BACKGROUND Interstitial pneumonias (IP) cover a broad spectrum of diseases. Open lung biopsies reveal histological patterns and suggest possible diagnoses. Complete clinical records are necessary for final diagnoses. Especially idiopathic interstitial pneumonias (IIP) according to the ATS/ERS classification can only be diagnosed under these predictions. The aim of this study was to compare the ...

Idiopathic interstitial pneumonias comprise approximately one-third of interstitial lung diseases (also called diffuse parenchymal infiltrative lung diseases). The classification of idiopathic interstitial pneumonias has undergone several revisions since the initial description of 40 years ago, and the most recent version was published in 2013. Although some aspects have been clarified, this gr...

In order to compare the etiology, clinical manifestations, and prognosis of patients acquiring nosocomial pneumonia, we studied and compared sixty normal hosts who acquired nosocomial pneumonia during Jan 1, 1989-Dec 31, 1991 (group I) with seventy-two immunocompromised patients with nosocomial pneumonia who were admitted during 1984-1992 (group II). Both groups were similar in some patterns, e...

The idiopathic interstitial pneumonias are diffuse lung diseases characterized by interstitial inflammation and fibrosis. High resolution computed tomography (HRCT) is the best imaging technique for the study of interstitial disease. The general term "idiopathic interstitial pneumonia" includes usual interstitial pneumonia/idiopathic pulmonary fibrosis, nonspecific interstitial pneumonia, desqu...
