impetigo
Introduction
Introduction to impetigo Impetigo, commonly known as "yellow water sore", is a common acute suppurative skin disease. It has the characteristics of contact infection and autologous infection, and is easy to be prevalent in children. The pathogens are mainly coagulated plum-positive Staphylococcus aureus or beta-hemolytic streptococcus alone or in combination. In summer and autumn, the temperature is high, the humidity is high, and the skin is impregnated. It is easy for the bacteria to invade the skin and create favorable conditions for the disease. basic knowledge The proportion of illness: 0.087% Susceptible people: easy to be popular among children Mode of infection: contact spread Complications: acute lymphangitis acute glomerulonephritis
Cause
Cause of impetigo
Bacterial infection (35%):
The pathogens are mainly coagulase-positive Staphylococcus aureus, followed by type B hemolytic streptococcus, a few coagulase-negative white staphylococcus aureus, and staphylococcus and streptococcus mixed infection are not uncommon.
Physical factors (25%):
In some external environments, such as high temperature, sweating and skin impregnation, bacteria can easily multiply on the skin.
Disease factor (30%):
When suffering from pruritic skin diseases such as scorpions, insect bites, dermatitis, and eczema, the barrier function of the skin can be destroyed, which is easy to cause pathogenic bacteria to invade and cause the disease.
Prevention
Impetigo prevention
To prevent impetigo, pay attention to the following points:
· Prevent impetigo, pay attention to clean skin and avoid damage.
· Children's daily utensils and dressing dressings must be strictly disinfected or burned to prevent contact with infection.
· Children can be supplemented with vitamins a, b, c, and if necessary, gamma globulin injection to enhance immunity.
Conditional patients can receive staphylococcal, streptococcal vaccine, or multivalent mixed vaccine injections.
Complication
Impetigo complications Complications acute lymphangitis acute glomerulonephritis
Severe cases are often complicated by lymphangitis, lymphadenitis, and even acute glomerulonephritis.
Symptom
Impetigo symptoms Common symptoms Pustular itching papules blush bullae (with purulent liquid)
1. Conscious itch.
2. The skin lesions are initially papules or blisters, which quickly become pustules with inflammatory redness, scattered around.
3. Occasionally on the face, limbs and other exposed parts.
Examine
Impetigo examination
1. The examination of patients with simple pustules is based on routine blood tests.
2. Examination of patients with high fever and systemic poisoning symptoms may include: routine blood tests, electrocardiogram, blood culture + drug sensitivity test.
Diagnosis
Diagnosis of impetigo
Diagnose based on:
1. Popular in summer and autumn, more common in children and young children, easy to spread, often have lice before the disease, eczema pruritic skin disease.
2. It is good to be exposed to the face, limbs and other exposed parts.
3. The skin lesions are pimples or blisters at first, and quickly become pustules with inflammatory redness.
4. May be associated with lymphangitis, severe cases can cause sepsis or acute nephritis.
Differential diagnosis
Pustular vulgaris can be diagnosed according to the season of the epidemic, age of onset, predilection site and typical purulent sputum. Bullous impetigo and neonatal impetigo are large pustules and strong contagious according to their thin wall. It is not difficult to diagnose, SSSS and deep impetigo can be diagnosed according to their unique skin lesions.
