Introduction
Introduction to lymphitis Lymphadenitis is caused by bacteria invading the lymph nodes along the lymphatic vessels. However, not everyone will develop lymphadenitis when they encounter bacterial infections. This disease is only likely to occur when the body's resistance is reduced. Long-term malnutrition, anemia, and other chronic diseases can cause lymphadenitis after infection with bacteria. The bacteria that cause this disease are often Staphylococcus aureus and hemolytic streptococcus. In people's lives, people often have a cold or other infection, neck, ear, armpit or groin can appear as a nodule of glass sphere size, local redness and tenderness, according to the hard, that is, suffering from lymphadenitis. basic knowledge The proportion of illness: 0.003% Susceptible people: no special people Mode of infection: non-infectious Complications: cervical lymph node metastasis, skin mucosal lymph node syndrome
Cause
Cause of lymphitis
Low immunity (35%)
Not everyone will develop lymphadenitis when they encounter bacterial infections. This disease is only likely to occur when the body's resistance is reduced. Long-term malnutrition, anemia, and other chronic diseases can cause lymphadenitis after infection with bacteria.
Bacterial infection (45%)
The pathogens are mainly streptococcus and Staphylococcus aureus. When the human body is accidentally injured or secondary to other purulent infections, the purulent bacteria invade the local lymph nodes along the lymphatic vessels, which can cause acute inflammatory lesions. The main pathological changes are lymph node congestion, edema, and solidified lymph and bacteria.
Secondary infection (15%)
Lymitis is often secondary to other purulent infections, caused by pathogenic bacteria invading the lymph nodes along the lymphatic vessels.
Prevention
Lymphitis prevention
Active prevention and treatment of primary lesions. When suffering from phlegm and athlete's foot, it should be avoided; active treatment, if the treatment is not timely, the disease may occur secondary to infection. Since lymph fluid is a lymph node that is grouped in a specific area, a primary infection of a certain site can only cause lymphadenitis in a certain part. Therefore, the disease occurs mostly in the neck, underarms and groin. After lymph node infection, it can cause inflammation around the lymph nodes, adhesions into a mass, and can develop into an abscess. Patients should pay attention to rest, light diet, and actively treat the primary lesion.
Complication
Lymphitis complications Complications, cervical lymph node metastasis, skin mucosal lymph node syndrome
Cervical lymph node metastasis, skin mucosal lymph node syndrome.
Symptom
Symptoms of lymphitis Common symptoms Cervical lymphadenopathy, low fever, night sweats, lymphatic obstruction
Cervical lymph node tuberculosis due to tuberculosis invading the cervical lymph nodes caused by chronic specific infections more common in children young tubercle bacilli mostly through tonsil caries invasive tuberculosis lesions secondary to the lungs or bronchus only when the body's disease resistance is low.
Its symptoms are:
1. The neck side (one side or both sides) of the enlarged lymph nodes of different sizes is isolated solitary nodules. Painless and smooth, movable lesions continue to develop lymph node fusion into a block of irregular mobility, late lymph node necrosis and liquefaction formation Cold abscess has a fluctuating sensation. After the rupture of the abscess, the sinus secretion is thin and contains a cheese-like substance. The ulcer surface is pale or the dark red skin is sneaked for a long time.
2. There are often symptoms of chronic poisoning such as low heat, night sweats, lack of energy and weight loss.
Examine
Examination of lymphitis
1. The secretions in the purulent sinus or the sinus are examined by smear or concentration method, and the tuberculosis can be detected by staining with acid-fast bacilli. The erythrocyte sedimentation rate is measured mildly or moderately, and the tuberculin intradermal test (OT test) is positive for diagnosis.
2. Ultrasound can be used to diagnose the extent of tuberculous lymphadenitis.
3. The application of lymphatic angiography or isotope examination can help the differential diagnosis of lymphadenopathy.
4. Laboratory examination: blood routine leukocytosis.
5. If necessary, it can be confirmed by biopsy.
Diagnosis
Lymphitis diagnosis and differentiation
The diagnosis is performed by referring to the physical examination results of the examination of the body.
1. Early lymphadenopathy, pain and tenderness, can be active.
2. In the later stage, multiple lymph nodes adhere to a hard block, which is difficult to promote. The skin is often red, swollen and tender, and has systemic symptoms such as chills, fever, headache, and fatigue. If not controlled in time, an abscess can be formed. .
3. More common in the neck, armpits and groin.
