[Differential diagnostics of febrile conditions in an emergency care clinic].

We undertook the analysis of 157 cases of fever at the stages of polyclinic - admission department - hospital treatment for the purpose of elucidating the structure of febrile syndrome. Pneumonia developed in 45 patients, infectious endocarditis in 34, chronic alcoholic hepatitis in 21, rheumatoid arthritis (pseudoseptic variant) in 2, systemic lupus erythematosus in 1, polymyositis in 2, acute pyelonephritis (exacerbation of chronic pyelonephritis) in 15, tumours of different localization in 37 patients. We evaluated the informative value of some acute-phase blood characteristics obtained, results of X-ray and ultrasonic studies for early diagnostics of pneumonia and infectious endocarditis.
