Саse reроrt оf fetal liver cirrhosis due to gestational alloimmune liver disease in а primigravida femаle, in north east region of India

Fetal liver failure is a major cause of neonatal morbidity and mortality, presenting as acute liver failure and/or congenital cirrhosis. There are several causes of fetal liver failure and early diagnosis is mandatory to elucidate the etiology and determine a specific treatment or the best management strategy. Gestational alloimmune liver disease associated with neonatal hemochromatosis (GALD-NH) is a rare cause of fetal liver failure. It should be considered in any neonate with fetal signs of liver failure with no other identifiable causes. GALD-NH is often diagnosed late and patients are therefore referred late to specialized centers, delaying treatment. This case highlighted the consequences of late diagnosis and treatment of GALD-NH and emphasizes the importance of a high grade of suspicion of this disease in order to refer the patient to a specialized center soon enough to perform the appropriate treatment

Querying for the Largest Empty Geometric Object in a Desired Location

We study new types of geometric query problems defined as follows: given a geometric set $P$, preprocess it such that given a query point $q$, the location of the largest circle that does not contain any member of $P$, but contains $q$ can be reported efficiently. The geometric sets we consider for $P$ are boundaries of convex and simple polygons, and point sets. While we primarily focus on circles as the desired shape, we also briefly discuss empty rectangles in the context of point sets.Comment: This version is a significant update of our earlier submission arXiv:1004.0558v1. Apart from new variants studied in Sections 3 and 4, the results have been improved in Section 5.Please note that the change in title and abstract indicate that we have expanded the scope of the problems we stud

Left ventricular mass: Myxoma or thrombus?

Patient with embolic episode should always be evaluated for cardiac mass. Mass in left ventricular can be a myxoma or thrombus even in a normal functioning heart . In either case, mobile mass with embolic potential should be surgically resected

On the construction of a generalized Voronoi inverse of a rectangular tessellation

We introduce a new concept of constructing a generalized Voronoi inverse (GVI) of a given tessellation τ of the plane. Our objective is to place a set S i of one or more sites in each convex region (cell) t i ∈ τ , such that all the edges of τ coincide with the edges of Voronoi diagram V (S), where S = ∪ i S i, and Ai, j, i= j, S i ∩S j = θ. In this paper, we study the properties of GVI for the special case when T is a rectangular tessellation and propose an algorithm that finds a minimal set of sites S. We also show that for a general tessellation, a solution of GVI always exists

Approximate shortest descent path on a terrain

A path from a point s to a point t on the surface of a polyhedral terrain is said to be descent if for every pair of points p = (x(p), y(p), z(p)) and q = (x(q), y(q), z(q)) on the path, if dist(s,p) z(q), where dist(s,p) denotes the distance of p from s along the aforesaid path. Although an efficient algorithm to decide if there is a descending path between two points is known for more than a decade, no efficient algorithm is yet known to find a shortest descending path from s to t in a polyhedral terrain. In this paper we propose an (1 + ε-approximation algorithm running in polynomial time for the same

The discrete Voronoi game in a simple polygon

In this paper we consider a competitive facility location problem played between two players P1 and P2. Let P be a simple polygon with m vertices. Consider a set of users, U modeled as points in the interior (excluding the boundary) of P. Initially P1 chooses a point inside P (including the boundary) to place a facility. Following this P2 chooses another point inside P and places a facility. Given these facilities a user u∈U is served by its nearest facility, where distances are measured by the geodesic distance in P. The objective of each player is to maximize the number of users they serve. We show that for any given placement of a facility by P1, an optimal placement for P2 can be computed in O(m+n(log⁡n+log⁡m)) time. We also provide a polynomial-time algorithm for computing an optimal placement for P1
