Intravenous salbutamool or aminophylline was administered under double-blind conditions to 20 asthmatic patients presenting with severe dyspnoea and needing urgent treatment with bronchodilators. Ten patients received salbutamol and ten patients received aminophylline. Objective measurements showing improvement were recorded in nineteen patients. A greater response was produced by salbutamol although this failed to reach statistical significance. Neither drug affected pulse or blood pressure. It is suggested that intravenous salbutamol is an effective bronchodialtor in the treatment of acute exacerbation of asthma or bronchitis.

356 male patients (non-suffering from the lungs, recidivity-bronchitis or chronic bronchitis) were interrogated about the presence of difficulty in breathing that depends on burden and weather, and these patients were investigated for detection of a bronchial obstruction and a bronchial hyperreactivity. With the increased degree of a manifest bronchial obstruction a high-significant increase in frequency of load-dyspnea was demonstrated. On the other hand a significant increase of difficulty in breathing that depends on weather can be obtained only in patients with bronchial hyperreactivity. To estimate more differentiated the difficulty in breathing about which the patients pointed out, an investigation by means of the acetylcholine test is necessary.

The results of intermittent normobaric hypoxytherapy in 42 patients with bronchial asthma (BA) and 14 patients with chronic obstructive bronchitis (COB) are analyzed. The positive effect is obtained in 76% of patients with BA and 92.8% of patients with COB. In the group of patients with BA the best effect was achieved for atopic form of BA--in 90% of patients, the effect was less pronounced for infection-allergic form--in 73.9% and for mixed form of BA--in 66.7%. In the process of treatment the attacks of asphyxia disappeared or became more occasional in 60.7% of patients; in 32.1% the attacks were more easily arrested or stopped independently; 33.8% of patients decreased doses of constantly taken drugs; in 33% cough ceased or decreased, sputum became to expectorate better; in 41% of patients dyspnea disappeared and considerably decreased. Improvement of the state in 54% of patients was retained for one year and more, in 29%--for 6 months, in 16.6%--for 3-4 months. The course of treatment consisted of 20-25 sessions. The patients breathed in hypoxic gas mixture containing 10% of oxygen (HGM-10) under intermittent conditions alternating with respiration of free air.

A 44-year-old male was hospitalized due to dyspnea and persistent cough with copious sputum (about 100 ml/day). Chest radiograph on admission showed hyperinflation and fine nodular shadows throughout both lungs, as well as a tram line appearance in the right lower lung field which suggested thickening of bronchial walls. Pulmonary function tests demonstrated moderate to severe reduction of %VC, FEV1.0 and PaO2. Fiberoptic bronchoscopy revealed inflammatory change in the walls of proximal bronchi. Although his dyspnea resolved rapidly, productive cough and impaired lung function were persistent and improved very slowly over the one-month-period following admission. After resolution, similar symptoms were provoked again 5 to 6 hours after returning to his home, suggesting the recurrence of hypersensitivity pneumonitis. Open lung biopsy was performed for the differential diagnosis of hypersensitivity, diffuse panbronchiolitis, and bronchial asthma, because neither transbronchial lung biopsy nor broncho-alveolar lavage was diagnostic. Histopathology of the open lung biopsy specimens revealed marked desquamation of bronchiolar epithelium in addition to bronchiolo-alveolitis with epithelial granulomas, consistent with hypersensitivity pneumonitis. Copious sputum is a very uncommon clinical feature in hypersensitivity pneumonitis. We consider that the large volume of airway fluid was caused by epithelial ulceration of bronchioles and catarrhal bronchitis associated with hypersensitivity pneumonitis.

Respiratory symptoms, spirometry, and transfer factor were measured in 208 non-smoking Western Australian underground goldminers (mean age 32) to identify the presence of respiratory abnormalities resulting from underground work. These subjects were part of a larger group of 771 subjects attending for statutory periodic chest x ray examinations in the industry. They had worked underground for a median of three years. The prevalence odds ratios of bronchitis, dyspnoea, wheeze, and asthma all tended to be related to duration of underground employment, even after adjusting for age, those for wheeze and asthma reaching statistical significance. After adjusting for age and height the duration of employment also had a significant effect on TL/VA but not on FEV1, FVC, or TL. These changes are consistent with the presence of airway narrowing and non-specific lung fibrosis or emphysema in non-smoking underground goldminers.

Purulent bronchitis was identified in 19 of 422 patients undergoing fiberoptic bronchoscopy during a 32-month period because of suspicion of an opportunistic lung infection complicating acquired immunodeficiency syndrome or human immunodeficiency virus infection. Five patients had Pneumocystis carinii pneumonia, but other opportunistic lung infections were excluded in the remaining 14 patients. Characteristics of these 14 patients included fever (greater than 38.3 degrees C), cough, and dyspnea in 14 of 14 patients; purulence of expectorated sputum (11/14); and widened alveolar-arterial oxygen gradient (13/14). Rapid (2 +/- 1.4 days) clinical response (defervescence and resolution of pulmonary symptoms) occurred with antibiotic therapy in 10 of 14 patients. In three patients, there was no improvement, and adult respiratory distress syndrome developed. Bacterial isolates from bronchoalveolar lavage included Streptococcus viridans (n = 12), Haemophilus influenzae (n = 7), Staphylococcus aureus (n = 3). Roentgenographic features of bronchiectasis were present in seven patients. Differential cell counts revealed greater than 50% neutrophils in the bronchial washings of all patients with purulent bronchitis. Neutrophil percentages in bronchoalveolar lavage were as follows: patient with purulent bronchitis without P carinii pneumonia (n = 14), 54.53% +/- 29.18%; patients with purulent bronchitis and concomitant P carinii pneumonia (n = 5), 62% +/- 31.9%. In a control group of 17 patients with P carinii pneumonia who did not have purulent bronchitis, the neutrophil percentage was 6.8% +/- 6.17% (p = less than 0.00001, t-test). Purulent bronchitis appears to be a distinct, treatable entity in patients with HIV infection and may accompany bacterial pneumonia, bronchiectasis, and P carinii pneumonia.

