Inverted Meckel's diverticulum as a cause of occult lower gastrointestinal hemorrhage.

Meckel's diverticulum is a common asymptomatic congenital gastrointestinal anomaly, but rarely it can present with hemorrhage. Over the last few years inverted Meckel's diverticulum has been reported in the literature with increasing frequency as an occult source of lower gastrointestinal hemorrhage. Here, we report a case of a 54-year-old male, who was referred for surgical evaluation with persistent anemia and occult blood per rectum after a work up which failed to localize the source over 12 mo, including upper and capsule endoscopy, colonoscopy, enteroclysis, Meckel scan, and tagged nuclear red blood cell scan.

The effects of restricted work hours on clinical training.

Resident education has changed dramatically over the past 10 years.

This manuscript attempts to answer this question through a survey performed to assess the perception of residents about duty-hour restrictions and the potential effect on residents' clinical exposure.

Metaplastic breast cancer: clinical features and outcomes.

Metaplastic carcinoma of the breast, a neoplasm with both epithelial and mesenchymal elements, represents less than 1 per cent of all breast cancer. We reviewed the records of all patients diagnosed with localized metaplastic breast cancer from 1991 to 2003 at our institution. We identified 21 patients.

Metastatic meningioma to the liver successfully treated with a wedge resection and radiation therapy: report of a case.
