INTRODUCTION: Infection is a major threat to wound healing and a leading cause of graft loss in patients undergoing meshed skin grafts (MSGs). Therefore, topical antisepsis is important in the overall treatment scheme. METHODS: An exploratory satellite group of 14 patients with infected MSGs were enrolled as part of a prospective, randomized, controlled, parallel-group, open-label, pilot Phase II study that investigated the efficacy and tolerability of 3% liposomal povidone-iodine hydrogel (PVP-ILH, Repithel(®); RepiGel(®)) versus chlorhexidine gauze in non-infected MSGs...

In the last few years, there has been an increasing tendency to use natural polymers for the fabrication of dressings for wound and burn management. Among them, alginate, a polysaccharide extracted primarily from marine algae, exhibits attractive properties being non-toxic, hydrophilic and biodegradable. The aim of this study was to characterize the in vitro biocompatibility and the efficacy of a composite polymeric material based on sodium alginate (NaAlg) and povidone iodine (PVPI) complex in a mouse model of wound healing...

Diets containing more than 20% distiller's dried grains with solubles (DDGS) reduce fat firmness in pork, but supplementation of cottonseed oil or crude glycerol may improve fat firmness. The objective of this study was to assess the effect of feeding minimally refined cottonseed oil or crude glycerol on growth performance, carcass composition, and fat quality of growing-finishing pigs. Mixed sex pigs ( = 216; 24 ± 4 kg initial BW) were blocked by BW and allotted to 1 of 3 dietary treatments: 1) a basal corn-soybean meal diet with 40% DDGS (CON), 2) CON diet plus 5% minimally refined cottonseed oil added throughout the experiment (COT), or 3) CON fed during the first 8 wk and CON + 8% crude glycerol fed during the last 6 wk of the experiment (GLY)...

BACKGROUND: Burn wounds cause high levels of morbidity and mortality worldwide. People with burns are particularly vulnerable to infections; over 75% of all burn deaths (after initial resuscitation) result from infection. Antiseptics are topical agents that act to prevent growth of micro-organisms. A wide range are used with the intention of preventing infection and promoting healing of burn wounds. OBJECTIVES: To assess the effects and safety of antiseptics for the treatment of burns in any care setting...

The First World War was a huge tragedy for mankind, but, paradoxically, it represented a source of significant progress in a broad series of human activities, including medicine, since it forced physicians to improve their knowledge in the treatment of a large number of wounded soldiers. The use of heavy artillery and machine guns, as well as chemical warfare, caused very serious and life-threatening lesions and wounds. The most frequent causes of death were not mainly related to gunshot wounds, but rather to fractures, tetanus and septic complications of infectious diseases...

BACKGROUND: A new polyurethane foam dressing impregnated with 3% povidone-iodine (Betafoam; Genewell, Seoul, Korea) was recently developed based on the hypothesis that its physical properties, including improved moisture-retention capacity and antimicrobial activity, are at least as good as those achieved with the current foam dressings that contain silver, but also associated with reduced cost and cytotoxicity to host cells. The purpose of this in vitro study was to evaluate the efficacy of Betafoam by comparing its physical properties, antimicrobial activity, and cytotoxicity with those of 3 silver foam dressings (Allevyn-Ag [Smith & Nephew, Hull, United Kingdom]; Mepilex-Ag [Mölnlycke Health Care, Gothenburg, Sweden]; and PolyMem-Ag [Ferris MFG Corp, Burr Ridge, Illinois]) used worldwide...

This study investigated whether there are differences in the ability of wound dressings to modulate certain factors known to affect wound healing. A selection of antimicrobial dressings (AQUACEL(®) Ag Extra(™) , AQUACEL(®) Ag+ Extra(™) , IODOFLEX(™) , ACTICOAT(™) 7 and PROMOGRAN PRISMA(™) matrix) were tested for their effect on both bacterial bioburden and human dermal fibroblasts. Some dressings underwent further evaluation for activity against Pseudomonas aeruginosa biofilms using a colony-drip flow reactor model...

Povidone-iodine (PVI) is principally used as an antimicrobial agent. It has been found that 0.5% PVI can attenuate congestion, edema and pain induced by pressure sores. Thus this study aimed to assess the effects of 0.5% PVI on acute skin wounds. Four full-thickness excisional wounds were generated on the dorsal skin of male Sprague-Dawley rats with a 10-mm sterile punch. Two wounds were left untreated and the other two were dressed with gauze with 0.5% PVI for 1 hour per day for the first 5 days after injury...

Examination of clinical samples indicates bacterial biofilms are present in the majority of chronic wounds, and substantial evidence suggests biofilms contribute significantly to delayed healing. Bacteria in biofilms are highly tolerant of antimicrobials, and little data exist to guide the choice of anti-biofilm wound therapy. Cadexomer iodine (CI) was recently reported to have superior efficacy compared to diverse wound dressings against Pseudomonas aeruginosa biofilms in an ex vivo model. In the current study, the strong performance of CI vs...

