Selective proteinuria is typically seen in: 
Select and explain. 
A. Nil lesion, B. Diabetic nephropathy, C. FSGS, D. Mesangioproliferative glomerulonephritis
A: Nil lesion
Answer: A: Nil lesion 
Explanation: Sustained proteinuria >1-2 g/24 h is associated with glomerular disease. functional or transient proteinuria causes <1-2 g/24h urine protein loss. Proteinuria seen with upright posture is called ohostatic proteinuria. Isolated proteinuria is seen in diabetic nephropathy, nil lesion, mesangioproliferative glomerulonephritis, and FSGS. Proteinuria in these conditions is mostly nonselective, containing albumin and a mixture of other serum proteins. In children with nil lesion from minimal change disease, the proteinuria is selective and largely of albumin Ref: Harrison-18, P-2336.
