[Physical training as a means of clinical rehabilitation in internal diseases in aging. 3. Lung diseases].

Adequate physical training among healthy persons of all age groups promotes adaptability of the respective organs. A similar effect can be shown among patients provided that contraindications are taken into account. Physical training as treatment for heart and circulation--diseases is widely known. In the case of lung-diseases similar experiences are still lacking. In this paper indications, contraindications and the effects of an adequate training in combination with medical therapy in chronic pulmonary diseases are reported. 1. Our investigations show a significant improvement of the cardiopulmonary function among patients with chronic obstructive bronchitis when treated with combined therapy, as compared to those treated with drugs only. 2. Among patients with asthma bronchiale, after diseases of the pleura, after pneumonia and tuberculosis or before and after lung operations an adequate physical training in addition to medical therapy for improvement of the cardiopulmonary function is recommended also.

Tucson epidemiologic study of obstructive lung diseases. II: Effects of in-migration factors on the prevalence of obstructive lung diseases.

The effects of in-migration factors on respiratory symptoms, chronic health problems, and lung function were examined in the stratified Tucson population as part of a longitudinal epidemiologic study of obstructive lung diseases. Migration to the area specifically for health reasons explained part of the high prevalences of disease found in the study. But natives still had higher rates of disease than those found generally in the United States, especially for asthma and allergic rhinitis; It was found that previous urban residence was related to the prevalence of several conditions, even when controlling for age, sex, and smoking habits. However, the trends were not always clear and the differences were not great enough to explain the Tucson population's much higher rates of these conditions than reported nationally or in similar studies elsewhere.

Previous lung disease and risk of lung cancer among men and women nonsmokers.

From 1982 to 1984, the authors conducted a population-based case-control study of lung cancer in men and women nonsmokers in New York State. In-person interviews were completed for 437 lung cancer cases (197 never smokers, 240 former smokers) and 437 matched population controls. Cases and controls were asked to report any history of physician-diagnosed nonmalignant lung disease; cases were more likely than controls to report such a history. Statistically significant associations were found for emphysema (odds ratio (OR) = 1.94, 95% confidence interval (CI) 1.10-3.43), chronic bronchitis (OR = 1.73, 95% CI 1.10-2.72), and the combined endpoint of emphysema, chronic bronchitis, or asthma (OR = 1.82, 95% CI 1.26-2.63). After adjustment for active and passive tobacco smoke exposure, emphysema, chronic bronchitis, and asthma (each condition and the combined endpoint) were significantly associated with lung cancer risk. The risk was more marked for squamous cell carcinomas and for subjects who were diagnosed at older ages, and it remained significant when surrogate interviews were excluded. These results are consistent with the hypothesis that certain prior lung conditions increase the risk of lung cancer in men and women nonsmokers.

The microheterogeneity of alpha 1-acid glycoprotein in inflammatory lung disease, cancer of the lung and normal health.

The concentration of alpha 1-acid glycoprotein (AGP, orosomucoid) was measured in sera from 19 patients with primary squamous cell carcinoma of the lung, 16 patients with an inflammatory lung disease and 17 persons with normal health. All sera were further subjected to crossed immuno-affinoelectrophoresis with addition of Con A in the first dimension and sugar in the second dimension. The distribution of AGP into four microheterogeneity forms, which were the result of this analysis, was estimated by measuring the area under the precipitation curve. The microheterogeneity patterns of AGP in the three groups were significantly different from each other (p less than 0.001). The total concentration of AGP in the two groups of patients was significantly different from the concentration in the healthy group (p less than 0.001).

Impact of interstitial lung disease on surgical morbidity and mortality for lung cancer: analyses of short-term and long-term outcomes.

BACKGROUND: This study investigated postoperative morbidity, mortality, and the long-term survival for patients with lung cancer who have interstitial lung diseases. METHODS: A retrospective chart review of 931 patients with lung cancer who underwent pulmonary resection at Chiba University Hospital between 1990 and 2000 was undertaken. Interstitial lung disease was defined by medical history, physical examination, and abnormalities compatible with bilateral lung fibrosis on chest computed tomography or high-resolution computed tomography (36 patients: 3.9%, interstitial lung diseases group). The remaining 895 patients (96.1%) were categorized as non-interstitial lung disease group. RESULTS: The incidence of postoperative pneumonia and acute or exacerbation of interstitial pneumonia was higher in the interstitial lung disease group (all P <.05). Thirty-day mortality was statistically equivalent between the interstitial lung disease and the non-interstitial lung disease groups (P =.30). The 5-year overall survivals were 62.5% (non-interstitial lung disease) and 35.6% (interstitial lung disease). Respiratory failure was the second main cause of death after the recurrence of primary cancer in the interstitial lung disease group. The risk factors for long-term mortality were interstitial lung diseases, advanced pathologic stage, male sex, high age, and positive smoking history (all P <.05). CONCLUSIONS: Interstitial lung disease was a risk factor for developing postoperative morbidity and mortality and poor long-term survival due to the occurrence of respiratory failure.

