1.What is Mycoplasma pneumoniae and how does he make children sick? Mycoplasma is a microorganism smaller than bacteria, but larger than viruses; it invades the human body, mainly in the cell survival. Isolated from the human body of 16 kinds of mycoplasma, 5 kinds of human pathogenicity, of which Mycoplasma pneumoniae is to make the baby sick “culprit”. When the patient sneezes, coughs, or close contact with the patient. Mycoplasma pneumoniae will be spread with droplets, into the infected baby’s respiratory tract, causing respiratory infections in children. And a very common scam or over-treatment case is that some hospitals will detect mycoplasma in the cells of the pharyngeal swabs and other parts of the body as Mycoplasma pneumoniae infections to be treated, in fact, this is not true, because the colonization of mycoplasma does not mean that the infection, and other types of mycoplasma are generally not pathogenic to children. 2.Mycoplasma pneumoniae is easy to infect which children and how to prevent it? From the transmission route of Mycoplasma pneumoniae can be known, Mycoplasma pneumoniae mainly through droplet transmission, so if there is a Mycoplasma infection in the family, or the child goes to school, participate in collective life, collective Mycoplasma infected patients, may be infected. It is usually prevalent in children around 3 years old. The method of prevention is, if there is a cough in the family, wear a mask to prevent the spread, and pay attention to hand washing, because many droplet diseases are spread to each other through the hands of children. 3. What are the symptoms of Mycoplasma pneumoniae infection and how is it diagnosed? Most of the symptoms of Mycoplasma pneumoniae infection are pharyngitis, rhinitis, bronchitis and capillary bronchitis. The cough is dry in the early stage, and then it turns into persistent and severe cough without sputum or with a small amount of mucous sputum, especially coughing at night, and infants and young children show wheezing and respiratory distress. As long as it is treated in time, it rarely turns into pneumonia. Children of different ages behave differently. The younger the child, the less fever there is and may only have a cough, but children under 1 year old may wheeze more if infected. Older children may have a high fever that lasts for days. If a child over 4 years of age has an unexplained high fever that is not treated with conventional infections, Mycoplasma infection must be considered. Mycoplasma infection is generally used to exclude the method, because from the spectrum of childhood diseases, viral and bacterial infections caused by the most common, followed by allergy-induced respiratory inflammation, if the child’s cough and other symptoms can not be relieved in accordance with the previous two cases of treatment, we should consider the mycoplasma infection, it is more meaningful is the mycoplasma antibody titer test, if the child has relevant symptoms, found that mycoplasma antibody progressive elevation The most important thing to remember is that mycoplasma is not a disease that can be diagnosed. 4.How to treat Mycoplasma pneumoniae infection? The key to the treatment of Mycoplasma pneumoniae infection is the selection of antimicrobial agents, because Mycoplasma mainly exists in the cell, and often used cephalosporins, penicillin antimicrobial agents in the intracellular concentration is very low, the effect will be relatively poor. Nowadays, azithromycin and erythromycin are generally used for treatment, and Xisumi is especially recommended because the drug is purified better and more effective, and many grass-roots hospitals do not have this kind of drug, which leads to incomplete treatment of the child and recurrent episodes. As for the cough caused by Mycoplasma pneumoniae infection, nebulization is a better auxiliary treatment. Nebulization is through a specific machine or high-flow airflow impact, the drug) is dispersed into tiny droplets or particles, so that it is suspended in the gas, and into the respiratory tract and lungs, to achieve clean airway, purify the airway, local treatment (antispasmodic – anti-inflammatory – expectorant) and systemic therapy purposes. Because of the direct entry into the respiratory tract to play a role in the use of small doses of drugs, than oral or injection effects are better. 5.How long is the course of treatment for Mycoplasma pneumoniae infection? When to stop? Because of the survival of Mycoplasma pneumoniae in the cell, so to completely kill, the course of treatment needs to be long, to Xisumi treatment, for example, generally Xisumi treatment for 3 days, stop for 4 days for a course of treatment, Mycoplasma infections generally require treatment for 4-6 courses of treatment, and to be completely free of coughing, fever symptoms for more than 3 days, too early to stop the drug, insufficient treatment is prone to recurrence. 6, Mycoplasma pneumoniae antibody titer has not decreased, is it necessary to keep treating? Because children infected with Mycoplasma pneumoniae, Mycoplasma antibody titer may exist in the body for as long as 3-6 months, so we diagnose Mycoplasma pneumoniae infection theoretically should be at least two times to draw blood, to see the titer continues to rise, in order to confirm the diagnosis, but because of the traumatic nature of the blood draw, generally do not need to draw blood many times, through the child’s symptoms can be diagnosed. The success of treatment is still judged by the symptoms, which means that as long as the symptoms disappear and the course of treatment is sufficient, the medication can be discontinued boldly without waiting for the antibody titer to drop completely. Similarly, because of the nature of mycoplasma antibody titers, there is a misconception that leads to overtreatment of Mycoplasma pneumoniae infection. Because the child’s cough is a very common symptom, often parents or inexperienced doctors, see the child’s cough, previous Mycoplasma pneumoniae infection, check the mycoplasma antibody titer several times, see the titer is high, according to the mycoplasma infection to treatment, in fact, it is not right, because the mycoplasma infection must be the exclusion of the diagnosis, the emergence of a specific dry cough, fever, to rule out the ordinary bacterial and viral infections, and to rule out the allergy Cough caused by the combination of mycoplasma antibody titer results to do the treatment, otherwise, simply based on the titer results for diagnosis and treatment is often ineffective, and a waste of drugs. It is not uncommon to see a child with an obvious productive cough and a history of allergy with a recurrent cough that has been treated many times as a mycoplasma infection.
