What causes rubella?
Rubella is primarily caused by an infection of the rubella virus, a type of acute respiratory contagious disease. Once rubella occurs, it is transmitted through respiratory droplets, and children are more susceptible to this disease. Patients with rubella are the only source of infection. The rubella virus is transmitted through respiratory droplets and close personal contact. If pregnant women are infected with rubella, especially during the early stages of pregnancy, the virus can be transmitted to the fetus through the placenta. Rubella is caused by the rubella virus infection, but certain conditions are required such as a decrease in the body's resistance or the absence of antibodies against the rubella virus in the body, which can lead to the development of rubella. Clinically, it is usually characterized by mild fever, widespread small and unevenly sized papules across the body, and swollen lymph nodes behind the ears, on the neck, and at the base of the skull.
Will tinea capitis be contagious if someone touches it?
If someone with tinea capitis briefly makes contact, it generally isn't contagious. If the skin is washed promptly with soapy water after contact, it will not lead to infection. It is important to maintain cleanliness, wash hands frequently, and wash hands thoroughly to minimize the risk of infection. Tinea capitis is a contagious skin disease caused by a superficial fungal infection of the scalp. Hats, pillows, and combs used by individuals with tinea capitis can have many fungi attached to them, and using these combs or wearing hats, using the pillows can easily lead to fungal infections. If tinea capitis occurs, it is important to use antifungal medications promptly for treatment. Under a doctor's guidance, using ketoconazole topical shampoo can be effective, and in severe cases, it may be necessary to combine this with oral antifungal medications for treatment.
How long does the hair loss phase of alopecia areata usually last?
The shedding phase of alopecia areata generally lasts about three months. Alopecia areata refers to the sudden occurrence of patchy hair loss on the top of the head, usually caused by excessive mental stress, fatigue, and disorders of the immune system. Alopecia areata typically arises when various factors cause the hair follicles on the scalp to shift from the growth phase to the resting phase, resulting in the hair no longer growing and subsequently falling out extensively. The occurrence of alopecia areata is also somewhat related to genetics. If dieting leads to malnutrition, alopecia areata may also occur. The clinical manifestation of alopecia areata is the appearance of round or oval patches of hair loss on the top of the head. Some occur individually, while others may appear in multiples, varying in size and without any subjective symptoms. If alopecia areata occurs, it is advisable to seek diagnosis and treatment in the dermatology department of a standard hospital.
How to deal with seborrheic dermatitis?
For seborrheic dermatitis, topical application of some corticosteroid medications like desonide ointment or hydrocortisone butyrate cream can be utilized. However, it is important to avoid prolonged, excessive use on the more delicate facial skin. In cases of oozing or erosion, treatments such as boric acid solution or saline can be used for wet compresses. Additionally, for seborrheic dermatitis, one may also choose calcineurin inhibitors like tacrolimus ointment or pimecrolimus cream. If severe itching occurs with seborrheic dermatitis, symptomatic itch relief should be provided, primarily through oral antihistamines such as desloratadine dispersible tablets or cetirizine hydrochloride tablets. Treatment can also include traditional Chinese medicine based on differential diagnosis.
At what stage should a corn plaster be considered effective?
When applying corn plaster, it is essential to apply it until the area of the corn turns white, remove the white callus, and then continue to apply the plaster. Keep applying until the surrounding skin no longer turns white, leaving only the protruding corn. Once the root of the corn has also necrotized, it can be pulled out from the root. If there is still pain when pulling out the corn, continue using the medication. When the dead skin on the corn turns white, clean, with clear lines, and the newly exposed tender skin is smooth, clean, with clear lines, and there is no pain when pressed, this condition indicates recovery. Corns generally occur due to prolonged pressure on the foot or wearing tight shoes, causing sustained pressure and friction over time.
What causes alopecia areata on the head?
Spots of baldness on the head can be associated with many reasons, usually due to excessive mental stress. Being in a state of tension and anxiety for a long period can easily lead to the occurrence of bald spots. Bald spots also have a certain relationship with genetic factors, generally related to family genetics. Frequent perming, hair dyeing, and other actions that damage hair quality can also lead to bald spots. Additionally, some endocrine disorders, immune factors, and infections such as fungi and bacteria, such as tinea capitis or folliculitis, can also cause bald spots. Therefore, if bald spots occur, it is recommended to promptly visit a dermatology department at a formal hospital for diagnosis and treatment. After the doctor identifies the specific cause, an appropriate treatment plan can be implemented, which may include oral cysteine tablets or choosing compound glycyrrhizin capsules and traditional Chinese medicine treatments.
How to cure allergic dermatitis?
To cure allergic dermatitis, the first step is to identify the allergen. Once identified, you can avoid it and use medication in combination, which can completely cure this type of dermatitis. When allergic dermatitis occurs, it is crucial to actively eliminate the allergen and supplement with oral antihistamine medications, as well as traditional Chinese medicine. Treatment should involve a combination of Chinese and Western medicine. Allergic dermatitis must be detected and treated early. Treating this allergy-related skin disease in its mild stages can prevent recurrence. It is also important to persist with medication under a doctor's guidance, as stopping medication midway through treatment or due to fear of side effects can lead to a relapse. For those suffering from allergic dermatitis, diet should also be considered; avoid seafood, shellfish, and spicy or irritating foods.
How to cure allergic dermatitis completely?
To fundamentally treat allergic dermatitis, it is essential to first clarify the cause and identify which allergen triggers it to avoid contact. In terms of treatment, it often involves a combination of oral and topical medications. Oral medications typically include antihistamines, such as loratadine dispersible tablets, cetirizine tablets, or fexofenadine hydrochloride tablets. These can be supplemented with compound glycyrrhizin tablets or vitamin C tablets, calcium gluconate, or treatment based on Traditional Chinese Medicine differential diagnosis. For topical use, corticosteroid ointments or calcineurin inhibitors can be chosen to help. Regular skin care is crucial, using moisturizing lotions to maintain the barrier function of the skin, making it less susceptible to irritation and reducing the chance of recurrent allergic dermatitis. (Medication should be used under the guidance of a physician.)
How to distinguish eczema from prickly heat
Eczema and heat rash have clear differences, including different causes. Eczema is primarily caused by allergens, as well as excessive mental stress, anxiety, and hormonal imbalances. Heat rash, on the other hand, usually arises from overly humid and hot environments that affect normal sweating function, leading to blocked sweat ducts. Their clinical manifestations also differ. Eczema typically presents as polymorphic and symmetrically distributed lesions, usually manifesting as papules and vesicular papules, and in severe cases, erosion, exudation, and significant itching are observed. Heat rash clinically appears as tiny, pin-sized blisters that emerge in clusters and merge into patches, typically found at skin folds without symmetry. White heat rash generally has less noticeable itching, whereas red heat rash is itchy and can also feel burning.
Is syringoma related to sweating?
Syringoma has little to do with sweating. Syringoma, also known as eccrine acrospiroma or eccrine hidrocystoma, is a type of small sweat gland tumor that differentiates towards sweat ducts. It is inherited in an autosomal dominant pattern. During sweating, due to obstructed sweat flow, the syringoma, or the tumor mass, may increase in size. If syringoma appears, it may not require treatment. If it is considered cosmetically undesirable, treatment options include using carbon dioxide laser or cryotherapy with liquid nitrogen. With the occurrence of syringoma, it is advisable to avoid consuming excessively greasy foods and spicy, irritating foods in the diet. While syringoma is not significantly related to sweating, it is somewhat associated with frequent staying up late and irregular life routines.
