La mémoire de la bataille de Kulikovo dans l’idéologie de l’état russe des xve-xvie siècles

RésuméLa bataille de Kulikovo est aujourd’hui un « lieu de mémoire » classique de l’historiographie comme de la conscience collective russes. Pourtant, le rôle historique de cette victoire n’a pas été perçu immédiatement. Un siècle s’est écoulé avant qu’apparaisse le Dit sur la bataille contre Mamaj. Cette œuvre littéraire, qui correspondait pleinement aux priorités politiques des souverains russes des xve-xvie siècles, est pleine d’inexactitudes et d’anachronismes, dus aux nombreux emprunts faits par le compilateur. Ce récit mythique de la bataille se prêtait, bien mieux qu’un compte rendu prosaïque des faits, aux rites, anniversaires et célébrations consacrés au souvenir de l’exploit de Kulikovo.AbstractThe memory of the Kulikovo battle in the ideology of the Russian state in the fifteenth and sixteenth centuries.Today the battle on the field of Kulikovo is a classic “memorial site” for Russian historiography and collective consciousness. However, its historical significance was not immediately felt, and a century elapsed before the Story of the massacre of Mamai appeared. This literary work, which answered the political priorities of fifteenth- and sixteenth-century Russian rulers, abounds in inaccuracies and anachronisms resulting from the compiler’s numerous borrowings. This mythical tale lent itself much better to rites, anniversaries and celebrations held in the memory of the great victory at Kulikovo than any prosaic factual report

Fractional Carbon Dioxide Laser in Treatment of Acne Scars

BACKGROUND: Scars appear as a result of skin damage during the process of the skin healing. There are two types of acne scars, depending on whether there is a loss or accumulation of collagen: atrophic and hypertrophic. In 80-90% it comes to scars with loss of collagen compared to smaller number of hypertrophic scars and keloids.AIM: The aim of the study was to determine efficiency and safety of fractional carbon dioxide laser in the treatment of acne scars.MATERIAL AND METHODS: The study was carried out in Acibadem Sistina Clinical Hospital, Skopje at the Department of Dermatovenerology, with a total of 40 patients treated with fractional carbon dioxide laser (Lutronic eCO2). The study included patients with residual acne scars of a different type.RESULTS: Comedogenic and papular acne in our material were proportionately presented in 50% of cases, while the other half were the more severe clinical forms of acne - pustular inflammatory acne and nodulocystic acne that leave residual lesions in the form of second, third and fourth grade of scars.CONCLUSION: The experiences of our work confirm the world experiences that the best result with this method is achieved in dotted ice pick or V-shaped acne scars

Treatment of venous ulcers in drug addicts: A case report

Treatment of venous ulcers in drug addicts: A case report Mirela Vasileva Vesna Brishkoska Boshkovski Andrej Petrov Venous ulcers are common in drug addicts and, although the management of these wounds is the same as in other patients, there are differences in the approach and the outcome of treatment. Those injecting drugs are at risk of serious infections, such as necrotizing fasciitis, wound botulism, and cutaneous anthrax due to the nature of the substances being injected. Herein, we present two cases of venous ulcers in drug addicts in their thirties. Both patients had been suffering from a venous ulcer for several years and the final result differed in the two patients. We concluded that it is necessary to raise awareness of the importance of treatment and lifestyle changes. The multidisciplinary approach in these patients may contribute to the improvement of wound healing. 10 19 2021 439 441 10.7241/ourd.20214.21 http://www.odermatol.com/issue-in-html/2021-4-21-venous_ulcers

Landscape, Memory, Heritage and Identity (Historiographical Overview)

