Despite its continuing allegiance to the designation of "Conference on the Nephrotic Syndrome," this report demonstrates the conferees' tendency to broaden the base of renal disease to which the conference devotes itself. The widespread concern regarding subclinical urinary tract infection is responsible for a section on Infection and Renal Disease, although both immunogenic renal disease and urinary infection are discussed in this section. The material presented is, for the most part, pertinent, but it is difficult to see that a discussion of viruses in monkey kidney cells, probably nonpathogenic for renal tissue, is germane to the problem of renal disease. The pyelonephritis data are largely derived from adult studies.
The role of countercurrent mechanisms in urinary concentration and investigations of renal reabsorption of sodium are discussed by the renal physiologists whose contributions are significant and well known. The papers presented by Drs. Ullrich, Schmidt-Nielsen, Gottschalk, Wilde, and LeBrie elucidate the
