Thrombotic thrombocytopenic purpura seen as pulmonary hemorrhage
Abstract:
A 33-year-old woman was seen with fever, confusion, and respiratory distress. A diagnosis of thrombotic thrombocytopenic purpura (TTP) was made when renal failure, microangiopathic hemolytic anemia, and thrombocytopenia subsequently developed. An open kidney biopsy confirmed the clinical diagnosis. The patient initially was seen with the roentgenographic and clinical appearance of pulmonary hemorrhage, which was confirmed histologically and, to our knowledge, previously has not been associated with TTP.

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 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...

Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
Factors Affecting Pulmonary Ventilation
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...