[Dust lung or dust-induced lung disease ( discussion on chronic dust-induced lung disease)].

The comment on the article by D. M. Zislin (Occupational Hygiene and Industrial Diseases, 1988, N 10) is presented. Proceeding from the author's own experience and literary data, the main statement of D. M. Zislin disputing the concept of dust pulmonary disease (DPD) in the modern occupational pulmonology, is analyzed. The common cause of pneumoconiosis and dust bronchitis has been identified as fibrogenic dust, allergic, carcinogenic and toxic characteristics of which can be only condition affecting the disease clinical character. The article shows that neither generality, nor the differences in the functional changes of external respiration can serve as a convincing argument for or against the existence of the concept of DPD. Modern histomorphologic studies give evidence that low-fibrogenic dusts practically simultaneously cause the onset of the pathologic process both in the interstitial tissue and in the bronchi, the outcome of the process being diffuse pneumosclerosis. The concept of DPD caused by low-fibrogenic dusts has been substantiated on the basis of common etiology and similar pathogenetic, clinical and functional manifestations.

[Clinical study on development of nontuberculous mycobacterial lung disease].

DEVELOPEMENT OF MAC LUNG DISEASE: An increase of nodular bronchiectatic type of MAC lung disease becomes a problem among respiratory physician today. The reason is still unknown, but it seems to be globally recognized that this type of MAC disease is developing particularly in middle-aged woman. Some papers mentioned the existence of such type of MAC lung disease already early in the 70s, in Japan. Yamamoto described that 17 cases of middle lobe type lung disease out of 154 non-photochoromogen cases, and 76.5% were female, in 1970. Shimoide also pointed such type of 39 cases out of 240 MAC lung disease and 84.6% were female, in 1980. Prince reported MAC lung disease seen in old and middle age female of 21 cases including lethality example of 4 cases without a precedent disease in 1989. After his report, the international consensus of this peculiar type of MAC lung disease seems to be spread. In 1989, we compared 72 cases of nodular bronchiectatic type of MAC lung disease and 56 cases of diffuse panbronchiolitis (DPB) that was a most typical chronic airway disease at that time in Japan. The average age of disease onset of DPB group was 37.0 +/- 16.3 years old and that of MAC group was 54.5 +/- 16.3 years old. The percentage of female was 32% in DPB group and 87.5% in MAC group. It was highly possible that two groups belong different parent population. We could grasp that nodular bronchiectatic type of MAC lung disease patients is a unique group. We observed the serial films of 21 cases of nodular bronchiectatic MAC lung disease, and divide the progression of the disease to sequential 7 steps as Fig. 1. Small nodules progress to cavities in mean about 10 years. However, why is MAC which is opportunistic pathogen with weak virulence, able to form a lesion at unimpaired lung parenchyma? Is there really normal site? Why dose it start from lingula? Why is MAC seen a lot in woman? While it is extremely pathognomonic clinical picture, and, is an extremely interesting problem, most are still unidentified. STUDY OF MAC LUNG DISEASE TREATMENT: It was known that Mycobacterium kansasii lung disease is healed with a chemotherapy like analog of anti-tuberculosis chemotherapy, already in those days. However, the results of MAC lung disease chemotherapy were extremely poor. We tried to express a physicians experience quantitatively as follows, in 1987. The results of 8 weeks sputum culture on Ogawa egg medium were converted semi-quantitatively to CFU numbers based on "Japanese standard guideline of Mycobacterium tuberculosis inspection". We exhibit the ratio of post-treatment consecutive 6 months culture yield to pre-treatment culture yield as response rate, about 110 pulmonary MAC cases. Through this study, we clarify the followings. The results of chemotherapy do not correlate susceptibility test for Mycobacterium tuberculosis. Multidrug regimen is more useful. Small extent of lesion is more responsive. Combination with aminoglycoside chemotherapy is more effective. These conclusions were almost same as the ATS guideline of 1990. New drugs such as, new macrolides and new quinolones appeared for pulmonary MAC treatment through the feedback from systemic MAC complicated AIDS treatments from the latter half of 90's. We measured the sensitive strain ratio at 2 mcg/ml of OFLX, CPFX, LVFX about 990 clinical isolates and could expect availability for M. kansasii or M. fortuitum, but these new quinolones are not enough effective for MAC. Also we examined MIC for various antimycobacterial agent by 50 MAC clinical isolates, and we could expect a certain availability of SPFX, GFLX, CPFX, CAM for MAC. The availability of clarithromycin (CAM) has been established through many randomized clinical trials for disseminated MAC complicated AIDS, but for pulmonary MAC, complete cure is still difficult if we use CAM including regimen. We performed surgical treatment for relatively young patients with localized lesions. We carry out the adaptation reference such as Table, now. The localization of the lesions become a problem at surgical resection. Through the study of our 55 surgical treatment cases, 8 cases (67%) relapsed out of 12 cases which had destructive airway structure in unresected lung field. On the other, only 1 case relapsed (10%) relapsed out of 10 cases without airway destruction in unresected lung. Therefore, even if there is a little dispersal focus without airway destruction in the other pulmonary lobe except purpose focus of resection, it seems that control is possible by post operational chemotherapy. LONG SURVIVAL: As overall consequence, we calculate the survival curves of 201 pulmonary MAC patients visited Tokyo National Hospital from 1953. The survival medium value was 7332 days. The prognosis of nodular bronchiectatic type was better than that of post-tuberculosis type. Extent of disease measured by chest X-ray examination at the time of first visit may be a most affecting factor to the survival rate.

