Acute appendicitis is the most frequent surgical abdominal emergency, but its etiology remains poorly understood. Histological examination of the appendix, following its removal due to acute appendicitis, consistently shows features in common with ...

Acute Appendicitis: Clinical Laboratory, Laparoscopic, Pathomorphological Parallels
Introduction. Acute appendicitis takes the first place in incidence among acute surgical disorders of the abdominal cavity organs. While many issues of the diagnosis and treatment strategy of this disease have been studied in detail, the diagnosis of ...

On the hot spots conjecture for acute triangles [PDF]
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.

Acute appendicitis: An overview
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 ...

No acute tetrahedron is an 8-reptile [PDF]
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 ...

Acutely Triangulated, Stacked, and Very Ununfoldable Polyhedra [PDF]
We present new examples of topologically convex edge-ununfoldable polyhedra, i.e., polyhedra that are combinatorially equivalent to convex polyhedra, yet cannot be cut along their edges and unfolded into one planar piece without overlap. One family of examples is acutely triangulated, i.e., every face is an acute triangle. Another family of examples is

Abstract Health system performance assessment (HSPA) is essential for health planning and to improve population health. One of the HSPA domains is related to effectiveness, which can be represented considering different dimensions. Composite indicators can be used to summarize complex constructs involving several indicators. One example of such efforts

Prospective Observational Study on acute Appendicitis Worldwide (POSAW)
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.

Acute Triangulations of the Cuboctahedral Surface [PDF]
In this paper we prove that the surface of the cuboctahedron can be triangulated into 8 non-obtuse triangles and 12 acute triangles. Furthermore, we show that both bounds are the best possible.

Abstract Negative pressure wound therapy (NPWT) is a very effective method in the treatment of dehiscent, infected, and non‐healing wounds. Difficult wound healing occurs especially in late pregnancy due to the rapid enlargement of the uterus and the constantly increasing tension of the entire abdominal wall.
