Abstract
This report concerns the pathologic findings observed at autopsy in a 10-year-old heterotopic heart transplant under cyclosporine treatment. The allograft showed a diffuse multivessel atherosclerotic disease whereas in the recipient heart coronary arteries and aorta were focally affected by atherosclerosis. The proliferating cell nuclear antigen had significantly increased expression in the allograft vessels in comparison with the recipient.

Abstract
A case-control study was carried out on 145 male lung-cancer patients diagnosed at autopsy and 178 controls, in order to investigate the relationship between asbestos exposure and the cell type of pulmonary carcinoma. Adenocarcinomas (AD) were individually matched with other cell types and with controls. The relative risk (RR) of developing AD in relation with lung asbestos body (AB) content as the exposure indicator was calculated by using logistic-regression analysis for matched sets. Two cutoff levels, 1,000 and 10,000 asbestos bodies per gram dry weight (AB/gdw), were used in the analysis. In addition, AB counts were treated as a continuous variable (log AB+I). A significant association was found between AD and asbestos exposure, using levels and logarithmic transformation. However, an association of asbestos exposure with cell types other than AD could not be ruled out.

Abstract
We describe a case of malignant peritoneal mesothelioma arising in a 17-year-old boy. The diagnosis was based on a comprehensive study including light microscopy, histochemistry, immunohistochemistry, evaluation of the clinical course, and autopsy examination. Analytical transmission electron microscopy showed a concentration of 510,000 asbestos fibers/g dry lung tissue. The fibers were represented by chrysotile (62%) and tremolite (38%) asbestos. About 40% of the total fibers were longer than 5 microns. The presence of tremolite fibers was probably due to environmental exposure to contaminated cosmetic talc. This is the first reported case of pathologically proven exposure to asbestos dust in malignant mesothelioma of childhood and adolescence.

Abstract
A case of malignant peritoneal mesothelioma mimicking mesenteric inflammatory disease (MID) is presented. The patient had mesenteric and omental lesions characterized at biopsy by extensive fibrosis of fat tissue with mild to moderate inflammation. One year later, post-mortem examination revealed a well-differentiated epithelial mesothelioma. Immunohistochemical stains for keratin and vimentin were diffusely positive, whereas EMA showed a membranous staining of scattered cells. CEA, Ber-EP4, B72.3 and Leu-M1 were negative. In addition, actin monoclonals decorated groups of cells pertaining to the tumoural component. Immunostains of sections from retrieved paraffin blocks of the previous biopsy showed that the bulk of the spindle-shaped and histiocytic-like cells present in the fibrous streams was strongly labeled by low-molecular-weight keratin, and coexpressed vimentin and actin. EMA showed a membranous staining of sporadic spindle and round cells. The other immunostains were invariably negative. This immunohistochemical pattern closely corresponded to the immunophenotype of the mesothelial tumour detected at autopsy and was very suggestive of myofibroblastic/submesothelial cell origin. The quantitative evaluation of silver nucleolar organizer regions (Ag-NORs) demonstrated high levels of cell proliferation in both surgical and autopsy tissue samples.

Abstract
A case of pneumoconiosis with unknown occupational history was examined both pathologically and mineralogically by means of a variety of techniques, including analytical scanning and transmission electron microscopy with electron diffraction and energy dispersive x-ray analysis, and electron resonance spectroscopy. The pathologic features consisted of a diffuse interstitial fibrosis with deposits of amorphous and crystalline particles and granulomatous reaction. The identification of minerals, mainly talc, halloysite, coal and chlorite, allowed a definite diagnosis of mixed silicate pneumoconiosis to be made. This is an example of complete pathologic, mineralogic and physico-chemical analysis of a case of pneumoconiosis.

Abstract
Nine hundred twenty-five unselected autopsies were investigated for the presence or absence of hyaline peritoneal (splenic or hepatic) plaques, hyaline pleural plaques, asbestos, liver cirrhosis, heart failure, previous peritoneal dialysis or abdominal surgery, chronic peritonitis, splenomegaly, splenic infarcts, and pulmonary or abdominal tuberculosis. Lung asbestos body concentrations were calculated in 570 subjects. Peritoneal plaques were recorded in 163 cases. In both univariate and multivariate analyses, they were associated with cirrhosis, pulmonary nonactive tuberculosis, pleural plaques, and asbestosis. Association with asbestos body counts was also found, with a significant trend. Peritoneal plaques were described long ago in different pathologic conditions, for some of which (cirrhosis and nonactive pulmonary tuberculosis) the association is confirmed by the present analysis. It is suggested that they are significantly associated, moreover, with indicators of asbestos exposure.

