Debridement is often a necessary step in wound care. In burn care, typically, surgery or enzymes are used for this purpose.

In a real-life retrospective study, the autolytic debridement properties of a concentrated surfactant gel (CSG) were assessed.

Thirty patients who had burns that ranged from superficial partial thickness to full thickness and did not exceed 10% total body surface area were evaluated retrospectively with regard to outcomes of their treatment with CSG alone or in combination with bacitracin ointment (CSG-BA). Both materials were applied daily. The hypothesis of the study was that CSG, by providing moisture to the wound in combination with debridement via micelle action, would provide debridement without the need for surgery or enzymes and would lead to healing times similar to those for wounds treated with other modalities. Burn depth was determined visually.

Of the CSG-treated burns, 88.2% were mixed partial thickness, deep partial, or full thickness, and 64.7% of these lesions reepithelialized completely or showed satisfactory healing progression within a time frame that is similar to published results with other treatment modalities. Secondary autografting was necessary in 1 lesion.

On average, the CSG-BA-treated burns were less deep and smaller than the CSG alone. Panobinostat cell line All wounds reached complete healing or showed continued healing progress.
On average, the CSG-BA-treated burns were less deep and smaller than the CSG alone. All wounds reached complete healing or showed continued healing progress.Negative pressure wound therapy (NPWT) has evolved beyond its original design as a stationary, reusable system (traditional NPWT [tNPWT]) and is now also available as a single-use, portable device (sNPWT). No established guidance exists for selecting the appropriate system to treat specific wound types in various settings. This article reviews the current practice and challenges associated with NPWT. Relevant literature was reviewed to provide a background on current practice. An online quantitative survey was performed during October and November 2018 among users of NPWT based in acute care settings across 6 countries (Australia, France, Germany, Italy, the United Kingdom, and the United States) to elucidate the operational and financial components considered in determining and/or thwarting efficacious use of NPWT. Data from recruited participants were collected, analyzed, and tabulated by an independent research company. All findings were reported as numbers/percentages. Wound size and depth, as well as the amount and/or type of exudate, were found to be among key factors in selecting NPWT; patient quality of life in terms of mobility, independence, and attitude toward treatment may be factors in adherence with prescribed care. Clinicians were not consistently knowledgeable about the financial and operational challenges of utilization presented by large fleets of NPWT pumps, nor were other institutional employees such as payers and discharge planners. Evidence-based recommendations are needed to guide decisions regarding NPWT systems, which in turn may improve therapy implementation, access to care, and patient quality of life, while driving operational and financial efficiencies for health care providers.Dermanyssus gallinae(De Geer) (Acari Dermanyssidae) is the main ectoparasite associated with laying poultry. This mite is commonly controlled by the application of synthetic chemical insecticides, wich lead to the selection of resistant populations and formation of residues in eggs. Thus, new molecules must be developed to control D. gallinae. This work evaluated the toxicity of essential oils (EOs) from Cinnamomum cassia, Cinnamomum camphora, Cinnamomum camphora var. linalooliferum, Citrus aurantium, Citrus aurantium var. bergamia, Citrus aurantifolia and Citrus reticulata var. tangerine against D. gallinae. Additionally, the chemical profiles of the most bioactive EOs were analyzed by gas chromatography coupled with mass spectrometry (GC-MS) and the major compounds were subjected to new tests using D. gallinae. The most toxic EOs against D. gallinae were evaluated for the nontarget entomopathogenic fungus Beauveria bassiana (Unioeste 88). The EOs from C. cassia (LC50 = 25.43 ± 1.0423 μg/cm3) and C. camphora var. linalooliferum (LC50 = 39.84 ± 1.9635 μg/cm3) were the most active in the fumigant bioassay and caused mortality rates of 96 and 61%, respectively. The GC-MS analysis revealed that the major constituents of EOs from C. cassia and C. camphora var. linalooliferum were trans-cinnamaldehyde and linalool, respectively. The pure compounds, trans-cinnamaldehyde (LC50 = 68.89 ± 3.1391 μg/cm3) and linalool (LC50 = 51.45 ± 1.1967 μg/cm3), were tested on D. gallinae and showed lower toxicity than the EOs. Thus, the compounds were not the only active substances produced by C. cassia and C. camphora var. linalooliferum; moreover synergism may have occurred between the substances. The EOs from C. cassia and C. camphora var. linalooliferum were also toxic to B. bassiana (Unioeste 88). Thus, EOs from C. cassia and C. camphora var. linalooliferum are promising candidates for use in D. gallinae control, but cannot be used in conjunction with the fungus B. bassiana.The development of hardpan caps has great potential in rehabilitating sulfidic and metallic tailings, which may be accelerated by using exogenous Acidithiobacillus species. The present study aims to establish a bioaugmentation process with exogenous Acidithiobacillus species for accelerating the weathering of sulfidic minerals and formation of secondary mineral gels as precursors for hardpan structure development in a microcosm experiment. Exogenous Acidithiobacillus thiooxidans (ATCC 19377) and A. ferrooxidans (DSM 14882) were inoculated in a sulfidic Pb-Zn tailing containing negligible indigenous Acidithiobacillus species for accelerating the weathering of pyrite and metal sulfides. Microspectroscopic analysis revealed that the weathering of pyrite and biotite-like minerals was rapidly accelerated by exogenous Acidithiobacillus species, leading to the formation of secondary jarosite-like mineral gels and cemented profile in the tailings. Meanwhile, approximately 28% Zn liberated from Zn-rich minerals undergoing weathering was observed to be re-immobilized by Fe-rich secondary minerals such as jarosite-like mineral.
