Inflamed

Introduction Inflammation: refers to the physiological response that a biological tissue is stimulated by trauma, hemorrhage, or pathogen infection. These include symptoms such as redness, fever, and pain. A local tissue reaction dominated by inflammatory factors that cause damage to the body. Mainly manifested as tissue deterioration, exudation and tissue cell proliferation. Clinically very common, inflammatory facial often manifests as redness, swelling, heat, pain and dysfunction, accompanied by systemic manifestations such as fever, leukocytosis or decreased, systemic mononuclear phagocytic system hyperplasia, local lymphadenopathy and splenomegaly Great.

Cause

Any factor that causes tissue damage can be the cause of inflammation, the inflammatory agent. Can be summarized into the following categories:

(a) biological factors

Bacteria, viruses, rickettsia, mycoplasma, fungi, spirochetes and parasites are the most common causes of inflammation. Inflammation caused by biological pathogens is also known as infection.

(2) Physical factors

High temperature, low temperature, radioactive materials, ultraviolet rays, etc. and mechanical damage.

(3) Chemical factors

Exogenous chemicals such as strong acids, strong bases and turpentine, mustard gas, etc. Endogenous toxic substances such as decomposition products of necrotic tissue and metabolites such as urea accumulated in the body under certain pathological conditions.

(four) necrotic tissue

Tissue necrosis caused by ischemia and hypoxia is a potential inflammatory factor.

Laboratory tests include isolation and culture of bacteria, fungi, viruses and mycobacteria, including blood and other collectable body fluids, total blood counts and antibody titrations (eg typhoid fever, brucellosis and certain viral diseases). For the diagnosis of certain diseases (such as infective endocarditis), it may be necessary to collect blood several times, such as 2 to 3 times a day, for isolation and culture. For the diagnosis of protozoal diseases (such as malaria), direct blood examination is required. Increased antibody titers can diagnose many infectious diseases, but the interval between serum samples should be regular. New, more specific immunological and molecular biology techniques (such as PCR) established in recent years may also be helpful in diagnosis.

Differential diagnosis

1. Acute inflammation: short duration, often only a few days, usually no more than one month, mainly exudative lesions, inflammatory cells infiltrated with neutrophils.

2. Chronic inflammation: It lasts for a long time, from several months to several years. The lesions are mainly proliferative changes, and the inflammatory cells infiltrate mainly lymphocytes and monocytes.
