2 English reference Paragonimus miyazaki
Overview of pulmonary paragonimiasis is a lung disease caused by Miyazaki paragonimiasis. Patients have lived or traveled in paragonimiasis endemic areas, especially in contact with raw or undercooked crabs or crayfish or drinking streams. It takes about 1 month to half a year to eat crabs raw. Patients may have chest pain, cough, back pain, shortness of breath, abdominal pain, chest tightness, blood phlegm and other symptoms. Mainly chest pain and cough.
There are some clinical differences between paragonimiasis miyazaki and paragonimiasis westermani, which need to be differentiated. Trichlorophenol is effective in treating Miyazaki paragonimiasis, and it can be completely cured as long as it is diagnosed and treated early. If there are many complications, the prognosis is poor.

8 Epidemiology There are nearly 48 known insect species in the world, of which 3 1 species is the most widely distributed in Asia. The main subtypes that cause diseases to humans are Wechsler, Wechsler, Sichuan, Huitong, Isopan, Tuanshan, Miyazaki and Paragonimus daping. Paragonimus westermani and Paragonimus skrjabini are the main pathogenic insects in China. Paragonimus miyazaki is very common in Japan.
9 The cause of paragonimiasis Miyazaki paragonimiasis is the main pathogen. Patients have lived or traveled in paragonimiasis endemic areas, especially in contact with raw or undercooked crabs or crayfish or drinking streams.
10 Pathogenesis Human consumption, salting and drinking of echinococcosis containing paragonimiasis or river shrimp are polluted. After echinococcosis is swallowed into human body, the cyst wall is broken under the action of digestive juice. Child worms escape, enter the lungs through the intestinal wall, destroy lung tissue, and form insect cysts to settle down.
1 1 clinical manifestations of pulmonary miyazaki paragonimiasis patients usually have abdominal symptoms such as abdominal pain after eating crabs 1 month to half a year. According to the 3 1 case records reported in Japan, the symptoms are chest pain 12 cases, cough 8 cases, back pain 6 cases, shortness of breath 5 cases, abdominal pain 3 cases, chest tightness 2 cases, blood sputum 2 cases, asymptomatic 4 cases, and the record is unknown 1 case.
12 complications of pulmonary miyazaki paragonimiasis can form pleurisy, pneumothorax, lung abscess and other complications.
In 13, eosinophils in peripheral blood were examined in laboratory, and 1 case was less than 10%, 6 cases were 10% ~ 20%, 6 cases were 20% ~ 30%, 6 cases were 30% ~ 40%, and 4 cases were 40.
14 auxiliary examination X-ray chest film showed pleural effusion in 24 cases, pneumothorax 12 cases, intrapulmonary shadow in 5 cases, pleural adhesion in 3 cases and enlarged heart shadow in 2 cases.
15 diagnosis of miyazaki paragonimiasis. According to the clinical manifestations, the main symptoms of pulmonary miyazaki paragonimiasis are chest pain and cough.
2. There are many cavitary lung lesions, and the lesions are polymorphic (round, oval, rectangular and polygonal).
3. The number of eosinophils in peripheral blood is high.
16 differential diagnosis of pulmonary miyazaki paragonimiasis and westermani paragonimiasis: ① chest pain and cough are the main symptoms of this disease, and hemoptysis and blood sputum are the most common symptoms of the latter; ② On chest radiograph, the most common manifestation of this disease is lung shadow, and the latter is mainly pneumothorax and pleural effusion. ③ The higher eosinophil count in peripheral blood is due to the heterotopic parasitism and disorientation of this trematode, which is higher than 30% in most cases and 50% or even 70% in a few cases. Almost all blood IgE values have increased. Akiji Suzuki and others think that the difference between this disease and pneumocystis is that there are many hollow lesions in the lung, which are polymorphic (round, oval and plastic) and multilocular; And the treatment of this disease is more difficult and time-consuming than the latter.
17 for the treatment of paragonimiasis in Miyazaki, thiophenol 35mg/kg is taken on 1 day, 1 time the next day, and * * 1 5 times is1cycle, or two cycles can be used.
18 The prognosis of pulmonary Miyazaki paragonimiasis can be completely cured as long as it is diagnosed and treated early. If there are many complications, the prognosis is poor.
19 prevention of paragonimiasis in Miyazaki is the same as that of Paragonimus westermani.
