Background: While the benefits of cone-beam computed tomography (CBCT) are well known in maxillofacial imaging, the use of this modality is not risk-free.Objective: The aim of this study was to evaluate the exposure doses received by patients during maxillofacial imaging with CBCT.Methods: Entrance surface dose (ESD) was measured by using thermoluminescent dosimeters (TLDs) attached to the eyes...

A continuous update of authoritative spatial databases is highly demanding task in both aspects, technical and financial. In the same time, alternative modalities to collect content, in particular spatial content, have achieved a certain maturity and must be considered as they may leverage the cost of updating authoritative spatial databases (Al-Bakri, 2010). This alternative data known as Volu...

The Cryptococcus gattii complex has been recognized as an endemic pathogen since the 1990s and has caused multiple outbreaks since then. Cryptococcal meningitis (CM) is a globally occurring invasive mycosis associated with significant morbidity and mortality, including papilledema and visual loss. We present a case of CM caused by C. gattii sensu stricto (AFLP4/VGI) that was complicated by visu...

Abstract. VGI projects include geographic information, which are the product of many unorganized volunteers, making it a challenge to ensure quality their information. In this field study, several researchers have suggested using intrinsic factors evaluate instead explicit methods such as comparing with real or reference datasets. addition, measurement reliability contributors an essential fact...
