Positive FDG-PET/CT of the pleura twenty years after talc pleurodesis: three cases of benign talcoma
…This inflammatory reaction could decrease with time, as in other inflammatory processes. Since talc is not metabolized by the body, the FDG-PET scan can remain positive, most likely because of a foreign-body granulomatous reaction…

Acute phase response, inflammation and metabolic syndrome biomarkers of Libby asbestos exposure
…exposure route. One day after a single LA dose, two 'acute phase' proteins, part of a general reaction to inflammation, rose in all three strains tested. Lipocalin-2 also rose in those three strains, but osteopontin…

Generation of hydroxyl radical by crocidolite asbestos is proportional to surface [Fe3+]
…in concentrations varying from 0 to 250 mM. Inclusion of deferoxamine in the reaction mixture provided similar results of diminishing both TBA reactive products and dihydroxybenzoic acid generation. We conclude that oxidant generation by crocidolite is…

Tissue response to intraperitoneal asbestos with preliminary report of acute toxicity of heart-treated asbestos in mice
…plaques and invasive granulomas, while none of 12 talc mice did. The authors described the reaction as histologically similar to mesothelioma but obtained no morphologic evidence of actual malignancy. In a second experiment, asbestos heated to…

Adenomatoid tumor of ejaculatory duct
…stain for two prostate markers, prostate specific antigen and prostate specific acid phosphatase. It showed no reaction for factor VIII antigen. It contained faint focal mucin and some yellowish brown pigment. The authors separated it from…

Potassium octatitanate fibers (TISMO) induce pleural mesothelial cell reactions with iron accumulation in female A/J mice
…to assess responses. Only the fiber-shaped TISMO, morphologically similar to asbestos, induced a severe reaction of the pleura. A number of TISMO fibers were observed in the alveoli, indicating penetration through the pleura. Following Berlin…

Malignant mesothelioma and CEA staining
…which is neither tumor- nor organ-specific. The author added that CEA staining results are not valid unless this reaction is first removed by absorbing the antisera with NCA. Earlier reports describing CEA in mesothelioma had…

Gallium scanning in differentiating malignant from benign asbestos-related pleural disease
…no history of exposure. Scans were also positive in 3 of the 16 patients with benign disease (19%), and tissue removed from these three showed a strong inflammatory reaction. Among asbestos-exposed patients, the scan's…

Immune adherence reactivity of rat alveolar macrophages following inhalation of crocidolite asbestos
…a statistically significant difference. Sheep red cells, which cannot take part in this reaction, stuck far less to macrophages from exposed rats. Treating the cells with antiserum against the complement component C3 reduced adherence to 4…

Diffuse intrapulmonary malignant mesothelioma masquerading as interstitial lung disease: a distinctive variant of mesothelioma
…micropapillary, and solid patterns. Initial diagnoses by referring pathologists included reactive changes (1), hypersensitivity pneumonitis versus drug reaction (1), desquamative interstitial pneumonia versus neoplasm (1), and mesothelioma (2). Microscopic pleural involvement was identified in 4 cases…

New roads open up for implementing immunotherapy in mesothelioma
…were seen. Another was their own group's dendritic-cell vaccine trial, which was well tolerated and induced an immune reaction. They also described mouse experiments with drugs such as celecoxib and zoledronic acid. The authors…

Antemortem diagnosis in two cases of malignant peritoneal mesothelioma
…the abdomen. A biopsy taken by peritoneoscopy, a scope inserted into the abdomen, was read as consistent with mesothelioma or an inflammatory reaction. The Armed Forces Institute of Pathology then confirmed mesothelioma. He died, and autopsy…

Pathologic changes in the small airways of the guinea pig after amosite asbestos exposure
… where these fibers penetrated the airway walls, an interstitial inflammatory and fibrotic reaction (asbestosis) occurred. It is concluded that 1) amosite asbestos produces diffuse abnormalities throughout the noncartilagenous airways and possibly the cartilagenous airways as well…

Activation of UICC crocidolite: the effect of conversion of some ferric ions to ferrous ions
…The amount of iron in asbestos fibers, its oxidation state, and its availability to specific chelating agents determine their ability to catalyze the aforementioned reactions. In the present study, the activation of UICC crocidolite was achieved…
