Nasogastric aspirate predicts high-risk endoscopic lesions in patients with acute upper-GI bleeding.
Active upper-GI bleeding (spurting or oozing) or a visible vessel at endoscopy are high-risk lesions that predict recurrence of bleeding. The aim of this study is to determine whether nasogastric aspirate predicts the presence of high-risk lesions. ⋯ Nasogastric aspirate is useful in predicting high-risk lesions. Whether it can be used to determine which patients would benefit from earlier endoscopy deserves further study.

Accuracy of EUS criteria and primary tumor site for identification of mediastinal lymph node metastasis from non-small-cell lung cancer.
EUS with FNA is useful for staging non-small-cell lung cancer. However, benign mediastinal adenopathy is common. The aims of this study were to identify clinical factors, especially primary tumor location, and EUS lymph nodal characteristics predictive of aortopulmonary window and subcarinal lymph node metastases of non-small-cell lung cancer. ⋯ Although tumor location and EUS lymph nodal characteristics are associated with malignant involvement of lymph nodes, the accuracy of these predictors does not obviate the need for cytologic evaluation. EUS with FNA should be performed for all lymph nodes when an abnormal finding will alter management.
