We report an educational autopsy case of combined pulmonary fibrosis and emphysema. Radiological patterns of the upper lung were considered as mostly emphysema, but pathological observation revealed significant interstitial fibrosis of usual interstitial pneumonia as a major pathology. The patient eventually developed acute exacerbation of background interstitial pneumonia. Careful radiological...

Idiopathic interstitial pneumonia is a heterogeneous group of diseases. Recently, the importance of a detailed differentiation of nonspecific interstitial pneumonia from other idiopathic interstitial pneumonias has been demonstrated. Most critical appeared to be a proper classification based on clinical presentation, high-resolution CT findings, bronchoalveolar lavage fluid cell findings, and h...

During the oxidation of silicon, interstitials are generated at the oxidizing surface and diffuse into the silicon. Boron diffusion was used to map the local interstitial super-saturation, the ratio of interstitial concentration to the equilibrium concentration of interstitials I/I, versus depth above buried Si0.795Ge0.2C0.005 layers during oxidation. The average interstitial supersaturation at...

The testes of 18 foetal sheep, of crown-rump length from 2-8 to 40 cm, have been studied by the PAS, Sudan black, and plasmal tests. Typical interstitial cells differentiate from mesenchymal precursors; the nucleus alters first, becoming ovoid and vesicular; then the cytoplasm increases in amount, its processes become fewer and smaller, sudanophil lipid droplets appear, and the result is a lipi...

The individual processes involved in interstitial fluid volume and protein regulation (microvascular filtration, lymphatic return, and interstitial storage) are relatively simple, yet their interaction is exceedingly complex. There is a notable lack of a first-order, algebraic formula that relates interstitial fluid pressure and protein to critical parameters commonly used to characterize the m...

The nature of the much debated valence state of an interstitial oxygen atom in oxygen-doped La2CuO4 is the subject of this paper. In model cluster calculations, we studied the position, charge, and spin state of the interstitial oxygen atoms in this superconductor. The models considered allow the interstitial oxygen to move off a symmetrical position, to have varying spin and charge, and to be ...

BACKGROUND Cigarette smoking is associated with emphysema and radiographic interstitial lung abnormalities. The degree to which interstitial lung abnormalities are associated with reduced total lung capacity and the extent of emphysema is not known. METHODS We looked for interstitial lung abnormalities in 2416 (96%) of 2508 high-resolution computed tomographic (HRCT) scans of the lung obtaine...

This is the first Australian study to examine survival and clinical characteristics in biopsy-proven idiopathic interstitial pneumonia. A cohort of 70 patients from a single institution between January 1990 and December 1999 was reviewed. All patients were Caucasian, 23 (33%) female. Mean age+/-SD at diagnosis was 60+/-12 yrs for males and 54+/-14 yrs for females. A total 24% of patients had ne...

BACKGROUND Endometriosis and interstitial cystitis/painful bladder syndrome share similar symptoms. Interstitial cystitis was once considered rare, but it is now recognized as more common than previously thought. This review examines evidence that patients presenting with symptoms typically attributed to endometriosis or with unresolved pelvic pain after treatment for endometriosis may, in fact...
