Factors correlated with tuberculosis reported after death
1Centers for Disease Control, Ministry of Health and Welfare, Taipei, Taiwan.
Setting:
Taiwan.
Objective:
To determine factors associated with tuberculosis (TB) reported after death.
Design:
A retrospective cohort study was conducted of TB patients newly registered between 2006 and 2008. The national TB database was linked with the Vital Registry System and National Health Insurance database for analysis.
Results:
A total of 1409 (4.0%) TB cases were reported after death. Age ⩾75 years (OR 1.70), chest X-ray (CXR) unknown or not performed (OR 2.41), positive sputum bacteriology (OR 1.74), and comorbidities such as cancer (OR 1.21), chronic liver disease (OR 1.21) and chronic kidney disease (OR 2.58) were associated with the reporting of TB cases after death. More than 30% of TB deaths in elderly persons with chronic kidney disease were TB cases that were reported after death. Abnormal CXR and comorbidities such as chronic obstructive pulmonary disease, stroke and diabetes mellitus were less likely to be associated with the reporting of TB cases after death.
Conclusions:
Elderly patients with cancer, chronic liver disease or chronic kidney disease require more attention to prevent delayed diagnosis and early mortality from TB. Elderly patients with chronic kidney disease are at highest risk.

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.

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...

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...

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...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
