background: in many cases of ild (interstitial lung disease), overlap diagnosis is considered. here, a few cases with diagnosis of a variety of ilds, where eventual open lung biopsy has been performed are selected. reference will be made to reliable sources to show that nsip can still be a variant of uip (usual interstitial pneumonia) with better treatment response and prognosis. case presentat...

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...

According to the American Thoracic Society (ATS)/European Respiratory Society consensus classification, idiopathic interstitial pneumonias (IIPs) include several clinic-radiologic-pathologic entities: idiopathic pulmonary fibrosis (IPF), usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), cryptogenic organizing pneumonia, acute interstitial pneumonia, respiratory bron...

Pneumoconioses are a group of non-neoplastic pulmonary disorders caused by inhaled inorganic particles. Welldescribed forms of pneumoconiosis include those from asbestos, silica, coal dust, beryllium, and hard metals. Giant-cell interstitial pneumonia is an uncommon pneumoconiosis, usually due to exposure to hard-metal compounds, primarily cobalt and tungsten carbide. The natural course of the ...

IdIopAthIc InterstItIAl pneumonIAs The terminology of idiopathic interstitial pneumonias (IIP) varies from country to country and is often confusing. It is called idiopathic pulmonary fibrosis (IPF) in the United States,7 cryptogenic fibrosing alveolitis (CFA) in the United Kingdom8 or idiopathic interstitial pneumonia in Japan.9 In our country, it is termed either as IPF or CFA. The landmark c...

Idiopathic interstitial pneumonias are currently classified into four categories: usual interstitial pneumonia, nonspecific interstitial pneumonia with fibrosis, acute interstitial pneumonia and desquamative interstitial pneumonia. The fibrotic process in interstitial pneumonias appears to result from a complex interaction between fibroblasts, other lung parenchymal cells and macrophages. The c...

Exercise-induced hypoxia is an index of the severity of interstitial lung disease. We hypothesized that desaturation during a 6-minute walk test would predict mortality for patients with usual interstitial pneumonia (n = 83) and nonspecific interstitial pneumonia (n = 22). Consecutive patients with biopsy-proven disease performed a 6-minute walk test between January 1996 and December 2001. Desa...

Pulmonary eosinophilia comprises a heterogeneous group of diseases that are defined by eosinophilia in pulmonary infiltrates or in tissue. Drugs can cause almost all histopathologic patterns of interstitial pneumonias, such as cellular and fibrotic nonspecific interstitial pneumonia, pulmonary infiltrates and eosinophilia, organizing pneumonia, lymphocytic interstitial pneumonia, desquamative i...

i n a survey of pneumonia due to mycoplasma 282 out of 12168 ovine and caprine lung condemnation were collected (2.32%). mycoplasma spp. has been isolated from pneumonic cases in 4 sheep and 2 goats. pcr studies were confirmed the genus of mycoplasma although attempting for identification of strains m. mycoides, m. capricolum/caprine pleuropneumonia and m. arginin were in failure. the lesions i...

OBJECTIVE To make a retrospective analysis of lung biopsy samples obtained from patients diagnosed with chronic idiopathic interstitial pneumonia, as defined in the American Thoracic Society/European Respiratory Society classification system made public in 2000. METHODS Samples from 252 open-lung biopsies of patients with interstitial lung disease, all performed between 1977 and 1999, were re...
