In this field the most conspicuous investigative activities during the past year have been concerned with renal factors in hypertension, growing out of Goldblatt's work. Interest has been sustained in the nature of glomerulonephritis, in the renal disorders of pregnancy and in pyelonephritis. Studies of renal function have been concerned with intermediate steps in the formation of urine in health and in disease.
Baehr1 takes issue with those who would make a diagnosis of diffuse glomerulonephritis on the basis of urinary abnormalities alone or on the postmortem observation of diffuse glomerular changes in diseases, such as rheumatic fever, in which manifestations of nephritis are inconspicuous or lacking. Since glomerulonephritis must be considered a general vascular disease, of which the renal lesions are only a part, there should be evidence of extrarenal vascular damage to substantiate a diagnosis. He points out the rarity of gross clinical manifestations of glomerulonephritis
