From May 1986 until July 1987, oral morphine hydrochloride in water solution was used in terminal patients, under a strict protocol of administration, and complying with the basic principles of Palliative Care. A retrospective study was carried out on the 40 patients who had received the drug for more than three consecutive days. As shown in Table 1, the average age of the treated patients was 70 years. The ambulatory patients represented 27.5% of the sample. The average initial dose was 60 mg, and the average maintenance dose was 120 mg. The median treatment time was 45 days. "Good" results were achieved in 85% of the patients, and "fairly good" in the remainder ("good" results were defined as "satisfactory symptom control, good life quality"--in this group there were some patients who obtained total suppression of the symptoms and optimal life-quality, i.e. "excellent" results; "bad" results were defined as "total absence of therapeutic effect"; and "fairly good" results, the intermediate cases). The more frequently treated symptoms were: 67.5%, pain due to tumor mass; and 20%, pain due to nerve compression-invasion, bone pain, and dyspnoea due to pulmonary metastases or primary lung cancer: total symptoms was more than a hundred per cent, because a number of patients had more than one symptom. Whenever necessary, adjuvant drugs were employed. Side effects were seen in 37% of the patients (specially nausea, vomiting, constipation, and somnolence for more than four days).(ABSTRACT TRUNCATED AT 250 WORDS)

Although etiological diagnosis represent a major issue in occupational health, it is frequently difficult to achieve because of the concurrent effect of a multitude of both work-related and non-work-related pathogenic factors. A construction worker, exposed for over 20 years to silica and silicate dust, asbestos dust and vibrations transmitted through the hand-arm axis, complained of dyspnoea a cough and peripheral paraesthesia. Two years later he developed scleroderma-like skin lesions in the appendages, and a small-cell bronchogenic carcinoma was subsequently revealed by radiological and bronchoscopic examination. The analysis of a single case failed to provide any substantial support for the hypothesis that scleroderma and lung cancer have an occupational origin; however, we believe it is significant that occupational exposure to chemical and physical agents inhibiting the immune response is often observed in association with some kinds of immune abnormalities, such as those of scleroderma and oat-cell cancer.

An autopsy case of an 18-year-old boy with adenocarcinoma of the lung is reported. He experienced dyspnea and hemosputum in July 1988. Chest radiographs showed a diffuse bilateral streaky shadow, bilateral pleural effusion and cardiac enlargement. The diagnosis of adenocarcinoma was made by transbronchial biopsy at another hospital. He visited the National Cancer Center Hospital on October 7, 1988. The diagnosis of lung cancer was strongly suggested by positive immunohistochemical staining for pulmonary surfactant apoprotein in biopsy specimens from supraclavicular lymph nodes. Intensive systemic survey demonstrated no other primary site than the lung. The patient was treated with cisplatin, adriamycin and etoposide and his subjective symptoms such as cough and dyspnea significantly improved over the next three months. Tumor shadows in the lung increased steadily, however after February, 1989. A significant lymphangitic spread of the carcinoma and marked obsteoblastic bone metastases were revealed at autopsy.

To determine the efficacy and safety of pefloxacin in the treatment of lower respiratory tract infections, a multicentre trial involving four departments of respiratory diseases was performed. One hundred and eight patients were admitted to the study: most of them were affected with exacerbations of chronic bronchitis or with pneumonia complicating lung cancer. Isolation and identification of responsible microorganisms from bronchial secretions was possible in 78 patients. Seven patients were withdrawn, one for worsening of the underlying disease and six for early side-effects. Thus, of 108 patients recruited, 101 completed the course of therapy (pefloxacin 400 mg bd for 5-14 days) and could be submitted to final evaluation. Of these 43 (42.6%) were cured and 48 (47.5%) showed improvement. Eradication of responsible microorganisms was achieved in 70 (90.9%) of 77 patients microbiologically evaluated. Side-effects of moderate severity were observed in 12 patients (gastrointestinal disturbances in 11 and dyspnoea in one); these did not necessitate discontinuation of therapy.

