Neuroendocrine differentiation is common in adenocarcinomas of the stomach and colon and may be associated with a slightly better prognosis in gastric adenocarcinoma. We studied neuroendocrine differentiation in esophageal adenocarcinomas and associated Barrett's esophagus (BE) to determine association with patient outcome. Fifty-eight cases of esophageal adenocarcinoma (15 biopsies, 43 resections) from 52 patients were stained with a monoclonal antibody to chromogranin (CG). Medical records were reviewed for tumor stage, response to therapy, and patient survival. Thirty-two patients received radiation and chemotherapy, and four received radiation. Twelve of 58 (20.7%) esophageal adenocarcinomas contained scattered CG-positive cells. Tumors with CG-positive cells were moderately to poorly differentiated, and many consisted of large cribriform glands, similar to intestinal-type adenocarcinomas. One case of small cell carcinoma of the esophagus was weakly CG positive; another was negative. Neuroendocrine differentiation was retained in lymph node metastases in two cases but lost in three other cases. In 10 CG-negative primary tumors, lymph node metastases were also negative.

OBJECTIVE.Previous Based on these numbers, overall sensitivity using the OAR was 99% (confidence interval, 95-100%), and specificity was 22%. We found an overall 16% reduction in the number of ankle films ordered. CONCLUSION.When implemented at a level I trauma center. the OAR can adequately screen for ankle fractures.

For most measures of epilepsy management, symptoms of anxiety and/or depression do not alter epilepsy care; however, drug resistant epilepsy patients with anxiety and/or depression symptoms may be more likely to miss outpatient appointments, and those with the highest burden of psychiatric symptoms may be admitted more frequently for inpatient services compared to controls.
