Mortality in workers at a northwestern United States prebake-type aluminum reduction plant was examined in a historical prospective (cohort) study. Although the standardized mortality ratio (SMR) for all causes of death was low (86), lung cancer (SMR 117), pancreatic cancer (SMR 180), lymphatic and hematopoietic cancers (SMR 184), fatal benign tumors of the brain (SMR 391), and pulmonary emphysema (SMR 204) showed excess deaths. Analysis of mortality by job-exposure category, duration of employment and latency suggests that some of the lymphatic and hematopoietic cancers (especially malignant lymphoma), lung cancers and pulmonary emphysema may be of occupational origin in this worker population.

Six patients with end-stage emphysema (age 44 +/- 2 years) underwent double lung transplantation (Tx) from June 1988 through May 1990. All suffered from severe inanition and required oxygen therapy. The ischemic time was 193 +/- 28 minutes. Post-Tx immune suppression was OKT3 (14 days), cyclosporine (trough levels of 150 +/- 25 ng/ml), azathioprine to keep WBC at 3,000 to 5,000/cu mm (1 to 3.0 mg/kg/day) and following OKT3, a tapering prednisone regimen. Two rejection episodes that occurred in two patients on post-Tx day 5 and 10 were treated with bolus doses of methylprednisolone. The mean hospital stay was 32 +/- 7 days (range, 20 to 69 days). Four patients required treatment of cytomegalovirus (CMV) infection: gastritis (+donor, +recipient) in one and CMV pneumonia in two (+donor, -recipient). A fourth (+donor, -recipient) had right-sided Candida empyema six weeks post-Tx, developed CMV and staphylococcal sepsis, and died 64 days post-Tx. One patient required pyloroplasty eight weeks post-Tx and one patient underwent tracheal suture line repair at eight weeks. During a follow-up of 81 patients months (range, 8 to 24 months), one patient had developed Epstein-Barr viral (EBV) induced lymphoproliferative disease in the lung and one patient had developed EBV lymphoma. Three patients are at work, one is continuing rehabilitation, and one is at home. Double lung Tx offers a definitive benefit to patients with emphysema; however, a prolonged postoperative course can be expected. Viral infections remain serious but treatable problems.

The aim of this paper is to report a very rare case of bronchobronchiolitis obliterans accompanied by mesenteric Castleman's lymphoma. A 45-year-old woman was admitted to our hospital with progressive exertional dyspnea. Chest radiography showed overinflated lungs suggesting emphysema and pulmonary function tests revealed severely restrictive as well as obstructive impairments. Selective alveolobronchogram and endoscopy using a thin fiberoptic bronchoscope (3 mm in diameter) demonstrated multiple obstructions of small bronchi. Using a biopsy forceps, a small piece of tissue of bronchial wall was obtained from the focus of obstructive change, which showed histologically nonspecific inflammatory change including granulation. Therefore, we diagnosed her disease as bronchobronchiolitis obliterans (BBO). In addition, she had a large abdominal mass. On operation, it was found to be located in the mesenterium. It was then removed and the histological examination revealed Castleman's lymphoma, hyaline-vascular type. After operation, the blood IgM level, which was high on admission decreased rapidly and her dyspnea was reduced, suggesting that Castleman's lymphoma was related to the pathogenesis of her respiratory disease.

The respirable fraction of an ore dust from the North-West of Western Australia was tested for biological properties by inhalation and intrapleural implantation trials using rats and mice. Pulmonary histology indicated significant levels of interstitial pneumonia occasionally associated with bronchopneumonia, bronchiectasis, emphysema, and lung collapse over that found in age-matched control animals. While there was a significant increase of the incidence of tumors in general in WAG inbred rats up to 2 years following dust exposure, this did not persist into old age. No mesotheliomas were induced by any treatments associated with iron ore dust, although the rats were shown to be susceptible to crocidolite asbestos-induced mesothelioma. In the mouse models, tumors which are normally seen only in aged animals were induced with a significant number of bronchial adenomas being recorded following intrapleural implantation of dust into inbred BALB/c mice. Leukemia/lymphoma associated with murine leukemia virus was increased following dust inhalation by inbred C57BL mice.

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 retrospective cohort study was performed on a group of 664 male workers employed for at least one month during the period 1942-1979 in a chemical factory. Both established and suspected carcinogens had been handled in the plant, primarily piperazine, but also urethane, ethylene oxide, formaldehyde, and organic solvents. A significantly increased mortality, compared with the regional death rate, was observed in the cohort. The increase was mainly due to violent deaths and cardiovascular diseases. No rise in death rates was observed for asthma, bronchitis or emphysema, in spite of other evidence of a high risk of occupational asthma, due to exposure to piperazine. A statistically significant increase in cancer morbidity was observed for malignant lymphoma/myelomatosis when an induction latency time of at least 10 years was used. Furthermore, an increase in bronchial cancer was noted, but it was statistically significant only when an induction-latency time of at least 15 years was used. A case-referent study within the cohort did not reveal any significant association between any specific chemical exposure and cancer morbidity.

