BACKGROUND Despite the importance of mortality data for effective planning and monitoring of health services, official reporting systems rarely capture every death. The completeness of death reporting and the subsequent effect on mortality estimates were examined in six municipalities of Bohol province in the Philippines using a system review and capture-recapture analysis. METHODS Reports of...

The benefits from the use of the features attributes and the availability of different types of features on images (pointor linear-features) have raised the importance of using different feature-based transformation models for satellite image registration and terrain modeling. In the last decades, several research works have been conducted to facilitate the use of pointor linear-feature based t...

background and aims. dental practitioners have numerous methods to control anxiety and pain in children, and distracting the child appears to be the most common technique used for behavior management during dental procedures. the aim of the present study was to evaluate the influence of using virtual reality eyeglasses on severity of pain and anxiety during dental procedures in pediatric patien...

The usual academic and commercial CAD systems in construction design, only allow the visualization of the final stage of the project, namely, as building three-dimensional (3D) models and walk-through (by its inside and outside). Current computer tools and models are not able to follow changes in the geometry of a building or structure during the construction process. A Virtual Reality technolo...

Most developing countries do not have fully effective civil registration systems to provide necessary information about population health. Interim approaches—both innovative strategies for collection of data, and methods of assessment or estimation of these data—to fi ll the resulting information gaps have been developed and refined over the past four decades. To respond to the needs for data f...

This study explores the effects of early-life and middle-life conditions on exceptional longevity using two matched case-control studies. The first study compares 198 validated centenarians born in the United States between 1890 and 1893 to their shorter-lived siblings. Family histories of centenarians were reconstructed and exceptional longevity validated using early U.S. censuses, the Social ...

TO THE EDITOR The incidence of nonmelanoma skin cancer (NMSC) increases worldwide, partly due to the population ageing. Therefore, any impact of NMSC on mortality would have major public health implications. Data on mortality after NMSC are few and remain controversial and the role of co-morbidity has not been clarified. We therefore assessed the association between NMSC in Denmark and mortalit...
