Evaluation of patients undergoing senning repair with two-dimensional contrast echocardiography.
The postoperative anatomy of the Senning interatrial diversion was defined by two-dimensional contrast echocardiography in ten patients. A modified apical four-chamber view proved most valuable, allowing for simultaneous visualization of both the systemic venous atrium and the pulmonary venous atrium. The anatomy was confirmed with two-dimensional contrast echocardiography utilizing catheters placed in the systemic venous atrium and pulmonary venous atrium at the time of surgery. In addition, in several of the patients, we were able to detect atrial or ventricular level shunts which were not clinically apparent. One patient who was judged to have a significant shunt by two-dimensional contrast echocardiography had no anatomic site found at autopsy to explain the shunting. We conclude that two-dimensional contrast echocardiography can define the postoperative anatomy following Senning repair allowing for immediate and future evaluation. Shunting at the atrial and ventricular levels can also be detected, but the method is very sensitive and difficult to quantitate or correlate clinically.

Differences between learning disability subtypes classified using the revised Woodcock-Johnson Psycho-Educational Battery.
This study examined the characteristics of students with specific learning disabilities in either reading and spelling or arithmetic. Based on scores obtained using the revised Woodcock-Johnson Psycho-Educational Battery, students with a marked weakness in arithmetic relative to reading and spelling were designated as Group A. Group R-S showed the opposite pattern. Each group included 30 participants ranging in age from 7 to 16 years, with a mean age of 10 years. The boy-to-girl ratios were 16:14 and 19:11 in Group A and Group R-S, respectively. Comparisons using measures from the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) indicated that Group A was weaker in nonverbal skills than Group R-S, despite equivalent overall IQ scores between the two groups. Group R-S showed a within-group strength in nonverbal versus verbal skills. Group A students were more likely than Group R-S students to have counseling provided as part of their Individualized Education Program, suggesting greater socioemotional difficulty among Group A students. The present study supports the connection between nonverbal skills and socioemotional functioning noted by previous researchers, and generalizes findings from earlier studies to more current test editions.

ABO blood group and serum lipids in female atherosclerosis.
Seventy-three women requiring aortoiliac reconstruction for atherosclerotic occlusive disease were reviewed to determine the frequency of blood groups, lipid status and associated cardiovascular risk factors. These women demonstrated an increased frequency of blood group A (48% versus 36% control, p less than .01), which is comparable to published data for their male counterparts. Hypertriglyceridemia, not hypercholesterolemia, was found in this female population, but was not significantly correlated with any specific ABO blood group. Rhesus factor was not significantly different from the control population. There was a trend toward occlusive, rather than stenotic, atherosclerosis among women with blood group A. Statistical analysis revealed that blood group A was not just a marker for other standard cardiovascular risk factors, but rather represented an independent risk for peripheral occlusive disease.
