boil is caused by what the?

infection and skin dirty, scratches, high ambient temperature or lower the body resistance to infection-related. Boils can occur in any follicles of the skin area, often to the head, face, neck, armpits and buttocks so often by the friction of the parts is more common.

(a) causes

boil the pathogenic bacteria Staphylococcus aureus based, Streptococcus, Staphylococcus epidermidis, are also caused by the disease. Local and systemic skin's resistance to infection is reduced mainly due to Benbingfasheng, so infants, malnutrition, diabetes is a good risk of this disease. Dirty skin, skin abrasions, high ambient temperatures often lead to local infection such as the direct cause.

(B) the pathogenesis

bacteria invade the hair follicle and their sebaceous glands and sweat glands, in hair follicles and surrounding tissue multiply rapidly, producing toxins, causing local tissue degeneration, necrosis, and the center of the formation of boils, the performance of local congestion, exudation, induration. Aggregation of neutrophils to the damaged body tissue cells and bacteria to be destroyed, and he gradually necrosis and dissolution, the formation of abscesses in the dermis. Due to Staphylococcus aureus, coagulase contain toxins, so the formation of pus bolt, protruding outward. Swelling and induration clinically visible in the center of a yellow-white pus plug. This is Staphylococcus aureus infected lesion characteristics. Ulceration after discharge pus, abscess gradually by the new fibrous tissue repair and healing.


boil the early symptoms?

1. redness, swelling, heat, pain summary, cylindrical cone.

2. inflammation to the development of nodules increases, the pain intensified.

3. A few days later nodules central necrosis, abscess formation, dissolution, soft induration, pain relief, the central pus head most of the self-rupture, discharge pus, inflammation subsided recovery.

4. furuncle usually no obvious symptoms, but if the blood flow occurred in the rich parts of the body resistance weakened, it can cause discomfort, chills, fever, headache and loss of appetite and other symptoms of toxemia.

5. Facial Boil such as intracranial infection, facial swelling and severe, may be associated with chills, fever, headache, sinus infections and other embolization.

boil because of location, severity of different clinical manifestations may vary.

local swelling and pain sclerosis: no systemic symptoms of early disease and more, only infection redness, swelling, pain, range of not more than 2cm in diameter, small nodules gradually enlarged, as papules bulge. A few days later lesions extended about 3 ~ 5cm, nodules gradually softened, the center was white, a slight touch of the fluctuations; then ulceration pus, and the emergence of yellow-white pus plug. Pus bolt off, pus shed, the inflammation subsides and healing. There is no pus boil bolt (the so-called headless boil), since the collapse a bit late, need to find ways to promote its pus discharge (Figure 2 ).

fever, swollen lymph nodes: furuncle serious infection, the local area of ​​the lymph nodes, tenderness, and may be associated with body heat, and sometimes lymph node abscess formation.

nose, upper lip and around (called "dangerous triangle") of the surface boil, add or pushed in touch, the bacteria via the angular vein, ophthalmic vein into the brain, causing intracranial suppurative infection. At this point may have fever, headache, vomiting, consciousness disorders.

early follicular redness, swelling, heat, pain, induration. After the white purulent center, there is volatility. May be associated with systemic fever, elevated white blood cell count and differential count.

how to prevent boils?

boil is born of acute suppurative superficial skin disorders, widely available health, children, young people more common. "Surgical management case" that: "boil persons, birth processes, floating red rootless feet, swollen found in the skin, only the width of an inch, there is less pain, a few days later Microsoft, thin peel, the beginning of the blue water, the latter from breaking the pus out of. "The disease occurs in the summer and autumn, protruding roots shallow, swelling potential limitations, lift the red pain, mostly in the range of about 3cm, easily swollen, easy to collapse, Yi Lian. Early can be divided into a head, without the first two kinds of general light and easy to cure the symptoms, so the saying goes, "no boil the size of a pus like." ;;; ;;;;; ;;;;; ;;;;; But also due to the formation of improper treatment or care "mole cricket boils," or repeated seizures, lack of disunion. Multiple furunculosis ", is difficult to cure.


boil precautions before treatment?

attention to the skin clean, timely replacement of underwear and avoid skin injuries, especially in the summer, to bathe, wash your hair, hair, changing clothes, nails, children in particular should pay attention. With honeysuckle and wild chrysanthemum Jiantang tea. Boil the surrounding skin should be kept clean and coated with 70% alcohol to prevent infection spread to nearby hair follicles.

boil Chinese medicine treatment methods

total boil caused by the toxic heat treatment to detoxify the basic principles.

A Differential Treatment:

1. Heat toxin Accumulation card: lesion processes, such as cone, burning pain, or fever, thirst, tongue pink, yellow fur, rapid pulse. Detoxification. Flavors disinfection decoction.

