Pulmonary hookworm disease
Introduction
Introduction to pulmonary hookworm disease After being invaded into the human body through the skin or mucous membrane, the hookworm filamentous sputum enters the lung through the lymphatic or bloodway, and penetrates the pulmonary capillaries into the alveoli, causing punctiform hemorrhage and inflammatory cell infiltration. The pathological changes in the lung are similar to those of pulmonary ascariasis. Infection can form pulmonary lobular consolidation and bronchitis. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: contagious Complications: anemia
Cause
Cause of pulmonary hookworm disease
(1) Causes of the disease
The hookworm eggs develop through epidermal growth into infectious filamentous mites, which invade the human body from the skin mucosa. Farmland operations are an important source of infection.
(two) pathogenesis
After being invaded into the human body through the skin or mucous membrane, the hookworm filamentous sputum enters the lung through the lymphatic or bloodway, and penetrates the pulmonary capillaries into the alveoli, causing punctiform hemorrhage and inflammatory cell infiltration. The pathological changes in the lung are similar to those of pulmonary ascariasis. Infection can form pulmonary lobular consolidation and bronchitis.
Prevention
Lung hookworm disease prevention
Focus on strengthening publicity, promoting the harmless treatment of manure, reforming fertilization and farming methods, and conducting regular census and general treatment in epidemic areas.
Complication
Pulmonary hookworm disease complications Complications anemia
Combined with anemia.
Symptom
Pulmonary hookworm symptoms Common symptoms Acute sputum dry cough low heat papules chest tightness lung texture increased
The patient's hands exposed to contaminants often have small bleeding spots, papules, small herpes, and itching, ie, stagnation dermatitis, or low fever, itchy itch, pain, dry cough, blood in the sputum, and even massive hemoptysis. Patients may have transient asthma, chest tightness, wheezing and other symptoms of asthma-like episodes, physical examination may have scattered dry or wet voice, laboratory examination of peripheral blood leukocytes increased or even leukemia-like reactions, eosinophils to mild to moderate increase X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X Half to one month disappeared.
Examine
Examination of hookworm disease in the lungs
Examination of peripheral blood leukocytes increased or even leukemia-like reactions, the number of eosinophils increased to moderate to moderate, sputum examination may find filiform sputum.
X-ray chest radiographs may have blurred or enlarged hilar shadows, increased lung texture, flaky or nodular shadows, and X-rays of the lungs disappear in half to one month.
Diagnosis
Diagnosis and diagnosis of hookworm disease in the lung
In the endemic areas, there is a history of barefoot and manure, and anemia and other manifestations should be suspected of hookworm disease. The diagnosis can be confirmed by stool examination.
Pulmonary hookworm disease needs to be differentiated from bacterial pneumonia and lung tumors.
