Is there a difference between white patches and vitiligo?
White patches and vitiligo have clear distinctions. White patches primarily refer to localized hypopigmentation on the skin, a type of macule where pigment loss occurs due to a reduction in function or number of melanocytes. White patches can appear on the skin due to various reasons or diseases, including post-inflammatory hypopigmentation, tinea versicolor, and pityriasis alba. Vitiligo, on the other hand, usually refers to a specific skin condition. The causes of vitiligo are multiple and can be related to psychological factors, autoimmune dysfunction, leading to the destruction and reduction in melanocytes. The appearance of white patches in localized skin areas is called vitiligo, and its typical lesion is also a localized white patch, which is a type of white patch. Therefore, diseases causing white patches could potentially include vitiligo or other conditions. Vitiligo is just one possible cause of white patches.
What should I do if alopecia areata has expanded?
When there is an expansion of alopecia areata, local injections of corticosteroids can be used. The treatment with corticosteroids is a kind of occlusive therapy, primarily involving injecting corticosteroids into the area of hair loss. This can suppress inflammation and immune responses around the hair follicles, enabling hair growth and potentially preventing the expansion of alopecia areata. However, some individuals may experience localized skin atrophy after corticosteroid injections, and some may experience depigmentation. Therefore, when alopecia areata is expanding, it is advisable to seek timely treatment at a dermatology department in a reputable hospital. Under the guidance of a doctor, treatment can include topical application of minoxidil solution, or the use of compound preparations like compound styradan tonic for hair growth, as well as oral medications such as cysteine tablets, compound glycyrrhizin capsules, and treatment based on Traditional Chinese Medicine diagnosis and differentiation.
How to cure eczema?
To effectively treat chronic eczema, it is essential first to identify specific triggers and avoid contact to prevent recurrence. Under the guidance of a doctor, oral antihistamines can be administered, commonly options include chlorpheniramine maleate, cetirizine, loratadine, ebastine, and epinastine. In severe cases, infusion therapy might be an option, utilizing calcium gluconate injection or procaine vein blockage. For topical medications, one might choose corticosteroid creams such as desonide ointment or hydrocortisone butyrate cream, or opt for non-steroidal options like Mentholatum Dermacare Cream or Moisture-Removing Anti-Itch Cream. When eczema occurs, it can also be beneficial to combine traditional Chinese medicine and differential diagnosis with Western medicine for better results. Additionally, a light and bland diet is recommended.
How to remove granulation tissue from paronychia
For polyps caused by paronychia that repeatedly flare up and are quite obvious, surgical methods are necessary for complete correction. Surgical options include nail groove plasty and lateral nail fold incision, both of which are effective treatments for severe paronychia. If the polyp from paronychia is not severe, it can be treated with topical medications to shrink the polyp and reduce swelling. Commonly used medications include skin and mucous membrane disinfectants such as povidone-iodine, and continuous damp dressing with medical alcohol can be applied to further reduce swelling, which is beneficial for muscle atrophy. Highly concentrated saline solution or phenol can also be used for local scalding through continuous damp dressing. The growth of a polyp in paronychia indicates repeated inflammatory irritation, which leads to local proliferation, so it is essential to address paronychia promptly when it occurs.
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.
