A patient with acute lymphoblastic leukemia had an unusual prodrome, including clinical features of "hypereosinophilic syndrome," pulmonary infiltrates, and bilateral spontaneous pneumothorax, which preceded the onset of leukemia by four months. The mechanism for the production of eosinophilia may have been related to the production of eosinopoietic factors by the leukemic cells.

Patients with pulmonary tuberculosis treated in 4 sanatoria in Niigata prefecture during the period from 1941 to 1961 were followed up. Of 2,756 patients, 1,193 responded and sent us effective information. However, 1,224 did not come into contact because of changed and unknown adress, 326 did not respond, and 13 were omitted because of incomplete answers. Of 1,193 effective responders, 568 had been treated by artificial pneumothorax (the pneumothorax group), and 552 had been treated by the other measures than pneumothorax (the control group). There were 65 deaths in the pneumothorax, group, and 40 deaths in the control group. No deaths from chest malignancies were reported in the pneumothorax group, while 4 chest malignancies in the control. In this survey, no evidence of increased frequency of chest malignancies including leukemia following multiple fluoroscopies during artificial pneumothorax was detected.

Pulmonary cavitation and pneumothorax may complicate severe cases of Pneumocystis carinii pneumonia. Both complications likely result from tissue necrosis, although how such injury occurs is unknown. To investigate mechanisms of tissue destruction in P carinii pneumonia, histochemical, immunocytochemical, and electron microscopic studies were conducted in pulmonary wedge resections or autopsy specimens from patients with the acquired immunodeficiency syndrome (n = 7) or leukemia (n = 2). Tissue invasion, defined as Pneumocystis organisms in the interstitial compartment, was present in eight of nine cases. Organisms were found in alveolar septa (eight cases), pleura (six cases), and vessel walls (two cases). All cases with tissue invasion exhibited regional necrosis as well as extensive invasion of apparently viable parenchyma. Pulmonary cavitation occurred in seven of eight cases with tissue invasion, and six of these patients developed pneumothoraces. Despite extensive tissue invasion and necrosis there was little host inflammatory or stromal response. Ultrastructurally, both the tissue-invasive and intra-alveolar organisms were predominantly of the trophozoite form; they were present in much greater numbers than suggested by routine silver stains (which detect only cysts). Immunocytochemical techniques, which detect both trophozoite and cyst forms, were much more sensitive than silver stains. These results indicate that extensive tissue invasion by P carinii can occur in severe P carinii pneumonia. We hypothesize that such invasion is an important step in the development of pulmonary necrosis, cavitation, and pneumothorax.

Thirty pulmonary infiltrates in 26 patients were investigated by bronchoalveolar lavage. Sixteen of the patients were on therapeutic immunosuppression for renal disease or transplant and 10 had leukaemia, lymphoma, or allied conditions. A rapid specific diagnosis was made in 21 (70%) episodes by cytological examination of the fluid and in 28 (93%) by a combination of cytology and microbiology. No complications from haemorrhage or pneumothorax ensued. Pneumonia due to Pneumocystis carinii was the most common diagnosis (27%), but opportunistic infections from cytomegalovirus, candida, aspergillus, zygomycetes, and acid fast bacilli were also identified by cytology. Two episodes were caused by occult pulmonary haemorrhage and five patients had malignant infiltration of the lung from leukaemia, myeloma, Hodgkin's disease, and lymphoplasmacytoid lymphoma. In two of these there was also evidence of infection. In seven cases with non-diagnostic cytology infections due to Staphylococcus aureus, Pseudomonas aeruginosa, pneumococcus, micrococcus, and Aspergillus fumigatus were identified on culture. In two patients (7%) no specific diagnosis was established by lavage: one had serological evidence of legionella infection and the second had P aeruginosa septicaemia. Twelve (75%) of the renal patients and six (60%) of those with leukaemia, lymphoma, and allied conditions recovered.

A series of 51 consecutive unexplained pulmonary infiltrates were reviewed retrospectively, in a group of 48 patients in whom invasive procedures were performed. Fifty-two percent of these patients had leukemia or lymphoma and 40% had solid tumors. All patients had lung tissue obtained premortem either by transbronchial biopsy through the flexible fiberoptic bronchoscope or by open lung biopsy. There was a 27% complication rate in these invasive procedures including bleeding, pneumothorax, and ventilatory support. Infectious agents were found in only 13 cases (25%) with a mortality rate of 62%. The pathologic finding of the underlying malignant disease or organizing pneumonia portended a poor prognosis with 100% and 80% mortality, respectively. Twenty-one patients had biopsy tissue revealing only nonspecific pathologic changes and were associated with the lowest mortality (19%). It was found that 50% of the solid tumor patients with unexplained pulmonary infiltrates had nonspecific pathologic changes. The biopsy findings resulted in a change in the therapy in 29% of the cases and in 19% of the cases the subsequent change in therapy resulted in marked improvement. The lung biopsy is useful to diagnose treatable infectious disease, as well as for prognostic guidance in caring for critically ill compromised patients.

