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
Transneuronal degeneration in the fornix, mammillary bodies, and contralateral cerebellum. It has recently been shown that transneuronal degeneration can also be caused after respiratory chain-deficient neurons develop from "de novo" mitochondrial DNA mutations, which are normally associated with mammalian ageing. The respiratory chain-deficient neurons have adverse effect on normal adjacent neurons, inducing death by means of transneuronal degeneration. Transneuronal degeneration in these cases is accelerated during the ageing process since other cellular maintenance systems are already damaged as well as in the presence of mitochondrial disease, where non-neuronal cells like glial cells and astrocytes also have respiratory chain deficiency. This also means
