Symptoms and Treatment of Chickenpox
Chickenpox is primarily caused by an infection with the varicella-zoster virus, and the disease is generally transmitted through the respiratory tract. At the onset of the disease, red papules appear on the body, face, or scalp, which gradually develop into small vesicles. As the vesicles grow, they feel itchy. Scratching them can break the vesicles, leading to oozing and crusting. As the condition progresses, it can peak within two to three days, presenting with widespread vesicles throughout the body. In such cases, antiviral treatment should be promptly administered, such as acyclovir tablets or valacyclovir dispersible tablets. These can be combined with traditional Chinese antiviral medications, such as Scutellaria root oral solution.
What are the early symptoms of vitiligo?
The early symptoms of vitiligo generally appear as a white patch on a localized area of the skin. Initially, the color is not very white, appearing as a vague, hazy white patch. As the condition gradually progresses, the color of the patch becomes whiter and its area expands. If the white patch appears in areas with hair, such as eyebrows, armpits, or the scalp, the hair in these areas will also gradually turn white. Some patients with vitiligo may experience localized itching, but most patients do not experience any discomfort. Once vitiligo is discovered, it is crucial to seek formal treatment at a hospital. Generally, a combination of oral and topical medications, along with 308 laser therapy, yields relatively good results. Treatment can be more challenging if the affected area is large, whereas smaller areas are relatively easier to treat.
What is folliculitis excision surgery?
Most cases of folliculitis are not very severe and can usually be gradually reduced with common oral and topical anti-inflammatory medications. If a particular folliculitis is relatively large, with a pronounced pustule, local disinfection and lancing to remove pus and blood may also be considered. Some cases of folliculitis are characteristically very painful and soft to the touch; in these instances, surgical drainage may be employed. Generally, after thorough surgical cleaning, the area can slowly heal. During treatment, anti-inflammatory medications should continue to be taken orally. It's recommended to avoid spicy and irritating foods for a long period, avoid staying up late, and it is best not to keep small animals at home or go to public baths and swimming pools. (Please use medication under the guidance of a professional physician and do not medicate blindly.)
Precautions for Children with Chickenpox
Chickenpox is caused by the varicella-zoster virus infection, which is more common in children but can also occur in adults. The peak season for this illness is spring. Therefore, after children contract chickenpox, it is crucial to isolate them to prevent contact with other children or the elderly, as it can spread to others quickly. Typically, conventional antiviral medications are sufficient for treatment. If fever occurs, it is advisable to take some fever-reducing medications appropriately. It is also recommended to have a light diet, eat more vegetables and fruits, and drink plenty of water. Adequate rest is important, and if small blisters appear on the body, avoid scratching them to prevent infection and more severe symptoms. Generally, this disease confers lifelong immunity, meaning there is no recurrence after the initial episode.
Is a white patch on the face vitiligo?
White patches on the face are common, with the most typical being pityriasis alba or pityriasis versicolor. These conditions are generally related to a lack of vitamins, trace elements, or fungal infections on the skin's surface. These types of patches are usually vague, with unclear boundaries and may also have some fine scales on them. The second type of white patch is vitiligo, which is usually much whiter. When examined under a Wood's lamp, they appear bright white and have irregular edges, with a tendency for the patches to expand over time. Another type of white patch is the nevus depigmentosus, which is congenital and present from birth. These patches generally do not expand and are not particularly white. If there is any uncertainty, it is best to consult a dermatologist at a reputable hospital and have it confirmed with a Wood’s lamp or a dermatoscope.
How to treat sebaceous cysts
Sebaceous cysts are a type of benign hyperplasia, relating to either the vigorous secretion by one's sebaceous glands or the presence of a localized abscess. The most conventional treatment is to visit the dermatology or general surgery department of a formal hospital to perform a minor surgery, where the cyst sac and tofu-dregs-like material are completely removed for a cure. The underlying causes of this condition are numerous, generally associated with personal diet and lifestyle habits. After recovery, it is crucial to regulate one's diet and lifestyle, persistently avoid spicy and irritating food, prevent staying up late and experiencing anxiety, enhance physical exercise, sweat more, bathe more frequently, which all help in preventing a recurrence. Regularly exposing one's clothing, bed sheets, and quilt covers to sunlight, and avoiding public baths and swimming, also contribute to prevention.
Can folliculitis be popped?
Generally speaking, folliculitis can mostly subside slowly by itself through oral or topical anti-inflammatory medications. If an individual follicle is particularly large, or if long-term medication is ineffective, local disinfection followed by draining the pus can be effective. This condition is associated with vigorous secretion of sebaceous glands, eating spicy and stimulating foods, or frequently staying up late. Therefore, after recovery, it is essential to regulate one's diet and lifestyle habits: avoid staying up late and consuming spicy or heavily flavored foods. Regular exercise, frequent bathing, and sweating can help prevent relapse. Continuously taking medications that reduce sebaceous gland secretion or those that clear heat and purge fire long-term can also be beneficial.
What should I do if my child has chickenpox?
Chickenpox is caused by the varicella-zoster virus infection and is highly contagious, primarily spreading through the air or droplets. Once infected, it quickly spreads to children or older adults who are in contact with each other. It is best for a child with chickenpox to go to a dermatology department at a formal hospital for antiviral medication treatment. Some children may develop a high fever and can take some fever-reducing medicine appropriately; if there is an inflammatory infection, some anti-inflammatory drugs can be taken as needed. During treatment, it is important to isolate, drink plenty of water, and eat a light diet. Try to avoid going outside in the wind or to crowded places to prevent cross-infection. (Doctor's answer is for reference only; medication should be taken under the guidance of a professional physician, do not take medicine blindly.)
Is the appearance of white spots on the back vitiligo?
White patches on the back are not necessarily vitiligo; they could also be tinea versicolor. Tinea versicolor is caused by a fungal infection, generally contagious, and may gradually increase in number after the appearance of one. Additionally, these patches are somewhat blurry in color, not the porcelain white typically seen with vitiligo. If it is vitiligo, the situation is more complicated, and it is necessary to seek formal treatment at a dermatology department of a standard hospital. In the current situation, it is advisable to visit a dermatology department in a formal hospital and use a Wood's lamp or dermatoscope for differential diagnosis to definitively determine if the condition is vitiligo. If it is tinea versicolor, applying antifungal cream alone can completely cure it. If it is vitiligo, a comprehensive treatment is required, involving oral and topical medications, along with 308-nm excimer laser therapy.
Is eczema contagious?
Atopic dermatitis, also known as eczema, is a particular type of eczema that overall falls under allergic diseases. It is related to individual allergic constitution, familial inheritance, and allergies to high-protein substances. This disease usually manifests in childhood and symptoms may decrease as one ages. Atopic dermatitis is not contagious; it cannot be spread through contact, sharing clothes, or living together. However, the treatment cycle for this condition is lengthy and challenging. It is crucial to seek proper treatment in the dermatology department of a reputable hospital. Allergy testing can be conducted followed by desensitization or medication treatment specific to the symptoms identified. After recovery, it is important to enhance physical exercise, strengthen immunity, avoid spicy and irritating foods, and refrain from staying up late.
