To evaluate the clinical usefulness of Ga-67 imaging for the assessment of radiation pneumonitis, 12 patients who had developed radiation pneumonitis after receiving radiotherapy alone for non-small-cell lung cancer from 1979 through 1988 were reviewed. Diffuse bilateral Ga-67 uptake occurred in 5 out of the 12 cases; in the other 7 cases, Ga-67 uptake was confined to the irradiation lung. Conversely, chest radiography showed infiltrates only in the irradiated lung. Histopathology of the lung in four out of the five cases that showed diffuse Ga-67 uptake in the lung, however, revealed that the lung outside the radiation field with Ga-67 uptake was consistent with interstitial pneumonitis induced by radiation. These results suggest that radiation pneumonitis could extend beyond the irradiated lung and that Ga-67 imaging is more useful than chest radiography for the assessment of the spatial extent of radiography pneumonitis.

A 63-year-old man with Eaton-Lambert syndrome manifested by marked respiratory failure was reported. He began to notice blepharoptosis and diplopia in September, 1987, followed by weakness and easy fatigability in bulbar, neck and limb muscles in association with impotence by February, 1988. On admission in August, 1988, Gowers' sign, decreased tendon reflexes and muscle weakness improved by the injection of edrophonium were found. Anti-acetylcholine receptor antibody was negative. Single muscle action potential evoked in the thenar muscle was abnormally low in amplitude with the stimulation of the median nerve: repetitive nerve stimulation study revealed the waning at the low rates, but the waxing at the high rate (30 Hz), suggesting the diagnosis of Eaton-Lambert syndrome. Early gastric cancer (adenocarcinoma) was diagnosed from needle biopsy specimens in August, 1988, but no other neoplasm including thymoma or lung cancer was found. After subtotal gastric resection in September, 1988, he failed into respiratory failure, requiring artificial ventilation for seven months. Plasmapheresis and drugs such as anticholinesterase, guanidine hydrochloride, and corticosteroid were ineffective for the recovery from weakness in respiratory muscle. Lung cancer was suspected, based on a chest X-ray in March, 1989, and one month later he died of pneumonia. At autopsy, small cell carcinoma of the lung was observed, but there was neither recurrence nor metastasis of the gastric cancer. Emphasis was placed on the respiratory failure in Eaton-Lambert syndrome which has rarely been reported.

We have previously reported that increased tracer accumulation on delayed 123I-IMP scintigraphy is associated with atelectasis and inflammation. The purpose of this study was to evaluate the diagnostic values of delayed 123I-IMP lung scintigraphy, compared with gallium scintigraphy. Ten patients with atelectasis caused by lung cancer and 7 patients with inflammatory diseases were studied. Inflammatory lung disease included 4 cases of pneumonia, 2 of interstitial pneumonitis, and 1 of diffuse panbronchiolitis. Delayed 123I-IMP scintigraphy was performed 24 hours after intravenous injection of 111 MBq of 123I-IMP. In 14 patients, the SPECT images were obtained. Gallium scintigraphy was done within 7 days of 123I-IMP scintigraphy and the images were obtained 72 hours after the administration of 111 MBq of 67Ga-citrate. 123I-IMP scintigraphy was compared with gallium scintigraphy for its ability to detect atelectasis. The degree of uptake by the collapsed lobes was judged visually on planar images and rated using four grades: negative, slight, moderate and heavy. All the cases showed moderate or intense uptake on the 123I-IMP images, whereas with gallium scintigraphy there was no change corresponding with lobar collapse in 8 out of 10 cases. Of the remaining 2 cases, one had tumor in the collapsed lobe and the other had obstructive pneumonia. In inflammatory lung diseases, the correlation of 123I-IMP and gallium images regarding degree of change shown on chest X-ray film was studied. The degree of correlation was classified using four grade: poor, fair, good and excellent.(ABSTRACT TRUNCATED AT 250 WORDS)

