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.
Studies show that smokers lose some of their ability to smell. That can make life a lot less pleasurable. If you lose your sense of smell, you can't appreciate the scent of spring flowers or an ocean breeze. Eating becomes a lot less rewarding too, since aroma contributes a great deal to the flavor of food. Life could even become more dangerous, since you may be less able to detect the odor of a gas leak or a house fire.
