Pulmonary sequestration is a relatively rare condition in which a part of lung tissue has no or only a secondary connection with the tracheobronchial tree. Blood supply comes from the aorta in anomalous branches. Sequestrations may be intra- or extralobar. Gerle et al. include both types in the general term congenital bronchopulmonary foregut malformation. Two surgically confirmed observations of bilateral intralobar pulmonary sequestrations are reported. The clinical features are recurrent respiratory infections with cough, fever and purulent sputum. X-rays only show nonspecific alterations. Chronic changes in the lower lobes should draw attention to pulmonary sequestration. Thoracic aortography is the procedure of choice in establishing the diagnosis and should always be carried out preoperatively. Segmental resection or lobectomy is the indicated treatment.

Thoracic duct end pressures have been measured in a conscious patient undergoing cannulation in an attempt to remove serum blocking activity. Pressures were measured during rest, coughing, straining and laughing during the last-mentioned activity pressures of the order of 85 mm Hg were recorded. It is suggested that formal ligation of the cannula at the termination of treatment.

The relative responsitivy of nine expirographic and airway indices to antitussive therapy was studied in a randomized double-blind trial in which 60 adults without bronchopulmonary disorders, but suffering from common colds, were given oral doses of five drug formulations or placebo during their initial 48 h of symptoms. Thoracic gas volume (Vtg), nasal (Rn), lower (Ra), total t[Rn + Ra]) and specific (sRa) airway resistances were determined plethysmographically; forced vital capacity (FVC), forced expiratory volume for the first second (FEV1.0) and maximal mid-expiratory flow rate (MMEFR) were recorded spirometrically. Cough pressure at peak flow furnished an index of cough (CI). The measurements were made at baseline and for 4 h after drug; medication was continued for two additional doses and the indices determined again the following morning. Abnormal control means were noted for Rn and [Rn + Ra] (90.8%), cough resistance (83.3%), MMEFR (58.3%), Ra and sRa (30.0%), but less ofter for FEV1.0, Vtg and FVC (6.6, 5.1 and 0.0%, respectively). Nasal and total airways flow resistance means were as sensitive to active therapy and in discriminating the relative worth of medication as direct CI values, Ra and sRa were less reliable, and the three spirometric functions were the lease responsive. This ranking was consistent with the common central airways location of subepithelial receptors responsible for cough and the associated reflex bronchoconstriction. The greatest changes in cough resistance followed treatment with the most significant activity in the nasal, as well as the lower tract, component of total airway resistance.

A new method for objective assessment of cough under normal or pathological conditions is described. Thoracic coughing can be discriminated from any other pressure wave because of its relatively high frequency. This method was applied in a double blind crossover trial in 18 patients with respiratory disease.

A case of Kaposi syndrome is described in a 28-year-old heterosexual male with acquired immunodeficiency syndrome. The disease began clinically with pulmonary disease, without mucocutaneous lesions. This form of presentation is extremely infrequent and has not been described in non-homosexual subjects. Clinical manifestations were fever, cough and dyspnea. Thoracic radiography observed a perihilar interstitial pattern which evolved to a bilateral nodular pattern with perihilar adenopathy. There was endobronchial disease, however pulmonary biopsy was required for diagnosis. Complete tumoral remission was achieved with adriamycin, bleomycin and vincristine.

A health survey was carried out among 8259 second- and fifth-grade schoolchildren living in three towns along the Israeli coast. The schoolchildren performed the following pulmonary function tests: forced vital capacity, forced expiratory volume in 1 sec, and peak expiratory flow, their parents filled out an American Thoracic Society-National Heart and Lung Institute health questionnaire. The aim of the survey was to study the impact of environmental and home exposures on the prevalence of respiratory conditions and on pulmonary function tests among Israeli schoolchildren. The health effects of exposure to passive smoking are discussed in detail. A trend of a higher frequency of reported respiratory conditions was found among schoolchildren whose fathers or mothers are smokers compared with children whose parents do not smoke. A statistically significant excess between 1.4% (for wheezing without cold) and 4.7% (for cough with cold) was found for children of smoking fathers; the excess for children of smoking mothers was between 1.6% (for wheezing with cold) and 3.6% (for cough with cold) compared with children of nonsmokers. A gradual excess in symptoms was found among children with none, one, and two smoking parents. Relative risks were found to be between 1.13 (for bronchitis) and 1.28 (for wheezing without cold) for children of smoking fathers, and between 1.24 (for asthma) and 1.41 (for cough with sputum) for children of smoking mothers, compared with 1.00 for children of nonsmokers. There was no consistent trend of reduced pulmonary function tests among children of smokers compared with nonsmokers' children.

