Considerable confusion surrounds the use of the term surveillance in the context of public health but the principles underlying all uses are as old as epidemiology itself. William Farr has contributed more than anyone else to the development of these principles and to the demonstration of their value in practice on a large scale. This paper re-examines the basic tenets which guided him and the ...

BACKGROUND To offer vaginal birth after cesarean (VBAC) in a hospital setting is recommended in international guidelines, but offering VBAC in out-of-hospital settings is considered controversial. This study describes neonatal and maternal outcomes in mothers who started labor in German out-of-hospital settings. METHOD In a retrospective analysis of German out-of-hospital data from 2005 to 20...

BACKGROUND AND OBJECTIVES: Very low grid power penetration in some urban areas has led to telecoms companies investing massively in the deployment of diesel generators (DGs). These deployments have led to diesel and waste oil spill at base transceiver station (BTS) sites during maintenance cycles, impacting the environment and human activities. The objective of this study is to...

This article presents a comparison of screw-retained and cement-retained implant prostheses based on the literature. The advantages, disadvantages, and limitations of the 2 different types of restorations are discussed, because it is important to understand the influence of the attachment mechanism on many clinical aspects of implant dentistry. Several factors essential to the long-term success...

screw-retained implant restorations have an advantage of predictable retention as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. screw-retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. the purpose of this study is to descr...

Initial Cadmium (Cd) isotope fractionation studies in cereals ascribed the retention of Cd and its light isotopes to binding sulfur (S). To better understand relation S soils plants, we combined XAS speciation analyses soil-rice systems that were rich S. The included distinct water management (flooded vs. non-flooded) rice accessions with (excluder) without (non-excluder) functional membrane tr...

A fixed dental prosthesis can be secured to an endosseous implant via cementation (using a provisional or definitive cement) on an implant abutment that is screw retained to the implant or directly in the implant via screw retention. The clinical decision as to which retention system best suits the individual patient depends on several factors. The aim of this review is to present a detailed ov...
