A survey of the health, social and economic problems of the village of A1 Awayda, in Gezira province, Sudan, by medical students, was conducted over 2 weeks as part of their field training research and rural development curriculum. A 40% random household survey was based on a pretested structured questionnaire. The village comprises 195 households of 1201 people, with 40% under 15. As a result of the Sennar Sugar Scheme begun in 1978, 58% of the population work in the sugar factory. Rain-fed crops have failed for the last 2 years because of drought, and subsistence acreage has contracted because of sorghum planting for sugar. Sanitation consists of latrines in 15% of houses. People are at risk of contracting schistosomiasis from crossing the irrigation canal to reach the well. The diet is based on the staple starch, dura in the form of kisra. Breast feeding is continued for 1-2 years, with 47% supplementation by bottle or kisra or rice water at an average of 7 months. The major health problems are malaria, schistosomiasis, cough and diarrhea. 54% of families were immunized. 11.5% of women used modern contraceptives. Non-users cited religion as a reason for non-use. Female circumcision is common. It was recommended that latrines be dug, and that health education, immunization, prenatal care and family planning be provided.

A survey of respiratory symptoms were carried out among 200 female and 734 male workers in the Jute Factory at Kumasi. Dust concentration was also measured in various sections of the factory. The Batching and Preparing sections of the factory were the most dusty areas. Respiratory symptoms were commoner (or worse) in those working in dusty areas of the factory than office workers who work in a relatively clean environment. Occurrence of symptoms was related to degree but not the duration of exposure. Prevalence of symptoms was not influenced by age or sex but was increased by smoking. Cough, and sputum were the commonest symptoms. There were no significant objective signs of airways obstruction. Monday tightness and wheeze were rare complaints among the jute workers.

This paper presents the results of an investigation of respiratory symptoms and lung function of 404 workers who had been exposed to jute dust in a jute mill. Measurement of total dust concentration and analysis of dust composition were also conducted. Most workers in the jute mill were exposed to jute dusts containing less than 5% silica, whereas a few workers were exposed to dusts containing approximately 10-15% silica. Male smokers and nonsmokers in the dust-exposed group had a higher prevalence of cough and chest tightness compared with those in the control group. Among dust-exposed workers, female nonsmokers had a significantly higher prevalence of cough, chronic bronchitis, chest tightness, and dyspnea than those in the control group. Lung function tests showed that dust-exposed workers had a greater incidence of abnormal lung function than did control workers, as measured by percentage of predicted forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1.0), and FEV1.0/FVC. Dust exposure was the main cause of respiratory symptoms and abnormal values of FEV1.0, but both cigarette smoking and dust exposure contributed to the abnormal values reported for FEV1.0.

The prevalence of asthma in the South Fore region of Papua New Guinea was found to be 7.3%, which is thought exceptionally high for highland areas in this country. To investigate the prevalence of asthma and of chronic airflow limitation in a different highland region with similar living conditions, adults and children from 7 villages in the Asaro Valley were interviewed. Questions were asked about smoking history and about past and present symptoms of cough, of shortness of breath, of chest tightness and of asthma. Of 743 adults interviewed, 206 underwent a clinical study with measurements of lung function, bronchial responsiveness and skin prick tests. Dust was collected from the floors and blankets of 36 houses for counts of house dust mites. We did not find any children with symptoms of asthma. Only 2 adults (0.3%) had symptoms consistent with asthma, and a further 6.2% had symptoms and/or lung function consistent with chronic airflow limitation. Most bronchial hyperresponsiveness was associated with asthma or with chronic airflow limitation. The prevalence of atopy was similar in the Asaro and South Fore populations, but the South Fore had higher house dust mite counts in blanket dust. The low prevalence of asthma in the Asaro Valley is unexplained in terms of factors normally associated with asthma. Because asthma in this area does not appear in childhood and only develops in a small proportion of adults, it may be of different aetiology to asthma in Caucasian populations.

Ten asthmatic children with a history of cough and wheeze after drinking a cola drink performed histamine inhalation tests before and 30 minutes after a drink of Pepsi-Cola, soda water, and water on three separate study days. There was no significant change in baseline peak expiratory flow after any of the three drinks. Sensitivity to histamine was increased after the cola drink (p less than 0.005) but was not significantly different after soda water or water. The detection of change in sensitivity to histamine appears to be a simple and effective method of testing for food sensitivity in asthma.

A 49-year-old woman used an automatic bed cleaner on October 18, 1990. Eight hours later, she was admitted to a hospital complaining of coughing and fever. The chest X-ray film showed small granular shadows in both lower lung fields. After a few days of antibiotic therapy, these symptoms had disappeared. She used the bed cleaner again on the afternoon of November 15, 1990. The next day, she was admitted to our hospital because of coughing and fever. An environmental provocation test with the bed cleaner induced the same symptoms. Dust from the bed cleaner stimulated her lymphocytes. Hypersensitivity pneumonitis from the dust of a bed cleaner was diagnosed.

