dreaded pharyngocutaneous fistula...

Background: Distal tibial fractures are common injuries that are prone to complications and require careful management. The use of medial periarticular locking plates is an established modality in the treatment if these fractures. These plates are inserted using the minimally invasive plate osteosynthesis (MIPO) or open technique. Our study looks at the soft tissue complications associated with the use of medial locking plates in the management of these fractures. Methods: This was a retrospective study carried out at a tertiary care university hospital in an urban setting...

A fully synthetic electrospun matrix was compared to a bi-layered xenograft in the healing of full thickness cutaneous wounds in Yucatan miniature swine. Full thickness wounds were created along the dorsum, to which these matrices were applied. The wound area was measured over the course of healing and wound tissue was scored for evidence of inflammation and healing. Animals were sacrificed at Day 15 and Day 30 and tissue samples from the wound site were harvested for histopathological analysis to evaluate inflammation and tissue healing as evidenced by granulation tissue, collagen maturation, vascularization, and epithelialization...

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a severe adverse reaction experienced by some individuals to certain medicines commonly used in the treatment of cancer and osteoporosis (e.g. bisphosphonates, denosumab and antiangiogenic agents) and involves the progressive destruction of bone in the mandible or maxilla. Depending on the drug, its dosage, and the duration of exposure, the occurrence of this adverse drug reaction may be rare (e.g. following the oral administration of bisphosphonate or denosumab treatments for osteoporosis, or antiangiogenic agent-targeted cancer treatment) or common (e...

Shape memory materials have emerged as an important class of materials in medicine due to their ability to change shape in response to a specific stimulus, enabling the simplification of medical procedures, use of minimally invasive techniques, and access to new treatment modalities. Shape memory polymers, in particular, are well suited for such applications given their excellent shape memory performance, tunable materials properties, minimal toxicity, and potential for biodegradation and resorption. This review provides an overview of biodegradable shape memory polymers that have been used in medical applications...

INTRODUCTION: With advanced-stage head and neck cancers, patients may develop large and/or complex wounds despite multiple reconstruction attempts. Wound coverage may require novel approaches to palliate the patient. METHOD: We present the case of a 56-year-old female with advanced squamous cell carcinoma of the scalp and skull who required multiple surgical interventions. Despite our best reconstructive efforts, the patient subsequently developed scalp infection and sepsis, necessitating further debridement for source control...

PURPOSE: In intraoral bone grafting, tension-free coverage of the recipient site with periosteal flap results in optimal wound closure. Tissue expansion could be a suitable modality to obtain soft tissue in the oral cavity. The aim of this study was to assess the histology of the periosteum after subperiosteal expansion in the rabbit scalp. MATERIALS AND METHODS: In this animal study, 6 rectangular tissue expanders were placed in the skulls of 6 male white New Zealand rabbits; in 6 control rabbits, an incision was made to the periosteum but no expansion was performed...

Recent advances in laser surgery and our understanding of wound healing have ushered in a new era of trauma and burn scar management. Traditional therapy has centered around scar excision followed by primary closure or tissue replacement with flaps and grafts. This approach represents a perpetuation of the common fallacy that extensive scar improvement requires extensive surgical intervention. Laser surgery in conjunction with pharmacotherapy and minor tissue-conserving surgery produces well-healed and remodeled existing tissue that provides the most natural appearance and function of the skin...

Tissue adhesives have emerged as an alternative to sutures and staples for wound closure and reconnection of injured tissues after surgery or trauma. Owing to their convenience and effectiveness, these adhesives have received growing attention particularly in minimally invasive procedures. For safe and accurate applications, tissue adhesives should be detectable via clinical imaging modalities and be highly biocompatible for intracorporeal procedures. However, few adhesives meet all these requirements. Herein, we show that biocompatible tantalum oxide/silica core/shell nanoparticles (TSNs) exhibit not only high contrast effects for real-time imaging but also strong adhesive properties...

INTRODUCTION: Animal inflicted injuries to the face and neck are becoming much more common as people lavish affection on pets. Injuries caused by animal attacks to the face can cause complex injuries to soft and hard tissues, presented as perforations, lacerations, crushes, avulsion or fractures. An uncountable number of bacteria and virus can be found in such injuries, with a potential pathological effect to humans, regarding infections. Although the infection rate is low due to excellent blood supply to face, the injuries have disfiguring effect with possible psychological repercussion to the patients...
