Infant mortality in SMSAs before Medicaid: test of a causal model.

Path analysis is applied to data on infant mortality, supplies of physicians and hospital beds, and population percentages of blacks and low-income families in 201 standard metropolitan statistical areas (SMSAs) to test the hypothesis that medical resources mediate the effects of racial composition and low income on infant mortality rates. The hypothesis is not supported for the SMSA data: direct effects of racial composition and low income on infant mortality are stronger than indirect effects. The use of SMSA data for analysis is contrasted with the use of county data in a discussion of study by Anderson, from which the hypothesis was drawn.

Missile migration from lung to heart with delayed systemic embolization.

A bullet migrated from the heart to the left femoral artery in a youth ten days after he sustained a gunshot wound to the right chest. The bullet apparently traversed the pulmonary venous system at the time of the injury and lodged in the interior of the left ventricle. The production of an embolism in the systemic circulation was a delayed and unanticipated event.

Surgical treatment of Ebstein's anomaly.

Neither the role of surgery in Ebstein's anaomaly nor the surgical procedure of choice for its correction are clearly defined. Whether or not the artrialized right ventricle, which plays a major role in the functional abnormalities, should be obliterated in all cases remains unresolved. Of the 26 patients with Ebstein's anomaly seen at the University Hospital between 1953 and 1975, four were treated surgically at this center. All had closure of the atrial septal defect, reconstruction of a tricuspid annulus in the normal position, and insertion of a tricuspid prosthesis and an epicardial ventricular pacemaker. The two patients who also had the atrialized chamber obliterated improved dramatically. Thus, obliteration of the atrialized right ventricle appears to be associated with a better operative result.

Experience with the radial artery graft for coronary artery bypass.

Forty-eight radial artery grafts and 22 saphenous vein grafts in 37 patients undergoing coronary bypass procedures were studied early postoperatively. Most of the saphenous vein grafts were patent, but one-half of the radial artery grafts were occluded. Failure of the radial artery grafts could not be attributed to unfavorable runoff in the recipient vessels. Radial arteries carrying higher flows and those to vessels having more severe degrees of proximal stenosis occluded with a higher frequency. The radial artery should not be used for coronary bypass.

Path analysis of socioeconomic correlates of county infant mortality rates.

Relationships between selected socioeconomic characteristics of counties and infant mortality rates are examined. There are two research objectives: to determine the extent to which low family income, low education, sound housing, and the percentage of blacks "directly" and "jointly" relate to neonatal and postneonatal mortality rates; and to determine the degree to which a zero-order correlation between a given socioeconomic measure and general infant mortality is transmitted by neonatal and postneonatal mortality rates, respectively. Data corresponding to 2237 counties in the United States are analyzed by path analysis. Results show that the percentage of blacks and low education are two variables which have appreciable direct effects on both components of infant mortality. These two factors are also responsible in large measure for gross associations between low family income, sound housing, and rates of infant loss. On the basis of this study it is estimated that approximately two-thirds of the zero-order correlation between a given county measure of socioeconomic status and infant mortality occurs through the postneonatal component. Implications of these findings are discussed.
