What are filamentous warts?
Filiform warts are a type of skin disease caused by the human papillomavirus infection, and they belong to a kind of common warts, often seen in women, with a certain degree of contagiosity. They are usually related to a decline in the body’s immune function. For example, in cancer patients or those with HIV where the immune system is compromised, filiform warts can easily occur. The clinical presentation of filiform warts typically includes brown or light brown lesions, some of which match the normal skin tone. They appear as elongated, soft, pedunculated growths and can vary in number from several to several hundred. They generally occur on eyelids, neck, and scalp among other areas. For the treatment of filiform warts, options under medical guidance include using carbon dioxide laser therapy, cryotherapy with liquid nitrogen, or removal through high-frequency electrical ion cauterization.
How to treat an ingrown toenail that has become infected and pus-filled?
Paronychia with suppuration can be controlled by disinfecting the area with iodine and then applying anti-inflammatory ointments, typically mupirocin ointment or erythromycin ointment. If there is significant local swelling, it may be necessary to perform a lateral nail avulsion or nail removal under local anesthesia to ensure adequate drainage of the pus and control the infection effectively. After controlling the infection, for more severe cases of ingrown toenail deformity, it may require further correction of the nail and a procedure to reshape the nail groove to manage the inflammation and correct nail deformities. Treatment should also include oral antibiotics, taken under medical supervision, such as erythromycin tablets. Since paronychia with pus formation can easily lead to systemic infection, it is crucial to treat it aggressively.
How to treat paronychia
For acute paronychia, broad-spectrum antibiotics are mainly used for topical application. Options include mupirocin ointment, fusidic acid cream, or erythromycin ointment for symptomatic treatment. At the same time, it is important to wear loose shoes to avoid squeezing the foot and worsening the symptoms. If there is no improvement in symptoms after three days of using topical medications, surgical treatment may be considered based on the specific situation. For chronic paronychia, antibacterial or antifungal medications may be used. Medication should be gradually discontinued after the inflammation has subsided. During treatment, keep the affected area dry and avoid contact with water. Paronychia refers to an infection of the tissue surrounding the nail, typically presenting with localized swelling and pain.
How to determine if you have paronychia
To determine if it's paronychia, first there will be obvious swelling, pain around the nail, and sometimes exudation. Paronychia is usually caused by the penetration of a foreign object under the nail, or by trimming the nails too short. If the nails are trimmed irregularly and become embedded in the nail bed, this can also lead to paronychia. If there is obvious swelling, pain, and tenderness around the nail, paronychia should be considered. Paronychia is usually related to ingrown nails. For mild ingrown nails, topical application of iodine can gradually alleviate the paronychia. In cases of severe paronychia, it is necessary to visit a hospital where a doctor can perform a nail removal and also change dressings timely. Significant pain may require oral antibiotics treatment or intravenous antibiotics. During treatment, avoid alcohol and spicy, irritating foods.
How is urticaria caused?
There are many causes of hives, and the most common is related to genetics. If one of the parents has an allergic constitution, then the likelihood of allergies in their offspring significantly increases. Environmental factors also play a role in the occurrence of hives. For example, environments with a lot of dust or dust mites can trigger allergic reactions. Additionally, a humid living environment can promote the growth of fungi, which can also cause hives. The occurrence of hives is also related to food. Individuals who are allergic to proteins might experience hives when consuming high-protein foods like fish, shrimp, crabs, milk, and eggs. Furthermore, viral infections, bacterial infections, and parasite infections can also trigger hives.
What should I do if a filamentous wart breaks?
After a filiform wart breaks, it is important to avoid contact with water to prevent infection. Once a filiform wart is damaged and scabs form, you can visit a dermatology department at a reputable hospital for treatment. Some physical therapy methods used to remove these include liquid nitrogen freezing, carbon dioxide laser treatment, high-frequency ion therapy, and microwave treatment. These methods can effectively remove filiform warts. Recurrence of filiform warts may occur, so it is essential to regularly revisit the hospital for follow-up after treatment. Filiform warts are a type of viral skin infection, which is related to a decline in the body's immune system. Therefore, it is important to rest adequately, avoid staying up late, exercise appropriately to enhance immune function, and maintain a light diet, avoiding spicy and irritating foods.
How to treat chronic urticaria?
Chronic urticaria often utilizes antihistamine medications to control symptoms, combined with Traditional Chinese Medicine (TCM) and differential diagnosis and treatment. Treating chronic urticaria generally requires long-term use of antihistamines, sometimes for two or three months, or even up to six months, a year, or more. Typically, treatment involves the combination of two or more types of antihistamines. For cases of chronic urticaria where antihistamines are ineffective, immunosuppressants may be used to adjust the body’s immune state, thus controlling the outbreaks of chronic urticaria. Chronic urticaria is a long-term, slow process that cannot be resolved quickly, so it is important to try to identify the triggering factors of chronic urticaria, or to identify specific allergens. However, finding the allergen is usually challenging because many patients with chronic urticaria have conditions that are also related to their own immune status.
What should I do if new warts grow around the area after freezing common warts?
After cryotherapy for common warts, it is common for new warts to appear around the treated area. This is because common warts are caused by an infection with the human papillomavirus (HPV), a type of viral skin disease that tends to recur. Persistence in treatment is necessary in such cases. Treatments such as liquid nitrogen cryotherapy, carbon dioxide laser therapy, or high-frequency electronic ion cautery can be used. The occurrence of common warts is usually related to decreased immune function in the body. Therefore, it might be beneficial to use immunomodulators, such as interferon or thymopeptides enteric capsules, which have certain inhibitory effects. Concurrently, some traditional Chinese medicines that clear heat and detoxify, soothe the wind and balance the liver, along with other topical Chinese herbal treatments, can be used. A combined approach of Chinese and Western medicine often results in better outcomes. It is also important to engage in appropriate exercise to boost the body's immune system.
Will rosacea relapse after laser treatment?
Rosacea laser treatment can lead to recurrence. Since rosacea itself is a hereditary disease, it is prone to relapse. Even with successful treatment, lack of care in daily life can lead to recurrence. Frequent staying up late, consuming spicy and stimulating foods, and drinking alcohol can also cause relapse. Therefore, even after rosacea has significantly improved through treatment, it is essential to be mindful in daily life. Try to avoid alcohol and hot drinks, and do not consume spicy foods like chili peppers. These foods can trigger vascular dilation in the skin, and once the blood vessels of a rosacea patient dilate, it becomes quite challenging to reverse, potentially worsening the symptoms. Also, avoid exposure to overly warm air conditioning, as it too can stimulate vascular dilation, causing irreversible skin damage.
What should I do if my face is severely swollen due to rosacea?
If rosacea appears and causes significant facial swelling, you can apply some anti-inflammatory drugs locally, such as Mupirocin ointment or Fusidic acid cream. It is also advisable to take oral anti-inflammatory drugs under the guidance of a doctor, typically choosing Doxycycline Hydrochloride capsules or Minocycline Hydrochloride capsules. Rosacea is a chronic inflammatory skin disease occurring on the face, primarily involving facial blood vessels, hair follicles, and sebaceous glands. The cheeks may exhibit episodic flushing accompanied by papules, pustules, and dilated capillaries, as well as uncomfortable sensations like itching and burning. If you have rosacea, it's important to choose appropriate facial cleansing products or use clean water to remove excess oil from the skin's surface. Also, pay attention to your diet, avoiding overly greasy, spicy, and irritating foods.
