[Recurring peritonitis due to Streptococcus from the upper respiratory tract in a saxophone player under peritoneal dialysis].

This is a nephrectomized patient of 77 years, musician (saxophonist), in peritoneal dialysis, with diabetes, hypertension, and coronary disease. He presented a few months apart two successive episodes of peritonitis due to Streptococcus mitis/oralis and Streptococcus parasanguis. Before each episode he played the saxophone he played twice and each time he has peritonitis. Colonoscopy objectifying a sigmoid polyp. The assumption of self-contamination of the patient was supported by the fact that S. mitis/oralis and S. parasanguis are oral streptococci, and the intraperitoneal pressure (IPP) from 8 to 32 cm of water when the patient plays the saxophone. In this measurement of IPP we have also seen how the saliva is spread on all sides when playing the saxophone. Our patient is now cured and did not include the saxophone.
