The authors analysed 116 hospitalized patients who, in their routine cytologic examination of the sputum, had also a cytomorphologic finding of lymphocytes. The greatest majority of these patients, 63 of them or 54.3% suffered from malignant neoplasm. Out of these 63 patients, 53 of them or 45.7% suffered from primary bronchial carcinoma, whereas 10 patients or 8.6% had non-Hodgkin's lymphoma, metastatic lung cancer of extrathoracic primary localization, Hodgkin's lymphoma, while two patients were supposed to have lung neoplasm. Our study also revealed that 14 patients (out of 116 hospitalized patients) or 12.0% suffered from broncho-pleuropneumonia, 13 or 11.2% from an active pulmonary tuberculosis, 7 or 6.0% from a chronic obstructive bronchitis, 5.1% from sarcoidosis, 3.4% from post tuberculosis pulmonary changes while 2.5% of the patients were found to have a pleural empyema. One case of bronchial asthma, tuberculous pleurisy, bronchiectasis, hamartoma, hemoptysis and a pulmonary infarction were found as well. Due to their own experience the authors conclude that the lymphocytes in the sputum were found to be the most frequent in patients suffering from primary bronchial carcinoma, broncho-pleuropneumonia and pulmonary tuberculosis but that they could also be found in many others pathologic changes of pulmonary parenchyma.

The evidence concerning a relationship between work in the aluminum industry and lung disease has been reviewed using epidemiologic criteria. Adequate data on environmental exposure are rarely presented. Case series on aluminum potroom workers over the past 50 years have identified an asthmalike syndrome that appears to be due to an irritant rather than an allergic mechanism. These studies have been supported by evidence of within shift variability of measures of lung function. However, to date, there is inadequate evidence to resolve the question of whether potroom exposure initiates asthma or merely precipitates asthmalike symptoms in a predisposed individual. Cross-sectional studies have demonstrated evidence of reduced lung function, consistent with chronic airflow limitation. In exposed aluminum smelter workers compared to unexposed control subjects. Cigarette smoking, the major potential confounding variable, has been measured and accounted for in multivariate analyses. To date, evidence is lacking from longitudinal studies about the development of disabling chronic obstructive lung disease. Exposure to coal tar pitch volatiles in the production and consumption of anodes has biologic plausibility for an association of lung cancer with work in an aluminum smelter. Although retrospective mortality studies have failed to account for the probable high prevalence of smoking in blue collar workers, the relative risk of lung cancer is very low if present at all. Pulmonary fibrosis has not been shown to be a significant problem in aluminum smelter workers. Future research in the aluminum industry needs to concentrate on longitudinal studies, preferably with an inception cohort for the investigation of potroom asthma.

A set of 620 patients was examined. Out of them, 245 suffered from lung carcinoma of different type and stage, 28 suffered from other malignant tumors, 37 were affected with benign tumors, and 166 were suffering from a nonmalignant respiratory disease (tuberculosis, nonspecific pneumonia, chronic bronchitis, abscesses, cysts, asthma, lung fibrosis, bronchiectasis and sarcoidosis). In addition to these patients, 144 blood donors were examined who represented the control group of healthy individuals. In a blind test another set of 266 persons was examined. By completing the values of selected markers (orosomucoid, prealbumin, glycoprotein electrophoresis, erythrocyte sedimentation, age of the individual, and the number of smoked cigarettes) into the discrimination rule and by calculating the discrimination function, a sensitivity of 80.6% and a specificity of 75.6% were obtained. A comparative cytological examination of the same set revealed lower sensitivity (61.0%) but higher specificity (98.0%). These values were verified in a blind test, as the patients were admitted to the hospital. Sensitivity in lung cancer was found to be 83.9%; in nonmalignant diseases the respective value was 77.1%. This approach can be applied to individuals suspect of cancer, in secondary prevention and in individuals with a high risk of lung cancer.

Sulbactam/cefoperazone (SBT/CPZ), a new antibacterial drug, was administered to 14 cases with respiratory infections for a duration of 5 approximately 13 days at a daily dose of 4 g. Diagnoses of these patients were 7 respiratory tract infections, and 7 bronchopneumonias. The underlying diseases were chronic pulmonary emphysema in 6 cases, bronchial asthma in 2 cases, and one each of bronchiectasis, diffuse panbronchiolitis and lung cancer with bronchoesophageal fistula. All patients had underlying respiratory diseases and/or were more than 70 years old. The rate of clinical efficacy was 78.6%. The incidence of penicillinase production by isolated bacteria was 18.2% and that of cephalosporinase was 63.6%. SBT/CPZ was expected to be more effective than CPZ alone in 3 cases judging from the susceptibility of the bacterial strains concerned, to antibiotics. No side effects were observed. We conclude that SBT/CPZ is useful in the treatment of respiratory infections of patients of advanced age and/or with underlying respiratory diseases.

