Is Mycoplasma infection in children contagious?
Is mycoplasma infection in children contagious? Mycoplasma infection is a type of respiratory pathogen. It is generally transmitted through coughing and sneezing, directly via the upper respiratory tract, and can be contagious through close contact at short distances. Therefore, mycoplasma is contagious and has infectious properties. However, it is not classified as a communicable disease and its infectiousness is relatively weak compared to others. It is mainly transmitted through the respiratory tract, and everyday activities such as drinking and eating do not spread the infection.
What should I do if my baby gets keratitis?
Infants with keratitis should visit the hospital for an examination as soon as possible. Some children might not cooperate well, requiring experienced doctors to assist in the examination to determine the cause and provide symptomatic treatment. Concurrently, etiological treatment should be administered. Initially, local antibiotics should be used for anti-infection treatment. If the keratitis is caused by a viral infection, antiviral medication can be appropriately used. If the condition worsens, the patient should be checked once a day or once every two days. Once there is an improvement, a follow-up check is generally required every three days. Additionally, it is important to monitor for any corneal damage, and if necessary, medications for corneal repair should be used.
Can baby eczema cause fever?
Does infant eczema cause fever? Generally, this is not the case. Eczema is an allergic disease, characterized by the appearance of rashes on the skin due to an allergic reaction; fever typically does not occur in this case. If a baby develops a fever, the first consideration should be whether it is a cold. The second consideration should be whether there are any other infections present. Fever is generally considered to be caused by infectious factors, such as bacteria, viruses, mycoplasma, chlamydia, etc. Therefore, it is essential to identify the pathogen and determine the cause of the fever.
Hand, foot, and mouth disease is spread through:
Hand, foot, and mouth disease is an infectious disease caused by enteroviruses. There are more than 20 types of enteroviruses that can cause the disease, among which Coxsackievirus A16 and Enterovirus 71 are the most common. It frequently occurs in children under the age of 5 and manifests as mouth pain, loss of appetite, low fever, and small blisters or ulcers on the hands, feet, and mouth. Most affected children can recover within about a week. The main routes of transmission for hand, foot, and mouth disease can include the gastrointestinal tract, as well as respiratory transmission, and close contact such as through saliva, cough droplets, etc. Sharing utensils can also spread the disease.
What should I do if I find out my child is maturing early?
Interventional treatment for precocious puberty varies according to different causes. In principle, once diagnosed with central precocious puberty, aggressive pharmacological treatment is recommended, using inhibitory hormones to suppress development to pre-pubertal levels and inhibit further development of the ovaries and uterus. For peripheral precocious puberty or pseudoprecocious puberty, the cause must be removed. Clinically, if a child accidentally ingests their mother's contraceptive pills causing transient vaginal bleeding, it is essential to carefully inquire about the medical history, thoroughly understand the cause, and determine the treatment method. Also, ask if there has been any special dietary intake recently, including foods or drinks high in estrogen, and if so, remove the cause for treatment.
Symptoms of baby encephalitis
Generally speaking, the symptoms of encephalitis in babies usually start with fever. Encephalitis is an infectious disease, and the majority of cases present with fever, which could be either high or low. Next is vomiting. Since small infants cannot express headache, they usually manifest symptoms through crying, irritability, and restlessness. Additionally, there might be lethargy and malaise. Some may experience seizures, and others might have stiff neck, characterized by rigidity of the neck and changes in muscle tone of the limbs, among other symptoms. These are all symptoms of encephalitis.
Does hand, foot and mouth disease hurt?
Hand, foot, and mouth disease is caused by an intestinal virus, mainly manifested in children as blisters on the hands, feet, mouth, and buttocks. Some cases may involve fever, while others may have no fever or only mild, low-grade fever. Oral and pharyngeal blisters are quite common, causing oral pain and discomfort. Many children who contract hand, foot, and mouth disease experience a decrease in appetite, which is related to oral and pharyngeal blisters causing pain that affects swallowing and eating.
How long should hand, foot, and mouth disease be isolated?
Hand, foot, and mouth disease is an infectious disease caused by enterovirus infection. There are more than 20 common types of enteroviruses, with Coxsackievirus A16 and Enterovirus 71 being the most common. The main clinical symptoms include fever, mouth pain, loss of appetite, and small blisters or ulcers on the hands, feet, and mouth. Most affected children can heal on their own in about a week, so ordinary cases can be isolated for about a week until all the rashes have crusted over and disappeared. However, for severe cases, the isolation period should be extended appropriately, possibly lasting 10-14 days, or even longer.
Phenylketonuria lacks what enzyme?
Phenylketonuria is an autosomal recessive genetic disorder primarily caused by mutations in the phenylalanine hydroxylase gene. This leads to reduced activity of phenylalanine hydroxylase, accumulation of phenylalanine and its metabolites in the body, and the onset of the disease. Phenylketonuria is the most common congenital amino acid metabolism disorder. Clinically, it is mainly characterized by intellectual developmental delays, light skin and hair pigmentation, and a mousey urine odor. The incidence of this disease varies by ethnicity and region. In China, the incidence is approximately 1 in 11,000.
What medicine should a child take for vomiting and a cold?
When a child has a cold and shows symptoms of vomiting, it is likely due to acute gastrointestinal symptoms. In this case, oral medications to protect the stomach, such as bifidobacterium, cimetidine, omeprazole, or other antiemetic drugs can be administered. Additionally, it is important to check if there are symptoms of tonsillitis or throat inflammation, as inflammation of the tonsils or throat can stimulate the gag reflex and also cause reflex vomiting. In this situation, the first step should be to control the symptoms of the throat and tonsils, which will gradually improve the vomiting. Also, pay attention to the child's body temperature and their mental responses.