Introduction. UNESCOs adoption of the Convention “Concerning the Protection of the World Cultural and Natural Heritage” of 1972 led to the discussion on the issues of mutual influence and interdependence of humankind and nature and human perception of the environment and his own ecological niche. As a result of these discussions, the term “cultural landscape” came into use, and became part of the world cultural heritage. Methods and materials. This study is based on the combination of the general, special historical and cultural methods. The central place among them was occupied by the comparative, analytical, historical-genetic, comparative analysis methods and some methods of historical cultural studies. Analysis. The evolution of the cultural landscape took place throughout human history and is a unique blend of not only human development. It also reflects, on the one hand, national culture and mentality, and on the other, shows the influence of natural factors on their development. It also helps to understand the mentality of various ethnic groups, similarities and differences in their perception of the world and attitude. The development of the cultural landscape concept has become an integral part of the Anthropocene theory, based on the teachings of V.I. Vernadsky, about the impact and intersection of the geo-, bio- and noosphere in the fate of humankind. Results. The article considers the development of the “cultural landscape” theory mainly in English and American historiography which conclusively demonstrates how natural factors impact on changes in culture of the same ethnos. Through historiographic studies and comparisons, it becomes possible to trace the importance of preserving and studying the cultural landscapes of the past and present, in order to understand ourselves and be responsible to the world around us

Principles and methods for isolation and preparation of plasma preparations containing platelets (PR) - how to improve the purpose and effectiveness

The clinical use of platelet-rich plasma (PRP) is based on increasing the concentration of growth factors and the secretion of proteins that can maximize the healing process at the cellular level. PRP is an autologous biological material, that involves minimal risk of immune reactions and transmission of infectious and contagious diseases, and it is widely used to repair musculoskeletal lesions and skin. Despite the great potential for applicability, the implementation of therapeutic inclusion of PRP as a clinical alternative has become difficult due to the lack of studies related to the standardization of production techniques, application conditions, and/or insufficient description of the adopted procedures. Currently, platelet-rich plasma therapy (PRP) is widely used and continues to grow for a variety of clinical applications. Along with its development, there are various options in the way of obtaining PRP, automatic or manual, while one of the most reliable methods according to the literature is the method of double centrifugation. Therefore, it is necessary to establish standard criteria to be met to obtain high-quality PRP, as well as several studies to determine the appropriate platelet concentration for different clinical applications. In this context, this paper aims to discuss some methodological aspects used to obtain PRP, as well as to discuss the bioactive properties of PRP and to point out its therapeutic use in various fields of regenerative medicine. Additionally, current techniques, critical points, technology for PRP preparation, and a review of the present deficiencies of this therapy that will need to be overcome if widely accepted, are described

Comorbidities as Risk Factors for Acute and Recurrent Erysipelas

BACKGROUND: Erysipelas is a common infectious skin disease. A typical feature of erysipelas, especially on the lower limbs, is the tendency to reoccur and the study aimed to define the comorbidities associated with it. AIM: We aimed to investigate systemic and local comorbidities in patients diagnosed with erysipelas on the lower limbs. MATERIAL AND METHODS: We conducted a retrospectively-prospective, population-based cohort study which included all patients diagnosed with erysipelas on the lower limbs, during two years. Patients were divided into two groups: patients with first episode and patients with recurrent erysipelas. These two groups were compared, with particular emphasis on systemic and local comorbidities. RESULTS: The study included 313 patients, of which 187 with the first episode of erysipelas and 126 with a recurrent. Regarding the analyzed systemic risk factors, the recurrent erysipelas was significantly associated with obesity (p < 0.0001), insulin dependent diabetes mellitus (p = 0.0015), history of malignant disease (p = 0.02) and tonsillectomy (p = 0.000001). For a p-value < 0.0001, significantly more frequent finding of peripheral arterial occlusive disease, chronic oedema/lymphoedema, fungal infections of the affected leg and chronic ulcer was confirmed in recurrent erysipelas. Neuropathy had 23% of the recurrent cases and 8.6% in patients without recurrence, and the difference was found to be significant for p = 0.0003. The only dissection of the lymph nodes was found more frequently in recurrent erysipelas (p = 0.017), but no associations with other analysed local surgery on the affected leg. Patients with recurrent erysipelas had ipsilateral coexisting dermatitis p = 0.00003 significantly more frequent. Minor trauma often preceded the first episode of erysipelas p = 0.005. CONCLUSION: Identification and treatment of modifiable risk factors are expected to reduce the risk of a subsequent episode of erysipelas on the lower limb
