[DIFFICULTIES OF DIFFERENTIAL DIAGNOSTICS OF SEVERE COMMUNITY-ACQUIRED PNEUMONIA].

Severe community-acquired pneumonia implies the necessity of its early differential diagnostics from a wide range of nosological forms requiring not only therapeutic but also surgical treatment. The authors consider the causes of hypodiagnostics of community-acquired pneumonia and illustrate difficulties of differential diagnosis of this condition by concrete examples.

[Pulmonary cytotoxicity induced by bleomycin and methotrexate].

Early detection of drug-induced pulmonary parenchymal injuries is often hampered by nonspecific clinical and X-ray manifestations. The diagnosis is usually based on a history of drug use, clinical and X-ray presentation, and exclusion of other causes of lung tissue injury. Chemical preparations most commonly cause pathological pulmonary changes.
