Osmotic nephrosis condition, or it may confused with other nephrotic conditions such as Tubular calcineurin-inhibitor toxicity. Affected cells of the proximal tubule may be passed in the urine, but a kidney biopsy is the only sure way to make a diagnosis. Responsible exogenous solutes include sucrose-containing IVIg, mannitol, dextran, contrast dye, and hydroxyethyl starch. Prevention includes standard preventions for iatrogenic kidney damage. Osmotic nephrosis is usually reversible but can lead to chronic renal failure. Osmotic nephrosis Osmotic nephrosis refers to structural changes that occur at the cellular level in the human kidney. Cells, primarily of the straight proximal tubule, swell due to
Pellucid marginal degeneration a distortion in vision. Deterioration can become severe over time. Pellucid marginal degeneration Pellucid marginal degeneration (PMD), is a degenerative corneal condition, often confused with keratoconus. It is typically characterized by a clear, bilateral thinning (ectasia) in the inferior and peripheral region of the cornea, although some cases affect only one eye. The cause of the disease remains unclear. The term "pellucid marginal degeneration" was first coined in 1957 by the ophthalmologist Schalaeppi. The word "pellucid" means clear, indicating that the corneas retain clarity in pellucid marginal degeneration. Pain is not typically present in pellucid marginal degeneration, and aside from
