“…Determining the margin of the wounds is sometimes difficult, especially during later days when scabs start to develop. Moreover, photography only assesses healing at the surface level, whereas areas deep within the wound are equally important for the healing process (Dyson et al 2003). However, TEWL was our primary outcome and there was good concordance between these assessments.…”

The effect of Mindfulness-Based Stress Reduction on wound healing: a preliminary study

Psychological factors have been shown to influence the process of wound healing. This study examined the effect of Mindfulness-Based Stress Reduction (MBSR) on the speed of wound healing. The local production of pro-inflammatory cytokines and growth factors was studied as potential underlying mechanism. Forty-nine adults were randomly allocated to a waiting-list control group (n = 26) or an 8-week MBSR group (n = 23). Preand post-intervention/waiting period assessment for both groups consisted of questionnaires. Standardized skin wounds were induced on the forearm using a suction blister method. Primary outcomes were skin permeability and reduction in wound size monitored once a day at day 3, 4, 5, 6, 7, and 10 after injury. Secondary outcomes were cytokines and growth factors and were measured in wound exudates obtained at 3, 6, and 22 h after wounding. Although there was no overall condition effect on skin permeability or wound size, post hoc analyses indicated that larger increases in mindfulness were related to greater reductions in skin permeability 3 and 4 days after wound induction. In addition, MBSR was associated with lower levels of interleukin (IL)-8 and placental growth factor in the wound fluid 22 h after wound induction. These outcomes suggest that increasing mindfulness by MBSR might

“…Since HFU allows sequential tissue monitoring, these previous authors suggested that it could be used to discriminate between healing and nonhealing chronic wounds, allowing for investigation of deep tissues without tissue biopsy [8]. Dyson et al discussed that the wound region may be more effectively measured by HFU than photography [9]. Wendelken et al monitored wound dimensions by filling the wound cavity with a sterile wound mapping gel and covering it with film dressing.…”

“…Using HFU to detect the early stages of pressure ulcer generation revealed that subdermal tissue and skin edema could be identified before any clinical or skin breakdown signs were seen [11]. Changes in tissue regularity and homogeneity during the healing process have also been observed using HFU [7][8][9][12][13].…”

“…High-frequency ultrasound (HFU) is an alternative method for evaluating wounds, including burn scars, surgery wounds, and pressure ulcers, and has been shown to be comparable or better at wound assessment than the aforementioned methods [5][6][7][8][9][10][11]. Rippon et al used artificially induced acute wounds in pigs to demonstrate that HFU and histology are comparable in their ability to reveal the dominant wound healing phenomena (e.g., wound depth, eschar/blood clot depth, collagen accumulation, and granulation tissue depth) [7].…”

Abstract-This article focuses on the development of a method to quantitatively assess the healing process of artificially induced pressure sores using high-frequency (20 MHz) ultrasound images. We induced sores in guinea pigs and monitored predefined regions on days 3, 7, 14, and 21 after sore generation. We extracted relevant parameters regarding the tissue echographic structure and attenuation properties. We examined tissue healing by defining a healing function that used the extracted parameters. We verified the significance of the extracted features by using analysis of variance and multiple comparison tests. The features displayed ascending/descending behavior during wound generation and reverse behavior during healing. We optimized the parameters of our healing function by using a pattern search method. We tested the efficiency of the optimized values by calculating the healing function value on assessment days and then comparing these results with the expected pattern of changes in the tissue conditions after removing the applied pressure. The results of this study suggest that the methodology developed may be a viable tool for quantitative assessment of pressure sores during their early generation as well as during healing stages.

“…Cutaneous ultrasonography has been extensively used in human dermatology to study normal skin echogenicity, thickness and hydration status, as well as various pathologic conditions, including cutaneous or subcutaneous neoplasms, cysts, inflammatory lesions, post-radiation reactions, scleroderma, edema, wounds, and presence of foreign bodies (Alexander and Miller 1979;Miyauchi and Miki 1983;Fornage and Deshayes 1986;Fornage et al 1993;Fornage 1993;Gniadecka 1996;Gniadecka and Quistorff 1996;Warszawski et al 1997;Milner et al 1997;Cammarota et al 1998;Foster et al 2000;Eisenbeiss et al 2001;Mirpuri et al 2001;Dyson et al 2003;Scope and Halpern 2003;Kong et al 2008). Contrary to the situation in human medicine, in veterinary medicine only few studies on cutaneous ultrasonography of the canine skin are available (Diana et al 2004;Mantis et al 2005;Mantis et al 2007;Diana et al 2008;Zanna et al 2012;Mantis et al 2014).…”

ABSTRACT. Real time B-mode ultrasonography is a non-invasive diagnostic imaging modality that does not use radiation and allows examination of various soft tissue structures. For many years it is used in human dermatology and in the last decade it has entered the canine dermatology arena. Based on the frequency employed, cutaneous ultrasonography may be classified as intermediate-(7-15 MHz) or high-frequency (20 MHz or higher). Using intermediate frequency, the ultrasonographic features of normal canine skin are consistent and three distinct visible layers can be seen. Using a 50 MHz transducer, the epidermis and hair follicles are also identified and accurate measurements of skin thickness can be obtained. The aim of this article is to review the available published knowledge regarding ultrasonographic examination of the canine skin.