Respiratory symptoms and obstructive lung diseases in iron ore miners: report from the obstructive lung disease in northern Sweden studies.

This is a population-based study on the prevalence of respiratory symptoms assessed by a mail questionnaire. The objective was to examine if work in an iron mine increased the risk of airway symptoms or obstructive diseases. The exposed group consisted of 114 previous or current male miners. Referents, 2472 males from the province, had never been employed by the mining company or worked as miners. Age, smoking and a family history of asthma were considered as possible confounders. The miners had an increased risk for respiratory symptoms (OR=2.2, 95% CI=1.4-3.1) including recurrent wheeze (OR= 2.4, 95% CI= 1.5-3.9), longstanding cough (OR= 1.8, 95% CI = 1.0-3.2), and for physician-diagnosed chronic bronchitis (OR=2.2, 95% CI= 1.0-4.5). Attacks of shortness of breath and asthma manifestations were similar between miners and referents. Higher risks in miners were found particularly among the non-smokers for physician-diagnosed chronic bronchitis (OR=9.2, 95% CI= 3.0-28) and for symptoms as well. A family history of asthma was less common among miners (9.2% vs. 17%, p < 0.05). We conclude that miners in a modern underground iron mine had an increased risk of respiratory symptoms. In contrast to other studies, this increased risk was particularly found in nonsmokers. A family history of asthma may be an important confounder in occupational studies of respiratory diseases.

Aortic aneurysm in a 74-year-old man with coronary disease and obstructive lung disease: is double jeopardy enough?

