Variables that may modify the basic process of inflammation
|
1. Nature and intensity of injury
2. Site and tissue affected 3. Responsiveness of host |
|
Outcomes of acute inflammation
|
1. Complete resolution
2. Healing by connective tissue replacement 3. Progression of the response to chronic inflammation |
|
Usual outcome of acute inflammation
|
Complete resolution of site of acute inflammation to normal
|
|
What happens as acute inflammation is healed by connective tissue replacement?
|
-fibrosis
-occurs after substantial tissue destruction c.t. grows in the area of damage- converts it into a mass of fibrous tissue |
|
When will acute to chronic transition occur?
|
If acute inflammatory response cannot be resolved
Persistent injurious agent Interference with normal processes of healing |
|
Examples of acute to chronic inflammation transition
|
Bacterial infection of the lung:
1. pneumonia- focus of acute inflammation 2. chronic lung abscess- extensive tissue destruction & formation of a cavity |
|
Morphologic hallmarks of acute inflammation
|
-dilation of small blood vessels
-slowing of blood flow -accumulates of leukocytes and fluid in extravascular tissue |
|
Where does the fluid involved in serious inflammaiton come from?
|
Drrived from plasma/secretions of mesothelial cells in peritoneal, pleural, pericardial cavities
|
|
Effusion
|
Accumulation of fluid in peritoneal, pleural, & pericardial cavities
|
|
Skin blister
|
Serous inflammation
|
|
Characteristic of fibrinous inflammation
|
Fibrinous exudate
