A large cohort of petroleum refinery workers with long duration of employment, long latency, and relatively young age at hire had its vital status updated through Dec. 31, 1980. The standardized mortality ratio (SMR) for all causes was 78. Each nonneoplastic cause had an SMR below 100, including SMRs of 63 for emphysema and for all diseases of the genitourinary system and of 73 for chronic nephritis. The SMR for all cancers was 87. SMRs for specific neoplasms included digestive system, 90; lung, 85; kidney, 68; brain, 89; leukemia, 101; multiple myeloma, 123; unspecified lymphoma, 112; polycythemia vera (four deaths), 455; myelofibrosis (three deaths), 201; and benign and unspecified brain neoplasms, 108. There were nine deaths from mesothelioma; all nine employees had more than 20 years of employment, with an SMR of 241.

A proportionate mortality ratio (PMR) study was undertaken of 7,121 members and retirees of the United Association of Plumbers and Pipefitters in California who died in 1960-79. The PMR for all malignant neoplasms was 1.24, with a major contribution from lung cancers (PMR = 1.41). Lung cancer PMRs were consistently elevated, through the 20-year study period, across the pipe trades and within different birth cohorts. Sixteen mesothelioma deaths occurred, suggesting asbestos as a risk factor. PMRs for malignancies of the stomach, kidney, brain, and lymphopoietic system were also elevated, especially among plumbers. Chronic rheumatic heart disease, emphysema, liver cirrhosis, and all external causes of death were the major non-cancer causes with significantly elevated PMRs. There were significant deficits in diabetes mellitus, all pneumonia, chronic nephritis, and vascular lesions of the central nervous system (CNS). PMRs for successive birth cohorts among all study subjects revealed decreasing emphysema risk, suggesting previous reduction of a risk factor for this disease. Among plumbers, PMRs for death due to several non-respiratory malignancies showed an increasing trend with recency of birth cohort.

A cohort of 3971 white miners in South Africa, born between 1 January 1916 and 31 December 1930 who were alive on 1 January 1970 and currently working in the East Rand-Central Rand-West Rand mining areas, was followed up for nine years, when the 3426 survivors were aged from 48 to 62. Fifteen (0.4%) had been lost to view and 530 had died (13.4% of the 3956 whose vital status was determined). Based on the occupational histories of a 30% sample of the cohort it was known that the vast majority were gold miners. An estimated 93% had worked more than 85% of their mining service in gold mines. Standardised mortality ratios were calculated as the ratios of the deaths observed in the cohort to those expected on the basis of concurrent mortality in the reference population--the total white male population in the Republic of South Africa. There was little sign of a "healthy worker effect"; of several possible reasons, one is that the white miner in South Africa had adopted certain unhealthy life styles, another is that the reference population was otherwise inappropriate. The SMR for all causes of death (117.6) was raised because of excess mortality due to the following causes: lung cancer (161.2), chronic respiratory diseases (165.6), and acute and chronic nephritis (381.0). A case-referent analysis was carried out on those miners in the cohort who had spent at least 85% of their service in gold mines. For lung cancer, smoking was the main contributory factor towards disease. For chronic respiratory diseases bronchitis, emphysema, asthma, pneumoconiosis, and pulmonary heart disease), smoking was also the main risk factor, but there was an association wih cumulative dust exposure. Raised blood pressure, smoking, and adiposity were associated with ischaemic heart disease as was the duration of service underground. Study of comprehensive medical histories in all 530 deaths, including necropsy in most cases, showed that none was directly due to pneumoconiosis or to tuberculosis.

Deaths due to prostatic cancer, renal cancer, bronchitis or emphysema, and nephritis or nephrosis in three cohorts of cadmium workers have been investigated in a case-control study. Evidence of an association of risk for these diseases with intensity and duration of exposure to cadmium was sought. The only clearly statistically significant finding was of an association of deaths coded as bronchitis or emphysema with "high" levels of exposure to cadmium fume, which was related also to duration of exposure. There was suggestive evidence also (p congruent to 0.10) of an increased risk for nephritis or nephrosis after high exposure. Marginally increased risks were observed for prostatic cancer after high or "medium" exposure, but these were not statistically significant.

The association between deficiency of alpha-1-antitrypsin (A1AT) and glomerulonephritis has been only sporadically reported on, as opposed to the linkage between A1AT-deficiency and lung emphysema or hepatic cirrhosis. We describe the case of a 30-year-old man with A1AT deficiency who developed hepatic cirrhosis in early childhood, and IgA glomerulonephritis and hypertension in adult life. The IgA nephritis followed an unusual course. After three years of slight elevation of serum creatinine levels, the patient rapidly developed renal failure necessitating acute hemodialysis. The deterioration of the renal function was preceded by eruption of skin lesions, believed to represent a vasculitis. After six months of hemodialysis, the patient successfully received a transplanted kidney from his mother. The literature is reviewed with respect to the association between A1AT-deficiency and renal disease. We discuss possible underlying causes for the rapid deterioration of renal function in this patient.

