MMPI profiles of rheumatic fever adolescents and adults.

MMPI elevations for adolescent and adult groups (N = 162) who had experienced rheumatic fever (RF) were generally lower than Mayo Clinic norms, particularly on scales K, 1, 2, 3, and 6. Significant age effects on Scales F, 3, 4, 8, and 9 confirm previous findings that adolescent groups score higher on the MMPI. Contrary to expectation, patients who had not experienced carditis as part of their RF scored significantly higher than carditis patients on scales 2, 3, and 4. The results are discussed from a chronic disease perspective.

Two studies of compliance with daily prophylaxis in rheumatic fever patients in Iowa.

We determined the penicillin compliance rates in school year 1974-75 for 235 children with rheumatic fever through analysis of urine specimens collected at school. Patients relatively low on compliance during the first year of sampling were divided into two equal size groups for a second year sampling study. One-half (N = 44) of these second year study patients and their parents were readvised regarding the need for penicillin prophylaxis and one-half (N = 44) served as controls. We related eductional data, behavioral ratings, and family information to compliance rates in both study years. The overall compliance for the children during the initial sampling year was 64.6 per cent. Factors found to be significantly related to compliance in year one were: 1) male sex, 2) large sibship, 3) increased number of behavior problems, 4) relatively poor academic progress, 5) lower maternal educational level, and 6) recurrence of rheumatic fever. Compliance rates for reinforced patients did not differ significantly from controls during the second year sampling.

Exercise-induced electrocardiographic changes in children with congenital aortic stenosis.

The relationship of exercise-induced electrocardiographic changes to severity of obstruction in congenital aortic stenosis was studied in 44 children. Twelve subjects, with ST segment depression of 1 mm or more lasting 0.08 seconds after the J Point, had left ventricular-aortic peak systolic pressure differences (gradients) ranging from 54 to 112 mm Hg. The remaining 32 children had less than 1 mm or no ST segment depression. Thirty-one of these had gradients ranging from 10 to 48 mm Hg and one had a gradient of 52 mm Hg. Vectorcardiograms, electrocardiograms, and chest roentgenograms were not useful in the identification of the severity of the lesion. The study suggests that children with severe gradients develop electrocardiographic ST segment changes with exercise, thereby helping to select those patients who should have catheterization studies to delineate the severity of the lesion. In those with a normal exercise test, cardiac catheterization may be safely delayed, but the exercise test should be repeated to identify those who develop progressive obstruction.
