title: Acute kidney injury following ingestion of plate developer (sodium metasilicate): a case report.
abstract: BACKGROUND
  Plate developer is a chemical used in the printing industry and is a corrosive alkaline agent containing sodium metasilicate as the main substance. Plate developer poisoning is rare. Literature search revealed only a single case report of fatal sodium metasilicate poisoning (Z Rechtsmed 94(3):245-250, 1985). There are no reports of acute kidney injury related to ingestion of sodium metasilicate containing substances.
  
  
  METHODS
  A 52-year-old Sri Lankan male with a history of hypertension and affective disorder presented following ingestion of about 150 ml of plate developer solution. He developed severe upper airway obstruction due to laryngeal edema and underwent tracheostomy. While in the ward he developed features of acute kidney injury with high serum creatinine levels and persistent hyperkalemia which necessitated temporary haemodialysis. Because of the corrosive effect, he developed severe inflammation of the upper gastro intestinal tract with narrowing of esophagus and pyloric region, requiring feeding jejunostomy. He died while waiting for the surgery for pyloric stenosis.
  
  
  CONCLUSIONS
  Acute kidney injury is a potential treatable complication of plate developer poisoning other than its complications related to corrosive effects. Regular monitoring of renal functions in such a patient would be useful for early recognition of acute kidney injury.
