How long will it take for hair follicles to necrose after hair loss?
Hair loss for about half a year can lead to the death of hair follicles. The death of hair follicles is usually caused by folliculitis, which is due to damage or blockage of the follicles, leading to redness, itching, and pain in the center of the follicle, appearance of papules and pustules, and in severe cases, ruptured pustules that crust over and form permanent skin damage, such as scars and hair loss. Therefore, it is crucial to seek medical attention promptly upon signs of folliculitis. Diagnosis can be confirmed through physical skin examinations, laboratory tests, and pus examination. Timely treatment usually involves the application of topical antibiotics like Mupirocin ointment, topical corticosteroids such as Budesonide ointment, and for patients with poor response to topical medication, ultraviolet light treatment of the infected area may be chosen. (Medication should be used under the guidance of a doctor.)
Can washing your hair with vinegar cure tinea capitis?
Washing the scalp with vinegar for tinea capitis can only play a minor treatment role and cannot cure it. Tinea capitis is a skin disease caused by fungal infections and requires treatment with antifungal medications. For example, topical application of clotrimazole cream or terbinafine cream can be used, along with antifungal shampoos such as selenium sulfide shampoo or ketoconazole shampoo. Patients with severe tinea capitis may also need oral medication treatment, such as taking itraconazole capsules or terbinafine tablets. It is advisable not to self-medicate tinea capitis, and systematic treatment should be sought at a hospital.
How is hyperhidrosis of the hands and feet treated?
The patient suffers from palmar-plantar hyperhidrosis, which can be treated using antiperspirants or botulinum toxin injections. Palmar-plantar hyperhidrosis is primarily about controlling sweat secretion and is caused by a disorder in the sympathetic nervous system function. In treatment, antiperspirants used mainly contain aluminum salt compounds, such as 20% aluminum chloride. It should be used according to the doctor's instructions, every three to five days. Typically, dryness and flaking of the skin occur after using the medication, and timely skin care is necessary. Botulinum toxin injections can also be used to treat palmar-plantar hyperhidrosis. Botulinum toxin can inhibit the action of acetylcholine at local nerve endings, which also has a therapeutic effect on local hyperhidrosis. Moreover, the effect lasts relatively long, maintaining about six months.
How to deal with big toe paronychia on your own?
The patient with an ingrown toenail managed it themselves, requiring minimized activity and elevating the foot to promote local circulation. Additionally, topical disinfectants such as iodine tincture can be used, not merely applied, but used for moist dressing. Take some cotton soaked in iodine tincture and apply it to the swollen area around the nail fold, generally recommending a five to ten-minute application. Antibiotic ointments can also be applied externally, such as mupirocin cream. After application, cover it for two hours, and treat it two to three times a day. If this method does not effectively alleviate the pain, consider taking antibiotics that have previously caused no allergies, with a preference for cephalosporins or penicillin-type antibiotics. If the antibiotics still do not effectively relieve the pain, it is advised to seek medical attention at a hospital. (Use medications under the guidance of a doctor.)
How long is the incubation period for sexually transmitted diseases?
The incubation period of sexually transmitted diseases (STDs) varies, which is a rather general question. Firstly, it is important for patients to understand what STDs are; they are a collective term for sexually transmitted infections, consisting of various diseases such as HIV/AIDS, syphilis, genital warts, and gonorrhea, which are among the most common. STDs share a common characteristic of being transmitted through high-risk sexual behaviors. Typically, the incubation period for syphilis is 40 to 90 days, for HIV it is about three months, genital warts can have an incubation period ranging from three months to half a year, and gonorrhea tends to manifest symptoms quickly. Once infected with gonorrhea, symptoms such as abnormal discharge, discomfort during urination, frequent urination, urgent urination, and painful urination may appear within a week. Therefore, if one engages in high-risk sexual behaviors and wishes to be reassured through testing, it is advisable to visit a hospital for a medical examination after a week.
How to treat sexually transmitted diseases?
The treatment of sexually transmitted diseases (STDs) cannot be generalized, as different STDs require different treatment approaches, and there are many types of STDs with completely distinct treatment methods. Some STDs are caused by viral infections and require antiviral medication for treatment. Other STDs result from bacterial infections or other pathogens, typically necessitating the use of antimicrobial and antibacterial drugs. Furthermore, some STDs, like genital warts, are primarily treated with physical therapy, usually without the need for oral or topical medications for follow-up treatment. Therefore, before treatment, it is crucial to identify the specific type of STD and select a targeted treatment plan based on the disease.
Can acne and pimples wear a mask?
The patient has acne and chooses to wear a mask, which does have a certain impact on the acne. The acne appears around the mouth area, and wearing a mask will cover the affected area. Although it can protect one's health, it may exacerbate the symptoms of acne. Active treatment for acne is necessary, involving proper hydration by drinking small amounts of water frequently and maintaining a light diet, including foods high in vitamins. When going out, it is crucial to wear a mask for personal safety, especially during the epidemic prevention phase. More attention should be paid to self-protection. After returning home, the acne-affected area should be promptly treated with medication, and cleanliness and hygiene should be maintained.
Can paronychia heal by itself?
Paronychia cannot heal on its own; it definitely requires timely treatment at a hospital. If not treated promptly, the condition could worsen and may even necessitate surgical removal of parts of the nail bed or keratin. Upon detecting paronychia, it's important to first clean the affected area thoroughly. Applications such as iodine tincture can be used topically, and soaking in boric acid or alcohol is also possible. During recovery, it is advisable to avoid spicy and greasy foods. Additionally, it's crucial to quickly begin antimicrobial treatment. Antibiotics can be taken orally or administered via intravenous drip to treat the infection systemically, such as amoxicillin. Ichthyol ointment can be applied to the swollen areas, but any medication should be used following a doctor's prescription. During the treatment period, it is recommended to consume a diet high in protein and fiber, especially foods rich in vitamin C like kiwifruit and passion fruit.
How to treat paronychia when it becomes purulent?
Paronychia has already become suppurative and needs timely treatment. Patients can choose to use medications to clean the affected area, which can prevent the condition from worsening. Paronychia is not a very serious disease, but improper care or worsening of the condition can lead to suppuration and cause severe symptoms. It is considered that the condition may be caused by accidentally injuring the surrounding soft tissue when trimming nails or by wearing tight shoes. If the patient's condition is severe, it is best to go to a formal hospital for timely examination and diagnosis. The suppurative area can be incised, and anti-inflammatory medications can be applied to avoid severe local infections. During the recovery period, patients should maintain a light diet and avoid spicy foods.
Vitiligo is what kind of disease?
Albinism is a congenital hereditary skin disease, which primarily manifests as the pigment loss or localized, or complete depigmentation of the skin, hair, and eyes. Clinically, it can be categorized into localized albinism and generalized albinism. The onset of the disease may be significantly related to defects in certain genes, hence it has a strong genetic component. Its manifestation includes whitening of the skin and hair, as well as loss of pigment in the eyes. Due to the lack of pigment, symptoms may include photophobia, tearing, and a decrease in vision. Currently, there are no particularly effective treatments for albinism. The main approach includes avoiding light exposure and applying sunblocks and ointments to prevent the occurrence of skin tumors.