In December 1913, a board of medical officers was appointed to adapt new U.S. Army equipment to the needs of the Hospital Corps. One of the improvements concerned substitution of the satchel-like Hospital Corps pouch used to carry first aid equipment. A waist belt with 10 pockets, known as the medical belt, was devised, and supplied with a tourniquet, adhesive plaster, safety pins, iodine swabs, sublimated gauze, individual dressing packets, gauze bandages, aromatic spirit of ammonia, and common pins. In addition, an ax carrier accommodating a hand ax, a canteen hanger, and a pouch to carry diagnosis tags and instruments were attached to the medical belt...

Uncontrolled hemorrhage accounts for more than 30% of trauma deaths worldwide. Current hemostatic devices focus primarily on time to hemostasis, but prevention of bacterial infection is also critical for improving survival rates. In this study, we sought to improve on current devices used for hemorrhage control by combining the large volume-filling capabilities and rapid clotting of shape memory polymer (SMP) foams with the swelling capacity of hydrogels. In addition, a hydrogel composition was selected that readily complexes with elemental iodine to impart bactericidal properties to the device...

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...

BACKGROUND: Chlorhexidine skin preparation has been shown to provide highly effective antimicrobial presurgical skin cleansing. However, there is a significant risk of ocular toxicity when it is used in periocular areas. CASE DESCRIPTION: We describe 2 cases of significant corneal damage resulting from 4% chlorhexidine gluconate preoperative skin cleanser, despite the use of protective occlusive dressing over the eyes. Because of the potential for severe corneal toxicity resulting from use of chlorhexidine, alternative agents such as 10% povidone-iodine should be considered for skin preparation near periocular areas whenever possible...

INTRODUCTION: Neonatal thyrotoxicosis is a life-threatening condition with potentially irreversible neurologic sequelae. Most cases are seen in neonates born to mothers with Graves' disease. Topical iodine-induced hypothyroidism has been reported in neonates, but iodine-induced neonatal hyperthyroidism has not been described; albeit a familiar entity in adults. CASE DESCRIPTION: Herein we present a unique case of a neonate, born with a giant omphalocele, who was treated with topical povidone-iodine dressings to promote escharification, in preparation for delayed surgical closure...

After debridement and before dressing a wound with maggots of calliphorid flies, one frequently performed step is the application of antiseptics to the prepared wound bed. However, the concomitant application of antiseptic agents during maggot therapy is regarded controversial as antiseptics may interfere with maggots' viability. In this experimental in vitro study, the viability of fly maggots was investigated after exposure to various antiseptics frequently used in wound care. Here, we show that Lucilia sericata fly maggots can survive up to an hour's exposure to wound antiseptics such as octenidine, povidone-iodine or polihexanide...

Chronic venous leg ulcers (VLUs) affect up to 1% of the adult population in the developed world and present a significant financial and resource burden to health care systems. Cadexomer iodine (CI) is an antimicrobial dressing indicated for use in chronic exuding wounds. The aim of this study was to estimate the cost utility of using CI + standard care (SC) - ie, high compression multicomponent bandaging including debridement - compared with SC alone in the management of chronic (>6 months' duration) VLUs from a payer's perspective...

Zorflex is a new type of antimicrobial dressing composed of 100% activated carbon cloth. It attracts and binds bacteria to its surface, enabling them to be safely removed at dressing change. It has no reported toxic effects and can be used on either a short-or long-term basis. This article describes 4 case studies in which patients with recalcitrant chronic venous leg ulcers that were prone to recurrent infection were treated with the activated carbon cloth dressing. All of the wounds had failed to respond to antimicrobial dressings containing silver, iodine or polyhexamethylene biguanide (PHMB), and were heavily exuding and painful...

The low content of iodine (I) and selenium (Se) forms available to plants in soil is one of the main causes of their insufficient transfer in the soil-plant-consumer system. Their deficiency occurs in food in the majority of human and farm animal populations around the world. Both elements are classified as beneficial elements. However, plant response to simultaneous fertilization with I and Se has not been investigated in depth. The study (conducted in 2012-2014) included soil fertilization of carrot cv. "Kazan F1" in the following combinations: (1) Control; (2) KI; (3) KIO3; (4) Na2SeO4; (5) Na2SeO3; (6) KI+Na2SeO4; (7) KIO3+Na2SeO4; (8) KI+Na2SeO3; (9) KIO3+Na2SeO3...

In this study, the potential of cryogel bilayer wound dressing and skin regenerating graft for the treatment of surgically created full thickness wounds was evaluated. The top layer was composed of polyvinylpyrrolidone-iodine (PVP-I) cryogel and served as the antiseptic layer, while the bottom regenerative layer was made using gelatin cryogel. Both components of the bilayer showed typical features of a cryogel interconnected macropore network, rapid swelling, high water uptake capacity of about 90%. Both PVP and gelatin cryogel showed high tensile strength of 45 and 10 kPa, respectively...
