“…[11][12][13][14][15] It has also been shown that dermatologic diseases like systemic sclerosis and psoriasis, and also some therapeutic approaches such as radiotherapy, can alter skin thickness. 2,3,16 However, to our knowledge, our report is the first to focus on skin thickness over bony prominences among a wheelchair-user population.…”

Objective: The detailed assessment of soft tissues over bony prominences and identification of methods of predicting pressure sores would improve the quality of care for patients with spinal cord injury (SCI). Comparing skin thicknesses on bony prominences in patients with SCI to those in healthy individuals will represent, to our knowledge, the first study aimed at determining whether differences in skin thicknesses between these groups can be detected by ultrasound. Design: In both patients and controls, skin thicknesses on the sites at risk for pressure ulcers -sacrum, greater trochanter, and ischium -were evaluated using high-frequency ultrasound. The waist was also evaluated by the same method for control as it was considered to be a pressure-free region. Participants: Thirty-two patients with complete thoracic SCI and 34 able-bodied individuals. Results: The skin was significantly thinner over the sacrum and ischial tuberosity in individuals with SCI compared with healthy individuals. No significant differences were observed in skin thicknesses over the greater trochanter or the waist between the two groups. Conclusions: Protecting skin integrity in patients with paraplegia is challenging due to many contributing factors, such as prolonged pressure, frictional/shearing forces, and poor nutrition. Thinning of the skin can increase the risk of soft tissue damage, leading to pressure ulcers. The significant differences in skin thickness at the sacrum and ischium provide the basis for establishing the early signs of pressure damage. Measuring skin thickness by ultrasound is a reliable non-invasive method that could be a promising tool for predicting pressure ulcers.

“…There has also been a third factor, i.e. the technical factors limiting image resolution (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). It is often necessary to visualise sub-centimeter lesions or even smaller, as in the case when measuring the thickness of a melanoma, and this cannot be achieved using traditional 7-10 MHz ultrasound.…”

“…Conditions, which compromise this network, cause low echogenicity and reflect, for example, subepidermal increase of interstitial fluid in oedema. 13 High frequency ultrasound has been used in several skin diseases 14 but only in limited amounts in localised 15 and systemic scleroderma. [16][17][18][19] This report examines the performance of a standardised high frequency ultrasound protocol in longitudinal observations of patients with early phases of both types of SSc.…”

Background: Measurement of skin involvement is essential for diagnosis and prognosis in systemic sclerosis. Assessment by palpation skin score is the current method. Objective: To explore high frequency ultrasound as an objective method to improve skin characterisation by combining measurements of skin thickness and echogenicity. Methods: Skin thickness and echogenicity were measured at the proximal phalanx of the second digit, the back of the hand, the forearm, and the lower leg and, in order to separate limited (lSSc) from diffuse SSc (dSSc), at the chest in 16 patients with early disease and in 16 controls. Measurements were repeated in each patient three or four times with an interval of 1-2 years. Ultrasound measurements of skin thickness were compared with the palpation skin score. Results: Compared with controls, the skin was thickened on the phalanx, hand, forearm, and chest of patients with dSSc, but not patients with lSSc, at the 1 year examination. In dSSc the degree of thickening tended to diminish with time, and at 4 years, thickness was significantly decreased on the forearm and chest compared with the 1 year measurements. Low reflectancy was most pronounced at the 1 year evaluation on the forearm, hand, and phalanx in dSSc, and on the phalanx in lSSc. Conclusion: Separate measurements of skin thickness and echogenicity by high frequency ultrasound add a new dimension to the assessment of skin involvement in SSc, and this seems to be an objective noninvasive tool for use in the study of disease development and in clinical trials.