Endobronchial tuberculosis is not as well-known to internists as tuberculosis involving the lung parenchyma. Five cases with this condition are reported to illustrate the varied clinical manifestations. The presenting features of the 5 cases were lobar or lung collapse, unresolved pneumonia, dyspnoea and stridor. Bronchostenosis developed in 2 patients many years following chemotherapy, while stenosis of the trachea developed in one patient during chemotherapy. In another patient, the tuberculous granulation tissue simulated a lung cancer at bronchoscopy. Diagnosis can be difficult as endobronchial tuberculosis can occur in the absence of chest X-ray abnormality and sputum smear may also be negative for acid fast bacilli (AFB). Therefore, bronchoscopy should be done when the condition is suspected in a patient who has unexplained cough, wheezing, dyspnoea or haemoptysis. The modalities of treatment for fibrostenosis of a large airway include surgical resection followed by anastomosis, balloon dilatation, laser photoresection or a combination of both procedures.

Seven cases (1.9%) of simultaneous bilateral pneumothoraces were found in a retrospective study of 377 patients with spontaneous pneumothorax during the period from July, 1977 to June, 1989. Their symptoms were essentially those of unilateral pneumothorax, but with more severe dyspnea. All but two cases, both young, had underlying pulmonary diseases. Three (two lung cancers and one metastatic lung disease) had malignant pulmonary disease. During this period, five lung cancer patients were complicated with pneumothorax, and two of them had simultaneous bilateral pneumothoraces. Therefore the frequency of bilateral pneumothoraces in the lung cancer patients associated with pneumothorax is high. In these three patients with malignant disease, tube drainage was carried out but all died of respiratory failure. Two senile patients had small bilateral pneumothoraces. Bed rest without invasive treatment led to successful cure. Two younger patients without underlying pathology initially underwent tube drainage, followed by operation. We conclude that many patients with simultaneous bilateral spontaneous pneumothoraces have underlying pulmonary disease, the frequency of lung cancer being particularly high. Young patients without underlying disease should be operated on following alleviation of symptoms by tube drainage. Older patients and patients with malignancy should be treated with great care and individually.

45 patients with lung cancer at the III and IV stage were treated with once-a-week radiation therapy. Treatments were carried out with a daily fraction, at beginning, of 880 rad (2100 ret) (14 pz.) and 550 rad (1500 ret) afterwards. In both cases the total dose was 4400 rad. All the patients had symptoms of locally advanced cancer: cough (46%), hemoptysis (31%), dyspnea (62%) and chest pain (28%). All of them were out-patients (ECOG 0-1) and presented a Performance Status by Karnofsky of 50-80. The average age was 60 (median 65, range 38-85) with a raised percent (50%) of collateral illness. The selection of once-a-week technique was determined by the bad prognosis and the necessity of symptoms' control, allowing the patients to stay in his proper social and family group. All the time of therapy and the follow-up the values of Performance Status were assigned scrupulously. The analysis showed that the 80% of the patients had a subjective improvement which lasted, on average, 4 months (range 1-21) with an increase of 20 points of Performance Status after the end of therapies. Concluding, the high percentage of success on symptoms presented by the patients, confirms the validity of weekly radiotherapy, which guarantees, besides the palliative effect, the psychological integrity which is necessary in the last period of the life of cancer patient.

The prognostic staging of cancer in general, and lung cancer in particular, has customarily depended mainly on morphologic distinctions. The gross anatomic extensiveness of cancers is cited with TNM stages that describe the primary tumor (T), spread to regional lymph nodes (N), and metastatic dissemination (M) to distant sites. Microscopic characteristics are cited according to the cancer's cell type (e.g., adenocarcinoma, epidermoid carcinoma) and/or grade of differentiation (e.g., well differentiated, poorly differentiated, anaplastic). Although the clinical manifestations, functional effects, and associated co-morbidity of a cancer are universally recognized as having major prognostic importance, they have not been classified with a standard system of taxonomy. When considered at all, clinical phenomena have been cited with a surrogate index of "performance status" that ignores the underlying clinical dysfunctions while being greatly affected by non-clinical phenomena, such as the patient's psychic status, economic motivations, and system of social support. The current research was done to develop a standard system of taxonomy (or "staging") for the prognostic impact of clinical distinctions in patients with primary lung cancer. Appropriate data were obtained, computer-coded, and analyzed from medical records for the complete clinical course of an inception cohort of 1266 patients who were first treated at either the Yale-New Haven Hospital or the West Haven Veterans Administration Hospital during the interval January 1, 1953-December 31, 1964. The information under analysis included clinical phenomena as well as anatomic extensiveness (TNM stage), microscopic histology, the chronometric duration of the interval from the first symptom of lung cancer to zero time, the iatrotropic reason why the patient sought medical attention, the presence of anemia, the amount of customary cigarette use, and the conventional demographic data for age and gender. The main clinical phenomena were expressed in variables for symptom pattern severity, and co-morbidity. Symptom pattern referred to the existence of specific pulmonic symptoms (e.g., hemoptysis), systemic symptoms (e.g., complaint of weight loss), and metastatic symptoms that might be mediastinal (e.g., superior vena cava syndrome), regional (e.g., the Horner syndrome), or distantly metastatic (e.g., central nervous system). The symptom severity variable included the amount of weight loss, and the existence of severe dyspnea or particularly severe tumor effects (such as mental obtundation, rather than hemiparesis in patients with CNS metastasis). Prognostic co-morbidity was cited for coexisting diseases, such as recurrent myocardial infarctions, that might be more lethal than the lung cancer itself.(ABSTRACT TRUNCATED AT 400 WORDS)

