Because a number of "early tests" may now be used to measure abnormalities of lung function in cigarette smokers with normal airflow rates, we evaluated the symptoms of cough, sputum, wheezing, and shortness of breath in 60 nonsmokers and 49 smokers to determine whether these symptoms correlated with measurements of lung function that are believed to be altered by mild obstruction. One or more symptoms were present in 5 per cent of the nonsmokers and 90 per cent of the smokers. Individual symptoms, sums of symptoms (symptoms score), and various combinations of symptoms correlated poorly or not at all to measured values for dynamic lung compliance, closing volume, closing capacity, slope of Phase III, and helium flow-volume curves. The symptoms score correlated negatively (P less than 0.05) with forced maximal expiratory flow at 50 per cent of vital capacity. Inasmuch as the serious consequences of chronic airway obstruction are related to abnormalities of lung function, it is likely the function tests will prove more useful than symptoms to reveal smokers at risk to develop chronic obstructive pulmonary disease. Symptoms cannot be used to detect smokers who are liable to have functional abnormalities suggestive of mild peripheral airway obstruction.

Mucoepidermoid carcinoma of the trachea is rare. Its occurence in a 14-year-old boy is reported here. This case illustrates the typical course of tracheal tumors with clinical manifestations of cough, wheezing, and hemoptysis, the intially reported normal chest roentgenogram, and the common failure to diagnose tracheal tumor for several months. Early use of tomographic studies and bronchoscopic examination in any person with recent onset of airway obstruction unresponsive to bronchodilator therapy is recommended.

A retrospective analysis of 50 patients who had been observed to aspirate gastric contents was performed to define better the course of patients with this syndrome. The patients invariably had a disturbance of consciousness, most commonly due to sedative drug overdose or general anesthesia. The onset of clinical signs occurred prompty after aspiration and tended to be similar in all patients, irrespective of their subsequent course or outcome. These findings usually included fever, tachypnea, diffuse rales, and serious hypoxemia. Cough, cyanosis, wheezing, and apnea were each seen in approximately one third of the cases. Apena, shock, and early severe hypoxemia were particularly ominous events. Initial roentgenograms revealed diffuse or localized alveolar infiltrates, which progressed during the next 24 to 36 hours. Subsequent clinical courses followed 3 patterns: 12 per cent of the patients died shortly after aspiration; 62 per cent had rapid clinical and radiologic improvement, with clearing, on average, within 4.5 days; 26 per cent demonstrated rapid improvement, but then had clinical and radiographic progression associated with recovery of bacterial pathogens from the sputum and a fatal outcome in more than 60 per cent. Treatment from the outset by adrenocortical steroids or antimicrobial agents had no demonstrable effect on the outcome. The clinical features of aspiration of gastric contents are characteristic and distinguish it from other forms of aspiration-related lung disease.

For years, halothane has been the anesthetic agent of choice for patients with chronic obstructive pulmonary disease (COPD) and reversible airway disease (asthma). Enflurane was compared with halothane in 100 patients with COPD substantiated by spirometry and history. Intraoperative and postoperative complications in each relatively homogenous 50-patient group were assessed. Spirometry, blood gases, chest x-rays, incidence of complications involving secretions, coughing, wheezing, and cardiovascular problems were similar in both groups. Enflurane appears to be equivalent to halothane as an anesthetic in such patients.

The results of a questionnaire concerning respiratory symptoms in Dunedin public servants have been reported earlier (de Hamel, O'Donnell, 1972). This report is of the results of spirometry in the same population. Fifty-five percent of 1079 men and 59 percent of the 310 women with normal mass miniature chest x-rays showed an FEV 1.0 below the predicted value, but in only 9 percent of each sex was the FEV 1.0 less than 80 percent of predicted. Bronchitic symptoms and a history of regular cigarette smoking were associated with an impaired FEV 1.0. The FEV 1.0 was normal in many giving a history of the bronchitic symptoms cough, phelgm or wheezing. The FEV 1.0 of overweight men was not significantly different from the other men. Attention is drawn to the high frequency of chronic bronchitis in the population and the correlation of this with moderate and heavy cigarette smoking. The questionnaire disclosed more abnormality within the population than did the spirometrey. They may complement one another when effort is being directed at health education.

Although wheezing is believed to be a cardinal manifestation of asthma, some patients with this disorder may not present with wheezing, but rather with either exertional dyspnea or cough. In 14 such patients with dyspnea, there was peripheral airway dysfunction with markedly elevated residual volumes, frequency dependence of dynamic compliance and depressed flow rates in the middle-vital-capacity range, whereas specific conductance and one-second forced expiratory volumes were normal. Circumstantial evidence suggests that mucosal edema or mucous secretions may have been responsible. In seven patients with cough, studies revealed a more severe obstructive pattern that appeared to be the result of increased large-airway resistance, and the patients' response to isoproterenol indicated that contraction of bronchial smooth muscle may have been principally responsible. Thus, intermittent episodes of cough or breathlessness may represent variant aspects of asthmatic attacks.

Subjects residing in the warm, dry climate of Tucson, Arizona showed the same relationship of productive cough to smoking as noted elsewhere, but they less regularly reported seasonal or diurnal exacerbations of their symptoms and they less regularly reported phlegm production along with chronic cough. In this locale, even nonchronic dry cough was associated with an increased frequency of other respiratory symptoms and of ventilatory impairment. In comparing characteristics of subjects with a clinical diagnosis of chronic bronchitis with characteristics of subjects who had only questionnaire-detected chronic productive cough, it was found that smoking habits were more closely related to the presence of chronic cough than to the clinical diagnosis. The clinical diagnosis was associated with other features, such as wheezing, at least as often as with productive cough. This was especially true in children, in whom a suprisingly high prevalence of both chronic cough and clinically confirmed chronic bronchitis was noted. These observations led to questions concerning the appropriateness of using a common clinical term such as chronic bronchitis to describe subjects whose only known abnormality is an affirmative answer to a direct question concerning phlegm production.

Allergic bronchopulmonary aspergillosis is being recognized with increasing frequency in the United States. The characteristics of the disease are recurrent pyrexia, cough, wheezing, sputum plugs containing aspergilli, fleeting pulmonary infiltrates, eosinophilia, dual skin reactions (immediate and late), and antibodies to the fungus in the blood. The pathogenetic mechanism is believed to involve type I and type III hypersensitivity reactions. Adrenal corticosteroids are effective in treating this condition.

This was a double-blind, randomised evaluation of the efficacy and safety of Zaditen in comparison with placebo in infants and young children (aged 6-36 months). These children either had (i) at least 2 episodes of wheezing over 8 weeks, or (ii) persistent wheeze over 4 weeks, prior to entering into the study. In the doctor's opinion, the group treated with Zaditen had more improvement in symptomatology (p < 0.05). They were more likely to have reduced or discontinued bronchodilators. They showed trends of improvement of symptom scores in night cough, wheeze and sputum production. These differences, however, did not reach statistical significance. There were no major adverse reaction of note.

Foreign bodies aspirated into respiratory tract may produce severe lung damage and threaten life. We have analysed retrospectively symptoms, physical findings, chest roentgenograms and bronchoscopy reports in 20 children with foreign body aspiration. Boys dominated in this group. Foreign body aspiration often accompanied by coughing, wheezing and vomiting. In chest X-ray examination it was revealed unilateral body trapping and obstructive emphysema. Foreign body aspiration should be considered in children with prolonged respiratory tract problems even when no adequate history is present and with negative chest roentgenograms.
