foreskin capitis
Introduction
Introduction to foreskin penile head inflammation The phimosis and foreskin are too long to accumulate under the foreskin. The white bean curd-like smeg-like scale formed by sebaceous gland secretions and exfoliated epidermis, occasionally formed into stones, and prone to bacterial infection, forming foreskin penis inflammation, recurrent episodes of foreskin penis inflammation Stimulation is closely related to the occurrence of penile cancer. The disease can also be caused by bacterial, fungal infections or drug allergies. basic knowledge Sickness ratio: 0.05% Susceptible people: good for adult males Mode of infection: non-infectious Complications: balanitis urethritis condyloma acuminata
Cause
The cause of foreskin penile inflammation
The main cause of penile head dermatitis is that the phimosis or foreskin is too long. In addition, unclean sexual intercourse, drug stimulation or allergy is also the cause of the disease.
The pathogens are Streptococcus, Staphylococcus, Escherichia coli and Candida albicans, sometimes caused by Trichomonas vaginalis, Candida penile headitis is caused by Candida infection, and more due to the spouse of Candida Infected with vaginitis, it can also be secondary to diabetes, old and frail and after the application of corticosteroids, immunosuppressive drugs and antibiotics.
External stimulus (30%):
In addition to physiological phimosis, the foreskin is too long, after the sexual maturity of smegma stimulation or a few mechanical damage factors, the glans redness and swelling, burning inflammation changes.
Bacterial infection (20%):
Infectious or communicable diseases, unless the infection factor caused by foreskin balanitis, that is, the pathogenic microorganisms are the leading factors caused by foreskin balanitis, of which bacterial and fungal infections are the most common. Infectious male foreskin balanitis pathogens except for a few toxin-prone bacteria (such as gonococcus), most of them are non-pathogenic microorganisms or low-toxic bacteria often in the case of conditions, can become a causative factor, it is also called conditions Disease caused by germs.
Allergies (20%):
Allergies can also cause the disease.
Prevention
Foreskin penis inflammation prevention
Should promote the health knowledge, phimosis and foreskin is too long and repeated inflammation, often cause foreskin adhesion, urethral stricture, causing dysuria, a more serious problem is that recurrent inflammation is often the main cause of penile cancer.
Precaution
1. Early circumcision of phimosis is the main measure to prevent foreskin penis inflammation.
2. Keep the genitals clean and avoid unclean sexual intercourse and do not take allergic drugs.
Complication
Complications of foreskin penile inflammation Complications balanitis urethritis condyloma acuminata
Male phimosis, too long foreskin has an impact on men's health:
1, hinder development: phimosis, penis and glans development is often restricted, from the appearance of a small penis.
2, easy to get urinary infectious diseases, due to the role of sediments such as urinary scale in the foreskin, can cause dermatitis, balanitis, urethritis, genital warts, gonorrhea and other diseases.
Symptom
Foreskin penis head symptoms common symptoms purulent secretions foreskin is too long skin itching urethra itching heat pain penis itching repeated infection urethra itching foreskin white penis erection is not hard
1. The foreskin is too long or the history of phimosis.
2. The foreskin glans are red and swollen and hot, and the urination is aggravated.
3. There is a purulent discharge from the foreskin.
4. Repeated infection caused the foreskin glans to adhere and even the urethral stricture, dysuria.
Examine
Examination of foreskin penile head inflammation
1. Checking the test: Candida balanitis (the dermatitis) can be found in the glans and foreskin of the lesion, or can be found in Candida. Trichomonas balanitis can find trichomoniasis on secretions.
2. Direct microscopic examination: scrape the surface scales of the glans, coronal sulcus or foreskin at the penis as the specimen to be examined. The specimens to be inspected were made with 10% potassium hydroxide or physiological saline, and clusters of egg-shaped spores and pseudohyphae were observed under the microscope. If more pseudohyphae were found, it indicated that Candida was in the pathogenic stage.
3. Staining examination: Gram staining, Congo red staining or PAS staining can be used for microscopic examination. The positive rate is higher than that of direct microscopy. Gram staining, spores and pseudohyphae dyed in blue: Congo red and PAS staining, spores and pseudohyphae dyed red.
4. Isolation and culture: Candida culture can be performed in patients with negative smear test. The test specimens were inoculated on Sabouraud medium under aseptic conditions. When inoculation, the test tube culture medium was cut obliquely, and each tube was inoculated with 2-3 spots, and each sample was inoculated with 2 tubes. The medium was incubated in a 37 ° C incubator for 24-48 hours, and a large number of milky white colonies were observed. A small number of colony smears were picked with the inoculation needle, and microscopic examination or microscopic examination was performed. A large number of spores were observed. Diagnosed as a Candida infection.
5. Candida antibody test: Candida albicans antibodies can be detected by immunodiffusion or latex coagulation.
Diagnosis
Diagnosis and differentiation of foreskin penile head inflammation
Differential diagnosis
1. Penis syphilis
Most often occurs in the head of the penis and the foreskin, often with ulcers and exudates, but there is a history of unclean sexual intercourse. The small red spots that are initially congested develop into a typical ulcer within a week. The ulcer surface is superficial, the surface is flat, and the edges are high. The hair is hard, the serum is exuded at the bottom, and the dark vision test reveals the Treponema pallidum.
2. Soft squat
The penis head and foreskin mucosa are moist, red, swollen, have secretions, and have a history of sexually transmitted diseases. The course of the disease is milder, the secretions are less, the odor is lighter, the inguinal lymph nodes are swollen, often forming edema, and the secretion is directly smeared. Or culture can be checked for D. faecalis.
3. gonorrhea
Has urethral redness, itching, pain, thin mucus or deep yellow pus, bilateral inguinal lymph nodes swelling, but there is a history of exposure, urethral pus smear staining can be found in multinucleated white blood cells have Gram-negative double Cocci are present.
4. Specific ring-like penile head inflammation
At the initial onset, the penis head and the foreskin mucosa have tiny erosions, and there are a lot of yellow-white odorous exudate, followed by ulceration. In severe cases, necrosis can occur, but the history of saliva staining with penis, secretion smear or bacterial culture Spirochetes and Clostridium can be found.
5. Occlusive dry penile head inflammation
The lesion is also in the foreskin and urethral opening, but the disease is relatively rare, mainly characterized by chronic progressive sclerosing lesions, white dry and shiny epidermal atrophy around the foreskin and urethral opening, fibrosis, penile atrophy Wrinkled, there is a parchment-like mucous membrane covering the penis head.
6. Penile herpes
There are multiple blisters and ulcers on the back of the penis, the foreskin and the back of the penis, but it is caused by a special herpes virus infection. It is kept clean and can heal itself within a few days. The virus can be isolated from the surface secretion of the ulcer.
7. Penile cancer
Because the occurrence of penile cancer is closely related to the long length of the phimosis and foreskin, and most often occurs in the penis head, the inner skin of the foreskin and the coronal sulcus, the initial stage is papules, ulcers, sputum or cauliflower-like tumors, followed by erosion and hard edges. Not neat, there are secretions: 'bleeding and stench, tissue biopsy can find cancer cells.
8. Penile tuberculosis
Chronic ulcers of the penis head of penile tuberculosis are often mixed as non-specific infections, but the ulcers have a long course of disease and long-term cure. The edges of the ulcers are clearly excavated, surrounded by infiltrative induration, basal granulation tissue or necrotic tissue, secretions Mycobacterium tuberculosis can be detected by smear or culture.
