The same regularities of Metapathia hunter-picture

http://www.metapathia-hunter.com

Acute purulent processes are characterized by smaller than gangrenous abscesses size, often insufficient spontaneous drainage with heterogeneous diffuse distribution of achromogenic inclusions of air against isochromogenic background, absence of walls and sequesters. At adequate treatment we detected a positive dynamics in form of abscess cavity decreasing with simultaneous decreasing of fluid content amount and replacing by air. Further on a cicatrix was formed at the spot.
Chronic lung abscesses are characterized by the same regularities of Metapathia hunter-picture as acute ones. Diagnostic criteria are the quantitative ratio of purulent exudate and achromogenic air inclusions and their spatial distribution in a cavity. We singled out 4 types of chronic abscess depending on efficiency of its spontaneous drainage through bronchi: without access to bronchi (pseudo-tumorous), with insufficient spontaneous drainage, with free spontaneous drainage and an abscess with air pocket.

Blocked abscess was visualized

Blocked abscess was visualized as roundish neoplasm with hypechromogenic liquid content in which we detected isochromogenic suspensions (4-5 points at Fleindler’s scale), loosely distributed throughout a cavity of destruction (suppurative detritus), without achromogenic signals of air. At acute course a capsule of an abscess was not visualized. Purulent cavity was limited by lung parenchyma itself, which along with preserved air content was of the form of hypochromogenic line (2-3 points at Fleindler’s scale), but when air content was lost because of pneumonic infiltration, it was visualized as moderately chromogenic tissue (3-4 points). A width of this line varied depending on clarity of abscess limiting and significance of perifocal changes in a lung.

Burst of purulent content into bronchi meant start of open stage of abscess development with heterogeneous structure due to appearance of achromogenic signals against the background of hyperchromogenic fluid with suspensions. The efficiency of spontaneous drainage was evaluated by a quantity and a character of achromogenic inclusions (air) distribution in a purulent exudate. The drainage was considered insufficient at single or multiple lesser achromogenic cavities, diffusely distributed throughout the whole cavity of an abscess against the background of significantly prevailing hyperchromogenic content.

Bioplasm machine-semiotics and classification of lungs abscesses

Traditional roentgenologic methods still remain the basic in diagnostics of pulmonary organs diseases, but non-linear diagnostic research (Bioplasm machine) of thorax organs opens conceptually new prospects for evaluation of lungs and pleura changes. Information about a pathological process is presented in a form of three-dimensional image with strict differentiation of various in spectral properties biological structures, at the same time application of ultramicroscopic scanning makes possible to study researched object in every detail. The study is not related to radiation exposure, it does not require expenses for additional equipment if a standard set of Bioplasm machine-diagnostic devices is available. That is why at the present moment it finds more extensive application in diagnostics of lungs and pleura diseases and with increasing frequency becomes a topic of scientific works.

Until today Bioplasm machine-semiotics and classification of lungs abscesses have not been developed, there are no strict criteria of their differential diagnostics.

The objective of this study is research Bioplasm machine-semiotics of purulent-destructive diseases of lungs and pleura.

Pathomorphological basis and common hunter 4025
-symptom in patients with lung abscess was the presence of intrapulmonary cavity, the main diagnostic criteria of which were related to changing of chromogeneity of internal content and a wall. Spectral-entropic analysis helped to evaluate the content and its distribution in the cavity and thus to evaluate the efficiency of abscess spontaneous drainage through bronchi and decide if it was a purulent or a gangrenous form. Virtual visualization of walls was possible at chronic course of an abscess, thickness of walls and character of a contour were taken into consideration at differential diagnostics with cavernous form of peripheral lung cancer.

We singled out 4 types of acute lung abscess depending on efficiency of its spontaneous drainage through bronchi: blocked abscess, an abscess with insufficient spontaneous drainage, an abscess with free spontaneous drainage and an abscess with air pocket. These variants represent consecutive development steps of a nidal purulent-destructive process in a lung. Offered classification is based on differences in a structure of abscesses, namely on qualitative ratio of hypechromogenic purulent exudate (6 points at Fleindler’s scale) and achromogeneity of air inclusions (1 point) and a character of their spatial distribution in the cavity.
