Renal biopsy. Left kidney ultrasound guided biopsy performed on day 27. Photomicrographs to show histopathological findings; a acute tubular necrosis with dilation, epithelial thinning, tubular cell necrosis and regeneration, interstitial oedema, and minimal inflammation (haematoxylin and eosin stain ×200); b acute tubular injury with PAS staining showing loss of brush border in the dilated injured proximal tubules (Periodic acid Schiff ×200); c a normal glomerulus (×400 Jones methanamine silver stain), and d a Perls stain for iron showing particulate and diffuse staining in damaged proximal tubules (×400). Specialized PAS, methanamine, and Perls straining were performed in Bangkok, Thailand since only haematoxylin and eosin stain was available in Bangladesh.
