Cause of hemolytic streptococcal gangrene

(1) Causes of the disease

Acute suppurative gangrene caused by hemolytic streptococcus.

(two) pathogenesis

Low immune function, diabetes, poor skin hygiene, and scratching, hemolytic streptococcus invades the skin, breeds and grows, infiltrates deep, leading to acute suppuration, followed by local pain, toxemia, fever and failure symptoms, large skin Necrosis, shedding, necrosis deep into the subcutaneous tissue, the formation of acute suppurative gangrene.

Hemolytic streptococcal gangrene prevention

1. In the units prone to pyoderma (such as some factories, agricultural machinery stations, primary schools, etc.), extensive publicity and education on the prevention and treatment of suppurative skin diseases, regular preventive inspections, as far as possible to eliminate all factors.

2. Pay attention to skin hygiene, strengthen physical exercise and increase skin resistance.

3. Maintain the integrity of skin function. For skin diseases, especially pruritic skin diseases, timely treatment should be carried out to prevent skin damage and avoid irritation such as scratching and skin friction.

Hemolytic streptococcal gangrene complications Complications sepsis and bacteremia

In severe cases, gangrene develops rapidly, producing sepsis and bacteremia. The symptoms of systemic poisoning are serious and can cause life-threatening.

Hemolytic streptococcal gangrene symptoms Common symptoms Ulcer pain Skin necrosis Fever Muscle necrosis Auricular flank cystic cyst

At first, the skin appeared obvious on the skin, the surface was tense and bright, similar to the limited redness of erysipelas, local pain, accompanied by fever and failure symptoms, redness and swelling quickly turned dark red or blue-black and bullae appeared. Soon, the bullae became obvious. Gangrene, large skin necrosis, shedding, necrosis deep into the subcutaneous tissue, the formation of scars after the recovery, severe gangrene development, serious symptoms of systemic poisoning, can cause life-threatening.

Examination of hemolytic streptococcal gangrene

Histopathology: -hemolytic streptococcus is easily isolated from the margin of necrotic tissue.

Diagnosis and identification of hemolytic streptococcus gangrene

The redness quickly turns into dark red or blue-black and bullies appear. Soon, the bullae become a gangrene with obvious gangrene. The skin is necrotic and shedding, and the necrosis is deep into the subcutaneous tissue. The scar is formed later. In severe cases, gangrene develops rapidly, and severe symptoms of systemic poisoning can cause life-threatening. Histopathology: -hemolytic streptococcus is easily isolated from the margin of necrotic tissue.
