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.
Lilac Flowers. There is nothing better than a large bouquet of lilacs on the kitchen table in early spring. The pleasant, sweet scent of a freshly picked bouquet, is almost too strong to leave in the room, without a window open. Select Lilac flowers that have almost all flowerets open. Cut the stem several inches below the flower.