The type of lung disease caused by metal compounds depends on the nature of the offending agent, its physicochemical form, the dose, exposure conditions and host factors. The fumes or gaseous forms of several metals, e.g. cadmium (Cd), manganese (Mn), mercury (Hg), nickel carbonyl (Nl(CO)4, zinc chloride (ZnCl2), vanadium pentoxide (V2O5), may lead to acute chemical pneumonitis and pulmonary oedema or to acute tracheobronchitis. Metal fume fever, which may follow the inhalation of metal fumes e.g. zinc (Zn), copper (Cu) and many others, is a poorly understood influenza-like reaction, accompanied by an acute self-limiting neutrophil alveolitis. Chronic obstructive lung disease may result from occupational exposure to mineral dusts, including probably some metallic dusts, or from jobs involving the working of metal compounds, such as welding. Exposure to cadmium may lead to emphysema. Bronchial asthma may be caused by complex platinum salts, nickel, chromium or cobalt, presumably on the basis of allergic sensitization. The cause of asthma in aluminium workers is unknown. It is remarkable that asthma induced by nickel (Ni) or chromium (Cr) is apparently infrequent, considering their potency and frequent involvement as dermal sensitizers. Metallic dusts deposited in the lung may give rise to pulmonary fibrosis and functional impairment, depending on the fibrogenic potential of the agent and on poorly understood host factors. Inhalation of iron compounds causes siderosis, a pneumoconiosis with little or no fibrosis. Hard metal lung disease is a fibrosis characterized by desquamative and giant cell interstitial pneumonitis and is probably caused by cobalt, since a similar disease has been observed in workers exposed to cobalt in the absence of tungsten carbide. Chronic beryllium disease is a fibrosis with sarcoid-like epitheloid granulomas and is presumably due to a cell-mediated immune response to beryllium. Such a mechanism may be responsible for the pulmonary fibrosis occasionally found in subjects exposed to other metals e.g. aluminium (Al), titanium (Ti), rare earths. The proportion of lung cancer attributable to occupation is around 15%, with exposure to metals being frequently incriminated. Underground mining of e.g. uranium or iron is associated with a high incidence of lung cancer, as a result of exposure to radon. At least some forms of arsenic, chromium and nickel are well established lung carcinogens in humans. There is also evidence for increased lung cancer mortality in cadmium workers and in iron or steel workers.

Clinical evaluation, safety and kinetics in serum of sulbactam/cefoperazone (SBT/CPZ) in patients with lower respiratory tract infections have been studied in a multicenter trial participated by 28 institutions in Kyushu area during a period of 13 months from March 1987 to March 1988. 1. Mean peak serum levels of SBT and CPZ in 35 patients up to 4 hours after intravenous infusion of 2 g of SBT/CPZ were 38.2 +/- 17.3 micrograms/ml for SBT and 104.3 +/- 31.4 micrograms/ml for CPZ. Serum half-lives of SBT and CPZ were 0.76 hour and 1.53 hours, respectively. These results were in similar ranges to those reported elsewhere for SBT/CPZ. 2. Serum half-lives of SBT and CPZ after intravenous infusion of 2 g of SBT/CPZ were not significantly prolonged in patients with moderate liver or kidney dysfunctions. 3. Clinical efficacy rates of SBT/CPZ in 217 patients were 93.1% (81/87) for pneumonia, 93.3% (14/15) for lung abscess, 78.9% (15/19) for acute exacerbation of chronic bronchitis, 57.1% (4/7) for diffuse panbronchiolitis, 72.4% (21/29), 74.4% (32/43) and 100% (9/9) for infections concurrent to bronchiectasis, chronic respiratory disease and pulmonary emphysema, respectively. Those were 50% (1/2) for bronchitis associated with lung cancer and 66.7% (4/6) for empyema. The overall efficacy rate was 83.4% (181/217). 4. Clinical efficacy rate of SBT/CPZ for pneumonia in patients with underlying diseases such as lung cancer, pulmonary tuberculosis and pneumoconiosis, etc, was 85.3% (29/34) and was not significantly different from the efficacy rate of 98.1% (52/53) in patients without these underlying diseases. 5. Of 30 patients who failed to respond of previous antibiotic treatments, 21 were effectively treated by SBT/CPZ. 6. Bacteriological eradication rates against Pseudomonas aeruginosa, Haemophilus influenzae and Streptococcus pneumoniae were 42.9% (9/21), 87.5% (14/16) and 100% (5/5), respectively. The overall eradication rate in all cases including polymicrobial infections was 72.8% (67/92). 7. The high levels of peak serum concentration of CPZ, and the difference between serum levels of SBT and of CPZ seemed to contribute to the high clinical efficacy. 8. Adverse reactions occurred in 2.8% (6/217) of the patients, and consisted primarily of rash and diarrhea. Laboratory abnormalities were observed in 8 patients during the study. These were elevations of S-GOT and S-GPT, and eosinophilia. 9. SBT/CPZ is a very useful drug in the treatment of lower respiratory tract infections as it has become available just in time when increase in resistant organisms to beta-lactams is notable.

