Regularity of the edge ideals of perfect [ν,h]-ary trees and some unicyclic graphs.

We compute the Castelnuovo-Mumford regularity of the quotient rings of edge ideals of perfect [ν,h]-ary trees and some unicyclic graphs.

Ileo-ileal intussusception due to inflammatory fibroid polyp: a rare cause of small bowel obstruction in adults.

Intussusception in adults is a relatively uncommon occurrence for a cause of bowel obstruction, which can present acutely, chronically or in an acute on chronic fashion. It is clinically concerning because of the possibility of cancer acting as a lead point. Small bowel tumours are rare, mostly detected incidentally with small bowel obstruction. Inflammatory fibroid polyp (IFP) is a rare benign tumour of the small bowel, either detected incidentally on imaging or endoscopy carried out for other reasons, or presents with acute features. We present a case of small bowel intussusception caused by IFP within the distal third of the ileum as a leading point. The patient presented acutely with small bowel obstruction, on a background of recurrent non-specific abdominal pain over the preceding month, and the computed tomography scan revealed an intussusception that was timely managed with a laparoscopy-assisted small bowel segmental resection.