Abstract
OBJECTIVE The association between involuntary smoking and lung cancer has been supported by most epidemiologic studies, but a number of authors and interest groups claim that the possibility of bias has not been excluded. Few autopsy-based studies have explored the role of active smoking and other exposures in lung carcinogenesis, and none has been previously done to examine the role of passive smoking. We have undertaken such an autopsy-based study in Athens, Greece. DESIGN Lung specimens were taken at autopsy from 400 persons 35 years of age or older, of both genders, who had died within 4 hours from a cause other than respiratory or cancer in Athens or the surrounding area. For each person at least seven tissue blocks were taken from the main and lobar bronchi and at least five blocks from the parenchyma, including an average of about 20 smaller cartilaginous bronchi and membranous bronchioles. The specimens were examined without knowledge of the exposures of the particular subject in Turin, Italy. For 283 (71%) of the subjects the preservation of the bronchial epithelium was satisfactory for pathological examination, and for 206 among them (73%) an interview could be arranged with their next of kin, focusing on smoking habits of the deceased and their spouses, as well as other variables. The interviewers were not aware of the results of the pathological examinations. MAIN OUTCOME MEASURE Specimens were examined for basal cell hyperplasia, squamous cell metaplasia, cell atypia, and (in membranous bronchioles and bronchiolo-alveolar airways) mucous cell metaplasia, ie, pathological entities that may be lung cancer risk indicators or epithelial, possibly precancerous, lesions (EPPL). The gland and wall thicknesses were also measured and their ratio calculated (Reid Index). RESULTS In comparison with nonsmokers, EPPL values were significantly higher among current smokers and higher, but not significantly so, among former smokers. Furthermore, EPPL values were significantly higher among deceased nonsmoking women married to smokers rather than to nonsmokers. In this set of data neither occupation nor residence was associated with EPPL, but this could be due to the poor correlation of residential history with exposure to air pollution and the lack of adequate standardization of contemporary Greek occupations. The Reid Index was higher among smokers and former smokers in comparison with nonsmokers, among subjects with mainly urban residence in comparison with those with mainly rural residence, and among nonsmoking women married to smokers in comparison with those married to nonsmokers, but none of these differences was statistically significant. CONCLUSION These results provide support to the body of evidence linking passive smoking to lung cancer, even though they are based on a study methodologically different from those that have previously examined this association.

Abstract
The effects of interferon therapy on liver histologic findings were assessed in a randomized controlled trial consisting of 80 patients with chronic non-A,non-B hepatitis. Twenty-eight patients received 1 million units of recombinant interferon alpha-2b; 25 patients received 3 million units, subcutaneously, three times a week for 24 weeks; and 21 patients were observed as untreated controls; all of them underwent liver biopsy within 6 months from the beginning of the study and on the last day of therapy. Six patients were withdrawn from the study because of inadequate liver biopsy specimens. Alanine aminotransferase levels were determined before, during, and after therapy. For each biopsy, a semiquantitative score of histologic features, the histologic activity index, and the overall histologic assessment were performed. Ninety-five percent of patients tested positive for hepatitis C virus antibody. Portal inflammation, piecemeal and spotty necrosis, and bile duct proliferation were significantly decreased in patients with normalized alanine aminotransferase. The effectiveness of therapy was dose dependent: piecemeal and spotty necrosis and the histologic activity index showed a significant decrease only in 3-million-unit-treated patients. Hepatocellular degeneration and fibrosis did not change significantly after treatment.

Abstract
Detailed contents and aims of an educational intervention for diabetic foot are presented, together with evaluation tools and results at 3, 6 and 12 month interval after the course. Knowledge level and "health" of the foot were assessed at 12 month interval on 2/3 of the 100 diabetic patients originally exposed to the educational intervention. After 12 months 80% of patients showed a good retention of knowledge on practical issues related to foot care, while 77% of patients with persistent foot problems were not independent (because of hypo-mobility or sight problems) in foot care.

Abstract
We have investigated the growth-factor-like activity of a approximately 200-kDa, IP 8.3, cytoplasmic glycoprotein, the expression of which appears to be restricted to normal and malignant human mesothelium. This substance stimulated the growth of human mesothelioma cell cultures at greater rates than did foetal calf serum, but it failed to induce proliferation of lung carcinoma cell cultures. In addition, we have tried to trace the biosynthetic pathway of this mitogenic factor in normal human mesothelial cells by means of immuno-electron microscopy with a polyclonal antibody directed against this molecule. Positive immunogold labelling was found in the lumina of the cisternae of the endoplasmic reticulum, to a lesser extent on the outer surface of the plasma membrane, and also in structures corresponding to the coated pits. These ultrastructural findings are consistent with the hypothesis of the glycosylation of the newly synthesized protein in the endoplasmic reticulum and the subsequent uptake of the secreted molecule, which accumulates in the coated pits before internalization. The results suggest that this mitogenic glycoprotein could play a role in an autocrine growth control mechanism influencing mesothelial cell proliferation.

