Human demodicosis

Introduction to human Demodex Human Demodex is commonly found in the hair follicles Demodex and the sebaceous gland Demodex, mainly in the hair follicles and sebaceous glands. Severe infections and/or concurrent bacterial infections can cause skin damage and cause Demodex. Human Demodex infections are global, and infection rates increase with age. The diagnosis of Demodex is mainly based on clinical observation. The skin has symptoms such as itching, tingling, flushing, greasy, maculopapular rash, etc. It can also be examined by pathogens, which is easy to diagnose and does not require special identification. The diagnosis of Demodex is mainly based on clinical observation. The skin has symptoms such as itching, tingling, flushing, greasy, maculopapular rash, and pathogenic examination. basic knowledge The proportion of sickness: 0.01% Susceptible people: no special people Mode of infection: non-infectious Complications: rosacea, blepharitis, epidermal cyst

Cause of human Demodex

Mechanical stimulation (10%):

Demodex mites are small, difficult to observe with the naked eye, free to enter and exit the hair follicles, sebaceous glands, corpus callosum, sharp claws, directly damage epidermal cells, and it also feeds on host epithelial cells, sucking epithelial cell contents.

Chemical damage and secondary bacterial infections (25%):

The metabolites, secretions, and decomposition products of the corpus callosum are all foreign bodies. They act as inflammatory mediators and cause inflammatory reactions. When the worms freely enter and exit the hair follicles and sebaceous glands, they can carry pathogenic microorganisms on the surface of the skin, causing pustules. Bloated.

Immunopathology (8%):

At present, this argument is still controversial. Some scholars believe that the insect breaks through the barrier function of hair follicles and sebaceous gland epithelium, which can cause strong I allergic reactions (such as urticaria), persistent stimulation of the worm, causing type IV delayed type hypersensitivity (granulation). Swollen reaction).

Human rickets prevention

The control of human Demodex disease is important in prevention, and prevention of Demodex disease should adopt comprehensive prevention measures:

1 Early detection, correct diagnosis and treatment of patients with Demodex infection;

2 Improve environmental sanitation conditions, develop good hygiene habits, wash basins in the family, towels, etc., often boil, reduce the chance of transmission, take a bath, dip pillows, bedding;

3 Strictly disinfect the beauty, massage and other public places to prevent mutual infection.

Human rickets complications Complications, rosacea, blepharospasm, epidermal cyst

1, sputum rosacea.

2, spastic blepharitis.

3, spastic external auditory canal pruritus.

Demodex can also cause seborrheic alopecia, perioral inflammation, genital itching and other skin diseases, but also with mixed warts, epidermal cysts, basal cell carcinoma, tuberculosis leprosy and so on.

Demodex rickets symptoms common symptoms rosacea pruritus

Demodex mites have the highest detection rate in the forehead, rim, nasal, chin, and mouth of the human face. Common clinical manifestations are rosacea, hemorrhoids, blepharitis, and some patients have external auditory canal, papillitis, genital itching, etc. symptom.

Human rickets

The diagnosis of Demodex is mainly based on clinical observation. The skin has symptoms such as itching, tingling, flushing, greasy, maculopapular rash, and pathogenic examination.

Diagnosis and diagnosis of human Demodex

diagnosis

1, good for adult face, which is obvious in the nose, forehead and cheek.

2, skin lesions similar to seborrheic dermatitis, rosacea, hemorrhoids, pigmentation, speckles, etc., subjective micro-itch.

3, the sebum is extruded, and the human Demodex can be found under the microscope.

Differential diagnosis

The diagnosis of Demodex is mainly based on clinical observation. The skin has symptoms such as itching, tingling, flushing, greasy, maculopapular rash, etc. It can also be examined by pathogens, which is easy to diagnose and does not require special identification.
