Is folliculitis contagious?
Folliculitis is an inflammation of the skin surface caused by self-inflammation infection, primarily related to Staphylococcus aureus, and some are caused by Keratinophyton infections. Generally, this disease is not contagious and will not spread through contact with others. However, some cases of the disease can progressively develop into more severe forms, forming large abscesses or cysts. Therefore, once folliculitis occurs, it is essential to undergo proper treatment, which can include oral and topical anti-inflammatory medications. If the folliculitis is relatively minor, it can also be treated by disinfecting with iodine followed by lancing to clean out the pus and blood. It is important to consistently avoid spicy and irritating foods, refrain from staying up late, and avoid public baths and swimming pools.
Is papular urticaria chickenpox?
Chickenpox is caused by an infection with the varicella-zoster virus and is contagious. It is common among children, though some adults may also contract chickenpox. Once it appears, it is highly contagious and needs to be treated with antiviral medication. Papular urticaria is caused by allergies, often related to mosquito or flea bites. Standard antiallergic medication is typically sufficient for treatment. Occasionally, papular urticaria can present with small blisters similar to those seen in chickenpox, but they are different diseases. If it is difficult to distinguish between them, it is advisable to visit a dermatologist at a formal hospital for diagnosis and treatment.
Can alopecia areata dye hair?
There are many causes for alopecia areata, most of which are related to diet and lifestyle habits. For example, frequently being picky about food, having an unbalanced diet, or consuming spicy and heavily flavored foods can trigger it. Long-term staying up late, anxiety, stress, and being in a bad mood can also cause it. Once alopecia areata occurs, try to avoid dyeing or perming your hair, as these chemical materials can potentially irritate the scalp and exacerbate the condition. It is recommended to seek proper treatment immediately after discovery, otherwise the condition might worsen, leading to complete hair loss or loss of eyebrows. Regular consumption of beans and maintaining a healthy diet and sleep schedule are also advised.
Can tinea pedis be cured?
Athlete's foot is a disease caused by fungal infection. Fungal infections are highly contagious and recurrent, but they can be completely cured with proper treatment. It is recommended to visit the dermatology department of a regular hospital and apply antifungal cream. The treatment should be prolonged, lasting at least one to two months or more, so that the deep-seated fungus can be completely killed and eradicated. After the treatment, regulate your diet and lifestyle habits; avoid contact with small animals, dirty water, sand, etc., try to avoid spicy and irritating foods, and do not stay up late. If family members also have this disease, they must be treated at the same time, and towels, bath scrubbers, or foot wiping towels should not be shared.
The difference between hyperhidrosis and bromhidrosis
Hyperhidrosis is generally a disease caused by one's own endocrine imbalance or hormonal levels. The most characteristic symptom of this disease is increased sweating, such as excessive sweating from the armpits, groin, or palms, especially after exercise or staying up late, but there is no abnormal odor. Bromhidrosis is a type of hereditary disease, characterized by excessive sweating from both armpits and a strong odor, which can start showing symptoms from puberty. Bromhidrosis cannot be completely eradicated, while hyperhidrosis can be cured through proper medical treatment. The most common treatment for bromhidrosis is surgical removal of the large sweat glands, which can reduce or alleviate the odor, but cannot eradicate it completely.
Can syringoma be removed by laser?
Currently, the most common method for treating syringoma is using laser for direct removal. Syringoma is generally related to familial inheritance or local abnormal development of sweat ducts. Often eating spicy and stimulating foods, or using poor-quality eye creams or cosmetics can also lead to the occurrence of syringomas. The most common treatment still involves direct removal with a laser, followed by the application of medications to repair the wound. This helps prevent the condition from recurring. However, there is currently no way to completely eradicate syringomas to achieve a one-time, non-recurrent treatment. After treatment, it is advisable to exercise more and sweat more to increase the secretion of sweat. Avoid using poor-quality cosmetics topically to prevent clogging and recurrence of the condition, and strengthen your exercise regime to enhance immunity.
Is artificial urticaria contagious?
Artificial urticaria is a disease caused by allergies, and it is one of the more difficult types of urticaria to treat. This disease is not contagious and will not spread through contact with others. Once diagnosed with this disease, formal treatment is necessary, and one can visit the dermatology department of a standard hospital for oral antiallergic medication treatment. If the condition persists for a long time and the treatment effects are unsatisfactory, it might be helpful to check for allergens to ascertain what triggers the allergy. Common allergens often include diet, living environment, dust mites, or pollen. Therefore, during and after treatment, it is advisable to enhance physical exercise to boost immunity, avoid keeping pets, stay away from places with dense vegetation, and refrain from consuming spicy and stimulating foods.
What is the white substance in acne?
The white substance in acne is mostly formed by the normal secretions of sebaceous glands accumulating at the mouth of hair follicles, combined with the fermentation of Propionibacterium acnes or Staphylococcus aureus, resulting in pus. Some of the white substances appear as tofu-dregs-like, which are pus formed after vigorous secretion of the sebaceous glands and then absorbed and dried. These substances can be treated with oral and topical anti-inflammatory medications. During treatment, it is also important to regulate one's diet and lifestyle habits, avoiding spicy and stimulating foods to reduce sebum secretion. It is also helpful to avoid staying up late, anxiety, and stress to alleviate symptoms or prevent recurrence.
Can filiform warts be transmitted between spouses?
Filiform warts are caused by human papillomavirus (HPV) infection, which is quite contagious. Transmission between spouses can be more severe due to prolonged contact, or sharing items like towels and bath mitts, which can lead to infection. Once one person is infected, it is crucial to seek standardized treatment at a hospital. The most common treatment currently used is laser removal, which in most cases can cure the condition in one or two sessions. However, some patients may experience recurrent outbreaks, requiring laser treatment each time to prevent the warts from multiplying and spreading. During treatment, towels and bath mitts should be frequently disinfected and not shared. Additionally, it is recommended to engage in regular exercise to boost the immune system, or take oral medications that enhance immunity to prevent recurrence.
How to treat sebaceous cysts?
Sebaceous cysts are benign proliferations that form under the skin in areas where the sebaceous glands are particularly active. They contain a sac filled with a substance that resembles tofu dregs. The most common treatment is a minor surgery to completely remove the contents of the cyst. After recovery, it is important to maintain a proper diet and lifestyle, avoid spicy and irritating foods, refrain from drinking alcohol and eating hot peppers, try not to stay up late, and avoid soaking in public baths or swimming pools. This condition has a tendency to recur, but forming good life habits after recovery can greatly reduce the recurrence rate. Additionally, oral medications that reduce sebum secretion may be taken, and frequent bathing with sulfur soap can help reduce bacterial infections on the skin surface. (Specific medications should be taken under the guidance of a physician.)
