Accidentally occurring hydrocarbon poisoning during early childhood is a frequent and in most cases benign event. Nevertheless there is a potential risk of more serious consequences. We describe such a case. Respiratory symptoms are of the greatest concern. They include cough, tachypnoea, and in the more serious cases cyanosis and respiratory failure. Moreover, symptoms from the gastrointestinal tract are common. Treatment includes prevention of aspiration, symptomatic treatment and in more serious cases respiratory support.

Respiratory symptoms and ventilatory capacity were studied in a group of 288 workers (259 women and 29 men) employed in a confectionery plant. A group of workers (96 women and 31 men) not exposed to confectionery manufacture were also studied as controls. The prevalence of chronic respiratory symptoms was higher in exposed than in control workers, being greatest for confectionery workers exposed to the dust of flour, talc, and starch and the vapours of alcohol. Chronic bronchitis was reported by 7% of the women and 21% of the men, and chest tightness was reported by 27% of women and 66% of men. There was a high prevalence of acute irritative symptoms during the workshift in all groups of confectionery workers, especially for cough, dyspnoea, burning and dryness of the throat, and eye irritation. For all groups of confectionery workers there were statistically significant across shift reductions in ventilatory capacity, being most pronounced for maximum flow rate at 50% of the control vital capacity (FEF50; range 4.6-13.0%) and at 25% of the control vital capacity (FEF25; range 4.7-22.3%). Preshift values of FEF50 and FEF25 were significantly lower than predicted values. The data suggest that some workers employed in confectionery plants may develop acute and chronic respiratory symptoms associated with changes in lung function.

Respiratory symptoms and past history of chest disease as well as spirometric tests were investigated in 72 of 86 (83.7%) employees of a middle sized quarry in Rio de Janeiro, Brazil. Seventy one were men (98.6%), and the mean age was 36.2 +/- 9.3 years (20-65). Forty two (58.3%) had occupations considered as highly exposed to dust, and 30 (44.7%) were considered as lightly exposed. Forty (55.6%) were smokers, 20 (27.8%) never had been smokers and 12 (16.7%) were former smokers. Symptoms and past history were investigated with a questionnaire based on international models, and adapted for the Brazilian public. A high prevalence of symptoms (except for dyspnea) was noted: 47 (65.3%) had one or more symptoms-there was cough in 31.9%, expectoration in 41.7% dyspnea in 9.7% and wheezing in 33.3%. The symptoms were found to be associated mostly with a past history of chest disease, and also with smoking, factors which explained, in part, the presence of the symptoms. No association with a higher exposure to dust was found. The exposure to dust did not explain the symptoms. The spirometric tests were performed on a 6 liter bell spirometer. The means of the parameters were lower than one would expect in a non selected population sample--89.9 +/- 11.2% of predicted for the Forced Vital Capacity (FVC), 90.1 +/- 12.9% for the Forced Expiratory Volume in 1 second (FEV1) and 92.9 +/- 32.7% for the Forced Expiratory Flow between 25% and 75% of the FVC (FEF25-75). However, the proportions of abnormal results were comparable to the reported ones from unselected samples. There was no statistically significant influence of higher dust exposure, past history or smoking on the means of the results. It is concluded that, in this sample of quarry employees, no association between respiratory symptoms or spirometric results and dust exposure could be demonstrated. There was an association between the symptoms, but not with the spirometric results, and a past history of chest disease, as well as with smoking.

We conducted an assessment of respiratory health status including questionnaire and spirographic measurements in 54 male swine producers age 36.3 +/- 11.1 years (mean +/- SD) who worked an average of 10.7 +/- 6.3 years in the industry and spent 4.7 +/- 2.1 hours per day in the swine barns, and we also measured atmospheric contaminants including carbon dioxide, ammonia, total dust, respirable dust, and airborne endotoxin. Mean atmospheric dust contaminant levels were as follows: carbon dioxide, 2632 +/- 807 ppm; ammonia, 11.3 +/- 4.2 ppm; total dust, 2.93 +/- 0.92 mg/m3; respirable dust, 0.13 +/- 0.05 mg/m3; and endotoxin, 11,332 +/- 13,492 endotoxin units/m3. Of these, endotoxin related to forced vital capacity (P < .05) and endotoxin x hours per day was related to forced vital capacity (P < .05) and to forced expiratory volume in 1 second (P = .06). Respiratory symptoms and lung function studies did not relate to categories of low, medium, and high exposure to respirable dust. However, categories of endotoxin (available on 46 workers) related to respiratory symptoms (cough, P = .02; chronic bronchitis, P = .06; and to forced vital capacity, P < .01). These data suggest that respiratory health status relates to endotoxin levels but not to dust level exposures in the presence of low dust levels and indicates that control measures should include endotoxin as well as dust control.

