Can paronychia be treated by oneself?
Paronychia generally should not be self-treated. The occurrence of paronychia is usually related to improper nail trimming or improper removal of hangnails; some are caused by bacterial infections, while others are due to fungal infections. It is advised not to self-treat paronychia, especially if there is an abscess, as it requires proper medical treatment at a hospital. Improper handling can easily lead to worsening of the infection, and pus drainage treatment should be conducted under the guidance of a doctor. If swelling and pain are significant, oral antibiotics might be necessary. In cases where there is no allergy to antibiotics, oral medications such as cefaclor sustained-release tablets or cefdinir dispersible tablets may be used. Attention should also be paid to the cleanliness of the affected area to avoid squeezing it oneself.
Early symptoms of syphilis
Syphilis is a chronic, systemic sexually transmitted disease caused by the Treponema pallidum bacterium. It is highly contagious and very harmful. The early symptoms of syphilis usually include the appearance of a chancre. Typically, about three weeks after infection, a hard, painless, round nodule appears at the site of infection. It starts as a reddish, moist spot, then gradually becomes ulcerated and eroded, forming an ulcer. This is an early manifestation of syphilis, known as a chancre. The harm caused by syphilis is very significant. Once syphilis is diagnosed, it is crucial to start treatment early. Early prevention of syphilis is essential, and any early symptoms should be taken very seriously. Treatment can be administered under a doctor's guidance, usually involving the muscle injection of long-acting penicillin. (Under the guidance of a doctor for medication.)
Signs before the regression of flat warts
Signs before the regression of flat warts include slight itching in some people, or a numb sensation in others. During the healing process of flat warts, immune cells repair the local skin lesions and release inflammatory factors, causing mild itching. The rash of the flat warts will also turn red, gradually shrink, and then scab over. If the flat warts have been treated with liquid nitrogen freezing or laser, there might be some pain before they regress. However, before the regression of flat warts, many people do not show any special symptoms and most people's flat warts regress unknowingly. The occurrence of flat warts is due to a viral infection, and they can be removed under the guidance of a doctor using liquid nitrogen freezing treatment or laser methods.
What does it mean when erysipelas causes the skin to break and discharge fluid?
Erysipelas with ruptured skin and oozing fluid primarily occurs due to a lack of timely treatment after the onset of erysipelas. The surrounding skin becomes damaged and starts to discharge fluid, but this "flow" is not actual water; it is various liquids. This situation results from skin ruptures where inflammatory substances and pus slowly seep out, creating a flow of fluid. When erysipelas occurs, it is crucial to treat it proactively under the guidance of a doctor using anti-inflammatory medications. Locally, mupirocin ointment or fusidic acid cream can be applied. Oral medications can include erythromycin dispersible tablets and cephalosporin antibiotics, following the doctor's advice. (Medicate under the guidance of a doctor)
What is eczematous dermatitis?
Eczematous dermatitis is a manifestation of dermatitis, with the main clinical manifestations being millet-sized papules, vesicopustules, or vesicles on the skin, accompanied by erythema that can merge into patchy areas. Frequent scratching can lead to exudation, erosion, secondary infection, and in severe cases, the formation of pustules and crusts. Eczematous dermatitis is a type of allergic skin disease. It is usually necessary to identify the specific allergens involved. One can visit a hospital to check for allergens and then undergo treatment with antihistamines as directed by a doctor. If there is significant exudation, topical treatment can include wet dressings with lactic acid, ichthammol solution, or boric acid solution. Treatment can also be supplemented with traditional Chinese medicine and Western medicine combined, based on differential diagnosis.
What vitamins are needed for alopecia areata?
For alopecia areata, supplementing with Vitamin B and calcium pantothenate can aid in hair regrowth. However, alopecia areata is not solely caused by vitamin deficiency; it is largely related to genetics and psychological factors. Stress, anxiety, depression, frequent late nights, insomnia, and poor rest can contribute to this condition. Immune factors can also lead to alopecia areata. In cases of alopecia areata, besides daily oral vitamin supplements, if the condition is severe, it is advisable to seek treatment under the guidance of a physician. This may include treatment based on Traditional Chinese Medicine (TCM) diagnostics, or taking Chinese patent medicine such as "Yan Xie Sheng Fa" capsules and "Qi Bao Mei Ran" pills, which nourish the blood and promote hair growth. Additionally, integrating Western medicines like L-cysteine tablets and compound glycyrrhizin capsules can also be helpful.
Initial symptoms of genital warts in women
The initial symptoms of genital warts in women are usually some pale red, soft, and tiny papules which then gradually increase in size and number. These papules may merge with each other, with some overlapping, and the surface becomes rough, resembling cauliflower or cockscomb, or nipple-like formations. If the area is moist and warm or exposed to chronic irritation, the warts can grow more rapidly. Generally, genital warts in women, after being infiltrated by secretions, turn a dirty grey or red color and have a rather soft texture. The base of the genital warts usually has some stalk-like structures. Some genital warts may erode and exude fluid, which also makes them prone to secondary bacterial infections, leading to foul smells. Genital warts in women are primarily caused by the human papillomavirus infection, and the treatment typically involves the use of methods like carbon dioxide laser or cryotherapy with liquid nitrogen.
What are the common causes of hair loss?
The most common cause of hair loss is generally related to genetic factors. For instance, if parents experience hair loss, their children are likely to encounter the same issue. Hair loss can also be associated with hormonal imbalances; an excessive secretion of male hormones can lead to hair loss. It is related to infection factors as well, such as infection with Malassezia bacteria on the scalp, which can cause erythema and papules on the head, and significant hair loss with dandruff. Psychological factors also play a significant role in hair loss. Excessive mental stress, anxiety, and poor sleep can lead to the release of stress-related substances by the body, causing the hair follicle growth cycle to shorten and leading to hair loss. Therefore, it is advisable to visit a dermatology department at a reputable hospital for a timely examination to identify the specific causes and undergo treatment under a doctor's guidance with appropriate medications.
The difference between eczema and prickly heat
Eczema and heat rash have clear differences, distinguished by their causes, affected areas, and symptoms. The cause of heat rash is mainly due to blocked sweat pores, typically triggered by hot and humid environmental conditions; eczema, on the other hand, is usually caused by allergic factors such as food allergies, pollen, dust mites, animal fur, etc., and is also related to disorders of gastrointestinal function and indigestion. The seasonal occurrence of the two conditions also differs. Heat rash usually occurs in the summer, while eczema can occur in any season and at any age. The affected areas are also different. Heat rash typically appears on the chest, back, inside the elbows, neck, and forehead, whereas eczema can occur on any part of the body. The clinical manifestations of the two are also different; heat rash involves inflammation of the sweat glands, with the skin turning red and a dense distribution of papules. Eczema, on the other hand, primarily features symmetrically distributed erythema and papules, and may also include exudation.
What should I do if I have itchy skin?
If you experience itchy skin, it is advisable to visit a hospital to determine the cause. Some cases of skin itchiness are caused by internal diseases such as thyroid disorders, renal insufficiency, diabetes, and cholestasis. Other cases may be due to conditions like eczema, urticaria, or papular urticaria. If the skin itchiness is not accompanied by other unusual symptoms, it may be considered pruritus. Treatment should be under the guidance of a doctor, using antiallergic medications such as loratadine tablets, chlorpheniramine maleate tablets, and mizolastine tablets. For conditions like eczema and papular urticaria, as well as drug-related dermatitis, topical antipruritic medications like mometasone furoate gel and Lushengshi wash can be applied. These should be used in conjunction with oral antiallergic drugs. (Medication should be used under the guidance of a doctor.)