Abstract
The pathogenesis of diabetic nephropathy remains elusive. A role for renal prostaglandins in antagonizing the hormonal effects of renin-angiotensin II has been postulated as a putative factor leading to hyperfiltration in patients with Type 1 (insulin-dependent) diabetes mellitus. Our aim was to elucidate the effects of angiotensin II on kidney haemodynamics and on blood pressure in eight normal subjects, in nine normotensive, in nine hypertensive with normal sodium-lithium countertransport activity in erythrocytes, in seven hypertensive without and in eight hypertensive Type 1 diabetic patients with microalbuminuria and with high sodium-lithium countertransport activity in erythrocytes. Angiotensin II infusion (4 ng.kg-1.min-1 for 60 min) decreased the glomerular filtration rate to a greater extent in normal subjects (-20%), than in normotensive patients (-5% p less than 0.01), in hypertensive patients with normal sodium-lithium countertransport activity in erythrocytes (-8% p less than 0.01) in hypertensive patients with high sodium-lithium countertransport (-6% p less than 0.01) and in hypertensive microalbuminuric patients (-5% p less than 0.01) with Type 1 diabetes. The urinary excretion rate of vasodilatory prostaglandins was two-three fold higher in all patients than in normal subjects. Acute indomethacin treatment restored a normal response to angiotensin II infusion in normotensive patients, but did not change the renal haemodynamic response in normal subjects. With regard to hypertensive patients with and without microalbuminuria indomethacin treatment restored a normal response to angiotensin II in some but not all patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A case-control study was carried out on 41 surgical and 106 autopsy histological tissue samples of lung cancer in men, in order to investigate the relationships between asbestos exposure and cell type of pulmonary carcinoma. Both occupational history (obtained by interviews of surgical patients or of the next-of-kin for deceased subjects) and lung asbestos body content (determined by optical count after hypochlorite digestion and membrane filtration of lung tissues) were considered as asbestos exposure indicators. No significant relationships were found in the surgical series after adjustment for smoking. The autopsy series showed a trend towards an association between lung adenocarcinoma and asbestos exposure indicators and a markedly higher agreement between the 2 kinds of indicators than that observed in the surgical series.

Abstract
We describe a case of sarcomatous tumor of the chest wall with differentiation toward bone and cartilage that was observed in an asbestos-exposed worker. Although the mesothelial nature of the tumor was at first considered, it was not proven. Later, the tumor was shown to be a mesothelioma using a panel of pertinent antibodies that included a recently described anti-mesothelial cell marker. In addition, asbestos bodies were found in association with the sarcoma cells. Our findings indicate that whenever physicians encounter any type of primary sarcomatoid tumor involving serous membranes, the possibility of malignant mesothelioma should be regarded a priori.

Abstract
A group of 199 autopsy subjects was investigated for minimal pathologic pulmonary changes possibly resulting from asbestos exposure. According to the standards proposed by the Pneumoconiosis Committee of the College of American Pathologists, features consistent with asbestosis grade 1 (AG1) include findings of bilateral pleural plaques, high concentrations of asbestos bodies (ABs) in digested lung tissue, and a history of occupational risk. Similar changes without evidence of ABs on histologic section and referred to as small airway lesions (SALs) present a less well-correlated association. In this study, SALs showed significant differences when compared with the features observed in subjects without possible asbestos-related pulmonary fibrotic changes. Minimal bronchioloalveolar fibrotic changes with concomitant presence of ABs can be considered a mild pneumoconiotic lesion (AG1), and SALs may be regarded as an additional indicator of asbestos exposure.

Abstract
A screening procedure to select, in autopsy populations, subjects having a major likelihood of previous occupational exposure to asbestos is described. To test our necropsy population we searched for pleural plaques (PPs); the optical count of both lung asbestos bodies (ABs) and uncoated mineral fibers (UMFs) at least 10 microns in length was recorded. In the adult autopsy population studied in the Turin area, the predictive value given by a positive test for large-size PPs (mostly bilateral) was about 55%. This level of probability did not rise in relation to the AB counts, whereas an increase to over 75% was observed if more than 10,000 UMFs/g dry lung were present. In subjects without PPs or with small-size plaque lesions (mostly unilateral), predictive values of positive tests were 20 to 30% when ABs and UMFs were found to be below 100 and 10,000/g, respectively, and increased to approximately 40% if the AB count exceeded 500/g and to almost 70% for an UMF count above 100,000/g. In subjects without PPs or with small-size plaque lesions, the probability of being nonexposed was greater than 90% if neither ABs nor UMFs were found. This autopsy screening may be a reliable tool in selecting cases most probably related to occupational exposure.
