Catheter Break-in for Continuous Ambulatory Peritoneal Dialysisuniversity of Missouri Experience

Retrospective analysis of the results of several break-in techniques in our institution revealed that a 10 day delay in CAPD initiation after a midline Tenckhoff catheter insertion is sufficient to prevent leakage in patients maintained on intermittent peritoneal dialysis. A leak or obstruction related to an insufficient surgical technique can be promptly diagnosed and corrected. An irrigation technique seems to be useful in non-uremic patients, but frequently fails to disclose a one-way obstruction with a consequent delay in a surgical correction. Recently we have introduced a modification of this technique in which the patency of the catheter is checked with one in and out exchange using a small volume of dialysate during outpatient clinic visits every 2– 3 days.

[The dynamics of parodontal disease incidence in young subjects in Cracow in 1969-1988]

The reported study was carried out on 1241 subjects aged from 5 to 25 years with symptoms of parodontal diseases who came to an outpatient clinic in the years 1969-1988. Gingivitis prevailed among the diagnoses--825 cases, while deep parodontal changes were found in 416 cases. The incidence of all parodontal diseases was higher in females, with the exception of ulcerative gingivitis which was more frequent in males. The patients from the City of Cracow prevailed over those from the provinces of Southern Poland, and the incidence of various disease entities varied in various years.
