Respiratory symptoms and personal history of allergy were examined in 1659 children, including the entire elementary school population of four villages of the Belgian Ardennes. Levels of atmospheric pollution were monitored during the survey and proved to be very low. It is suggested that socio-economic factors produce a small increase in respiratory symptoms, particularly in cough symptoms. A personal history of eczema and of hay fever was highly associated with dyspnea and wheezing.

There are three steps in establishing the diagnosis of asthma in a child presenting with recurrent wheezing or recurrent coughing. The first is to decide whether the symptoms are due to asthma, the second is to consider possible aetiological factors--mainly to reassure the parents that there is nothing particular in this area that need be done--and the third is to determine what is the pattern of airways obstruction. Is it purely episodic or alternatively, are there periods where it persits? In younger children, clinical evidence alone is all that is available to decide whether the respiratory symptoms are due to asthma, and to determine its pattern. In older children, pulmonary function tests are very helpful.

Stage I sarcoidosis usually presents with roentgenographic evidence of hilar adenopathy and the patients are totally asymptomatic. However, five patients were studied at the Mayo Clinic who had stage I sarcoidosis associated with obstructive disease of the airways. Four of the five presented with dyspnea, wheezing, and cough, and they were found to have expiratory slowing on physical examination. One patient was asymptomatic and her physical examination was normal. On pulmonary function testing, she had a decrease in maximal midexpiratory flow, and at fiberoptic bronchoscopy, mucosal changes consistent with noncaseating granuloma of sarcoidosis were seen. All five patients had the classic roentgenographic appearance of sarcoidosis, with hilar and right paratracheal adenopathy. Endobronchial involvement is well known in sarcoidosis, but its significance in stage I disease has not been emphasized in the literature. An awareness of this possibility is important because it may be an indication for bronchoscopy and mucosal biopsy in the patient with stage I sarcoidosis, particularly when the patient presents with dyspnea, wheezing, and cough. Also, corticosteroid, therapy may be indicated in selected patients with stage I sarcoidosis.

Six patients with chronic cough, without history of dyspnea or wheezing, had normal base-line spirometry but hyper-reactive airways, as demonstrated with methacholine. Maintenance therapy with bronchodilators promptly eliminated the cough in all patients. Three to 12 months later therapy was discontinued for three days, cough returned, and detailed pulmonary-function studies were carried out. Again, base-line values were normal, but after methacholine one-second forced expiratory volume decreased an average of 40 per cent in the patients as compared to 30 per cent in normal controls (P less than 0.001). The point of identical flow was increased by methacholine to 43.5 per cent of vital capacity in the patients, as compared to 6 per cent in normal controls (P less than 0.001), and the alveolar plateau was 4.8 deltaN2 per liter, as compared to 1.4 in normal controls (P less than 0.01). Specific airway conductance was lowered in patients and controls, but the post-methacholine value was significantly lower in the patients. On the basis of their persistently hyper-reactive airways, inducible diffuse airway bronchoconstriction and excellent response to bronchodilator therapy, these patients appear to have a variant form of asthma in which the only presenting symptom is cough.

Cromolyn sodium was administered by inhalation four times a day to 53 severely asthmatic children for periods ranging from 10 to 43 months. The patients were seen at follow-up vists at least once a month through the entire study period. At the cut-off point of the study cromolyn sodium had been effective in controlling asthma by reducing the level of asthma symptoms, such as coughing, wheezing, sleep disturbance and sputum output. In addition there was a reduction in the patients' requirements for concomitant anti-asthma medications (including corticosteroids) and the number of hospitalizations and school absences.

