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.
What is the best medicine for erysipelas?
Erysipelas is an infectious disease that commonly affects the lower legs and face. Once erysipelas is diagnosed, penicillin is the recommended treatment. However, if there is an allergy to penicillin, cephalosporins or quinolones can be used as alternatives. Generally, intravenous infusion is necessary; oral administration alone is not effective. Intravenous medication is required to achieve the best anti-inflammatory treatment results.
When is the third stage of syphilis?
Tertiary syphilis is a relatively late stage of syphilis, often occurring two to three years after the initial detection of the disease. For patients with a longer course of the disease, it generally appears five to ten years later. Once tertiary syphilis is diagnosed, it is often accompanied by damage to various organ functions, such as the cardiovascular system, bones, skin, and nervous system. Therefore, it is crucial to detect and treat syphilis early and to follow standard treatment protocols with a doctor. Otherwise, once it progresses to tertiary syphilis, it becomes very difficult to cure.
The difference between roseola and pityriasis rosea
Pityriasis rosea and pityriasis versicolor are completely different conditions. Pityriasis rosea is a disease caused by a herpes virus infection, which is contagious. On the other hand, pityriasis versicolor is an inflammatory skin disease, which is not contagious. The cause is not particularly clear, but it may be related to infections or allergies. Furthermore, the treatments for pityriasis rosea and pityriasis versicolor are different. Pityriasis rosea can be treated with antiviral medications, along with symptomatic treatments such as reducing fever, etc. Pityriasis versicolor is recommended to be treated with antiallergic or astringent medications.
Is tinea capitis easily contagious to adults?
Tinea capitis is not very contagious to adults. Because most adults have stronger resistance to fungi, the likelihood of infection is much smaller than in children. This disease is more common in children or people with poorer skin resistance. Tinea capitis includes yellow tinea, white tinea, black tinea, and dragon tinea. Regardless of the type, active antifungal treatment should be received. Avoid eating irritating foods, such as raw ginger, raw onions, pepper, chili, etc.