A cross sectional study was carried out to determine whether schoolchildren in a specific locality exposed to pollution from steam coal dust have an excess of respiratory symptoms compared with children in control areas. A total of 1872 primary schoolchildren (aged 5-11 years) from five primary schools in the Bootle dock area of Liverpool (exposed area), five primary schools in South Sefton (control area), and five primary schools in Wallasey (control area) were studied. A questionnaire was distributed through the schools and was completed by the parents of the children. The questionnaire inquired about respiratory symptoms (cough, wheezing, and shortness of breath), allergy, atopy, smoking, and socioeconomic factors. Height, weight, and peak expiratory flow were measured. Compliance was good (92%) and similar in the three study areas. The children in the three areas were of similar mean age (7.5 years), height (1.24 m), sex ratio, and had a similar prevalence of paternal (6.2%) and maternal (7%) asthma. The exposed zone contained more unemployed parents (41, 29, and 29% respectively), more rented housing (64, 45, 34%), and more smoking parents (71, 60, 59%) than the control areas. Respiratory symptoms were significantly more common in the exposed area, including wheeze (25.0, 20.6, and 17.5%), excess cough (40.0, 23.4, and 25.1%), and school absences for respiratory symptoms (47.5, 35.9, and 34.9%). These differences remained significant even if the groups were subdivided according to whether or not parents smoked or were employed. Multiple logistic regression analysis confirmed the exposed zone as a significant risk factor for absenteeism from school due to respiratory symptoms (odds ratio 1.55, 95% confidence interval 1.17 to 2.06) after adjusting for confounding factors. Standard dust deposit gauges on three schools confirmed a significantly higher dust burden in the exposed zone. An increased prevalence of respiratory symptoms in primary schoolchildren exposed to coal dust is confirmed. Although the association with known coal dust pollution is suggestive a cross sectional study cannot confirm a casual relation and further studies are needed.

The clinical and radiological features in 38 infants less than 3 months of age with tuberculosis proved by culture are described and may aid early diagnosis of this often fatal condition. Respiratory symptoms, cough in 33 (87%) and tachypnoea in 31 (82%), were the commonest presenting symptoms. Twenty five infants (66%) had hepatomegaly and 20 (53%) splenomegaly. Mantoux testing gave an induration of > 15 mm in three of 17 (18%) infants. In a further five a Tine test gave confluent response. Chest radiography in 27 infants showed miliary tuberculosis in seven (26%) and hilar or paratracheal adenopathy in 14 (52%) and 10 (37%) respectively. Compression of either the bronchi or trachea or both was noted in 15 (56%). Detection of this complication was aided by high kilovolt radiographs. A culture of Mycobacterium tuberculosis was obtained from gastric aspirate in 35 (92%) infants, but positive cultures were also obtained from cerebrospinal fluid, tracheal or bronchial aspirate and liver and lymph node biopsy. Of 30 mothers evaluated seven (23) had previously unsuspected pulmonary tuberculosis.

Respiratory symptoms and ventilatory capacity were studied in 259 female confectionary workers and in 65 non-exposed controls. Most of the chronic respiratory symptoms appeared more frequently among the exposed workers, particularly if they worked in exposure to flour, talc, starch, acids and alcohol. There was a high prevalence of acute symptoms that developed during work shift. This was true especially of cough, dyspnea, burning and dryness of the throat and eye irritation. The exposed workers exhibited statistically significant acute reductions of ventilatory capacity. Those were particularly pronounced for FEF50 (range: 4.6-13.0%) and FEF25 (range: 4.7-22.3%). The measured preshift values of ventilatory capacity were significantly lower than the predicted normal values. The administration of disodium chromoglycate (DSCG 40 mg) significantly diminished mean across-shift reductions in all ventilatory capacity tests. Data suggest that sensitive confectionery workers may develop acute and chronic respiratory symptoms accompanied by acute and/or chronic changes in ventilatory capacity.

The clinical features, chest radiographs and computed tomographic (CT) images were evaluated in 11 cases with serologically proved adult measles complicated with pneumonia (10 were previously healthy and one had sarcoidosis). Pneumonia appeared during the rash period in all cases. Respiratory symptoms were cough (9/11), dyspnea (3/11), and hypoxemia (10/11). Pneumonia manifestations were detected in only 4 cases by chest radiograph; on the other hand, they were seen in all cases by CT scan and consisted of ground-glass opacities (73%), nodular opacities (64%) and consolidation (27%). CT seems to be a useful method to detect measles pneumonia if it is suspected. Measles pneumonia in previously healthy patients had a good prognosis, as the hypoxemia disappeared within 6 days in all cases. The sarcoidosis patient showed prolonged pneumonic shadows and period of hypoxemia. Measles pneumonia occurring in a host with cellular immunodeficiency may have a severe clinical course.

In this study we evaluated data from a sample of 973 never-smoking women, ages 20-40, who worked in three similar textile mills in Anhui Province, China. We compared prevalence rates of respiratory symptoms across homes with and without coal heating and homes with different numbers of smokers. Multiple logistic regression models that controlled for age, job title, and mill of employment were also estimated. Respiratory symptoms were associated with combined exposure to passive cigarette smoke and coal heating. Effects of passive cigarette smoke and coal heating on respiratory symptoms appeared to be nearly additive, suggesting a dose-response relationship between respiratory symptoms and home indoor air pollution from these two sources. The prevalence of chest illness, cough, phlegm, and shortness of breath (but not wheeze) was significantly elevated for women living in homes with both smokers and coal heating.

Respiratory symptoms and pulmonary function were studied in a cross-sectional survey of Portland cement workers in southern Taiwan. The study cohort consisted of 661 cement workers who were classified into low, medium, and high exposure groups with mean exposure values of 0.22, 0.55 and 1.24 mg/m3 of respirable dust concentrations, respectively. The prevalence of respiratory symptoms was not found to be significantly related to exposure, with the exception of a higher prevalence of coughing found among the heavy exposure group (OR = 1.55, P < 0.05). Both non-smoking and smoking cement workers showed no significant differences in the pulmonary function indices among the three exposure groups.
