The solid phase Clq radioimmunoassay was used to detect immune complexes in sera from patients with systemic lupus erythematosus (14/25), rheumatoid arthritis (4/5), vasculitis (5/15), infective endocarditis (2/2), acute rheumatic fever (2/3), pre-eclamptic toxaemia (0/14), lung cancer (3/7), glomerulonephritis (26/98) and renal transplant patients (0/5). The best correlation with disease activity was seen in systemic lupus erythematosus and infective endocarditis where serial immune complex determinations were clearly of value in monitoring therapy. The findings in primary glomerulonephritis indicate only a limited usefulness of the assay in that serum immune complexes were detected in a minority (22/73) of patients with glomerular immune deposits. In particular the data do not support a role for Clq fixing immune complexes in the pathogenesis of membranous glomerulonephritis or in pre-eclamptic toxaemia.

The paper is directed towards those practitioners charged with the responsibility of delivering care pertinent to patients after cardiac valve replacement, coronary artery bypass grafting and surgery for lung cancer. In addition to the postpericardiotomy-syndrome the following complications associated with valve replacement are discussed: thrombotic occlusion or systemic thromboembolism, prosthetic valve endocarditis, mechanical valve dysfunction, postoperative arrhythmias. The patency of aorto-coronary bypass grafts decreases progressively over time and relates directly to improvement in symptoms and in myocardial function. Antiplatelet therapy or anticoagulants are effective in preventing graft occlusion early after operation. The goal of follow-up of patients with curative lung resection for bronchial carcinoma are early detection and treatment of recurrent cancer, metastases or second primary (metachronous carcinoma) tumor, functional cardiorespiratory decompensation and late postoperative complications. It is emphasized that the physician should not consider the patient "cured" once he has undergone cardiac valve replacement, coronary artery bypass grafting or lung resection, but rather should consider him to be the subject of meticulous long-term medical care.

Hematologic dysfunction occurs commonly in patients with malignancy. Over half are anemic, often because of acute or chronic blood loss, marrow involvement by the malignancy, marrow suppressive effects of chemotherapy or radiation therapy, or because of the anemia of chronic disease. Less frequently, anemia may result from red cell aplasia, folate or B12 deficiency, hemolytic processes, or hypersplenism. Occasional patients may become polycythemic because of erythropoietin-producing tumors such as renal adenocarcinomas or cerebellar hemangiomas. Elevation of the white cell count is commonly seen, especially in patients with lung cancer. Monocytosis and thrombocytosis, which may be early signs of an underlying malignancy, are also very common and occur in up to half of patients. Thrombocytopenia is commonly a result of therapy or marrow replacement; a few patients may have a syndrome resembling immune thrombocytopenic purpura. Abnormalities of coagulation are present in many patients, and may lead to superficial or deep venous thromboses, pulmonary emboli, nonbacterial thrombotic endocarditis with arterial emboli, bleeding, or acute disseminated intravascular coagulation. A sound understanding of the potential hematologic complications that can result from the malignant process is essential to the clinician caring for cancer patients.

Use of SM-4300, which is a newly developed human immunoglobulin preparation for intravenous administration, has clinically been evaluated in the patients with severe or intractable bacterial infections. Of total 13 cases of the admitted patients at the 1st department of internal medicine, faculty of medicine, Kyushu university, 10-pneumonia case were associated with blood diseases like acute myelocytic leukemia (AML) and multiple myeloma (MM), and in addition, with other underlying diseases like lung cancer and bronchiectasis, 1 was prosthetic valve endocarditis, 1 cholecystitis associated with pericarditis and 1 fever of undetermined origin (FUO). SM-4300 of 5 g single bolus or 3 daily doses of 2.5 g per day were infused with chemotherapy drugs preceedingly administered for more than 3 days and the results were evaluated; good in 4, fair 4, poor 2 and unknown 3, and the efficacy rate was 40%. Bacteriologically, the results were decreased in 1, persisted 1 and the majority was unknown. Observed were no side reactions nor the changes in clinical examination variables incurred by this drug. It is therefore considered that SM-4300 is of use for the treatment of intractable bacterial infections when used with antibiotics.

Pneumonia due to Rothia dentocariosa is extremely rare: only 1 case of pneumonia due to this pathogen has been reported in an immunocompromised patient with acute myelocytic leukemia. In this report, 2 new cases of Rothia dentocariosa pneumonia are described in 2 patients with lung cancer. This opportunistic pulmonary agent, belonging to the oro-pharyngeal flora, is also known to cause endocarditis in patients with underlying cardiac pathology.

