[The classification of pneumoconioses]. / O klassifikatsii pnevmokoniozov.

The article deals with analysis of scientific data concerning etiology, pathogenesis, clinical and roentgenologic manifestations, morphologic appearances and other aspects to precise and refine the former idea of pneumoconioses. The authors present the main principles for improved classification of pneumoconioses.

[Current diagnostic problems of occupational diseases of the respiratory organs from exposure to industrial aerosols]. / Aktual'nye voprosy diagnostiki professional'nykh zabolevanii organov dykhaniia ot vozdeistviia promyshlennykh aérozolei.

Occupational respiratory diseases due to industrial aerosols pertain to one of the most prevalent forms of occupational pathology. The experience of many years gained by the clinic of our Institute enables one to define the significance of some forms of the given pathology and characteristic features of their diagnosis. The broad-scale introduction into the clinical practice of intravital biopsy of the lungs requires the solution of the problem as to whether the given method equally to the x-ray technique regarded as the basic one is of informative value for the diagnosis of pneumoconiosis. The diversity of occupational pulmonary diseases which are due to industrial aerosols and differ in the pathogenesis and clinical manifestations determines the importance of perfecting the clinical groupings of the main forms of occupational diseases in terms of the pathogenesis.

[Morphogenesis of emphysema in occupational lung diseases (clinico-anatomical comparisons)]. / K morfogenezu emfizemy pri professional'nykh zabolevaniiakh legkikh (kliniko-anatomicheskie sopostavleniia).

The distinction of pneumoconiosis and occupational (dust) bronchites in the clinic of occupational lung pathology required morphological justification of such divisions. Examinations of 37 fatal cases with dust pathology of the lungs showed that in two thirds of the cases predominantly obstructive bronchitis forms of emphysema and compensatory perinodular forms of emphysema in silicosis could be diagnosed morphologically. A less marked diffuse character of emphysema in focal forms of pneumoconiosis is conducive to the inclusion of compensatory mechanisms preventing the development of pneumonial and cardial insufficiency.
