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.)
What to do about hair loss during menopause?
Hair loss during menopause requires attention to nutrition. It is important to consume protein-rich foods to ensure hair nourishment. Additionally, consuming B vitamins like vitamin B2, B6, and B12 can help reduce oiliness and follicle clogging in the hair. It is also important to enhance iron absorption and metabolic nutrition to avoid damage to hair follicles and hair itself. Proper hair care is crucial: maintain cleanliness and protect the scalp, and avoid frequent hair perming and dyeing that could damage the hair. Traditional Chinese Medicine (TCM) can also be used to target treatment based on differential diagnosis, including taking specific pre-prepared TCM formulas like nourishing blood and generating essence capsules. When going outdoors, it is also important to protect against sun exposure to prevent hair damage and reduce hair loss. Moreover, it is beneficial to maintain a positive mood, regularly massage the scalp, and avoid staying up late.
How to remove the red marks left by syringoma
The red marks left after the treatment of syringoma are relatively normal, and over time, many marks left after surgery will fade on their own. After surgery, when scabbing and flaking occur, there are usually some marks. Under the guidance of a doctor, one can choose to apply epidermal growth factor gel to the localized skin to promote skin metabolism, reduce pigmentation, and eliminate the red marks. For red marks left after syringoma surgery, in addition to topical medications, one can also alleviate them through dietary means. In terms of diet, consuming more foods rich in Vitamin C and Vitamin E can speed up metabolism, gradually reducing the intensity of the red marks and also maintaining cleanliness and hygiene of the localized skin area.
If vitiligo is not treated, what are the consequences?
If albinism is not treated, it can have serious consequences. Primarily, albinism affects the pigmentation of hair and the retina at the back of the eye. Lack of pigment in the retina can lead to photophobia, and some individuals may experience nystagmus, with severe cases showing a significant decrease in vision. The vision of some individuals with albinism may range between 0.05 to 0.1, which has a significant impact on eyesight. If left untreated, albinism also greatly affects the skin. Individuals with albinism are sensitive to light and are prone to skin cancer under strong ultraviolet radiation. Moreover, some rare types of albinism can cause a decrease in platelet function, leading to a tendency to bleed at a certain age, as well as pulmonary fibrosis. Albinism is primarily a genetic condition caused by mutations and is linked to heredity. The main issue in albinism is a disruption in melanin formation, leading to reduced pigmentation.
How long does it take for papular urticaria to be considered chronic?
Papular urticaria is usually referred to as insect bite dermatitis, with the course of the condition generally lasting about a week; if it extends beyond a week, it is considered chronic. The occurrence of papular urticaria is associated with bites from mosquitoes, mites, fleas, etc. In terms of treatment, topical applications such as calamine lotion or corticosteroid creams can be used, including mometasone furoate gel and hydrocortisone butyrate cream. For significant itching, oral antihistamines can also be taken, such as fexofenadine hydrochloride tablets or cetirizine hydrochloride oral solution, while avoiding washing with hot water.
Chronic urticaria has persisted for two years and has not improved for a long time. What should I do?
Chronic urticaria, which has persisted for two years, requires a treatment approach combining Chinese and Western medicines. It is necessary to use some anti-allergic medications which can be selected under a doctor's guidance, such as Ketotifen Fumarate Tablets, Desloratadine Dispersible Tablets, Olopatadine Hydrochloride Tablets, and Chlorcyclizine Hydrochloride Tablets. Additionally, combining Chinese traditional medicine or patented Chinese medicine such as Cicada Itch-Relief Capsules and Moisture-Nourishing Itch-Relief Capsules can be beneficial. Urticaria is a type of chronic skin, an allergic skin disease, characterized by complex causes and stubborn conditions, often resulting in poor treatment outcomes and frequent relapses. Chronic urticaria mainly presents with erythema and wheals, accompanied by itching. It is important to avoid contact with allergens when experiencing chronic urticaria. Dietary restrictions, especially avoiding high-protein foods and pungent items, are also crucial. (Medications should be used under the guidance of a doctor.)
Is it good to wash your hair frequently if you have seborrheic hair loss?
Frequent shampooing is not good for those experiencing seborrheic hair loss. This is because frequent washing does not alleviate symptoms of seborrheic hair loss. For oily scalps, shampooing temporarily reduces oiliness, but washing too often can lead to a buildup of chemical residues, causing scalp inflammation and worsening hair loss. Frequent shampooing also damages the scalp's lipid barrier, leading to temporary dryness and scalp dermatitis, further exacerbating hair loss. Therefore, frequent shampooing is not recommended for those with seborrheic hair loss. For individuals experiencing seborrheic hair loss, it is advisable to visit a dermatologist at a reputable hospital promptly. Under the guidance of a doctor, appropriate medication and lifestyle advice can effectively cure the condition.
How to determine if you have contracted a sexually transmitted disease
Common sexually transmitted diseases include gonorrhea, syphilis, genital warts, AIDS, genital herpes, etc. When a sexually transmitted disease occurs, there are usually some special symptoms. In women, there are often purulent secretions in the vagina and local swelling and pain; men may experience burning, itching, and swelling at the urethral opening, along with some sticky secretions, often accompanied by frequent urination, urgent urination, and painful urination. If it's syphilis, there is usually a hard lump in the genital area with superficial ulcers, which is a manifestation of primary chancre. In patients with genital warts, there typically appear nipple-like or cauliflower-like growths around the genitals and anus. If infected with HIV, the early stages usually involve fever, as well as symptoms like nausea, vomiting, whole-body rash, and swollen lymph nodes.
What should be paid attention to in daily life for albinism?
For those with albinism, it is crucial to avoid sunlight exposure, especially during strong ultraviolet radiation. It’s advisable to minimize going outdoors or use sun-protection tools such as wearing long-sleeved clothing, hats, and sunglasses to reduce direct UV damage to the eyes and skin. For patients with a syndromic type of albinism, once a genetic diagnosis is confirmed, it is essential to inform the doctor about the condition when undergoing dental extractions or major surgeries, so that preventive measures against bleeding can be prepared. Furthermore, patients with albinism must seek genetic counseling and reproductive guidance before marriage and childbirth. If skin lesions are mild in the early stages of albinism, proactive cooperation with medical staff and a diet rich in vitamins are recommended.