To determine the clinical utility of airway carcinoembryonic antigen (CEA) concentrations to distinguish malignant from inflammatory airway disease in patients undergoing bronchoscopy, we determined CEA concentrations by enzyme immunoassay in bronchial washings recovered in 48 subjects, including 20 patients with central lung cancer, 18 patients with chronic bronchitis, and ten nonsmoking patients with a diagnosis of pneumonia or peripheral granuloma. Concentrations of CEA in bronchial washings were standardized by using the total protein concentration in recovered fluid (CEA/TP). Concentrations of CEA were significantly increased in bronchial washings recovered from both patients with chronic bronchitis and lung cancer compared with patients with pneumonia or granuloma (252 +/- 47 ng/mg and 199 +/- 64 ng/ml vs 62 +/- 11 ng/mg, SEM, p less than 0.005). Airway CEA concentrations in patients with chronic bronchitis were somewhat increased compared with concentrations recovered from a cancer-involved airway (252 +/- 47 ng/ml vs 199 +/- 64 ng/mg, SEM, p less than 0.05). Measurement of airway CEA concentrations is not useful in distinguishing malignant from inflammatory airway disease as airway concentrations of CEA may be markedly increased in patients with both conditions.

A phase I-II study of intraoperative radiotherapy (IORT) for Stage III lung cancer was performed in 34 patients during a period of 58 months. Loco-regional treatment included tumor resection if technically feasible, IORT boost of electron beams using moderate single doses (10-15 Gy) to tumor bearing areas and external photon beam irradiation (46-50 Gy in 5 weeks) using conventional fields. Indications for this study were unresectable hiliar tumors (14, 41%), and mediastinal, hiliar and/or chest wall residual disease following resection (20, 59%). Thirty-four procedures, with 40 IORT fields, have been analyzed to describe the relevant technical aspects and the toxicity. IORT was delivered using acrylic transparent cones of different diameters. Surgical approach consisted in a lateral thoracotomy in all patients (21 right side and 13 left side). Tissues included within the IORT field were: tumor or residual tumor tissues (34, 100%), collapsed lung parenchyma and main bronchus not surgically manipulated (14, 41%), bronchial stump and vascular suture following resection (19, 55%), mediastinal structures (20, 58%), and brachial plexus (1, 3%). The bronchial suture was covered with pleural or pericardial flap after IORT in 10 cases (29%). Life threatening toxicity related to IORT consisted in broncho-pleural fistula (1, 3%) and massive hemoptysis (1, 3%). Other reversible toxic events were acute pneumonitis (12, 85%) and esophagitis (10, 50%). Long term asymptomatic lung fibrosis was detected in 11 cases (32%). Median survival time for the entire group has been 12 months. With a median follow-up time of 12 months the freedom from thoracic recurrence rate is 30% (65% in cases with tumor resection). Projected actuarial survival rates at 4 years were 28% for resected group and 7% for unresected cases. This experience supports IORT as a feasible alternative modality to be used in the management of locally advanced lung cancer. Tolerance of thoracic organs to moderate doses of IORT appeared to be adequate and local control is achieved in certain patients. These results deserve further investigation and confirmation trials.

We report an autopsy case of encephalitis principally confined to the bilateral thalamus and associated with pulmonary and gastric cancers. An 81-year-old man exhibiting behavioral abnormalities and progressive somnolence died of pneumonia 11 months after onset. Because the patient had lung cancer and no definite cause of the encephalitis was found, this case was categorized as one of paraneoplastic encephalomyelitis. This may be the first reported case of this condition in which the central nervous system (CNS) lesion was located predominantly in the thalamus.

A case of severe bacteremic pneumococcal pneumonia which developed in a patient with lung cancer, who was taking ofloxacin for chemoprophylaxis, is presented. Pneumonia resolved well with intravenous penicillin G. Infection by and colonization with Streptococcus pneumoniae might become a problem with increasing use of the fluoroquinolones.

This paper attempts to discuss the shape of inequalities in health in the Republic of Ireland by focusing on social class, gender and regional inequalities in health outcomes as shown in annual publications of vital statistics and in various research studies. The Republic of Ireland has a demographic profile of rapid population increase, unique in Europe. While the birth rate is the highest in Europe, the infant mortality rate is relatively low, yet the perinatal mortality rate is relatively high. Attempts are made to analyse social class variations in mortality and morbidity rates but, except for psychiatric care, Irish data on health by social class are scarce. There exist more data on gender inequalities which pinpoint the particular vulnerability of Irish women to ischaemic heart disease and certain types of cancer. Regional analysis of vital statistics reveals the vulnerability of people in urban areas (compared to rural areas) to cancer of the trachea, bronchus and lung, cirrhosis of the liver, tuberculosis of the respiratory system, pneumonia, and bronchitis, emphysema and asthma. In comparison to several European countries, Irish standardized mortality rates were the worst for urban women dying from lung cancer, and for urban men and women, Irish standardized mortality rates were the worst for non-rheumatic heart disease and respiratory tuberculosis. Various studies of morbidity of the elderly clearly reveal the hidden clinical iceberg of symptoms which are not presented to the health care system. Unfortunately, there is relatively little evidence of the health situation of disabled people, the travelling community or the long term unemployed.(ABSTRACT TRUNCATED AT 250 WORDS)
