Clinical features of patients suffering from Streptococcus milleri infections--a retrospective analysis.
We examined the clinical records of patients from whom S. milleri was isolated at Kyushu University Hospital from January 1987 through December 1988. Sixty-one patients were treated in 64 episodes with drainage or antibiotics. Oral and nasopharyngeal infections were observed in 27 cases, intrathoracic infections in 13, urogenital infections in 8, intraabdominal infections in 6 and skin and subcutaneous infections in 6. Except for acute bronchitis and urogenital infections, all of them were suppurative. As to underlying diseases, 21 patients had malignancies and 6 had diabetes mellitus. Leukocytopenia was not observed in any of the patients. S. milleri can be eradicated by treatment but it is sometimes replaced by other organisms. However, considering its tendency to cause suppurative infections, its pathogenic significance should be taken into account and patients should undergo surgical drainage combined with antibiotic therapy.
