A yellow discoloration of the skin, mucous membranes, and sclerae of the eyes caused by greater than normal amounts of bilirubin in the blood. Because persons with dark skin sometiems have yellow-tinged sclerae, the hard palate of the mouth is often the best place to assess for jaundice. Persons with jaundice may experience nausea, vomiting, and abdomical pain and may pass dark urine and clay -colored stools. Jaundice is a symptom of many disorders, including liver diseases, bilary obstuction, and the hemolytic anemias. Physiologic jaundice commonly develps in newborns and disappears after a few days. Rarer disorders causing jaundice are Crigler-Najjar syndrome and Gilbert's syndrome. Useful Diagnostic procedures include a clinical evaluation of the signs and symptoms, tests of liver function, and techniques for direct or indirect visualization, such as x-ray film, computed tomographic scan, ultrasound, enoscopy or exploratory surgery, and biopsy. Also called icterus.
