- 放射学 放射学是一门学科.
背景情况:
- 结核病 (TB) 预防策略需要有针对性的优先级.
- 大规模结核病查提供了一个机会,以确定高风险的个体.
研究的目的:
- 在大规模查干预后,根据老年人的不同基线胸部X射线发现来评估结核病发病率.
- 为了评估患结核病的风险,在异常与正常胸部X射线结果的个体中.
主要方法:
- 从2020年3月到2022年10月,在中国东部的183,808名老年参与者中进行了大规模结核查.
- 参与者根据基线胸部X射线结果 (活跃,稳定,不确定,正常) 进行了分类.
- 在两年内追踪结核病发病率,并对疑似病例进行进一步的诊断测试 (CT,培养,GeneXpert).
主要成果:
- 在X射线异常的参与者中,每10万人年结核病的年化发病率明显高于X射线异常的参与者:1,525 (活跃),278 (稳定) 和325 (不确定),相比之下是61 (正常).

Pulmonary Tuberculosis IV
469
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
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...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pneumothorax-II
874
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
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...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.
