Crohn’s and ulcerative colitis
in IBD ______ released cause damage
enzymes
In PID (pelvic inflammatory disease) _______ cause damage
microbes
peritoneal cavity should be _______
sterile
infection of the peritoneal cavity results in:
peritonitis
peritonitis may progress to:
abscess
infection of the peritoneal cavity is ________

difficult to treat

microbes can become systemic
life-threatening
inflammation of the peritoneal lining
Peritonitis
Infective peritonitis grouped into three major categories:
#1: primary (spontaneous) bacterial peritonitis (PBP)
#2: peritonitis secondary to intra-abdominal disease
#3: tertiary - peritonitis in patients undergoing peritoneal dialysis (CAPD)
In primary (spontaneous) bacterial peritonitis (PBP)
______ is common
ascites
primary (spontaneous) bacterial peritonitis (PBP)
is often associated with __________
liver disease (cirrhosis)
PBP usually involves ONLY ONE SPECIES. _______
is the common cause (~50% of cases)
E. coli
Pathology of PBP involves
poor liver filtration fx whic
allows for spread of microbes:

1)______are lower in ascites
2) _____ of ascites allow growth of microbes
3)_____ don’t work as well in patients with advanced liver disease
1)Complement proteins
2)proteins
3)neutrophils
pt w/ chronic liver dz presents w/ fever. On PE you palpate an acites which shows >300 PMNs/ml. Blood cx is +.

what is the dx
PBP
after treatmentof PBP, you often see ______ within one year (70% of patients)
recurrence
generalized peritonitis (Peritonitis secondary to intra-abdominal disease) may occur as a result of:
appendicitis

trauma to the GI tract
rupture of intra-abdominal or liver abscess
Peritonitis secondary to intra-abdominal disease is often _______
polymicrobic
Secondary peritonitis is different than PBP in 2 main ways. What are they.
1)polymicrobic
2)often easier to treat than PBP (once correct damage, re-infection unlikely)
Tertiary Peritonitis is peritonitis in patients undergoing _______ (CAPD)
peritoneal dialysis
CAPD Peritonitis is often _______
