Recently, we met several cases of mumps in primary and secondary school students on duty, and here we briefly introduce the etiology, clinical manifestations and treatment of mumps. 1. Etiology: Mumps is commonly known as mumps, also known as toadstool plague. It is an acute infectious disease characterized by painful swelling in the subauricular cheek area and is a common respiratory infection among children and adolescents. It is a common respiratory infection among children and adolescents. Modern research suggests that it is an acute non-suppurative inflammation of the parotid gland caused by a virus invading through the respiratory tract. 2, clinical manifestations: the onset of the disease is mostly acute, with fever, chills, headache, sore throat, poor appetite, nausea, vomiting, generalized pain, etc. A few hours to 1 to 2 days later, the parotid gland is significantly enlarged. The fever varies from 38 to 40°C, and the severity of symptoms is very inconsistent; adult patients are generally more severe. The swelling of the parotid gland is most characteristic, with one side swelling first, but there are also two sides swelling at the same time; usually centered on the earlobe, developing forward, backward and downward, pear-shaped and tough, with unclear edges. When the swelling of the gland is obvious, swelling and pain and sensory allergy appear, which is worse when chewing with the mouth open and eating an acidic diet. The skin is tense and shiny, with a burning surface, but is not red and is lightly painful to the touch. The cellular tissue surrounding the parotid gland may also be edematous, reaching up to the temporal and zygomatic arches, down to the jaw and neck, and also at the sternocleidomastoid muscle (occasionally edema may appear in front of the sternum), thus distorting the appearance. Most of the swelling of the parotid gland reaches its peak in 1 to 3 days and continues to subside and return to normal in 4 to 5 days. The entire course of the disease is about 10 to 14 days. In atypical cases, there may be no swelling of the parotid glands but symptoms of simple orchitis or meningoencephalitis, or swelling of the submandibular or sublingual glands only. The diagnosis can be confirmed by urine or blood amylase testing. 90% of patients have mild to moderate increases in serum amylase as measured by serum and urine amylase, and urine amylase is also elevated, which helps in the diagnosis. 3, treatment: the disease is contagious, once suspected need to isolate patients. By improving the patient’s diet, light diet, pay attention to warmth and rest, and antiviral symptomatic treatment, it can reduce the patient’s pain and shorten the course of treatment. In addition, Chinese herbal medicine treatment: use both internal and external treatment. Internal medicine is based on the formula of Puji Disinfectant Drink, which is added and reduced according to the evidence. Local external application can be applied with Zijin Ingot or Qing Dai San in vinegar, several times a day, or 30g of Jinhuang San and Hibiscus leaves, 9g of chrysanthemum juice with honey, 2 times a day, or pounded with dandelion, duck-plantar grass, daffodil root and horsetail, which can reduce local swelling and pain. The prognosis is mostly good. Individuals with serious complications. Such as heavy meningoencephalitis and myocarditis, nephritis, etc. must be handled with caution.
