We have studied mortality patterns in a large cohort of rubber workers. We have examined workers exposed to curing fumes, processing dusts, and industrial talc and have begun to evaluate exposures of these workers in detail. Gastrointestinal (especially stomach) cancer appears in excess in processing workers. Lung cancer is excessive in curing workers. Leukemia is increased generally. All three groups studied for respiratory disease have an increase in disease prevalence which is related to intensity and duration of exposure. Since both an increase in stomach cancer and respiratory disease is seen in processing workers, exposures in this area must be controlled. Since both lung cancer and chronic respiratory disease is excessive in curing rooms, this exposure must be controlled. The leukemia risk is probably related to solvents. Whether this is all explainable by past benzene exposure is unknown. Further studies are planned to refine our knowledge concerning these risks so that occupational disease in the rubber industry can be prevented.

20 cats in a cat home were treated prophylactically and therapeutically with Baypamun HK. The animals were allocated into three groups as described. 7 freshly admitted clinically healthy cats were treated prophylactically on day 1, 2 and 9 with 1 ml Baypamun HK (group I). 7 cats, who already were allocated for one year in the home and were sick of the feline respiratory disease complex were treated as described for group I (group II). 6 further cats, who also showed symptoms of the feline respiratory disease complex and had stayed for one year in the home were treated with physiol.saline solution according to group I (group III). From all cats blood samples were taken at day 1, 3, 10 and 17. The blood samples were checked for antibodies against feline calicivirus (FCV), feline herpesvirus (FHV), panleukopenia virus (PLV), feline peritonitis virus (FIPV) and feline immunodeficiency virus (FIV). Also the occurrence of the feline leukemia virus (FeLV) was evaluated. The cellular immunity was evaluated by means of the lymphocyte transformations test (LTT), nitroblue-tetrazolium reduction test (NBT) and cytochrome C-reduction test (CRT). Mean value and standard deviation was calculated from the results. The significance was determined by the t-test. The animals were examined clinically daily for 20 days for the feline respiratory disease complex. When necessary, the animals were treated by homeopathic and antibiotic products. At the time of admission to the home all cats were or had been treated with an attenuated panleukopenia vaccine. The serologic parameters were not influenced in the cats of group I.(ABSTRACT TRUNCATED AT 250 WORDS)

A follow-up was carried out on twenty-two children (thirteen of whom were newborn) who had been treated with porcine surfactant (Curosurf) for respiratory distress syndrome. All the infants were enrolled in the follow-up at different times after surfactant replacement to evaluate the clinical status and the incidence (if any) of respiratory disease, adverse drug effects and allergic conditions. Twelve of the twenty-two children treated completed the follow-up. Seven prematurely-born children died of endocranial haemorrhage; two children died of malignant development of the basal pathology (leukaemia). Treatment with pig surfactant appears to cause no allergic side effects. Skin and laboratory tests performed were negative.

Fire fighters are known to be occupationally exposed to many toxic substances. However, the limited number of previous studies has not demonstrated any consistent excess mortality from diseases of a priori concern, such as lung cancer, non-malignant respiratory disease, and cardiovascular disease. We studied 2,289 Seattle fire fighters from 1945 through 1983, and observed 383 deaths. Excess mortality from leukemia (SMR = 503, n = 3) and multiple myeloma (SMR = 989, n = 2) was observed among fire fighters with 30 years or more fire combat duty. Lung cancer mortality was elevated (SMR = 177, n = 18) among fire fighters 65 years old or older. We also analyzed the data by considering fire fighters at risk only after 30 years from first exposure. In this analysis, a trend of increasing risk with increasing exposure was observed for diseases of the circulatory system. For this cause of death, fire fighters with 30 years or more fire combat duty had a relative risk of 1.84 compared to those with less than 15 years of fire combat duty.

In order to investigate the incidence of pulmonary function complications following bone marrow transplantation (BMT), 17 patients with leukaemia and 8 with aplastic anaemia were sequentially assessed over a one year period. Before BMT, all the patients were free of respiratory symptoms and had both normal chest X-ray and routine lung function tests. However, 5 patients disclosed airway hyperreactivity. Aplastic anaemia patients had significantly lower haemoglobin-adjusted diffusing capacity for carbon monoxide (DLCO) than those with leukaemia, a finding significantly related to the lower haemoglobin values shown in the former individuals. Following BMT there were transient mild to moderate reductions in DLCO and static lung volumes; moreover, patients with leukaemia had lower DLCO than those with aplastic anaemia. Fourteen of the 25 patients had ventilatory defects, including 10 individuals with bronchial hyperresponsiveness. Post-BMT lung function changes were transiently accompanied by mild to moderate symptoms of respiratory disease in most of the patients.

