The frequent use of antibiotics against microbial infections may lead the emergence of antibiotic resistant microbial strains. To overcome these microbial strains, we need to fabricate alternative materials which can handle them. It is for this reason, we have fabricated cellulose (CE) based filter paper (FP) composite scaffolds comprising of adsorbed chitosan (CS) and sliver (Ag) nanoparticles (NPs). The AgNPs are incorporated in the CS layer of the composite scaffold. Prior to evaluate the efficacy of the scaffolds against gram positive and gram negative bacterial strains, the scaffolds were characterized for the presence of the Ag NPs with field emission scanning electron microscope (FE-SEM), fourier transform infrared (FTIR) spectroscopy and x-ray diffractometer (XRD)...

Self-adherent elastic wrap dressings are a convenient option to manage pediatric hand and finger injuries. However, when improperly applied, they have the potential to cause devastating complications. We detail in this report 5 cases of dressing-induced ischemic injury to the hand in pediatric patients with a review of the literature. All patients were treated by the senior author between 2007 and 2015 and were retrospectively reviewed for initial injury, frequency of dressing changes, presence of pain, time to evaluation by the orthopedic hand team, treatment, and outcome...

BACKGROUND: Pilonidal disease (PD) is a chronic situation which may cause pain, discomfort, inflammation, discharges, and inability to do daily routines. Among two main methods of surgery, open healing is preferred by surgeons since it associates with lower risk of recurrence; however, it could complicate the wound condition by delaying the healing process. METHODS: For this meta-analysis, a search in Medline, Embase and Scopus was performed in June 2017 with no restrictions placed on the publication date or languages...

Background: Patients presenting with large surface area burns are common in our practice; however, patients with a secondary large burn on pre-existing burn scars and grafts are rare and not reported. Case presentation: We report on an unusual case of a patient sustaining a secondary large burn to areas previously injured by a burn from a different mechanism. We discuss the potential implications when managing a case like this and suggest potential biological reasons why the skin may behave differently...

BACKGROUND: The standard treatment of necrotizing soft tissue infection (NSTI) includes extensive surgical debridement. Care of these debridements is challenging because of the size of the wound and associated pain. A potential solution is to leave the wounds open-to-air in the period after the initial debridement, allowing for regular inspection at bedside while reducing pain associated with frequent dressing changes. We evaluated the feasibility of this approach from a pain control standpoint...

Wound contact layer (WCL) dressings are intended to protect tissue during the healing process. A randomised controlled trial was undertaken to compare 2 such dressings. Outpatients with acute wounds were randomly allocated to treatment with either a soft silicone-coated WCL (intervention group, n = 59) or a lipidocolloid-impregnated WCL (control group, n = 62). At the first dressing removal (day 3), 89.8% of patients in the intervention group experienced non-painful dressing removal (defined as a pain rating <30 mm on a 100 mm visual analogue scale), compared with 73...

Diabetes mellitus comprises a multiple metabolic disorder that affects millions of people worldwide and consequentially poses challenges for clinical treatment. Among the various complications, diabetic ulcer constitutes the most prevalent associated disorder and leads to delayed wound healing. To enhance wound healing capacity, we developed structurally stabilized epidermal growth factor (ST-EGF) and basic fibroblast growth factor (ST-bFGF) to overcome limitations of commercially available EGF (CA-EGF) and bFGF (CA-bFGF), such as short half-life and loss of activity after loading onto a matrix...

The purpose of this study is to summarize the innovations of Ambroise Paré (1510-1590) on the treatment of war wounds and improving amputation technique through ligature in arteries and veins. Ambroise Paré debunked the widely accepted idea that gun powder was poisonous for wounds. He also minimized the use of cautery of wounds by his dressing methods and the application of ligature during amputations. All these innovative rationales revolutionized the practice of war surgery during the Renaissance and paved the way for the introduction of modern surgery...

The α7 nicotinic acetylcholine receptor (α7-nAChR) is associated with inflammation, re-epithelialization, and angiogenesis in wound healing process. A recent study demonstrated that PNU-282987, a selective agonist of α7-nAChR, accelerates the repair of diabetic excisional wounds. Whether α7-nAChR activation promotes non-diabetic wounds healing is unknown. The aim of this study was to evaluate the effects of α7-nAChR activation on non-diabetic wound healing. The effects were evaluated in two wound models...

There is a paucity of literature describing the management of recurrent symptomatic postoperative epidural hematoma or uncontrollable intraoperative hemorrhage in posterior spine surgery. Traditional management with hematoma evacuation and wound closure over suction drains may not be effective in certain cases, and it can lead to recurrence and neurological injury. The authors report 3 cases of recurrent symptomatic postoperative epidural hematoma successfully managed with novel open-wound negative-pressure dressing therapy (NPDT), as well as 1 case of uncontrollable intraoperative hemorrhage that was primarily managed with the same technique...

Unlike conventional physical and chemical methods, the biogenic synthesis of gold nanoparticles (GNPs) is considered a green and non-toxic approach to produce biocompatible GNPs that can be utilized in various biomedical applications. This can be achieved by using plant-derived phytochemicals to reduce gold salt into GNPs. Several green synthesized GNPs have been shown to have antibacterial effects, which can be applied in wound dressings to prevent wound infections. Therefore, the aim of this study is to synthesize biogenic GNPs from the South African Galenia africana and Hypoxis hemerocallidea plants extracts and evaluate their antibacterial activity, using the Alamar blue assay, against bacterial strains that are known to cause wound infections...

Composite film dressings composed of pluronic F127 (PL)-pectin (PC) and pluronic (PL) F127-gelatin (GL) were investigated as potential drug delivery system for wound healing. Composite films were solvent cast by blending PL with PC or GL in different ratios using glycerol (2.5%) as plasticizer. Erythromycin (ER) (0.1%) was incorporated in films as model hydrophobic antibiotic. The optimized composite films were characterized for physical appearance, morphology, mechanical profile, and thermal behavior. In addition, drug release, antibacterial activity, and cytocompatibility of the films were investigated to assess their potential as drug delivery system...

We propose a useful dressing for the post-operative care of isolated digit injuries using Coban Self-Adherent Wrap (3M). Coban is a latex-free self-adherent wrap, often used for the management of lower limb wounds and venous disease. The benefits of this dressing include a semi-rigid support to splint the digit yet it is lightweight and comfortable for the patient. The memory within the material also allows for expansion of the dressing in response to any swelling that may occur in the post-operative period, with subsequent retraction of the wrap once this subsides...
