Retrospective study shows that a 1957 outbreak of pneumonia in Austin, Minnesota, was Legionnaires' disease. Between June 7 and August 9, 1957, 78 persons were hospitalized with acute respiratory disease of unknown cause. Most had fever, headache, cough, and pneumonitis; two died. Ages ranged from 14-83 years; half of the patients were aged 55 years or older. Eighty-seven per cent were men. There were no secondary cases. Forty-six (59%) of the 78 patients were employees at a local meat packing plant, in distinction to the area's total working population (32%). Serosurvey of 15 of the 1957 outbreak cases and 30 controls matched for age, sex, and either occupation or residence was carried out in 1979. Antibody titers were determined for Legionella pneumophila serogroups 1-4 by means of indirect immunofluorescence. Twelve (80%) of the 15 cases and 13 (43%) of the 30 controls had antibody titers of 1:64 or greater to one or more of the L. pneumophila serogroups. Significant differences in L. pneumophila antibody titers (prevalence and level) were found between cases and control groups matched for residence (serogroups 1-3) or occupation (serogroups 2 and 3). Only three of 20 Austin residents with pneumonia diagnosed between 1978 and 1980 had L. pneumophila antibody titers of 1:128 or greater (p less than 0.001), in comparison to cases. These serologic data and the 1957 clinical and epidemiologic observations support the contention that this is the earliest documented outbreak of Legionnaires' disease.

The survey objective was to obtain information concerning the incidence of lower respiratory tract illness in Polynesian infants and the general characteristics of children suffering from the disease. It was conducted as part of the case-finding exercise for an investigation into the role of cow's milk in the causation of the syndrome. All Polynesian babies born at Hutt Hospital in Hutt, New Zealand over the September 1, 1977 to May 31, 1978 period were identified from their mother's antenatal record. 317 infants were born to families in which 1 or both parents were Polynesian. 269 were interviewed at 5 months giving a followup rate of 85%. 42% had a history of lower respiratory tract illness as indicated by persistent moist cough associated with noisy breathing, wheezing, or breathlessness. 52 (19%) had either 2 or more episodes of such illness or had symptoms lasting for more than 1 month and were classed as severely affected. There were 62 (23%) with mild symptoms and 155 (158%) who had had no lower respiratory symptoms. The breast feeding rate of mothers whose children had severe lower respiratory symptoms was lower throughout the 5 month period. Significantly fewer children who had severe symptoms were being breast fed at 2 months (p0.02) and 4 months (p0.05). The differences just failed to reach significance at 3 and 5 months. There was a strong family history of wheezing in 1st degree relatives in those infants who had the more severe symptoms during the first 5 months. The parents of the severely symptomatic infants were found to live in damp accomodations more frequently than those of the mildly affected or asymptomatic children. The breast feeding pattern for those infants who had a family history of wheezing was similar to the pattern for all infants. Study findings document the high incidence (42%) of lower respiratory disease in the first 5 months of life in Polynesian infants in New Zealand, confirming common clinical experience.

Standardized respiratory disease questionnaires (ATS-DLD-78) were administered to 5,686 adult women. Risk factors were evaluated by logistic analysis that adjusted for multiple potential confounding factors. Among current smokers, the number of cigarettes smoked per day was consistently the strongest risk factor for chronic cough, chronic phlegm, wheeze, and dyspnea. The odds ratios for these symptoms in a smoker of 25 or more cigarettes per day relative to a smoker of 1--14 cigarettes per day were 4.74, 4.21, 2.05, and 3.71, respectively. Ex-smokers showed risks between those of current and never smokers. Cigarette tar content was a significant independent risk factor for chronic cough (p = 0.005) and of borderline significance for chronic phlegm (p = 0.077). High tar cigarette smokers in this population (average, 22 mg) had an odds ratio of 2.01 for chronic cough and 1.59 for chronic phlegm relative to low tar cigarette smokers (average, 7 mg). The effect of cigarette tar was linear and independent of cigarettes smoked per day. Smoke inhalation was a significant risk factor for chronic cough (p = 0.029) and for chronic phlegm (p = 0.038). Tar content and smoke inhalation were not significant risk factors for wheeze or dyspnea. Cigarette particulate content (tar) appears to be causally linked to cough and phlegm production., but the association of cigarette smoking and symptoms of wheeze and dyspnea may be more strongly related to the vapor phase of cigarette smoke.

All the Tahitian school children from 3rd to final grade were questioned by an auto-questionnaire in May 1979. 93% replied to the questions asked (3,870). The prevalence of upper respiratory infections was increased as well as broncho-pulmonary symptoms (cough or other lung disease) during the year under study when compared to a control group in Metropolitan France. This prevalence was significantly increased both in boys and girls who smoked. The incidence of frequent or chronic cough was most increased in the older pupils, boarders, those followed a technical curriculum and belonging to the lower socio-professional categories. Asthma was very frequent at 11.5%, had an equal sex incidence and was not linked to any identifiable factor--the same enquiry was done in the Bas-Rhin department in France 3 years before; Tahitian school children, in general, have double the incidence of respiratory disease that is found in the Bas-Rhin.

