Asbestos and tuberculosis in Trieste, Italy.

The distribution of counts of asbestos bodies in lung specimens from 25 persons dying of fibrocaseous tuberculosis was essentially identical to that in age- and sex-matched control subjects. Although tuberculosis mortality has been elevated in the past in cohorts of asbestos workers, asbestos exposure at environmental levels found in a region with a history of heavy asbestos use appears to be unassociated with risk of tuberculosis. Potentiation of the risk of death from tuberculosis may require both a high risk of tuberculosis in the general community and intense personal exposure to asbestos.

[Uterine metastases of extragenital carcinomas].

Metastasis to the uterus from distant primary neoplasms are rare: this report is an analysis of 20 cases. The primary tumors arose in the breast (12 cases), pancreas (3 cases), stomach (2 cases), lung (2 cases) and gallbladder (1 case). The corpus uteri (and namely the myometrium) is more often involved than cervix. The mean age of the patients is 71 years (range 42-84). Metastases caused abnormal uterine bleeding in only 2 cases; in the others cases no symptoms were observed and so they were unexpected autopsy findings.

Cancer of the endometrium in the province of Trieste: epidemiological considerations.

The Authors examined the epidemiological behaviour of endometrial carcinoma in the Province of Trieste from 1969 to 1980. In this period a European standard incidence of 14.33(0)/0000 was recorded. The most affected age group is 60 to 69, and the average age is 64 years. A clear increasing trend of this kind of neoplasia was recorded. This increase mainly occurs in younger age groups than those which presently are most affected.

Invasive cancer of the uterine cervix in the Province of Trieste: epidemiological considerations.

The epidemiological behaviour of the invasive cancer of the uterine cervix in the Province of Trieste is analysed. During this study period, 488 cases of this neoplasia were diagnosed with an incidence rate standardized for the European population of 20.25 degrees/0000. This value is within the average ones recorded in other geographic regions. The age group which is most affected is that from 60 to 64 years. By analyzing the overall incidence rate of the first two years if compared with the last two years of our study period, a 29% decrease is recorded, with an annual average decrease of 2.6%. This value is one of the highest reported in the literature. This decrease is recorded in the age groups over 40, while no decrease is recorded in women under age 40.

[Renal echography in diabetes mellitus].

The US findings in the kidneys of diabetic patients were studied. Diabetic subjects without clinical or laboratory signs of nephropathy were investigated by means of US in order to detect early anatomical lesions predictive of renal injury. The kidneys of cadaver diabetics were also studied to correlate US and histologic patterns. US alterations were observed in half of the cases: they were diffuse in 9% of cases and focal in 39%--hyperechoic spots and hyperechoic juxta-medulla. Focal spots are more common in juvenile-onset diabetics and they are correlated with the age of diabetes. At histology the above US patterns were correlated with the vascular wall alterations typical of diabetic nephropathy. Diffuse alterations are not specific. The authors conclude by suggesting US as a prognostic test for diabetic nephropathy.

[Ovarian metastases of extragenital tumors. Anatomo-pathological contribution to their interpretation].

Ovarian metastases from extragenital malignant tumours. An anatomohistopathologic approach. 102 cases of ovarian metastases from extragenital malignant non hematopoietic primaries have been studied in the Institute of Anatomy and Histopathology of the Trieste University. Breast cancers, followed by colonic, gastric and pancreatic tumours are the most frequent spreading primaries to the ovaries. Generally speaking the ovarian metastases seems to be closely related to the lower age at the tumour onset and to the width of metastatic spreading; this is true mainly for breast and colorectal cancer. These features should suggest that tumour aggressiveness, rather than some tropism of malignant cells, could play the most important role in the metastatic involvement of ovaries. A double behaviour should be instead suggested for gastric cancer: the first one is consistent with those previously described for the other tumours, the second one is related to a less aggressive gastric cancer, arising in the elderly (mean age 73 years old) with isolated involvement of the ovary showing the features of Krukenberg tumours.

[Metastasis from one tumor to another].

Tumour in tumour metastasis. The occurrence of more than one primary tumour in the same person is uncommon, nevertheless metastasis of one tumour to another is an extraordinary event. The malignant tumour usually metastasizes in a benign tumour, however a metastatic deposit within a malignant tumour is described. In the present study the literature is briefly reviewed and 43 new cases are described: in 38 the host neoplasm is a benign one, and in 4 is a malignant tumour. In the last case the metastases are present both in a malignant and in a benign tumor.

[The role of the absolute value and "density" of the prostate-specific antigen estimated echographically in the selection of patients to undergo a biopsy in suspected prostatic carcinoma. A comparison between PSA, palpation and echography in 95 patients undergoing echo-guided endorectal prostatic biopsy].

We retrospectively reviewed the findings relative to 95 patients with known prostate specific antigen (PSA) values who had undergone digital rectal examination, transrectal US and US-guided biopsy for suspected prostate carcinoma. Histology (48 adenocarcinomas, 26 BPHs, 12 inflammations and 9 negatives) was compared with results from rectal examination, prostate US, PSA values and "density" (PSA/prostatic volume, as measured with US). PSA values < 4 ng/ml exhibited 90% negative predictive value and PSA > 10 ng/ml 70.8% positive predictive value. In the intermediate range (4-9.9 ng/ml) the positive predictive value of PSA was 44.4% and its negative predictive value was 55.5%. PSA density did not affect predictive values in the two groups with PSA < 4 and > 10 ng/ml, while in the intermediate 4-9.9 ng/ml group, positive predictive value raised to 62.5% and negative predictive value to 81.8%, thus increasing the specificity of PSA values and US findings. Our results suggest that PSA should be the examination of choice in the patients with prostatic disease. Follow-up with PSA dosage after one year may be suggested when PSA < 4 ng/ml. PSA density can be helpful in patients with PSA values ranging 4-9.9 ng/ml; biopsy should be performed when the index > 0.15, while follow-up at 6 months should be performed when the index < 0.15. PSA values > 10 ng/ml require further evaluation with rectal examinations, prostate US and US-guided biopsy. Random biopsies are suggested when PSA values are > 20 ng/ml.
