The idea of CLA+T-lymphocytes, which are a special subpopulation of cells with a tropic to the skin, is given. The issues of maturation, migration and functional features of CLA+T-cells are considered. Special attention is paid to the different phenotype of memory T-cells. Modern data concerning the role of CLA+T-cells in the pathogenesis of autoimmune and allergic dermatoses, as well as malignant skin tumors are also presented. The conclusion about the necessity of further study of CLA +T-lymphocytes for detailed understanding of pathogenesis and search of variants of targeted therapy in psoriasis, atopic dermatitis, skin lymphomas and other skin diseases is made.

This paper presents the results of a retrospective epidemiological study carried out to detect chronic infection foci (CIF) in patients affected by T-cell mediated dermatoses. The values obtained for the CIF prevalence are compared with those in the general population, as well as in the control group. The latter comprised generally healthy people according to the results of in-depth medical examination. It is found that patients with psoriasis demonstrate a higher prevalence of chronic tonsillitis compared to the values both in the general population and in the control group (p = 0.001). Patients with eczema are characterized by an increased prevalence of chronic granulomatous periodontitis, but only in comparison with generally healthy individuals (p = 0.046). The results obtained for patients with atopic dermatitis, lichen planus and alopecia areata are found to be statistically significant for chronic tonsillitis, which occurs therein more frequently than in the general population and in the group of generally healthy people (p = 0.001).

Aim. The aim of this study was to examine the dermatoscopic signs of nevus sebaceous in its different age periods.

Materials and methods. The study sample included 49 patients diagnosed with nevus sebaceus of Ja dassohn, seeking medical assistance in the Ryazan Region Clinical Dermatological and Venerealogical Dispensary during the 2014–2018 period. The age of the patients ranged from 1 month to 69 years.

Results. The study describes the main dermatoscopic manifestations of nevus sebaceous of Jadassohn in its different age periods.

Conclusions. The results of the study are significant for the differential diagnostics of nevus sebaceous of Jadassohn.

The therapeutic effects of synthetic tannins are based on their binding action, as well as on their anti-pruritic, antimicrobial and anti-inflammatory effects. Materials and methods. A clinical study of Neotanin spray, Neotanin lotion (suspension) and Neotanin cream was carried out in 8 clinical centres during the period from June, 2017 to January, 2018. The study had an open and non-comparative character. The study included 68 patients of both sex es aged from 1 month to 80 years suffering from eczema dermatosis in the acute weeping phase, including cases with complications after secondary infections (including eczema elements localized on the face). Before the study, information on the clinical history, demographic data, co-morbidities, physical examination data of the patients was collected. The treatment regimen included 2 stages: 1) Neotanin in the spray or lotion (suspension) form 3–4 times per day during 1–5 days, up to the full drying of eczema elements; 2) Neotanin in the cream form 3 times per day, up to the disappearance of the clinical manifestations of skin dermatosis. The duration of the study ranged from 5 to 14 days: the study was completed when a patient had achieved remission. The criteria for assessing the drug efficacy were as follows: dynamics of subjective complaints, objective assessment of the patient's condition (the presence and severity of clinical symptoms), dynamics of the Dermatology Life Quality Index (DLQI). Results. Neotanin preparations showed a high efficacy in the acute and subacute stages of the inflammatory process as an antipruritic agent. Itching stopped within 5 minutes after the drug application, with the antipruritic effect lasting for an average of 3–4 hours. In 85 % of the patients, marked excoriations were absent on the 3rd day of treatment. Neotanin demonstrated a pronounced anti-inflammatory effect. In 92 % of the patients, the symptoms of erythema and edema were significantly reduced one week after the beginning of treatment, with the manifestations of inflammatory exudation being conclusively decreased. One week following the beginning of treatment, 100 % of the patients demonstrated no oozing lesions. The absence of serious undesirable effects in the patients during the study evidences to the good tolerability and safety of this drug.

Mucosis fungoidea (МF) belongs to the class of epidermotropic T-cell lymphomas. MF is represented by over 10 sub-types only in terms of its clinical manifestations, with one of them being erythrodermic MF (EMF). This disease is characterized by diverse symptomatology in the form of erythroderma and intense skin itch, aggressive сlinical course and unfavorable prognosis. The disease prognosis also correlates with age, previous history of long-term systemic gluco-corticosteroid treatment (GCS), increased activity of lactate dehydrogenase (LDH) and hypereosinophilia. The choice of MF treatment is determined by the disease stage and somatic status of the patient. In EMF, a therapy combining various effective preparations and taking into account the specifics of the given case is required. Extracorporeal photopheresis (ECP) is frequently an approach of choice; however, it has demonstrated the highest efficacy in Sezary disease or in EFM associated with leucemization. Application of new pharmaceuticals (monoclonal antibodies, epigenetic agents) in combination or in sequence with immune therapy is a promising direction, particularly for treating patients older than 75 years. In this paper, we describe the clinical case of an elderly patient suffering from EMF without peripheral blood leukemia with multimodal factors of unfavorable prognosis, such as age, increased lactate dehy drogenase activity, history of prolonged inefficient treatment with gluco-cortecosteroid preparations and eosinophilia. A long-term positive response to the treatment using sequential immune epigenetic therapy has not been achieved, although the treatment tolerability and the patient's life quality were satisfactory.

In article presents the results a comparative analysis of the prevalence and incidence of the skin and subcutaneous tissue diseases in the railway transport workers of the Altay region, of the West-Siberian Railways, of JSC Russian Railways and the local population of the Siberian Federal district, and the Russian Federation.
