The prevalence and severity of cough during long-term enalapril treatment were examined by comparing a cohort of 136 hypertensive patients who started treatment with enalapril with consecutive age and sex-matched patients who commenced nifedipine therapy during the same period. Cough and other symptoms were assessed by a questionnaire designed to avoid bias towards reporting cough. After a mean of 27 months' treatment patients on enalapril had an excess of persistent cough (16 per cent, 95 per cent CI 7-25, p less than 0.01), voice change (14 per cent, 95 per cent CI 2-27, p less than 0.05) and sore throat (10 per cent, 95 per cent CI -0.1 to 20.3 per cent, p less than 0.01) when compared to nifedipine-treated patients. The cough was usually dry, moderate or severe, paroxysmal, and troublesome at night. Cough tended to be more common in women (23 per cent vs. 7.2 per cent), non-smokers, and at higher doses of enalapril, but was not related to age, duration of treatment, or chronic respiratory disease. Dry cough commonly persists as a troublesome side-effect during long-term enalapril treatment, and is often associated with voice change and sore throat.

Chlamydia pneumoniae has recently been recognized as an important cause of respiratory tract disease, including atypical pneumonia. Serosurveys suggest that C. pneumoniae is endemic in most countries and is capable of causing outbreaks and epidemics of pneumonia, especially in countries where the antibody prevalence is relatively low. The population incidence of infection appears to be cyclical, with approximately 4-year cycles in the US (Seattle) and 6-year cycles in Denmark having been demonstrated. Pneumonia caused by the organism is unusual in young children in developed countries but may be an important cause of lower respiratory infections among children in developing and tropical countries. In otherwise healthy adults, C. pneumoniae pneumonia usually can be treated effectively on an outpatient basis. Patients with C. pneumoniae pneumonia often have a gradual onset of symptoms: a sore throat and hoarseness followed by a cough. Auscultatory and radiographic findings usually are prominent, even in patients with mild disease, and a cough and malaise may persist for several weeks or more after appropriate therapy. Microimmunofluorescence serologic testing is available in only a few laboratories. However, the new HL cell line holds promise of making culture and isolation of C. pneumoniae more widely available. Questions remain about the routes of transmission of C. pneumoniae, its incubation period, its role in lower respiratory disease in children in developing countries, the optimal antibiotic therapy, the existence and importance of chronic and latent C. pneumoniae infections, and the organism's association with nonrespiratory tract disease.

Clinical and serologic data were collected on 667 University of Washington students who presented to the David Hall Student Health Center between 1983 and 1987 with acute respiratory disease. Sera were tested for evidence of acute or past infections with Chlamydia pneumoniae strain TWAR, Chlamydia trachomatis, Mycoplasma pneumoniae, influenza A virus, influenza B virus, adenovirus, and respiratory syncytial virus. Pharyngeal swab specimens were cultured for C. pneumoniae and C. trachomatis, but not for the other agents. Evidence of acute infection with C. pneumoniae was found in 20 patients and evidence of an acute infection with M. pneumoniae in 29 patients. C. pneumoniae was associated with 9% and M. pneumoniae with 11% of 149 pneumonias diagnosed clinically, and with 20% and 22%, respectively, of the 59 pneumonias confirmed on chest radiograph. There was no evidence of seasonality in C. pneumoniae or M. pneumoniae infections. Compared with patients with M. pneumoniae, patients with C. pneumoniae were less likely to have a temperature greater than 37.8 degrees C (10% vs. 34%), but were more likely to present with a sore throat (80% vs. 52%) or hoarseness (30% vs. 3%). The mean number of days from onset of symptoms until enrollment was longer in patients with C. pneumoniae infections than in those with M. pneumoniae (12.8 vs. 7.9 days), or those with a viral infection (12.8 vs. 7.3 days), suggesting a more gradual onset of disease caused by C. pneumoniae.

Weekly data for seven conditions reported to the weekly returns service of the Royal College of General Practitioners' Birmingham research unit over a 52-week period have been compared with those reported to the Oxford regional sentinel practice scheme. The mean weekly recorded rates for otitis media, asthma and intestinal infectious disease were similar in both systems; in the weekly returns service, mean weekly rates for common cold, acute bronchitis and influenza/influenza-like illness were approximately twice and for sore throat/tonsillitis slightly higher than rates in the Oxford scheme.In the weekly returns service no recommendations are made about criteria for diagnosis but in the Oxford scheme diagnostic criteria agreed by the participants are used. Where rates in both monitoring systems are the same, agreed criteria are likely to be conventional clinical practice and therefore superfluous. Where rates are different, the use of criteria enhances specificity of the information content but results in an underestimation of the total incidence of - respiratory disease presented to general practitioners.For common cold, acute bronchitis, otitis media and influenza/ influenza-like illness the associations between the rates in the two systems were high (R>/=O. 79), as might be expected, but these high values cross validate both recording systems in their monitoring of trends. For the remaining (non-epidemic) conditions the associations were low. There were no significant associations between the rates for asthma and the upper respiratory infectious diseases in either recording system, which suggests there was effective discrimination of asthma.

Mycoplasma hominis seldom colonizes the human respiratory tract and only rarely causes acute respiratory infection. It can be recovered from the respiratory secretions of 1-3% of healthy persons and of less than or equal to 8% of persons with chronic respiratory disease, but it has not been implicated definitely in the etiology of this disease or in the exacerbations that characterize its course. M. hominis has been isolated from less than or equal to 6% of persons with acute pharyngitis or acute upper respiratory tract illnesses and can induce exudative pharyngitis in susceptible volunteers when administered intranasally and oropharyngeally. Colonization of the respiratory tract by M. hominis occurs in approximately 15% of persons who engage in oral-genital sexual practices, but colonization alone is not necessarily associated with sore throat or other upper respiratory diseases. Although M. hominis has been recovered from adults with pneumonia more often than from controls, a pathogenic role in pneumonia of adults has not been established. Under special conditions, e.g., neonatal pneumonia, M. hominis appears to be pathogenic for the lower respiratory tract. Thus M. hominis probably is only an occasional respiratory pathogen in the adult and a rare "opportunistic" pathogen of the respiratory tract of the neonate.

