objective(s): the aim of this study was to insert nitrofurazone in a chitosan membrane to be used as a wound dressing.   materials and methods: several blend films using chitosan (cs) and polyvinyl alcohol (pva), containing nitrofurazone were prepared by means of casting/solvent evaporating technique. different characteristics such as mechanical properties, water vapor transmission rate (wvtr),...

background: in developing new products for skin care and wound treatment, biocompatibility plays a major role in the choice of ingredients. thymol, an essential oil extracted from thyme plant, exhibits outstanding antibacterial properties, but more importantly, it proves to be much more compatible to skin cells in comparison to some conventionally used antibiotic drugs and chemicals. objective:...

background: development of biodegradable and biocompatible films based on protein polymer with strong antioxidant and antibacterial activities has gradually obtained extensive concern in the world. in this study, the improvement of gelatin film properties incorporated with ferula assa-foetida essential oil (fao) as a potential antioxidant/antibacterial wound dressing film was investigated. mate...

The variety of wound types has resulted in a wide range of wound dressings, with new products frequently being introduced to target different aspects of the wound healing process. The ideal wound dressing should achieve rapid healing at a reasonable cost, with minimal inconvenience to the patient. Microcurrent dressing, a novel wound dressing with inherent electric activity, can generate low-le...

BACKGROUND Inguinal hernia is a common surgical disease. Tension-free hernioplasty is currently commonly used for its treatment, with multiple advantages such as simple surgical method, low recurrence rate, and ability to be performed in primary care hospitals, but the risk of incision infection still exists. Mild infection can be cured by local washing, dressing, and systemic antibiotics. If t...

This clinical trial aimed to evaluate the efficacy and safety of a novel wound dressing composed of hyaluronic acid (HA) and collagen (Col) containing epidermal growth factor (EGF), referred to as EGF-wound dressing. EGF-wound dressing was prepared by freeze-drying a mixed aqueous solution of high-molecular-weight HA, low-molecular-weight HA and heat-denatured Col containing EGF. EGF-wound dres...

OBJECTIVES This study aims to assess possible wound complications of tympanoplasty and tympanomastoidectomy with or without postoperative mastoid dressing. PATIENTS AND METHODS A total of 37 patients (22 females, 15 males; mean age: 23.88 years; range 9 to 64 years) who underwent middle ear or mastoid operations via postauricular incision were included in this prospective, randomized, control...

BACKGROUND One of the major risk variables for surgical site infection is wound management. Understanding infection risk factors for breast operations is essential in order to develop infection-prevention strategies and improve surgical outcomes. The aim of this trial is to assess the influence of dressing wear time on surgical site infection rates and skin colonization. Patients' perception at...

INTRODUCTION The manufacturing of complex shaped microstructures on microsystem parts in brittle materials provides a high geometrical accuracy [1]. This requirement can only be met by using microgrinding processes. There, metal bonded diamond grinding tools offer a remarkable potential due to their favorable wear behavior [2]. However, the dressing of complex microprofiles on these tools is no...

We describe the in situ production of a burn wound dressing applied to eschar that completely isolates burned tissue from contamination with Pseudomonas aeruginosa. Anesthetized, adult rats were subjected to a scald burn over 10% of their body surfaces. One-half hour later a test dressing presumed to be a barrier to bacterial contamination of the wound was applied to the burned surface. Tannic ...