The active principle of chilli is capsaicin which when inhaled induces cough and transient increase in airway resistance through selective stimulation of sensory nerves in the airway. The present study was aimed at determining whether workers exposed to chilli dust showed ventilatory changes as in the pharmacological model. Twenty-five men with an average age of 28.5 years employed in five chilli grinding factories in Sri Lanka for an average of 6.6 years (range 3 months to 20 years) were clinically examined. Their ventilatory measurements were recorded before and after a Monday workshift. A control group was similarly examined. Dust levels in the respective chilli grinding factories were monitored. Fifteen men (60 per cent) had initial symptoms including cough on recruitment, but these passed off in 3 weeks to 6 months. There was no statistically significant across-shift change in ventilatory indices in chilli grinders when compared to the controls, nor was there a significant difference in the pre-shift measurements in the two groups. It is concluded that the airway resistance that occurs in the pharmacological model is too fleeting, if present in chilli grinders, to be recorded under ordinary conditions.

This study surveyed wood dust exposure levels and pulmonary hazards among wood mill workers. Dust concentrations as measured by six-stage cascade impactors were high in work areas of grinding and screening. Total dust concentrations for these dusty activities ranged from 4.4 to 22.4 mg/m3, and the respirable proportions were between 2.4% and 50.2%. The dust level in the sawing work was 2.9 mg/m3. Although symptoms of cough and phlegm were higher in smoking workers than in nonsmoking workers, the prevalence of respiratory symptoms in the exposed workers was not significantly higher than in the controls. However, the incidence of symptoms such as chronic phlegm and chronic bronchitis in the nonsmoking high-exposure workers was significantly higher than in nonsmoking controls. The mean values of MMF, PEFR, and FEF25% were significantly lower in the exposed workers than in controls for both smokers and nonsmokers. The pulmonary function deficits, with the exception of FEV1.0/FVC, also showed a significant trend with increasing levels of wood dusts exposure classified by job titles for both smokers and nonsmokers. After adjustment for age, sex, height, and smoking status, all parameters of pulmonary function were significantly lower in exposed workers than in controls and showed a declining trend with increasing exposure levels classified by job titles. These results indicate that high level of wood dust exposure in the wood mill industries may lead to pulmonary hazards. Engineering control and industrial hygiene are mandatory for dusty activities.

Health hazards associated with wood dust exposure have been investigated in various industries. This study surveyed wood dust exposure levels and pulmonary effects among joss stick workers. Greater dust concentrations, as measured by six-stage cascade impactors, were observed in work areas where joss sticks were produced and incense was mixed than in other work areas. Total dust concentrations for these two high dust activities ranged from 9.9 to 42.7 mg/m3, and respirable proportions were between 2.0% and 54.6%. Higher dust levels were observed for dry joss stick production methods than for wet production methods. Dust levels for all other performance areas were lower than the permissible exposure level of 10 mg/m3. Although symptoms of cough and phlegm were higher in smoking workers than in nonsmoking workers, the prevalence of respiratory symptoms for exposed workers was not significantly higher than for the controls. The prevalence of pulmonary function deficits and the values of FEF25% and FEF75% in the exposed workers were significantly worse than those in the controls. But no difference was found between the male controls and the male exposed workers, the high-exposure group. Respiratory symptoms and pulmonary function also did not show a dose-response trend with the exposure levels estimated by correlation with worker job titles and duration of employment. No suspected case of pneumoconiosis was found from the chest radiographs. These results suggest that wood dust exposure in the joss stick industries might not lead to significant pulmonary damage.

Take special care when recommending a product to people with a pre-existing medical condition (e.g., high blood pressure, stomach problems, asthma). It is safer to advise them to consult their pharmacist or doctor if there is a possibility of adverse drug interaction. Be aware of the possibility of overdosage (e.g., some patients take a large number of remedies simultaneously and may unwittingly be taking too much paracetamol, aspirin or ibuprofen). Green or yellow sputum suggests the patient has a bacterial infection in addition to a cold, and consulting a doctor is advisable. Enquire whether a cough is productive ("loose" or "chesty") or non-productive "dry, "tricky" or "irritating") so that you can advise on appropriate product. Productive coughs are helped by expectorants. Dry coughs are helped by suppressants. Cough preparations often contain antihistamine which may cause drowsiness, so be aware of this when advising a patient. For young children a paediatric formulation is advisable. Many of the main brands of cough and cold medicines have infant or junior varieties. Vapour products, often using substances like menthol placed on a tissue near the child but out of reach, can be very effective for blocked noses. Sugar-free preparations should be used for children (and adults) where possible, to avoid the risk of tooth decay. If patients suffer from repeated colds and coughs, and complain of feeling "run down", questioning may reveal that they have a poor diet. In that case, recommending a vitamin supplement or tonic and advice on a healthier diet may be appropriate. A persistent cough should receive medical attention.
