Intraungual onychomycosis
Introduction
Introduction to intrathyroid mycosis The deck infection caused by the dermatophytes of Trichophyton rubrum and Trichophyton rubrum, the clinically invaded deck is diffuse milky white, and the nail bed is keratinized and thickened. Antifungal treatment can be given. basic knowledge The proportion of sickness: 0.01% Susceptible people: no special people Mode of transmission: contact sexual transmission Complications: paronychia
Cause
The cause of intrathyroidosis
(1) Causes of the disease
Deck infection caused by dermatophytes, a newly discovered type of deck infection.
(two) pathogenesis
Deck infection caused mainly by Trichophyton rubrum and Trichophyton rubrum.
Prevention
Prevention of intrathyroidosis
Population prevention: Prevention of hyperthyroidism is to remove the source of infection, that is, to cure body lice, femoral hernia, hand sputum and athlete's foot. This is the most active preventive measure for preventing hyperthyroidism. For the prevention of hyperthyroidism, see the light sputum.
Personal prevention:
Primary prevention
(1) Pay attention to personal hygiene, develop good hygienic habits of washing hands, washing feet, and trimming the toes. People with more sweat should wear more breathable shoes and can hold the feet to keep the feet. Dry, or wear mildew shoes, socks.
(2) Those who have suffered from femoral hernia or hand, foot and ankle should be treated actively until they are completely cured to avoid cross-infection.
(3) Do not develop the habit of lameness and lameness, especially for patients with athlete's foot.
(4) For those with hand, foot and ankle, in order to prevent the infection of the nails, apply a 30% glacial acetic acid solution on the nails 2 to 3 times a week.
2. Secondary prevention
The treatment of hyperthyroidism should be treated concurrently with concurrent hand and foot spasm, and it needs long-term patient treatment. The hyperthyroidism activity fungus is hidden deep in the back end of the nail. Generally, the drug of the external hemorrhoids does not reach the affected area, so it is difficult to cure. The maintenance layer (bad armor) is removed, and then the antifungal drug is applied externally, so that the drug easily reaches the affected area.
(1) Generally, a quick blade can be used to cut the diseased part of the diseased piece every day, scrape it off, prevent it from bleeding or causing pain, and then lick 30% glacial acetic acid solution or 5% iodine, until the pain is slightly felt, indicating that the drug has arrived. The bottom layer, 1 or 2 times a month, for several months, until the disease is removed, the normal newborn A is fully grown.
(2) It can also be soaked in 10% ice vinegar solution several times a day, but the effect may be slightly slower.
(3) Pulling therapy
1 Use 30% ~ 40% urea hard plaster on the diseased nail, every 4 to 5 days to replace, the disease can gradually soften, the deck and the nail bed separated, making it easy to remove, if not successful, can be repeated.
2 replace the urea plaster with salicylic acid lactic acid ointment.
3 local anesthesia surgery, pulling the wound with Vaseline gauze if necessary, after 1 week, first apply 3% salicylic acid ointment, then gradually increase the concentration, and finally use compound benzoic acid ointment and iodine alternately, until the new one grows out.
Complication
Complication of intrathyroid mycosis Complications
It can be complicated by paronychia, empyema, ingrown toena, necrosis at the end of the digit.
Paronychia (paronychia) is an inflammatory reaction involving skin wrinkles around the nail. It is characterized by acute or chronic suppurative, tender and painful periungual tissue swelling caused by nail folds and abscesses. When the infection becomes chronic, there is a transverse sputum at the bottom of the methyl group, and new sputum appears with recurrence. Paronychia has been invaded under the armor to form a sub-abdominal abscess, intubation combined with infection, should be removed nail drainage.
Dry toe necrosis is mainly seen in diabetic patients.
Symptom
Symptoms of intrathyroid nail fungus Common symptoms Toe nails in the toenails are thick and brittle and many cracked fingers are stiff and painful.
The invaded deck was diffusely milky white, with a glossy surface, a normal thickness, and a hornless thickening of the nail bed. The deck was closely connected to the nail bed and there was no separation. The fungus invades the nail, and after the deck grows, it can secrete protease to break down the keratin, destroy the nail tissue, and cause the shape, texture and color of the nail to change, which makes the nail beautiful and damaged. Especially for many young people, many patients will suffer from nail fungus. Shrink your hands. Our daily work and life are inseparable from the help. Once the fungus invades and suffers from onychomycosis, the choice of work is limited; the nail growth has a protective effect at the end of the hand, and once it is sick, the hand will easily be injured by the collision and the function of the finger is impaired. In severe cases, it may cause pain. Once it is traumatized, the pathogenic bacteria are prone to long-term drive, which leads to complications such as paronychia, nail bed inflammation and finger pyoderma. It is suitable for patients with serious systemic symptoms such as erysipelas or cellulitis. .
Examine
Examination of intrathyroid nail fungus disease
The pathogenic bacteria are mainly Trichophyton rubrum, and can also be caused by Trichophyton rubrum, both of which have the characteristics of keratin.
A tissue PAS staining shows a large number of fungal hyphae in the umbrella deck. The hyphae are parallel to the deck, penetrate the entire deck, and branch vertically and horizontally in the deck. The nail bed has no inflammation, and is closely connected with the lower deck, and the sterile silk in the nail bed.
Diagnosis
Diagnosis and diagnosis of intrathyroidosis
According to the change of the deck, the direct microscopic examination of the fungus of the nail tissue and the fungal culture can be diagnosed.
It should be differentiated from the distal subungual onychomycosis caused by Trichophyton rubrum.
