ACUTE INFLAMMATION AND CHRONIC INFLAMMATION Fibrinous inflammation; due to increased vessel permeability with deposition of a fibrin-rich exudate Example- fibrinouspericarditis Staph aureus contains coagulase which cleaves fibrinogen to fribrin and traps bacteria and neutrophils Cont, 3

pn. bmj. com Tissue sample from skin biopsy (magnification ×40, haematoxylin phloxine saffron stain) illustrates a subcutaneous arteriole with fibrinous thrombus (arrow) There is no significant associated inflammation
Developmental defects of oral and maxillofacial region Fibrinous exudates may be removed by fibrinolysis and clearing of other debris by macrophages However, when the fibrin is not removed, it may stimulate the ingrowth of fibroblasts and blood vessels and thus lead to scarring
PowerPoint Presentation Stage of Resolution : Begins by 8th to 9th day – if no chemotherapy With antibiotic therapy- 3rd day Gross - Solid fibrinous exudate enzymatic action liquefied - Process of softening begins centrally spreads to periphery Microscopic examination i) Macrophages are predominant cells Many macrophages contain engulfed neutrophils and debris ii
Eye infections - University of Nairobi The eyeball is protected anteriorly by the eyelids And contained in the orbit Predorminant organisms Diphtheroids S epidermidis Non hemolytic strep The infections could be:- Acute Chronic Primary secondary Conjunctivitis is the most common ocular inflammation Clinical manifestations-hyperemia,secretion –due to exudates of inflammatory cells
PowerPoint Presentation The foundation principles in the management of the infected surgical site are (1) open and drain the incision, (2) debride fibrinous debris and necrotic soft tissue, (3) remove foreign bodies, (4) implement antimicrobial management as needed, and (5) manage the open wound
