ulcerative necrotizing stomatitis
Introduction
Introduction to ulcerative necrotic stomatitis Ulcerative necrotizing stomatitis (necrotizingulcerativestomatitis) is a serious oral gangrenous lesion caused by infection with Vincent spirochetes or Fusobacterium. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific population Mode of infection: non-infectious Complications: oral ulcers
Cause
Causes of ulcerative necrotic stomatitis
Causes:
The main pathogens are Fusobacterium and F. sinensis. These bacteria are inherent in the oral cavity and do not cause disease under normal conditions. When the body has metabolic disorders, immune function is low, resistance is reduced or malnutrition, or the mouth is unhygienic. , the bacteria multiply and cause disease, causing acute necrotizing ulcerative oral lesions.
Pathogenesis:
The pathogen of the disease is Clostridium and spirochete, and a large number of Clostridium and spirochetes are seen on the lesion site. Under normal circumstances, Clostridium and spirochetes are symbiotic in the mouth and are generally not susceptible to infection. However, when the local or systemic resistance is reduced, the two bacteria can be multiplied and become ill, and when the oral hygiene is poor and the nutritional status is poor, the disease is rapid and the lesion is serious. The disease is usually a complex mixed infection, which can be combined with other bacteria, such as streptococci, filamentous bacteria, melanin and other bacterial infections.
Prevention
Ulcerative necrotic stomatitis prevention
prevention:
1, regular physical examination: to achieve early detection, early diagnosis, early treatment.
2, good follow-up: to prevent the disease from getting worse.
3, careful care, supplement protein, vitamins, blood transfusion, energy mixture, etc. to increase resistance, control infection is also very important.
4, enhance physical fitness, improve their own immunity: reasonable feeding, enhance physical fitness, develop a good habit of oral hygiene, for weak children, long-term sick children, especially during the eruption of teeth, it is necessary to strengthen oral care, timely replacement of new toothbrushes , dental appliances, etc., to effectively prevent the occurrence of this disease.
Complication
Ulcer necrotic stomatitis complications Complications, oral ulcers
Destroy the skin of the cheeks and adjacent bones, forming penetrating ulcers, releasing abnormal smells, often leading to death.
Symptom
Ulcerative necrotic stomatitis common symptoms stomatitis oral ulcer
The oral mucosa has a shallow ulcer, which rapidly develops into a gangrene and spreads and expands, thereby destroying the cheek skin and adjacent bones, forming a penetrating ulcer, releasing abnormal smell, and often causing death.
Examine
Examination of ulcerative necrotic stomatitis
Clinical physical examination: shallow ulcers in the oral mucosa, rapidly develop into gangrene and spread and enlarge, thereby destroying the cheek skin and adjacent bones, forming penetrating ulcers, accompanied by odor, and purulent damage caused by local tissue. Outflow of sexual secretions.
Laboratory examination: blood routine examination is often positive, white blood cells increase significantly, and neutrophil increased.
Diagnosis
Diagnosis and differentiation of ulcerative necrotic stomatitis
According to the clinical manifestations, shallow ulcers appear in the oral mucosa, rapidly develop into gangrene and spread, and expand, thereby destroying the cheek skin and adjacent bones, forming penetrating ulcers, releasing the characteristics of abnormal odor, which can be diagnosed.
TCM syndrome differentiation: due to dysentery and accumulation of fire, the remaining poisons attacked, accumulated fire and heat, but the loss of blood is also an important factor in the incidence.