A previous decision analysis examined a patient with severe CAD, diminished ventricular function, and an abdominal aortic aneurysm and also concluded that CABG followed by aneurysm repair was optimal. This patient, who had well-preserved cardiac function but severely compromised pulmonary status, stood to gain less from CABG than would a patient with more severe coronary disease, thus accounting for the "close-call" between the CABG-AAA and AAA only strategies. Nevertheless, the analysis did emphasize the benefit of aneurysm repair, whether done alone or after CABG. The analysis also highlighted the significant risk of aneurysm rupture the patient is exposed to while recovering from CABG surgery. The operative mortality risks of the two procedures are similar; thus, the patient's total operative risk is approximately doubled if he undergoes both procedures rather than aneurysm repair alone. The key question raised by the analysis is whether this double jeopardy is more than compensated by the degree to which prior CABG reduces both short-term cardiac risk at subsequent aneurysm repair and long-term cardiac mortality. For this patient, who had good cardiac function, the gains appeared sufficient to offset the interval risk of aneurysm rupture and the additional risk associated with a surgical procedures. THE REAL WORLD The patient indeed underwent and tolerated CABG, although he had a stormy prolonged postoperative course due to pulmonary failure. After discharge from the hospital, he declined readmission for repair of the aneurysm. We did not model that possibility, clearly an inadequacy in our tree. Some six months later, the patient was still alive and was, reluctantly, readmitted for aneurysmorrhaphy. At that time, however, his pulmonary function had deteriorated and both the anesthesiologist and the pulmonary consultant stated unequivocally that further surgery was now impossible. In retrospect, the expected utility of CABG without aneurysm repair (thus providing only a decrease in the long-term mortality risk from his CAD) would have been 1.95 (DEALE) or 2.06 (Markov) years. Sensitivity analysis revealed that, even if long-term cardiac risk were completely eliminated by CABG, immediate aneurysm repair would have been a better approach had the patient's physicians known he would be likely to refuse or not be a candidate for the second operation. In summary, although the patient's comorbidities did indeed place him at significant operative risk for either aneurysmorrhaphy alone or two sequential procedures, the benefits to be gained were shown to far outweigh the risks when compared with expectant observation.(ABSTRACT TRUNCATED AT 400 WORDS)

Lung-reactive antibodies in sera of patients with farmer's lung disease.

Lung-reactive antibodies were detected in sera of patients with farmer's lung disease and in sera of healthy persons. A solid-phase radioimmunoassay was adapted for measurement of titers of human antibodies to sodium-dodecyl-sulfate-solubilized lung proteins. The titers of antilung antibodies in patients sera were 2-5 times as much as those of healthy persons. Using the immunoblotting technique, antibodies to individual lung polypeptides could be detected. Although the specificity patterns of antibodies to lung polypeptides differed from one serum to another, patients sera contained, in general, antibodies to larger numbers of lung polypeptides as compared to sera of healthy persons. The relationship between antilung antibodies and hypersensitivity pneumonitis is discussed.

Diagnostic problems in hypersensitivity lung disease.

Hypersensitivity Lung Disease (HLD) includes Hypersensitivity Pneumonitis (HP), IgE triggered asthma and Allergic Bronchopulmonary Aspergillosis (ABPA). HP and ABPA are neither common nor rare. Both are important to diagnose as they can result in progressive irreversible lung damage. Serologic tests are useful in diagnosing or excluding HP and ABPA although the diagnostic skill of the physician is of prime importance. We report eight cases which were diagnostic problems in which the initial serologic examinations were incorrect. The diagnostician must be aware of both the clinical possibility of the HLD but also of the possibility or probability that the serologic report is not correct.

[Expression and effect of connective tissue growth factor in premature rats with hyperoxia-induced chronic lung diseases].

OBJECTIVE: Lung fibrosis is the ultimate outcome of hyperoxia-induced chronic lung diseases (CLD) and connective tissue growth factor (CTGF) is correlated with fibrosis. This study investigated the role of CTGF in hyperoxia-induced CLD. METHODS: Fifty premature rats were randomly exposed to hyperoxia (Model group) and to room air (Control group) (n = 25 each). CLD was induced by hyperoxia exposure. The expression of CTGF was detected by immunohistochemical method at 1, 3, 7, 14 and 21 days after exposure. The severity of pulmonary fibrosis was evaluated. RESULTS: In the Control group there was a slight expression of CTGF in the bronchial epithelial cells and vascular endothelial cells. The intensity and range of CTGF expression in the Model group were similar to the Control group on days 1, 3 and 7 of exposure. On the 14th day, CTGF was expressed in some alveolar epithelial cells, fibroblasts and interstitial cells, and the intensity of CTGF expression increased significantly compared with the Control group, with the IODT of CTGF of 10.53 +/- 4.24 vs 5.58 +/- 1.18 (P < 0.01). On day 21, the expression intensity and range of CTGF in the Model group (IODT: 16.61 +/- 5.39) increased compared with that of Control group (P < 0.01). The expression of CTGF was correlated with the degree of fibrosis in the Model group on days 14 and 21 (r = 0.903, r = 0.926 respectively, P < 0.01). CONCLUSIONS: The CTGF expression increased with the time of hyperoxia exposure and the development of fibrosis. CTGF is closely related to the development of hyperoxia-induced pulmonary fibrosis.
