Effects of inequity on job satisfaction and self-evaluation in a national sample of African-American workers.

Data from a national survey of African-American workers were used to test predictions from equity theory regarding the "distress" that results from negative inequity (below expected level) and positive inequity (above expected level) in pay and occupational prestige. The results showed differential effects of the two types of inequity on dependent variables of job satisfaction and self-report of job-related skill. Although those faced with opposite forms of inequity fostered different strategies for inequity reduction, in each case, workers chose a strategy that was self-protective.

Papillary fibroelastoma of the heart. Report of six cases.

Papillary fibroelastoma is a rare cardiac lesion, mostly encountered as an incidental finding at the time of autopsy but occasionally seen during life. Although this condition generally is asymptomatic, a few cases had been associated with clinical problems, such as embolic phenomena, angina pectoris, outflow tract obstruction, and sudden death. We studied six examples of this lesion, five occurring on the cardiac valves and one on the left ventricular septum. In one, the lesion was detected by echocardiography, which represents to our knowledge only the third published case in which the lesion was visualized by this diagnostic procedure and only the fourth in which the lesion was seen during life. We believe that echocardiography is sensitive in the detection of this often small, intracardiac lesion, useful in evaluating whether a case, by virtue of its size or location, carries a significant risk of causing clinical problems and therefore requires treatment.

Two-dimensional echocardiography in the diagnosis of left atrial myxoma.

We performed M-mode echocardiograms on 11 patients who later had left atrial myxomas removed at operations. Seven of these 11 patients were also examined with two-dimensional echocardiography. M-mode echocardiography showed the characteristic pattern of a left atrial mass entering the mitral orifice during diastole in nine of the 11 patients. M-mode echocardiographic findings were equivocal in two patients because a short tumour stalk prevented significant motion of the tumour. Cross-sectional echocardiography clearly showed a left atrial mass attached by a stalk to the interatrial septum in all seven patients examined, including one patient in whom the tumour was immobile. Three-dimensional measurements of tumour size made from orthogonal cross-sectional echocardiographic planes were within 6 mm of similar measurements made on the excised tumours.
