Few infants have been reported who survived fungal endocarditis; all have required both surgical and intensive antifungal therapy. We describe three infants, two weighing less than 1000 gm, who survived Candida endocarditis without surgery. Two had Candida parapsilosis, an agent not previously reported as a cause of neonatal endocarditis. All three infants were treated with amphotericin B and 5-flucytosine. Despite administration of 44, 38, and 48 mg/kg amphotericin B, respectively, no nephrotoxicity was noted; 5-flucytosine therapy was stopped in one infant because of thrombocytopenia. One infant died of an unrelated cause 6 months later; there was no evidence of Candida or endocarditis at autopsy. The other two infants are thriving 2 and 3 years after the completion of antifungal therapy; no remaining evidence of endocarditis is present on echocardiography. We conclude that antifungal therapy without surgery is an option for Candida endocarditis in critically ill infants.

With the introduction of penicillin after World War II, the incidence of syphilis in the United States decreased. Because of penicillin's great success, clinical trials stopped after an initial period of intensive investigation. Syphilis is a difficult disease to study; the natural history may span decades in an individual, and diagnosis and outcome are usually defined serologically, not clinically or bacteriologically. Although the recommended penicillin regimens changed, clinical trials were not repeated. Furthermore, because the early studies occurred before modern clinical-trial methodology was developed, interpretation of the results is difficult. As a result, while current regimens for syphilis therapy are effective, they may or may not be optimal. With the accumulation of reports of treatment failures and the recent appearance of human immunodeficiency virus, current regimens for the treatment of syphilis are being questioned. As background for a meeting at which treatment guidelines were reviewed, the available literature on syphilis therapy is summarized herein.