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.

The association between cooking fuels and the risk of respiratory disease in preschool children in Lucknow, India was studied. We interviewed mothers of 650 study children, randomly selected from among 28 urban poor neighborhoods. Children were eligible if they were less than five years of age, free of congenital heart disease, malignancy, and compromised immune status. Respiratory disease (defined as one or more of the following: runny nose, cough, sore throat, breathlessness, and noisy respiration) was assessed by observation. Exposures included the types of cooking fuels and duration of their use in the last week and other potential predictors of respiratory disease. Odds ratios (ORs) for disease were adjusted for covariables using multiple logistic regression. The point prevalence of respiratory disease was 14.5%. Cooking fuels used were wood (56.0%), kerosene (24.2%), coal (19.2%), gas (15.4%), and dung cakes (8.6%). Use of dung cakes, a sun-dried mixture of cow or buffalo dung and straw, as cooking fuel was associated with respiratory disease (adjusted OR = 2.69, 95% confidence interval [CI] = 1.37-5.31, P = 0.004), as was overcrowding in the bedroom (adjusted OR = 1.25 for each additional person, 95% CI = 1.11-1.41, P = 0.001). Age, weight, gender, family income, and household structure were not associated with disease. Use of dung cakes as cooking fuel and overcrowding in the bedroom increased the risk of respiratory disease. Interventions to modify oven design or install chimneys and, where feasible, to reduce the number of people sleeping together should be considered.

We present the results of the investigation of an epidemic outbreak of Mycoplasma pneumoniae infection which affected 95 schoolchildren from certain village in Catalonia. The investigation took an epidemiological, clinical and microbiological approach, detecting by capture enzyme-immunoassay technique the presence of IgM antibodies against M. pneumoniae. All cases occurred over a 9 week period. The attack rate in children under five was 18% and 8.2% in those from 5-14 years. The age mean and standard deviation of the cases was 5.2 +/- 3.5 years, the range being from 9 months to 14 years. Cough was the most common clinical manifestation (87.4%), followed by fever (67.4%), asthenia (21.1%), abdominal pain (18.9%), vomiting (13.7%), earache (8.4%) and sore throat (6.3%). There was no significant difference in the distribution of symptoms according to age groups. IgM anti M. pneumoniae was positive in 36 (37.9%) of the samples analysed. Treatment chosen in most cases (90) was eritromicin and there was a correct evolution in all cases except for two clinical and radiological recurrences. Hospitalization was only necessary in 5 cases. The present findings are important to emphasize the high incidence of M. pneumoniae respiratory disease in children under 5, and suggests that with respiratory processes affecting very young children, a possible Mycoplasma pneumoniae infection should also be considered and the necessary action taken in the form of early and appropriate treatment.

The objective of this investigation was to determine whether Chlamydia pneumoniae was involved in an outbreak of respiratory disease among military recruits, 92 patients (average age 20.1 years) were included in the study if they had a sore throat or cough for more than 1 week. In addition to sore throat and cough, fatigue, headache, dyspnoea and vertigo were the most frequent symptoms. The patients received standard treatment with 100 mg of doxycycline b.i.d. for 14 days. In 38.8% of cases symptoms were alleviated after 1-2 weeks of treatment, and in 22.4% of cases after 2-3 weeks of treatment. Pretreatment throat washings and sera were sampled for Chlamydia. Sera were drawn for Chlamydia, Mycoplasma and adenovirus serology. Cell culture (Hep-2) and 3 different serological methods-microimmunofluorescence (MIF), enzyme immunoassay with a recombinant glycoconjugate antigen (r-EIA) and immunoperoxidase assay (IPA)-were used. Cell culture was found to have too low a sensitivity to be of diagnostic value. Acute infection was demonstrated in 13% by MIF IgM and in an additional 21% by MIF IgG (titre rises). Enzyme immunoassay IgM was found in 17% and IPA IgM in 19% of individuals without MIF IgM antibodies. Microimmunofluorescence was found to be the most useful test for serodiagnosis. The combination of serological methods showed that 40 out of 52 (76.9%) had an acute infection with possible chlamydial aetiology. In conclusion, methodological improvements are necessary for the aetiological diagnosis of chlamydial respiratory infections.

The authors investigated the health effects of occupational exposures to vehicle emissions in 745 bus drivers, conductors, and taxi drivers, compared with 532 unexposed controls, in Shanghai. Logistic regression and general linear models were used to examine the relationship between exposure and respiratory illness. Results showed that the prevalences of some respiratory symptoms and chronic respiratory diseases were significantly higher (p < 0.05) in the exposed group than in the controls. The adjusted odds ratios for throat pain, phlegm, chronic rhinitis, and chronic pharyngitis were 1.95 (95% CI 1.55-2.46), 3.90 (95% CI 2.61-5.81), 1.96 (95% CI 1.11-3.46), and 4.19 (95% CI 2.49-7.06), respectively. Also, there were exposure time response relationships for the prevalences of phlegm and chronic respiratory disease. Pulmonary function and blood lead levels were not significantly correlated with exposure status. The results suggest that occupational exposure to vehicle emissions may induce detectable adverse health effects.
