What is the difference between tinea capitis and seborrheic dermatitis?
Tinea capitis and seborrheic dermatitis have fundamentally different causes. Tinea capitis is a fungal infection, including conditions such as yellow tinea, white tinea, black dot tinea, and pustular tinea. It leads to the destruction of hair follicles, which can cause hair loss and even scarring. Seborrheic dermatitis, also known as seborrheic eczema, arises from the excessive secretion of sebum. At this time, it may also be stimulated by the colonization of certain microorganisms, such as Malassezia, causing inflammation. It typically affects the scalp, face, chest, and back. The initial lesions are follicular papules, which gradually enlarge and merge into dark red or yellow-red plaques covered with greasy scales or crusts. It can also exhibit exudation, crusting, erosion, and other eczematous changes, and in severe cases, the skin lesions can become widespread throughout the body. To differentiate between tinea capitis and seborrheic dermatitis, besides the symptoms, local skin flakes can be tested in a laboratory using fungal immunofluorescence, as well as bacterial and fungal cultures.
Can genital herpes virus be cured completely?
Genital herpes virus, due to its residual virus, remains latently stored in the sacral ganglia. When the body's resistance decreases or some triggering factors are present, the latent virus can be reactivated and recur. Therefore, genital herpes is difficult to completely cure. Genital herpes virus is a type of chronic, recurrent, hard-to-cure sexually transmitted disease caused by herpes simplex virus type 2 infecting the urogenital and perianal skin and mucous membranes. In the past 30 years, the incidence of this disease has been continuously rising. During treatment, patients need to rest, avoid alcohol, and excessive sexual activity. Sexual activity should be avoided when clinical symptoms occur. If genital herpes becomes active before delivery during pregnancy, a cesarean section should be performed. Treatment involves the use of topical antiviral drugs, and it is also important to prevent secondary bacterial infections.
Is urticaria contagious?
Urticaria, commonly known as hives, is not contagious. It is a localized edema of the skin and mucous membranes due to temporarily increased vascular permeability. Its pathological causes are not related to infection, thus it is not contagious. The specific cause of urticaria often remains unclear for many patients. Some cases are due to certain foods, such as animal proteins, seafood, fungi, and some food additives like tartrazine, balsam of Peru, and sulfites. Some cases are triggered by drugs such as penicillin and various vaccines. Others are caused by allergens inhaled through the respiratory tract or by contact with the skin; common examples include pollen, animal dander, dust, fungal spores, and dust mites, as well as some volatile cosmetics. Contact with certain items, such as insect bites, venomous insects, certain plants like nettles, or animal fur such as wool, can also trigger urticaria. Some cases may be related to physical factors such as exposure to cold, heat, sunlight, or pressure, all of which can potentially lead to the development of urticaria.
Can soaking feet in vinegar cure athlete's foot?
Athlete's foot, also known as tinea pedis, is a condition caused by skin fungal infections affecting the superficial layers of the skin on the feet. For treatment, one can opt for antifungal ointments, and when necessary, oral antifungal medications, which are very effective in killing fungi. However, using home remedies like soaking feet in white vinegar, salt water, or applying garlic locally is not advisable. These do not effectively kill the bacteria and can instead damage the skin barrier and irritate the skin, potentially causing symptoms such as redness, flaking, and itchy sensitivity. If the concentration of vinegar is too low, it is ineffective; if too high, it can be intolerable for the skin. Therefore, if you have athlete's foot, it is best to opt for proper antifungal medications and ensure treatment for a sufficient duration.
What causes asymptomatic gonorrhea?
Most patients with gonorrhea have clinical manifestations, and only a few with mild or chronic infections may not exhibit obvious symptoms. Gonorrhea is caused by an infection with Neisseria gonorrhoeae, commonly known as gonococcus. It primarily manifests as a purulent infection of the urinary and reproductive systems, and can also lead to pharyngeal, rectal, and disseminated gonococcal infections. It has a short incubation period, is highly contagious, and can lead to various complications and sequelae. Gonorrhea is mainly transmitted through sexual contact, with the patient being the source of infection. In rare cases, it can be contracted through contact with secretions containing gonococci or contaminated items, such as clothing, bedding, towels, bathtubs, and toilet seats. Females, including young girls, due to the short length of the urethra and genitalia, are easily infected. It is often through shared family use of bath items and towels that infection occurs. Newborns can be infected through the birth canal of a mother with gonorrhea, leading to neonatal gonococcal conjunctivitis. Pregnant women infected with gonorrhea may transmit the bacteria to the amniotic fluid, potentially infecting the fetus.
What are the symptoms of syphilis?
