Quantification of the visceral and subcutaneous fat by computed tomography: interobserver correlation of a single slice technique.

Purpose: To assess the interobserver reproducibility of the quantification of the visceral and subcutaneous fat by computed tomography from an umbilical slice and study the effect of the level of the slice (slice going through the navel versus a slice going through disc L3-L4).

Materials And Methods: Forty-four breast cancer patients who had a CT-scan were included in this study. This is a double blind (junior versus senior) retrospective study to determine the interobserver reproducibility.

Transcatheter embolization as the new reference standard for endoscopically unmanageable upper gastrointestinal bleeding.

Acute nonvariceal upper gastrointestinal bleeding (UGIB) is a major medical emergency problem associated with significant morbidity and mortality. Endoscopy is considered the first method of choice to detect and treat UGIB. Endoscopic therapy usually achieves primary hemostasis, but 10%-30% of these patients have repeat bleeding.
