Write answer in between .Q:A 5-year-old boy is brought to the office by his mother with complaints of facial puffiness and frothy urine for 4 days. The puffiness first started in his eyes and then spread to the face. His mother does not provide any history of similar symptoms in the past. Past medical history is non-significant. His birth history is uneventful and all his vaccinations are up to date. The vital signs include: blood pressure 10062 mm Hg, pulse 110min, temperature 36.7C 98.0F, and respiratory rate 16min. On examination, there is pitting edema of the upper and lower extremities bilaterally.Urinalysis results are as follows:pH 6.2Color light yellowRBC noneWBC 34HPFProtein 4Cast Fat globulesGlucose absentCrystal noneKetone absentNitrite absent24-hour urine protein excretion 4.1 gA renal biopsy is sent which shows normal glomeruli on light microscopy. Which of the following is the most likely diagnosis?? A: Membranoproliferative glomerulonephritis, B: Post-infectious glomerulonephritis, C: Focal segmental glomerulosclerosis, D: Lipoid nephrosis, E: Membranous nephropathy,  <response>: Based on the information provided in the question stem, this seems to be a case of nephrotic syndrome in a young child. The key findings are facial puffiness, frothy urine, pitting edema, heavy proteinuria on urinalysis, and normal glomeruli on renal biopsy. The differential diagnosis for nephrotic syndrome in children includes minimal change disease, focal segmental glomerulosclerosis FSGS, membranoproliferative glomerulonephritis MPGN, and congenital nephrotic syndrome. However, the normal glomeruli on biopsy make minimal change disease lipoid nephrosis the most likely diagnosis.Membranoproliferative glomerulonephritis choice A typically shows glomerular abnormalities on biopsy. Post-infectious glomerulonephritis choice B presents with hematuria and hypertension, not massive proteinuria. Focal segmental glomerulosclerosis choice C and membranous nephropathy choice E would also have abnormal findings on renal biopsy.D: Lipoid nephrosis
