Review of the treatment literature for encopresis, functional constipation, and stool-toileting refusal.

This review summarizes the literature on randomized, controlled, published studies involving medical, behavioral, psychological, and biofeedback treatments for encopresis/functional constipation and stool-toileting refusal in preschool-age and school-age children. Nine such studies were located in the literature involving school-age children. No randomized, controlled treatment studies involving preschool-age children have been published.

Cardiovascular responsivity to stress in adolescents with and without persistently elevated blood pressure.

Objectives: The goal of this study was to compare the cardiovascular responses to behavioural stressors of three groups of adolescents who differed in blood pressure status across assessments.

Design: Casual blood pressure of adolescents who were identified as having elevated blood pressure during a school screen was re-evaluated in the laboratory. The adolescents were classified into two groups: (i) those with consistently elevated blood pressure across school and laboratory assessments and (i) those with labile blood pressure whose blood pressure in the laboratory was below 130/80 mmHg.
