Peachy sputum is a common clinical manifestation of pulmonary schistosomiasis. Lung schistosomiasis, also known as pulmonary schistosomiasis, is an acute or chronic endemic parasitic disease caused by Schistosoma haematobium. The parasites are mainly found in the lungs, with cough and peachy sputum as the main manifestations, but also in various tissues and organs, such as the brain, spinal cord, gastrointestinal tract, abdominal cavity and subcutaneous tissue, producing corresponding symptoms. The clinical manifestations are also diverse. The incubation period ranges from a few days to 20 years, mostly within 1 year. The disease starts slowly with mild fever, night sweats, fatigue, loss of appetite, cough, chest pain and brownish-red jam-like sputum. There is abdominal pain, diarrhea, nausea, vomiting, and the discharge of brownish-brown sticky pus and blood stools. Allergic symptoms such as urticaria. Acute pulmonary schistosomiasis has a more acute onset with high fever and toxemia. Low back pain, difficulty moving lower limbs, even paraplegia, difficulty urinating and defecating, incontinence. Pleural effusion signs may be complicated by pleural thickening or abscess chest. Cystic masses, enlargement of mesenteric lymph nodes, liver, spleen and testes, and peritoneal effusion may be palpable in the abdomen. Meningeal irritation signs, hemianopia, abnormal or absent sensation, and optic nerve papilla edema. A few patients have epilepsy, convulsions, hemiparesis, and motor disorders. History of eating uncooked stone crabs or mayflies in areas where the disease is endemic. Long-term cough, hemoptysis, brown jam-like sputum, some with low-grade fever, night sweats, few pulmonary signs, with corresponding signs when combined with pleural fluid, Sichuan pulmonary schistosomiasis can also be seen in the abdomen, thoracic back and other places of wandering subcutaneous nodules or masses. The diagnosis can be confirmed by a significant increase in blood eosinophils, direct smear of sputum or 24-hour concentration method to find the eggs of pulmonary schistosomes. （X-ray examination: round or oval infiltrative shadows with blurred margins, single or multifocal cystic shadows in the lungs, faint and variable lung shadows, lesions in the middle and lower lung fields, often accompanied by a small amount of pleural effusion. Intradermal test for adult Schistosoma lungworm antigen, posterior caecal membrane test and/or complement binding test for Schistosoma lungworm are positive. Biopsy of subcutaneous nodules or masses may reveal eosinophilic granulomas with eggs or larvae of Schistosoma lungeri. How to effectively prevent rotten peach-like blood sputum? Do hygiene education, do not eat raw or uncooked stream crabs, larvae and other 2nd intermediate hosts, do not drink raw stream water in infected areas, treat patients thoroughly and control the source of infection. Prevent eggs from entering the water, trap and destroy intermediate hosts. The principle of treatment for acute respiratory obstruction is to treat the cause and symptomatic treatment in addition to sedation and oxygenation. In case of abscess in the posterior pharyngeal wall, incision and drainage should be made. For acute laryngitis, larynx, trachea and bronchitis, in addition to adequate antibiotics, adrenal corticosteroids should be given to reduce exudative edema. For severe laryngeal obstruction, nasotracheal intubation or tracheotomy should be performed. Foreign bodies in the larynx, trachea and bronchus should be removed under laryngoscopy or bronchoscopy. For asthma attacks caused by bronchial smooth muscle spasm, bronchodilators should be given to relieve the bronchospasm.