To place previously recognized mortality risks into the context of the total mortality from all causes, an updated retrospective cohort mortality study was conducted on 3,238 white males from the US Public Health Service cohort of Colorado Plateau uranium miners. Vital status was followed from 1960 through 1990. Life-table analyses used combined New Mexico, Arizona, Utah, and Colorado mortality rates for external comparison and mortality risks within the lowest radon-exposure or duration-employed category for internal comparison. Significantly elevated SMRs were found for pneumoconioses (SMR = 24.1, 95% CI 16.0-33.7), lung cancer (SMR = 5.8, 95% CI 5.2-6.4), tuberculosis (SMR = 3.7, 95% CI 1.9-6.2), chronic obstructive respiratory diseases (SMR = 2.8, 95% CI 2.2-3.5), emphysema (SMR = 2.5, 95% CI 1.9-3.2), benign and unspecified tumors (SMR = 2.4, 95% CI 1.0-4.6), and diseases of the blood and blood-forming organs (SMR = 2.4, 95% CI 1.0-5.0). No significantly lowered SMRs were found for any disease. For lung cancer and pneumoconioses standardized rate ratios increased with increasing exposure to radon progeny or duration of employment. Most findings from this update are consistent with previous studies. Not observed were previously elevated SMRs for chronic nephritis and for acute alcoholism. New findings observed were elevated SMRs for benign and unspecified tumors and for diseases of the blood and blood-forming organs. The most important long-term mortality risks for the white uranium-miners continue to be lung cancer and pneumoconioses, for which SMRs remain significantly elevated after a mean period of 22.4 years since last uranium mining.

The association between alpha1-antitrypsin (A1AT) deficiency and glomerulonephritis has only sporadically been reported, and mostly based upon autopsy findings, as opposed to the more frequent linkage between A1AT deficiency and lung emphysema with or without hepatic cirrhosis. The present case report describes a 30-year-old man with A1AT deficiency, without evidence of lung disease, who developed hepatic cirrhosis in early childhood and IgA glomerulonephritis and hypertension in adult life. The IgA nephritis followed an unusual course, with a sudden deterioration of the renal function, possibly induced by uncontrolled hypertension or the possible occurrence of vasculitis. After 6 months of hemodialysis, the patient successfully underwent living-related-donor kidney transplantation.

A 21-year-old female with chronic membranoproliferative nephritis was admitted for suspected esophageal disruption and asthma after severe, prolonged vomiting. At the time of admission she presented with dyspnea, tachypnea, arterial hypotension and tachycardia. Physical examination showed discrete signs of ectopic air at the neck and distended cervical veins. CT-scan of the chest showed severe mediastinal emphysema with compression of the right atrium. After cervical mediastinotomy the cardiorespiratory parameters normalized immediately. Esophagoscopy showed multiple longitudinal mucosal tears between 25 and 45 cm; fluoroscopically, there was no leakage of contrast medium. Following conservative treatment the patient recovered completely and was discharged on day 8.

The most striking feature observed in this study is the extensive variation of the serum in relation to its proteins. It was found that in certain diseases the globulin fraction is markedly increased, whereas the total protein of the serum may be normal, or may fall far below normal in amount. The diseases in which an increase in the globulins takes place may be grouped as follows: (1) cardiac diseases associated with decompensation and serous effusions, (2) pulmonary or respiratory affections of inflammatory or non-inflammatory origin (pneumonia, emphysema, polycythemia), (3) diabetes mellitus, and (4) parenchymatous nephritis. In the serum of chronic parenchymatous nephritis the increase in the globulin content is most pronounced and may constitute nearly all the protein, or as much as 95 per cent. The globulin content of serum is normal or diminished in the following diseases: (1) simple achylia gastrica (short duration), (2) tuberculosis, (3) diabetes insipidus, and (4) chronic interstitial nephritis. Other ingredients of the sera analyzed showed variations which cannot be definitely classified; but in a general way it appears upon careful analysis that an accumulation of water and salt occurs in those diseases in which the globulin fraction of the blood serum is increased.

There is a trend to reduce the space allowance per animal in cattle feedlot, despite its potential negative impact on animal welfare. Aiming to evaluate the effects of space allowance per animal in outdoor feedlots on beef cattle welfare, a total of 1350 Nellore bulls (450 pure and 900 crossbred) were confined for 12 weeks using three space allowances: 6 (SA6), 12 (SA12) and 24 (SA24) m2/animal (n = 450 per treatment). Bulls were housed in three pens per treatment (n = 150 per pen). The first 6 weeks in the feedlot were defined as 'dry' and the last as 'rainy' period, according to the accumulated precipitation. Animal-based (body cleanliness, health indicators and maintenance behaviour) and environmental-based indicators (mud depth and air dust concentration) were assessed weekly during the feedlot period. Most of the health indicators (nasal and ocular discharge, hoof and locomotion alterations, diarrhoea, bloated rumen and breathing difficulty) were assessed in a subset of 15 animals randomly selected from each pen. Coughs and sneezes were counted in each pen. Maintenance behaviours (number of animals lying and attending the feed bunk) were recorded with scan sampling and instantaneous recording at 20-min intervals. Postmortem assessments were carried out in all animals by recording the frequencies of macroscopic signs of bronchitis, pulmonary emphysema, nephritis and urinary cyst and by measuring the weight and cortical and medullar areas of adrenal glands (n = 30 per pen). Compared with SA12 and SA24, SA6 showed a greater number of sneezes per minute during the dry period and a greater percentage of animals with locomotion alterations during the rainy period. Coughing, diarrhoea and nasal discharge affected a larger number of animals in the SA6 relative to the other two groups. During the rainy period, there was a lower percentage of animals with nasal and ocular discharge, and a greater percentage of animals with abnormal hoof and lying. A lower percentage of animals in SA6 and SA12 (but not SA24) attended the feed bunk during the rainy relative to the dry period. A mud depth score of 0 (no mud) was most frequent in SA24 pens, followed by SA12 and then SA6. Adrenal gland weight and cortical area were lower in SA24 animals compared with those in SA6 and SA12. The results show that decreasing the space allowance for beef cattle in outdoor feedlots degrades the feedlot environment and impoverishes animal welfare.
