Will keratosis pilaris fade after puberty?
Keratosis pilaris can potentially fade after puberty. This condition is a genetically induced skin disease characterized by abnormal keratinization around the hair follicles. The disease is more common among children and adolescents with dry skin, and the rash tends to diminish as one ages. Keratosis pilaris occurs due to keratinization at the openings of hair follicles, which affects the growth of fine hair, making the skin feel rough, similar to goosebumps. Currently, there is no cure for keratosis pilaris, but symptoms can be improved using certain medications. Topically, keratolytics or skin softeners can be applied to alleviate symptoms and smooth the skin. Additionally, taking oral vitamin A or consuming foods rich in vitamin A can be beneficial for this condition.
What is the difference between skin tags and filiform warts?
Skin tags and filiform warts are clearly distinct. Clinically, skin tags are a type of soft external appearance, a skin soft fibroma, non-infectious, and somewhat hereditary; on the other hand, filiform warts are caused by a viral infection, offering a raised, smooth growth on the skin surface, and are somewhat infectious. The causes of each are different: filiform warts are due to human papillomavirus infections and commonly occur on the face and neck; whereas skin tags are mainly caused by skin aging. Treatment for filiform warts typically involves the use of lasers or cryotherapy, while skin tags may also be removed surgically or treated effectively with liquid nitrogen cryotherapy. Thus, there are differences in both the causes and clinical presentations of the two.
What is hair loss lacking?
Hair loss is often related to deficiencies in vitamins such as vitamin A, vitamin B, and trace elements including iron, zinc, and calcium. It is also related to the lack of nutritional factors, such as a deficiency in high-quality protein, which can lead to hair loss. Hair loss can be associated with many factors, including nutrition, diet, neurological and mental factors, as well as certain diseases including endocrine disorders and immune system diseases that can cause hair loss. Therefore, when experiencing hair loss, it's important to carefully analyze the reasons, and visit a hospital to determine the specific causes. If the cause is a deficiency in trace elements and vitamins, appropriate supplements should be provided. If it is caused by diseases, timely treatment of the primary disease is necessary. In terms of diet, it is also important to consume foods rich in protein and vitamins.
Is it good for psoriasis to be exposed to the sun?
Sun exposure can be beneficial for psoriasis, but it should not be for excessively long periods. When you have psoriasis, you should choose the right time for sun exposure. In winter, when the sunlight is gentler, it is appropriate to sunbathe, and you can also sunbathe indoors behind glass. In the summer, it is important to choose the right time, such as early morning or evening when the sunlight is not too intense, to enhance the skin's tolerance in psoriasis patients, allowing for normal sun exposure. Additionally, it is important for individuals with psoriasis to engage in appropriate exercise to boost immune function. During bouts of psoriasis, attention must also be paid to diet, avoiding spicy and irritating foods, avoiding staying up late, and following a doctor's guidance in using Chinese herbal medicine, Western medicine, or a combination of both, which typically yields a relatively ideal treatment outcome.
Methods for Curing Chronic Urticaria
Chronic urticaria is relatively difficult to cure completely. Clinically, antihistamine drugs are usually chosen for treatment. Options include fexofenadine hydrochloride tablets, olopatadine hydrochloride tablets, or levocetirizine dihydrochloride tablets. If conventional medications do not effectively control chronic urticaria, low-dose hormone therapy or immunosuppressants may also be considered. Additionally, since chronic urticaria is somewhat related to a decrease in body immunity, it is necessary to use drugs that enhance the immune system alongside treatment. Traditional Chinese medicine (TCM) and therapies tailored to individual conditions can also be used. Furthermore, acupuncture, cupping, and acupoint injection are treatment methods that can be effective for managing chronic urticaria.
How long does it take for common warts to fall off after they turn black?
After common warts turn black, they generally fall off within about a week. Common warts, also known as verruca vulgaris, are primarily caused by infection with the human papillomavirus, typically by the type 2 HPV virus. The occurrence of common warts is associated with numerous factors; they often arise when the body's immune system is weakened, or when warts already present are frequently scratched, which can lead to inoculation infection. Common warts can occur on various parts of the body and are commonly found on the hands. The hands are particularly susceptible if they are kept in water for prolonged periods, which can easily trigger the appearance of common warts. Typical lesions of common warts are pea-sized or larger, gray-brown or brown papules with a rough surface and hard texture, forming papillomatous proliferations. If common warts appear, treatment options such as liquid nitrogen freezing or carbon dioxide laser treatment are available at hospitals.
Can sulfur soap be used to wash hair for seborrheic alopecia?
If you are experiencing seborrheic hair loss, it is not recommended to use sulfur soap for shampooing. This is because sulfur has a degreasing effect and can treat seborrheic dermatitis, but sulfur is irritating to the scalp. Its strong degreasing effect on the scalp can alter the scalp's microecological environment, which is not conducive to the normal growth and recovery of hair. Therefore, it is not advisable to use sulfur soap for shampooing when experiencing seborrheic hair loss. With the advancement of science, many dandruff treatment and hair growth promoting skincare products can be used for shampooing. We can choose these types of products which cause less damage to the scalp barrier and are more gentle in degreasing, avoiding major irritation and facilitating the recovery of the scalp.
Is rosacea related to the endocrine system?
Rosacea is related to endocrine disorders. Rosacea is a chronic inflammatory skin disease characterized by central facial redness and dilated blood vessels. It is a common skin condition significantly linked to the endocrine system. It is usually caused by an increase in skin sebaceous glands due to the overgrowth of Propionibacterium acnes, excessive sebum secretion, and clogged pores, leading to symptoms like redness, papules, and pustules. When dealing with rosacea, attention should be paid to diet, avoiding staying up late, and avoiding excessive fatigue. Treatment should involve the use of Traditional Chinese Medicine (TCM) for differential diagnosis and treatment, or the use of anti-inflammatory medications under the guidance of a doctor, such as Minocycline capsules or Doxycycline hydrochloride capsules. Treatment can also be supplemented with red and blue light therapy.
Are common warts and flat warts caused by the same virus?
Common warts and flat warts are caused by infections of the same virus, mainly due to Human Papillomavirus (HPV), but not by the same type. There are over one hundred types of HPV, with more than eighty types associated with human diseases. The types of HPV that cause flat warts are mainly type 3 and type 5, while the types that cause common warts are mainly HPV type 1, type 2, type 4, and type 7. Therefore, common warts and flat warts are caused by different types of HPV infections. The appearance of flat warts and common warts is primarily due to minor lesions in the skin and mucous membranes, allowing the virus to enter the epithelial cells of the human body. There, the virus replicates and proliferates, leading to abnormal proliferation and differentiation of epithelial cells, forming benign growths on the epidermis.
Does albinism have anything to do with blood type?
Albinism is not related to blood type; it is related to genetics. Albinism is a skin and appendage disorder caused by a deficiency or reduced function of tyrosinase. It is somewhat related to hereditary factors, and also to the lack or synthesis obstruction of melanin. If both parents pass the pathogenic gene they carry to their children, then the children may develop this type of albinism. Ocular albinism is usually an X-linked recessive genetic disorder, mainly transmitted from mothers carrying the albinism gene to their sons, leading to the onset of the disease. Albinism is not directly related to blood type. If albinism occurs, it is advisable to consult and treat at a hospital, and to take preventive measures against the disease before pregnancy.
