Ahong's disease
Introduction
Introduction to Ahong disease Ahong disease, also known as ainhum, refers to (toe), or spontaneous toe (dactylolysisspontanea), is an endemic disease in the tropics, due to chronic inflammation of the fibrosis, around the toe (referring to) The linear stenosis finally forms a finger (toe) break. basic knowledge The proportion of illness: 0.0007% Susceptible people: no specific people Mode of infection: non-infectious Complications: swelling, impetigo
Cause
Cause of a Hong disease
Causes:
The cause is unknown, may be related to congenital abnormalities in genetic quality, chronic injury and long-term barefoot walking in the tropics, or congenital hyperkeratosis of the skin, secondary inflammation and fibrosis caused by cleft palate.
Pathogenesis:
The pathogenesis is still unclear, possibly with genetic quality, hyperkeratosis of the skin caused by chronic injury, secondary inflammation and fibrosis of the cleft palate.
Prevention
Ahong disease prevention
The etiology of this disease is not particularly clear, and may have certain correlation with environmental factors, genetic factors, dietary factors, and mood and nutrition during pregnancy. Therefore, it is impossible to directly prevent the disease against the cause.
Complication
Ahong disease complications Complications, swelling, impetigo
The disease is a hereditary disease, the skin is excessively keratinized and the skin integrity is destroyed, so the skin bacterial infection or fungal infection may be induced by the patient's scratching, usually secondary to low constitution, or long-term use of immunosuppressants and nails and nails. Patients with fungal infections, such as concurrent bacterial infections, may have fever, skin swelling, ulceration, and purulent secretion.
Symptom
Symptoms of Ahong's disease Common symptoms Toe (finger) ring narrowing with a spherical inflammation at the distal end of the toe
1. Skin damage begins in the proximal or lateral flexion of the first toe joint. The cleft palate is inflamed or chronically ulcerated, gradually expanding into a ring-shaped narrowing. The distal end of the toe is spherical and connected to the proximal end only one line. After 5 to 10 years of development, it is finally broken off.
2. It is good for the toes, especially the small toes, and the fingers can be invaded.
3. Clinical manifestations of toe (referring to) annular narrowing band, similar to toe.
Examine
Ahong disease check
Clinical skin examination: skin damage begins at the proximal or lateral flexion of the first toe joint. The cleft palate is inflamed or chronically ulcerated, gradually expanding into a ring-shaped narrowing, the toe distal end is spherical, and the proximal end is only A line is connected. After 5 to 10 years of development, it finally broke off naturally.
Diagnosis
Diagnosis and identification of Ahong disease
According to the clinical manifestations, the characteristics of the lesions can be diagnosed.
