Co-occurrence of Primary Tracheal Diffuse Large B-Cell Lymphoma and Pulmonary AA Amyloidosis: A Unique Case Report.

Primary tracheal diffuse large B-cell lymphoma (DLBCL) is a rare, aggressive, but potentially curable malignancy that is difficult to diagnose and treat. We herein report a 93-year-old Japanese man diagnosed with primary tracheal DLBCL after presenting with progressive dyspnea due to severe upper tracheal stenosis during follow-up for pulmonary amyloidosis. Following the diagnosis, the patient was treated with corticosteroids, followed by R-CHOP chemotherapy, resulting in a therapeutic response.

Acute papillary muscle rupture immediately after ST-segment elevation acute myocardial infarction: A case report.

A 73-year-old woman in cardiogenic shock was referred to our hospital because of papillary muscle rupture immediately after the onset of acute myocardial infarction (MI). She had undergone emergent percutaneous coronary intervention and mitral valve replacement. Serial creatine kinase and creatine kinase MB levels indicated that she had acute phase MI on arrival.

The apolipoprotein B/A1 ratio is associated with reactive oxygen metabolites and endothelial dysfunction in statin-treated patients with coronary artery disease.

Aim: The prognostic significance of the apolipoprotein B/A1 (ApoB/A1) ratio in statintreated patients with coronary artery disease (CAD) is unknown. We aimed to evaluate the association of the ApoB/A1 ratio with oxidative stress and endothelial dysfunction in these patients.

Methods: We enrolled 62 consecutive statin-treated patients who underwent percutaneous coronary intervention (PCI).

Comparisons of detailed arterial healing response at seven months following implantation of an everolimus- or sirolimus-eluting stent in patients with ST-segment elevation myocardial infarction.

Background: The difference of arterial healing response following everolimus-eluting stent (EES) or sirolimus-eluting stent (SES) implantation in patients with ST-segment elevated myocardial infarction (STEMI) has not been compared in detail.

Methods: Thirty-five patients with STEMI were randomly implanted with an EES or SES (23 EES, 12 SES). At seven months, neointimal thickness (NIT) and strut malapposition were evaluated by optical coherence tomography (OCT) and the grade and heterogeneity of neointimal coverage (NIC) and development of intra-stent thrombi were evaluated by angioscopy.

Possible association between non-invasive parameter of flow-mediated dilatation in brachial artery and whole coronary plaque vulnerability in patients with coronary artery disease.

Background: Despite being a relatively widely-used non-invasive parameter of endothelial dysfunction, little is known regarding the relationship between flow-mediated dilatation (FMD) and coronary plaque vulnerability in patients with coronary artery disease (CAD).

Methods: 111 CAD patients (age; 68.9 ± 9.

Effect of 3-month repeated administration of miglitol on vascular endothelial function in patients with diabetes mellitus and coronary artery disease.

Repeated postprandial hyperglycemia may play an important role in the development of atherosclerosis by suppressing vascular endothelial function. Although miglitol suppresses the elevation of blood glucose levels shortly after a meal more than other α-glucosidase inhibitors, the effect of 3-month repeated administration of miglitol on endothelial dysfunction is unknown. Fifty patients with type 2 diabetes and coronary artery disease were enrolled in the present study.