A traditional Chinese remedy, Qing-Fei-Tang (Seihai-to, T90), has been used for treatment of chronic respiratory diseases with long-lasting cough and sputum, e.g. chronic bronchitis. We examined the effect of T90 and its main component flavonoid, baicalein, on the lucigenin-dependent chemiluminescence (CL) and leukotriene B4 (LTB4) synthesis of human alveolar macrophages (AM). AM were obtained by bronchoalveolar lavage from patients with various respiratory diseases, including sarcoidosis, idiopathic pulmonary fibrosis, bronchial asthma, chronic bronchitis and lung cancer. CL were observed by stimulating 1 x 10(5) AM with phorbol myristate acetate in the presence of lucigenin. LTB4 were generated by incubating 1 x 10(6)/ml AM with Ca ionophore A23187 for 30 min and determined by reverse phase high performance liquid chromatography and radioimmunoassay. T90 (0.2-2.0 mg/ml) and baicalein (0.1-100 microM) inhibited both CL and LTB4 production of AM in a dose-dependent fashion. These inhibitory effects were not due to cytotoxic effects of the procedure because neither 2 mg/ml T90 nor 100 M baicalein affected the viability of AM nor lactate dehydrogenase release from AM. These results suggest that T90 exerts its effect on inflammatory lung diseases through the anti-inflammatory action, i.e. inhibiting the oxidative and arachidonate metabolism of local inflammatory lung cells.

A defined general population of 159,200 male and female native Swedes born in the period of 1911-1940, from an urban catchment area of the then only general hospital, was followed over a decade (1970-1979) with regard to inpatient hospitalization for all kinds of diagnoses. Psoriasis cases (n = 372) are significantly (p less than 0.001) associated with a spectrum of diseases: male as well as female psoriatics seem to show excess rates of viral infections, alcoholism, hypertension, pneumonia, liver cirrhosis, urticaria, and rheumatoid arthritis. Psoriasis in males only seem to be associated with iritis and ankylosing spondylitis, whereas psoriasis in females only is associated with lung cancer, diabetes, obesity, myocardial infarction and asthma.

A sensitive monoclonal antibody based ELISA was used to detect cell-free interleukin-2 receptor (IL-2R) in the body fluids of patients with acquired immune deficiency syndrome (AIDS), a variety of other disease conditions and a control group of apparently healthy (heterosexual and homosexual) males. Two of the 25 control donors showed low titers (1:8) of IL-2 receptor in the serum samples; the cerebrospinal fluid (CSF) specimens from these individuals proved negative. However, serum and CSF specimens from all the 9 patients with AIDS showed significantly elevated titers (range 1:128 to 1:4096) of IL-2 receptor. The presence of moderate titers (range 1:128 to 1:512) of circulating IL-2 receptor could also be detected in all of the 4 patients with acute lymphocytic leukemia. IL-2 receptor was detectable in the CSF and/or serum specimens from 3 of 3 patients with lung cancer, 3 of 4 patients with acute hepatitis B infection, and 2 of 3 patients with multiple sclerosis. IL-2 receptor could not be detected in the serum or CSF specimens originating from patients with legionellosis (3/3), asthma (3/3), or those with non-pulmonary febrile bacterial infections (4/4). It is concluded that soluble IL-2 receptor may be found in serum or CSF specimens from patients with certain (but not all) disease conditions including AIDS. The conspicuously elevated titers of cell-free IL-2R in the body fluids of patients with AIDS may contribute to the drastic impairment of the immune system regulation observed in such patients.

In 1950-1960, a cohort of dust-exposed workers and a cohort of multiple matched unexposed subjects was set up from the files of preventive medical checkups performed in 1,089 Viennese plants. Male workers with a history of long-term exposure to nonfibrous particulates in different industries (metal, ceramics, brick, glass, stone etc.) aged greater than or equal to 40, and male workers without dust exposure (matched for residency, start of observation, age, and smoking) were followed up to 1980 or death (48,960 person yr). By life table methods, dust-exposed workers compared to unexposed workers showed a reduced survival of age 60 (p less than 0.0001), due to lung cancer (123 exposed, 87 controls, p = 0.001), stomach cancer (48/27, p = 0.003), silicosis (40/0), emphysema, bronchitis and asthma (41/23, p = 0.007). No difference in mortality from cardiovascular diseases was observed (p greater than 0.50). We concluded that heavy and long term exposure to respirable particulates is related to increased lung cancer mortality after age 60. A comparison of 2,212 deaths among Austrian silicotics, with deaths in the corresponding population showed a relation between lung cancer and silicosis (p less than 0.001), fairly independent of age and time-period. The estimated relative lung cancer risk of Austrian silicotics in the period 1955-79 averaged 1.41 (95% confidence 1.21-1.64).

Today it is believed that mast cells (MC) are important not only in IgE-mediated reactions, but also in delayed hypersensitivity reactions, and that their functions are mediated by factors released by T lymphocytes. Recent studies have shown their presence in bronchoalveolar lavage (BAL) of patients with asthma and interstitial lung disease. MC have been identified by us in the BAL of patients with sarcoidosis and lung cancer, and in controls. A statistically significant correlation has been found between MC and lymphocytes, CD3+ and CD4+ cells present in BAL, thus supporting the hypothesis of interactions between T lymphocytes and MC in immune reactions at the alveolar level.

Absorption of harmful and irritative components of cigarette smoke by nonsmokers may result in both acute and long-term health problems. Persons with asthma or coronary artery disease are at particularly high risk of developing problems. Children living with smokers are at increased risk of persistent middle ear effusions and lower respiratory tract infections. Nonsmokers married to smokers have an increased risk of lung cancer.
