Acute pneumonia - the Differential diagnosis of pneumonia
Page 1 of 11
The inflammation of a parenchyma and interstitial tissue of lungs is called pneumonia. Clinically it is shown by fever and consolidation of pulmonary fabric. Pneumonia, as well as many other clinical units, can be primary disease or only one of syndromes of any general disease, for example a typhoid, flu. Depending on a way of infection pneumonia at some diseases, for example tuberculosis, can be the first or one of late displays of a disease. Pneumonia at which lungs are the main place of an illness understand the present section. Practically such pneumonia can be caused by any microbe entered into tracheobronchial system.
Modern methods of therapy of pneumonia are highly effective only in cases when specificity of the activator is defined. Opportunities and restrictions of clinical methods of research in diagnosis of pneumonia have to be known to each doctor as therapy of its bacterial forms has to begin at once after establishment of the preliminary diagnosis, to X-ray inspection and receiving results of special laboratory blood analyses, urine and a phlegm. The attention to features of clinical manifestations of separate types of pneumonia and their continuous comparison to results of X-ray inspection of the patient is also explained by it.
It is well-known that clinical signs of pneumonia appear sometimes on 24 h before radiological and that the central pneumonia sometimes can be revealed only by a radiological method of research. The final conclusion according to X-ray inspection is defined approximately equally by both character of teneobrazovaniye of lungs, and nature of clinical displays of diseases. Also true diagnostic value of results of a blood analysis and phlegm is defined by set of clinical data.
According to the division of pneumonia accepted in domestic literature by the etiological and morphological principles carry out the differential diagnosis of separate pneumonia in the beginning, and pay special attention to the clinical and laboratory signs allowing to put the presumable, and then and final etiological diagnosis. For difference of pneumonia from an infiltration of lungs of other origin especially the importance acquires knowledge of morphological features of the compared diseases and acquaintance to patterns of their clinical current.
As this work is counted on the practical doctor, either similarity of their clinical manifestations, or features of their emergence are the basis for group of pneumonia. The first presumable diagnosis of pneumonia is made on the basis of the anamnesis (quite often professional) and data of physical research of the patient. Further diagnostic work is directed to verification of the preliminary diagnosis and if it is confirmed — on clarification of an etiology of pneumonia.
The majority of pneumonia has an infectious origin. Pneumonia the allergic and caused by action of physical or chemical factors environments meets much less often.