Syphilis is divided into acquired syphilis and congenital syphilis, which is transmitted via the fetus. Acquired syphilis, based on the duration of the disease and using two years as a boundary, is further divided into early-stage syphilis and late-stage syphilis. Early-stage syphilis, particularly primary syphilis, mainly presents symptoms such as a chancre and scleradenitis, generally without systemic symptoms. Secondary syphilis occurs when primary syphilis is untreated or not completely treated, allowing the virus to enter the bloodstream from the lymphatic system and spread throughout the body. This causes damages to the skin, mucous membranes, and systemically, known as secondary syphilis. It can manifest as various forms of syphilitic rash, some resembling papular rashes, others similar to dermatitis, eczema, flat lichen, urticaria, psoriasis, pustular disease, and others. Some secondary syphilitic rashes are similar to flat genital warts, and sometimes syphilis can lead to alopecia. Syphilis can also affect mucous membranes, appearing in the mouth, tongue, pharynx, larynx, and genital mucous membranes, characterized by one or more areas of distinct erythema, vesicles, erosion, covered with a grayish-white membrane, generally painless. Some syphilis cases might affect bones, causing damage to bones and joints. Latent syphilis presents no obvious symptoms, and late-stage syphilis might involve the cardiovascular and nervous systems.
Has gonorrhea gotten better if there is no more pus discharge?
Gonorrhea no longer discharging pus does not necessarily indicate improvement. True improvement can only be confirmed by testing negative. The standard treatment for gonorrhea involves an intramuscular injection of cephalosporin-class medication. Symptoms must be completely controlled, and follow-up checks should be conducted two to three times subsequently. Only if all tests are negative can it be declared cured. If the disease is still detected, further treatment is necessary, and avoiding sexual activity during treatment is crucial. Sexual partners must also be examined. Common complications of gonorrhea include, in males, gonococcal urethritis, which due to improper treatment, alcohol abuse, or sexual activity, may develop further, spreading to the posterior urethra and causing complications such as posterior urethritis, prostatitis, seminal vesiculitis, and epididymitis. These conditions can cause repeated inflammation, leading to scars, urethral stricture, or even blockage of the vas deferens, potentially resulting in infertility. In females, the main complication is gonococcal pelvic inflammatory disease, including acute salpingitis, endometritis, secondary tubo-ovarian abscess and complications from rupture like pelvic cysts and peritonitis. Misdiagnosis or mistreatment can easily advance to pelvic and adnexal infections. Recurring episodes may cause fallopian tube constriction, leading to ectopic pregnancy, infertility, or chronic lower abdominal pain.
Should the peeling skin be removed after using medication for athlete's foot?
After applying medication for athlete's foot, you should not peel the skin off with your hands, as this can damage the surrounding tissue and potentially lead to further infections, acute lymphangitis, lymphadenitis, or erysipelas. When inflammation is obvious, it may also trigger localized eczematous changes or a systemic bacterial rash. There are two possibilities for peeling after medication: one is that the peeling is caused by the primary disease, such as hyperkeratotic tinea pedis, in which case strong desquamating agents like compound benzoic acid ointment can continue to be used. If necessary, occlusive dressings may also be applied. If the peeling is not caused by athlete's foot itself but by irritation from the medication, such as erosive soaking tinea pedis treated with 3% boric acid ointment that has dried out, then stop using irritating and strongly desquamating medications. Instead, it is recommended to use creams and ointments. (Please use medications under the guidance of a doctor.)
The cause of papular urticaria
Papular urticaria, also known as insect bite dermatitis, is commonly seen in children and individuals with lower resistance and sensitive skin. It is caused by bites from insects such as mosquitoes and mites. The resulting skin reaction varies from person to person and is characterized by red patches and blisters. According to Traditional Chinese Medicine, it can be categorized into damp-heat type and wind-heat type. The wind-heat type usually occurs on the limbs, while the damp-heat type is more common around the waist and features larger and more numerous blisters. This condition is related to insect bites, commonly from mosquitoes, lice, fleas, mites, bedbugs, etc. After being bitten, the saliva injected into the skin may trigger an allergic reaction in the body.
Is shaving the head useful for hair loss?
Shaving your head when you lose hair does not clearly help alleviate the symptoms. However, cutting your hair short appropriately can reduce the nutritional burden on our hair follicles and physical traction, which can somewhat help in the prevention and treatment of hair loss. Specific hair loss still requires systematic treatment and conditioning. When losing hair, you can take Chinese herbal medicine for conditioning. According to traditional Chinese medicine theory, hair loss is generally considered to be caused by blood deficiency or kidney deficiency. Moreover, excessive fatigue, staying up late, and hereditary factors can also lead to hair loss. Therefore, it's important to avoid excessive fatigue, rest adequately, sleep by 11 o'clock, avoid staying up late, increase nutrition appropriately, and include various vegetables and fruits rich in vitamins C, A, B, and E in the diet. If necessary, some medications that supplement blood and nourish the kidneys can be taken orally.
