Q

Example of primary chronic inflammation with an unknown aetiology

A

Ulcerative colitis

17
Q

Example of chronic inflammation caused by primary granulomatous disease

A

Sarcoidosis

18
Q

What is sarcoidosis?

A

The build up inflammatory cells indicating a chronic response

19
Q

What factors favour progression from acute to chronic inflammation?

A

Indigestible substances

Deep seated suppurative inflammation where drainage is delayed or inadequate

20
Q

What causes suppurative inflammation to develop into chronic inflammation?

A

The thick abscess wall

Fibrous/ granulation tissue beginning to form

Pus becoming organised

Formation of fibrous scar

21
Q

What is osteomyelitis?

A

Chronic abscess which is extremely difficult to eradicate

22
Q

What is an example of a disease caused by recurrent episodes of acute inflammation?

A

Chronic cholecystitis

23
Q

What is chronic cholecystitis?

A

Replacement of wall by fibrous tissue

24
Q

What does chronic ulcer look like?

A

Mucosa breached

Base lined by granulation tissue

Fibrous tissue throughout muscle layers

25
Q

What does chronic inflammation look like?

A

Chronic ulcer

Chronic abscess

Thickening of the all of a hollow viscus

Granulomatous inflammation

Fibrosis

26
Q

What immune cells are common in chronic inflammation?

A

Plasma cell

Lymphocyte

Macrophage

Multinucleate giant cell

27
Q

How do macrophages act as the immune cells?

A

Phagocytic

Produce a range of important cytokines

28
Q

What is macrophage migration activated by?

A

Macrophage activation factor (MAF)

Migration inhibition factor (MIF)

29
Q

How can pathogens counteract macrophages?

A

Be phagocytosed but adapt the internal environment so the pathogen can survive

30
Q

What are macrophages released into the blood as?

A

Monocytes

31
Q

What are macrophages called in the liver?

A

Kuppler cells

32
Q

What are the causes of granulomatous disease?

A

Specific infections

Foreign bodies

Specific chemicals

Drugs

Unknown

33
Q

What can granulomatous inflammation cause?

A

Caseous necrosis

Giant cells

34
Q

What is granuloma?

A

Aggregrate of macrophage like cells

35
Q

What is granulation?

A

Important healing process with small blood vessels and connective tissue

36
Q

What is fibrin?

A

Deposited in acute inflammation

37
Q

What is fibrous?

A

Typical scar tissue with collagen