This study was carried out in the framework of a health monitoring system set up in the vicinity of a 1400 megawatt coal-fired power plant in Israel. Second- and fifth-grade school children were followed up every 3 years; they performed pulmonary function tests (PFT), and their parents filled out American Thoracic Society-National Heart and Lung Institute health questionnaires. Among the cohort of second graders (in 1983) living in the area expected to be most polluted, a significant increase in the prevalence of part of the respiratory symptoms (such as cough and sputum, wheezing with and without cold and wheezing accompanied by shortness of breath) was evident in 1986. The prevalence of asthma among fifth graders in this area doubled (p = 0.0273) compared with prevalence when they were second graders. Among the children from the older cohort (fifth graders in 1983) living in this community, a similar although milder trend could be observed, especially in regard to an increased prevalence of asthma in 1986 compared with 1983 (13.9% versus 8.1%). Annual increases in PFT in the four groups of children (boys and girls from both cohorts) were found to be higher in the community expected to be polluted (especially in the younger cohort) compared with the two other communities. The discrepancy between the increased prevalence of respiratory symptoms and diseases and the higher annual increase in PFT among children from the expected more polluted community may be partly attributable to differential annual increase in height and to different distribution of background variables (such as socioeconomic status, passive smoking, heating, and respiratory diseases among parents) in the three communities.

Standardized French and English versions of the American Thoracic Society (ATS) respiratory disease questionnaire were administered to 204 English-speaking and 406 French-speaking male blue-collar aviation workers unexposed to occupational respiratory hazards. After adjusting for smoking status, age, years of education, foreign birth and maternal language other than French or English, no significant differences between the two questionnaires were found for response rates to usual cough, usual phlegm, mild or moderate dyspnoea, and chronic bronchitis. French-speaking workers reported significantly less wheeze with colds (OR = 0.60, p less than 0.02) and wheeze apart from colds (OR = 0.55, p less than 0.05) than the English-speaking group, but, the occurrence of wheeze on most days or nights was similar for both groups (OR = 1.02, NS). For 66 bilingual workers who completed both French and English questionnaires at a time interval of approximately two months, highly consistent results were found for sociodemographic data, smoking habits, cough, phlegm, breathlessness and chronic bronchitis, but not for wheeze with or apart from colds (agreement less than 90%; Kappa less than 0.50). These results reflect the difficulties in translating the concept of 'wheeze' from English to French. We conclude that most symptoms elicited by the French questionnaire may be generalized to English-speaking populations, but that questions pertaining to wheeze on most days or nights may be preferable to other questions concerning wheeze.

Eighteen dogs with chronic bronchitis were studied using physiologic, radiologic, microbiologic, and pathologic techniques. Twelve of these dogs were evaluated before and after two weeks of oral bronchodilator administration. Thoracic radiographs, tidal breathing flow-volume loops, radioaerosol ventilation scans, airway appearance at bronchoscopy, and airway pathology were abnormal in the majority of dogs studied. There was a significant relationship between abnormal ventilation scans and abnormal results for PaO2 and end-tidal airflow. Bronchoscopy revealed excessive mucus and inflammation of airway mucosa in all 16 dogs undergoing this procedure. Endoscopically obtained aerobic bacterial cultures grew mixed bacterial flora in only three dogs. Increased numbers of neutrophils in 14 dogs were detected by airway lavage cytology. A large number of eosinophils were seen in airway lavages obtained from two dogs; these two dogs also had evidence for eosinophilic bronchitis on endobronchial biopsy. Oral bronchodilator administration resulted in clinical and expiratory airflow improvements in most dogs, but had no effect on PaO2 or on the radioaerosol-scan abnormalities. The presence of both the physiologic and pathologic airway abnormalities of chronic bronchitis in dogs presented to a veterinary hospital with chronic unexplained cough was confirmed, suggesting that aerobic bacteria do not play an etiologic role in most cases.

A total of 1,566 children the area of Valencia (Spain), of both sexes and aged 7 to 14 received an epidemiological questionnaire recommended by the American Thoracic Society. Antecedents of asthma were recorded in 79 cases (5%), with a predominance among males; 73.3% of these children presented their first crisis before age three. Eighty-seven children were habitual smokers (5.6%), again with a predominance among males-most of these children being between 13 and 14 years old. A family history of smoking was observed in 82.8% of the children who were habitual smokers. A greater predominance of smoking mothers was observed at higher socio-economical levels--with no significant differences between parents. The incidence of respiratory pathology (cough and antecedents of bronchitis) was higher among children whose mothers (or both parents) were smokers. On comparing the two areas of the city with the greatest difference in air pollution level, no significant differences were observed in respiratory morbidity among the child population.