Little is known of pulmonary function in survivors of acute lymphoblastic leukaemia (A.L.L.); this is despite the fact that some drugs used, most notably methotrexate, have well-recorded pulmonary toxicity, and the most common infections during therapy in most series are of upper and lower respiratory tract. As part of a survey of all cancer survivors attending the Royal Hospital for Sick Children in Edinburgh, 38 leukaemic patients, who had completed treatment 3 months to 14 years 6 months (median 6 years and 8 months) prior to survey were assessed with regards to their respiratory status. Each patient completed a questionnaire and had spirometry and lung volumes measured; 30 patients additionally had transfer factor for carbon monoxide (TCO) measured. There were 21 children, 11 adults, and 6 patients in the age range between child and adult. Of the 26 adults and children studied with complete data available, 17 (65%) had one or more low values for vital capacity (VC), total lung capacity (TLC), residual volume, or TCO. Mean VC, TLC and TCO were significantly lower than the mean of the predicted values (P less than .001). Gas transfer per unit lung volume (KCO) was normal in all cases. Few patients had symptoms of respiratory disease. There was an increased incidence of low TCO in patients diagnosed under 8 years of age. Impairment of lung growth could be a contributing factor to the observed abnormalities in pulmonary function. Impairment of pulmonary function in survivors of A.L.L. may be of significance for them in later life.

We describe the identification, experimental transmission, and pathogenesis of a naturally occurring powerfully immunosuppressive isolate of feline leukemia virus (designated here as FeLV-FAIDS) which induces fatal acquired immunodeficiency syndrome (AIDS) in 100% (25 of 25) of persistently viremic experimentally infected specific pathogen-free (SPF) cats after predictable survival periods ranging from less than 3 months (acute immunodeficiency syndrome) to greater than one year (chronic immunodeficiency syndrome), depending on the age of the cat at time of virus exposure. The pathogenesis of FeLV-FAIDS-induced feline immunodeficiency disease is characterized by: a prodromal period of largely asymptomatic viremia; progressive weight loss, lymphoid hyperplasia associated with viral replication in lymphoid follicles, lymphoid depletion associated with extinction of viral replication in lymphoid follicles, intractable diarrhea associated with necrosis of intestinal crypt epithelium, lymphopenia, suppressed lymphocyte blastogenesis, impaired cutaneous allograft rejection, hypogammaglobulinemia, and opportunistic infections such as bacterial respiratory disease and necrotizing stomatitis. The clinical onset of immunodeficiency syndrome correlates with the replication of a specific FeLV-FAIDS viral variant, detected principally as unintegrated viral DNA, in bone marrow, lymphoid tissues, and intestine. Two of seven cats with chronic immunodeficiency disease that survived greater than 1 year after inoculation developed lymphoma affecting the marrow, intestine, spleen, and mesenteric nodes. Experimentally induced feline immunodeficiency syndrome, therefore, is a rapid and consistent in vivo model for prospective studies of the viral genetic determinants, pathogenesis, prevention, and therapy of retrovirus-induced immunodeficiency disease.

A proportionate mortality study of police and firefighters in New Jersey was conducted using the records of a comprehensive retirement system. Three reference populations were used: U.S. general population, New Jersey general population, and police as a reference group for the firefighters. Overall neither group differed from the New Jersey male population in the cause of death. Analyses by latency showed an increase in skin cancer and cirrhosis in firefighters and cirrhosis in police. With increased time from first employment, an inverse association was found between heart disease and time of first exposure. This was reflected in statistically significant increased proportionate mortality rates (PMR) for arteriosclerotic heart disease (ASHD) (ICD 410-414) for both working police (PMR = 1.15) and firefighters (PMR = 1.2). Retired police and firefighters had PMRs of 0.96 and 0.98, respectively. Firefighters had a significant increase in nonmalignant respiratory disease (PMR = 1.98) and leukemia (PMR = 2.76) when the police were used as a reference group. Potential causes of the above findings are discussed.

Mortality analyses were carried out for 278 male hourly workers who were employed for at least 10 years at a gray iron foundry and who died between January 1, 1970 and December 31, 1981. Statistically significant excess proportional mortality due to non-malignant respiratory disease (SPMR = 177), lung cancer (SPMR = 148), and leukemia (SPMR = 284) was found among the 221 white males. Among nonwhite males there was a significant excess in proportional mortality due to circulatory diseases (SPMR = 143). White males in the Finishing classification experienced a significant excess of proportional mortality due to nonmalignant respiratory disease (SPMR = 279) and lung cancer (SPMR = 179). White males in the Core Room classification experienced an excess of proportional mortality due to nonmalignant respiratory disease (SPMR = 321). Case-control studies demonstrated a significant association between nonmalignant respiratory disease and the Finishing classification after controlling for the effects of age, prior occupations in coal mining or foundries, and smoking. A positive but nonsignificant association between lung cancer and Finishing was also found after controlling for age, prior work history, and smoking in case control studies.

Pulmonary function testing (PFT) was performed on 29 long-term survivors of childhood cancer. The patients, whose mean age was 11.7 years and whose mean age at diagnosis was 3.7 years, included 12 females and 17 males. Original diagnoses included 15 patients with leukemia and 14 individuals with solid tumors. Nine patients had received cyclophosphamide and 20 had received radiation therapy. Included in this latter group were five patients who had received radiation therapy to the thorax. Eight patients had acquired pneumonia during their treatment. Physical examination was normal in all the patients, and none had a history of acute or chronic pulmonary disease. PFT demonstrated an incidence of abnormalities in forced vital capacity (FVC) and/or total lung capacity (TLC) in 48% of the patients. Patients who were under 3 years of age at the time of diagnosis or who had received radiation to the thorax were more likely to demonstrate PFT abnormalities, but these differences did not reach statistical significance. The natural history of pulmonary function and subsequent respiratory disease in survivors of childhood cancer requires further definition.