During the last two years video-assisted operative thoracoscopy has introduced new impetus into thoracic surgery. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indications. The prerequisites, instruments, and operative techniques are discussed. In oncological thoracic surgery it still remains to be verified whether the criteria of radicality are fulfilled by this new technique. Using video-assisted operative thoracoscopy, we have successfully operated on 209 patients with the following indications: recurrent pneumothorax (n = 94), interstitial lung disease (n = 25), coin lesion (n = 20), pleural effusion (n = 17), hyperhidrosis (n = 14), mediastinal tumor or lymphoma (n = 10), thoracic empyema (n = 9), bullous emphysema (n = 8), pleural tumor (n = 5), hematothorax (n = 3), malignant pericardial effusion (n = 3), and chylothorax (n = 1). The advantages of this minimally traumatizing operating technique lie in a better view of the operative site, the objectively measurable reduction in postoperative restriction, less pain, earlier postoperative mobilization, and shorter hospital stay. This operating technique, in addition to being sparing, requires markedly less time than a thoracotomy. The disadvantages are the two-dimensional monitor picture and, especially, the loss of palpation.

A proportionate mortality study of a cohort of golf course superintendents was conducted using death certificates for 686 deceased members of the Golf Course Superintendents Association of America who died from 1970 to 1992. White males were included in the study population from all 50 states. The study objective was to compare mortality from this cohort to the general U.S. white male population. The proportionate mortality ratio (PMR) for all types of cancer was 136 (CI: 121, 152). Significant excess mortality from smoking-related diseases was observed. The PMR for arteriosclerotic heart disease was 140, which was significantly elevated (CI: 127, 155). In addition, the PMR for all respiratory diseases was 176 (CI: 135,230), while the PMR for emphysema was 186 (CI: 101,342). The PMR for lung cancer was 117 (CI: 93, 148). Mortality for four cancer types--brain, lymphoma (non-Hodgkin's lymphoma, NHL), prostate, and large intestine--occurred at elevated levels within this cohort: brain cancer PMR = 234 (CI: 121,454), non-Hodgkin's lymphoma (NHL) PMR = 237 (CI: 137,410), prostate cancer PMR = 293 (CI: 187,460), and large intestine cancer PMR = 175 (CI: 125,245). The PMR for diseases of the nervous system was 202 (CI: 123,333). A similar pattern of elevated NHL, brain, and prostate cancer mortality along with excess deaths from diseases of the nervous system has been noted among other occupational cohorts exposed to pesticides.

We investigated the causes of death of late sequelae of pulmonary tuberculosis. Chronic respiratory failure is one of the most frequent cause of death in the patients of late sequelae of pulmonary tuberculosis. We compared the long term prognosis of chronic respiratory failure in case of emphysema and pulmonary tuberculosis. In the patients with chronic respiratory failure by pulmonary emphysema, the prognosis was poor in those with pulmonary hypertension. But in case of late sequelae of pulmonary tuberculosis, prognosis was not affected by presence or absence of pulmonary hypertension. The determinants of prognosis of late sequelae of pulmonary tuberculosis are the indication of home oxygen therapy, malnutrition, and hypoxemia. Fungal infection, especially aspergilloma, is a common secondary infection of late sequelae of pulmonary tuberculosis. We investigated forty-two cases of aspergilloma as late sequelae of pulmonary tuberculosis, and of those 15 patients died. The causes of death were pneumonia and respiratory failure. Measurement of galactomannan antigen of aspergillus in serum using ELISA or PCR, it was apparent that the outcome was poor in the patients positive for antigen. It suggested that the prognosis of the patients with aspergilloma related with some degree of invasion of Aspergillus in parenchyma. It was reported that neoplasm is closely related to chronic tuberculous empyema. Lymphoma is most frequently complicated with chronic tuberculous empyema, and squamous cell carcinoma, adenocarcinoma, sarcoma and carcinoid were reported as complication of chronic empyema. We reported the case of angiosarcoma, originated from chronic empyema in left thoracic cavity formed after being treated for tuberculosis with artificial pneumothorax. Recently, the number of patients with late sequelae of pulmonary tuberculosis have been decreased, but some severe cases of patients of pulmonary tuberculosis will suffer from late sequelae of pulmonary tuberculosis, and that is still a great problem of the clinical course of pulmonary tuberculosis.

Common complications of cardiac transplantation include infection, rejection, accelerated coronary artery atherosclerosis, and lymphoproliferative disease. The authors reviewed radiographic and computed tomographic (CT) features of cardiac transplantation and its complications in a series of 232 patients (with 89 complications and 49 deaths). Normal postoperative findings in the first few weeks after surgery included enlarged cardiac silhouette, pneumomediastinum, pneumothorax, pneumopericardium, subcutaneous emphysema, and mediastinal widening. Infection was the most common complication, with pneumonia being the leading infectious condition (28 cases, with Aspergillus [n = 11] and cytomegalovirus [n = 10] being the most common pathogens) and the cause of death in seven cases. Although many cases of pulmonary infections occur in the first 3-4 months after surgery, in this series several cases developed up to 3 years afterward. Radiographic signs of acute rejection were nonspecific in the eight patients affected who died, and endomyocardial biopsy was used to confirm the suspected diagnosis. Accelerated atherosclerosis occurred in 13 patients between 10 months and 6.5 years after transplantation and led to death in eight. Lymphoproliferative disorders, which range from benign lymphoid hyperplasia to malignant lymphoma and which are the third leading cause of death beyond the immediate perioperative period in heart transplant recipients, developed in four patients who later died. Other complications related to endomyocardial biopsy and cardiothoracic surgery (i.e., pneumothorax, hemothorax, pneumomediastinum, mediastinitis, aortic dissection, aortic pseudoaneurysm, and pulmonary embolism) occurred in 31 cases and were diagnosed with radiography and CT.
