Ringworm

Brief introduction Tineabarbae is a superficial dermatophytosis that occurs in the roots of the mandible. The disease is distributed all over the world. It is more common in Europe, America and other places. It is more common in ethnic minority areas in Xinjiang, especially in agriculture and livestock. Close contact. basic knowledge The proportion of sickness: 0.2% Susceptible people: male Mode of infection: contact spread Complications: Onychomycosis

Sickness

(1) Causes of the disease

There are many pathogenic fungi causing this disease, such as T. violaceum, T. rubrum, T. metagrophytes, and Gypsum-like Trichophyton (T .gypseum) and M. canis, M. gypseum, etc., also reported by E. flocsum, but rare, pathogens passed directly Or indirect contact transmission, most of which is dyed at the barbershop, local topical corticosteroid preparation is one of the important incentives.

(two) pathogenesis

T. violaceum, T. rubrum, T. metagrophytes, T. gypseum and M. canis ), gypsum-like microsporum (M. gypseum), etc., the former two can cause shallow damage, the latter two cause deep damage, mainly in the side of the neck, the beard hair follicle fungal hair follicle inflammation.

Sputum prevention

Improve the prevention and treatment organizations at all levels, carry out mass publicity and education, widely publicize the infection routes and methods of infection of dermatophytosis, preventive measures and the need for timely and thorough treatment, educate the masses to develop good hygiene habits, and abide by health Health care system, etc.

Carry out the principle of prevention and prevention, and implement a series of physical examination, isolation, management and treatment systems, and strive for early detection, early diagnosis and early treatment.

1. Regularly check and establish a health care system for children in primary schools and kindergartens, as well as public places such as barber shops, baths, and swimming pools. If you find sputum disease patients, you must conduct fungal examinations for early diagnosis.

2. Patients who have been diagnosed should be treated immediately and patients should be encouraged to adhere to treatment. Strict examinations should be carried out for children enrolled or enrolled. If they are found to be head lice, they should be isolated from other children. They must be tested after two curative tests (including direct microscopic examination and culture of fungi). Enrollment or school.

3. For patients' clothes, bedding, shoes, hats, pillowcases and other appliances and equipment used in barbershops, bathrooms, swimming pools, etc., they should be disinfected regularly. If the conditions permit formaldehyde (formalin) disinfection (250 ml of formalin per cubic meter volume, temperature 58-59 ° C, time 2.5 h), the hair and scales with fungi must be burned.

4. The affected animals should be inspected at the same time and treated appropriately. The management must be closed before the diagnosis is confirmed, and the breeding place should be disinfected frequently. In the kindergarten, animals such as dogs and cats should be promoted.

5. The cure should include clinical examination and mycological examination of the diseased material. In case of suspicious circumstances, it should be repeated.

6. All hospitals or health care units should gradually establish an outpatient clinic for dermatophytosis and give patients treatment convenience.

7. All medical colleges and medical institutions should conduct research work on dermatophytosis, especially study on effective prevention and treatment methods for head lice and hand, foot and ankle, and vigorously cultivate health workers and professional nurses with dermatophytosis.

Sputum complications Complications

Because the disease is a fungal infection, mainly caused by skin damage, scratching the skin can spread the fungus to other places, causing fungal infection of the skin. If the nail is accompanied by a fungal infection, it will cause onychomycosis. For patients with broken skin, purulent secretion may be caused by bacterial infection, often accompanied by fever, and C-reactive protein and blood picture are obviously increased.

Sputum symptoms common symptoms hair loss pustules sputum nodules scales

Occurs in one side of the neck and the lower jaw beard, the clinical manifestations are mainly in one side of the neck, the fungal folliculitis of the hair follicles of the beard, clinically can be divided into two types:

Shallow in type: similar to body phlegm, the damage is clear, the center has desquamation, there are mild purulent follic inflammatory small pustules around, the affected part of the beard is dry, loose, often broken, falling off.

Deep in type: similar to purulent sputum, the damage is slow nodules, gradually develop, merge with each other, can form ulcers, local infiltration is extensive, skin inflammation is obvious, the beard is loose, easy to pull out, and the opulent hair follicle can be discharged.

Consciously itchy, deep in the type of people have tenderness, stubborn nature, often long-lasting.

Scratch inspection

1. Fungal examination: It is a method of direct microscopic examination to find hyphae and spores for preliminary diagnosis.

2. Indirect immunofluorescence assay: an antibody that binds to an antibody (herein referred to as a primary antibody) is incubated with a cell, and an antibody corresponding to the primary antibody (ie, an anti-antibody) is used (herein referred to as a secondary antibody). The fluorescein molecule coupled to the secondary antibody was incubated with the cells and observed under a fluorescence microscope.

3. Fungal culture inspection: It is a method of cultivating a fungus and identifying the fungus of the fungus, and then performing targeted treatment on the disease caused by the fungal infection.

4. Dermatological microscopy: The hyphae and spores are found by direct microscopy for initial diagnosis. The culture method determines the strain according to the characteristics of the colony and the morphology under the microscope.

5. Skin smear microscopy: It is an examination method for checking the presence of bacteria in blood, urine, cerebrospinal fluid, pleural fluid, pericardial fluid and peritoneal fluid.

Diagnostic identification

diagnosis

According to the clinical manifestations, it is mainly located in one side of the neck, fungal folliculitis of the hair follicles of the beard, direct examination of the disease and pus, culture and fluoroscopy can confirm the diagnosis.

Differential diagnosis

It should be differentiated from common sores and impetigo. Both of them are bacterial infections. The former must be loose, but not broken. The latter is more common in children. Adults are rarely seen, and beards are not invaded. Fungal examinations can be identified.