2. Shushi heat Melancholia: seen in summer and autumn, the affected area, such as agglomeration cone, single or multiple, burning pain, chest tightness, anorexia, deficient urination, red tongue, greasy or yellowish, veins slippery. Qingshu dampness, detoxification swelling. Qingshu Decoction.

3. Is virtual evil love cards: distributed in the body, local color dark red, pus scarce, one after another, delayed healing, with fever, irritability, thirst, or fatigue, limb soft, red tongue thin yellow, rapid pulse. Righting detoxification. Liu Wei Di Huang Decoction.

Second, external treatment and other treatment:

1. The beginning of detoxification should be swelling, moderate to henbane, water reconcile, wrap the affected area. Or wishful golden powder for external application. Or green cream Waicha.

2. Pus, the clip bolt out the pus.

3. Unhealed after the collapse, sores can be a little ninety-one Dan to drugs or drug line twist into sores, topical berberine gauze.

4. Oral Meihuadianshe Dan, Niuhuangjiedu, Fang Feng Tong Sheng Wan, Liushen other medicine.

5. Unilateral prescription: Silver Flower 30g, licorice 10g, decoction, on behalf of the tea.

Western boil treatment

1. Local treatment, such as heat, physical therapy, 10% ichthyol coated ointment. Facial Boil should rest in bed should not squeeze or prick Boil, so as not to spread to the brain.

2. Swelling or have a large range of obvious symptoms, should give systemic antibiotics (third-generation cephalosporin antibiotics).

3. The formation of abscess, incision and drainage should be timely but should be avoided Boil the face cut.

(a) treatment

1. The principles of early treatment to promote inflammation subsided, after early drain purulent pus; timely elimination of systemic adverse reactions.

2. Local treatment

(1) Physical therapy: early, ultraviolet micro-irradiation, can promote local anti-inflammatory, to prevent proliferation. Swelling stage, the selection of FM, infrared and other heat, promote Boil liquid. 2 to 3 times / d, 20 ~ 30min / times.

(2) Drug eraser: 0.5% povidone-iodine scrub, the drug not only for skin irritation, and the role of long-lasting, no pigmentation. Can also be used erythromycin, tetracycline ointment.

(3) topical cream: local swelling and a small pustules, use ichthyol, wishful golden powder, Gyokuro powder and so on.

(4) incision and drainage: Boil into pus, nodules soften, a sense of volatility, you can make a small incision drainage or fire needle drainage. Taboo squeeze purulent lesions.

(5) to keep local clean and dry: adhere to local skin cleaning, daily showers are the best conditions. Young children with skin, topical lip after taking a bath in summer, to avoid the formation of multiple Boil.

3. Systemic treatment usually does not require systemic treatment of boils. But facial boils or accompanied by chills, fever, headache, general malaise, etc., should be given antibiotics. Clinical observations and experimental results show that the efficacy of penicillin, cephalothin, cefazolin and amikacin better effect.

(B) the prognosis

generally good prognosis after active treatment, without sequelae.


boil should be how?

1. Peripheral blood

(1) white blood cell count: fever, elevated WBC count may have.

(2) white blood cell count: white blood cell count was elevated often accompanied by increased neutrophils .

2. diabetes check

(1) fasting plasma glucose measurement: two fasting blood glucose were increased, should consider the possibility of diabetes.

(2) glycated serum protein: This clinical trial is not the impact of fluctuations in blood glucose higher than normal to help the diagnosis of diabetes.

(3) glycosylated hemoglobin: glycosylated hemoglobin and blood glucose were positively correlated, and the irreversible reaction. Diabetes is often higher than the normal 2 to 3 times.

3. bacteriologic

(1) bacterial culture: the multiple, repeated infections, abscesses can be extracted directly pus for bacterial culture, positive results will help the diagnosis of pathogens.

(2) drug susceptibility testing: bacterial culture in the pus, while line drug susceptibility testing can provide the scientific basis of clinical drug treatment.


boil diseases easily confused?

1. Multiple sweat gland abscesses are summer disease, more common in infants and young children and frail mother's head, forehead, etc .. Lesions of multiple subcutaneous abscesses. Surface tenderness, inflammation lighter. No pus bolt, left scars. Usually accompanied by a lot of prickly heat. Generally known as prickly heat poison. It was also known as pseudo furunculosis (Pseudofurunculosis).

2. Hidradenitis suppurativa common in young women, lesions of the skin induration. Subcutaneous abscess formation, followed by skin redness, swelling, heat, pain, ulceration scarring. Lesions occur in the armpits, groin, genital and perianal, umbilical, etc.

3. acne acne mild infection, red, swollen, painful, but the disease is small, the top a little bit like creamy.

4. sebaceous cysts sebaceous cyst infection are redness, swelling, pain, but the previous round has been painless mass over an extended period , the epidermis as usual.

5. carbuncle carbuncle with redness, swelling, pain, but there are several hair follicle infection, lesions larger than the boil.


hump-related diseases
