Can endosonographers evaluate on-site cytologic adequacy? A comparison with cytotechnologists.

Background: On-site determination of cytologic adequacy increases the accuracy of EUS-guided FNA (EUS-FNA); however, on-site cytotechnologists are not available to all endosonographers. We hypothesize that experienced endosonographers can accurately assess whether an on-site FNA specimen is adequate.

Objective: To determine the accuracy of on-site cytopathology interpretation of EUS-FNA specimens by comparing endosonographers with a cytotechnologist.

Changing trends in endosonography: linear imaging and tissue are increasingly the issue.

The indications and uses of endoscopic ultrasound (EUS) are expanding. The role of EUS-guided fine needle aspiration (EUS-FNA) is considered an essential aspect of EUS practice. A significant change in the indications and technology used for EUS has occurred.

Endoscopic ultrasound for thoracic malignancy: a review.

Accurate cancer staging is critical in providing the most appropriate therapy for patients with lung cancer. The decision to attempt a curative surgery or avoid an unnecessary surgery is dependent on accurate staging. In the case of non-small-cell lung cancer (NSCLC), the most important parameters for optimal treatment and prognosis are the presence of cancer spread to the lymph nodes within the mediastinum and to distant organs.

EUS in the management of the patient with dysplasia in Barrett's esophagus.

Barrett's esophagus is the most important risk factor in the development of adenocarcinoma of the esophagus. Barrett's esophagus is generally regarded as the most significant complication of gastroesophageal reflux disease. Adenocarcinoma occurs more frequently in the setting of high-grade dysplasia.

Sleep patterns of cyclic parenteral nutrition, a pilot study: are there sleepless nights?

Background: Cyclic home parenteral nutrition (HPN) is 1 of the few medical therapies given during normal nocturnal sleep hours, and it is possible that infusion may alter normal sleep patterns. The aim of this pilot study was to evaluate the sleep patterns of 5 patients receiving HPN.

Methods: An Epworth sleep questionnaire was completed and wrist Actigraph data were collected before admission to the sleep laboratory.