An outbreak of respiratory disease occurred in a herd of 34 calves and 5 cows in a barn. The disease which affected 24 calves and 1 cow, was characterized by coughing, fever, anorexia, nasal discharge and pulmonary rales. Two calves died 5 days after the disease outbreak and were necropsied. Bronchitis, bronchiolitis and alveolitis were among the lesions observed in these calves. Bovine respiratory syncytial virus was detected, in lung sections of the dead calves and also in nasal washings of some of the calves and one cow, by the direct fluorescent antibody technique and/or cell culture method. Seroconversion to the virus was detected in most animals tested.

Fifteen children who presented with chronic cough as an isolated manifestation of respiratory disease were evaluated for the presence of exercise-induced airway hyperreactivity. Pulmonary function tests using air and a helium/oxygen gas mixture were performed before exercise. Eight subjects were also evaluated by spirometry and maximum expiratory flow volume curves before and after isoproterenol inhalation on a separate day. Ten subjects had normal pulmonary function tests at rest and five had isolated minor abnormalities. No significant changes in pulmonary function tests were recorded after inhalation of isoproterenol in the eight subjects studied. Following exercise, all 15 subjects demonstrated changes in pulmonary function tests which were similar to those seen in children with mild exercise-induced bronchospasm. After institution of theophylline, exercise-induced decreases in flow rates low in the vital capacity were blocked in all subjects; however, several subjects had persistent mild decreases in peak flow. Within six months of discontinuing the theophylline, cough recurred in 11 of the 15 subjects. Nine subjects were restudied after return of their cough. Exercise again resulted in decreased lung function. Reinstitution of theophylline eliminated the cough in these nine subjects. This study demonstrates that chronic cough in some children may be a manifestation of airway hyperreactivity. Both the cough and the reactivity can be blocked with theophylline.

The purpose of this study was to determine the effects of air pollution on acute respiratory illness (ARI). Levels of air pollutants were monitored on a daily 24-hour basis at two schools in Akron, Ohio. The children at each school completed daily diaries which served as a screening mechanism for detecting ARI. Once an ARI was isolated, pulmonary function tests (PFT) were run during the symptomatic phase; once the child became asymptomatic, tests were continued for 2 wk. The results of this study indicate that SO2 and NO2 levels are higher at the school that borders industry. Results of daily diaries indicate a higher incidence of symptoms-especially cough, runny nose, and sore throat-in the polluted area. Pulmonary function tests indicate that respiratory airways are being compromised to a much greater extent at the polluted school, as indicated by significantly reduced levels of forced expiratory volume and maximal midexpiratory flow as compared to baseline. Recent evidence suggests that frequency and severity of ARI in childhood are related to chronic obstructive lung disease as adults. In lieu of these findings, it is suggested that the levels of SO2 and NO2 in urban areas be carefully considered, as they relate to acute subclinical syndromes and chronic clinical respiratory disease.

Eleven infants under six months of age with respiratory symptoms and positive results of serological tests for Chlamydia trachomatis, including an infant from whom chlamydiae were isolate, are presented. The three distinct patterns of illness in these infants were a bronchitis with paroxysmal coughing, a bronchiolitis syndrome, and a diffuse afebrile pneumonia. We conclude that chlamydial respiratory disease should be considered in Australian infants with the described features. The diagnosis can be confirmed by immuno-fluorescence.

Respiratory disease occupies a prominent position in the series of common diseases in calves. Efforts were made to take an inventory of possible causes of cough in calves at pasture. For this purpose, a number of calves on twenty-three, ten and eight mixed farms respectively were clinically studied during the period from 1975 up to and including 1977. Faecal, sputum and serum samples were collected to examine them for the presence of husk worm larvae, husk worm eggs, antibodies to specific viruses and lung worms. In 1978, titres of antibodies to lung worms were determined in the serum samples of a large number of calves from forty-five farms. From the findings obtained, conclusions were drawn regarding the prevention of virus and lung worm infections in calves at pasture and regarding the diagnosis and prevention of verminous bronchitis in these animals.

Of the twenty-three employees at a pharmaceutical plant manufacturing a new product containing papain, twelve had respiratory symptoms of cough, wheezing, dyspnoea, or chest paint. Most were studied with in-depth interviews by a doctor, extensive pulmonary function tests, and immunoserological tests for IgE and precipitating antibodies specific for papain, as well as total IgE antibodies to common natural allergens. There were significant correlates (all P values < 0.05) between the presence of specific IgE antibodies to papain and decreases of FEV1, FEF75--85, TLC, RV, and response to bronchodilators as percentage change from baseline for all spirographic flow rates. Atopic workers developed pulmonary symptoms and antipapain antibodies significantly sooner after papain exposure than did the others. Duration of exposure had no effect on symptomatology, pulmonary function, or immunological response. However, those judged to have the greatest amount of dust exposure per work-day had significantly more pulmonary symptoms (P < 0.005). Papain produced lung diseases by acting as an inhalant allergen rather than a proteolytic enzyme. Papain is a potent sensitizer in humans for the production of respiratory disease. The pulmonary reactions, based on physiological data, seem to involve small airways, alveolar, and interstitial lung tissue in an inflammatory rather than destructive manner, and thus resemble bronchitis and interstitial lung disease rather than pulmonary emphysema or typical bronchial asthma.
