In a recent paper Chen et al., using the longitudinal National Health Insurance Research of Taiwan database, compared 41 229 patients with peptic ulcer disease (PUD) and 41 229 matched controls. Because the cumulative incidence of varicella zoster infection in PUD patients was significantly higher compared with the control cohort (P< 0.001), the authors concluded that patients with PUD were at ...

It has been thirty years since the two Australians Robin Warren and Barry Marshall discovered Helicobacter pylori (H. pylori) in 1983 [1]. In order to fulfil the Koch's postulates, Marshall and Morris drank a solution which was a suspension of H. pylori. This produced gastritis from which the bacteria could be reisolated [2]. It will be interesting to see how the approach to treatment has progr...

Purpose To report the sequelae of and preventive strategies for selected lower urinary tract (LUT) complications, i.e., posterior urethral diverticulum (PUD), intraoperative LUT injuries, postoperative dysuria, fistula recurrence in male imperforate anus (IA) with rectourethral/rectovesical (RU/RV) after laparoscopy-assisted anorectoplasty (LAARP) or sagittal (PSARP). Methods 153 boys IA RU/RV ...

Abstract Mixtures of polyadipate 1,4-butanediol polyol and different small amounts (0.01–0.10 wt%) graphene oxide (GO) were added during the synthesis waterborne polyurethane urea dispersions (PUDs) carried out with acetone method. The addition 0.02–0.04 wt% GO increased T-peel strength plasticized poly (vinyl chloride)/PUD/plasticized chloride) joints whereas 0.05–0.10 wt% single lap-shear sta...

This systematic review examines the evidence for commonly employed strategies of managing patients with recurrent ulcer disease after acid-reducing operations. Particular attention is given to recent evidence relating Helicobacter pylori ( H. pylori ) and nonsteroidal anti-inflammatory drugs (NSAIDs) to ulcer recurrence after operative therapy. MEDLINE word searches of the literature from 1966 ...

introduction and aims: helicobacter pylori commonly is associated with gastritis: but only sometimes it causes clinically significant diseases such as gastric and duodenal ulcer. the development of disease depends on the virulence of the infecting h. pylori strain, the susceptibility of the host, and environment co-factors. the cytotoxin associated protein encoded by caga gene is an important v...

BACKGROUND Advancements in medical care for peptic ulcer disease (PUD) have reduced the need for invasive surgical procedures such as gastric resection (GR). Community-based PUD studies from a large sampling of PUD patients designed to analyze hospital resource use and outcomes after different surgical procedures have been rare. We aimed to exhaustively reappraise the risk factors and patient d...

Urban pickup and delivery (PUD) activities are important for logistics operations. Real operations general freight involve a high degree of complexity due to daily variability. Discrete-event simulation (DES) is method that can mimic real include stochastic parameters. However, realistic vehicle routing difficult build in DES models. The objective create model routing, which considers the drive...

Abstract Ultradiscretization enables us to construct a piecewise linear equation which approximates given subtraction-free difference equation. Recently proposed “ultradiscretization with parity variables” (pUD) can treat an subtraction. However, its solution may have infinite number of branches under some specific conditions. In this paper, solutions pUD for the hard-spring is investigated. Th...

Peptic ulcer disease (PUD) is predicted to affect between 0.1 and 0.3 percent of the population each year. PUD develops at a rate roughly 1% per year in Helicobacter pylori (H. pylori) infected persons, which 6 10 times higher than uninfected people. The prevalence increases with age both duodenal stomach ulcers. Two factors contribute peptic disease: H. infection use nonsteroidal anti-inflamma...
