[Use of mildronate in therapy of seroresistant syphilis (serologic and immunologic comparisons].

Clinico-serological and immunological examinations were applied to 84 patients suffering from seroresistant syphilis with positive serological reactions within 1.5 to 10 years after termination of the treatment by various methods. The initial diagnosis of recently inflicted secondary syphilis was recorded in 8.

[Actinic reticuloid].

A patient with a rare dermatosis, actinic reticuloid, is described. Differential diagnostic characteristics of this condition as against mycosis fungoides are presented, and rational therapy of such patients is discussed.

[Rowell's syndrome].

Two cases with this rare syndrome are described, with a combination of lupus erythematosus and erythema multiforme exudativum.

[Skin leiomyomas].

Three patients with multiple leiomyomas of the skin were treated with electro-excision techniques. The tumor was hereditary in one of these patients.

[The localization of structurally specific antigens in squamous cell skin cancer using monoclonal antibodies to epidermal antigens].

Immunomorphological studies by indirect immunofluorescent method using monoclonal antibodies to antigens of basal cells, suprabasal cells and basal membrane of the epidermis were carried out in 8 cases of squamous-cell skin cancer. Specific characteristics of localization of structure-specific antigens (as compared with normal human skin) in squamous-cell skin cancer are discussed.

[Detection of a cross-reacting antigen common to multilaminar epithelia and group A streptococcus in cells of human epidermal tumors].

The tissue-specific antigen of basal cells of human squamous epithelium which cross-reacts with streptococcal group A antigen has been detected in the cytoplasm of cells of human basal cell and squamous cells carcinomas histogenetically related to the skin epithelium. The antigen has not been detected in cells of tumors of endodermal origin (gastric and intestinal adenocarcinomas). These findings together with previous reports on the existence of cross-reactivity in case of animal tumors of ectodermal genesis may form the basis for an additional method of differential diagnosis of human tumors arising from the ectoderm-derived epithelium.
