ALBUMINURIA OF EFFORT

THE mechanism of the production of so-called xbenign albuminuria, as opposed to the type associated Iwith renal disease, has given rise to much speculation. nVarious types of benign albuminuria have been

rdescribed as following severe exercise, mental strain, rexposure to cold, or a large intake of protein, or as vpreceding menstruation. Another type known as tessential (cyclic, postural, or orthostatic) albuminuria thas also received attention. Hellebrandt and his 1co-workers hold that the albuminuria of effort is con-

xnected with the fall in pulse-pressure which is always xfound after severe exercise. The postulate that exer- jcise is followed by a peripheral vasodilatation and jconsequent reduction in the renal circulation. This 1produces renal anoxaemia, with increased permeabilityof the capillary membranes of the kidneys. On the ’

other hand Wamisch and Mevler believe it is theacidity of the urine after exercise which causes the 1

albuminuria. Govaerts and Lanne have now made a "

careful study of the problem in students from a

military training school. Their investigation showsthat the amount of albumin appearing in the urineafter muscular effort is in proportion to the intensityof the work done. Albumin and tubular casts appearfor only a very short time after effort and duringthis period there is a fall in pulse-pressure. If enoughalkalis are taken beforehand to keep the urine alka-line after the exercise, the albumin and casts are

reduced and sometimes do not appear at all.

of attitude towards head injuries. What was formerlyregarded as a purely surgical preserve is now beingopened up to the physician and the psychiatrist. No
