vesicular distal dactylitis
Introduction
Introduction to vesicular distal finger inflammation Blisteringdistaldactylitis or dermatitishydroa/vesicles/blisterdistalfingers, a rare blistering infection of the palm of the hand, first reported by Hays and Mullard in 1972, mainly For children. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: bacterial infection
Cause
Vesicular distal end
(1) Causes of the disease
The pathogenic bacteria are type B () hemolytic streptococcus, and may also be accompanied by coagulase-positive Staphylococcus aureus infection. Some patients may have lesions in the nasal cavity, around the nostrils, and the pharynx may also be separated from type B (). Hemolytic streptococcus.
(two) pathogenesis
Gram-positive cocci, the bacteria are cultured as type B () hemolytic streptococcus, invading the skin damaged by children's play, causing blisters or pustules.
Prevention
Vesicular distal finger inflammation prevention
1. In the units prone to pyoderma (such as some factories, agricultural machinery stations, primary schools, etc.), extensive publicity and education on the prevention and treatment of suppurative skin diseases, regular preventive inspections, as far as possible to eliminate all factors.
2. Pay attention to skin hygiene, strengthen physical exercise and increase skin resistance.
3. Maintain the integrity of skin function. For skin diseases, especially pruritic skin diseases, timely treatment should be carried out to prevent skin damage and avoid irritation such as scratching and skin friction.
4. Clothes, towels, basins, etc. are prohibited from public use to prevent contact with infection. The patient should be properly isolated. The dressings and contact materials used by the patient should be strictly disinfected or burned. During the illness, it is forbidden to use the liquid to clean the skin lesions. Wash the affected area with tap water to prevent extension.
5. When you are sick, you should ban alcohol or spicy food, and eat less food.
Complication
Vesicular distal inflammatory complications Complications bacterial infection
The main complication of this disease is due to the infection of the skin mucosa after the infection, due to the destruction of skin integrity, it can cause skin bacterial infection or fungal infection due to scratching, usually secondary to low body, or long-term use of immunosuppressants and Patients with fungal infections such as onychomycosis, such as concurrent bacterial infections, may have fever, skin swelling, ulceration, and purulent secretion. Severe cases can lead to sepsis, which should be brought to the attention of clinicians.
Symptom
The vesicular distal end refers to the symptoms of inflammation. Common symptoms There are small blisters on the hands, red pustules, blisters deep in the watch skin.
Mostly blistering or pustules, surrounded by blush, located on the palm of one or several fingers 1 to 3 knuckles, accidentally visible in the nail ditch, consciously itching, no lymphadenopathy and fever, mostly occurred in 2 Children aged ~12 years old can also be seen in adults. A large number of polymorphonuclear granulocytes and Gram-positive cocci are seen in the blister smear, and the bacteria are cultured as type B () hemolytic streptococcus.
Examine
Examination of vesicular distal inflammation
Positive bacterial culture is diagnosed.
Diagnosis
Diagnostic identification of vesicular distal finger inflammation
Diagnosis is based on clinical features and examinations.
Need to be identified with the following diseases:
1. Infant acne impetigo: more than 10 months old infants, itching, negative bacterial culture.
2. Palmoplantar pustular psoriasis: for dense small pustules, can have multiple layers of desquamation, bacterial culture is negative.
3. Others: There is still a need to identify children with acne, sweat herpes, Weber-Cockne type bullous epidermolysis.
