Sudden onset dyspnea caused by Bochdalek diaphragmatic hernia in an adult: a case report.

Background: Bochdalek diaphragmatic hernia is a developmental defect of the posterolateral portion of the diaphragm. This defect may allow abdominal contents to abnormally occupy the thoracic cavity, resulting in most cases in the compression of the developing lungs. Signs are typically shown during early childhood since the defect is usually present during development.

High microvessel density in pancreatic ductal adenocarcinoma is associated with high grade.

The objectives of this work are to study angiogenesis in pancreatic ductal adenocarcinoma using computerized morphometric and image analysis and to compare the microvascular density in intratumoral and peritumoral areas and normal pancreatic tissue. Microvascular density was analyzed in 60 cases of pancreatic ductal adenocarcinoma and 30 samples of normal pancreatic tissue using an avidin-biotin immunoperoxidase technique with an anti-CD31 antibody. Microvascular density (MVD) was analyzed through digital microimaging and computerized analysis.
