What are the symptoms of gonorrhea?
Gonorrhea is mainly a type of infectious skin disease caused by infection with gonococcus. Symptoms of gonorrhea differ between men and women, with men generally presenting more obvious symptoms. Typically, men show early symptoms of gonorrhea about a week after infection with gonococcus, including purulent discharge at the urethral opening, accompanied by symptoms such as frequent urination, urgent urination, and painful urination. In women, gonorrhea usually manifests as cervicitis, with purulent or bloody discharge from the vagina. Many women do not notice early symptoms of gonorrhea, which if ignored can lead to delays in treatment and may result in gonococcal pelvic inflammatory disease. Severe cases can lead to infertility or ectopic pregnancies. If gonorrhea is suspected, it is important to visit a reputable hospital and undergo treatment with antibiotics under the guidance of a doctor.
Is melanoma flat or raised?
Melanoma is generally raised and does not have a fixed shape. In the early stages of local growth, melanoma appears flat. As the tumor grows and proliferates, some protrusions may occur, but protrusions should not be equated with malignancy. If a previously flat mole suddenly becomes raised, one should be vigilant about the possibility of malignancy. However, a raised mole is not necessarily melanoma; there are some intradermal nevi or benign skin lesions, and other types of skin cancers can also manifest as raised changes. Therefore, if there are some melanocytic nevi on the skin that quickly develop symptoms such as ulceration, bleeding, pain, or itching, it is important to promptly visit a dermatology department at a standard hospital for an examination and, if necessary, surgical removal and pathological investigation.
Why do corns keep increasing in number as they grow?
Corns growing in number and size is usually linked to wearing tight shoes and compression. They are also related to localized friction and irritation. Another possibility to consider when corns multiply is an infection caused by human papillomavirus resulting in plantar warts, which are similar in appearance to corns. Plantar warts are somewhat contagious and can also arise when the immune system is weakened. If your corns are increasing in number, it is important to promptly visit a dermatologist at a reputable hospital. Once a clear diagnosis is made, appropriate treatment options may include carbon dioxide laser therapy or cryotherapy using liquid nitrogen. If you are experiencing frequent corns, it is essential to wear loose-fitting shoes with soft soles, minimize walking, and avoid sitting for long periods.
How to treat recurrent neurodermatitis?
Neurodermatitis can recurrently occur and may be treated with anti-allergic medication under the guidance of a doctor. Common choices include loratadine tablets, levocetirizine tablets, desloratadine dispersible tablets, or ebastine capsules. Treatment may also involve Traditional Chinese Medicine (TCM) based on differential diagnosis or opt for proprietary Chinese medicines such as moisturizing and itch-relieving capsules, anti-itch granules, and dermatitis detox pills. If the rash is thickened and lichenified, topical application of compound fluocinonide cream or fluticasone propionate ointment can be used for treatment. Recurrent neurogenic enteritis, often related to staying up late, poor rest, excessive mental tension, and anxiety, necessitates maintaining regular hours and a relaxed mood, and avoiding scratching.
How to remove burn scars
Scars from burns, if relatively fresh, can be treated with scar removal creams such as silicone gel dressings. It is necessary to consistently use these creams for about three months, and using them in conjunction with scar patches can enhance the effects. During the use of scar creams, the diet should also be light, avoiding spicy and irritating foods, and consuming more fresh vegetables and fruits that are rich in Vitamin C, and foods high in vitamins. At the same time, avoid intense exercise and scratching the affected area to prevent worsening of the scar hyperplasia. For older burn scars, fractional laser treatment can be considered. Depending on the degree of scar elevation, typically three to five treatments are needed. (Use medication under the guidance of a doctor)
What is seborrheic dermatitis?
Seborrheic dermatitis refers to a type of inflammatory skin disease that occurs in areas where sebum secretion is abundant, including the face, chest, and back. These areas tend to be oilier and are prone to developing erythema and greasy scales. If the seborrheic dermatitis is of the dry type, it may also be accompanied by symptoms of peeling skin. The condition commonly affects individuals with hyperactive sebaceous glands, typically those with oily skin. Some people have combination skin that is also prone to oiliness, making them susceptible to seborheic dermatitis, often due to improper skin care. Dietary habits, frequent late nights, and consuming overly spicy or greasy foods can also lead to the development of seborrheic dermatitis.
How long will it take for alopecia areata to fully recover once fuzz has started to grow?
Alopecia areata, once showing new fuzz, usually takes three to six months to return to normal. The appearance of fuzz indicates that the alopecia areata is in the recovery phase. In the early recovery stage, lighter-colored fuzz will grow in the area where hair was lost, and this fuzz will gradually turn into normal hair. During the active phase of alopecia areata, there will be noticeable hair loss, while in the dormant phase, the hair loss will stop. Three to four months after the dormant phase, most patients enter the recovery phase, reaching the stage where this small fuzz appears. Hence, the appearance of such fuzz signifies that the alopecia areata is nearing recovery, and new hair will grow during this phase. There are many causes of alopecia areata; it is important to avoid staying up late regularly.
How to deal with a skin scald that has broken the skin?
After a skin burn breaks the skin, if the area is relatively small and there is no obvious swelling, a moisturizing burn ointment can be applied. If the area is larger and accompanied by some exudation and swelling, it is necessary to go to the hospital for timely treatment. Under the guidance of a doctor, antibiotic ointment should be applied, and oral antibiotics should be taken. Common choices include Cefalexin, Cefradine dispersible tablets, and erythromycin for anti-infection treatment. Antibiotics can be used if there is no allergic reaction to them. If severe burn symptoms occur, combined with serious infections, swelling, and significant exudation, it is crucial to go to the hospital for medical treatment immediately. Severe cases may require hospitalization. Do not scratch the skin yourself, and avoid spicy and irritating food.
How can tinea capitis be treated to eradicate it completely?
To achieve a radical cure for tinea capitis, it is first necessary to consider the extent of the condition. If the affected area is not very large, then topical medications may suffice. Common choices for antifungal topical medications include Terbinafine Hydrochloride Cream, Luliconazole Cream, Oxiconazole Nitrate Cream, or Ketoconazole Cream. If the tinea capitis is progressing and there is significant damage to the hair in the affected area, oral medication may be required for treatment. However, liver and kidney function tests should be conducted prior to this. If liver and kidney functions are normal, options include oral Itraconazole Dispersible Tablets, Terbinafine Hydrochloride Tablets, or Fluconazole Capsules. If the local hair condition is severe, it may be necessary to timely shave the head while ensuring cleanliness and hygiene of the scalp during treatment.
Will seborrheic dermatitis recur?
Seborrheic dermatitis is likely to recur. In cases of seborrheic dermatitis, oily skin can easily lead to recurrence. Additionally, an inappropriate diet, often consisting of spicy, irritating food, as well as fried and greasy food, and habitual late nights, can also easily lead to recurrence. Therefore, when seborrheic dermatitis occurs, it’s essential to maintain a light diet, avoiding spicy and irritating foods, and seek treatment under the guidance of a doctor. For topical use, one can choose corticosteroid medications, typically choices include desonide ointment or hydrocortisone butyrate cream. For oral medications, options include Vitamin B6 or a B-complex vitamin. If itching is significant, it might also be necessary to combine treatment with antihistamine medications.
