X-ray and CT of ground glass opacities and pneumothorax in pneumocystis pneumonia. Diagnosis of Pneumocystis pneumonia is by identifying the organism from a sample of sputum, fluid from affected lungs or a biopsy. [4] [3] A chest X-ray of affected lungs show widespread shadowing in both lungs, with a "bat-wing" pattern and ground glass appearance.
Pneumocystis pneumonia (PCP), also known as Pneumocystis jirovecii pneumonia (PJP), is a form of pneumonia that is caused by the yeast-like fungus Pneumocystis jirovecii. [ 3 ] [ 4 ] Pneumocystis specimens are commonly found in the lungs of healthy people although it is usually not a cause for disease. [ 5 ]
A report they jointly wrote and published in the June 5, 1981, issue of Morbidity and Mortality Weekly Report, described their patients as "5 young men, all active homosexuals, [who] were treated for biopsy-confirmed Pneumocystis carinii pneumonia at 3 different hospitals in Los Angeles, California" of which "[t]wo of the patients died" by the ...
It includes the single order Pneumocystidales, which contains the single monotypic family Pneumocystidaceae, which in turn contains the genus Pneumocystis, causative agent of Pneumocystis pneumonia. References
Pneumonia is a common respiratory infection, [2] affecting approximately 450 million people a year and occurring in all parts of the world. [3] It is a major cause of death among all age groups, resulting in 1.4 million deaths in 2010 (7% of the world's yearly total) and 3.0 million deaths in 2016 (the 4th leading cause of death in the world).
The AIDS epidemic, caused by HIV (Human Immunodeficiency Virus), found its way to the United States between the 1970s and 1980s, [2] but was first noticed after doctors discovered clusters of Kaposi's sarcoma and pneumocystis pneumonia in homosexual men in Los Angeles, New York City, and San Francisco in 1981.
In 1976, the name "Pneumocystis jiroveci" was proposed for the first time, to distinguish the organism found in humans from variants of Pneumocystis in other animals. The organism was named thus in honor of Czech parasitologist Otto Jirovec, who described Pneumocystis pneumonia in humans in 1952. After DNA analysis showed significant ...
Prevalence has trended somewhat downward since 2015. [2] The mortality of pneumoconiosis patients remained at a high level in recent years, with over 21,000 deaths each year since 2015. [ 2 ] It is likely that pneumoconiosis is under-diagnosed and under-reported, especially in countries without highly developed healthcare systems.
