pancreas liver gallbladder Flashcards
After a meal, excess glucose molecules are taken up by the liver, combined, and then stored as glycogen
Glycogenesis (gli-co- genesis)
When blood glucose level falls, the process is reversed, and the glucose molecules are returned to the blood
Glycogenolysis (gli-co-geno-lysis)
Fats and protein broken down in response to low blood glucose levels, and molecules are used to make new glucose
Gluconeogenesis (glu-co-neo-genesis)
Primary palmar erythema
Heredity.
Pregnancy (due to alterations in skin function and vasculature).
Idiopathic.
Secondary palmar erythema
Livercirrhosisand its many causes includingalcohol abuse.[(Palmar erythema develops as a result of abnormal oestradiol levels.)
Hereditary liver disease such asWilson’s diseaseandhereditary haemochromatosis.
Locally, inflammatory process causes the liver to swell
Bile channels compressed; damage the cells that produce bile
Then blood flow through the liver is impaired, causing pressure to
rise in the portal circulation
Systemic effects related to altered metabolic functions performed by
the liver and to the infectious response in viral
Hepatitis
Signs and symptoms
Hepatitis
Signs and symptoms of systemic effects: rash, arthritis, fever,
malaise and angioedema, (the rapid swelling [edema] of
thedermis,subcutaneous tissue,mucosa and submucosal
tissues.)
: caused by exposure to toxic chemicals; drugs
Noninfectious: Hepatitis
Exposure to fecal contaminated water, food or
medical equipment. Most common type of viral
hepatitis
hep A
Blood borne, found in all body fluids of infected….
Transmit by intimate contact with carriers, exposure to
infected blood
hep B
Becomes “C”hronic and a “C” arrier of Hep.
Increases risk of chronic liver infections
Hep C
Caused by delta agent… RNA virus that can only
survive in the presence of Hep B..therefore blood
borne
hep D
Similar to Hep A.. Trasmit via water or food… rare in
US. No long term effects
Hep E
: Identified in some blood donors and transmits by
blood transfusion… does not cause chronic hepatitis..
But effects not fully known
Hep G
Signs and symptoms regardless of cause are similar
Preicteric phase
Hepatitis
Malaise, severe headache, right upper quadrant abdominal pain, anorexia, nausea, vomiting, fever, arthralgia (joint pain), rash, enlarged lymph nodes, urticaria, liver enlargement and tenderness
Icteric phase
Hepatitis
Jaundice, light or clay-colored stools, dark urine
Posticteric phase
Hepatitis
Fatigue, malaise, and liver enlargement
Medical diagnosis
Hepatitis
Elevated levels of serum enzymes (AST, ALT, GGT), serum and urinary bilirubin, and urinary urobilinogen
Medical treatment
Hepatitis
No cure: treat to promote healing and manage symptoms
Antipyretics, corticosteroids, and antiemetics
Diet: high calorie, high carbohydrate, moderate to high protein, and moderate to low fat with supplementary vitamins
Prevention
Hepatitis
Vaccines; immune globulin (IG); hepatitis B immune globulin (HBIG)
