title: [Pathologic anatomy and pathogenesis of focal pneumonias in mental patients of late middle and advanced age].
abstract: The author studied 128 postmortem cases with focal pneumonia in mental patients (74 cases) and normals (54 control cases) at old age. In the main group there was a significant lesion of the bronchial tree, a polysegmental nature of pneumonia with a frequent localization of the process in the 10, 9, 6 and 2 segments of the lungs, expressed changes in the fibrillar structures, a drop in the immunological reactivity, atypical clinical development. Pneumonia in old age and especially in mental patients has an important thanatogenetical significance. In its pathogenesis special attention should be paid to the state of defensive mechanisms in respiratory organs, to the etiology of pneumonia and the level of immunological reactivity in such patients.
