acute simple pharyngitis
Introduction
Introduction to acute simple pharyngitis Acute simple pharyngitis (acutesimplepharyngitis) is an acute inflammation of the pharyngeal mucosa and submucosal tissue, and pharyngeal lymphoid tissue is often involved. The early stage of inflammation can be limited to a certain part, and the entire pharyngeal cavity can often be involved as the disease progresses. The disease is more common at the turn of autumn and winter and winter and spring. The cause is mainly viral infection and bacterial infection. It is often infected by droplets or contact. In addition, cold and wet and weakened body resistance (such as fatigue, excessive alcohol and tobacco) are often the cause of the disease. The disease can also be secondary to a cold or acute tonsillitis. According to the medical history, clinical manifestations and pharyngeal examination, the disease is easy to diagnose, but it should be distinguished from the prodromal symptoms or complications of acute infectious diseases, especially in children, in addition to the need for hematologic angina Identification of inflammation, the severity of this disease is related to a variety of factors. If it is a virulence bacterial infection, the total number of white blood cells and neutrophils in the surrounding blood is high, and its systemic symptoms are severe, which is a clear pathogen. It is also very important to use throat swab culture and bacterial susceptibility test for antibody determination and immune function measurement. basic knowledge The proportion of illness: 8.3% Susceptible people: no specific population Infection mode: more infection by droplets or contact Complications: sinusitis laryngitis acute nephritis
Cause
Acute simple pharyngitis
Hemolytic streptococcus (30%):
Hemolytic streptococcal infection can cause respiratory and cardiac system diseases, and its infection mechanism has not yet been clearly stated, but it can also cause rheumatic fever. Rheumatic fever is a common recurrent episode of acute or chronic connective tissue inflammation caused by infection with group A hemolytic streptococcus, mainly involving the heart, joints, central nervous system, skin and subcutaneous tissue.
Staphylococcus (30%):
Staphylococcal disease is mainly an acute or chronic infectious disease caused by Staphylococcus aureus. It is often clinically characterized by various types such as arthritis, tenosynovitis, footpad swelling, umbilical inflammation and staphylococcal sepsis. Caused a large loss to the poultry industry. The typical Staphylococcus aureus is round or oval, often arranged in a single, paired or grape-like manner, Gram-positive, no flagella, no capsule, no spores, and good growth on common medium.
Acute infectious diseases (30%):
Infectious diseases are characterized by pathogens, infectious and epidemic, and often immunogenic after infection. Some infectious diseases are seasonal or local. The classification of infectious diseases has not been unified. Some people are classified according to pathogens, and some are classified according to the route of transmission. The prevention of infectious diseases should adopt comprehensive measures that take the lead in cutting off the main communication links.
Prevention
Acute simple pharyngitis prevention
1, the general prognosis is good, but infants and young children are poor, so for infants and young children, we must pay more attention.
2. Require bed rest and shelter from the wind.
3, avoid all spicy, seafood, hair and high-fat foods, sweets.
4, drink plenty of water and liquid drinks.
5, carefully carry out pharyngeal spraying and timely medication.
Complication
Acute simple pharyngitis complications Complications, sinusitis, laryngitis, acute nephritis
When the body's resistance is low or the treatment is not timely, the spread of inflammation can cause complications such as otitis media, sinusitis, laryngitis, tracheobronchitis and pneumonia. If the pathogen or its toxin invades the blood circulation, such as septic pharyngitis, systemic and local symptoms. Severe, can be complicated by acute nephritis, rheumatic fever and sepsis.
Symptom
Acute simple pharyngitis symptoms Common symptoms Lymph node swelling, sore throat, throat, mucus, throat, tingling, itching, pharynx, congestion, nasal congestion, pharyngeal burning, appetite, loss of earache
According to the medical history, clinical manifestations and pharyngeal examination, the disease is easy to diagnose, but it should be distinguished from the prodromal symptoms or complications of acute infectious diseases, especially in children, in addition to the need for hematologic angina Identification of inflammation, the severity of this disease is related to a variety of factors. If it is a virulence bacterial infection, the total number of white blood cells and neutrophils in the surrounding blood is high, and its systemic symptoms are severe, which is a clear pathogen. It is also very important to use throat swab culture and bacterial susceptibility test for antibody determination and immune function measurement.
The pharyngeal mucosa is swollen and swollen, the secretion of mucous glands is increased, and the serous fluid is exuded. Therefore, the mucosal surface is covered with a thick mucous secretion, and there are granular leukocyte infiltration and lymphocyte infiltration around the submucosal blood vessels and glands, and the lymphatic tissue of the pharynx is involved. Make lymphoid follicles enlarge.
The onset is more urgent, often accompanied by acute rhinitis, initial pharyngeal dryness, itching, slight pain, burning sensation and foreign body sensation, severe with fever, headache, loss of appetite and general malaise, sore throat gradually worsen, affecting swallowing, Do not dare to eat, inflammation involving the pharyngeal side beam, can occur severe radioactive ear pain and neck pain, resulting in limited head and neck activity, pharyngeal examination revealed acute congestion and edema of the mucosa, soft palate and uvula swell swelling, speaking Often nasal, the posterior pharyngeal lymphoid follicles and lateral redness and swelling, submandibular lymph nodes and tenderness.
Examine
Examination of acute simple pharyngitis
In the pharyngeal examination, acute congestion and edema of the mucous membrane can be seen. When the soft palate and the uvula swell are obvious, the voice is often nasal, the lymphatic follicles and the lateral redness of the posterior pharynx are high, and the submandibular lymph nodes are swollen and tender.
In order to clarify pathogenic bacteria, throat swab culture and bacterial susceptibility test are often used. It is also very important to carry out antibody assay and immune function measurement.
Diagnosis
Diagnosis and diagnosis of acute simple pharyngitis
It should be noted that it is different from the prodromal symptoms or complications of acute infectious diseases, especially in children. In addition, it needs to be differentiated from hematological angina.
