[Stepwise biopsy in diagnosis of bronchial tuberculosis]
Abstract:
Stepwise forceps biopsy was used in 29 patients with different forms of pulmonary tuberculosis, which may ascertain the pattern of bronchial inflammation and the pathogenetic mechanisms of extension of an abnormal process to the bronchial wall, which is important in determining treatment policy. A specific process was found to spread to the bronchial wall from the focus of lesion in the lung tissue itself in a bronchogenic fashion in most (62%) cases and from the bronchopulmonary lymph nodes by contact (38%). There are also data on the impact of controlled short-term chemotherapy in 24 patients with tuberculosis and specific bronchial lesion. The controlled short-term chemotherapy has been found to be effective in slower abacillation rates.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
