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.
Will hair regrow after hair loss from scalp ringworm?
Scalp ringworm causes hair loss, and whether hair will regrow depends on the severity and specific type of scalp ringworm. There are generally four types of scalp ringworm: yellow ringworm, white ringworm, black dot ringworm, and kerion. White ringworm is primarily caused by infection from Microsporum canis, Microsporum gypsum, or Trichophyton violaceum. It is common in school-aged children, starting with small clustered papules that quickly expand outward into round or oval shapes covered with gray-white scale. Hair affected by white ringworm protrudes 2-4 millimeters above the scalp before breaking off. This type of ringworm does not destroy the hair follicles, so it does not cause permanent hair loss. After treatment, no scars are left, and hair can regrow in the affected area. Yellow ringworm, commonly known as bald ringworm, affects hair follicles and destroys them, leading to significant permanent hair loss and leaving behind atrophic scars. Hair will not regrow after healing from this type of ringworm. Black dot ringworm is now less common. It directly affects the hair follicles, characterized by hair breaking off shortly after emerging, leaving black dot-like stumps at the follicle openings. As this is a type of fungal infection, the prognosis includes localized hair loss and spot-like atrophic scars; hence, hair will not regrow in these areas. Kerion is a more severe outbreak where honeycomb-like pus pockets are formed at the follicle openings, allowing pus to be expressed. Triggering bacterial infections can also lead to abscesses. This type also destroys hair follicles, resulting in permanent hair loss and scarring, without regrowth of hair.
What does it mean if there is fluid in athlete's foot?
Athlete's foot, also known as tinea pedis, commonly manifests in three types: vesicular, hyperkeratotic, and intertriginous. The vesicular type is characterized by blistering and scaling, typically occurring on the tips of the fingers, the palms, and the sides of the feet. Initially, the skin lesions appear as small, scattered blisters the size of a pinhead. The blister fluid is clear, and the blister walls are relatively thick. These blisters can cluster and merge to form larger blisters, eventually losing their walls to expose a honeycomb-like base and a raw, eroded surface. After several days, the blisters can dry out and flake off. As the condition progresses and exudation increases, it can develop into the intertriginous type, which primarily affects the web spaces between the fingers or toes. It is more common in people who sweat excessively, soak their feet in water, or wear rubber shoes for extended periods, particularly during the summer. The skin becomes soaked and appears whitish, with a soft surface that peels off easily, revealing a moist red eroded area with exudate, often accompanied by cracking and significant itching. When secondary bacterial infection occurs, there is typically an odor. If not promptly controlled, it can lead to secondary infections, producing pustules and ulcers, and may also lead to acute lymphangitis, lymphadenitis, cellulitis, or erysipelas. In severe or recurrent cases, it can also induce local eczematous changes and disseminated dermatophytosis.
How long is the latency period of syphilis?
Syphilis is a chronic infectious disease caused by the bacterium Treponema pallidum (TP), primarily transmitted through sexual contact and blood. The impact of syphilis is significant as it can affect all bodily tissues and organs, or can be transmitted through the placenta, leading to stillbirth, miscarriage, premature birth, and congenital infections. When syphilis is suspected, due to its complex clinical manifestations, a detailed medical history should be taken, a thorough physical examination conducted, and repeated laboratory tests performed to ensure an early and accurate diagnosis. It is important to trace back to any unprotected sexual contacts within the last six weeks and to routinely screen the sexual partners of patients for syphilis as well. Syphilis is divided into three stages: The diagnosis of primary syphilis is mainly based on the history of exposure, the incubation period (six weeks), typical clinical manifestations, and laboratory tests, noting that a negative syphilis serology result alone should not exclude the diagnosis of syphilis. The diagnosis of secondary syphilis primarily relies on the history of exposure, typical clinical manifestations, especially skin and mucosal lesions, combined with laboratory tests. The diagnosis of tertiary syphilis is mainly based on the history of exposure, typical clinical manifestations, and laboratory tests. Neurosyphilis can also be assessed through cerebrospinal fluid examination. Congenital syphilis primarily requires a maternal history of the disease, combined with typical clinical manifestations and laboratory tests for diagnosis.
Can people with eczema eat onions?
People with eczema should not eat onions. Eczema is caused by various internal and external factors, leading to inflammation in the superficial dermis and epidermis. Clinically, the acute lesions primarily consist of vesicular rashes accompanied by itching and a pronounced tendency for exudation. Chronic eczema is primarily characterized by lichenification and is prone to recurrence. Individuals with eczema should avoid onions because onions are spicy and irritating foods. Consuming onions can exacerbate the symptoms of eczema. During the treatment of eczema, patients should not eat foods that are hot in nature, nor spicy, irritating, or allergenic foods. A mild diet should be maintained, drinking plenty of water, and consuming more vegetables and fruits. Additionally, treatment of eczema involves protecting the skin; using moisturizing creams to nourish the skin and enhance its resistance. While bathing, it’s also important to ensure the water is not too hot and to avoid using alkaline soaps or detergents that could damage the skin’s epidermis.