The morphological findings in eight explanted Toronto SPV bioprostheses were described. Clinical records were reviewed for patient information and data regarding the explanted bioprosthesis, all of which were analyzed in detail by gross and histological examination. All valves were also examined radiologically and detailed specimen photographs obtained. When warranted, tissue cultures were taken and special stains for microorganisms obtained. The Toronto SPV bioprosthesis has been used for aortic valve replacement in 270 patients since its introduction in 1991. The follow-up evaluation was 99.5% complete. Eight valves have been explanted: three at surgery and five at autopsy. Patient age ranged from 35 to 69 years, with five male and three female patients. Indications for aortic valve replacement were aortic stenosis in all cases. Implant duration ranged from 5 weeks to just over 6 years (mean 38 months). Early failures (2) were due to infective endocarditis. Two patients died of acute myocardial infarction, related to pre-existing coronary artery disease, and two died from lung cancer. All late explants showed host tissue growth (grade 2-3), with variable extension onto both the proximal and distal suture lines, as well as extension onto the cusps and commissures on the flow and nonflow surfaces. Extension of pannus onto native aortic tissues was seen but did not encroach on the coronary ostia. Tissue degenerative changes were present, as were small tears (type 1) in two valves. Mild calcification was seen in two valves. The Toronto SPV has excellent clinical performance at up to 8 years of follow-up evaluation. In this series, early failures are related to infective endocarditis, and later explants (6 of 8) are associated with mild tissue degeneration and an occasional cusp tear. At up to 5 years, only minimal/mild calcification was seen in two of the eight valves.

A 53-year-old man was admitted to our hospital for back, left shoulder and upper limb pain. Chest radiography and CT on admission revealed right pleural effusion and a focal plate-like thickening of the major fissure. Pleural effusion cytology revealed adenocarcinoma, which was diagnosed as non-small-cell lung cancer with bone metastasis. The patient suffered from DIC, melena and multiple cerebral infarctions during chemotherapy and died on the eighth day of the second course of chemotherapy. Autopsy revealed a pseudomesotheliomatous adenocarcinoma covering the pleura of the right middle lobe, systemic thromboembolism and vegetations on the aortic valves due to nonbacterial endocarditis. Pseudomesotheliomatous adenocarcinoma of the lung, a rare form of lung cancer, complicated with DIC and nonbacterial endocarditis, is reported.

Severe, life-threatening acute upper gastrointestinal bleeding may occasionally occur in patients receiving coumarol prophylaxis for prosthetic heart valves. These patients are exposed to two potential, serious risks: bleeding due to the severe blood loss induced by excessive anticoagulant effect or as a consequence of the cessation of anticoagulation subsequent thrombotic occlusion of the valve and loss of patency. Herein a short case report is presented. The elderly male patient had a prosthetic valve in the aortic position and also suffered from two malignant diseases: chronic lymphocytic leukaemia and a more recently developed lung cancer with metastatic spread into both lungs. The patient had a major gastrointestinal bleed, leading to a sudden fall of haematocrit (0.09), and to a collapse of peripheral circulation due to too excessive a coumarol effect (International Normalized Ratio > 8). An acute left ventricular failure developed during the early period of the emergency blood transfusion, so the correction of prothrombin time by fresh-frozen plasma (due to the large volume requirement) was not feasible. The patient received 50 microg/kg intravenous bolus of NovoSeven (recombinant active factor VII) in an almost desperate situation. The International Normalized Ratio changed to 2.1 in 30 min; bleeding had stopped immediately. There was neither evidence of disseminated intravascular coagulation (in spite of the age and underlying diseases) nor loss of valve patency or infective endocarditis during follow-up. This modest report may call attention to the potential use of recombinant active factor VII in the coumarol-induced severe bleeding episodes of prosthetic heart valve patients.

Certain coagulation disorders can occur in patients with cancer and thromboembolic complications are frequent. We report the case of a 53-Year-old patient with metastatic adenocarcinoma of the lung treated with chemotherapy who presented several cerebral arterial thromboembolic events leading to death a few weeks after the initial diagnosis of cancer. This case illustrates the important role of certain satellite disorders related to coagulation activation: non-bacterial thrombotic endocarditis, disseminated intravascular coagulation, anti-phospholipid antibody syndrome. The role of anticancer chemotherapy as a favoring factor for thromboembolic events is also emphasized in patients with non-small-cell lung cancer.

Non-bacterial thrombotic endocarditis is a recognised complication of malignancy (occurring in 0.3-9.3% of patients in autopsy series), and is most commonly associated with lung cancer. We describe a fatal case of non-bacterial thrombotic endocarditis associated with stage IIIB adenocarcinoma of the lung in which the transoesophageal echocardiogram was negative. Recommendations for management of such cases are given.
