A 44-year old male patient with a past medical history of a complete surgical excision of pelvic hydatid cyst two years previously presented with constant pelvic floor pain and plasma IgG anti-echinococcal antibody titres of 14.27 U/mL. Based on that and the imaging findings of abdominal ultrasound (US), Computed Tomography (CT) and Magnetic Resonance (MR) the diagnosis of a recurrent retrorect...

INTRODUCTION Currarino syndrome (CS) is characterized by the triad of anorectal malformations, sacral bone defects, and presacral mass in which an autosomal dominant inheritance has been described. The surgical community has a little no knowledge of CS in adults, apart from, perhaps, a small number of paediatric surgeons. Therefore, we sought to describe this unusual cause of anal fistula. PR...

we study umbilic (space-like) submanifolds of pseudo-riemannian space forms, then define totally semi-umbilic space-like submanifold of pseudo euclidean space and relate this notion to umbilicity. finally we give characterization of total semi-umbilicity for space-like submanifolds contained in pseudo sphere or pseudo hyperbolic space or the light cone.a pseudo-riemannian submanifold m in (a ps...

in this paper, we formalize the menger probabilistic normed space as a category in which its objects are the menger probabilistic normed spaces and its morphisms are fuzzy continuous operators. then, we show that the category of probabilistic normed spaces is isomorphicly a subcategory of the category of topological vector spaces. so, we can easily apply the results of topological vector spaces...

defining space by dividing it to inside and outside is one of human’s ways to recognize his positionin environment. architecture is created to response to this need for inside/outside spaces. design of inside and outsidespaces and relation between them always has been one of necessities for definition and limitation of human livingspaces, but little attention to relation of this two spatial rea...

in this paper we obtain lower and upper estimates for the essential norms of generalized composition operators from weighted dirichlet spaces or bloch type spaces to $q_k$ type spaces.

the study of design and formation of urban space focuses on interaction of human and environment. this is an attractive subject that considers as interdisciplinary debates. thinkers of urban studies pay attention to this matter empirically and theoretically in order to provide a desirable space for human being. this research is based on the theories of urban studies and urban sociology and so o...

Abstract Background Malignant transformation of tailgut cysts (benign retrorectal cysts) into Neurodendocrine tumours (NETS) is extremely rare with less than 30 reported cases in the literature. A tiny proportion these report early recurrence (within 2 years) and to our knowledge none have delayed 6 years after primary resection. Case history We a 55-year-old male who underwent laparoscopic exc...
