Baby acne

Introduction to baby acne Infantileacne, also known as neonatal acne (Acneneonatorum), the cause of the disease is unclear, may be caused by increased androgen secretion at birth, there is a family tendency to occur within 3 months, almost all boys. Acne can resolve within a few months, leaving a scar after the healing. basic knowledge The proportion of illness: 1% - 3% (the disease is rare in children, generally 1% - 3% or so.) Susceptible people: children Mode of infection: non-infectious Complications: skin cysts

Baby acne cause

(1) Causes of the disease

The cause of the disease is unclear, and there is often a family history. The same patient in the family may be related to heredity and is prone to severe acne during puberty.

(two) pathogenesis

At birth, androgen secretion increases, sebaceous glands develop well, stimulating hair follicles, and individual children may be associated with precocious puberty or masculinization syndrome, which may be related to endocrine function.

Baby acne prevention

The cause of the disease and the child's fetal fat after delivery are not cleaned, and there is hypoxia caused by meconium contamination in the mother body, and the seizure is induced by the meridian repeatedly irritating the skin. Therefore, clinical prevention should be carried out according to the cause. After the birth, attention should be paid to keeping the skin mucous membrane clean, which can reduce the incidence of the disease. The skin can be cleaned by the baby shower gel to completely remove the fetal fat attached to the mucous membrane of the skin. The occurrence of the disease.

Baby acne complications Complications skin cysts

The disease can cause complications such as powdery tumors, whiteheads, acne, cysts, scars, nodules.

Baby acne symptoms Common symptoms Eyebrow sag baby blackhead acne baby scalp with yellow knots blackheads acne papules nodules cyst pustules

Rarely, those who occur within 3 months, almost all male infants, occur in 3 months to 2 years old, slightly more than male infants, skin lesions begin with scattered blackheads, and a small number of pimples and pustules can occur. Occasionally nodules or cysts, mostly in the cheeks, can also affect the forehead and ankle, acne can resolve within a few weeks, pimples and pustules can be cured within 6 months, after the recess can be left. A few can survive more than 1 year and are prone to morbidity.

Baby acne examination

1. Acetic acid white test. The carcass is externally coated with 3-5% acetic acid for 2-5 minutes, and the lesion becomes white and slightly elevated, and the anal lesion may take 15 minutes. The principle of this test is the result of whitening of proteins and acids. The keratin produced by HPV-infected cells is different from that of normal uninfected epithelial cells, and only the former can be decolorized by acetic acid. The sensitivity of the acetic acid white test for detecting HPV is very high, and it is better than the conventional detection of histological changes;

2. Immunohistological examination. The peroxidase antiperoxidase method (PAP) is commonly used to display viral proteins in the sputum to prove that there is a viral antigen in the sputum lesion. When HPV protein is positive, a weak red-positive reaction may occur in superficial epithelial cells of acne;

3. Histochemical examination. A small amount of diseased tissue was taken to make a smear, and stained with an antibody specific for human papillomavirus. If there is a viral antigen in the lesion, the antigen and antibody bind. In the peroxidase antiperoxidase (PAP) method, the core can be stained red. This method is specific and rapid, and is helpful for diagnosis;

4. Pathological examination. Mainly for parakeratosis, high abdomen hypertrophy, papillary hyperplasia, epidermal thickening, prolongation, its degree of hyperplasia may be pseudo-epitheliomatosis. The thorn cells and basal cells have a considerable number of nuclear divisions, which are quite cancerous;

5. Genetic diagnosis. To date, HPV has been difficult to detect using traditional viral culture and serological techniques. The main experimental diagnostic technique is nucleic acid hybridization. The PCR method developed in recent years has the advantages of being specific, sensitive, simple and rapid, and opens up a new way for HPV detection.

Diagnosis and diagnosis of baby acne

diagnosis

According to clinical manifestations, examination can be diagnosed.

Differential diagnosis

The disease should be differentiated from milk thistle.
