What are the functions of pulmonary tuberculosis pathological sections?

Everyone knows that pulmonary tuberculosis is very harmful to the human body. Not only is the treatment process of this disease very long, but it is also highly contagious. If it is not treated in time, many organs in the human body will be damaged. The symptoms of pulmonary tuberculosis are necrosis of tuberculous nodules, which will form cavities, often causing patients to have low fever and fatigue. So what are the functions of pulmonary tuberculosis pathological sections?

First, what are the functions of pulmonary tuberculosis pathological sections? Generally speaking, one is to confirm whether it is a tuberculosis infection, and the other is to rule out lung tumors. Pathological diagnosis belongs to the highest diagnostic standard. If the pathological diagnosis confirms the presence of tuberculous lesions, then pulmonary tuberculosis is confirmed without a doubt.

Second, there is dry cough in the early stage, and when the cavity is formed and infected, the sputum is mucopurulent or purulent, hemoptysis, chest pain, and in severe cases, dyspnea. Ask about contact history or previous history of pleurisy, cervical lymphadenopathy, and BCG exposure. There are symptoms of tuberculosis poisoning, such as low fever, general malaise, fatigue, night sweats, loss of appetite, flushed cheeks, etc. Miliary and caseous conditions are often accompanied by high fever, some may be accompanied by joint pain, and women may have disorders. Early lesions are small in area or located deep in the lung tissue, and may show no abnormal signs. The lesion is large and respiratory movement on the affected side is reduced. Percussion is dull.

Third, the selective use of CT in diagnosis can make up for the shortcomings of chest X-ray examination. The tuberculin test is of greater diagnostic significance for infants, and a positive result under 3 years of age indicates activity. Chest X-ray examination uses fluoroscopy, posteroanterior chest radiograph, anterior arch radiograph, spot radiograph, apex radiograph, and tomographic radiograph. Active cases often have a mild increase in white blood cell count. In acute miliary disease, the white blood cell count may decrease, and sometimes a blood picture with a similar reaction may occur. In most cases, active tuberculosis bacteria can be detected in sputum. Generally, when the smear test is negative, a concentration method test should be performed. If the test result is negative after repeated testing, culture should be performed.

What are the functions of pulmonary tuberculosis pathological sections? The most reliable method for diagnosing pulmonary tuberculosis is pathological sections.

However, tissue specimens of pulmonary tuberculosis are not easy to obtain. If only a small amount of specimens are obtained by bronchoscopy, it is still difficult to determine whether it is tuberculosis. If necessary, the help of thoracoscopy may be needed.
