We report the result of treatment for thirty-two patients whose chief complaint was hemoptysis and represent the therapeutic guide line for hemoptysis. In thirty-two cases, there were twenty men and twelve women and average of age was fifty-two years old. Twenty-nine of them were chronic lung diseases such as tuberculosis and bronchiectasis and only three cases have malignant tumors. Two of them recovered with conservative therapy and bronchial arteriography (BAG) have been performed in thirty patients in order to determine the bleeding foci, BAG was failed in two cases, but these two cases have been recovered with following up, BAG was succeeded in twenty-eight cases and twelve cases of them could not been determined the bleeding foci by angiography and could be controlled using hemostatic and antibiotic agents. Embolization of bronchial arteries with gelatin sponge have been performed in sixteen cases and made success in eleven cases. In ten of these cases, BAE was effective less than two times. Only one of silicosis with restrictive lung function was considered contraindication of surgery and recovered by three times of BAE. Four cases of five uneffective BAE (rebleeding after two times of BAE) have been treated by operation in good course. But one case complicated with WPW syndrome has died because of aspiration pneumonia without operation. In our institute, the rate of operation for hemoptysis was low as 13% of thirty-two cases. In order to consider the indication of surgery, bronchial arteriography was essential to determine bleeding foci and BAE was effective in over 80% of hemoptysis.(ABSTRACT TRUNCATED AT 250 WORDS)

Legionnaires' disease in a 37-year-old male who had had silicosis was reported. He was admitted because of dyspnea. The chest X-ray film and CT scan showed infiltrative shadow and swelling of mediastinal lymph nodes. Open lung biopsy was done and Legionella pneumohila was detected. REP and EM were started and infiltrative shadow of X-ray was disappeared. Pleuro-pneumonectomy and thoracoplasty were performed because of hemoptysis and postoperative empyema. The patient is now well.

Terlipressin (Glypressin) is a "pro-hormone"; after intravenous injection the glycyl radicals are slowly cleaved by enzymatic action, liberating vasopressin. We have assessed the efficacy of terlipressin in the treatment of severe hemoptysis. The study was performed on 20 patients: in 5 cases there was very copious hemoptysis and in 15 cases there was repeated hemoptysis of lesser volume. The cause was distributed as follows: 6 cases of neoplasms, 5 were sequelae of tuberculosis, bronchial dilatation 2 cases, pneumonia with abscess 2 cases, chronic airflow obstruction (COPD) 2 cases and 3 cases of silicosis. The treatment consisted of a slow intravenous injection of 2 mgm 4 times per day (9 patients), then in 11 patients an injection of 2 mgm at the time of acute episodes followed by 1 mgm every 6 hours. The patients received an average of between 15 and 20 mgm of the product for a treatment lasting over 5 days at the maximum. The results were as follows: total success 12 cases; partial success (a reduction to at least one-third of the initial hemoptysis): 5 cases; failure: 3 cases. The failures were linked in two cases to neoplastic disease and in one case there was an intolerance to the drug which did not allow the treatment to be pursued.(ABSTRACT TRUNCATED AT 250 WORDS)

A patient, 37 years old in 1966, presented hemoptysis and an excavated lesion of left upper lobe; there were no acid-fast bacilli in the sputum, but he was considered as having tuberculosis. After one year of treatment, the lesion had progressed and was removed surgically; pathologic diagnosis was silicosis. During the following years, three excavated lesions developed in the controlateral lung. When seen in 1979, the patient had consolidation of the whole right upper lobe and an excavated mass of right lower lobe. Amyloidosis was suggested; the pathologic sections of 1967 were reviewed and confirmed amyloidosis.

For the management of severe haemoptysis we have developed a double-lumen, bronchus-blocking catheter that can be introduced through the working channel of a standard fibrebronchoscope. We wondered whether this catheter would be suitable to control pulmonary haemorrhage in clinical practice. Over a period of 36 months, 30 of these catheters were used in 27 patients with moderate and massive pulmonary bleeding from various lesions. Underlying diseases were: malignancies (11), vascular deformities (5), tuberculosis (4), silicosis (2), carcinoids (2), silicosis (2), endometriosis (1), bronchiectasis (1). In 26 cases, the transbronchoscopic balloon tamponade was successful. In one patient, tumour growth close to the carina prevented securing of the balloon and double-lumen tube intubation was required. There were only minor complications attributable to the balloon. With the catheter in place for up to seven days, patients underwent surgery, received radiation, chemotherapy, drug treatment or bronchial arterial embolization. In conclusion, we found this double-lumen, bronchus-blocking device safe and the technique practicable to control pulmonary haemorrhage.

