Pneumonia

The inflammations of the lung or pneumonias (commonly pneumonias), they are usually produced by bacteria but viral pneumonias, rickettsiósicas, etc also exist. the germs pathogens arrive to the lung transported by the blood stream, or for top-down propagation of infectious processes of the respiratory higher channels: rinitis and pharyngitis that, if they descend, they can give place to laryngitis, to traqueítis, to bronchitis and even to infections of the own lung.

Conjointly with the pneumonias we should mention the bronchopneumonias. In the pneumonias a pulmonary single inflammatory focus exists, of enough extension: it embraces to great part of a lobe, to one complete, or to more than one. In the bronchopneumonias the pulmonary inflammation is plurofocal: the aflame fields of the lung are usually pettier than in the pneumonia, but they exist different. The same germs that cause the pneumonias can give origin to bronchopneumonias.

The pneumonias and bronchopneumonias are always important illnesses. They study with deep prostration, fever, side (if the focus inflammatory wound until the pleura) pain, cough with scarce expectoration and breathing difficulty.

The most frequent bacterial pneumonia is the neumocócida. 90% of the bacterial pneumonias is neumocócidas and they are very sensitive to the antibiotics, especially to the penicillin.

Commonly it is believed, and until many physicians they admit it that from the input of the antibiotics in the treatment of the infections, the frequency of the pneumonias has diminished a lot of .Pero the reality it is that the pneumonias continue being as frequent as before the antibiotic and chemotherapeutic therapy; what has diminished has been its graveness and mortality: the systematic practice, in hospital centers, of thorax x-rays in patient acute affections of respiratory infections confirms it. But given the effectiveness of the antibiotics in the pneumococcal pneumonia, and to be this the most frequent bacterial pneumonia, many of these illnesses, are cured without book credit diagnostigadas.
