Respiratory symptoms and spirometric pulmonary function data [i.e., first-second forced expiratory volume (FEV1.0) and forced vital capacity (FVC)] for 128 (30%) males who were exposed to alkyl benzene sulphonate in a detergent factory and for 56 (76%) unexposed workers in the same factory are reported herein. Exposed subjects had been employed for 1 month to 15 yr, and they generally complained of cough and mucus secretions, nasal catarrh, chest pain, and breathlessness. Unexposed workers had been employed for 1 month to 13 yr and had a significantly lower (P less than .001) frequency of symptoms, as well as significantly higher (.01 greater than P greater than .001) FEV1.0 and FVC than the exposed workers. The reduction in pulmonary function of exposed subjects from the predicted was significantly higher (.01 greater than P greater than .001) than that experienced by the unexposed subjects. There was a significant 8-hr workshift depression in lung function. There was radiological evidence of pulmonary fibrosis, but lack of pre-employment chest radiographs renders this inconclusive. Respiratory symptoms in exposed subjects decreased with duration of employment, which probably indicates the exodus from the work force of those who could not tolerate the nonsoapy detergent.

Respiratory symptoms, forced vital capacity, and the single breath N2 test were assessed in male employees (25 to 54 yr of age) who had been employed for more than 5 yr in the mining industry in Manitoba. The results were compared with those in a similar group of men selected from the general population. The prevalence of cough and/or phlegm in both nonsmoking and smoking mining employees was significantly greater than that in the sample of the general population (p less than 0.05). In both nonsmokers and ex-smokers amongst the mining employees, the parameters derived from the single breath N2 test tended to be lower and maximal expiratory flow rates tended to be higher than in comparable groups in the general population sample. In smokers, FVC, FEV1, FEV1/FVC, maximal expiratory flow rates, RV/TLC, and the slope of phase III were significantly worse in smelter workers than in underground workers. Alterations in lung function in those who worked underground, but not in those who worked in the smelter, was related to the duration of employment in the industry. The data suggest that exposure to mining irritants may result in disorders of lung function, and that this effect is greater in cigarette smokers.

Six patients with breast cancer developed pulmonary toxicity following mitomycin therapy. The presenting symptoms were shortness of breath and a dry cough. The radiological pictures varied from a normal chest x-ray to extensive bilateral pneumonitis. The histological findings consisted of diffuse alveolar damage progressing to interstitial pulmonary fibrosis. Corticosteroid therapy resulted in complete resolution of pneumonia in one patient. Respiratory symptoms improved in 3 patients following discontinuation of the drug. Two patients with extensive bilateral pneumonitis, who were not treated with steroids, died of respiratory failure. Mitomycin-induced lung toxicity appears to be reversible with the discontinuation of drug and the administration of corticosteroids. Lung biopsy is necessary in order to rule out other diagnoses.

We measured nonspecific bronchial reactivity to inhaled histamine in 26 lifetime nonsmoking grain handlers and 29 lifetime nonsmoking unexposed control subjects matched for age, sex and specific conductance. Routine lung function tests revealed a total lung capacity that was higher in control subjects than in workers (P less than 0.05) with no difference in other subdivisions of lung volume, or expiratory flow rates between the two groups. An index of allergy was significantly greater in the control subjects than in the grain workers (P less than 0.01). None of the grain handlers was sensitive to grain dust by history or by skin tests. Respiratory symptoms (cough, sputum, dyspnea, or wheezing) were more prevalent in the grain workers than in controls (P less than 0.05). The mean concentration of histamine required to reduce the specific conductance by 35 percent was 4.5 +/- 2.0 mg/ml in grain workers and 5.9 +/- 3.0 mg/ml in controls (P less than 0.05). Chronic exposure to grain dust in nonallergic individuals appears to be associated with both increased prevalence of respiratory symptoms and increased nonspecific bronchial reactivity when compared to nonexposed control subjects.

Respiratory symptoms were studied in 119 patients operated on for fundoplication and crural repair because of gastroesophageal reflux disease (GERD). The effect of antireflux surgery and of smoking habits on their respiratory symptoms was evaluated. A questionnaire was completed before and after surgery in connection with esophageal investigations. Chronic bronchitis was present in 20% of the patients, 38% of whom were smokers. In the rest of the patients, 18% were smokers. Cough was reported by 34% and expectoration by 21%. After surgery the number of patients with cough and chronic bronchitis was reduced significantly in nonsmokers and to some extent in smokers. It is believed that fundoplication with distal anchoring of the longitudinal esophageal muscle will improve pharyngoesophageal function and thereby decrease aspiration and respiratory symptoms due to mis-swallowing.

Three cases with systemic rheumatic diseases who developed lung diseases compatible with BOOP were reported. Underlying diseases of these patients were: RA (1 case), SLE (2 cases). Respiratory symptoms were observed in one case such as dry cough at the time of diagnosis of BOOP. Chest radiography showed multiple infiltrates in 2 cases, bilateral reticular shadow in one case. In one case characteristic finding described as wandering shadow was observed. TBLB was done in 3 cases. Pathohistological findings were compatible with BOOP. Repeated Bacteriological examinations failed to demonstrate specific organisms implicated for lung lesions. Cytological studies of sputum and TBLB specimens were all negative for malignancy. Antibiotic agents including anti-tuberculosis drugs were not effective for pulmonary diseases. Moderate doses of prednisolone were effective in 3 cases. Although the open lung biopsy has been recommended for establishment of diagnosis of BOOP, in patient with systemic rheumatic diseases this invasive procedure is not always easily performed. Further characterizations of clinical and laboratory features are indicated for noninvasive diagnosis of BOOP.

