BACKGROUND As patients with thoracic duct injuries often suffer from severe local soft tissue defects, integrated surgical treatment is needed to achieve damage repair and wound closure. However, thoracic duct chylous fistula is rare in burn patients, although it typically involves severe soft tissue damage in the neck or chest. CASE REPORT A 32-year-old male patient fell after accidentally contacting an electric current (380 V) and knocked over a barrel of sulfuric acid. The sulfuric acid continuously poured onto his left neck and chest, causing combined electrical and sulfuric acid burn injuries to his anterior and posterior torso, and various parts of his limbs (25% of his total body surface area)...

INTRODUCTION: Scald burns, which heal in less than 14 days, are seen to be at low risk of hypertrophic scar (HTS) formation. Consequently surgery is usually reserved for scalds likely to take more than 14 days to heal. With the use of silver based dressings over the past few years, anecdotally, we have observed a tendency to improved healing of scalds with conservative management and reduced need for surgical intervention. We aimed to investigate the effect of overall healing time of paediatric scalds on HTS formation over a five-year period (2011-15)...

An innovative approach was adopted where in situ synthesized silver nanoparticles (AgNPs) from leaf extract mediated reduction of AgNO3 were simultaneously impregnated into the matrix of cellulose nanocrystals (CNCs) isolated from Dendrocalamus hamiltonii and Bambusa bambos leaves, for formation of nanobiocomposites (NCs) in film and ointment forms. Here, use of plant CNCs was chosen as an alternate to bacterial cellulose for wound dressings. NCs possessing water absorption capacity and strong antibacterial activity showed synergistic effect on in vivo skin wound healing and documented faster and significant wound closure in treated mice...

The process of wound healing is often accompanied by bacterial infection or critical colonization, resulting in protracted inflammation, delayed reepithelization, and production of pungent odors. The malodor produced by these wounds may lower health-related quality of life and produce psychological discomfort and social isolation. Current management focuses on reducing bacterial activity within the wound site and absorbing malodorous gases. For example, charcoal-based materials have been incorporated into dressing for direct adsorption of the responsible gases...

OBJECTIVE: Contact allergies can occur frequently in patients with chronic leg ulcers (CLUs), even in those with a short duration of ulcerative disease. The wide spectrum of therapeutic products promotes development of the delayed type of hypersensitivity and continuous changes in the allergens pattern, which make the diagnosis and treatment extremely difficult in many cases. A prompt diagnosis and treatment of allergic contact dermatitis (ACD) in patients suffering from CLUs is very important for a best clinical outcome of these two common diseases...

Microbial contamination in wounds leading to severe sepsis can be treated by silver-based antiseptics. However, frequent application of silver-based antiseptics, staining of skin, burning, and irritation at application site resulted to poor patient compliances. Thus, we formulated sericin- and chitosan-capped silver nanoparticle (S/C-SNP)-loaded hydrogel for accelerated wound healing and antimicrobial properties. The wound healing property of sericin, antibacterial nature of chitosan and silver, and mucoadhesive property of carbopol were utilized in development of novel wound dressing hydrogel to investigate the combined effect of these materials for effective treatment of wounds...

INTRODUCTION: The diffuse epidermal exfoliation seen in Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) is similar to skin loss in second degree burns, and many of these patients are referred for treatment at burn centers. Treatment can differ markedly from center to center, and mortality can range from 25% to 70%, including a considerable morbidity. However, our experience over a 15-year period from 2000 to 2015 with 40 patients found a mortality rate of only 10% (4/40)...

Silver nanoparticles embedded within a nanofibrous polymer matrix have significant attention in recent years as an antimicrobial wound dressing materials. Herein, we have fabricated a novel Ag-polyurethane-zein hybrid nanofibrous scaffold for wound dressing applications. AgNPs were synthesized in-situ via reduction of silver nitrate in electrospinning solution. Varying mass composition of the components showed the pronounced effect on the morphology and physicochemical properties of the composite fibers. Field-Emission Scanning Electron Microscopy (FESEM) images revealed that PU and zein with mass ratio 2:1 produced the bead-free continuous and uniformly distributed nanofibers...
