Difference between Tinea Capitis and Psoriasis
Tinea capitis and psoriasis are quite different from each other, starting with their causes. The causes of psoriasis are not very clear and may be related to factors like immune infection and heredity, whereas the cause of tinea capitis is quite clear, as it is caused by fungal infection. Furthermore, their treatments differ. It is recommended to use antifungal medications to treat tinea capitis, while psoriasis is generally treated with immunosuppressants and corticosteroids. Finally, the symptoms of tinea capitis include scaly patches, crusting, and itching, whereas psoriasis typically presents with scaly erythema, pustules, and less itching.
What medicine is good for erysipelas when taken orally?
Erysipelas is a bacterial skin disease involving the deeper layers of the skin, caused by Group A streptococcal infection. The bacteria can enter the body through minor wounds in the skin or mucous membranes, and the disease develops when the body's immune resistance is low. Erysipelas has a rapid onset, and its typical symptoms include edematous erythema with clear boundaries, a tense and shiny surface, and rapid expansion to the surrounding areas. There may also be swollen lymph nodes and varying degrees of systemic symptoms, with the condition typically peaking within four to five days. The primary treatment for erysipelas involves anti-inflammatory medications, namely antibiotics. Penicillin is commonly used; if there is an allergy to penicillin, alternatives like erythromycin, azithromycin, roxithromycin, levofloxacin, or ciprofloxacin can be used. Early, adequate, and effective antibiotic treatment can alleviate systemic symptoms, control the spread of inflammation, and prevent recurrence.
Can tinea unguium be transmitted to others?
Nail fungus is contagious to others. Also known as onychomycosis or gray nails, it is caused by a fungal infection. The fungus can spread from person to person through the skin, both by direct and indirect contact, so it's crucial to completely cure nail fungus promptly, maintain good personal hygiene, avoid wearing tight shoes and socks, avoid sharing footwear, and keep the skin dry.
How to prevent frostbite
Frostbite is a skin disease caused by local skin inflammation due to cold weather. Therefore, it is crucial to prevent frostbite by avoiding prolonged exposure to cold, low-temperature environments. If it is necessary to be in such environments, it is essential to keep both the local areas and the entire body warm. You can wear hats, earmuffs, and gloves, and put on thicker shoes and socks. However, shoes, socks, and gloves should not be too tight, as overly tight clothing can also lead to frostbite.
What does prickly heat look like?
Prickly heat is one of the most common acute skin inflammations in summer, caused by blocked sweat pores. It often occurs on the scalp, forehead, neck, chest, armpits, and groin. The skin becomes red, followed by the appearance of small, red papules or vesicular rashes, densely clustered. Some of these papules can develop into pustules. After developing prickly heat, intense itching or pain can occur. Therefore, in summer, it is important to keep indoor ventilation and cooling, and children's clothing should be loose, soft, and highly absorbent.
Early symptoms of syphilis
Syphilis is a sexually transmitted disease caused by the bacterium Treponema pallidum, with the disease course within two years referred to as early syphilis. Not all infected individuals display symptoms; asymptomatic syphilis is also known as latent syphilis. Symptomatic early syphilis primarily manifests as either primary or secondary syphilis. The main symptom of primary syphilis is a chancre, typically occurring as a clear-bordered ulcer in the genital area. It is flesh-colored and neither painful nor itchy. Several weeks after the chancre heals, secondary syphilis can develop, characterized by a rash that may resemble other skin conditions. Common manifestations include macules, papular macules, copper-red papules on hands and feet, flat condyloma, and syphilitic alopecia. Individuals who suspect they may have been exposed to syphilis should visit a hospital for a blood test to detect syphilis antibodies. Antibodies can usually be detected four weeks after infection, and a negative result three months later can rule out syphilis.
Are tinea unguium and onychomycosis the same?
Tinea unguium and onychomycosis are the same, these two are exactly the same disease, with no differences, only that their names are different. Tinea unguium is more commonly used in clinical diagnosis, while onychomycosis is a common term used by the public. If you have tinea unguium, also known as onychomycosis, it is crucial to actively seek treatment to completely cure it, because this disease is contagious. If not treated promptly, it can easily spread from person to person. Always pay attention to hygiene and cleanliness.
Can you have sexual intercourse with herpes zoster?
Firstly, it is advised not to have sexual intercourse during an episode of shingles to avoid cross-infection and aid recovery. Humans are the only hosts for the varicella-zoster virus, which can enter the body through respiratory and oral tracts, genital mucosa, saliva, and skin, and lies dormant in human mucosa, blood, saliva, spinal cord, posterior nerve roots, and sensory ganglia cells. People with acute shingles need to seek prompt medical diagnosis to avoid missing the optimal treatment window and delaying the condition. The treatment principles mainly include antiviral therapy, infection control, pain relief, and aiding scab formation. Typically, proper recovery from shingles is expected within seven to ten days in a standard hospital, and this helps in reducing the occurrence of postherpetic neuralgia.
Which fruits should not be eaten with syringoma?
Patients with syringoma should pay attention to their diet. First, they should not eat fruits that can easily cause allergies, such as mangoes, lychees, and almonds. Secondly, avoid eating irritating foods, such as chili peppers, pepper, scallions, garlic, and ginger. Moreover, avoid consuming greasy foods, like lard and fatty meats. Finally, do not drink alcohol, do not eat seafood, and avoid foods that can trigger and exacerbate this condition.
The difference between acne and folliculitis
Acne and folliculitis, although both are skin diseases, have significant differences. Firstly, acne is caused by bacteria such as Propionibacterium acnes, while folliculitis is mainly caused by Staphylococcus aureus infection. Secondly, their treatments differ. Finally, the symptoms of acne and folliculitis are also different. Generally, folliculitis does not occur frequently, whereas acne does. Folliculitis initially presents as red papules that progress to pustules. Acne, on the other hand, displays various forms including papules, pustules, as well as blackheads and whiteheads.