An enquiry was made to determine the prevalence of asthma in adolescents and was achieved using a questionnaire which was filled in by the pupils in secondary schools in Rabat. The sample was determined by a systematic poll of 1,616 pupils of whom 1,464 (90.6%) replied. 88 pupils (6.0%) replied in the affirmative to the question "Have you ever had whistling noises in the chest?", 78 (5.3%) to the question "Have you ever had a sensation of respiratory difficulty or suffocation with a whistling noise in the chest?", 48 (3.3%) to the question "Have you ever had asthma?" and 36 (2.5%) to all 3 questions and 114 (7.8%) to one or other of the questions. After a detailed questionnaire had been carried out on 110 of 114 pupils the diagnosis of asthma was confirmed in 50, which gives an estimation of the accumulative prevalence of 3.4% +/- 0.9%. This prevalence is higher amongst the oldest children in the family (26 out of 349, 7.4%) compared to the birth order of the other brothers and sisters (24 out of 1,112, 2.2%) (p less than 0.001). Pupils from higher social backgrounds (22 out of 256, 8.6% against 28 out of 1,208, 2.3% from more average or more poor social backgrounds, p less than 0.01). A past family history of asthma were more often noted in asthmatics (38 out of 50, 76%) than in non-asthmatics (406 out of 414, 28.7%) p less than 0.001). In the same way cough and phlegm and episodes of bronchitis occurring in autumn and winter and breathlessness on effort are more frequent in asthmatics; 20 out of 50 (40%) against 318 out of 1,414 (22.5%) for the cough (p less than 0.01), 12 out of 50 (24%) against 157 out of 1,414 (11.1%) for phlegm (p less than 0.01), 31 out of 50 (62%) against 337 out of 1,414 (23.8%) for episodes of bronchitis (p less than 0.001) and 15 out of 50 (30%) against 219 out of 1,414 (15.5%) for breathlessness on effort (p less than 0.001). Besides this we have noticed a slight predominance of asthma in boys compared to girls but the difference is not significant.

The effectivity of recently introduced beta adrenergic agents in the USA prompted physicians to reevaluate the usefulness of theophylline having been used solely as a bronchodilator in the treatment of obstructive respiratory tract diseases. As part of a complex therapy applied in different diseases (acute asthmatic attacks, chronic asthma, acute exacerbation, and long-term treatment of obstructive bronchitis) theophylline is still a drug of value. The risk of toxicity can be reduced to a minimum. In the prevention of certain symptoms (e.g. nocturnal dyspnoea of asthmatics) (slow release) theophylline preparations proved to be the most advantageous. In aged patients technical difficulties limit the use of inhalation therapy, the oral applicability of theophylline is a further advantage of this product.

16 silicone stents and 9 expandable metallic stents (Strecker-stents) were implanted in 22 patients (16 x tumors of central bronchial tree, 6 x stenosis of benign conditions). The silicone stents were mainly implanted in the trachea and main bronchi, the metallic stents in lobar bronchi. In all cases we succeeded in implantation without complications. With both stent models an immediate relief of dyspnea and respiratory failure was achieved in all cases. The average period of follow-up is 65 days, the longest 105 days (silicone stents) respectively 306 days (metallic stents). All stents were tolerated well besides one with a feeling of intrathoracic pressure. Complications were dislocation (1 x), occlusive tumor growth (1 x), granulations (1 x), suppurative bronchitis (2 x), growth of tissue through the wall of metallic stents (1 x) and restenosis by indurated secretions (2 x). Though the long term results were well with different types of stents, which are available today, the expandable stent woven of metallic wire, seems to fit best to clinical needs.

A 76-year-old man was referred to our hospital with complaints of productive cough, dyspnea and peripheral cyanosis. The chest X-ray film indicated the pulmonary emphysema and acute bronchitis, but no abnormal intracardiac calcification. The electrocardiogram revealed a peaked P-wave, complete left bundle branch block, and ventricular premature contraction. Chest tomography demonstrated abnormal intracardiac calcium deposition in the right heart region. Two-dimensional echocardiography revealed the tricuspid annular calcification in the postero-lateral portion, showing a synchronous movement with tricuspid annular motion throughout the cardiac cycle. The size of calcification was 10 x 14 mm. The tricuspid valve showed no significant regurgitation. Left ventricular dilatation, associated with mild mitral regurgitation and impairment of systolic function (EF = 49%) was revealed by echocardiography. Serum examination revealed positive in Wassermann reaction. This case of tricuspid annular calcification might be caused by atherosclerotic degenerative change related to the aging process, or by an unknown mechanism related to pulmonary emphysema.
