Abstract:
We report two cases of agenesis of the right pulmonary veins (PVs) associated with sequestration of the right lung with systemic to pulmonary collateral. Both the children were referred for evaluation of recurrent lower respiratory tract infections. Transthoracic echocardiographic evaluation showed reversal of flow in the right pulmonary artery (PA) and absent right PVs. Cardiac catheterization confirmed the diagnosis of agenesis of the right PVs. Transcatheter closure of collaterals was performed in view of significant shunt from systemic to PA. Both the patients are asymptomatic on follow-up.

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...

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...
