Study Notes

Chronic Inflammation

Chronic inflammation is characterized by prolonged tissue response and persistent inflammation.
It often involves lymphocytes and macrophages, unlike acute inflammation which predominantly features neutrophils.
Plasma cells, derived from B lymphocytes, produce antibodies essential for the immune response during chronic inflammation.
Giant cells form from fused macrophages and are indicative of chronic inflammation, often seen in granulomatous conditions.

Acute Inflammation

Acute inflammation is marked by rapid onset and is typically characterized by the presence of neutrophils.
It includes signs like redness, swelling, heat, and pain, contrasting with the indolent nature of chronic inflammation.

Types of Fluid in Inflammation

Serous fluid accumulation is common in serous inflammation, characterized by clear fluid in serous cavities.
Fibrinous inflammation involves the formation of fibrin-rich exudate, which is essential for hemostasis but can lead to tissue adhesion.
Catarrhal inflammation features increased mucous production and is often seen in respiratory tract infections.

Special Types of Inflammation

Hemorrhagic inflammation is characterized by the presence of red blood cells in the exudate, indicating vascular damage and potential tissue necrosis.
Necrotizing inflammation is distinguished by the irreversible cell death of tissues involved and often has a fast progression.
Allergic inflammation is associated with hypersensitivity reactions and typically includes a high number of eosinophils.

Histopathological Features

Fibrinous exudate is linked to serofibrinous inflammation and appears as a thick, yellowish coating on affected tissues.
The main differentiator of necrotizing inflammation from other acute inflammation types is the significant tissue destruction it causes without the production of pus.
In hemorrhagic inflammation, it's important to note the presence of extensive bleeding without typical acute inflammatory signs, such as significant neutrophil infiltration.
