Erythrasma
Introduction
Introduction to Hung Hom Red peony is a superficial skin superficial infection caused by Corynebacterium genus Corynebacterium, which is prone to skin friction. The main damage to the skin is a patch with a clear boundary and irregular edges. The color of the lesion varies according to the length of time, and begins to appear red, then brown or reddish brown, and the surface may be accompanied by scales. It is common in the skin of the groin where the thigh root is in contact with the scrotum, the axilla, the hip joint, the lower breast, and the fourth to fifth. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: Staphylococcal infection Chlamydia infection Anaerobic infection
Cause
Cause of red dragonfly
Causes:
Red scorpion was once thought to be caused by actinomycetes. Corynebacterium minutissimum has been isolated from the scales of red carp. Recently, it has been confirmed by electron microscopy that the coryneform bacterium is a pathogen of red peony. Bacillus, a diphtheria-like bacterium, positive for Gram stain, often parasitic on the nose, pharynx, eyes, external auditory canal and skin surface of normal people. When the part is warm and humid or skin damage, the bacteria invade the stratum corneum and cause infection.
Pathogenesis:
Corynebacterium is often parasitic on the nose, throat, eyes, external auditory canal and skin surface of normal people. When the part is warm and humid or the skin is damaged, the bacteria invade the stratum corneum and cause infection.
Prevention
Red dragonfly prevention
Keep it clean and hygienic, take a bath and wash the vulva. Bathing with boric acid bath soap, sulfur bath soap, sandalwood bath soap and other medicated soaps to prevent the occurrence of this disease. Active treatment, avoiding scratching. The underwear is washed and changed frequently, and boiled and disinfected with boiling water.
Complication
Red plaque complications Complications Staphylococcus infection Chlamydia infection Anaerobic infection
The disease is easy to relapse after being cured. Red mites can recur within 6 to 12 months and require a second treatment. Other bacterial infections or fungal infections caused by scratching are usually secondary to low body weight, or long-term use of immunosuppressive agents and fungal infections such as onychomycosis.
Symptom
Red sputum symptoms Common symptoms squamous thigh erythema pruritus anal itching
Damage is a patch with a clear boundary and irregular edges. It starts to turn red and then turns brown. The new damage is smooth, the older damage is wrinkled or there are a lot of squama-like scales. It is common in the skin of the inguinal region, the axilla, the hip joint, the lower breast, the fourth to the fifth toe, etc., which are in contact with the thigh and the scrotum. Often there are no symptoms, but it is susceptible to frictional irritation in the groin, which can cause itching and mossy changes. If the infection affects the skin around the anus, it can cause anal itching.
There is also a generalized red sputum, the skin lesions are clear red-brown patches, widely distributed in the trunk and limbs. This type of red mites is more common in patients with diabetes and other debilitating diseases. Montes believes that diabetes may be a trigger for red snapping.
Examine
Red dragonfly inspection
Laboratory examination: Scaling the smear on the lesion, and staining with Gram or adding 10% potassium hydroxide to the bacteria and hyphae. Colonies appeared after 18 to 36 hours of culture in a tissue culture medium containing 20% calf serum and 2% agar, and coral red fluorescence was observed under Wood's lamp.
Diagnosis
Red sputum diagnosis
diagnosis
1. Gender: More men than women.
2. The site of good hair: the inner thigh, the armpit and the friction under the female breast.
3. Characteristics of rash: Brick red or yellow-brown patches with clear boundary, covered with scaly scales, generally no symptoms. Wood's lamp is orange or coral red.
Differential diagnosis
1. Femoral hernia: The inflammatory reaction is more obvious, there may be blister formation, the boundary is clear, the edge is uplifted, and the scaly fungus is positive.
2. Facial plaque: occurs in the neck, upper part of the trunk, skin lesions are small spots, no erythema, scaly fungus check positive.
