RESUMEN
We report a very unusual case of endobronchial involvement of eosinophilic inflammation. A 58-year-old woman visited our clinic complaining of cough. A chest computed tomography scan showed a poorly enhancing mass compressing both main bronchi in the subcarinal area. Bronchoscopy also showed stenosis of the two main bronchi with irregular mucosal thickening. A bronchoscopic endobronchial mucosal biopsy revealed eosinophilic inflammation without evidence of malignancy. The subcarinal mass disappeared after systemic steroid treatment. This is the first report of mass-forming eosinophilic infiltration involving the central airway mimicking primary lung cancer.

Primary autoimmune myelofibrosis, the development of which is not preceded by a well-defined autoimmune disease, has recently been defined as a distinct clinicopathologic syndrome. We report herein a case of a 68-year-old woman who was diagnosed with primary autoimmune myelofibrosis and present a review of the literature. The patient manifested peripheral pancytopenia, was positive for autoantibodies, and developed myelofibrosis with no preceding autoimmune or hematologic disorders. Her condition was dramatically improved after administration of prednisolone.

BACKGROUND/AIMS: Preoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) is a useful predictor of postoperative cardiovascular complications. The present study investigated whether blood NT-proBNP values are suitable for predicting postoperative cardiovascular complications after non-cardiac surgery in elderly patients showing normal left ventricular (LV) function on preoperative echocardiograms. METHODS: This study was performed by analyzing the medical records of elderly patients referred to the cardiology department for the purpose of assessing their cardiac function before orthopedic surgery. Of the patients who underwent echocardiography and NT-proBNP assessment simultaneously, 275 patients aged > or = 70 years and with an LV ejection fraction of > or = 55% were included in the study. RESULTS: Major adverse cardiac and cerebrovascular events (MACCEs) occurred in 33 (12%) of the 275 patients, and the NT-proBNP concentration was higher in patients with complications than in those without complications (1,904.20 +/- 2,300.23 vs. 530.58 +/- 882.27 pg/mL, p 80 years (odds ratio, 2.313; p = 0.047) and an increased blood NT-proBNP concentration (odds ratio, 3.189; p = 0.009) were independent risk factors for the prediction of MACCEs. CONCLUSIONS: Although elderly patients scheduled to undergo non-cardiac surgery may show normal LV systolic function on echocardiography, measurement of their preoperative blood NT-proBNP concentration is useful for predicting MACCEs occurring after non-cardiac surgery.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that is clinically heterogeneous and affects multiple organs particularly the kidney. Lupus nephritis is a common and severe manifestation of SLE in which immune-mediated inflammation can lead to permanent damage within the kidney, resulting in end stage renal failure. Recently a renal biopsy showed lupus nephritis on a 40-year old female without any other features of SLE such as clinical symptoms and autoantibodies including antinuclear antibody and anti-dsDNA. The renal biopsy showed that histopathological change of global and segmental sclerosis of glomeluri, diffuse proliferative nephritis with crescent formation compatible with class IV lupus nephritis. She was treated with systemic corticosteroids and pulse cyclophosphamide, followed by mycofenolate mofetil. During two years of follow-up, there have been no clinical or laboratory findings to meet the diagnostic criteria of SLE, suggesting that isolated lupus nephritis could occur without SLE.
