Is tinea unguium contagious?
Onychomycosis, commonly known as nail fungus, is a nail damage caused by fungal infections of the nail bed. This disease is highly contagious and recurrent; it can be transmitted through contact, such as sharing slippers, foot towels, or socks. The most commonly used treatment is oral antifungal medication. However, if liver function is abnormal and transaminase levels are high, it is advisable not to use oral medications. Topical medications can also be effective, but they require a longer time to work. Otherwise, it is difficult to completely cure the condition in the long term. After recovery, avoid sharing slippers, avoid public baths and swimming pools, and minimize contact with others to prevent cross-infection.
What should I do if the paronychia is draining pus at home?
Paronychia is mostly caused by nail ingrowth into the flesh or local trauma, and can be treated at home with topical povidone-iodine disinfection and mupirocin ointment application if pus appears. Additionally, oral cephalosporin antibiotics can be taken to help healing gradually. However, paronychia tends to recur frequently. Once it occurs, it is recommended to visit a dermatology department at a formal hospital to have the nail trimmed or to consider surgical treatment to prevent recurrence. It is also advisable to avoid wearing tight, cramped shoes to prevent trauma or crushing injuries. Once paronychia develops, the amount of local pus can vary; generally, quicker recovery can be expected once the pus is cleared. (Use medications under the guidance of a doctor.)
Genital warts are caused by how?
Genital warts belong to a type of infection caused by the human papillomavirus (HPV), commonly transmitted through direct sexual contact. Some people are infected in public baths, swimming pools, hotels, or toilets, and can be exposed to contaminated objects. Once diagnosed, formal treatment is necessary. The warts can be removed with laser treatment, combined with antiviral drugs or medications that boost the immune system. During treatment, sexual contact should be avoided to prevent cross-infection. Strengthening exercise, enhancing immunity, avoiding spicy and irritating foods, and abstaining from alcohol are recommended. With proper treatment, the disease can be completely cured. Underwear should be thoroughly sun-dried and disinfected.
Does psoriasis spread?
Psoriasis, commonly known as psoriasis, is a non-contagious disease, but there is a certain probability of genetic inheritance. The main causes of psoriasis are related to reduced immunity, family genetic allergies, or repeated inflammation of the tonsils. The causes are quite complex, and once the disease occurs, it cannot be completely eradicated and may be carried for life with long-term recurrent attacks. After the onset of this disease, it is essential to seek standard treatment at the dermatology department of a formal hospital. Generally, through oral and topical medications, combined with narrow-band ultraviolet phototherapy, clinical cure can generally be achieved. If the symptoms are severe, treatment with biologics can be combined. Normally, it is important to regulate one's diet and lifestyle habits, avoid spicy and stimulating foods, try not to eat raw and cold items, and prevent tonsillitis.
Does papular urticaria spread?
Papular urticaria is a type of allergic disease, mostly related to exposure to irritants, or bites from mosquitoes and fleas. This disease is not contagious, and it cannot be transmitted through contact with others. Once the disease is discovered, it must be treated with proper anti-allergy medications. Additionally, it's important to frequently sun-dry and disinfect personal items such as bed sheets, duvet covers, and clothes. Avoid keeping small animals at home and try to stay away from areas with lots of plants and trees. Some cases of papular urticaria may develop small blisters. These blisters should not be punctured as breaking them can lead to infections and potentially more severe symptoms. Generally, with proper treatment, the symptoms can gradually subside, usually within about a week.
Can people with papular urticaria eat fish?
Papular urticaria is a type of allergic reaction, related to direct contact with irritants or bites from mosquitoes and fleas. During treatment for this condition, it is generally advised to avoid eating spicy foods, fish, and shrimp, as these can aggravate allergic diseases by inducing inflammation or worsening itching. Severe scratching may also lead to the formation of small blisters, which, if burst, could potentially cause bacterial infection. Therefore, this disease must be treated formally. It is advisable to avoid spicy and irritating foods, refrain from staying up late, and avoid places with a high presence of mosquitoes and fleas. Pets should not be kept in the home; if pets are present, it is crucial to maintain their hygiene and regularly disinfect and expose bedding and covers to sunlight.
Can sebaceous cysts grow larger?
Sebaceous cysts are a type of benign hyperplasia, generally formed by the accumulation of sebaceous gland secretions under the skin, and contain a tofu-dregs-like substance within a sac. If left untreated, the disease can gradually grow larger and may cause pain or rupture. Therefore, once discovered, it is best to go to the dermatology department of a regular hospital to have a minor surgery to completely remove the tofu-dregs-like substance and the sac, which will eradicate the disease and prevent recurrence. It is important to maintain good dietary and lifestyle habits, avoid spicy and stimulating foods, avoid staying up late, anxiety, and stress, do not keep small animals in the home, exercise regularly, and bathe frequently.
Can tinea cruris be cured completely?
Jock itch is caused by fungal infections and can be completely cured, as the fungi in this area generally do not penetrate too deeply and mostly adhere to the surface of the skin. Common antifungal creams can effectively treat this disease, but there is a certain likelihood of recurrence. Recurrence is mostly due to re-exposure to fungi and reinfection, such as frequent visits to public baths for soaking and swimming, and mixing washcloths and towels. Some patients have athlete's foot, and mixing socks with underwear during washing can also cause repeated cross-infection. Therefore, during treatment, it is necessary to regulate diet and living habits, and underwear, socks, sheets, and duvet covers must be thoroughly sun-dried and disinfected to avoid visiting public baths and swimming, thereby preventing cross-infection.
Causes and Prevention of Alopecia Areata
Alopecia areata can be caused by a variety of factors and can occur at any age. Generally, alopecia areata in children is mostly related to picky eating or an imbalanced diet, including excessive snacks. Among adolescents or middle-aged individuals, alopecia areata can be related to high stress levels, vigorous sebaceous gland activity, or the frequent consumption of spicy and stimulating foods. For middle-aged and elderly people, it could be related to other diseases within the body, such as liver or kidney disease. Therefore, it is important to foster good dietary and lifestyle habits, strengthen physical exercise to boost immunity, include more legumes in the diet, and regularly massage the scalp, all of which can serve as preventive and therapeutic measures.
What medication should be applied for a sebaceous cyst?
Sebaceous cysts are benign proliferations that form due to the vigorous secretion of sebum by the sebaceous glands. They are generally located subcutaneously, not too deep, and consist of a sac filled with tofu-dreg-like material. This material forms from an initial abscess, whose clear pus gradually dries out. External and oral medications are generally ineffective for this condition, so it is advisable not to use topical medications. The most common treatment approach is to undergo minor surgery at a dermatology department in a reputable hospital to completely remove the sac and its contents. Subsequently, it is important to maintain a healthy diet and lifestyle, avoid spicy and irritating foods, and reduce staying up late to prevent recurrence of the condition.
