What to do if vitiligo spreads during pregnancy?
Generally speaking, during pregnancy, due to reduced immunity, hormonal changes, or deficiencies in vitamins and trace elements, vitiligo can spread and worsen. Using oral and topical medications during this period is troublesome, and pregnant women are generally advised against taking medications. It is advisable to visit the dermatology department of a regular hospital for localized 308 laser treatment, which does not affect pregnant women. It is essential to seek treatment at a reputable medical institution where a doctor can diagnose and provide a treatment plan. During pregnancy, it is recommended to consume more black-colored foods such as black rice, black beans, black sesame, wood ear mushrooms, and mushrooms, while avoiding consuming too much vitamin C-rich food like strawberries, oranges, tomatoes, pineapples, and mangoes.
Can you take a bath with tinea cruris?
Tinea cruris is a disease caused by fungal infections. It is highly contagious and recurrent. It is helpful for the treatment of this disease to bathe frequently in daily life, and to keep the affected area dry and clean. Usually, applying antifungal cream can completely cure it. After it is cured, try to avoid bathing in public baths or swimming, avoid contact with small animals, and if you have athlete's foot, try not to mix socks and underwear when washing to prevent recurrent cross-infection. If the work environment is damp and unclean, be sure to bathe more frequently, wear loose pants, and keep the area ventilated and clean. Additionally, avoid spicy and irritating food, and try not to stay up late.
Is an infected sebaceous cyst serious?
Sebaceous cysts are benign proliferations resulting from excessive secretion by one's own sebaceous glands. These cysts accumulate under the skin and contain a bag filled with tofu-dregs-like substances. They may gradually grow and cause pain, though they do not lead to severe infections, so sebaceous cysts are not a symptom of serious infection. After identifying this condition, it is necessary to visit the dermatology department of a formal hospital, where a minor surgery can completely remove the cyst and the tofu-dregs-like substance to effectively cure the disease. After treatment, it is crucial to maintain a regulated diet and lifestyle, avoid spicy and stimulating food, refrain from staying up late, reduce sebaceous gland secretion, increase exercise, bathe frequently, and sweat more, all of which help prevent recurrence.
The contagious period of chickenpox is how many days?
Chickenpox is caused by a viral infection. This disease is quite contagious and is mostly transmitted through the air and respiratory system. The contagious period generally lasts about ten days, but it can vary from person to person, with some patients possibly experiencing a longer duration. Generally, children exhibit milder symptoms and have a shorter treatment period. In adults, the treatment period tends to be longer, typically ending when the symptoms have subsided and the blisters on the body have completely dried and fallen off. Once this disease is contracted, it is essential to isolate and treat it properly using antiviral medications. Children and elderly individuals in the household should avoid frequent contact to prevent transmission. After the onset of chickenpox, high fever may occur, so it is necessary to have some fever-reducing medications on hand to prevent other illnesses caused by the fever.
Athlete's foot, what is it?
Tinea manuum and tinea pedis are diseases caused by fungal infections. These diseases have a high incidence rate, are highly contagious, and tend to recur. They typically occur due to exposure to external fungal infections, which initiate erosion on the surface of the palms or soles and gradually infiltrate the deeper layers of the skin. This can lead to peeling or blistering, and the itching can be intense. These conditions are also quite contagious. Once this disease occurs, it is essential to seek proper medical treatment. Treatment can be administered at a dermatology department of a standard hospital using antifungal creams applied twice daily. Persisting with the treatment for one to two months can lead to a complete recovery. After recovery, it is crucial to maintain a proper diet and lifestyle habits. Avoid public baths and swimming pools, do not share flip-flops, and ensure that used items are disinfected by exposure to sunlight.
What are the instruments for vitiligo examination?
The most commonly used instruments for diagnosing vitiligo currently are the Wood's lamp and the dermatoscope, with the Wood's lamp being used slightly more frequently in clinical settings. After the appearance of white patches on the body, one can first visit the dermatology department of a formal hospital for an examination with the Wood's lamp. If it is vitiligo, the patches will appear brightly white under the lamp, with clear edges. This disease has a certain degree of recurrence, and it is crucial to undergo formal treatment once diagnosed. During treatment, it is advisable to enhance physical exercise, boost immunity, and largely avoid eating spicy and irritating foods. Treatment can include oral medication, topical medication, and the use of a 308 nm UVB laser, which can accelerate recovery. It's beneficial to consume foods rich in black pigments, and it is advisable to avoid consuming excessive amounts of Vitamin C-rich foods. Persisting with the treatment usually yields good results.
Does vitiligo spread through contagion?
Vitiligo is not contagious, and it will not be transmitted to others through contact once it appears. However, this disease does tend to have a genetic predisposition. The main factors contributing to vitiligo include decreased immunity, a deficiency of copper in the body, localized trauma, or genetic heredity. There are also some reasons that cannot be fully identified through medical examination. After vitiligo appears, its progression varies from person to person. Some patients experience rapid development, with the affected area expanding significantly within a few months, while others see slower progression. Generally, if the spread is quick, it is necessary to seek routine treatment promptly. If the affected area is small and the progression is very slow, it might be reasonable to observe for a while to monitor the development of the patches before deciding on the treatment approach. In any case, it is crucial to take vitiligo seriously upon its onset, continuously observe its progression, consult a doctor to assess the severity of the condition, and receive appropriate treatment.
Symptoms of infectious genital warts
Genital warts are caused by a papillomavirus infection and are a type of sexually transmitted disease, mainly spread through sexual contact. They frequently occur on mucous membranes such as the foreskin, glans, vulva, anal area, or mouth. Initially, a small granulation tissue appears, which gradually proliferates, enlarges, or multiplies, exhibiting a cauliflower-like growth. If the warts grow larger, the surface tissue becomes fragile, and lightly scratching may dislodge a piece of tissue, potentially causing bleeding. Once this disease occurs, it is essential to seek professional treatment at a dermatology department in a reputable hospital, as the disease is highly contagious and prone to recurrence, resulting in a lengthy treatment period. Sexual contact should be avoided until completely cured to prevent transmission to others.
What are the transmission routes of genital herpes?
Genital herpes is caused by the herpes simplex virus type 2 infection, with the primary transmission route being sexual contact. However, some patients can also be infected through contact with contaminated clothing or through activities like bathing, swimming, or staying in hotels, although these methods have a relatively lower chance of transmission. Once infected with genital herpes, it generally persists for life and cannot be completely eradicated. Antiviral medications such as valacyclovir can be used during outbreaks, and topical acyclovir ointment can be applied locally. Regular exercise and consuming medications that enhance the immune system can help reduce the recurrence of this disease. If one frequently stays up late or consumes spicy and irritative food, the likelihood of recurrence increases. Moreover, this disease is highly contagious during outbreaks and can be transmitted to others through sexual contact.
How to treat acne scar bumps?
Acne scars and keloids are often caused by improper treatment of acne or by scratching, squeezing, and breaking the skin during the treatment process, leading to infection and the subsequent formation of these scars and keloids. Once formed, it is impossible to completely remove them. If the keloid scars are not particularly prominent, you can visit a dermatology department at a standard hospital to repair them with fractional laser treatment. If the keloid scars are very noticeable and proliferative, you can also visit a dermatology department at a standard hospital for drug injection treatment, but it is not possible to completely remove them, only to temporarily relieve the symptoms. If the scars are relatively small, cosmetic surgery to excise them can be an option. Therefore, during the treatment of acne, it is crucial to follow standard practices and timely treatment, and to avoid scratching or squeezing the skin to prevent the formation of keloid scars.
