The role of NO as an endogenous regulator of inflammation, as an antibacterial agent and as an endogenous gasotransmitter is well established. Even so, despite a plethora of excellent wound healing data, hard-to-heal (chronic) wounds are of epidemic proportions, and still growing in number. However, yet to be established and sorely needed is the identification of a single, continuous NO mechanism of action (MoA), where phase-to-phase variance in the complex sequence of cellular and molecular wound healing may elucidate the potential for placing hard-to-heal wounds on positive healing trajectories. Hence, the objectives of this review were to: identify salient MoAs for NO in each phase of skin wound healing; and to select and validate a single MoA that is both ubiquitous and continuous in NO across acute and hard-to-heal wound sequences, and which potentiates the ability to supplementally motivate and guide the recovery of a hard-to-heal wound onto a positive healing trajectory. The search began by selecting a detailed, multipart wound healing model. Next, as guided by the literature, was the identification of salient NO functionalities for each model segment. These modes of action were then be used to identify and validate a single NO MoA that is continuous across the healing spectrum. Finally, by using the principle of 'super position' of two continuous functions, this acute healing NO MoA solution was compared to a similar solution set describing a hard-to-heal or chronic wound. As both solution sets are continuous in a NO function, the resultant 'overlay' then helped to identify and guide the use of a NO MoA capable of placing any hard-to-heal wound on a positive healing trajectory.</p>","PeriodicalId":17590,"journal":{"name":"Journal of wound care","volume":"33 12","pages":"912-925"},"PeriodicalIF":1.5,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142780601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Effect of ceramic dressings and silver-impregnated dressings on bacterial load and wound closure: a comparative study.","authors":"Febe A Bruwer, Rene Lessing","doi":"10.12968/jowc.2024.0334","DOIUrl":"https://doi.org/10.12968/jowc.2024.0334","url":null,"abstract":"<p><p>Wound healing is a series of complex and dynamic processes which occur in several stages. Optimal wound healing is essential for restoring the integrity and function of the affected area. Although medicated wound dressings have been extensively employed to control wound infection, the risks associated with antimicrobials make the use of non-medicated alternatives necessary. Nevertheless, the relationship between the concentrations of medicated wound dressings and their antimicrobial activities, along with their wound healing efficacies, still remains unclear. Non-medicated wound dressings are an alternative to dressings that contain active ingredients acting as antimicrobials or antiseptics. In the present study, the researchers examined the reduction of bacterial load as the primary endpoint and the healing rate as the secondary endpoint, comparing microporous ceramic dressings to silver-impregnated dressings in participants from two outpatient wound management clinics. The study included 25 participants in the silver-impregnated dressing (control) group and 28 participants in the ceramic dressing (study) group. The participants' wounds were assessed through MolecuLight i:X (MolecuLight Inc., Canada) wound tracing and MolecuLight i:X fluorescence imaging to measure the wound size, as well as presence of a bacterial load of >10⁴ colony forming units/g at weeks 1, 2, 3 and 4. The results indicated that there was a significant difference in the distribution over the categories of bacterial load cleared after weeks 1, 2, 3 or 4 in the two groups. Moreover, the bacterial load cleared significantly faster in the study group (p=0.001). Mean wound size was 10.93cm² (range: 0.10-37.95cm²) in the control group and 11.48cm² (range: 0.80-60cm²) in the study group. In the maximum likelihood regression analysis, the mean reduction in wound area for the study group was greater than that for the control group. The study concluded that the ceramic dressings could be an effective alternative to silver-impregnated dressings when treating infected wounds.</p>","PeriodicalId":17590,"journal":{"name":"Journal of wound care","volume":"33 12","pages":"898-904"},"PeriodicalIF":1.5,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142780609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2021, three individuals were evaluated at a single institution after developing frostbite while climbing Denali, Alaska, US. The affected patients were healthy men in the third to sixth decade of their lives, and all experienced frostbite injuries involving the fingers. Among the patients, one individual was unable to descend from the mountain due to the severity of his condition and required medical evacuation. The other men were able to descend without significant difficulty. After leaving the mountain, the patients were treated with thrombolysis, pentoxifylline, hyperbaric oxygen therapy, and/or regional sympathetic blockade. Exposure to cold weather, ascent to high altitudes, and increased mechanisms of heat loss were likely potential risk factors for frostbite injury in these patients.

Prevention is the most effective way to avoid frostbite, and knowledge and understanding of the risks associated with the development of this condition may reduce future occurrences among mountaineers.
