What causes nail fungus?
Onychomycosis, also known as nail fungus, is an infection caused by pathogenic fungi in the nail plate or under the nail. This disease can infect fingernails as well as toenails. Besides the fundamental cause of pathogenic fungi, other common inducers include the environment, particularly damp environments, and contact with other individuals who have nail fungus, which can be spread to others through direct or indirect contact.
What causes erysipelas?
Erysipelas is an acute inflammation of the skin and reticular lymphatic vessels. The onset of erysipelas is due to hemolytic streptococci invading the skin and mucosal reticular lymphatic vessels through small wounds in the skin mucosa. Erysipelas commonly occurs on the lower limbs and face, progressing rather quickly, with seldom tissue necrosis, and a tendency for recurrent episodes. The local symptoms include patchy erythema, bright red color, lighter in the center, with clear and slightly raised edges.
Post-cryotherapy care for flat warts
Flat warts are a skin condition caused by human papillomavirus infection, and treatment can involve cryotherapy. There are some precautions to take after cryotherapy for flat warts. First, you should avoid getting the area wet for a week after the treatment. Second, it's important to prevent bacterial infections. If redness or pain occurs, apply some anti-inflammatory medication. Lastly, it is advised to follow a light diet, avoid smoking and drinking alcohol, and refrain from consuming spicy and irritating foods.
How to treat tinea capitis?
Tinea capitis, this disease can cause symptoms such as itching, scaling, crusting, and even thick discharge and erosion on the scalp. To treat tinea capitis, it is crucial to maintain cleanliness of the head, and to disinfect daily-used personal items. Furthermore, it is necessary to use topical antifungal medications. For severe cases of tinea capitis, oral medications like ketoconazole or clotrimazole may be required (use of medications should be under the guidance of a doctor).
What family does shingles belong to?
Shingles can be treated in three medical departments. First, dermatology. Since the blisters primarily appear on the skin, seeing a dermatologist can treat shingles. Second, neurology. As shingles may be caused by nerve damage, treatment can be sought from a neurologist. Third, for severe pain, especially if postherpetic neuralgia remains after shingles, one can consult the pain management department. The initial symptoms of shingles are mainly pain, particularly unilateral limb or unilateral scalp/facial pain.
How to distinguish between tinea corporis and psoriasis?
Tinea corporis and psoriasis are both dermatological diseases, but they have significant differences. Firstly, the cause of tinea corporis is clear—it is caused by fungal infections. The cause of psoriasis is not particularly clear, and it is currently believed to be related to multiple factors including immunity, infection, and genetics. Furthermore, tinea typically presents with skin plaques surrounded by a ring of papules, while psoriasis frequently shows as silvery white scales, with bleeding or a film phenomenon. Lastly, their treatment methods are also different.
How to treat acne and pimples
Acne, also known as acne vulgaris, mainly occurs in adolescents. To treat acne, the following suggestions are recommended: First, avoid staying up late, reduce stress, and avoid eating spicy and irritating food. Keep the skin clean and hygienic. Secondly, for mild acne, it is suggested to use some anti-inflammatory and antibacterial antibiotic creams. Lastly, for more severe cases of acne, it is recommended to take some antibiotics or other medications orally. (Please use medication under the guidance of a doctor)
Is rubella the same as urticaria?
Rubella is not urticaria; rubella and urticaria are two completely different diseases. Urticaria is an allergic skin disease, while rubella is a viral infectious disease, which is contagious. Urticaria is not contagious. Rubella can also cause symptoms such as fever and chills, whereas urticaria often causes skin hives and itching. Therefore, rubella is not urticaria.
Will third-stage syphilis be asymptomatic?
In the case of third-stage syphilis, it is generally not asymptomatic, as it is already a late stage of the disease that invades multiple systems, such as the musculoskeletal system, nervous system, and even the cardiovascular system. When these systems are invaded, they become damaged, leading to various complications. Therefore, third-stage syphilis typically presents with various signs of organ dysfunction, and it is unlikely to be without any symptoms once it has progressed to this stage.
What causes tinea capitis?
The fundamental cause of tinea capitis is a fungal infection of the scalp and hair. The fungus mainly consists of various microsporum species, with the rust-red microsporum being the most common. Tinea capitis can be contracted through direct or indirect contact and is common among children and people with weakened immune systems. Symptoms of tinea capitis include dandruff, scabs, itching, and others. It is essential to promptly visit a dermatologist for fungal testing and treatment.
