Background: Pain is one of the side effects of episiotomy. The virtual reality (VR) is a non-pharmacological method for pain relief. The purpose of this study was to determine the effect of using video glasses on pain reduction in primiparity women during episiotomy repair.Methods: This clinical trial was conducted on 30 primiparous parturient women having labor at Omolbanin Hospital (Mashhad, ...

Introduction The latest report on mortality in Bolivia was issued in 1990. The three leading causes of death were infectious and parasitic diseases (23.9%), diseases of the circulatory system (19.5%), and diseases of the respiratory tract (14%), followed by accidents and violence (9.8%), disorders of the digestive system (8.6%), affections originating in the perinatal period (7.4%), and tumors ...

BACKGROUND The objective of this study was to formally investigate the onset of the Seascale cluster of childhood and young person's cancer. This has not previously been attempted. METHODS A mortality study within the Whitehaven registration district was set up and death records were abstracted for 1906-1970. They were categorized as death from leukaemias, lymphomas, other cancers and all oth...

Official Dutch perinatal mortality rates are based on birth and death certificates. These civil registration data are not detailed enough for international comparisons or extensive epidemiological research. In this study, we linked and extrapolated three national, incomplete, professional registers from midwives, obstetricians and paediatricians, containing detailed perinatal information. This ...

The objective of this paper is to present a grasping registration technique by using Virtual Reality technologies. In this context, an individual interacts with a virtual world by means of several devices which are integrated into a common architecture. A 6 DOF tracking system gives the position of the user in the scene and a VR glove provides the flexion angles of the fingers of a virtual hand...

We describe an experimental prototype system in which a virtual protractor is used to measure three dimensional relationships between objects. The objects being measured are not modeled explicitly using surface or procedural geometric definitions in the traditional sense, but rather are perceived by a viewer who looks at stereo image pairs. In contrast, the virtual instrument itself is represen...

In mobile augmented/virtual reality (AR/VR), real-time 6-Degree of Freedom (DoF) motion tracking is essential for the registration between virtual scenes and the real world. However, due to the limited computational capacity of mobile terminals today, the latency between consecutive arriving poses would damage the user experience in mobile AR/VR. Thus, a visual-inertial based real-time motion t...

In this paper, we present an automated method for colon registration. The method uses dynamic programming to align data defined on colon center-line paths, as extracted from the prone and supine scans. This data may include information such as path length and curvature as well as descriptors of the shape and size of the colon near the path. We show how our colon registration technique can be us...
