[Difficulties in the diagnosis of chronic toxoplasmosis with lung involvement]. / Trudnosti diagnostiki khronicheskogo toksoplazmoza s porazheniem legkikh.

A case of chronic acquired toxoplasmosis combined with lung impairment is described. The diagnosis was made on the basis of the data obtained as a result of the use of the latest clinical and instrumental research methods and a specific serologic test. The diagnosis was verified morphologically on thin sections of the sputum. The authors provide data on the diagnostic search for approaches to the differentiation between parasitic diseases resulting in dissemination to the lungs with calcification of the foci and broncholithiasis, tuberculosis.

[Echocardiographic diagnosis of the mitral valve cusp flotation syndrome]. / Ekhokardiograficheskaia diagnostika sindroma flotatsii stvorok mitral'nogo kaplana.

The flotation of the mitral cusps is one of the forms of non-rheumatic mitral regurgitation due to disorders in the chordal fixation of the cusps. The authors have examined 26 patients with echocardiographic signs of flotation of the anterior or posterior mitral cusps. In 21 patients there was flotation of the posterior cusp and 5 had flotation of both the cusps. The comparative diagnostic value of separate echocardiographic signs of flotation of the anterior and posterior cusps of the mitral valve is discussed. It is stressed that echocardiography is a valuable method of investigation.