Respiratory symptoms and ventilatory capacity were studied in 63 flour processing male bakery workers in Umtata, Transkei, Southern Africa. The controls were from a bottling plant in the same city. Both groups were black Africans from the Xhosa-speaking population. The studied population was nonsmoking and no significant difference was noted in age, race, sex, or height between the groups. The exposed workers had significantly lower forced expiratory indices than the control group. Mean percent predicted values of forced expiratory volume in one second (FEV1), forced expiratory ratio (FEV1/FVC x 100), forced mid-expiratory flow between 25% and 75% of FVC (FMF), forced expiratory flow between the first 200 ml and 1,200 ml of FVC (FEF 200-1,200), and peak expiratory flow rate (PEF) were, respectively, 11.2%, 20.0%, 31.0%, 27.4%, and 36.1% lower in the exposed group compared with the controls. The prevalence of forced expiratory ratio less than 70% in the exposed group was 37% while in the controls it was 8%. The prevalence of PEF rate less than 5 1/s in the exposed group was 32% while in the controls it was 11%. The exposed workers reported a significantly higher prevalence of respiratory symptoms compared to the controls. The prevalence of nasal symptoms, phlegm, and cough in the exposed workers was 53.9%, 30.1%, and 25.4%, respectively. The present study demonstrated that exposure to flour dust in flour processing workers in the baking industry is associated with significantly lower pulmonary functions and a higher prevalence of respiratory symptoms, and that these workers show signs of airway obstruction, compared to workers not exposed to flour.(ABSTRACT TRUNCATED AT 250 WORDS)

Allergic sensitization and symptoms from the airways in relation to air pollution were compared in 10-12-year-old school children (n = 1113) from urban Konin in central Poland and both urban and rural parts of Sundsvall in northern Sweden. The measurements included parental questionnaires, skin-prick tests and serial peak flow measurements during 2 weeks with simultaneous monitoring of outdoor air pollutants. The skin-prick test technique was validated by IgE antibody determinations. The levels of common industrial pollutants, SO2 and smoke particles were much higher in Konin than in urban Sundsvall and the levels of NO2 were similar. Various respiratory symptoms were more often reported among school children in Konin (except for wheezing and diagnosed asthma). Multiple logistic regression analyses yielded the following increased odds ratios for children in Konin as compared with the reference group (rural Sundsvall): chest tightness and breathlessness 3.48 (95% confidence interval 2.08-5.82), exercise-induced coughing attacks 3.69 (95% confidence interval 1.68-8.10), recurrent episodes of common cold 2.79 (95% confidence interval 1.53-5.09) and prolonged cough 4.89 (95% confidence interval 2.59-9.23). In contrast, as compared with rural Sundsvall, the adjusted odds ratio for a positive skin-prick test was decreased in Konin, but increased in urban Sundsvall, 0.58 (95% confidence interval 0.37-0.91) and 1.67 (95% confidence interval 1.15-2.42) respectively. The study confirms that living in urban, as compared with rural areas, is associated with an increased prevalence of respiratory symptoms and sensitization to allergens. These differences could be explained by air pollution. Respiratory symptoms were more common in a similar urban group of Polish children who were exposed to even higher levels of air pollution. These children, however, had a much lower prevalence of sensitization to allergens, as compared with the Swedish children. This indicates that differences in lifestyle and standard of living between western Europe and a former socialist country influences the prevalence of atopy.

Respiratory symptoms and lung function of 80 coal workers suspected of pneumoconiosis (pulmonary X-rays classified 0/1 or 1/0 according to International Labour Organisation classification) who worked for at least 10 years at face work (Ts) were studied in comparison with two control groups matched by age (+/- 2 years), height (+/- 5 cm), weight (+/- 10 kg) and smoking habits: the Tn group constituted by 80 coal workers who worked for at least 10 years at face work with normal pulmonary X-rays, and the HTn group constituted by 80 underground miners who worked mainly out of face work with normal pulmonary X-rays. The frequencies of cough, expectoration, chronic bronchitis or dyspnoea were significantly higher in Ts group than in the two others. The one-second forced expiratory volume to vital capacity ratio (FEV1/VC) was lower, closing volume to vital capacity (CV/VC) or to total lung capacity ratios (CV/TLC) were higher in Ts group than in the control groups. Unexpectedly, vital capacity (VC), one-second forced expiratory volume (FEV1), total lung capacity (TLC), compliance, diffusing capacity (DLCO) referred to alveolar volume (VA) were higher. In Ts group, the small rounded opacities were noted in the top part of the lung (56.9%), the irregular ones were distributed on the entire lung (65.5%). There were no relation between the category of small opacities and respiratory symptoms or lung function.

We have reviewed the records of 29 patients notified with miliary tuberculosis in Edinburgh from 1984 to 1992 and compared our findings with those for the 40 patients previously reported in Edinburgh from 1954 to 1967. The incidence of miliary tuberculosis has not changed. Respiratory symptoms of cough and dyspnoea were commoner in 1984-1992 (P < 0.001) perhaps reflecting the increase in mean age at presentation (73.5 vs. 59.4 years; P < 0.001). Mortality was 50% in 1984-1992, significantly higher (P < 0.05) than the 25% recorded in 1954-1967. Forty percent of cases in both time periods were of cryptic miliary disease. The diagnosis of cryptic disease tended to be made more often post-mortem and less often by a trial of anti-tuberculosis chemotherapy in 1984-1992. Our findings emphasize the current poor outcome associated with a diagnosis of miliary tuberculosis. It is important to consider this diagnosis in elderly patients with unexplained pyrexia and implement a trial of specific anti-tuberculosis chemotherapy to confirm it.
