[Clinical picture of secondary pneumonia in our observations].

Hundred sixty four patients with the secondary pneumonia were analysed. The secondary pneumonia amounted to 65.8% of all cases of pneumonia treated within several years. Patients' sex, age, clinical symptoms, X-ray findings, coexisting diseases, sequence of the symptoms and the rate of their disappearance were analysed. It was found that the secondary pneumonia is prevailing in males over 40 years of age and most frequently accompany cardiac failure and chronic unspecific respiratory diseases. It is characterized by slow onset and the lack of typical symptoms in the high percentage of patients. Radiological and clinical symptoms disappear more slowly. However, various ausculatory symptoms of pulmonary involvement often accompany the secondary pneumonia and are not directly related to the inflammatory lesion to the lungs.