Cardiac and pulmonary disease are so closely interrelated that it is often difficult to determine in young infants which is the primary offender. As illustrated in these case reports, failure to recognize the true nature of the disease process may lead to unnecessary procedures and delays which can be life-threatening. Statistically, the wheezing infant very likely is suffering from primary pulmonary disease; however, congenital cardiac abnormalities can cause pulmonary symptoms which completely dominate the clinical picture and lead to erroneous diagnoses. Although rare, the basis of cough and wheezing may be a vascular ring which encircles and compresses the trachea. Lesions associated with large left-to-right shunts, such as ventricular septal defect and patent ductus arteriosus, also can cause cough and wheezing because of bronchial compression by a large tense pulmonary artery and a distended left atrium. These same lesions also produce isolated left ventricular failure with pulmonary venous congestion and episodes of cough and wheezing. Anomalous pulmonary venour return, cor triatriatum, supravalvular mitral ring, or mitral stenosis are other lesions which can cause cough and wheezing secondary to pulmonary venous obstruction.

Progressively severe sneezing, rhinorrhea, cough, wheezing, and dyspnea developed in a spray-painter, apparently in relation to exposure to a particular spray paint. A monitoring of exposure at work revealed the development of symptoms and a decrease in peak flow rates. Subsequent challenges in the laboratory performed under conditions resembling occupational exposure resulted in dual asthmatic responses on exposure to the whole paint (98 per cent methyl methacrylate emulsion and 2 per cent dimethyl ethanolamine solution) and to dimethyl ethanolamine solution (2 per cent) alone. Water, methyl methacrylate emulsion, and 1,4 dioxane (0.6 per cent) used as a thinner in the dimethyl ethanolamine did not produce a response in the airways. Allergy skin tests with dimethyl ethanolamine and a mixture of dimethyl ethanolamine and human serum albumin were negative. To our knowledge, this is the first report of asthma and/or rhinitis induced specifically by dimethyl ethanolamine. The mechanism of the specific reactivity is not known.

Respiratory symptoms, disease and lung function were studied in 376 families with 816 children who participated in a survey in three USA towns. Parental smoking had no effect on children's symptoms and lung function. Also, there was no evidence that passive smoking affected either lung function or symptoms of adults. There was no association between prevalence of self-reported cough and/or phlegm in parents and their children. There was a highly significant association between the prevalence of wheeze in parents and their younger children, for whom parents reported this symptom. Wheeze in children was also significantly associated with a parental history of asthma, and lung function was lower in children with a family history of asthma. Even after accounting for height, weight, age, sex and race, children's lung function correlated significantly with parents' lung function. However, the contribution of familial factors (i.e., parents' lung function, smoking, and history of asthma) to children's lung function is small compared to the effects of height, weight and age.

In a prospective study at two medical centers, 42 consecutive patients with suspected sarcoidosis underwent transbronchial lung biopsy during fiberoptic bronchoscopy. Transbronchial biopsy revealed noncaseating granulomas in 24 of the 38 cases (63%) in which adequate tissue was obtained. Special stains and cultures for acid-fast bacilli and fungi were negative, and sarcoidosis was subsequently diagnosed in all 42 cases. Positive biopsies were obtained in 11 of 20 patients with radiographic stage I disease, in 11 of 15 with stage II disease, and in 2 of 3 with stage III disease. There was a higher probability of a positive biopsy in patients with high symptom scores for cough, wheezing, and dyspnea, and in those with a vital capacity of less than 80% of predicted. The only complication was one small pneumothorax, which spontaneously resolved. Transbronchial lung biopsy is an attractive initial procedure for obtaining histologic confirmation of sarcoidosis.

The incidence of respiratory symptoms caused by grain dust during harvesting was surveyed in a group of Lincolnshire farmers. A quarter complained of respiratory distress after working on combine harvesters or near grain driers and elevators, with cough, wheezing, and breathlessness, sometimes so severe as to prevent work. The airborne dust around combine harvesters contained up to 200 million fungus spores/m3 air with Cladosporium predominant while drivers were exposed to up to 20 million spores/m3 air. Verticillium/Paecilomyces type spores, mostly from Verticillium lecanii, Aphanocladium album, and Paecilomyces bacillosporus, were abundant in the dust. Extracts of these species produced immediate weal reactions in skin tests, precipitin reactions with sera, and rapid decreases in FEV1 when inhaled by affected workers. There was no delayed reactions. Results suggest type I immediate hypersensitivity to the spores although the physical effect of a heavy dust deposit could be important. Drivers could be protected by cabs ventilated with filtered air.
