An innovative impression technique for fabrication of a custom made ocular prosthesis.

Various impression and fitting techniques have been described in the past for restoring ocular defects. The present article describes a new direct impression technique for recording and rehabilitating ocular defects, by custom-made ocular prosthesis. All the techniques described in the history, mainly concentrated in recording the tissue surface of the defect, which made it difficult to contour the palpebral surface resulting in the poor esthetics of the prosthesis.

The potential of recurrent epidemics and pandemics in a highly mobile global society.

The aim of this study was to demonstrate how latent epidemics can potentially evolve into a pandemic instantaneously due to globally mobile human population in recent times, as can be seen in the ongoing Ebola epidemic in West Africa. Selected cases of current epidemics are used in this study to identify emergent patterns. These cases exemplify the need for a comprehensive analysis of infectious diseases and serve as an initial stage when developing appropriate strategies in improving epidemic management.

Vulnerability and risk perception in the management of HIV/AIDS: Public priorities in a global pandemic.

Understanding the way perception of risk is shaped and constructed is crucial in understanding why it has been so difficult to mitigate the spread of HIV/AIDS. This paper uses the Pressure and Release (PAR) model, used to predict the onset of natural disasters as the conceptual framework. It substitutes vulnerability and risk perception as the trigger factors in the model, in making the case that HIV/AIDS can be characterized as a slow onset disaster.