A 63-year-old man was referred to our hospital for rapid deterioration of his renal function. He had worked as a metal founder for more than 40 years, and had been diagnosed as having silicosis. Laboratory data on admission showed severe anemia, thrombocytopenia, and end-stage renal failure (BUN 88.8 mg/dl, serum creatinine 9.0 mg/dl). Myeloperoxidase anti-neutrophil cytoplasmic antibody(MPO-ANCA) was also detected in his sera. On the next day after admission, he complained of sudden dyspnea and hemoptysis. Mechanical ventilation with pure oxygen was insufficient to improve hypoxia without concomitant use of percutaneous cardio-pulmonary support(PCPS) and continuous hemofiltration(CHF). We diagnosed his condition as MPO-ANCA-associated rapidly progressive glomerulonephritis with diffuse alveolar hemorrhage. Treatment with plasmapheresis, pulse methylprednisolone and pulse cyclophosphamide effectively improved his hemoptysis as well as chest X-ray findings and blood gas analysis. However on his later clinical course, he was complicated with superimposed complex infection and passed away. Autopsy findings showed crescentic glomerulonephritis in the kidneys and silica nodules in the lungs. Recently it has been postulated that some relationship exists between ANCA-associated(especially MPO-ANCA-associated) glomerulonephritis and silica exposure. The reported cases of glomerulonephritis in the patients with silica exposure showed a rapidly progressive clinical course and pauci-immune necrotizing crescentic glomerulonephritis in their histology. Gregorini et al. reported that 12 of 37 (32%) male patients with RPGN had either silicosis or significant silica exposure, and 7 of 8 patients examined were ANCA-positive(6 of 7 were MPO-ANCA-positive). Therefore silica seems to cause glomerulonephritis by disrupting the immune response. Including this case mentioned above, we have experienced 10 cases of MPO-ANCA-associated glomerulonephritis, at least 3 cases out of which had suffered from silicosis in the past(30%). These results indicate that silicosis should be considered a relevant pathogen of MPO-ANCA-associated glomerulonephritis beyond the race.

Inhalation of dusts is an important cause of interstitial lung disease in the tropical countries such as India. While dusts of organic origin, such as the cotton dust causing byssinosis, generally cause bronchial or bronchiolar involvement and hypersensitivity pneumonitis, inorganic metallic dusts cause progressive pulmonary fibrosis. Silicosis, coal workers' pneumoconiosis, and asbestosis are the three most commonly recognized forms of pneumoconiotic pulmonary fibrosis. Pulmonary tuberculosis is an important complication seen in up to 50% of patients of silicosis in some reports from India. The presentation is generally chronic, although acute and accelerated forms of silicosis are known when the exposures are heavy. Breathlessness, dry cough, and general constitutional symptoms are commonly seen. Patients with silicotuberculosis or other forms of infection may also have significant expectoration, hemoptysis, fever, and rapid progression. Respiratory failure and chronic cor pulmonale occur in the later stages. The diagnosis is easily established if the occupational history is available. Dense nodular opacities on chest roentgenograms, which may be large in patients with massive pulmonary fibrosis, are characteristic. Emphysematous changes generally appear in advanced stages or in patients who smoke. Bronchoalveolar lavage and/or lung biopsy may occasionally be required to establish or exclude other causes of interstitial lung disease. Treatment is largely palliative, although a variety of drugs including corticosteroids and procedures such as whole lung lavage have been tried. None of these methods has yet been found successful in the treatment. Preventive safety steps, including removal of the patient from the site of exposure, are the only effective strategies to control disease progression.

The cases of 6 patients (4 men, 2 women) with antisynthetase syndrome are reported. The mean age was 60 years and the most frequent symptom was increasing dyspnea (4 patients). One of the remaining 2 patients had hemoptysis and the last was asymptomatic. Systemic symptoms included Raynaud's phenomenon (2 patients), arthritis in hands (3) and muscle impairment (4). Chest films showed linear interstitial infiltrates of varying severity in 5 patients; the patient without such infiltrates also suffered silicosis. Functional assessment showed restrictive impairment in 4 patients; of the remaining 2 patients, 1 had chronic obstructive pulmonary disease and 1 had normal function. The antisynthetase antibody (ASAB) detected was anti-Jo-1 in 4 cases, anti-PL-12 in 1 case, and unidentified in 1 case. The course of disease was satisfactory for 5 patients. ASAB analysis is useful for studying idiopathic interstitial lung disease.

Over a period of approximately 30 years we have compared the frequency of Miner's phthisis in the coal mining areas of Aachen and the Ruhr area of Essen and have investigated a total of approximately 600 lungs with silicosis. In cases of silicosis grades II-III and III we found liquefaction in 36% of the callosities but in cases of silicosis I-II and II in only 4-7%. Liquefaction of callosities, or phthisis atra, was found slightly more often in the Ruhr area than in the area of Aachen. If the liquefied silicotic material is expectorated from the bronchial tubes, a cavern-like cavity develops in the lungs, which clinically can often not be differentiated from a tuberculotic cavern. Sometimes silicotic material is transported via the blood vessels and dust particles could often be found microscopically in the liver, spleen or kidneys. In one patient we found silicotic material coming from the bronchial veins with development of arterial embolisms in peripheral arteries of the extremities and brain. The pathogenesis of callosity liquefaction is a consequence of disruption of the blood supply to the surrounding areas of the callosities. In some cases blood vessels in the centre of the callosities are destroyed so that the patient dies after severe haemoptysis.

Most broncholiths are related to infection with fungus or tuberculosis and they involve the lymph nodes; those cases that are caused by silicosis are rarely seen. Broncholith might lead complication such as bronchial rupture into the mediastinum, which can result in hemoptysis, cough, repeated pneumonia and so on. Flexible bronchoscopy plays an important part in the diagnosis of broncholithiasis, but its therapeutic application in the clinical setting is controversial. We report here on two cases of broncholith removal without complication with the use of a balloon catheter and tripod forceps using flexible bronchoscopy.
