Amoebic chronic appendicitis: a rare entity
Journal of Pathology of Nepal, 2016 Rarely intestinal parasites can cause acute appendicitis. Amoebic appendicitis is rare and infection with Entamoeba Histolytica usually develops as an extension of caecal infection.

Acute triangulations of polyhedra and R^n [PDF]
arXiv, 2009 We study the problem of acute triangulations of convex polyhedra and the space R^n. Here an acute triangulation is a triangulation into simplices whose dihedral angles are acute. We prove that acute triangulations of the n-cube do not exist for n>=4. Further, we prove that acute triangulations of the space R^n do not exist for n>= 5.

Acute Triangulation of Constant Curvature Polygonal Complexes [PDF]
arXiv, 2022 We prove that every 2-dimensional polygonal complex, where each polygon is given a constant curvature metric and belongs to one of finitely many isometry classes can be triangulated using only acute simplices. There is no requirement on the complex to be finite or even locally finite.

British Journal of Surgery, 2018 The traditional fear that every case of acute appendicitis will eventually perforate has led to the generally accepted emergency appendicectomy with minimized delay.

Acute appendicitis: An overview
East African Medical Journal, 2009 To provide an overview of the changing epidemiology of acute appendicitis in the developed and developing countries and the presumptive reasons.Major published series of the last two decades were reviewed using Medline Search and Index Medicus. The myriad of diagnostic approaches currently employed to reduce the hitherto high rates of negative ...

On the hot spots conjecture for acute triangles [PDF]
arXiv, 2013 We show that the hot spots conjecture of J. Rauch holds for acute triangles if one of the angles is not larger than $\pi/6$. More precisely, we show that the second Neumann eigenfunction on those acute triangles has no maximum or minimum inside the domain.

Prospective Observational Study on acute Appendicitis Worldwide (POSAW)
World Journal of Emergency Surgery, 2018 BackgroundAcute appendicitis (AA) is the most common surgical disease, and appendectomy is the treatment of choice in the majority of cases. A correct diagnosis is key for decreasing the negative appendectomy rate.

No acute tetrahedron is an 8-reptile [PDF]
arXiv, 2015 An $r$-gentiling is a dissection of a shape into $r \geq 2$ parts which are all similar to the original shape. An $r$-reptiling is an $r$-gentiling of which all parts are mutually congruent. This article shows that no acute tetrahedron is an $r$-gentile or $r$-reptile for any $r < 9$, by showing that no acute spherical diangle can be dissected into ...

International Journal of Colorectal Disease, 2019 Acute appendicitis may present as uncomplicated and complicated and these disease forms differ both epidemiologically and clinically. Complicated acute appendicitis has traditionally been defined as an appendicitis complicated by perforation or a ...
