Four children aged 31/2 to 13 years, who developed allergic alveolitis as a result of antigenic exposure in a domestic situation are described. The clinical symptoms consisted of gradual onset of increasing dyspnoea, chronic cough and weight loss. Lung function tests showed characteristic reduction in vital and diffusion capacity. Serologically, antibodies against animal antigens were demonstrated in all patients. Radiologically there were pronounced reticular changes in both lungs affecting mostly the middle and lower zones. Occasionally there were miliary and sometimes confluent shadows. In differential diagnosis, virus infections, pneumocystis carinii, fungus infections, dermatomyositis, sarcoidosis and tuberculosis had to be considered. Apart from a short course of steroid treatment, it is necessary to make certain that the children are no longer exposed to the causal antigen. Under these conditions the prognosis is good, but otherwise the disease, as in adults who are continuously exposed to the antigen, results in pulmonary fibrosis.

Serum FDPs were investigated in 30 healthy and 95 patients with pulmonary thrombembolia, not-stabilized angina pectoris, myocardial infarction, rheumatism, rheumatoid arthritis, lupus erythematodes and dermatomyositis. FDPs are determined by hemagglutination inhibition according to Merskey. They are found in the sera of the healthy in average values of 3.73 mkgr/ml. The highest average values in the first 24 h were found in case of pulmonary thrombembolia up to 106.64 mkgr/ml, followed by rheumatoid arthritis 26.3 mkgr/ml, myocardial infarction with complication 22.4 mkgr/ml, rheumatism +5.58 mkgr/ml, not-stabilized angina pectoris 5.5 mkgr/ml; and noncomplicated myocardial infarction 4.3 mkgr/ml. By the third day of the disease FDP in pulmonary thrombembolia decreased, whereas a negligible elevation was observed in case of non-complicated myocardial infarction. The results were interpreted as well as the cause for the presence of the mentioned products in those groups of diseases. FDP determination is recommended as a routine method in case of: diagnosis of pulmonary thrombembolia, differentiation of myocardial infarction with or without complications, differentiation of pulmonary thrombembolia from myocardial infarction in emergency states, progressing with chest pain, collapse phenomena, dyspnea and establishment of the activity of the process of rheumatoid arthritis. FDP determination in stenocardia and rheumatism is not expedient.

Interstitial pneumonitis may be the presenting manifestation of polymyositis-dermatomyositis, or may occur later in the evolution of the disease. The clinical picture is characterized by non-productive cough, dyspnea and hypoxemia. The chest radiograph demonstrates interstitial infiltrates with predilection for the lung bases, often with an alveolar pattern in addition. The histopathologic features are those of organizing and interstitial pneumonitis and pleuritis, with variable fibrosis. In the present series, the patients with mixed alveolar and interstitial infiltrates on chest radiograph and organizing pneumonia and bronchiolitis obliterans in addition to interstitial pneumonitis. In one patient evolution from pulmonary inflammation to interstitial fibrosis was demonstrated. The etiology of primary lung disease in PM-DM is not known, but cell-mediated autoimmunity to an unidentified component of lung tissue is suggested. Including the present series, 50 percent of patients have responded favorably to corticosteroids with decreased dyspnea, clearing of the chest radiograph and improved pulmonary function tests.

Interstitial lung disease (ILD) has been recognized as a manifestation of polymyositis or dermatomyositis (PM/DM). Patients with PM/DM with anti-Jo-1 antibody had a higher incidence of ILD. Thirty-five patients with PM/DM were studied the antibodies. Six (16.1%) were found to have them. ILD occurred in all 6 anti-Jo-1 positive patients, as opposed to 10 (34.5%) of 29 anti-Jo-1 negative patients. Only 2 cases of undifferentiated connective tissue disease among 1320 patients with various kinds of collagen vascular diseases other than PM/DM were positive for anti-Jo-1 antibody. These two patients also had lung involvement. Among six PM/DM patients with anti-Jo-1 antibody, dyspnea preceded proximal muscle weakness in three patients. In one case, the anti-Jo-1 antibody had been detected one month prior to the onset of myositis. Anti-Jo-1 antibody is a useful marker for PM/DM with ILD.

The clinical and autopsy records of 65 patients with either polymyositis (24) or dermatomyositis (41) and pulmonary disease were reviewed. Pulmonary symptoms were recorded in 43 of the cases and included dyspnoea in 31, cough in 23, and chest pain in six. Interstitial lung disease was noted at autopsy in 27 patients; almost half of these had arthritis. Bronchopneumonia was found in 35 patients, 31 of these had received prednisone. Dysphagia was present in a similar proportion of patients with and without pneumonia. Pulmonary vasculitis was seen in five patients; pulmonary symptoms, arthritis, and raised erythrocyte sedimentation rate were present in four of these cases and all five had associated interstitial lung disease. Other pulmonary manifestations included pulmonary oedema, primary pulmonary malignancy, diffuse alveolar damage, fibrinous pleuritis, pulmonary emboli, and diaphragmatic atrophy. The mean survival after disease onset was 29 months but was much less for those with interstitial lung disease and pulmonary vasculitis.

