To assess clincial effects of precipitated amorphous silica (PAS), the authors reviewed serial spirograms, respiratory questionnaires, and chest radiographs of 165 workers exposed for a mean of 8.6 years. Monthly exposure was graded on a 1 to 4 scale and a "cumulative exposure index" (CEI) calculated for each worker from the sum of measured exposure. A "mean exposure index" (MEI) was calculated by dividing the CEI by total months exposed. Sputum production and dyspnea were inversely correlated with CEI, while cough and dyspnea correlated with mean pack-years of smoking but not PAS exposure. Linear regression analysis of yearly change of all pulmonary function variables (FVC, FEV1, FEV1/FVC, FEF25-75) showed no correlation with either the dose of PAS (CEI) or total years of exposure. Among 44 workers with a mean exposure time of 18 years (range 10-35 years), yearly decline of FVC and FEV1 were similar to the overall group. Of 143 workers with serial radiographs and exposure to only PAS, none had radiographic pneumoconiosis. Respiratory symptoms in PAS workers correlate with smoking but not with PAS exposure, while serial pulmonary function values and chest radiographs are not adversely affected by long-term exposure.

Respiratory symptoms and personal history of allergy were examined in 1659 children, including the entire elementary school population of four villages of the Belgian Ardennes. Levels of atmospheric pollution were monitored during the survey and proved to be very low. It is suggested that socio-economic factors produce a small increase in respiratory symptoms, particularly in cough symptoms. A personal history of eczema and of hay fever was highly associated with dyspnea and wheezing.

Respiratory symptoms, disease and lung function were studied in 376 families with 816 children who participated in a survey in three USA towns. Parental smoking had no effect on children's symptoms and lung function. Also, there was no evidence that passive smoking affected either lung function or symptoms of adults. There was no association between prevalence of self-reported cough and/or phlegm in parents and their children. There was a highly significant association between the prevalence of wheeze in parents and their younger children, for whom parents reported this symptom. Wheeze in children was also significantly associated with a parental history of asthma, and lung function was lower in children with a family history of asthma. Even after accounting for height, weight, age, sex and race, children's lung function correlated significantly with parents' lung function. However, the contribution of familial factors (i.e., parents' lung function, smoking, and history of asthma) to children's lung function is small compared to the effects of height, weight and age.

A follow-up study of lung function tests and dust measurements was undertaken in ginnery workers employed in five ginning factories. Respiratory symptoms and respiratory function tests (FEV1 and FVC) were first recorded in 1967 on a total of 382 workers (323 permanently employed ginnery workers, 35 seasonal farfara workers, and 24 fire brigade men as controls). In 1969 after a six-month break from ginning before the start of the season, a follow-up study of lung function tests was undertaken on 96% of the same workers (306 ginnery workers, 35 farfara, and 24 fire brigade men). Because of the lapse of two years a new adjustment for age and height was made so as to compare the FEV1 measured in the follow-up study. The fire brigade men showed an expected fall in FEV1 during the two-year period, whereas the ginnery workers showed a rise presumably because they had had no dust exposure during the previous six months. The differences between the degree of change in these groups were statistically significant. In 1967 only the fine dust (less than 7 mum) was measured, while in 1969 the concentration of fine and medium dust, that is, less fly was measured. The factories were divided into three groups according to dust concentration. Comparison between the three factory groups and farfara shows a positive association between the level of dust concentration less fly and the prevalence of cough and phlegm. Since age did not appear to be a significant factor in the prevalence of byssinosis, comparisons between permanent workers in these three groups of factories and farfara workers taken separately were made without age standardization. The overall differences were statistically significant. There was a marked trend showing a positive association between prevalence of byssinosis and level of cotton dust concentration in the factories. The correlation between dust levels and the prevalence of byssinosis was nearly perfect when the time factor was included.

This report describes neurologic and respiratory symptoms among 26 engineers and contract laborers who used organic solvents and detergents to remove polychlorinated biphenyl contamination from a poorly ventilated factory basement. Neurologic symptoms included persistent central nervous system deficits; these developed in one worker after only 3 days. Respiratory symptoms included cough that persisted for more than 2 years. Laborers were more likely to report symptoms than were engineers. Appropriate ventilation or respirator use might have prevented the workers' morbidity. This incident serves as a reminder that organic solvent-related occupational illness continues to occur despite worker-health regulations and knowledge of preventive measures.

