What is generalized vitiligo?

Generalized vitiligo, as opposed to localized vitiligo, generally covers larger areas and can appear on various parts of the body, while localized vitiligo typically occurs in only one area, such as the palms or around the mouth. Once this disease is discovered, especially generalized vitiligo, it must be treated properly; otherwise, the affected area can increase, making treatment more difficult later on. Treatment should be sought at a reputable hospital's dermatology department, where a combination of oral medication, topical medication, and 308 laser therapy can be effective. During treatment, it's important to exercise to strengthen the immune system, avoid foods rich in vitamin C, and consume more dark-colored foods, which can help in the production of melanin.

What are the treatment methods for vitiligo?

Currently, there are many methods to treat vitiligo, with the most traditional being oral and topical medications, combined with 308 laser treatment. For larger affected areas, fire needle therapy followed by 308 laser treatment can also be used. If the vitiligo is in a stable phase, meaning there has been no change for at least a year, whether treated or not, and no expansion or shrinkage has been observed, this is called the stable phase. In such cases, melanocyte transplantation can be employed. Generally, the more methods are used to treat vitiligo, the better the outcomes. It is advisable to seek treatment in the dermatology department of a reputable hospital using standardized treatments. Avoid using folk remedies or single treatments, as they may delay proper treatment and complicate the condition.

Can vitiligo patches be tattooed?

Vitiligo is related to decreased immunity, genetic heredity, copper deficiency in the body, or local trauma. Therefore, it is advised not to tattoo over vitiligo patches, as tattooing can cause trauma to the skin surface and potentially lead to more severe loss of melanin. People with this condition should avoid getting tattoos. They should seek standard treatment at a regular hospital's dermatology department. Treatment typically involves oral medications, topical medications, and the use of a 308-nm excimer laser, which can accelerate recovery. During treatment, it is important to exercise regularly to boost immunity. It is recommended to eat more black foods and to avoid an excess of vitamin C-rich foods and spicy, stimulating foods. Try to avoid staying up late.

Does vitiligo spread through close contact?

Vitiligo is a type of autoimmune systemic disease. The most common causes of the disease are decreased immunity, genetic heredity, copper deficiency in the body, or local injuries. This disease is not contagious, which means that contact or living together will not transmit it to each other, and this can be reassured. However, treating this disease can be quite troublesome, time-consuming, and slow in showing results. Once diagnosed, it is essential to seek treatment in the dermatology department of a reputable hospital. Treatment options can include oral medication combined with topical drugs and 308 laser treatment, which tends to have quicker effects. During and after the treatment, it is necessary to continue using medication to consolidate the effects, enhance physical exercise, boost immunity, and consume more black-colored foods. Foods rich in vitamin C should not be consumed in excess.

What foods are good for acne?

Acne is associated with vigorous sebaceous gland secretion, consuming spicy, stimulating foods, or frequently staying up late. In daily life, eating spicy, overly greasy, overly sweet, or strongly flavored foods can stimulate excessive secretion of the sebaceous glands. During the secretion process, when mixed with bacteria on the skin surface, acne infection forms. Therefore, it is essential to maintain a light diet, consume more vegetables, fruits, eggs, milk, and lean meat, and avoid overly greasy fried foods, sweets, or overly spicy foods. It's also important to avoid staying up late, feeling anxious or stressed, and to engage in regular exercise, sweat more, and take more showers, as these can all help with the condition.

How to determine if it is chickenpox

Chickenpox is caused by an infection with the varicella-zoster virus and is highly contagious, spreading through contact with one another. Generally, the initial symptoms of chickenpox appear as small blisters on the body, which tend to increase in number within a day or two. Some blisters may burst or erode, particularly on the scalp, and are often accompanied by feverish symptoms. The natural course of the disease is about a week, and mild cases can recover spontaneously within a week. It is recommended that if diagnosed with chickenpox, antiviral medication should be administered and isolation should be practiced to avoid contact with children or older adults with weakened immune systems. Generally, treatment for about a week can lead to recovery.

How to deal with papular urticaria?

Papular urticaria is a type of contact allergic disease, often related to mosquito or flea bites. It manifests as red papules or central red wheals at the site of contact, with either a red puncture mark or blisters. For such conditions, the most common treatment is anti-allergy therapy, such as topical application of calamine lotion and oral antihistamines like loratadine. If the central blister is large, it can be disinfected with iodine, punctured, and the fluid squeezed out. It is advisable to avoid keeping small animals at home, maintain a standardized diet and lifestyle habits, avoid mosquito-infested areas, and ensure that clothing and bedding at home are thoroughly sunned and disinfected.

Can a corn be squeezed out?

Using squeezing as a method to treat corns is not effective, and it will not extrude them. Corns are mostly formed due to foreign bodies entering the skin and repeated friction. After the onset of this condition, walking can be painful and uncomfortable. The most standard and direct method is to use a corn plaster for local application. These corrosive medications can completely clear the corns. If the effect is not very good, one can also go to the dermatology department of a regular hospital to undergo cryotherapy with liquid nitrogen. After cryotherapy, blisters form locally, which gradually heal, causing the corn to necrose and fall off. Therefore, after this disease occurs, it is essential to seek proper treatment and not to use squeezing. This method can cause pain in the corns and may also lead to symptoms of redness and infection.

What should I do about genital herpes?

Genital herpes is caused by herpes simplex virus type 2 infection. Clinically, it is categorized as a sexually transmitted disease and is contracted through sexual contact. Once the disease appears, it cannot be completely eradicated. The virus is carried for life, and may flare up when the immune system is compromised or after consuming spicy and irritating foods. The recurrence interval varies between patients; some may experience a recurrence once a year, while others may experience it monthly. Therefore, after the onset of this disease, it is crucial to seek proper treatment in the dermatology department of a reputable hospital. Antiviral and immune-boosting medications should be taken for an extended period. Additionally, it is important to avoid spicy and irritating foods, exercise regularly to potentially reduce the recurrence of the disease. Furthermore, the disease is highly contagious during an outbreak, and it is essential to avoid sexual contact during this period.

Sebaceous cyst should go to which department?

Sebaceous cysts are characterized by hyperactive sebaceous gland secretion, resulting in benign proliferations under the skin. Generally speaking, this condition falls under the purview of dermatological treatments, but general surgery can also manage it. Common oral and topical anti-inflammatory medications are ineffective for this condition, which contains a sac filled with a tofu-dreg-like substance. The most standard treatment is a minor surgical procedure to completely remove these contents. There is also a possibility of recurrence with this disease. After complete recovery, it is crucial to maintain a healthy diet and lifestyle, avoiding spicy and irritating foods, not staying up late, exercising more, bathing frequently, sweating more, and avoiding public baths and swimming pools where possible.
