[Differences in the elastic work of breathing of the pulmonary parenchyma in patients with bronchial asthma and COPD].

Aim: To determine and compare the work of breathing to overcome elastic resistance (Ael) in patients with bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD) with similar changes in the elastic properties of the parenchyma in the same settings of ventilation disorders (grade 1).

Materials And Methods: Differences in the manifestations of similar changes in the elastic properties of the lungs in patients with BA and COPD were evaluated. To identify differences, a comparative study was conducted on Аel overcome in BA patients with positive bronchodilator (with salbutamol) and bronchoconstrictor (with methacholine) tests, with reduced and preserved bronchial conductance (groups 1 and 2, respectively), and in COPD patients with negative bronchodilator and bronchoconstrictor tests (group 3).

[Main directions of differential diagnosis optimization and rational treatment of an acute vertigo attack].

Aim: To develop and assess the validity of the clinical algorithm VERTIGO for the differential diagnosis of central and peripheral vertigo and optimization of treatment of patients with vertigo.

Material And Methods: Sixty-five patients with an acute attack of vertigo, aged from 18 to 75 years (53±6.7 years), were studied.

[Theoretical and practical aspects of treatment and prevention of acute cerebral blood cerculation disorders].

Stroke is an important medical and social problem. Views about etiology, pathogenetic mechanisms and therapy of patients with stroke have undergone significant changes. In this work, we elucidate contemporary theoretical and practical aspects of stroke treatment and prevention based on the results of multicenter clinical trials and experience of leading foreign and native specialists.

[Possibilities for the improvement of the quality of knowledge and their evaluation in the course of studying clinical medicine].

The authors consider objective and subjective factors exerting negative influence on the quality of knowledge of physicians. The generally accepted methods for its evaluation (testing and rating-systems) have limitations. Testing reflects the level of knowledge with respect to the mode of thinking of its designer while rating mostly characterizes diligence of the trainee.
