Acute lymphadenitis

Introduction to acute lymphadenitis More secondary to other purulent infections, such as sputum, athlete's foot and so on. Early clinical manifestations include lymphadenopathy, pain or tenderness, which can be promoted at the beginning. In the later stage, multiple lymph nodes adhere to the lumps, which are difficult to push. The surface skin often has redness and edema, tenderness is obvious, and often accompanied by chills. Fever, headache, general malaise and other symptoms. Lesions are common in the neck, armpits, and groin. Infections of the head, face, mouth, neck and shoulders can cause lymphadenitis in the submandibular and cervical areas; infection of the upper limbs, breast, chest wall, back and ventral wall above the umbilicus causes axillary lymphadenitis; lower limbs, umbilicus, abdominal wall, perineum and buttocks The infection can cause lymphadenitis in the inguinal region. Patients can use antibiotics, and those who have formed abscesses should be cut open in time. Treatment of primary lesions. The disease is in the category of "medication sores" and "sputum abdomen" in Chinese medicine. The disease is caused by visceral stagnation, re-invasive trauma, infection, wind and evil, causing qi stagnation and blood stasis, fire poisoning and clotting; or due to unhealthy diet, spleen transport dereliction of duty, water wet in the tendon, stagnation and heat, The disease is caused by heat injury. If the treatment is not timely, an abscess can be formed. Therefore, early detection, early diagnosis and early treatment are the key to the disease. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific population Mode of infection: non-infectious Complications: abscess

Cause of acute lymphadenitis

Causes

Secondary to purulent infection (60%)

Most of the acute lymphadenitis is secondary to other purulent infections. The local lymph nodes, pain and tenderness caused by the invasion of lymph nodes by the lymphatics in the lymphatics can be promoted in the early stage. In the later stage, multiple lymph nodes adhere to the hard block and are not easy to push. The skin on the surface is red and swollen, and the tenderness is obvious. In severe cases, there are systemic symptoms such as chills, fever, and headache.

Suppurative pathogen infection (40%)

If acute lymphangitis continues to spread to local lymph nodes, or purulent lesions spread to the lymph nodes of the region through the lymphatic vessels, it can cause acute lymphadenitis, infection of the upper limbs, breast, chest wall, back and umbilicus above the abdominal wall Inflammation; lower limbs, abdominal wall below the umbilicus, infection of the perineum and buttocks, inguinal lymphadenitis; head, face, mouth, neck and shoulder infections, lymphadenitis of the submandibular and neck, acute lymphangitis and acute The pathogens of lymphadenitis are often Staphylococcus aureus and hemolytic streptococcus.

Acute lymphadenitis prevention

Need early detection, early diagnosis, early treatment, is the key to this disease.

The most common cause of swollen lymph nodes in children is infection. The enlarged part depends on the location of the infection. The infection of the throat and ears may cause swollen lymph nodes in the neck. The head infection may cause swollen lymph nodes behind the ear. Hands or arms Infection can cause swollen lymph nodes in the armpits; infection of the feet and legs can cause swelling of the inguinal lymph nodes. The most common condition is swelling of the neck lymph nodes. It is easy for the mother to notice this part of the child. rest assured.

For most people, sore throat, cold, inflammation of the teeth (abscess), ear infections or insect bites are the causes of lymphadenopathy, but if the lymph nodes enlarge in the middle of the front of the neck or just above the collarbone You must consider reasons other than infection, such as tumors, cysts or thyroid dysfunction.

Most mothers see a child with a lymphadenopathy in the neck. The first thing that comes to mind is a tumor. This is a natural reaction. The tumor is also a cause of lymphadenopathy in children. However, infection is a more common cause. Blood and urine tests, x-ray examination, skin test and biopsy can confirm the doctor's rash.

Acute lymphadenitis complications Complications

If the treatment is not timely, an abscess can be formed. Therefore, early detection, early diagnosis and early treatment are the key to the disease.

Acute lymphadenitis symptoms Common symptoms Lymph node puncture has grass... Lymph node swelling, lumps, chills, nails, visible horizontal groove spinning

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 push. At this time, the skin is often red, swollen, and tender, and has systemic symptoms such as chills, fever, headache, and fatigue. If not controlled in time, it can form. Abscess.

3, more common in the neck, armpits and groin.

Examination of acute lymphadenitis

1. Laboratory inspection:

The white blood cell count is higher than normal (normal value is 4-10 g/L), the proportion of neutral multinucleated cells increases, and there is a nuclear left shift phenomenon.

2. Cytological examination:

Cytological examination: Since malignant tumor cells are easily detached from the original cells, the tumor cells or tissue granules can be obtained by various methods to identify their properties. The lymphocytes of the disease were examined for infective changes.

Diagnosis and diagnosis of acute lymphadenitis

Diagnose based on

1. In the affected area, the lymph nodes are swollen, tender, local skin is red, swollen, and there may be fluctuations after suppuration.

2, can be accompanied by chills, fever, headache and other systemic symptoms.

Differential diagnosis

Need to be differentiated from acute lymphangitis.

Tubular lymphangitis can be divided into deep and shallow, shallow lymphangitis, one or more "red lines" appear in the proximal side of the wound, hard and tender, deep lymphangitis does not appear red line, but the affected limb appears swelling There is tenderness, both types of lymphangitis can cause general malaise, chills, fever, headache, fatigue and loss of appetite.

Acute lymphadenitis is only local lymphadenopathy and slight tenderness, and often self-healing, heavier, local red, swollen, pain, heat, accompanied by systemic symptoms, through timely treatment, redness can be resolved, But sometimes due to scars and tissue hyperplasia, a small induration can be left; inflammation spreads around the lymph nodes, several lymph nodes can stick together into a mass; can also develop into an abscess, at this time, the pain is aggravated, local skin becomes dark red, edema, tenderness obvious.
