Liver Biliary Pancreas Flashcards
Describe prehepatic
1-Caused by excessive hemolysis
The hemolysis being due to diseases that cause an abnormal RBCs
1-due to sickle cell anemia, or
2-hemolytic disease of the newborn
hemolysis mechanical factors
1-rbc’s breaking from hitting artificial heart valves
2-enlarged spleen
Jaundice
Cause and classifications (3)
Yellowed skin or sclera
Bilirubin build up to amount of hyperbilirubinemia
Classifications: prehepatic (before liver processes the bilirubin)
Hepatic (problem in the liver)
Post hepatic (problem occurs after the processing in the liver)
Hepatic disorders/diseases
define hepatic and name three hepatic disorders.
Bilirubin process gone wrong within the liver;not metabolized - not released into the bile.
Hepatitis
tumors
Cirrhosis
Posthepatic
Define and name four types of disorders
Posthepatic occurs after the file gets excreted from the liver. Blockages from gallstones and tumors can obstruct the flow of bile; the bile cannot leave the liver normally. 1-Gallstones 2-tumors of the biliary ducts 3-tumors of the ampulla of Vater 4-tumors of the pancreas
Define Hepatitis
name two types of hepatitis
Hepatitis is inflammation of liver tissue not referring to a bacterial problem
two types -viral forms, one is toxic such as alcohol
Viral hepatitis name the four different forms
Hepatitis A -hepatitis B - hepatitis C - hepatitis D - hepatitis E - etc. variable symptoms and the closer they are to the beginning of the alphabet the more common they are
Most common or A, B, C
What type of virus is hepatitis A ? how is it spread? what is the incubation? How prevalent? what are the symptoms and major complications?
hepatitis A. is an RNA virus. Spread via feces or oral. Short incubation 15 to 50 days. most prevalent children in undeveloped nations. symptoms mild fever vomiting jaundice. Major and rare complications cirrhosis. Disease can be tracked.
hepatitis B
what kind of virus is it? how is it spread? What is incubation period? What are the symptoms?
Hepatitis B is a DNA virus.
Spread infected blood body fluids
Incubation 40 to 180 days
symptoms in three phases
first preicteric - weakness, nausea, vomiting, tender liver
Second icteric - variable levels of jaundice (icteric or icteris is jaundice)
Third convalescent - not all patients recover. Can become chronic hepatitis or liver cancer. Cancer can be fatal
Hepatitis C.
what kind of a virus? How is it spread?
Who most commonly gets it? what is the incubation? What are the symptoms?
Hepatitis C
is an RNA virus
spread through blood body fluids
most cases drug abusers
incubation similar to hep B
symptoms similar to B but less severe but potential complications.
80% of infected will recover 20% will have chronic hepatitis C and die of liver failure or cancer. Previously spread through transfusions. Long incubation period.
Explain which hepatitis is least problematic and which hepatitis is worse. Which hepatitis has an immunization?
Hepatitis C is worse than hepatitis A and not as bad as hepatitis B. Hep C 80% of infected will recover and 20 will have chronic and then die of liver failure or cancer.
hepatitis B has an immunization. Hepatitis a has an immunization offered if you are going to a foreign country. No immunization for hepatitis C.
Toxic forms of hepatitis.
Alcoholic liver disease
Early symptoms are fatty liver which is called steatosis. Later in the disease is alcoholic hepatitis with similar symptoms without the viral changes.
Hemochromatosis
explain what kind of a disorder this is (meaning genetically)
what does it lead to?
Hereditary autosomal recessive disorder. The defect of iron absorption. Liver stores iron; the defect is in the storing which results in excessive amounts of iron. Iron damages liver cells if prolonged and scarring will develop which will lead to cirrhosis. Liver turns unnatural brown. Excessive accumulation of iron can be in the liver and in other organs.
Wilson’s disease what type of disease is this (genetic)?
Explain what it is and what it leads to.
Hereditary autosomal recessive disorder.
Defect in copper metabolism.
Lesions in the liver, brain and eye. Toxic to these organs.
In the eyes brownish discoloration of the iris called Kaiser Fleischer rings.
Alpha-1 antitrypsin deficiency
what type of disease is this
and what does it lead to?
A hereditary autosomal recessive disorder
Cholestasis which means the buildup of bile
most of these diseases are not diagnosed in children but it can lead to chronic hepatitis in young children.
Biliary system
immune disorders
name two diseases
Primary biliary cirrhosis
primary sclerosing cholangitis
Both diseases destroy biliary system in the cause obstruction. Antibodies attack the bile ducts then there is no way for the bile to get out of the liver.
