Does blood urea nitrogen level predict severity and high-risk endoscopic lesions in patients with nonvariceal upper gastrointestinal bleeding?
Nonvariceal upper gastrointestinal bleeding (UGIB) is a serious medical condition requiring prompt resuscitation and early endoscopic therapy in those with high-risk endoscopic lesions (HRLs). There are little or no data correlating sole blood urea nitrogen (BUN) level with the severity of nonvariceal UGIB or the presence of HRLs in the adult population. ⋯ In patients with nonvariceal UGIB, the BUN level at initial presentation is a weak predictor of the severity of UGIB as defined by ICU admission, but is not helpful in identifying patients with a HRL.

Pneumoscrotum is an unusual problem that is very rarely associated with gastrointestinal endoscopy procedures. It has been reported to occur after colonoscopy and polypectomy. The present paper describes the case of an 81-year-old man with benign pneumoscrotum that formed after polypectomy at the site of a previous rectal polyp. The pneumoscrotum was managed with conservative treatment.