A 46-year-old man was admitted to our hospital on Mar. 16, 1988 with the chief complaint of productive cough. The chest roentgenogram and tomogram showed a tumorous shadow in the right upper lobe, accompanied with stenosis of the trachea and the right main bronchus. Bronchofiberscopic examination confirmed a nodular tumor protruding into the lower part of the trachea from the right lateral wall and nearly complete obstruction of the right main bronchus. Pathological specimen obtained by transbronchial biopsy revealed "low differentiated adenocarcinoma". It was highly suspected that the primary lung cancer had directly invaded the trachea and the right main bronchus. His symptoms and roentgenological findings remarkably improved after radiation therapy. He was discharged on May 12. On Sep. 14, he was admitted to our hospital again because of hoarseness, general fatigue and increasing dyspnea. The chest CT demonstrated severe stenosis of the trachea, which was treated with another radiation therapy. Although his symptoms diminished, he had a sudden onset of high fever on Oct. 15. Immediately a blood culture and transtracheal aspiration (TTA) were performed. Gram-negative bacilli were isolated from the blood culture four days later. The administration of fosfomycin and tobramycin was started. However he died because of massive hemoptysis on Oct. 23. Several days after the death, an isolated strain was identified as Capnocytophaga ochracea by the biochemical characteristics. Culture of sputum obtained by TTA was negative for Capnocytophaga ochracea. Septicemia due to Capnocytophaga spp. is very rare and only one case (due to Capnocytophaga sputigena) has been reported until now in Japan. Our patient is thought to be the first case of septicemia due to Capnocytophaga ochracea in Japan.

The effects of lung resection on exercise capacity and perception of symptoms were studied in 47 patients aged 39-73 (mean 58.3) years. Twenty had a pneumonectomy and 27 a lobectomy, all for lung cancer. Forced expiratory volume, maximal inspiratory and expiratory pressures, and progressive maximal one minute incremental cycle ergometer exercise performance were measured before and after surgery. Breathlessness and leg discomfort were assessed with a modified Borg scale (0-10). Mean FEV1 decreased from 79% (SD 22%) to 53% (11%) of the predicted value after pneumonectomy and from 89% (22%) to 74% (18%) after lobectomy. Exercise capacity, measured as the highest work load completed, Wmax, decreased from 78% (25%) to 58% (28%) predicted in the pneumonectomy group and from 77% (21%) to 67% (20%) in the lobectomy group. There was only a weak relation between changes in FEV1 and changes in Wmax (r = 0.54, r2 = 0.30). The slope of the relation between the intensity of dyspnoea and work load or the intensity of dyspnoea and ventilation increased significantly after pneumonectomy, but not after lobectomy. Leg discomfort increased more rapidly when related to work load after both pneumonectomy and lobectomy. After resection dyspnoea was rarely the only limiting factor at maximal exercise. It is concluded that (1) change in FEV1 is a poor predictor of change in exercise capacity after lung resection; (2) pneumonectomy results in a 25% decrease in Wmax and in an appreciable increase in dyspnoea during exercise; (3) lobectomy has little or no effect on Wmax or the intensity of postoperative dyspnoea; (4) after both pneumonectomy and lobectomy leg discomfort makes an important contribution to exercise limitation.
