[Psychodermatology: current state of the problem].

An analysis of comorbidity of psychiatric and dermatological pathology in historical, epidemiological and clinical aspects is presented. Psychocutaneous disorders (delusional parasitosis, hypochondria circumscripta, obsessive-compulsive disorders with self-mutilations, pathomimia) play a central role in systematics elaborated in the present study. The authors suggest that delusional parasitosis is a subtype of paranoiac psychosis (paranoia, paranoiac schizophrenia). Psychiatric disorders triggered by dermatological pathology were specified as nosogenous reactions, depressive reactions with sociophobia, pathologic personality development (paranoiac, sensitive, hypochondriac). Atopic dermatitis, eczema, urticaria, psoriasis, herpes simplex, alopecia areata, rosacea, etc, are regarded among dermatological psychosomatic disorders with psychogenic manifestation/exacerbation.

[Proliferative activity of peripheral blood lymphocytes and evaluation of the effectiveness of drugs in lichen ruber planus].

A total of 106 patients with lichen planus were examined for proliferative activity of peripheral blood lymphocytes and exogenous interleukin-2 effect on recovery of cyclosporin A suppressed proliferative response to mitogen. Lymphocyte proliferative activity was assessed by the level of 3H thymidine incorporation in cellular DNA. This parameter was found reduced in patients with lichen planus in comparison with healthy donors and dependent on the disease stage but not degree of dissemination. No disorders were detected in lymphocyte capacity to express receptors for interleukin-2 in the course of their activation. Tigason, prednisolone, and delagil had a marked in vitro antiproliferative effect on the lymphocytes of patients with lichen planus, tigason exerting the highest effect and prednisolone the lowest.

[Clinical significance of hyperuricemia in psoriasis].

After analysis of 1146 psoriasis patients, high incidence of asymptomatic hyperuricemia (18.8%) and elevated average levels of uric acid in these patients' blood were confirmed (346.8 +/- 2.4 mumol/l). More severe forms of uric acid disbolism lead to aggravated skin affections (psoriatic erythrodermia, exudative psoriasis), arthritis, occur in familial predisposition to psoriasis. Advanced psoriasis patients are at risk to develop apparent gout.

[Role of herpes simplex virus in the development of exudative erythema multiforme].

The paper presents analysis of current knowledge on etiology and immunopathogenesis of multiform exudative erythema (MEE). Among a variety of pathogenetic actions of herpes simplex on immune system are those relevant to MEE onset. These variants are dealt with in detail. The view on MEE as resultant from herpes simplex infection promises appearance of new prospective modes of etiotropic therapy.

[Blood coagulation in angiitis of the skin].

Basing on the studies of coagulograms of 88 patients with skin angiitis, the authors analyze the hemocoagulation status in this condition. A shift towards blood hypercoagulation in the presence of fibrinolysis reduction was found to contribute to the pathogenesis of skin angiitis, this fact should be borne in mind when planning combined therapy of such patients.

[Experience with a combined test exam in dermatovenereology].

The traditional oral examination in clinical dermatology is not devoid of shortcomings, the principal of which are subjective estimation of the students' knowledge and a random control. A written examination, representing a complex of tests, is devoid of these drawbacks. The authors share their two-year experience with such examinations, combined with the control of mastering the practical skills in dermatology and venereology. The major advantages of a written test-based examination in a clinical discipline are an objective estimation of the students' knowledge, a universal complex of tests equally difficult for all the students, permitting the control of knowledge in practically all sections of the curriculum, and a more rational organization of the examination session. Such examinations are recommended for dermatology and venereology chairs.
