Use of Dacron cuffed silicone catheters as long-term hemodialysis access.
Sixty-five Dacron cuffed, dual lumen, silicone central venous dialysis catheters (Quinton PermCath, Seattle, WA) were inserted in 51 patients as the sole form of permanent access for chronic hemodialysis. Six and 12 month actuarial survival rates of patients for all catheters were 53% and 35%, respectively. When calculations included revisions, 6 and 12 month actuarial catheter survival rates were 61% and 43%, respectively. The major limiting factors in survival using long-term catheters remain infection and thrombosis. Dacron cuffed, dual lumen, central venous, dialysis catheters can provide long-term vascular access for hemodialysis in high risk patients.

Cardiac profile and disruptive behavior in boys at risk for delinquency.
The objective of this study was to examine associations in youth between antisocial behavior and cardiovascular profile. Younger brothers of adjudicated delinquents (N = 120) received a standardized psychiatric assessment and an assessment of three factors often studied in behavioral cardiology research: family history of hypertension, resting blood pressure, and obesity. As a group, relative to population norms, these youth exhibited signs of obesity and elevated blood pressure, with 30% of the sample appearing clinically obese and 24% having a blood pressure above the 90th percentile for national norms in their age cohort. Within the sample, score on the Child Behavior Checklist (CBCL) Delinquency scale correlated with blood pressure (r = .29-.34) and an index of obesity, weight/height3 (r = .20). Further, scores on the CBCL Delinquency, Aggression, and Externalizing scales were elevated in boys with a positive family history of hypertension. Among boys at risk for delinquency, disruptive psychopathology relates to factors often studied in behavioral cardiology research. Relationships between risk factors for ischemic cardiovascular disease and hostile behavior may be manifested with measures of disruptive psychopathology.
