- CHYLOUS ASCITES-. presence of milky lymph chyle in the peritoneal cavity with or without infection.
- PERITONEOVENOUS SHUNT-. an operation for the continuous emptying of ascitic fluid into the venous system. fluid removal is based on intraperitoneal and intrathoracic superior vena cava pressure differentials and is performed via a pressure sensitive one way valve connected to a tube traversing the subcutaneous tissue of the chest wall to the neck where it enters the internal jugular vein and terminates in the superior vena cava. it is used in the treatment of intractable ascites.
- PSEUDOMYXOMA PERITONEI-. a condition characterized by poorly circumscribed gelatinous masses filled with malignant mucin secreting cells. forty five percent of pseudomyxomas arise from the ovary usually in a mucinous cystadenocarcinoma cystadenocarcinoma mucinous which has prognostic significance. pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. segen dictionary of modern medicine 1992
- MUCIN 4-. a transmembrane mucin that is found in a broad variety of epithelial tissue. mucin 4 may play a role in regulating cellular adhesion and in cell surface signaling from the erbb 2 receptor protein tyrosine kinase. mucin 4 is a heterodimer of alpha and beta chains. the alpha and beta chains result from the proteolytic cleavage of a precursor protein.

Information for Patients
Also called: Hepatic disease
Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons.
There are many kinds of liver diseases:
- Diseases caused by viruses, such as hepatitis A, hepatitis B, and hepatitis C
- Diseases caused by drugs, poisons, or too much alcohol. Examples include fatty liver disease and cirrhosis.
- Liver cancer
- Inherited diseases, such as hemochromatosis and Wilson disease
Symptoms of liver disease can vary, but they often include swelling of the abdomen and legs, bruising easily, changes in the color of your stool and urine, and jaundice, or yellowing of the skin and eyes. Sometimes there are no symptoms. Tests such as imaging tests and liver function tests can check for liver damage and help to diagnose liver diseases.