This study assessed the association between daily changes in respiratory health and respirable particulate pollution (PM10) in Utah Valley during the winter of 1990-1991. During the study period, 24-h PM10 concentrations ranged from 7 to 251 micrograms/m3. Participants included symptomatic and asymptomatic samples of fifth- and sixth-grade students. Relatively small but statistically significant (p less than 0.01) negative associations between peak expiratory flow (PEF) and PM10 were observed for both the symptomatic and asymptomatic samples. The association was strongest for the symptomatic children. Large associations between the incidence of respiratory symptoms, especially cough, and PM10 pollution were also observed for both samples. Again the association was strongest for the symptomatic sample. Immediate and delayed PM10 effects were observed. Respiratory symptoms and PEF changes were more closely associated with 5-day moving-average PM10 levels than with concurrent-day levels. These associations were also observed at PM10 levels below the 24-h standard of 150 micrograms/m3. This study indicates that both symptomatic and asymptomatic children may suffer acute health effects of respirable particulate pollution, with symptomatic children suffering the most.

A 41-year-old paint sprayer, who had worked with polyurethane paint since the spring of 1989, developed exertional dyspnea and dry cough and entered hospital on December 4, 1989. Plain chest X-ray film and a computed tomogram of the lung revealed diffuse micronodular shadows in both lower lung fields. DLco was shown to be significantly decreased in a pulmonary function test. A sample of bronchoalveolar lavage fluid showed increased T lymphocytes and a decreased CD4/8 ratio. A lung biopsy specimen revealed alveolitis, but neither Masson body nor granulomas were seen. Serum antibody specific to TDI-HSA was detected, and an environmental provocation test was positive. From these results, the patient was diagnosed as having isocyanate-induced hypersensitivity pneumonitis. We advised him to wear a compression-air mask when he worked, because he did not want to quit his job. Respiratory symptoms have not been seen since then, but careful observation was thought to be necessary. The involvement of type III humoral and type IV cellular immunity was suspected in this case.

We investigated the relationship of three phenotypic markers of atopy (allergy skin test reactivity, serum IgE level, and eosinophilia) to the prevalence of respiratory symptoms in 1,071 middle-aged and older men participating in the Normative Aging Study. Participants had all been health screened at the onset of the study in the 1960s to exclude individuals with asthma or other chronic respiratory diseases. Respiratory symptoms were grouped into three categories: asthma (adult onset) and other wheezing syndromes; cough and phlegm production; and hay fever. Multivariate logistic regression models were utilized to assess the independent relationship of each phenotypic marker to symptom prevalence adjusted for age, cigarette smoking, and the competing influence of the other markers. In this population, the prevalence of each symptom increased with serum total IgE concentration, this relationship being strongest for asthma. Skin test positivity (greater than or equal to 5 mm induration to one or more aeroallergens) was strongly associated with hay fever but was not significantly associated with symptoms of wheeze or cough and phlegm. Eosinophilia was associated with asthma and with phlegm production. The association of eosinophilia with phlegm production was present in skin test-negative as well as skin test-positive subjects and remained significant even after current smokers and individuals with asthma or hay fever were excluded. These data support the concept that asthma and hay fever are related to different immunologic host factors as reflected by expression of atopy phenotypes. Future investigations of immunologic factors in respiratory disease susceptibility should include, at a minimum, an assessment of all three phenotypic markers of atopy.

Respiratory symptoms are a common cause of distress in patients with advanced cancer. Optimal palliative therapy requires careful assessment and the appropriate use of symptomatic measures in conjunction with specific antitumor treatments. The etiology and management of the three major respiratory symptoms, dyspnea, cough and hemoptysis, are described. The indications for antitumor treatments and surgical procedures are briefly outlined, and symptomatic treatments, including drug and nondrug measures, are discussed in detail.

Respiratory symptoms and ventilatory capacity were studied in a group of 70 subjects employed as sewage workers. It was found that exposed workers had an increase in the prevalence of chronic respiratory symptoms when compared with control workers, although the difference was statistically significant only for chest tightness (p less than 0.01). In exposed workers there was a high prevalence of acute symptoms which develop during the shift being particularly pronounced for eye irritation, dyspnea and cough. A large number of sewage workers complained of skin disorders. Results of lung function testing demonstrated reduction of FEV1, FEF50 and FEF25 in relation to predicted normal values suggesting obstructive changes mostly located in smaller airways. Our data confirm that sewage workers are exposed to different occupational noxious agents which may lead to the development of chronic lung function changes.
