Background/aim: Nailfold video capillaroscopy is considered as a reliable method for evaluating peripheral microangiopathy in rheumatologic diseases. In this study, we aimed to demonstrate the utility of handheld dermatoscopy as an easy-to-use nailfold capillaroscopic instrument in patients with rheumatoid arthritis.Materials and methods: This cross-sectional study included patients with rheumatoid arthritis and healthy subjects. A handheld dermatoscopic examination of proximal nail fold was performed in each subject. The possible correlation of capillaroscopic findings with disease activity was evaluated using the disease activity score 28 (DAS28).Results: A total of 59 patients with rheumatoid arthritis and 60 healthy subjects were enrolled in the study. The presence of capillaryenlargement, avascular areas, capillary deformities, and capillary vascular anomalies in the group of patients showed a statistically significant difference when compared with the healthy subjects. No correlation was found between the nail fold capillaroscopic findings and DAS28 score.Conclusion: Hand-held dermatoscopy seems to be a useful technique in the evaluation of nail fold capillary changes. We suggest that in patients with rheumatoid arthritis, when capillaroscopic examination is needed, it can be evaluated using handheld dermatoscopy. Selected patients who showed findings using this method can be further examined with classical capillaroscopy to obtain more quantitative data.

The authors present a review of up-to-date non-invasive visualization methods used in diagnostics of diseases of skin and its appendages. They describe physical principles forming the basis for non-invasive visualization methods such as dermatoscopy, confocal laser scanning microscopy, optical video monitoring, optical topometry, optical coherent tomography, ultrasound scanning, 3D-modeling. They also describe the potential of practical application of these diagnostics methods at the current stage of their development. The authors have demonstrated that it is possible to reduce the clinicians need in biopsy diagnostics due to the high information value of non-invasive visual diagnostics methods.

The results of the study of biorevitalization effectiveness of the facial skin in women aged 30 to 40 years are presented. Material and methods. In the 1st group (n = 30) hyaluronic acid (HA) was used along the face oval, in the zone of the cheekbone, along the nasolabial folds, along the longitudinal wrinkles in the forehead area with the use of “micro-puncture” and “short-linear” techniques in the medium-deep layers of the dermis. The distance between injections is 1 cm. Injection schemes are standard, proposed by manufacturing companies - once a week, in total 6 procedures. In group 2 (n = 30), the HA was administered with the Legato apparatus, where two technologies were successively used: radio frequency and ultrasound, once every 2 weeks, with a course of 5-6 procedures. Both groups used HA in a concentration of 2 mg/ml Gialripyer-07M/mesolift. Instrumental studies of the functional properties of the skin included assessment of hydration of the epidermis (corneometry), deformation and elastic properties of the skin (cutometry), assessment of transepidermal loss of moisture (TEVA-metry), assessment of seboregulatory function of the epidermis (sebometry) using Multi Skin Test Center® MC750; dermatoscopy on a digital video camera Aramo SG, providing a computer image of the texture of the skin and its moisture level; ultrasound scanning of the skin using a digital high-definition system DUB (“TPM GmbH”, Germany) and a high-frequency linear 17 MHz sensor in SmParts Superfic scanning mode with a resolution of 78 microns. Results. The study shows the superficial effect of mesotherapy procedures: improving the morphofunctional properties of the skin, they have no effect on the thickness, echogenicity and relief of the dermis. At the same time, the obtained results of instrumental studies of the structural and functional parameters of the skin make it possible to justify the use of modern technology Legato (radio frequency and ultrasound) for intradermal administration of HA preparations, with the help of which it is possible to obtain in a short time a positive dynamics of the indices of structural and functional parameters of not only surface layers of skin, but also at the level of the dermis.

Introduction. Burns of various etiologies are on the 3-4 place in frequency among all injuries, they are associated with a high percentage of complications, disability and mortality. Currently, a single algorithm for objective verification of the depth of skin damage has not been developed. Numerous diagnostic technologies used to solve this problem require systemic analysis.The aim of study was to analyze current literature data on technologies for instrumental diagnostics of the depth of thermal damage to the skin.Materials and methods. A search for literary sources in databases was conducted using eLIBRARY.RU, PubMed, Cyberleninka databases. The period of publications was limited to 2011-2020.Results. The method of objective "gold standard" verification of thermal damage to the skin remains a biopsy followed by morphological examination, but the method's traumaticity does not allow it to be used for monitoring the course of the process in dynamics, for multi-focal studies. Among non-invasive methods, dermatoscopy and video microscopy are noted, but the small imaging area and the need for direct contact of the device with the skin surface limit the use of these methods. Laser Doppler flowmetry and imaging are fairly accurate non-contact methods that allow assessing the condition of a burn wound in real time. The method is not applicable to wounds with blisters, insufficient sanitation. Laser speckle contrast imaging is used to evaluate blood flow and is based on the analysis of speckle structure fluctuations. The method allows determining the degree of burn damage depending on changes in the blood flow. However, the method is difficult to apply with a vessel diameter sized 40 microns. The method is sensitive to movement and internal factors. Infrared and Raman spectroscopy are technique for evaluating vibrational patterns in a particular spectrum, these can be used to identify a molecule or determine its structure. Simultaneous use of spatial frequency visualization and speckle imaging demonstrated a high level of correlation with the results of histological research, which makes the use of these methods promising. Ultrasound also provides a proper correlation with histological data, but it is an imperfect method due to inaccuracies in determining the thickness of the epidermis, dermis, and scar condition. Optical coherence tomography (OCT) is a non-invasive optical method that allows obtaining high-resolution images of skin architecture in real time. The high level of compliance of the visualized structures, in particular, layers, appendages and vessels of the skin, with histological findings, gave this method a name "optical biopsy". Anatomical congruence of normal and damaged skin was established in an experiment between histology and OCT.Conclusion. Early assessment of the depth of thermal damage to the skin is crucial for choosing a personalized treatment strategy for the burned. None of the modern diagnostic methods is universal. Multimodal approaches to diagnostics are the most effective.

The work is devoted to the development of an automated system for video dermatoscopy. The main approaches in the design of such systems, methodological support and structural modules are considered. The main stages of the digital processing of dermatoscopic images are proposed. The main focus is on the methods of automated segmentation of dermatoscopy images and the analysis of the errors that arise. The processing of heterogeneous medical data requires an integrated approach aimed at developing complete specialized diagnostic systems taking into account the specifics of a particular area and the nature of the images obtained. The stages of preprocessing, segmentation, description, and analysis of digital dermatoscopy images are considered in detail related to each other. The diagnostic capabilities of the digital dermatoscopy method are discussed. The main aspects of the automated analysis of the processing of dermatoscopic images and the prospects for the use of such systems in medical practice are considered.
