Case Reports
Treatment of bronchorrhea by corticosteroids in a case of bronchioloalveolar carcinoma producing CA19-9.
A case of gastrointestinal cancer-associated antigen (CA19-9)-positive bronchioloalveolar carcinoma accompanied by bronchorrhea and respiratory failure successfully treated with corticosteroids is reported. The patient was treated with pulse methylprednisolone at a dose of 1,000 mg/day for three days, followed by oral prednisolone (60 mg/day). ⋯ The levels of CA19-9 in the serum and the sputum were extremely high and an immunocytochemical study showed that the tumor cells were stained by CA19-9 antibody. This case demonstrates the therapeutic value of corticosteroids in the treatment of bronchorrhea in subjects with bronchioloalveolar carcinoma.

There is clinical and pathological evidence of thrombosis in pulmonary vessels of patients with chronic obstructive pulmonary disease (COPD). The purpose of this study was to investigate the presence of hypercoagulability and determine the extent of this abnormality in COPD patients. ⋯ Our results showed an enhanced prothrombotic process in COPD patients, which could potentially account for the increased thrombosis in pulmonary vessels in these patients.

Review Case Reports
Two cases of Sjögren's syndrome with multiple bullae.
Here, we report two rare female cases of Sjögren's syndrome with multiple bullae, involving a 66- and a 51-year-old. Neither had any obvious pulmonary complaint. Chest radiographs and high-resolution CT (HRCT) scans showed interstitial linear and nodular opacities and multiple bullae. ⋯ In the first case the bullae decreased in size with corticosteroid treatment. Airway narrowing due to peribronchiolar mononuclear cell infiltration causes a check-valve mechanism, which may lead to bullae formation. Although a rare occurrence, it is important to recognize that cystic or bullous lung disease can accompany Sjögren's syndrome.

Case Reports
Systemic lupus erythematosus complicated by cytomegalovirus-induced hemophagocytic syndrome and colitis.
Here, we report a case of systemic lupus erythematosus (SLE) complicated by cytomegalovirus (CMV)-induced hemophagocytic syndrome (HPS) and colitis. A 44-year-old woman with SLE was treated with corticosteroid and cyclophosphamide for lupus nephritis. Although her lupus nephritis improved, fever, progressive pancytopenia and intestinal bleeding were observed. ⋯ Furthermore, a large number of CMV antigen-positive leukocytes was detected, suggesting an active CMV infection. CMV infection is serious in compromised hosts. Therefore clinicians should be aware of the clinical settings in which this infection can arise and the target organs potentially affected in order to initiate the appropriate intervention.

Review Case Reports
Retroperitoneal fibrosis associated with membranous nephropathy effectively treated with steroids.
Corticosteroids were successfully used to treat a 66-year-old man with retroperitoneal fibrosis (RPF) and previously diagnosed membranous nephropathy. Proteinuria was noted at the age of 51 years, and membranous nephropathy was diagnosed by renal biopsy. Ten years later, he presented with right hydronephrosis and renal dysfunction, and was diagnosed as having RPF based on the typical diagnostic imaging findings. ⋯ The hydronephrosis recurred three years later, but corticosteroids were again effective in improving ureteral obstruction. This was a rare case of recurrent RPF with membranous nephropathy in which steroid therapy was effective in treating pleural effusion and hypergammaglobulinemia during the clinical course. This case suggests that an immunological disorder is involved in the pathogenesis of RPF.
