The ddx of intrinsic renal disease is: glomerular, tubular, interstitial, or vascular 3. Glomerulonephritis presents with an active sediment (RBC, protein) and nephrotic syndrome presents with a bland sediment (heavy protein, otherwise negative U/A).
Smell is the most subtle of senses touched by spring. In spring there is the sweet fragrance of flowers, which is perhaps the first thing many think of. But my thoughts are drawn to subtler scents. In winter the sun is low and weak, giving little light and even less warmth.
Ooooh, That Smell...Must Be Skunk. February through March is mating season for striped, hog-nosed, and hooded skunks, hence why their signature smell is so common around those times. Used as a defense mechanism, skunks spray each other when competing for a mate or when unreceptive to courting attempts.
