Objective: To compare the objective and subjective cure rates of suburethral plication versus TVT-O in women with SUI. Methods: This is a randomized comparative trial done at a university hospital. Patients recruited were chosen to have urodynamic evidence of genuine SUI. They were randomized to have either suburethral plication or TVT-O. Patients were assessed preoperatively and postoperativel...

background: injured phrenic nerve secondary to cardiac surgeries is the most common cause of diaphragmatic paralysis (dp) in infants. the aim of this study was to determine the risk factors for dp caused by congenital heart defect corrective surgeries in pediatrics. methods: this cross-sectional study, conducted in a 2-year period (2006 – 2008), included 451 children with congenital heart disea...

background: laparoscopic gastric plication (lgp) is a technique in the restrictive category of bariatric procedures that reduces the gastric volume. nausea and vomiting are the most common complications after this procedure. the goal of this research is to determine the preventive effective dose of promethazine on postoperative nausea and vomiting after laparascopic gastric placation methods: a...

Kelly-width is a parameter of directed graphs recently proposed by Hunter and Kreutzer as a directed analogue of treewidth. We give several alternative characterizations of directed graphs of bounded Kelly-width in support of this analogy. We apply these results to give the first polynomial-time algorithm recognizing directed graphs of Kelly-width 2. For an input directed graph G = (V,A) the al...

Annealed metals are surprisingly difficult to cut, involving high forces and an unusually thick "chip." This anomaly has long been explained, based on ex situ observations, using a model of smooth plastic flow with uniform shear to describe material removal by chip formation. Here we show that this phenomenon is actually the result of a fundamentally different collective deformation mode--sinuo...

Using high-resolution, in situ imaging of a hard, wedge-shaped model asperity sliding against a metal surface, we demonstrate a new mechanism for particle formation and delamination wear. Damage to the residual surface is caused by the occurrence of folds on the free surface of the prow-shaped region ahead of the wedge. This damage manifests itself as shallow crack-like features and surface tea...

The diaphragm is grasped, and as much of the anterior diaphragm as possible is pulled into a retaining clamp. This maneuver is easier to perform for the right diaphragm than the left diaphragm, owing to the risk of incorporating viscera on the left. Upon initial placement of the clamp, it is evident that all of the diaphragm that would optimally be resected cannot occur in one application. This...
