Flat Spun Cocoon

Cocoon within an abdominal cocoon

Intestinal obstruction is a fairly common surgical emergency that usually occurs due to herniae, adhesions, or bands. Rarely, uncommon causes such as an abdominal cocoon are encountered, where part or all of the small intestine is encased within a thin membrane. We report one such case of abdominal cocoon, in whom, further encasement of the distal ileum was seen within a separate membrane.

Twisting Spun Knots

1. Introduction. In [5] Mazur constructed a homotopy 4-sphere which looked like one of the strongest candidates for a counterexample to the 4-dimensional Poincaré Conjecture. In this paper we show that Mazur's example is in fact a true 4-sphere after all. This raises the odds in favour of the 4-dimensional Poincaré Conjecture. The proof involves a smooth knot of S2 in S4 with unusual properties.

Tuberculous abdominal cocoon

Abdominal cocoon or sclerosing encapsulating peritonitis (SEP) is a rare cause of intestinal obstruction described mostly in young adolescent girls. Thick fibrotic peritoneum encasing the small bowel is a pathognomonic feature. Preoperative diagnosis is rare. A 37-year-old man with hypertension and chronic renal failure presented with complaints of vomiting and abdominal pain lasting a few days...

Preface - COCOON'2011

The 17th International Computing and Combinatorics Conference (COCOON’2011) took place in Dallas, Texas, USA, August 14–16, 2011. COCOON’2011 provided a forum for researchers working in the areas of Theoretical computer science, discrete mathematics, and their Applications. Papers accepted for presentations of the conference have been through a tough review process. Each paper received at least...