Systemic lupus erythematosus, polymyositis/dermatomyositis, connective tissue disease, and polyarteritis nodosa are the collagen vascular diseases (CVDs) most likely to mimic pneumonia. All can be associated with an acute illness characterized by fever, cough, dyspnea, pleural symptoms, and an abnormal chest roentgenogram. Recognition of the CVD-associated pulmonary process requires sophisticated serological testing and chemical pleural fluid analysis coupled with the exclusion of pulmonary infection and pulmonary embolization. This review emphasizes the clinical characteristics of these CVDs, the diagnostic tests most helpful in recognizing them, and the differential diagnosis of pleuroparenchymal disorders that occur in these patients.

A sixty-two-year-old woman with chronic dermatomyositis (DM) receiving steroid monotherapy developed coronary artery stenosis. She had lung fibrosis and complained of dyspnea, but no ischemia was suggested by electrocardiogram. Ateriographic findings and clinical symptoms of coronary artery disease in DM have not been previously reported.

To assess the feasibility of treatments for patients with small cell lung cancer (SCLC) showing a poor performance status (PS, Eastern Cooperative Oncology Group; ECOG 3 or 4), we retrospectively reviewed the outcome for 13 SCLC patients showing poor PS treated at the National Cancer Center Hospital between January 1984 and May 1994. The main factors which contributed to poor prognosis were superior vena cava (SVC) syndrome, massive pleural effusion, tracheal stenosis due to lymph node swelling, pericardial effusion and pulmonary fibrosis (causing dyspnea in combination), brain metastasis resulting in neurological disturbance, cachexia, Eaton-Lambert syndrome causing muscle weakness, retroperitoneal lymph node metastasis causing abdominal pain, peritoneal effusion due to abdominal lymph node swelling, vertebral metastasis causing paraplegia, and dermatomyositis/polymyositis (DM/PM) causing muscle weakness. All of the patients received chemotherapy with or without radiotherapy. The PS of 8 patients improved with treatment, but no improvement was seen in 5. We analyzed these 13 patients and considered the treatments for those with poor PS. Chemo-radiotherapy was tolerable in SCLC patients showing PS 3, and improved their PS if severe conditions or combined disease did not arise concurrently. It was further suggested that PS 4 patients with severe conditions or combined disease should not be given the treatments.

A 60-year-old man with dermatomyositis was admitted to our hospital because of dyspnea and hypertension. He had high fever and convulsive seizures after admission. Laboratory examinations showed hemolytic anemia, thrombocytopenia, and renal failure. A clinical diagnosis of thrombotic thrombocytopenic purpura (TTP) was made. He failed to respond to plasma exchange therapy, pulse therapy with methylprednisolone, high-dose gamma-globulin therapy, and antiplatelet therapies with ticlopidine, dipyridamole and a prostacyclin analog of beraprost sodium. He died on his 17th day in hospital. Autopsy examination revealed widespread microthrombi in his kidneys, lungs, spleen, and intestine. Only seven cases of dermatomyositis or polymyositis complicated by TTP have been cited in the literature. TTP was fatal in 6 of these 7 cases. Early diagnosis and prompt treatment may improve the outcome of TTP patients with dermatomyositis. Dermatologists should keep in mind that TTP occasionally arises as a serious complication of dermatomyositis.

We studied clinicopathological characteristics of interstitial pneumonia associated with amyopathic dermatomyositis. The subjects comprised two men and three women, and their mean age was 58.2 years. All subjects had cruptions specific for dermatomyositis, but had no signs of myositis. They all presented with acutely or subacutely developed coughing and dyspnea. Results of tests for anti-Jo-1 antibody were negative in all cases. Chest X-ray films showed infiltrations or streaky shadows, or both in the middle and lower lung fields. Analysis of bronchoalveolar lavage fluid revealed abnormally high percentages of lymphocytes and neutrophils. In one patients a specimen obtained by open lung biopsy showed homogeneous cell infiltrations in alveolar septa and regional alveolar damage. That patient was successfully treated with cyclosporin and corticosteroids in early phase of the disease. The other four patients received immunosuppressive agents after respiratory failure developed. All four died despite having received high-dose corticosteroid and immunosuppressive therapy. Examination of autopsy specimens showed diffuse alveolar damage.
