How long will it take for alopecia areata to fully recover once fuzz has started to grow?
Alopecia areata, once showing new fuzz, usually takes three to six months to return to normal. The appearance of fuzz indicates that the alopecia areata is in the recovery phase. In the early recovery stage, lighter-colored fuzz will grow in the area where hair was lost, and this fuzz will gradually turn into normal hair. During the active phase of alopecia areata, there will be noticeable hair loss, while in the dormant phase, the hair loss will stop. Three to four months after the dormant phase, most patients enter the recovery phase, reaching the stage where this small fuzz appears. Hence, the appearance of such fuzz signifies that the alopecia areata is nearing recovery, and new hair will grow during this phase. There are many causes of alopecia areata; it is important to avoid staying up late regularly.
How to deal with a skin scald that has broken the skin?
After a skin burn breaks the skin, if the area is relatively small and there is no obvious swelling, a moisturizing burn ointment can be applied. If the area is larger and accompanied by some exudation and swelling, it is necessary to go to the hospital for timely treatment. Under the guidance of a doctor, antibiotic ointment should be applied, and oral antibiotics should be taken. Common choices include Cefalexin, Cefradine dispersible tablets, and erythromycin for anti-infection treatment. Antibiotics can be used if there is no allergic reaction to them. If severe burn symptoms occur, combined with serious infections, swelling, and significant exudation, it is crucial to go to the hospital for medical treatment immediately. Severe cases may require hospitalization. Do not scratch the skin yourself, and avoid spicy and irritating food.
How can tinea capitis be treated to eradicate it completely?
To achieve a radical cure for tinea capitis, it is first necessary to consider the extent of the condition. If the affected area is not very large, then topical medications may suffice. Common choices for antifungal topical medications include Terbinafine Hydrochloride Cream, Luliconazole Cream, Oxiconazole Nitrate Cream, or Ketoconazole Cream. If the tinea capitis is progressing and there is significant damage to the hair in the affected area, oral medication may be required for treatment. However, liver and kidney function tests should be conducted prior to this. If liver and kidney functions are normal, options include oral Itraconazole Dispersible Tablets, Terbinafine Hydrochloride Tablets, or Fluconazole Capsules. If the local hair condition is severe, it may be necessary to timely shave the head while ensuring cleanliness and hygiene of the scalp during treatment.
Will seborrheic dermatitis recur?
Seborrheic dermatitis is likely to recur. In cases of seborrheic dermatitis, oily skin can easily lead to recurrence. Additionally, an inappropriate diet, often consisting of spicy, irritating food, as well as fried and greasy food, and habitual late nights, can also easily lead to recurrence. Therefore, when seborrheic dermatitis occurs, it’s essential to maintain a light diet, avoiding spicy and irritating foods, and seek treatment under the guidance of a doctor. For topical use, one can choose corticosteroid medications, typically choices include desonide ointment or hydrocortisone butyrate cream. For oral medications, options include Vitamin B6 or a B-complex vitamin. If itching is significant, it might also be necessary to combine treatment with antihistamine medications.
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.
