Reversible Nephrotic Syndrome Resulting from Constrictive Pericarditis

Abstract
THE clinical concept of the nephrotic syndrome, a state characterized by edema, proteinuria and hypoproteinemia, has been extended from its classic application to a few renal diseases classified as "nephroses"1 to a variety of unrelated conditions that may lead to massive albuminuria. In a recent review Kark and his associates2 enumerated thirty-six causes of the nephrotic syndrome and classified them into seven general groups: heredofamilial; infective; toxic; allergic; mechanical; those due to generalized pathologic processes; and those due to intrinsic renal disease.One of the less well recognized causes of the nephrotic syndrome is the mechanical effect of increased pressure . . .
