Candidal suppurative peripheral thrombophlebitis.

Transient candidemia is common with prolonged intravenous therapy. Sustained candidemia, however, usually indicates a persistent focus of infection. A complication of intravenous therapy not previously emphasized is persistent candidemia caused by candidal suppurative peripheral thrombophlebitis. We report six cases that appeared during intravenous therapy: the infection was characterized by a thrombosed peripheral vein at an intravenous site with manifestations for candida septicemia with or without disseminated candidiasis. In two patients, the source of the process was occult; the examination showed only a thrombosed noninflamed vein. In all cases, surgical exploration showed the thrombosed veins to be suppurative with positive cultures for Candida. Special stains, moreover, showed Candida in the luminal clot and the vascular wall. In the five surviving patients, cure was achieved by excision of the affected vein. Four received a short course of amphotericin B and 5-fluorocytosine, and one patient received amphotericin B only.

Hemophilus influenzae pneumonia in adults: report of five cases caused by ampicillin-resistant strains.

Recently there has been increased recognition of Hemophilus influenzae as a cause of pneumonia in adults. Although ampicillin-resistant strains of Hemophilus influenzae have been a major problem in pediatric practice, such strains have not previously been noted to be a significant problem in the treatment of adult pneumonia. We report 5 cases of pneumonia caused by beta-lactamase-producing strains of Hemophilus influenzae. These organisms were susceptible to chloramphenicol but resistant to ampicillin. Cure was achieved by treatment with chloramphenicol after the initial treatment with ampicillin had failed. The ability of a microbiology laboratory to isolate and to test routinely for ampicillin-resistant strains is an important factor in the successful treatment of Hemophilus influenzae infections.
