Currarino syndrome is a rare congenital malformation characterised by the triad of: an anorectal malformation, sacral bony defect and presacral mass. One but possible anal canal duplication, anomaly which not only most distal also rarest form of digestive tract duplication. We present case four-year-old female who had complete including

Gastric duplication cysts comprise 2-7% of gastrointestinal duplications, rare congenital malformations that can be present at almost any part of the alimentary tract. They mostly present with gastrointestinal obstruction symptoms, ulceration, and painless hemorrhage. Symptoms include nausea, vomiting, and fullness sensation. Gastric duplications are mostly cystic in shape. Herein, we present a...

This paper studies Dehn surgery on a large class of links, called arborescent links. It will be shown that if an arborescent link L is suuciently complicated, in the sense that it is composed of at least 4 rational tangles T (p i =q i) with all q i > 2, and none of its length 2 tangles are of the form T (1=2q 1 ; 1=2q 2), then all complete surgeries on L produce Haken manifolds. The proof needs...

In this paper we construct OD(4pq(q+1); pq, pq, pq, pq, pq, pq, pq, pq) for each core order q ≡ 3(mod 4), r ≥ 0 or q = 1, p odd, p ≤ 21 and p ∈ {25, 49}, and COD(2q(q + 1); q, q, q, q) for any prime power q ≡ 1(mod 4) (including q = 1), r ≥ 0.

Let d(n; q) be the number of labeled graphs with n vertices, q N = ? n 2 edges, and no isolated vertices. Let x = q=n and k = 2q ?n. We determine functions w k 1, a(x), and '(x) such that d(n; q) w k ? N q e n'(x)+a(x) uniformly for all n and q > n=2.

A (p, q) connected graph is edge-odd graceful graph if there exists an injective map f: E(G) → {1, 3, ..., 2q-1} so that induced map f+: V(G) → {0, 1,2, 3, ..., (2k-1)}defined by f+(x)  f(x, y) (mod 2k), where the vertex x is incident with other vertex y and k = max {p, q} makes all the edges distinct.

In this note we construct a new infinite family of (q− 1)-regular graphs of girth 8 and order 2q(q − 1)2 for all prime powers q > 16, which are the smallest known so far whenever q − 1 is not a prime power or a prime power plus one itself.