Among 1,047 women fluoroscopically examined in average of 102 times during pneumothorax therapy for tuberculosis and followed up to 45 years (average = 27 yr), no increase in the total number of cancer deaths occurred when these women were compared to 717 women who received other treatments [relative risk (RR) = 0.8]. However, elevated risks of mortality from stomach cancer (RR = 2.3), rectal cancer (RR = 3.8), breast cancer (RR = 1.2), lung cancer (RR = 1.8), and leukemia (RR = 1.2) were observed, but none was statistically significant and all were based on very small numbers of deaths. These increases were balanced by decreases of genital cancer (RR = 0.2), pancreatic cancer (RR = 0.9), lymphoma (RR = 0.6), and all other cancers (RR = 0.1). Average cumulative absorbed doses were 110 rads for the lungs, 33 rads for the trunk, 13 rads for the active bone marrow, and 7 rads for the stomach. The following upper levels of excess risk could be excluded with 95% confidence: 3.5 deaths/10(6) woman-year (WY)-rad for lung cancer, 4.8 deaths/10(6) WY-rad for lymphoma, and 12 deaths/10(6) WY-rad for leukemia. These findings indicated that the carcinogenic effect of multiple low-dose X-ray exposures was not greater than that currently assumed.

Fifty-six fibreoptic bronchoscopies were performed on 42 patents with Hodgkin's disease, lymphoma, or leukaemia and pulmonary complications which did not respond to conventional antibiotics. All these patients had received chemotherapy, radiotherapy, or both for the treatment of their underlying conditions. Twenty-two bronchoscopic procedures were complicated by thrombocytopenia and neutropenia, requiring platelet transfusion before bronchoscopy, and many patients were hypoxaemic. Visual examination of the tracheobronchial tree, alveolar lavage, bronchial brushing, and transbronchial biopsy were carried out as approximate. Three patients had minor pulmonary haemorrhage, and three developed a pneumothorax after transbronchial biopsy. A specific diagnosis was obtained in 14 of 18 patients (78%) with diffuse chest radiographic abnormalities, in seven of 11 patients (64%) with lobar or segmental (focal) abnormalities, in two of eight patients with small (local) lesions, and in three of five patients with hilar abnormalities. In only three patients were infections diagnosed. It is concluded that fibreoptic bronchoscopy is a useful and safe diagnostic procedure in this situation but its value depends upon the type of radiological abnormality.

Case records of 9 dogs and 5 cats with eosinophilic effusions were reviewed. The animals ranged from 11 months to 13 years old. Seven animals had pleural effusions, 5 had peritoneal effusions, and 2 had pleural and peritoneal effusions. Neoplasia was confirmed in 6 animals and suspected in 1. Eosinophilic pleural effusion was diagnosed 2 days after pneumothorax developed as a consequence of thoracic tube placement in a cat, and pneumothorax was diagnosed in another cat with eosinophilic peritoneal effusion. Other abnormalities seen in 1 or 2 animals associated with eosinophilic effusion were radiographic signs of interstitial or peribronchial pulmonary infiltrates, a history of allergic respiratory tract and skin disease, intestinal lymphangiectasia and lung lobe torsion, chylothorax, bite wounds causing intestinal perforation, and feline leukemia virus infection. Based only on the protein concentration of the effusion, 7 effusions were classified as transudates and 7 were classified as exudates. Five of the 14 animals had eosinophilia (> 1,200 eosinophils/microliters); 3 of these animals had neoplastic disease. Mean eosinophil count in blood samples was not significantly different between animals with neoplasia and those without. Eosinophil counts in blood samples were not linearly related to counts in effusions; however, in some animals the number of eosinophils in the effusion was much higher than the eosinophil count in blood, suggesting concentration of eosinophils in the effusion.

We report the pulmonary computed tomography (CT) findings in three patients with acute promyelocytic leukaemia who developed the retinoic acid syndrome following all-trans retinoic acid (ATRA) therapy. The most consistent CT findings were small, irregular peripheral nodules in the lung fields and pleural effusions. Two of the patients also showed evidence of reticular and ground glass shadowing as well as abnormal anterior mediastinal soft tissue. We report for the first time an association between ATRA and pneumothorax. We conclude that routine CT scanning may provide a sensitive means of early detection or monitoring of the syndrome and thereby may facilitate its management.

We are presenting a 16 months old boy, who has been previously developing normally, physically very active, and who suddenly developed right-sided pneumothorax with infiltrations in both lungs, initially defined as inflammatory. After placing suction drainage of the pleural cavity and antibiotic administration the child's condition improved quickly. The infiltration changes still remained in lungs arousing a suspicion of fibrocystic changes. During an attempt at changing the drainage into a water one, the symptoms of pneumothorax with hypertension increased again. A minithoracotomy with an edge resection of segment 4 and pleurectomy were performed, relating to the histopathological test of the sample, Largenhans' cell histiocytosis was diagnosed. The symptoms of diabetes insipidus appeared. The treatment according to the program DAL-HX83/90 modified by the Polish Group for Leukaemia and Malignant Lymphoma was introduced. During the treatment inducing remission a pneumothorax occurred two more times.
