bacterial skin disease
Introduction
Introduction to bacterial skin diseases Skin infections are bacterial and fungal infections. The patients are mild and heavy, light and easy to treat, and severely difficult to treat. A common skin infection is Staphylococcus aureus infection, which is clinically manifested as skin blemishes, gangrene, cellulitis, and folliculitis. Fungal infections include various dermatophytosis and skin mucosal candidiasis, such as vulvitis, balanitis, glans erosion, and paronychia. Bacterial skin diseases are bacterial infections of the skin and are classified into primary and secondary. According to the onset of illness, there is often a history of trauma, skin lesions are clear edematous erythema, consciously burning and pain, with systemic symptoms such as fever and the total number of peripheral white blood cells and neutrophils are not difficult to diagnose. It should be differentiated from contact dermatitis, bacillary rash, cellulitis, etc. basic knowledge Sickness ratio: 0.5% Susceptible people: no special people Mode of transmission: partial contact spread Complications: nausea and vomiting
Cause
Cause of bacterial skin disease
Bacterial infection (75%):
Staphylococcus usually causes impetigo, folliculitis, sputum, sputum and the like. Streptococcus easily causes erysipelas and cellulitis, and induces nephritis and arthritis. Skin tuberculosis and leprosy dermatitis.
Skin lesions (25%):
Secondary infections often occur on existing skin lesions, found in specific areas (such as the outer ear) or specific types of skin lesions (such as ulcers), often from Gram-negative bacteria (Proteus, Pseudomonas, Escherichia coli) To.
Prevention
Bacterial skin disease prevention
Bacterial skin diseases generally occur in the face, limbs, etc., such as: impetigo can be rubbed with Baidubang ointment or 0.1% rivanol solution, oral amoxicillin, potassium clavulanate dispersible tablets, etc., usually pay attention Dustproof, use cosmetics as little as possible, do not squeeze by hand, prevent infection.
Complication
Bacterial dermatological complications Complications, nausea and vomiting
May cause a variety of skin-related diseases.
Symptom
Bacterial dermatological symptoms Common symptoms Skin lined up... Blister or bullae damage high heat chills Lymph nodes swollen legs long red vomit vomiting erythema (clear boundary
1. The onset is more urgent, and there are prodromal symptoms such as general malaise, chills, high fever, headache, nausea and vomiting.
2. After a few hours, local edematous erythema appears in the local area. The surface is tense and bright, and it rapidly expands to the surrounding area. Sometimes the blisters may appear on the surface of the skin lesions. The blister wall is thick, the contents are clear or turbid, and the sensation is hot and painful. Lymphangiitis and lymphadenitis.
3. In the face, the erythema starts from one side and gradually spreads and spreads across the bridge of the nose to the cheeks. It forms a butterfly-shaped redness, and the nearby lymph nodes are swollen and painful. Later, it can spread to the scalp and the lower jaw to make the whole face red and swollen. It is difficult to blink because of obvious swelling of the eyelids. Occurred in the calf often have inguinal lymph nodes.
Examine
Bacterial skin disease examination
Bacterial skin diseases are caused by Staphylococcus aureus and/or beta-hemolytic streptococcus infection. Laboratory tests can lead to an increase in the total number of peripheral white blood cells. After the pus smear Gram staining, microscopic examination can be used for preliminary diagnosis according to the morphology, arrangement and staining properties of the bacteria. The pus specimen or venous blood can be used as a bacterial culture to identify the strain and to make a drug sensitivity test.
Diagnosis
Diagnosis and identification of bacterial skin diseases
Bacterial skin diseases are bacterial infections of the skin and are classified into primary and secondary. According to the onset of illness, there is often a history of trauma, skin lesions are clear edematous erythema, consciously burning and pain, with systemic symptoms such as fever and the total number of peripheral white blood cells and neutrophils are not difficult to diagnose. It should be differentiated from contact dermatitis, bacillary rash, cellulitis, etc.
