Cholesterolosis as a cause of acute pancreatitis.

Acute pancreatitis is an inflammatory condition of the pancreas manifesting with abdominal pain and elevated serum levels of pancreatic enzymes. Gallstones and chronic alcohol use are the most commonly described causes. A less studied cause is cholesterolosis, gallbladder polyps that cause mechanical obstruction of the sphincter of Oddi.

Dosimetric impacts of endorectal balloon in CyberKnife stereotactic body radiation therapy (SBRT) for early-stage prostate cancer.

Purpose: In SBRT for prostate cancer, higher fractional dose to the rectum is a major toxicity concern due to using smaller PTV margin and hypofractionation. We investigate the dosimetric impact on rectum using endorectal balloon (ERB) in prostate SBRT.

Materials And Methods: Twenty prostate cancer patients were included in a retrospective study, ten with ERB and 10 without ERB.
