A female baby of one-and-a-half-year old presented with extrusion of ventriculoperitoneal (VP) shunt through umbilicus. On exploration, the urachal remnant was found perforated by VP shunt and the tube exteriorized through umbilicus. Child was managed successfully with excision of urachal remnant, removal of VP shunt, antibiotic treatment and re-insertion of shunt.

I) The author should reflect the view points of the oppositions and any opponent of this idea. There are some misleading usages of references. For example in reference11 in Dr. M Farhadi et al's article, Song et al found that children with history of initial tympanostomy tube (TT) insertion had a longer extrusion time. Also patients with serous effusion had the shortest extrusion time (1). Glei...

A new severe plastic deformation for manufacturing Al/Mg bimetallic tube called the TES (tube extrusion shearing) process, which combines direct with two-step shearing, has been developed to manufacture tube. Load evolution stroke at different temperatures simulated by establishing three-dimensional finite element simulation of process tubes. To explore mechanisms during microstructures and pha...

In order to promote the comprehensive utilization of corn straw and development field water-saving irrigation technologies, a kind underground composite pipe-forming device mixed with soil extrusion molding was designed. The key extrusion-forming components affecting forming rate pipe were optimized by taking diameter winch blade, shaft winch, pitch as variables output power test indices. best ...
