Jessner’s lymphocytic infiltrate of skin, reticular erythematous mucinosis and lupus tumidus are the group of rare, insufficiently explored dermatosis with common clinical and histological features, whose nosology is controversial today. Plasmacytoid dendritic cells play the key role in autoimmune disease induction The target of our study was the analysis of pathomorphological features of lesional skin and the research of plasmacytoid dendritic cells in the skin of patients with Jessner’s lymphocytic infiltrate of skin, reticular erythematous mucinosis and lupus tumidus. Material and methods. Histological and indirect immunohistochemistry examination (anti-CD123 antibodies) of lesional skin of 36 patients was held (JLIS - 12, REM - 10, LT - 14) and 10 healthy people. Result. The main pathomorphological changes of skin in all groups were found in dermis: dense perivascular and perifollicular infiltration and deposit of mucin between collagen fibers. Deposits of mucin in papillary dermis were found between patients with JLIS, REM and LT in 10/12 (83%), 7/10 (70%) and 12/14 (86%) of cases, there were no mucin found in skin of healthy people 0/10 (0%) In all dermatosis the distribution of CD123 cells in lesional skin, in immunohistochemistry study, was corresponded clusters model of infiltrate - plasmacytoid DC concentrate in groups around vessels of superficial and profundus networks and perivascular. The comparative analysis of density and localization of perivascular infiltration, number of CD123-cells and their correspondence in dermis perivascular infiltrates didn’t reveal statistically significant differences between JLIS, REM and LT. Results. Our results allow us to consider JLIS and LT as identical decease, and REM as similar in clinical-pathomorphological features dermatosis.

Describes a rare clinical case demonstrating the sudden appearance of the disease Sneddon - Wilkinson in women during pregnancy, which regressed completely within a month after birth and had no recurrence.

Atopic dermatitis (AD) is a common skin condition treated by dermatologists all over the world. Guidelines for management and treatment of AD have appeared in Europe, USA and Russia recently. the paper contains comparison of European, American and Russian guidelines. Definition of AD, epidemiology, pathophysiology of the disease, clinical features, diagnostic criteria, and risk factors are consistently matched. the analysis demonstrated that guidelines do not contain serious contradictions and principal differences thus stressing their supplementation of each other.

Clinical presentation is given of eruption in the case of segmental vitiligo and nevus achromicus. Literary data was presented, issues of differential diagnostics were discussed.

Objective. To estimate efficiency and safety of application of a preparation of Aldara (imiquimod, 5% external application cream) it is independent or in combination with cryotherapy in therapy of the basal cell carcinoma of the skin (BCC). Material and methods. Research included 78 patients (22 women and 56 men) with various forms of a basal cell carcinoma of the skin. All patients were divided into 3 groups: the main group (n = 30) the patients receiving therapy by Aldara (imiquimod, 5% external application cream) made, second (n = 21) - the patients receiving therapy by Aldara’s, and also 1 course of cryotherapy, and the group of comparison (n = 27) receiving therapy of placebo in the form of external application cream. Therapy was carried out 3 times a week, within 16 weeks. Research was conducted in some stages with histologic confirmation of the diagnosis, and also an assessment of efficiency of therapy and undesirable effects. Results. At 27 of 30 patients of the first group (90%) and at 21 of 21 patients of the second group (100%) receiving treatment by Aldara’s absolute clinical recovery is reached. In group of comparison of clinical recovery at all 27 patients it wasn’t observed. It is expedient to note that at all patients of the second group (100%) already to 75 ± to the 2nd day of therapy (the 4th visit) clinical recovery while at 27 of 30 patients of the first group (90%) the total disappearance (clinical recovery) came for 105 and more days (the 5th and 6th visits) was noted. Recurrence of a disease after the end of therapy it wasn’t observed. Conclusion. Aldara (imiquimod, 5% external application cream) possesses high efficiency at therapy of various forms and sizes of BCC. Undesirable effects of therapy are easily resolved at cancellation of a preparation and not observed at its renewal. Unlike other immunomodulatory preparations (corticosteroids, retinoid, cyclosporin) Aldar’s application doesn’t promote suppression of cellular immunity.

Leprosy (Hansen’s disease) is a chronic granulomatous bacterial disease which mainly affects skin and peripheral nervous system. Leprosy is caused by the obligate intercellular pathogen known as Mycobacterium leprae. Creating experimental models of leprosy is associated with serious problems due to biological characteristics of the pathogen. Numerous attempts to develop experimental models on different types of animals resulted in a few reproducible models on mice and nine-banded armadillos. Strains of knockout mice with genetic defects caused by site-directed mutagenesis are used as a basis for different leprosy models. Experimental models of leprosy are used for screening of anti-leprosy drugs, detection of drug resistance, studies on the pathogenesis of leprosy, production and evaluation of viability of M. leprae, developing of anti-leprosy vaccines.

The review deals with up-to-date genotyping assay methods of Neisseria gonorrhoeae. The review covers the characteristics and features of each method, application areas of genotyping assay of Neisseria gonorrhoeae. The methods described enable to upgrade the diagnostication of gonococcal infection, predict its antibiotic resistance, trace the contagion and channels of the infection as well as study the processes of molecular evolution of the microorganism. Information obtained based on up-to-date N. gonorrhoeae genotyping assay methods can be used in developing the reproductive health strategy of the population.
